SPECIFIC EMBODIMENTS

[0030] Embodiments of the present application will be described exemplarily below. As those skilled in the art should realize, the embodiments explained may be amended in various ways without departing from the concept of the present application. Thus, the accompanying drawings and the description are in essence demonstrative and non-limiting. In the following text, identical drawing reference labels generally indicate functionally identical or similar elements.

[0031] FIG. 1 schematically shows a bridging connector 100 according to an embodiment, which is used to connect the circuit board components 200, especially for mechanical and electrical coupling of the circuit board components 200. Before being connected by the bridging connector 100, the circuit board components 200 may have a predetermined position and orientation with respect to each other. It should be noted that although the drawings show the connection of only two circuit board components 200 through one bridging connector 100, it is also possible to connect more than two, for example, three, four, or more, circuit board components through one bridging connector 100.

[0032] The proposed bridging connector 100 has a housing 101 formed of a dielectric material, for example, by injection molding, and contact bodies 120 made of a conductive material that are accommodated in the housing 101 (see FIG. 4). The dielectric material may be selected from PA66, PA46, PBT, PA6T, PAST, PPS, LCP or other suitable materials, for example, and the conductive material may be selected from brass, phosphor bronze or other suitable materials, for example. If necessary, a contact body may be gold-plated or tin-plated or be subjected to another suitable treatment. Exemplarily, the housing 101 has a rigid structure or a flexible structure. A plurality of contact bodies 120 may be accommodated in the housing 101, and, as they are arranged side by side, they may also be referred to as pin headers.

[0033] As may be seen from FIG. 1, the housing 101 has four guide holes 102, referred to as 102A, 102B, 102C, and 102D, respectively, for a clearer explanation, and arranged on both sides of the housing 101 accordingly, which means that two guide holes are provided on each side. In the example shown, one of the two guide holes on each side is a round hole and the other is an elliptical hole. Certainly, a specific shape of each guide hole may be set as required.

[0034] The contact bodies 120 are centrally arranged in the housing 101. In the example shown, a recess 105 is formed in the section of the housing 101 for the contact bodies 120, and thus two opposite wall portions 106 are formed in the housing. The two ends of a contact body 120 protrude from the bottom of the recess 105.

[0035] In the example shown, the surface of the side from which the contact bodies 120 of the housing protrude consists of two surfaces 107, 108 (see FIG. 3), and they are inclined with respect to the horizontal plane H. As may be seen from the simplified drawing on the right of FIG. 3, the surface 107 on the right forms an angle with the horizontal plane H. The surfaces 107 and 108 may be arranged symmetrically to each other, so that they form the same angle with the horizontal plane H. In an example not shown, the surfaces 107 and 108 may respectively form different angles with respect to the horizontal plane.

[0036] An exemplary embodiment of the guide holes is shown in FIG. 3. The shown guide holes 102A and 102C, instead of being cylindrical holes with a constant cross-section in the longitudinal extension direction, may each be regarded as being formed by splicing two horn-shaped openings, wherein the large opening sides of the horn-shaped openings are on both sides of the guide hole. Therefore, the inner walls 103A and 103C of a guide hole first gradually become smaller and then gradually become larger in the longitudinal extension direction. This is particularly beneficial to guiding the provided guide pins into the guide holes.

[0037] FIG. 4 shows a three-dimensional view of a contact body 120, which is substantially U-shaped. The contact body 120 has a connecting portion 122 and terminals 121 on both sides of the connecting portion 122. The connecting portion 122 is completely enclosed in the housing 101. The terminal 121 is, for the most part, exposed from the housing 101, that is, protruding from the housing 101 in a cantilever manner, which makes the terminal 121 movable to a certain extent to compensate for the tolerance between the electrical contact holes of the circuit board component. The terminals 121 arranged on both sides should be respectively perpendicular to the contact surfaces 107 and 108 on the corresponding side. Therefore, as may be seen from the drawing on the right of FIG. 3, the terminal 121 forms an angle with respect to the vertical plane V, wherein the angle is equal to the angle , which means that an angle formed by the terminal on the corresponding side and the vertical plane is equal to an angle between the bottom surface of the corresponding side of the housing and the horizontal plane.

