(26) The following embodiments are examples. Although the description refers to one or more embodiments, that does not necessarily mean that each reference relates to the same embodiment or that the features apply only to one single embodiment. Simple features from various embodiments may also be combined to provide other embodiments.

FIRST EMBODIMENT

(27) FIGS. 1 and 2 show schematic perspective views from above and beneath respectively of a mounting base 1 for a wired electrical component.

(28) This mounting base 1 has, for example, the shape of a disk or of a pellet, but other shapes are conceivable, for example square or oval, without departing from the scope of the present invention.

(29) The shape of the mounting base 1 is configured to allow the mounting base 1 to be mounted for example on another support, for example a wall, a fabric or a canvas, a rigid or flexible casing, etc. For that purpose, provision may also be made for the mounting base 1 to be equipped with lateral fixing lugs (not depicted), for screwing or bonding of the mounting base 1.

(30) The mounting base 1 is, for example, made of plastic, for example using injection molding.

(31) The mounting base 1 comprises a housing 3 to receive an electrical component 5 equipped with at least one crimping electrical contact 7 (see FIG. 4).

(32) In this exemplary embodiment, the electrical component 5 is, for example, a light emitting diode 9.

(33) In other embodiments, the electrical component may for example be a sensor (a temperature sensor, magnetic and/or electrical field sensor, light sensor/photodiode), a battery, an emitter/receiver, for example an antenna, etc. In general terms, this is an electrical component measuring a few mm across, which needs to be connected to individual electrical wires.

(34) The housing 3 in this particular instance is a through-opening 11, for example square in shape and having, on the front face 13 of the mounting base 1, a shape 15 that flares toward the top (which means to say in a direction substantially parallel to the emission direction of the diode), encouraging the light emitting diode 9 to emit a cone of light when this diode is mounted in the mounting base 1.

(35) In a more sophisticated version, provision may be made for the flared shape 15 to be, for example, metalized, in order to act as a reflector.

(36) What is meant by the front face 13 is that face of the mounting base 1 from which a light emitting diode 9 may emit light when such a diode 9 is mounted in the mounting base 1. The rear/front direction of the mounting base 1 is therefore substantially parallel to the direction of emission of such a light emitting diode 9.

(37) The front face 13 also corresponds to the face of the mounting base 1 that is intended to be at least partially visible when the mounting base 1 is mounted on a support such as a fabric or garment. In particular, this front face 13 is intended to be fixed, for example by bonding, to the support, such as a fabric or garment, in such a way that the part of the front face 13 of the mounting base 1 that has the housing 3 and the flared shape 15 projects with respect to this support, notably by passing through a corresponding hole of complementary shape made in the support intended to receive the mounting base 1.

(38) As an alternative or in addition, this front face 13 may be fixed to an assembly roundel 60 (visible in FIG. 22) for example by ultrasonic welding so as to sandwich the support such as a fabric or garment between this assembly roundel 60 and the mounting base 1. The part of the front face 13 of the mounting base 1 that has the housing 3 and the flared shape 15 in this case is then also able to pass through the corresponding hole of complementary shape in the assembly roundel 60.

(39) As can be better seen in FIG. 2, the mounting base 1 comprises at least one, and in this instance two, grooves 17. The groove or grooves 17 are advantageously formed on the rear face 18 of the mounting base 1. What is meant by the rear face 18 is the opposite face of the mounting base 1 to the front face 13. This rear face 18 is intended no longer to be visible from the outside when the mounting base 1 is mounted on a garment for example.

(40) In general, the mounting base 1 has as many grooves 17 as there are electrical wires to be connected to the electrical component 5.

(41) Each groove 17 has in cross section a particular shape depicted according to one embodiment in FIG. 3.

