[0049] In view of the technical problems existing in the prior art, the basic concept of this utility model is to set welding pins on the conductive sheet of the contact element that can be soldered and fixed to the printed circuit board, thereby replacing the method of connecting wires and solving a series of problems existing in the wiring method.

[0050] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0051] Embodiment 1 of the connector in this utility model:

[0052] like Figure 3 As shown, the connector includes a housing 5 and contacts mounted on the housing 5. The contacts include a conductive sheet 6 and an outer sheath 7. (The last sentence appears to be incomplete and possibly refers to a different connector.) Figure 4 and Figure 5 As shown, the conductive sheet 6 includes a contact portion 6-1, a soldering pin 6-2, and a transition portion 6-3. The contact portion 6-1 is located at one end of the conductive sheet 6, and the soldering pin 6-2 is located at the other end of the conductive sheet 6. The contact portion 6-1 is used to connect with the contacts of the adapter connector to achieve current transmission. The transition portion 6-3 connects the contact portion 6-1 and the soldering pin 6-2. The transition portion 6-3 is provided with a limiting structure for limiting the outer sheath 7. Specifically, limiting plates 6-3-3 are vertically connected to both sides of the transition portion 6-3 near the contact portion 6-1, and each limiting plate 6-3-3 is provided with a limiting groove 6-3-4.

[0053] like Figure 6As shown, the outer sheath 7 includes a sleeve body 7-1, which is formed by bending a sheet metal and riveting it together, thus forming a riveting line 7-5. The sleeve body 7-1 is provided with two first limiting arms 7-2, each of which is used to engage with a corresponding limiting groove 6-3-4 to prevent the outer sheath 7 from detaching from the conductive sheet 6. When assembling the outer sheath 7 with the conductive sheet 6, the sheet metal is bent and fitted onto the outside of the transition portion 6-3, with both ends of the sheet metal fixed by riveting to form the sleeve body 7-1. During the bending process, the first limiting arms 7-2 engage with the corresponding limiting grooves 6-3-4.

[0054] In addition, a second limiting arm 7-4 is provided at the end of the sleeve 7-1. The second limiting arm 7-4 can stop against the side wall of the groove at the root of the limiting plate 6-3-3, further enhancing the anti-detachment effect.

[0055] In addition, pawls 7-3 are provided on both sides of the sleeve 7-1, combined with Figure 3 As shown, when the contact is installed into the housing 5, the spring claws 7-3 open after assembly and engage with the step inside the housing 5 to prevent the contact from coming out. Simultaneously, the spring claws 7-3 on both sides can be repositioned using tooling to remove and unload the contact.

[0056] The soldering pin 6-2 is used for soldering and fixing to the printed circuit board, thus eliminating the need for wiring operations. Therefore, no extra space is required for wire bending, which matches the layout requirements of highly integrated vehicle spaces. Simultaneously, the conductive sheet 6 can be directly soldered to the printed circuit board, eliminating the steps of crimping copper tube terminals to the wire ends and crimping or soldering to contacts, reducing turnover, simplifying the process, improving manufacturing efficiency, facilitating automated soldering and assembly, and reducing costs. Furthermore, it can improve product standardization and reduce investment.

[0057] like Figure 4 and Figure 5 As shown, the transition portion 6-3 in this embodiment is generally L-shaped. The transition portion 6-3 includes a first transition body 6-3-1 and a second transition body 6-3-2 arranged vertically. The length of the first transition body 6-3-1 is greater than the length of the second transition body 6-3-2. The first transition body 6-3-1 is connected to the contact portion 6-1, and a limiting plate 6-3-3 is disposed on the first transition body 6-3-1. The second transition body 6-3-2 is connected to the welding pin 6-2. The extension direction of the welding pin 6-2 is perpendicular to the mating direction of the contact portion 6-1. This arrangement achieves a 90-degree rotation, meeting the requirements of specific assembly and mating angles.

[0058] Meanwhile, in this embodiment, the transition part 6-3 is a flat plate structure, the contact part 6-1 is also a flat plate structure, and the welding pins 6-2 are set to three. The transition part 6-3, the contact part 6-1, and the welding pins 6-2 are integrally connected by a plate. The thickness directions of the first transition body 6-3-1 and the second transition body 6-3-2 are the same, and the thickness directions of the first transition body 6-3-1 and the second transition body 6-3-2 are both perpendicular to the extension direction of the welding pins 6-2 and the insertion direction of the contact part 6-1. In this way, the prototype of the conductive sheet 6 can be obtained by punching the plate, and then the two limiting plates 6-3-3 can be bent, which is relatively convenient to manufacture.

