Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and in particular relates to a split-type camera elbow rear cover connector. Background Technology

[0002] Currently, most cars are equipped with in-vehicle cameras, which are image acquisition devices installed in vehicles to monitor the surrounding environment. They offer advantages such as convenient reversing, driving recording, and real-time observation of the vehicle's interior and exterior environment. With the accelerating pace of automotive intelligence, in-vehicle cameras, as core sensing units in autonomous driving systems, place higher demands on the signal transmission stability, mechanical reliability, and environmental adaptability of their connectors.

[0003] Traditional one-piece plastic elbow rear cover connectors have significant drawbacks: First, the complex internal structure requires multiple sets of clips and manual adjustment for assembly, resulting in cumbersome procedures, poor assembly consistency, and connection failure due to clip aging over long-term use. Second, the plastic material has insufficient bending strength, making it prone to root breakage under vehicle vibration or wiring harness tension, thus damaging the waterproof seal. Third, the plastic rear cover connector has poor electromagnetic shielding performance, making it susceptible to interference during high-frequency signal transmission. Although a one-piece metal molding solution can improve shielding and strength, high-precision automated production of one-piece metal camera elbow rear cover connectors is difficult due to limitations in processing technology and assembly difficulty.

[0004] Therefore, there is an urgent need for a new type of camera elbow rear cover connector architecture that takes into account high mechanical strength, high reliability, full shielding effectiveness, and industrial production adaptability. Utility Model Content

[0005] The purpose of this invention is to design a split-type camera bend rear cover connector to solve the problems of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A split-type camera elbow rear cover connector includes a rear cover, a plug-in body, and a center terminal assembly. The connector includes a cavity structure with a panel and a through hole formed on the panel and communicating with the cavity structure. The plug-in body is L-shaped and includes a plug for mating with a female connector of a vehicle wiring harness and a connector fixed in the through hole for connecting with a board-end connector on a camera circuit board. The plug has a first mounting cavity extending through the front and rear, and the connector has a second mounting cavity communicating with and perpendicular to the first mounting cavity. The center terminal assembly includes a first terminal assembly coaxially fixed in the first mounting cavity and a second terminal assembly coaxially fixed in the second mounting cavity, with the first terminal assembly and the second terminal assembly in electrical contact.

[0008] Furthermore, both the back cover and the plug-in body are made of metal, and the connection between the plug-in body and the back cover is formed by a riveting and extrusion process to create a mechanical interlocking structure.

[0009] Furthermore, the panel of the rear cover is provided with a positioning groove of a certain depth, and a fixing groove is also provided in the middle of the positioning groove, and the through hole is provided in the middle of the fixing groove; correspondingly, the connector includes a positioning part and a fixing part respectively embedded in the positioning groove and the fixing groove, and a sleeve part inserted into the through hole.

[0010] Furthermore, the first terminal assembly includes a first center pin and a first insulator, the first insulator coaxially fixing the first center pin within the first mounting cavity; the second terminal assembly includes a second center pin and a second insulator, the second insulator coaxially fixing the second center pin within the second mounting cavity, and the second center pin being in electrical contact with the first center pin.

[0011] Furthermore, the non-intercepting end of the first center pin is cut and formed with grooves.

[0012] Furthermore, the first insulator is also provided with a groove structure for introducing air dielectric to optimize impedance matching.

[0013] Furthermore, the rear end of the first mounting cavity is provided with a shielding cover for improving the electromagnetic shielding of the connector.

[0014] Furthermore, the connector is a FAKRA head, including a snap-fit ​​integrally formed on the outer wall of the connector and a guide rib parallel to the insertion direction.

[0015] Furthermore, an adhesive groove is provided at the joint between the inner wall of the rear cover and the plug-in body. Adhesive is filled into the adhesive groove and forms a waterproof sealing layer after curing.

[0016] Furthermore, the joint between the front and rear ends of the first mounting cavity is also filled with adhesive to form a double waterproof sealing structure.

[0017] Compared with the prior art, the beneficial technical effects of this split-type camera elbow rear cover connector provided by this utility model are as follows:

[0018] 1. This utility model adopts a split design of the plug-in main body and the back cover.

[0019] 2. This utility model forms a continuous conductive circuit by setting a shielding cover at the end of the plug-in body, achieving 360° full-wrap electromagnetic shielding, effectively suppressing interference noise in high-frequency signal transmission, and ensuring the integrity of high-definition video signals.

[0020] 3. This utility model can introduce air medium to optimize impedance matching and reduce signal attenuation by cutting and forming a groove of a certain depth at the non-intercepting end of the first center pin and forming a groove structure on the insulator.

Detailed Implementation

[0030] 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.