(42) Thus, the groove 17 in cross section has, on the one hand, a portion 19, for example of substantially cylindrical overall shape, configured to receive an electrical wire 21 (see FIG. 5) and, on the other hand, an access canal or access passage 23 for the crimping electrical contact 7. As may be seen in FIGS. 1 to 3, the access canal 23 in this example is oriented perpendicular to the axis 24 of the groove 17, in this instance the longitudinal axis 24 of the groove 17. The access canal 23 has, in the example illustrated, a width L.sub.A that is smaller than the maximum width L.sub.MAX of the portion 19 here of substantially cylindrical overall shape. This maximum width L.sub.MAX corresponds in the example illustrated to the diameter of the portion 19.

(43) Thus, when a suitable electrical wire 21 having, for example, a diameter slightly smaller than the width L.sub.MAX but greater than the width L.sub.A of the access canal 23 is inserted, it is guided longitudinally along the groove 17 without being able to leave the groove.

(44) The width L.sub.A of the access canal 23 is dimensioned so that it is slightly greater than the width L.sub.C (see FIG. 4) of the crimping electrical contact 7.

(45) In the exemplary embodiment of FIG. 3, the groove 17 has a convergent bottom 25 opposite to the access canal 23. This convergent bottom 25 is made up of two inclined straight slopes 27 which end on a straight bottom 29 parallel to the rear face 18 of the mounting base 1.

(46) This convergent bottom 25 with its inclined slopes 27 acts as a crimping shape when the crimping electrical contact 7 is inserted into the groove 17.

(47) Moreover, the mounting base 1 comprises a peripheral edge 31 partially covering the groove 17. This peripheral edge 31 serves firstly as a retainer to retain the electrical wires 21, notably to prevent them from being pulled out in the direction perpendicular to the rear face 18 of the mounting base 1 and secondly as a retaining edge so that a layer of encapsulant can be poured in after the electrical component 5 has been mounted (this will be explained later on).

(48) FIG. 4 shows a schematic perspective view of the electrical component 5 equipped with at least one and, in this instance with two, crimping electrical contacts 7.

(49) As explained hereinabove, the electrical component 5 is, for example, a light emitting diode 9.

(50) The crimping electrical contacts 7 each comprise a region 33 (visible in FIG. 7) that is flat, for example welded to the power supply terminals of the diode 9 and a part that has crimping spikes 35.

(51) In this example, the two electrical contacts 7 are parallel to one another.

(52) One exemplary embodiment of a way of mounting a module such as a lighting module 37 (see FIG. 9) will now be described with reference with FIGS. 5 to 9.

(53) This lighting module 37 comprises a light emitting diode 9 of FIG. 4 and a mounting base 1 as depicted in FIGS. 1 to 3.

(54) FIG. 5 is an exploded schematic perspective view of a lighting module according to the invention prior to assembling, with the mounting base 1, the light emitting diode 9 equipped with two crimping electrical contacts 7 and two electrical wires 21.

(55) In a first step, an electrical wire 21 is passed into each groove 17 in the direction of the arrow F1.

(56) Next, the diode 9 equipped with its two crimping contacts 7 with the crimping spikes 35 directed toward the associated grooves 17 is inserted via the rear face 18 of the mounting base 1 in the direction of the arrow F2 so that on insertion, crimping onto the electrical wires 21 is achieved.

(57) The mounting base 1 therefore acts both as a support or protective casing for the electrical component 5 and as a crimping counterform in order to make the electrical connection with the electrical wires 21.

(58) During this insertion, the spikes 35 will pierce through the electrical wires 21 in such a way as to establish an electrical contact with the strands of the core 39 (see FIG. 8) of the electrical wires 21, then the spikes 35 will deform inwards as they encounter one of the inclined straight slopes 27. This deformation will also allow firm mechanical retention between the electrical wire 21 on the one hand and the crimping electrical contacts 7 on the other.

(59) FIG. 7 shows the light emitting diode 9 crimped onto the two electrical wires 21.

(60) According to an optional step, a transparent resin 40 is then poured over the front face 13 of the mounting base 1, so as to cover the diode 9 and obtain a domed shape which acts as a lens for the diode 9.

(61) A layer of encapsulant (not visible in the figures) for example is also poured over the rear face 18 of the mounting base 1.

