Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and in particular relates to a waterproof camera connector. Background Technology

[0002] Existing automotive camera connectors typically consist of wire-end connectors and board-end connectors. The board-end connectors are soldered onto a PCB board, while one end of the wire-end connector connects to a mating terminal on the circuit board for conductive connection, and the other end mates with an external automotive coaxial cable to achieve electrical connection, thereby receiving data from the automotive camera or controlling the camera. Waterproofing of existing automotive camera connectors relies on a large amount of AB glue to encapsulate the wire, back shell, and metal housing. However, the sealing between the metal housing and the wire requires a large amount of glue during the bonding process, which is difficult to cure and requires a significant amount of time for the glue to set and cure, resulting in high production costs and an unstable manufacturing process. Utility Model Content

[0003] Based on the above-mentioned technical problems, this application proposes a waterproof camera connector to solve the technical problems of poor adhesive application and poor waterproof performance of camera connectors.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] It should be noted that in this embodiment, the direction of the first center needle relative to the center line is defined as front, front end, front side, and front, and the opposite direction is defined as back, back end, back side, and rear.

[0024] like Figures 1 to 3 As shown, this embodiment of the utility model provides a waterproof camera connector, including a metal housing 10, a cable assembly 20, and a rear housing 30. Specifically:

[0025] The metal housing 10 includes a receiving cavity 101 and a connecting hole 102 that communicates with the receiving cavity 101 and protrudes rearward; the rear housing 30 is integrally injection molded at the rear end of the connecting hole 102 and is used to fix and clamp the cable assembly 20.

[0026] like Figure 5As shown, in a preferred embodiment, the cable assembly 20 includes a center wire 207, a center pin 206, a floating head 201, a first outer conductor 202, and a second outer conductor 203. The front end of the center line 207 is stripped to expose the shielding layer 2070. A copper tube 212 is riveted to the outside of the shielding layer 2070. The two sides of the copper tube 212 are injection molded with liquid silicone to form sealing bodies, specifically the first sealing body 211 between the copper tube 212 and the second outer conductor 203, and the second sealing body 213 between the copper tube 212 and the center line 207. Sealing at both ends of the copper tube can further play a waterproof role. The center pin 206 is coaxially riveted to the protruding end of the center line 207 for insertion with the board end connector 40. The board end connector 40 includes a PCB board 401 and a plug 402. The floating head 201 is sleeved with the first outer conductor 202, and the rear end of the first outer conductor 202 is sleeved with the second outer conductor 203. The first outer conductor 202 and the second outer conductor 203 are inserted through the hole 102. The floating head 201 is used to insert with the board end connector 10 soldered and fixed on the PCB board 9. The first outer conductor 202 and the second outer conductor 203 are integral zinc die-cast components manufactured by die casting. As the outer conductors of the coaxial connector, they provide effective electromagnetic shielding for internal signal transmission. A sealing ring 204 is fitted around the second outer conductor 203, positioned between the second outer conductor 203 and the connector hole 102.

[0027] As a preferred embodiment, a stepped fixing groove 1020 is provided on the outer surface of the connector hole 102 of the metal shell 10. The edge of the rear shell 30 overlaps the outside of the fixing groove 1020, and is then integrally injection molded and fixed layer by layer. This can improve the overall waterproof performance and sealing performance of the connector, and reduce the number of times glue is applied, thus reducing costs.

[0028] In a preferred embodiment, the front end of the second outer conductor 203 is provided with a first groove 2030, and the sealing ring 204 is disposed within the first groove 2030. The outer surface of the rear end of the second outer conductor 203 is also provided with two second grooves 2031. The rear shell 30 and the second grooves 2031 are fixed layer by layer by an integral injection molding process. By setting multiple grooves to overlap with the rear shell 30 and form a stepped structure, and then fixing it by thermoplastic process, the overall connection strength of the connector can be strengthened and the sealing performance can be improved.

[0029] like Figure 5As shown, the center pin includes a first center pin 2060 and a second center pin 2061 that are inserted front to back. The first center pin 2060 is located inside the floating head 201, and a front insulator 205 is provided between the first center pin 2060 and the floating head 201. The second center pin 2061 is riveted to the front end of the center line 207. An inner conductor 210 is provided on the outside of the second center pin 2061, an inner insulator 208 is provided between the second center pin 2061 and the inner conductor 210, and an outer insulator 209 is provided between the inner conductor 210 and the second outer conductor 203. The front insulator 205, the inner insulator 208, and the outer insulator 209 are all fixed by riveting and dotting, providing reliable mechanical support for the center pin inside, helping to fix the relative position of the inner conductor 210 and the second outer conductor 203, while also providing electrical insulation.

[0030] To improve the waterproof sealing of the connector, as a preferred embodiment, the edge at the connection between the inner insulator 208 and the second center pin 2061 can be sealed with adhesive (not shown in the figure).

[0031] Reference Figures 4-5 As a preferred embodiment, several fixing points 1021 can also be provided on the edge around the connection hole 102 of the metal shell 10. After the cable assembly 20 is installed and the second outer conductor 203 is fixed with the metal shell 10 by interference fit, several fixing blocks 214 are used to mark the fixing surface 2032 exposed from the connection hole 102 of the second outer conductor 203 to further increase the connection stability.

[0032] Based on the above-mentioned waterproof camera connector, its assembly process is as follows:

[0033] First, the floating head 201 needs to be assembled into the first outer conductor 202. The copper tube 212 is passed through the center line 207. Then, the two center pins, after being inserted, are riveted together with the front end of the center line 207. Next, the outer insulator 209 is assembled into the second outer conductor 203, the front insulator 205 is assembled between the first center pin 2060 and the center line 207, and the inner insulator 208 is assembled between the second center pin 2061 and the inner conductor 210. Then, the center line 207, which is used to rivet the center pins, is passed through the assembled second outer conductor 203. Finally, the copper tube 212 is riveted onto the second outer conductor 203. 3. Subsequently, adhesive is applied to both sides of the riveted copper tube 212 for initial sealing (forming a first sealing body 211 and a second sealing body 213). Simultaneously, adhesive is applied to the inner and outer sides of the inner insulator 208 to seal around the inner insulator 208 and the second center pin 2061. Then, the assembled first outer conductor 202 is riveted into the second outer conductor 203, and the sealing ring 204 is assembled onto the second outer conductor 203. The assembled cable assembly 20 is then riveted and fixed to the metal shell 10. Finally, the metal shell 10, the back shell 30, and the cable assembly 20 are sealed and connected by molding. This process achieves waterproof performance through a single molding step, improving the stability of the product manufacturing process and waterproof performance.
