Problems solved by technology
[0007] However, in the above-mentioned known technology, the isolation effect that the first shutter 121 and the second shutter 131 can produce cannot completely isolate the above-mentioned wire connection cavity from the bulb connection cavity, so there will still be Part of the sealing material seeps into the bulb connection cavity
Once the sealing material penetrates, it will adhere to the first bulb connection end 123 in the first bulb connection cavity, and / or the second bulb connection end 133 in the second bulb connection cavity 152, causing a gap between the bulb 17 and the metal terminal. Poor electrical contact
In this way, the car light source flickers and goes on and off, which endangers driving safety.

The lamp holder structure of the car lamp can be filled with a sealing material to protect various internal parts from being damaged by external factors. The lamp holder structure of the car lamp of the invention comprises a lead installation part, a bulb installation part and a terminal inserting hole; wherein, the lead installation part has a groove used for being filled with the sealing material.
Description
technical field [0001] The invention relates to a lamp holder structure for a car lamp, in particular to a sealed lamp holder structure for a car lamp capable of sealing wires, a wire harness assembly for the lamp holder and a manufacturing method for the wire harness assembly for the lamp holder. Background technique [0002] In the known structure of the lamp holder of the automobile lamp, how to securely bond the wires in the lamp holder is an important issue. In particular, the car often encounters bumpy roads and high driving speeds when driving. If the wires cannot be tightly fixed in the lamp socket, it may cause poor electrical contact and make the light source of the car flicker. In severe cases, it will endanger driving. human life safety. [0003] Please also refer to Figure 1 to Figure 3 , A known car lamp holder structure includes a first metal terminal 12, a second metal terminal 13, a wire mounting portion 14, a bulb mounting portion 15, a first terminal ins...