(62) This then yields a lighting module 37 that is sealed and protected against moisture and dust.

(63) FIG. 9 shows the lighting module 37 in the form of a pellet the electrical wires 21 of which can easily be connected now, for example, to a power supply unit (not depicted).

(64) Such a module 37, for example a lighting module, can then be fixed to a support such as a fabric or garment. As stated previously, the module 37 may be fixed by the front face 13 of the mounting base 1 against the support so that at least part of the front face 13 exhibiting the housing 3 passes through a corresponding and complementary hole made in the support.

(65) The mounting base 1 may be attached to the support by bonding the front face 13 to the support.

(66) As an alternative or in addition, in order to fix the mounting base 1 on a support, it is possible to provide an assembly roundel 60 (cf. FIGS. 22 and 23) arranged against the support and the mounting base 1 is then arranged in such a way that the support is sandwiched between the mounting base 1, more specifically the front face 13 of the mounting base 1, and this assembly roundel 60. In this case, the part of the front face 13 that has the housing 3 also passes through a corresponding hole of complementary shape in the assembly roundel 60. The mounting base 1 and the assembly roundel 60 may be fixed by ultrasonic welding.

(67) Of course, the order in which some of the steps described hereinabove are performed could be interchanged.

SECOND EMBODIMENT

(68) FIGS. 10 to 11 show another embodiment of the mounting base and of the light emitting diode 9 which differs from that of FIGS. 1 to 9 and which is particularly advantageous for placing several lighting modules 37 in series because it comprises two pairs of grooves 17 on each side of the housing 3 and because the crimping electrical contacts 7 have crimping spikes on each side of the light emitting diode 9. This second embodiment is well suited for mounting several lighting modules in parallel.

(69) Assembly and mounting in this second embodiment are performed in a similar way to that which was described in relation to the first embodiment.

(70) FIG. 13 shows an alternative form of the light emitting diode 9 with its crimping electrical contacts. By comparison with FIG. 11, the electrical contacts 7 are bent up at the start with fold lines 41, so that on assembly, all that is required is for the diode 9 to be placed in its housing and then for the spikes 35 to be lowered in order to crimp the electrical contacts 7 onto the cables 21.

THIRD EMBODIMENT

(71) FIG. 14 shows yet another alternative form of the mounting base 1 which differs from the first or second embodiment in that the mounting base 1 has a mounting groove 43 on its periphery. This alternative form is, for example, very suitable for mounting a module with a mounting base 1 and an associated electrical component 5, on a fabric in the manner of a button, for example for a signaling garment, such as a vest or a parka or even a signaling scarf or a belt.

FOURTH EMBODIMENT

(72) A fourth embodiment of the mounting base 101 is described with reference to FIGS. 15 to 19. Only differences with respect to the first embodiment described with reference to FIGS. 1 to 9 are detailed hereinbelow.

(73) In a similar way to the first embodiment, the mounting base 101 comprises at least one groove 117, and here two grooves 117, respectively having in cross section a portion 119 able to receive an electrical wire 21 and a convergent bottom 125.

(74) Each groove 117 is delimited here by two opposite walls 116 of the mounting base 101. The shape of a groove 117 differs from the first embodiment notably in that the portion 119 able to receive the electrical wire 21 no longer has a cylindrical overall shape of diameter L.sub.MAX. According to the example illustrated, substantially planar opposite walls 116 delimit the portion 119. In this example, the portion 119 is of constant width.

(75) The convergent bottom 125 itself, better visible in FIG. 18, acts as a crimping form when the crimping electrical contact 7 is inserted into the groove 117.

(76) In a similar way to the first embodiment, the convergent bottom 125 comprises two inclined straight slopes 127 which terminate in a straight bottom 129 substantially parallel to the rear face 118 of the mounting base 101. The inclined straight slopes 127 are inclined with respect to the straight bottom 129 of the groove 117 and are inclined in such a way as to converge toward one another at the straight bottom 129.

