The connectors with substrate in the embodiments can be used in all directions.

[0045] The embodiments described below do not limit the inventions according to the claims. Not all of combinations of characteristics explained in the embodiments are essential for the solution of the invention.

First Embodiment

[0046] A configuration of a connector with substrate 10 according to a first embodiment is explained with reference to FIGS. 1 to 13. The connector with substrate 10 according to the first embodiment includes, as shown in FIGS. 1 to 3, a substrate 11 and a compression connector 31 attached to the upper surface of the substrate 11.

[0047] The substrate 11 includes a not-shown printed circuit and the like. The substrate 11 is electrically connected to the compression connector 31 attached to the upper surface of the substrate 11 to be configured to be able to deliver an electric signal, power supply power, and the like.

[0048] A plurality of holes 12 are formed in the substrate 11 as illustrated in, in particular, FIG. 3. A plurality of press-fit pins 37 included in the compression connector 31 explained below are inserted into the plurality of (in the first embodiment, eight) holes 12 to fix the compression connector 31 to the substrate 11. Note that the plurality of press-fit pins 37 are parts formed as the fixing parts according to the present invention.

[0049] The compression connector 31 includes, as shown in FIGS. 7 to 11, contacts 32 that are in contact with the substrate 11, a housing 33 to which the contacts 32 are fixed, a cover shell 34 that covers the upper surface portion of the housing 33, and a bottom shell 35 that covers the lower surface portion of the housing 33.

[0050] As shown in, in particular, FIGS. 8 and 9, a plurality of contacts 32 are disposed to be laterally arranged in the left-right direction.

[0051] Each of the plurality of contacts 32 is fixed to the housing 33 as shown in FIG. 11. A front end portion 32a of the contact 32 curves to be formed in a shape having spring elasticity. That is, when the compression connector 31 is not in contact with the substrate 11, the front end portion 32a of the contact 32 is disposed to project downward from the bottom surface of the bottom shell 35 (a state shown in FIG. 11). Therefore, when the bottom surface of the bottom shell 35 configuring the compression connector 31 is pressed in the ?Z direction against the upper surface of the substrate 11, the front end portions 32a of the plurality of contacts 32 projecting downward from the bottom surface of the bottom shell 35 are pushed into the position of the bottom surface of the bottom shell 35 while applying force by the spring elasticity to the upper surface of the substrate 11. That is, the front end portions 32a of the plurality of contacts 32 receive force in the +Z direction. Therefore, when the compression connector 31 is attached to the substrate 11, since each of the plurality of contacts 32 is pressed against the upper surface of the substrate 11 by the force by the spring elasticity, for example, the not-shown printed circuit and the like disposed on the upper surface of the substrate 11 and the plurality of contacts 32 can maintain a stable and secure connection state.

[0052] On the other hand, a rear end portion 32b of the contact 32 has a linear shape extending straight. As shown in FIG. 11, an electric cable 36 is connected to the rear end portion 32b of the contact 32 by solder or the like. Therefore, an electric signal, power supply power, and the like from the outside are transmitted to the substrate 11 side via the electric cable 36 and the contact 32.

[0053] Note that, concerning the members configuring the compression connector 31 in the first embodiment, the plurality of contacts 32 are made of a conductive metal material and the housing 33 that fixes the plurality of contacts 32 is made of a nonconductive resin material or the like. The cover shell 34 that covers the upper surface portion of the housing 33 and the bottom shell 35 that covers the lower surface portion of the housing 33 are combined, in a state in which the housing 33 is included between the cover shell 34 and the bottom shell 35, in the up-down direction to form an outline shape of the compression connector 31. The cover shell 34 and the bottom shell 35 protect the housing 33, in which the plurality of contacts 32 that receive energization from the electric cable 36 are embedded, by being disposed to enclose the outer circumference of the housing 33 in which the plurality of contacts 32 are embedded. The protection also includes electric and magnetic protection such as an electromagnetic shield in addition to physical protection from an external environment.

[0054] The cover shell 34 configuring the compression connector 31 in the first embodiment includes, as shown in FIG. 12, a top surface 34a disposed in parallel to the substrate 11 and a vertical surface 34b vertically bent in the substrate 11 direction from the top surface 34a of the cover shell 34. Eight press-fit pins 37 as fixing parts piercing through the holes 12 formed in the substrate 11 and functioning as slip-off prevention for the compression connector 31 with respect to the substrate 11 are installed on the substrate 11 side of the vertical surface 34b, that is, the lower side of the vertical surface 34b.

[0055] In the cover shell 34 in the first embodiment, among the eight press-fit pins 37, six press-fit pins 37 are disposed at substantially equal intervals in positions on the front side of the cover shell 34, one press-fit pin 37 is disposed in a position closer to the rear side right end of the cover shell 34, and one press-fit pin 37 is disposed in a position closer to the rear side left end of the cover shell 34.

