[0001] The invention relates to the technical field of vehicle lamp manufacturing, and in particular to a small-space self-sealing structure power supply and signal transmission lamp. Background Art
[0002] With the evolution of the current car taillight shape, the function and shape of the lamps are becoming more and more complex, and more requirements are placed on the space of the lamps. However, the signal transmission and power supply solutions of the lamps still rely on traditional wiring harness sheaths or connector structures. Such structures cannot achieve the sealing effect of the lamp body, and there is a risk of failure in waterproofing, insect-proofing and dust-proofing. At the same time, during the installation of the lamp, the wiring harnesses on the lamp end and the body end need to be plugged in, and some redundant wiring harnesses need to be reserved, resulting in waste. More importantly, the wiring harness sheath or connector structure for plugging in the body and the lamp has certain requirements for sheet metal and lamp space. The lamp housing needs to be made larger and the sheet metal needs to be stamped deeper, which is not conducive to the cost compression of the entire vehicle. Summary of the invention