(77) Of course other converging shapes of convergent bottom 125 may be envisioned.

(78) Referring once again to FIG. 16, according to this fourth embodiment, the or each groove 117 is defined with a non-rectilinear shape, for example a substantially elbowed shape. In this case, the or each groove 117 of the mounting base 101 does not extend along a single rectilinear longitudinal axis 24 as described with reference to the first embodiment of FIGS. 1 to 9.

(79) In this example, the or each groove 117 extends along a substantially elbowed axis and substantially has the overall shape of an L. Thus, the or each groove 117 comprises: a first portion 117.sub.1 near to the housing 103 intended to receive the electrical component 5 extending in a first direction, and a second portion 117.sub.2 distant from the housing 103 extending in a second direction different than the first direction, for example substantially perpendicular to the first direction.

(80) The intersection or elbowed portion between the first portion 117.sub.1 and the second portion 117.sub.2 of the groove 117 is advantageously curved.

(81) According to the example illustrated, in which a mounting base 101 comprises two grooves 117, the first portions 117.sub.1 of the two grooves 117 extend substantially parallel whereas the second portions 117.sub.2 extend in the same direction in opposite senses.

(82) The or each groove 117 therefore has a proximal end 120.sub.1 with respect to the housing 103 and a distal end 120.sub.2, distant from the housing 103, which is not aligned with the proximal end 120.sub.1. The proximal end 120.sub.1 is provided at the level of the first portion 117.sub.1 whereas the distal end 120.sub.2 is provided at the level of the second portion 117.sub.2. More specifically in this example, the proximal end 120.sub.1 and the distal end 120.sub.2 are oriented in two directions substantially perpendicular to one another. The distal end 120.sub.2 allows a suitable electric wire 21 to be inserted into the associated groove 117.

(83) Inserting an electrical wire 21 into a groove 117 along such an elbowed axis of the groove 117, as indicated schematically by the arrow F3 in FIG. 18, allows control over the bending of the electrical wire 21 and avoids the risk of damage to the electrical wire 21 in the face of external stresses once a module comprising a mounting base 101 and an associated electrical component 5 has been assembled and/or is in operation.

(84) Finally, according to this fourth embodiment, the or each groove 117 may comprise an access canal 123 or access passage for the crimping electrical contact 7. This access canal 123 allows the crimping electrical contact 7 to be inserted along an axis F2 substantially perpendicular to the axis of the groove 117, more specifically to the axis of the first groove portion 117.sub.1 near to the housing 103. More generally, the axis F2 of insertion of the crimping electrical contact 7 is substantially perpendicular to the overall plane defined by the mounting base 101.

(85) Moreover, according to the example illustrated, the access canal 123 does not have a width smaller than the maximum width of the portion 119 able to receive the electrical wire 21.

(86) It might be possible, in an alternative form that has not been illustrated, to envision a narrowing that is the opposite to the convergent bottom 125 of the groove 117, so as to form an access canal smaller in width than the portion 119, making it possible when a suitable electrical wire 21, for example having a diameter slightly smaller than the width of the portion 119 but larger than the width of the narrowing that forms the access canal is inserted, for this wire to be guided in the groove 117 without being able to leave this groove.

(87) Moreover, according to the fourth embodiment illustrated in FIGS. 15 to 19, the mounting base 101 is able to no longer exhibit a peripheral edge 31 as described in the first embodiment with reference to FIG. 2. In such a case, an edge 131 (see FIGS. 16 and 19) is provided around the groove or grooves 117 and the housing 103 in order to receive the electrical component 5 rather than on the periphery of the mounting base 101. The edge 131 extends in relief in relation to the overall plane defined by the mounting base 101, more specifically with respect to the plane defined by the rear face 118 of the mounting base 101. The edge 131 therefore extends over a predefined height substantially perpendicular to the plane defined by the rear face 118 of the mounting base 101.