[0056] Concerning a specific shape of the press-fit pin 37 in the first embodiment, as shown in FIG. 13, the press-fit pin 37 is formed to include a flat base section 37a formed to be connected to the substrate 11 side of the vertical surface 34b, an opening section 37b connected to the substrate 11 side of the base section 37a and including an opening hole 38, and a flat distal end portion 37c formed to be connected to the substrate 11 side of the opening section 37b. In the press-fit pin 37 in the first embodiment, the opening section 37b is formed to have a width dimension larger than the base section 37a and the distal end portion 37c and, further, the width dimension of the opening section 37b is formed in a dimension larger than the inner diameter of the hole 12 formed in the substrate 11. Therefore, when the press-fit pin 37 is inserted into the hole 12 formed in the substrate 11, the wide opening section 37b is located on the inside of the hole 12 of the substrate 11 and the opening section 37b is compressed in the hole 12 of the substrate 11. At this time, force for returning to an original shape acts on the opening section 37b based on the elasticity of a metal material with the wide dimension of the opening section 37b and the action of the opening hole 38. Therefore, a fictional force acts between the opening section 37b of the press-fit pin 37 and the hole 12 of the substrate 11. A sum of the frictional force is force larger than a sum of force by spring elasticity applied to the upper surface of the substrate 11 by each of the plurality of contacts 32. Therefore, the compression connector 31 is held by the frictional force not to slip off in the vertical direction with respect to the substrate 11.

[0057] As explained above, in the connector with substrate 10 according to the first embodiment, the compression connector 31 can be easily connected to the substrate 11 simply by inserting the press-fit pin 37 into the hole 12 formed in the substrate 11. That is, with the connector with substrate 10 according to the first embodiment, a configuration is realized in which, when the compression connector 31 and the substrate 11 are fixed, connector attaching (fixing) work is easy and the compression connector 31 can be fixed to the substrate 11 with a small motion. Therefore, with the connector with substrate 10 according to the first embodiment, it is possible to perform secure attachment while improving workability of attachment (fixing) of the compression connector 31 to the substrate 11.

[0058] A preferred embodiment of the present invention is explained above. However, the technical scope of the present invention is not limited to the scope described in the first embodiment. Various changes or improvements can be added to the first embodiment.

[0059] For example, in the first embodiment explained above, a case in which the eight press-fit pins 37 are used is illustrated. However, the number and disposition positions of the press-fit pins 37 functioning as the fixing parts of the present invention can be optionally changed. For example, the number of the press-fit pins 37 only has to be one or more. The disposition positions of the press-fit pins 37 can be arranged in any positions considering the shapes and the like of the compression connector 31 and the substrate 11.

[0060] For example, in the first embodiment explained above, when the press-fit pin 37 is inserted into the hole 12 formed in the substrate 11, the wide opening section 37b is located on the inside of the hole 12 of the substrate 11 and the opening section 37b is compressed in the hole 12 of the substrate 11. However, in the present invention, the press-fit pin 37 may be used to function as the slip-stop pin. That is, when the press-fit pin 37 is inserted into the hole 12 formed in the substrate 11, the wide opening section 37b may be caught in an inlet on the lower side of the hole 12 to apply slip-off prevention action by allowing the wide opening section 37b to pass the hole 12 of the substrate 11 to pass through the inside of the hole 12 to be located below.

[0061] The configuration of the connector with substrate 10 according to the first embodiment is explained above with reference to FIGS. 1 to 13. Subsequently, a connector with substrate 100 according to a second embodiment, which is another form example that the connector with substrate according to the present invention can take, is explained with reference to FIGS. 14 to 25. Note that, in the following explanation, members that are the same as or similar to the members explained in the first embodiment above are denoted by the same reference numerals and signs and explanation of the members is sometimes omitted.

Second Embodiment

[0062] A configuration of the connector with substrate 100 according to the second embodiment is explained with reference to FIGS. 14 to 25. The connector with substrate 100 according to the second embodiment includes, as shown in FIGS. 14 to 16, the substrate 11, and the compression connector 31 attached to the upper surface of the substrate 11.

[0063] The substrate 11 includes a not-shown printed circuit and the like. The substrate 11 is electrically connected to the compression connector 31 attached to the upper surface of the substrate 11 to be configured to be able to deliver an electric signal, power supply power, and the like.

[0064] The plurality of holes 12 are formed in the substrate 11 as shown in, in particular, FIGS. 17 to 19. A plurality of fixing leg sections 137 included in the compression connector 31 explained below are inserted into the plurality of (in the second embodiment, six) holes 12 to fix the compression connector 31 to the substrate 11. Note that the plurality of fixing leg sections 137 are parts formed as the fixing parts according to the present invention.