[0031] This utility model embodiment provides a split-type camera bend rear cover connector, including a rear cover 1, a plug-in body, and a center terminal assembly. Specifically:

[0032] like Figures 1 to 4 As shown, in this embodiment, the rear cover 1 is integrally die-cast or milled from metal material, including a rectangular panel 101 and a matching cavity structure, which can effectively eliminate electromagnetic interference, play a shielding role, and improve the quality of signal transmission. Furthermore, the panel 101 of the rear cover 1 has a positioning groove 102 of a certain depth. The positioning groove 102 is a rounded rectangle, and a rectangular fixing groove 103 is also formed in the middle of the positioning groove 102. A circular through hole 104 communicating with the cavity structure is formed in the middle of the fixing groove 103 for subsequent installation of the main body.

[0033] The connector body is L-shaped and integrally formed from metal material, including a connector 2 and a connecting head 3 perpendicular to the connector 2. The connector 2 is a Fakra connector, which directly mates with the Fakra female end of the vehicle body wiring harness. It includes a first mounting cavity, a guide rib 201, and a snap fastener 202. The first mounting cavity extends through the connector 2 along the insertion direction for subsequent installation of the first terminal assembly. The snap fastener 202 and the guide rib 201 are integrally formed on the outer wall of the connector 2, and the guide rib 201 is parallel to the insertion direction of the connector 2. The insertion end of the connector 2, i.e., the end away from the rear cover 1, also has an inner chamfer. The guide rib 201 and the inner chamfer provide positioning and guidance during connector mating, thereby ensuring the insertion accuracy of the connector. The snap fastener 202 allows the Fakra head to engage with the Fakra female end of the vehicle body wiring harness, ensuring a reliable connection of the camera bend rear cover connector.

[0034] like Figure 3 and 4As shown, the connector 3 consists of a positioning part 301, a fixing part 302, and a sleeve part 303 from top to bottom. The positioning part 301 and the fixing part 302 are respectively embedded in the positioning groove 102 and the fixing groove 103 to improve the resistance to lateral loads and vibration tolerance. The sleeve part 303 is inserted into the through hole 104 and is riveted to the rear cover 1 at the connection point by a riveting and extrusion process, thereby forming a mechanical interlocking structure in the axial and radial directions to ensure a rigid connection between the connector body and the rear cover 1. The connector 3 has a second mounting cavity that communicates with and is perpendicular to the first mounting cavity. The axis of the second mounting cavity is coaxial with the axis of the board-end connector on the camera circuit board. The opening end of the second mounting cavity has an inner chamfer. When the second terminal assembly is installed in the second mounting cavity, a blind-fit alignment interface is formed, which is connected to the board-end connector on the camera circuit board.

[0035] like Figures 3 to 5 As shown, in this embodiment, the center terminal assembly includes a first terminal assembly coaxially fixed in a first mounting cavity and a second terminal assembly coaxially fixed in a second mounting cavity, with the first terminal assembly and the second terminal assembly in electrical contact. Specifically, the first terminal assembly includes a first center pin 4 and a first insulator 5, with the first insulator 5 coaxially fixing the first center pin 4 in the first mounting cavity. Furthermore, in a preferred embodiment, the non-interlocking end of the first center pin 4 is also cut with a groove 401 of a certain depth to reduce the effective cross-sectional area of ​​the end of the first center pin 4, increase the equivalent inductance, and address the low impedance caused by subsequent adhesive application. The first insulator 5 also has a groove structure 501, which can introduce air to optimize impedance matching and reduce signal attenuation. The second terminal assembly includes a second center pin 6 and a second insulator 7, with the second insulator 7 coaxially fixing the second center pin 6 in the second mounting cavity. The second center pin 6 and the first center pin 4 are fixed by solder to form an electrical conduction path.

[0036] like Figure 3 As shown, to improve the waterproof and dustproof rating of the connector, an adhesive groove is provided at the joint between the inner wall of the back cover 1 and the connector head 3. Adhesive 8 is filled in the adhesive groove, and after curing, it forms a waterproof sealing layer to prevent external dust and moisture from entering the connector through the gap between the back cover 1 and the connector head 3. In addition, the joints at the front and rear ends of the first mounting cavity are also filled with adhesive 8 to further fill the gaps between the insertion body and the insulator, as well as between the insulator and the center pin, forming a double waterproof sealing structure.

[0037] In a preferred embodiment, a shielding cover 9 is provided at the rear end of the first mounting cavity. The shielding cover 9 is fixed to the plug-in body by riveting on a machine, so that the edge of the shielding cover 9 undergoes plastic deformation and covers the mating surface of the plug-in body, forming a fully enclosed electromagnetic shielding cavity with 360° continuous conductivity, so that the product has better shielding performance.

[0038] 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.