(88) The thickness of such an edge 131 is defined by the person skilled in the art to suit his purposes. As is best visible in FIGS. 16, 17 and 19, the edge 131 may also form a dividing wall 132 between two grooves 117 of the mounting base 101. In the example illustrated, the dividing wall 132 extends between the first portions 117.sub.1 of the grooves 117. It goes without saying that the wall 132 extends in a direction substantially parallel to the grooves 117, here to the first portions 117.sub.1 of the grooves 117. The dividing wall 132 is therefore here produced as one piece with the edge 131. The wall 132 extends in relief in relation to the overall plane defined by the mounting base 101 and more specifically in relation to the plane defined by the rear face 118 of the mounting base 101.

(89) Furthermore, according to the fourth embodiment, the mounting base 101 may have one or more blocking portions 145. This makes it possible to prevent the electrical wire 21 from being pulled out of a groove 117 once mounted. Specifically, the blocking portion or portions is/are able to compress the electrical wire 21 in the associated groove 117.

(90) According to the example illustrated in FIG. 16, the mounting base 101 has a blocking portion 145 at each groove 117. Of course, two blocking portions 145 are conceivable, both at the one same groove 117, for example facing one another.

(91) The or each blocking portion 145 is, for example, as one with the mounting base 101. More specifically, the or each blocking portion 145 is formed as an integral part of the mounting base 101, in this example as an integral part of the edge 131. With more particular reference to the enlarged part of FIG. 16, a blocking portion 145 is formed here by a folded-over section of a wall 116 at the level of the distal end 120.sub.2 of the groove 117. The blocking portion 145 therefore extends from said wall 116 toward the inside of the groove 117. In addition, the blocking portion 145 advantageously extends over a predefined distance allowing it to come into abutment against the electrical wire 21 when the latter is inserted in the associated groove 117, so as to compress the electrical wire 21 between this blocking portion 145 and the wall 116 opposite. The wall 116 opposite may, according to an alternative form that has not been illustrated, exhibit another similar blocking portion 145, and so the electrical wire 21 when inserted would be compressed between two blocking portions 145.

(92) Moreover, such a blocking portion 145 also performs a sealing function, making it possible to limit the potential ingress of liquid such as water.

(93) Of course, provision may be made for the mounting base 101 to have two pairs of grooves 117, in a similar way to the second embodiment described hereinabove.

(94) The mounting base 101 may also receive an electrical component 5 as illustrated in FIGS. 4, 5 or according to the alternative form illustrated in FIG. 11 or even in FIG. 13.

(95) Finally, the mounting base 101 may potentially have a mounting groove in a similar way to the third embodiment.

(96) The method for producing a module 137, such as a lighting module comprising such a mounting base 101 and an electrical component 5 comprising for example a light emitting diode 9, is similar to that of the first embodiment, except that in a first step, by way of nonlimiting example, an electrical wire 21 is passed into each groove 117 in the direction of the arrow F3. Of course, alternatively, the electrical wire 21 could be shaped beforehand to complement the elbowed shape of the groove 117 and be inserted into the groove 117 in the direction of the arrow F2 (namely upward with reference to the layout of FIG. 18). The electrical component 5, in this instance the diode 9, is then inserted for example via the rear face 118 of the mounting base 101 in the direction of the arrow F2. More specifically, the electrical component 5, in this example the diode 9, equipped with its two crimping contacts 7 is inserted with the crimping spikes 35 directed toward the second part of the associated grooves 117 so that on insertion, a crimping onto the electrical wires 21 is achieved.

(97) Likewise, with reference to FIGS. 22 and 23, mounting such a module on a support such as a fabric or garment using an assembly roundel 60 can be done in a similar way to the first embodiment.

FIFTH EMBODIMENT

(98) FIGS. 20 and 21 depict a fifth embodiment of the mounting base 201. Only the differences with respect to the fourth embodiment described with reference to FIGS. 15 to 19 are detailed hereinafter. Elements that are identical are not described again.