[0065] The compression connector 31 includes, as shown in FIGS. 20 to 25, the contact 32 that is in contact with the substrate 11, the housing 33 to which the contact 32 is fixed, the cover shell 34 that covers the upper surface portion of the housing 33, and the bottom shell 35 that covers the lower surface portion of the housing 33.

[0066] As shown in, in particular, FIGS. 21 and 22, the plurality of contacts 32 are disposed to be laterally arranged in the left-right direction.

[0067] Each of the plurality of contacts 32 is fixed to the housing 33 as shown in FIG. 24. The front end portion 32a of the contact 32 curves to be formed in a shape having spring elasticity. That is, when the compression connector 31 is not in contact with the substrate 11, the front end portion 32a of the contact 32 is disposed to project downward from the bottom surface of the bottom shell 35 (a state shown in FIG. 24). Therefore, when the bottom surface of the bottom shell 35 configuring the compression connector 31 is pressed in the ?Z direction against the upper surface of the substrate 11, the front end portions 32a of the plurality of contacts 32 projecting downward from the bottom surface of the bottom shell 35 are pushed into the position of the bottom surface of the bottom shell 35 while applying force by the spring elasticity to the upper surface of the substrate 11. That is, the front end portions 32a of the plurality of contacts 32 receive force in the +Z direction. Therefore, when the compression connector 31 is attached to the substrate 11, since each of the plurality of contacts 32 is pressed against the upper surface of the substrate 11 by the force by the spring elasticity, for example, the not-shown printed circuit and the like disposed on the upper surface of the substrate 11 and the plurality of contacts 32 can maintain a stable and secure connection state.

[0068] On the other hand, the rear end portion 32b of the contact 32 has a linear shape extending straight. As shown in FIG. 24, the electric cable 36 is connected to the rear end portion 32b of the contact 32 by solder or the like. Therefore, an electric signal, power supply power, and the like from the outside are transmitted to the substrate 11 side via the electric cable 36 and the contact 32.

[0069] Note that, concerning the members configuring the compression connector 31 in the second embodiment, the plurality of contacts 32 are made of a conductive metal material and the housing 33 that fixes the plurality of contacts 32 is made of a nonconductive resin material or the like. The cover shell 34 that covers the upper surface portion of the housing 33 and the bottom shell 35 that covers the lower surface portion of the housing 33 are combined, in a state in which the housing 33 is included between the cover shell 34 and the bottom shell 35, in the up-down direction to form an outline shape of the compression connector 31. The cover shell 34 and the bottom shell 35 protect the housing 33, in which the plurality of contacts 32 that receive energization from the electric cable 36 are embedded, by being disposed to enclose the outer circumference of the housing 33 in which the plurality of contacts 32 are embedded. The protection also includes electric and magnetic protection such as an electromagnetic shield in addition to physical protection from an external environment.

[0070] The cover shell 34 configuring the compression connector 31 in the second embodiment includes, as shown in FIGS. 20 to 25, the top surface 34a disposed in parallel to the substrate 11 and the vertical surface 34b vertically bent in the substrate 11 direction from the top surface 34a of the cover shell 34. Six fixing leg sections 137 as fixing parts piercing through the holes 12 formed in the substrate 11 and functioning as slip-off prevention for the compression connector 31 with respect to the substrate 11 are installed on the substrate 11 side of the vertical surface 34b, that is, the lower side of the vertical surface 34b.

[0071] In the cover shell 34 in the second embodiment, among the six fixing leg sections 137, three fixing leg sections 137 are disposed at substantially equal intervals in positions on the front side of the cover shell 34 and three fixing leg sections 137 are disposed at substantially equal intervals in positions on the rear side of the cover shell 34. In the second embodiment, the fixing leg sections 137 disposed on the front side and the fixing leg sections 137 disposed on the rear side are respectively disposed to overlap in a front view. Two fixing leg sections 137 in the front and the rear are paired to form three sets of pairs of the fixing leg sections 137 in total.

[0072] Concerning a specific shape of the fixing leg section 137 in the second embodiment, as shown in FIGS. 20 to 25, the fixing leg section 137 is formed to include a flat base section 137a formed to be connected to the substrate 11 side of the vertical surface 34b, an opening section 137b connected to the substrate 11 side of the base section 137a and including an opening hole 138, and a flat distal end portion 137c formed to be connected to the substrate 11 side of the opening section 137b. In the connector with substrate 100 in the second embodiment, a slip-stop pin 140 that can be inserted into the opening hole 138 of the opening section 137b formed in the fixing leg section 137 is prepared.

