[0064] For the automobile combination headlamp wire harness connection structure, with the functional diversification of the automobile lamp 1000, the vehicle space arrangement is increasingly compact, and the wire harness connection structure is increasingly integrated. In the related art, a sliding tunnel (i.e., the inside of the pipe body) is designed on the lamp shell 300, the pin 30 and the base 20 are integrally injection molded to form the lamp plug 100, and then are integrated on the PCBA (i.e., the circuit board 10), and then are installed through the sliding tunnel of the lamp shell 300 and the vehicle body main wire harness socket (i.e., the wire harness connector 200). Since the plug is integrally injection molded by the pin 30 and the base 20, the relative positions of the pins 30 will change, the lamp shell 300 will be deformed during injection molding, and the pin 30 is slender in shape, which will cause the plug and the socket to be installed through the sliding tunnel of the lamp shell 300, the pin 30 to be withdrawn from the base 20, the pin 30 to be bent and unable to be normally assembled, the whole lamp to be unable to normally light, and the like. As known from the foregoing, the deformed size of the lamp shell 300 is difficult to control, the pin 30 and the base 20 are integrally injection molded, and the relative positions of the pins 30 are difficult to guarantee. During the assembly process of the connector, the pin 30 is bent, withdrawn, and the like.

[0065] Therefore, the embodiments of the utility model propose a lamp plug 100, which comprises a pin 30 (which can be made of brass, phosphor copper or the like), a base 20 (which can be made of PC, PA66 or the like), and an elastic cover plate 50 (which can be made of PC, PA66 or the like). By changing the surface state of the pin 30, the pin 30 is prevented from being displaced from the base 20, and the wire harness plugging process is completed through the sliding clamping mode with the elastic cover plate 50, the vehicle body wire harness socket and the sliding tunnel of the lamp shell 300, so as to avoid the problems of pin withdrawal and bending of the pin 30 during the assembly process.

[0066] Specifically, bidirectional barbs are added in the movement direction (i.e., the length direction of the pin 30) of the pin 30, and through holes (i.e., anti-dropping holes 41) are added on the side surface, so that the pin 30 does not displace after being integrally injection molded with the base 20. The base 20 is provided with buckles 21 and a sliding cooperation structure (i.e., a guide groove 22), the elastic cover plate 50 is slidingly clamped with the base 20, the sliding tunnel of the lamp shell 300 can be provided with four guide rails to guide the precise connection of the wire harness connection seat and the lamp plug 1000. The lamp 1000 comprises a vehicle body wire harness socket, a sealing ring, a lamp shell 300, an elastic cover plate 50, a base 20, a pin 30 and a PCBA.