(99) As before, the mounting base 201 comprises one or more grooves 217, in this instance two grooves 217. The mounting base 201 further comprises at least one flow guide 247, 249 at the level of at least one groove 217, to make it easier for a layer of encapsulant or resin (not visible in the figures) poured for example on the rear face 218 of the mounting based 201 after the electrical component 5 and the electrical wires 21 have been assembled to spread out even underneath an electrical wire 21 with reference to the layout illustrated in FIG. 21. In order to make FIG. 21 easier to study, just one electrical wire 21 has been depicted.

(100) According to the example illustrated, a flow guide may be produced in the form of a discontinuity 247 between the edge 231 and the wall 232 between two grooves 217. The dimensions of such a discontinuity 247 are defined by the person skilled in the art to suit his purposes. By way of nonlimiting example, this discontinuity 247 is formed here near the intersection, in this instance elbowed intersection, between the first groove portion 217.sub.1 and the second groove portion 217.sub.2. In other words, in this example, the discontinuity 247 is provided near the change in direction of the grooves 217.

(101) Of course, any other siting of the discontinuity 247 may be envisioned to make it easier for the layer of encapsulant or of resin to flow even underneath an electrical wire 21 when the module 237 comprising the mounting base 201, the electrical component 5 and the electrical wire or wires 21 is assembled.

(102) The discontinuity 247 is advantageously sited at a location where, in the mounted state, the electrical wire 21 is most stable, for example at a point where the crimping is most effective.

(103) As an alternative or in addition, a flow guide may be produced in the form of at least one notch 249 provided on the edge 231 at the level of at least one groove 217. Through the creation of such a notch 249, the width of the groove 117 is increased at this point.

(104) The notch or notches 249 may be formed near the first groove portion 217.sub.1 and/or the second groove portion 217.sub.2. In the case of several grooves 217, at least one notch 249 may be provided at the level of each groove 217. In particular, the notch or notches 249 may be made on the edge 231 at the level of the two grooves 217 symmetrically, as illustrated in FIGS. 20 and 21.

(105) Of course, any suitable siting of the notch or notches 249 may be envisioned to facilitate the flow of the layer of encapsulant or resin, even underneath an electrical wire 21 when the module 237 comprising the mounting base 201, the electrical component 5 and the electrical wire or wires 21 is in the assembled state.

(106) In addition, in order to ensure that the layer of encapsulant or resin does indeed pass underneath the electrical wire 21 in the assembled state, a difference in height or difference in level at the bottom of the or each groove 217 may be provided. What is meant by height is the dimension in the direction in which the edge 231 extends in relief with respect to the rear face 218 of the mounting base 201, namely substantially at right angles to the plane defined by the rear face 218 of the mounting base 201. In the example illustrated in FIG. 20, at least one step 251 is provided for this purpose to establish a difference in level with the bottom of the rest of the associated groove 217. The step 251 is therefore higher than the bottom of the rest of the associated groove 217. In other words, the electrical wire 21 when mounted against this step 251, finds itself raised up off the bottom of the rest of the groove 217.

(107) Thus, this difference in level or height in the bottom of the associated groove 217 makes it possible to guarantee that the layer of encapsulant or resin forms a ring around the electrical wire 21, and therefore does indeed pass underneath the electrical wire 21 with reference to the layout illustrated in FIG. 21.

(108) Similarly, a mounting base 1 according to the first, second or third embodiment with reference to FIGS. 1 to 14 may have a flow guide for example in the form of a discontinuity or notch(es) making it easier for the layer of encapsulant or resin to flow and ensuring better distribution thereof.

(109) Of course, the features of the various embodiments described hereinabove may be combined without departing from the scope of the invention.

(110) Moreover, FIGS. 1 to 23 illustrate a mounting base 1; 101; 201 made as a single piece. Of course, it is conceivable to imagine a mounting base made in more than one part, for example in two parts. These two parts are joined together to form a mounting base as described hereinabove.

(111) It will therefore be appreciated that the mounting base 1, 101 according to one or other of the embodiments described hereinabove allows an electrical component 5 to be connected to individual electrical wires 21 easily and without a special-purpose tool.