[0038] In the example shown, the top section of the terminal 121 is in the shape of a needle eye and is tapered, which makes the top section elastically deformable. A distance between the outer side surfaces of the top section of the terminal 121 on both sides of the needle eye is greater than the diameter of the electrical contact holes 202 into which a circuit board component is to be inserted. Therefore, after insertion into the electrical contact holes 202, reliable contact between the top section of the terminal 121 and an electrical contact hole 202 may be achieved.

[0039] In the example shown in FIG. 11, a groove 1061 is provided on a wall portion 106 of the connector 100. The depth of the groove 1061 is smaller than or equal to the height of the wall portion 106. In the example shown in FIG. 11, the groove 1061 is provided in a middle position of the wall portion 106, and the depth of the groove 1061 is smaller than the height of the wall portion 106. However, in another example, a position of provision of and width of the groove 1061 may be adjusted as required, and the groove 1061 may also have a depth equal to the height of the wall portion 106, that is, penetrating the wall portion 106, which is not specifically limited in the present application. The provision of the groove 1061 can provide further convenience in adjusting an angle between the contact surfaces 107 and 108 of the connector 100 according to different arrangements of a circuit board component 200 to match the board surface 205 of the circuit board component 200.

[0040] FIG. 5 shows a connection assembly 400 according to an embodiment, which comprises a carrier 300 as well as circuit board components 200 and the above-described bridging connector 100 that are arranged on the carrier 300. As shown in the figure, the circuit board components 200 are linearly arranged on the carrier 300.

[0041] The carrier 300 has guide pins 302, 303 and hooks 304 for the circuit board components 200, and is provided with bosses 305 for the circuit board components 200 (see FIG. 6), the hooks 304 being elastically deformable, wherein the guide pins 302, 303 are used to limit the position of the circuit board components 200 in the lateral direction, and the hooks 304 and the bosses 305 are used to, in conjunction, limit the position of the circuit board components 200 in the vertical direction. For this purpose, a circuit board component 200 is provided with perforations 201 and 203 for guide pins 302 and 303, and perforations 204 for the hooks 304. The bosses 305 support a circuit board component 200 on one side, and the hooks 304 are hooked on the other side of the circuit board component 200.

[0042] In an embodiment that is not shown herein, a circuit board component 200 may also be fixed on the carrier 300 with screw members and, therefore, at least the hooks may be eliminated and the corresponding screw holes may be provided in the carrier 300. Certainly, other methods of fixation are also feasible.

[0043] The guide pins 303 of the carrier 300 are also used to be received in corresponding guide holes of the bridging connector 100, as may be seen in FIGS. 7 to 10. The peripheral side of each guide pin 303 is in contact with the narrowest part of the inner wall of the guide hole, thereby allowing the positioning of the bridging connector 100 with respect to the printed circuit board components to be connected, especially the electrical contact holes 202 thereof.

[0044] FIGS. 8 to 10 show cross-sectional views of the connected connection assembly 400. It is clear that the surfaces 107 and 108 on the lower side of the bridging connector respectively abut on the surface 205 of the connected printed circuit board component 200, and that the tips 124 of the terminals 121 protrude from one side of the printed circuit board component 200. The inner walls 103B, 103D of the guide holes 102B, 102D are provided in the same manner as the other guide holes.

[0045] The connection assembly shown may be used for vehicle lamps. To this end, the carrier 300 may be a reflective component that has linearly arranged reflector elements 301 according to the arrangement of a circuit board component. Therefore, the circuit board component may have a light source, for example, a semiconductor light source; the reflector element 301 has an opening for a light source and is provided with a reflecting plane 307. Preferably, the connection assembly shown is used for vehicle tail lights, in particular penetrative tail lights.

[0046] The present application, instead of being limited to the above-described structures, may also have other variants. Although the present application has already been described by means of a limited number of embodiments, those skilled in the art could, drawing benefit from this disclosure, design other embodiments which do not depart from the scope of protection of the present application disclosed herein. Thus, the scope of protection of the present application should be defined by the attached claims alone.
