Description

Technical Field

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

[0002] Currently, most cars are equipped with in-vehicle cameras. In-vehicle cameras are image acquisition devices installed in cars to monitor the surrounding environment, offering advantages such as convenient reversing, driving recording, and real-time observation of the vehicle's interior and exterior. Existing in-vehicle camera connectors typically consist of wire-end connectors and board-end connectors. The board-end connector is soldered onto the 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 connects to an external vehicle coaxial cable for electrical connection, thereby receiving data from the in-vehicle camera or controlling the in-vehicle camera.

[0003] In practical applications, due to various complex operating conditions such as vibration and assembly errors, the wire-end connector and the board-end connector may experience axial or radial positional misalignment during mating. Continuing to insert them under these conditions can easily damage the conductors at the mating interface, affecting signal transmission. Furthermore, with the advancement of lens technology, higher requirements are being placed on the allowable misalignment. Since board-end connectors are typically soldered directly onto the PCB, it is necessary to design a wire-end connector that can automatically correct for positional misalignment to ensure a reliable connection between the wire-end connector and the board-end connector. Utility Model Content

[0004] The purpose of this invention is to design a coaxial cable direct-insertion camera connector to solve the problems of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coaxial through-hole camera connector includes an outer housing and a cable assembly. The outer housing includes a back cover with a panel cavity shape and a connector communicating with the panel cavity. The cable assembly includes a coaxial cable with a shielding layer and a center wire stripped to expose one end. A center terminal is riveted to the center wire. An outer conductor is riveted to the shielding layer. An insulating medium is provided between the outer conductor and the center terminal. The outer conductor is inserted through the connector. A floating spring is provided in the floating space between the outer conductor and the inner wall of the connector. A back cover for clamping and fixing the coaxial cable is coaxially sleeved on the outer end of the connector.

[0007] Furthermore, the outer conductor includes a fixing portion riveted to the shielding layer and a mating sleeve portion extending toward the center terminal for mating with the board-end connector.

[0008] Furthermore, the outer wall of the fixing part is formed by a rubber-coating injection molding process to form a wire harness with a sealing groove.

[0009] Furthermore, a sealing ring is injection molded from liquid silicone within the sealing groove.

[0010] Furthermore, the outer wall of the docking cylinder is formed with an outwardly protruding anti-reverse platform, and the inner wall of the joint is provided with a ring of limiting protrusions.

[0011] Furthermore, the floating snap ring includes a cylindrical snap ring body and a floating spring arm that is bent inward from the side wall portion of the snap ring body and elastically abuts against the outer conductor.

[0012] Furthermore, one end of the snap ring body abuts against the limiting protrusion, and the other end is riveted and fixed to the inner end face of the connector.

[0013] Furthermore, the outer conductor is fixed to the insulating medium by riveting and marking.

[0014] Furthermore, the outer wall of the connector is formed with barbs, and the back cover is provided with a snap hole that matches the barbs, so that the back cover is snapped and fixed to the connector.

[0015] Compared with the prior art, the beneficial technical effects of the coaxial direct-insertion camera connector provided by this utility model are as follows:

[0016] 1. By adopting a wire harness encapsulation design, the outer conductor, coaxial cable, and sealing ring are formed into a whole, which simplifies the assembly process, improves assembly efficiency, and effectively enhances the waterproof sealing performance of the connector.

[0017] 2. By setting a floating retaining ring between the outer conductor and the outer housing, it can serve as the main force-providing unit to bear the backward movement of the wire harness, while also allowing the wire harness to swing in a certain space to effectively compensate for the gap and deviation between the plug connector and the socket connector, making the contact tighter and more reliable, reducing link loss, and improving the stability of the connector.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] This utility model embodiment provides a coaxial cable direct-insertion camera connector, including an outer housing 1, a cable assembly, a floating retaining spring 7, and a rear cover 8. Specifically:

[0029] like Figures 1 to 3 As shown, in this embodiment, the outer housing 1 includes a rear housing 101 with a panel cavity shape and a connector 102 communicating with the panel cavity; the outer housing 1 includes a rear housing 101 with a panel cavity shape and a connector 102 with a mating cavity, the connector 102 is integrally die-cast with the rear housing 101, and the mating cavity is communicating with the panel cavity.

