Description

Technical Field

[0001] The utility model relates to the technical field of automobile tail lamps, in particular to a lamp housing structure used for fixing a main connector of an automobile tail lamp and preventing wrong installation. Background Art

[0002] The taillights of a car remind the car behind you that there is a car in front of it when driving at night, and show the positional relationship between the two cars. Therefore, they are installed on both sides of the rear of the car. Currently, the taillights of trucks are installed on the rear end of the vehicle with bolts. The connection socket on the taillight is connected to the vehicle's line. Subsequently, the connection line is tied to the vehicle with cable ties.

[0003] The traditional method of using cable ties to bind and fix the connection lines and sockets to the vehicle may cause the risk of the main connector of the headlight falling off during the transportation and turnover of the entire lamp. On the automobile production line, the main connector of the taillight male end and the body female end are plugged together and fixed to the body sheet metal parts or the headlight plastic parts. The operator needs to use both hands at the same time during the plugging process, and there is still a risk of loosening or falling off after assembly. In view of this, we propose a lamp shell structure for fixing the main connector of automobile taillights and preventing misinstallation. Utility Model Content

[0029] In order to clamp the main connector 3 on the connecting bracket 2, the structure of the connecting bracket 2 is detailed as follows. Figure 3 The connecting bracket 2 includes an assembly frame 21, and a U-shaped clamp 22 is symmetrically fixedly connected to the upper surface of the assembly frame 21. A clamp block is symmetrically fixedly connected to the inner wall of the U-shaped clamp 22 near the upper end. After the main connector 3 is clamped in the U-shaped clamp 22 at a position below the clamp block, the two arms of the U-shaped clamp 22 clamp and fix the main connector 3 to limit the movement of the main connector 3 to the sides and downward, and the clamp block prevents the main connector 3 from moving upward from the inside of the U-shaped clamp 22.

[0030] In order to improve the stability of the main connector 3 and the connecting bracket 2 after being snap-fitted and assembled, the structure of the main connector 3 is detailed below. Figure 4 and Figure 5 The main connector 3 includes a body female end 31, and a card slot 32 is provided on the outer wall of the body female end 31. The upward side of the card block is an inclined surface with a lower inner side and a higher outer side. The two arms of the U-shaped clamp 22 are elastic. In the process of inserting the body female end 31 into the U-shaped clamp 22 from top to bottom, the moving card slot 32 contacts the inclined surfaces of the two card blocks, and pushes the two card blocks outward, and the two arms of the U-shaped clamp 22 are elastically deformed. When the card slot 32 moves between the two card blocks to a position in contact with the bottom surface of the U-shaped clamp 22, the movement of the body female end 31 is stopped, and the card block is disengaged from the card slot 32, and the two arms of the U-shaped clamp 22 are used. The main connector 3 is firmly fixed to the inner surface of the card slot 32, and the main connector 3 is firmly fixed to the inner surface of the card slot 32, so that the ...

[0031] In order to firmly install the assembly consisting of the main connector 3 and the connecting bracket 2 on one side of the lamp housing body 1, refer to Figure 6 , Figure 7 and Figure 8 A positioning rod 23 and a reverse lever 24 are fixedly connected to the lower surface of the assembly frame 21, and two positioning grooves are opened on one side of the lamp housing body 1, one of the positioning grooves is slidably sleeved on the outside of the positioning rod 23, and a buckle is fixedly connected to the inner wall of the other positioning groove, and the buckle is buckled with the reverse lever 24. The positioning rod 23 and the reverse lever 24 cooperate with the two positioning grooves respectively to limit the horizontal and downward movement of the assembly frame 21 on the lamp housing body 1, and the buckle cooperates with the reverse lever 24 to limit the reverse lever 24 from being pulled out from the inside of the positioning groove, limiting the upward movement of the assembly frame 21 on the lamp housing body 1, and then the assembly frame 21 is clamped and fixed to one side of the lamp housing body 1, completing the stable installation of the assembly parts composed of the main connector 3 and the connecting bracket 2.
