[0029] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the utility model and implement it, but the embodiments are not intended to limit the utility model.

[0030] Reference Figure 1 to Figure 5 As shown, the utility model provides a split rear cover assembly structure for a split camera, comprising:

[0031] The rear cover 100 includes a body 110 and an insertion cavity 111 disposed in the body 110; a mounting groove 112 communicating with the insertion cavity 111 is disposed at the front end of the body 110, and the mounting groove 112 is used to assemble the floating board-end connector 03; a plurality of avoidance grooves 113 are disposed at intervals along the circumferential direction on the wall of the insertion cavity 111;

[0032] The metal buckle 200 includes a circular ring portion 210, a plurality of buckles 220, a plurality of connecting pieces 230 and a folded structure 240; the circular ring portion 210 is located in the insertion cavity 111, and a plurality of openings 211 are provided on the wall of the circular ring portion 210 along its circumferential direction, and the openings 211, the buckles 220 and the avoidance grooves 113 are provided one by one; the buckle 220 extends along the axial direction of the circular ring portion 210 and is located in the opening 211, and the buckle 220 includes a main body 221 and a bent portion 222; one end of the main body 221 is connected to the end of the opening 211, The other end is connected to the end of the bending portion 222, which is formed by bending inward from front to back relative to the annular portion 210; the connecting piece 230 is connected to the front end of the annular portion 210 and is formed by bending outward; the connecting piece 230 is arranged on the end face of the rear cover 100 and is fixedly connected to the rear cover 100; the folded structure 240 is connected to the front end of the annular portion 210, and the folded structure 240 is formed by bending outward from the front end of the annular portion 210; the folded structure 240 is arranged at the end face of the rear cover 100, and the folded structure 240 and the connecting piece 230 are arranged in a circumferentially staggered manner. When installing the split harness connector 02, the split harness connector 02 is inserted into the annular portion 210, so that the buckle 220 is pushed outward so that the buckle 220 is stuck in the avoidance groove 113; thereby realizing the rapid installation and disassembly of the split harness connector 02 and the split rear cover assembly 01, and realizing a stable and reliable connection.

[0033] Specifically, the metal clip 200 in this embodiment is fixedly connected to the rear cover 100 through the folded structure 240. Then the buckle 220 of the metal clip 200 facilitates the quick and detachable installation of the split wiring harness connector 02 in the plug-in cavity 111; and the folded structure 240 can withstand the pulling force of the wire harness of the split wiring harness connector 02 when it is used together with the buckle 220, so that the connection between the split wiring harness connector 02 and the split rear cover assembly 01 is more stable and reliable.

[0034] Furthermore, there are multiple inverted structures 240, and the multiple inverted structures 240 are arranged at intervals along the axial direction, so as to further improve the ability to withstand the pulling force when the wire harness is used.

[0035] Furthermore, the body 110 is provided with a first protrusion 114 at the front end where the insertion cavity 111 is provided, and the first protrusion 114 is provided with a first clamping groove 115 for installing the inverted structure 240. The first protrusion 114 is also provided with a second clamping groove 116 for installing the connecting piece 230. The first clamping groove 115 and the second clamping groove 116 are convenient for limiting the inverted structure 240 and the connecting piece 230 to prevent the metal clip 200 from rotating in the circumferential direction.

[0036] Furthermore, the inner wall of the first protrusion 114 is provided with a first chamfer 117. The first chamfer 117 is provided to avoid stress concentration after bending and easy fracture, thereby further improving the service life.

[0037] Furthermore, the annular portion 210 is provided with a gap 212. The gap 212 can finely adjust the diameter of the annular portion 210, so that the diameter of the annular portion 210 can be adjusted within a movable range so that it can be suitable for installation in the insertion cavity 111 of different diameters, further improving the application range.

[0038] Furthermore, the connecting piece 230 is fixed to the rear cover 100 by riveting. A riveting hole is provided on the connecting piece 230, and the connecting piece 230 is fixed to the rear cover 100 by riveting at the riveting hole. This can prevent the buckle 220 from falling off when the wiring harness connector is inserted. The riveting process is simple.

[0039] Furthermore, a second protrusion 118 is provided at the end of the body 110, the cross-sectional area of ​​the second protrusion 118 is smaller than the area of ​​the upper surface of the body 110, and the insertion cavity 111 passes through the second protrusion 118. In this embodiment, the second protrusion 118 is provided to ensure the axial length of the insertion cavity 111 while reducing the weight of the body 110.

[0040] Furthermore, second chamfers 119 are provided on both sides of the avoidance groove 113 .

[0041] Furthermore, the metal clip 200 is made of beryllium copper. In some embodiments, the metal clip 200 is bottom-plated with nickel and the surface is plated with tin, so as to further improve the service life of the metal clip 200.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the utility model creation.