[0030] like Figures 1 to 5 As shown in the preferred embodiment, the cable assembly includes a coaxial cable 2, a center terminal 3, an insulating medium 11, and an outer conductor 4. One end of the coaxial cable 2 is stripped to expose a shielding layer 201 and a center wire 202. The center terminal 3 is coaxially riveted to the extended end of the center wire 202 for insertion into the board-end connector 10. A ring clamp 203 is also riveted to the shielding layer 201 to provide additional mechanical support and stability, ensuring that the shielding layer 201 maintains the correct position and shape during subsequent riveting. The outer conductor 4 is a one-piece zinc die-cast component manufactured by die casting. As the outer conductor of the coaxial connector, it provides effective electromagnetic shielding for internal signal transmission. The outer conductor 4 includes a fixing part 401 riveted to the clamp 203 and a mating sleeve part 402 extending towards the center terminal 3. The mating sleeve part 402 is used for mating with the board-end connector 10 soldered to the PCB board 9. The insulating medium 11 is disposed between the inner wall of the docking cylinder 402 and the center terminal 3, and is fixed to the docking cylinder 402 by riveting and dotting. It provides reliable mechanical support for the center terminal 3, helps to fix the relative position of the inner conductor and the outer conductor 4, and plays the role of electrical insulation.

[0031] like Figure 3 and Figure 4 As shown, to improve the waterproof sealing of the connector, in a preferred embodiment, an annular baffle 403 is provided on the outer wall of the fixing part 401 and the mating cylinder part 402. The outer wall of the fixing part 401 is formed with a wire harness coating 5 having a sealing groove 501 by a rubber injection molding process. A sealing ring 6 is formed by liquid silicone injection molding inside the sealing groove 501, so that the outer conductor 4, the coaxial cable 2 and the sealing ring 6 are formed into a whole, simplifying the assembly process and improving assembly efficiency. When the outer conductor 4 is inserted through the connector 102, the sealing ring 6 can be interference-fitted with the inner wall of the connector 102, thereby preventing external dust and moisture from entering the connector.

[0032] like Figures 1 to 6 As shown, the inner diameter of the connector 102 is larger than the outer diameter of the outer conductor 4, so that a floating space is formed between the outer conductor 4 and the inner wall of the connector 102, allowing the outer conductor 4 to swing within a certain range. The floating snap ring 7 is set in the floating space between the outer conductor 4 and the inner wall of the connector 102, which can provide a certain elastic support for the inside of the connector, so that the relative position between the outer conductor 4 and the outer shell 1 can float within a certain range, or maintain a stable connection between the wire end connector and the board end connector 10 when subjected to external pressure and vibration.

[0033] Specifically, the floating snap ring 7 includes a cylindrical snap ring body 701 and a floating spring arm 702 formed by bending the side wall portion of the snap ring body 701 inward. Correspondingly, a limiting protrusion 103 is provided around the inner wall of the connector 102, and an outwardly protruding anti-retraction platform 404 is formed on the outer wall of the mating cylinder portion 402 to prevent the floating snap ring 7 from detaching from the outer conductor 4. One end of the snap ring body 701 abuts against the limiting protrusion 103, and the other end is riveted to the inner end face of the connector 102. There are multiple riveting points 703, which are evenly arranged circumferentially. The floating spring arm 702 elastically abuts against the outer conductor 4. By setting a floating snap ring between the outer conductor 4 and the outer housing 1, it can serve as a unit that provides the main force value for bearing the backward movement of the wire harness, while also allowing the wire harness to swing in a certain space to effectively compensate for the gap and deviation between the plug connector and the socket connector, reducing link loss and making the contact tighter and more reliable.

[0034] The rear cover 8 primarily serves to clamp the wire harness, preventing stress from being transmitted into the outer housing 1 during the swinging process of the coaxial cable 2. A through hole 801 is provided in the center of the rear cover 8 for the coaxial cable 2 to pass through. The rear cover 8 is coaxially sleeved on the outer end of the connector 102, clamping and fixing the coaxial cable 2. A locking hole 802 is provided on the side wall of the rear cover 8. Correspondingly, a barb 104 is formed on the outer wall of the connector 102 to cooperate with the locking hole 802. The rear cover 8 is locked and fixed to the connector 102. The rear cover 8 provides additional mechanical protection, preventing excessive swinging or twisting of the coaxial cable 2, preventing stress fatigue that could lead to loosening or disconnection of the coaxial cable 2. It also mitigates the risk of failure of the floating retaining spring 7, absorbing the force of secondary backward movement and improving the connection stability of the connector.

[0035] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