[0059] Embodiment 2 of the connector in this utility model:

[0060] The difference between this embodiment and Embodiment 1 lies in the structure of the conductive sheet, such as... Figure 7 As shown, although the transition section is still L-shaped as a whole, it still includes a first transition body 6-3-1 and a second transition body 6-3-2 arranged vertically. The length of the first transition body 6-3-1 is still greater than the length of the second transition body 6-3-2. The first transition body 6-3-1 is still connected to the contact part 6-1. The limiting plate 6-3-3 is still set on the first transition body 6-3-1. The second transition body 6-3-2 is still connected to the welding pin 6-2. The extension direction of the welding pin 6-2 is still perpendicular to the insertion direction of the contact part 6-1. However, the difference is that the transition section is a bent plate structure. There is a bent part 6-3-5 between the first transition body 6-3-1 and the second transition body 6-3-2. The thickness directions of the first transition body 6-3-1 and the second transition body 6-3-2 are perpendicular, thereby satisfying another assembly and insertion requirement.

[0061] Embodiment 3 of the connector in this utility model:

[0062] like Figure 8 As shown, the difference between this embodiment and embodiment 2 is that the transition part is a bent and twisted plate structure. Although there is still a bent part 6-3-5 between the first transition body 6-3-1 and the second transition body 6-3-2, there is also a twisted part 6-3-6 on the first transition body 6-3-1. That is, the transition part has both bending and twisting. However, the thickness direction of the first transition body 6-3-1 and the second transition body 6-3-2 is still perpendicular, thereby satisfying another kind of assembly and insertion requirement.

[0063] Embodiment 4 of the connector in this utility model:

[0064] like Figure 9As shown, the difference between this embodiment and Embodiment 1 is that the conductive sheet includes a first sheet 6' and a second sheet 6" with the ends of the first sheet 6' and the second sheet 6" stacked and fixed. The specific fixing method can be welding, riveting, or bolting. The first sheet 6' is provided with a contact portion 6-1, and the outer sheath 7 is limited on the first sheet 6', that is, the limiting plate is provided on the first sheet 6'. The second sheet 6" is provided with a welding pin 6-2. The part of the second sheet 6" except for the welding pin 6-2 is L-shaped. A part of the first sheet 6' and a part of the second sheet 6" together constitute a first transition body, and a part of the second sheet 6" constitutes a second transition body, so that the entire transition part is still L-shaped.

[0065] The advantage of using a split design for the conductive sheet is that the first sheet 6' and its upper limit outer sheath 7 can serve as a standard part, improving product standardization, while the second sheet 6" can take various forms to meet customized needs and achieve product diversification.

[0066] Embodiment 5 of the connector in this utility model:

[0067] like Figure 10 As shown, unlike the above embodiments, the transition part 6-3 is a single piece and has an overall "I"-shaped structure. The extension direction of the welding pin 6-2 is opposite to the insertion direction of the contact part 6-1, thereby satisfying another assembly and insertion requirement.

[0068] Embodiment 6 of the connector in this utility model:

[0069] Unlike Embodiment 4, the portion of the first sheet excluding the contact portion is L-shaped. In this case, a portion of the first sheet and a portion of the second sheet together constitute the second transition body, and a portion of the first sheet constitutes the first transition body.

[0070] Embodiment 7 of the connector in this utility model:

[0071] Unlike Embodiments 4 and 6, the outer sheath is positioned on the second piece, and the limiting plate is disposed on the second piece. Of course, in other embodiments, the outer sheath can also be positioned on the stacked portion of the first and second pieces, in which case the limiting plate is disposed on either the first or the second piece.

[0072] Embodiment 8 of the connector in this utility model:

[0073] Unlike Embodiment 3, the torsion portion is located on the second transition body.

[0074] In other embodiments of the connector: Unlike any of the embodiments above, the transition portion can also be Z-shaped, that is, an additional vertically connected transition body on the basis of an L-shape.

[0075] In other embodiments of the connector: Unlike any of the above embodiments, the limiting structure on the transition portion for limiting the outer sheath can be a narrowed section. In this case, the limiting plate is no longer vertically connected to the transition portion; instead, the transition portion is locally narrowed to form a narrowed section. Limiting arms are then provided at both ends of the outer sheath, and the sidewalls at both ends of the narrowed section can stop against the limiting arms, preventing the outer sheath from coming off. Of course, in other embodiments, the limiting structure can also be a protrusion, which is used to press against the outer sheath to fix it in place.

[0076] In summary, the contact element in this connector features a built-in positioning structure, simplifying assembly and enabling contact element removal and removal, reducing wiring and turnover, and improving efficiency. It also allows for soldering to the printed circuit board on the device side, achieving automated assembly. Furthermore, it enhances product standardization and reduces investment. In addition, the versatile tail design can meet diverse needs.

[0077] The embodiment of the contact element in this utility model is as follows: the specific structure of the contact element is the same as that of the contact element in any of the above-described connector embodiments, and will not be repeated here.

[0078] The embodiment of the conductive sheet of the contact element in this utility model is as follows: the specific structure of the conductive sheet of the contact element is the same as that of the conductive sheet in any embodiment of the connector described above, and will not be repeated here.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