[0073] The slip-stop pin 140 in the second embodiment includes, as shown in FIGS. 17 to 19, a pin distal end portion 140a that is bent when being inserted into the opening hole 138, an insertion section 140b that is inserted into the opening hole 138 to function as slip-off prevention for the compression connector 31 with respect to the substrate 11, and a flange section 140c having a width dimension larger than the hole diameter of the opening hole 138. Note that, in FIGS. 16 to 19 and 25, a state in which the pin distal end portion 140a is already bent is drawn. However, the pin distal end portion 140a of the slip-stop pin 140 at a stage before installation has a shape extending straight in the front-rear direction like the insertion section 140b.

[0074] Subsequently, an installation method for the connector with substrate 100 according to the second embodiment is explained. First, the fixing leg sections 137 included in the compression connector 31 are inserted into the holes 12 of the substrate 11 from a state shown in FIGS. 17 to 19. From this state, three slip-stop pins 140 are inserted into the opening holes 138 formed in the opening sections 137b included in the fixing leg sections 137. Note that, as explained above, as the six fixing leg sections 137 included in the compression connector 31 in the second embodiment, the fixing leg sections 137 disposed on the front side and the fixing leg sections 137 disposed on the rear side respectively form the three sets of the pairs of the fixing leg sections 137 in total to overlap in the front view. Therefore, concerning the opening holes 138 formed in the opening sections 137b included in the six fixing leg sections 137, three sets of pairs of two opening holes 138 are present. The three slip-stop pins 140 are respectively inserted into the three sets of the paired opening holes 138. At this time, the slip-stop pin 140 is inserted into the opening hole 138 with the distal end portion 137c directed from the rear side to the front side. When the slip-stop pin 140 is inserted until the flange section 140c of the slip-stop pin 140 comes into contact with the opening hole 138 of the fixing leg section 137 disposed on the rear side, as shown in FIG. 25, the insertion section 140b of the slip-stop pin 140 is laid between one set of the opening holes 138 disposed to overlap in the front view. Further, the pin distal end portion 140a of the slip-stop pin 140 pierces forward through the opening hole 138 of the opening section 137b formed in the fixing leg section 137 on the front side. The pin distal end portion 140a of the slip-stop pin 140 is bent downward in this state to complete an installation state shown in FIG. 25.

[0075] When the installation state shown in FIG. 25 is completed, forces in directions separating from each other act between the substrate 11 and the compression connector 31 with force by spring elasticity applied to the upper surface of the substrate 11 by each of the plurality of contacts 32. However, since the slip-stop pins 140 are installed in the fixing leg sections 137 included in the compression connector 31 to sandwich the substrate 11, the slip-stop pin 140 receives the force by the spring elasticity to hold the compression connector 31 not to slip off in the vertical direction with respect to the substrate 11.

[0076] As explained above, in the connector with substrate 100 according to the second embodiment, the compression connector 31 can be easily connected to the substrate 11 simply by inserting the fixing leg section 137 into the hole 12 formed in the substrate 11 and further inserting the slip-stop pin 140 into and fixing the slip-stop pin 140 in the opening hole 138 formed in the fixing leg section 137. The slip-stop pin 140 in the second embodiment is prevented from slipping off by bending the pin distal end portion 140a after being inserted into the opening hole 138 included in the opening section 137b of the fixing leg section 137. Therefore, the slip-stop pin 140 is not dropped or lost unlike the screws and the nuts of the related art. Further, since the connector with substrate 100 contains a mechanism for fixing the compression connector 31 with a pin shape of the slip-stop pin 140, unlike with the related art, work manhours involving attachment are reduced and torque management for the screws is unnecessary.

[0077] That is, with the connector with substrate 100 according to the second embodiment, a configuration is realized in which, when the compression connector 31 and the substrate 11 are fixed, connector attaching (fixing) work is easy and the compression connector 31 can be fixed to the substrate 11 with a small motion. Therefore, with the connector with substrate 100 according to the second embodiment, it is possible to perform secure attachment while improving workability of attachment (fixing) of the compression connector 31 to the substrate 11.

[0078] A preferred embodiment of the present invention is explained above. However, the technical scope of the present invention is not limited to the scope described in the second embodiment. Various changes or improvements can be added to the second embodiment.

[0079] For example, in the second embodiment explained above, a configuration is adopted in which, concerning the opening holes 138 formed in the opening sections 137b included in the six fixing leg sections 137, the three sets of the pairs of the two opening holes 138 are prepared and the three slip-stop pins 140 are respectively inserted through the present three sets of the pairs of the opening holes 138. However, a method of respectively combining the numbers and the disposition positions of the fixing leg sections 137 and the slip-stop pins 140 functioning as the fixing parts of the present invention can be optionally changed.

[0080] It is evident from the description of the claims that such changed or improved forms can also be included in the technical scope of the present invention.
