Technical Field

[0001] This utility model relates to the field of electrical auxiliary components technology, and in particular to a vehicle camera socket. Background Technology

[0002] There are numerous cameras installed inside high-speed trains, bullet trains, and subways to monitor the normal operation of various devices. These cameras are installed in suitable locations, and their connections are all via signal cable sockets.

[0003] Existing automotive camera sockets often experience connection difficulties when plugging in the coaxial connector of the camera due to insufficient concentricity. Furthermore, dust and rain entering the socket during vehicle operation can damage the internal circuitry and interfaces, leading to malfunctions. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems and provide a vehicle camera socket that achieves the coaxiality requirement between the connector and the back cover through a stepped hole.

[0005] The technical solution adopted by this utility model is:

[0006] A vehicle camera socket includes a front cover and a rear cover. A circuit board is disposed inside the front cover. The rear cover has an insertion hole and an extension hole section communicating with the insertion hole on its outer side. The insertion hole is a stepped hole. A connector is disposed inside the insertion hole. The connector includes a front interface, a rear interface, and a middle flange. The front interface extends into the extension hole section, and the middle flange is tightly fitted with the step of the insertion hole. The front interface is close to the end of the extension hole section, and the rear interface is electrically connected to the circuit board.

[0007] Furthermore, the middle flange of the connector is provided with knurling.

[0008] Furthermore, a sealing ring is provided between the step of the insertion hole and the middle flange of the connector, and the sealing ring is fitted onto the front interface.

[0009] Furthermore, multiple protrusions are provided on the circumference of the stepped hole, and the protrusions are tightly fitted with the central flange.

[0010] Furthermore, a snap-fit ​​structure is provided on the mounting surfaces of the front cover and the rear cover. The snap-fit ​​structure includes an annular protrusion on the mounting surface of the front cover and an upper annular groove on the mounting surface of the rear cover. When the front cover and the rear cover are installed together, the annular protrusion is snapped into the annular groove.

[0011] Furthermore, the front cover and the rear cover are fixed by fastening bolts, and the snap-fit ​​structure avoids the mounting holes of the fastening bolts.

[0012] The beneficial effects of this utility model are:

[0013] (1) The fit between the stepped hole and the middle flange of the connector ensures that the coaxiality between the connector and the back cover meets the insertion requirements;

[0014] (2) The snap-fit ​​structure between the front cover and the back cover keeps the circuit inside the camera socket sealed and unaffected by the external environment.

[0015] (3) Applicable to camera connection and use in various vehicles. Attached Figure Description

[0027] The following detailed description of a specific embodiment of the vehicle camera socket of this utility model is provided in conjunction with the accompanying drawings.

[0028] See appendix Figure 1 , 2 The vehicle camera socket of this application includes a front cover 1 and a rear cover 2. A circuit board 3 is provided inside the front cover 1, and a connector 4 is provided inside the rear cover 2. When the front cover 1 and the rear cover 2 are fastened together, a camera socket is formed.

[0029] See appendix Figure 3An insertion hole 5 is provided on the back cover 2. An extension hole section 6 communicating with the insertion hole 5 is provided on the outer side of the back cover 2. The insertion hole 5 is a stepped hole. A connector 4 is provided in the insertion hole 5. The connector 4 includes a front interface 7, a rear interface 8 and a middle flange 9. The front interface 7 extends into the extension hole section 6. The middle flange 9 is tightly fitted with the step of the insertion hole 5. The front interface 7 is close to the end of the extension hole section 6. The rear interface 8 is electrically connected to the circuit board 3.

[0030] Multiple protrusions 10 are provided on the circumference of the stepped hole. Three protrusions 10 are shown in the figure, evenly distributed on the circumference. Knurling is provided on the middle flange 9 of the connector 4. The middle flange 9 and the protrusions 10 form a tight fit, ensuring the coaxiality of the connector 4 and the insertion hole 5. In addition, a sealing ring is provided between the step of the insertion hole 5 and the middle flange 9 of the connector 4. The sealing ring is fitted onto the front interface 7. After the connector 4 and the insertion hole 5 are assembled, an adhesive application process is used to ensure that they will not loosen during use. The installed connector 4 maintains good coaxiality with the insertion hole 5 and the extension section 6 of the rear cover 2.

[0031] A snap-fit ​​structure is provided on the mounting surfaces of the front cover 1 and the rear cover 2. The snap-fit ​​structure includes an annular protrusion 11 on the mounting surface of the front cover 1 and an annular groove 12 on the mounting surface of the rear cover 2. When the front cover 1 and the rear cover 2 are installed together, the annular protrusion 11 is snapped into the annular groove 12. Alternatively, a sealing ring can be installed in the annular groove 12 before installing the annular protrusion 11 to ensure a good seal after the front cover 1 and the rear cover 2 are installed.

[0032] The front cover 1 and the rear cover 2 in the figure are fixed by fastening bolts 13. The fastening bolts 13 are located at the diagonal positions of the front cover 1 and the rear cover 2, and the annular protrusion 11 and annular groove 12 of the snap-fit ​​structure are arranged to avoid the installation position of the fastening bolts 13.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
