[0002] In existing automotive bulb sockets, glue is used to ensure the sealing requirements between the wire and the bulb socket. However, the glue material cures slowly, pollutes the environment, and has low manufacturing efficiency. Summary of the Invention

[0003] To address the problems of slow curing of potting materials, environmental pollution, and low manufacturing efficiency in existing automotive bulb holders, this invention proposes an automotive bulb holder comprising a base and metal terminals. The mounting end of the base has a bulb insertion slot, and the positioning end has a wiring slot. A metal terminal slot connects the bulb insertion slot and the wiring slot. The metal terminal is inserted into the metal terminal slot, and its terminal connects to a power cord inserted through the wiring slot. A wire sealing sleeve is provided in the wiring slot, fitting over the power cord and providing an interference fit. Thus, the wire sealing sleeve in the wiring slot of this invention fills the gap between the inner wall of the wiring slot and the power cord connected to the metal terminal. Therefore, this automotive bulb holder, by using a wire sealing sleeve to replace the potting process in existing technologies, effectively solves the problems of slow curing of potting materials, environmental pollution, and low manufacturing efficiency.

[0004] Preferably, a snap-fit ​​groove is provided on the outer wall of the snap-fit ​​end of the wire sealing sleeve near the metal terminal slot, and a retaining plate provided on the wiring end of the metal terminal is engaged in the snap-fit ​​groove. This snap-fit ​​groove on the outer wall of the snap-fit ​​end of the wire sealing sleeve allows the retaining plate on the wiring end of the metal terminal to be engaged in the snap-fit ​​groove when the wire sealing sleeve is installed in the wiring slot, thereby improving the installation stability of the wire sealing sleeve in the wiring slot and preventing the wire sealing sleeve from falling out of the wiring slot during vehicle operation, which would affect the use of the vehicle lights. Furthermore, both the inner wall of the wire sealing sleeve and the outer wall of the wire sealing sleeve away from the sealing end of the metal terminal slot are provided with a corrugated structure. This corrugated structure on both the inner and outer walls of the wire sealing sleeve improves the sealing performance between the wire sealing sleeve and the power cord and the inner wall of the wiring slot.

[0005] Preferably, a snap-fit ​​platform is provided on the side wall of the metal terminal slot on the base, and the snap-fit ​​platform faces the bulb insertion slot and is close to the outer edge of the mounting end; when the metal terminal is installed in the metal terminal slot, the barb on the metal terminal is engaged with the snap-fit ​​platform. Thus, the snap-fit ​​platform on the side wall of the metal terminal slot secures the barb on the metal terminal when it is installed, preventing the metal terminal from falling out of the slot. Furthermore, two handles are provided on the periphery of the positioning end of the base, and these two handles are symmetrically arranged on both sides of the positioning end. Thus, when the mounting end of the automotive bulb holder of this invention is connected to the matching parts, the assembler only needs to rotate the automotive bulb holder by operating the two handles, making operation simple and convenient.

[0006] Preferably, a pair of terminal positioning slots are provided on the side wall of the metal terminal slot, and the pair of terminal positioning slots are arranged opposite to each other on both sides of the inverted locking platform; when the metal terminal is inserted into the metal terminal slot, the connecting end of the metal terminal facing the bulb insertion slot is locked in the terminal positioning slot. Thus, by providing a pair of terminal positioning slots on the side wall of the metal terminal slot, the connecting ends of the metal terminal are locked in place when the metal terminal is installed in the metal terminal slot, preventing the metal terminal from shifting or misaligning within the metal terminal slot, and further improving the installation stability of the metal terminal in the metal terminal slot. Further, a pair of insertion guide slopes are provided on the inner wall of the connection portion between the wiring slot hole and the metal terminal slot, and the pair of insertion guide slopes are arranged opposite to each other on both sides of the inverted locking platform, and the positions of the insertion guide slopes correspond to the corresponding terminal positioning slots. In this way, when assembling the automotive bulb holder of this utility model, the insertion guide bevel can be used to guide the metal terminal inserted into the metal terminal slot, which facilitates the insertion of the metal terminal and improves the assembly efficiency of the automotive bulb holder of this utility model.

[0007] Preferably, a connecting buckle is provided on the outer wall of the mounting end on the base. The connecting buckle has a positioning groove on its engagement surface facing the positioning end, and a limiting block protruding towards the positioning end is provided on the limiting end of the connecting buckle. Thus, when the mounting end of the automotive bulb holder of this invention is connected to a matching accessory, the connecting buckle can be used for connection, making the connection simple and convenient. The positioning groove on the engagement surface of the connecting buckle secures the positioning protrusion on the matching accessory, facilitating the assembly personnel's judgment of whether the automotive bulb holder of this invention is properly assembled during assembly. The limiting block on the limiting end of the connecting buckle limits the matching accessory during assembly, preventing excessive rotation of the automotive bulb holder of this invention and affecting its assembly efficiency.

[0008] Preferably, the mounting end of the base is provided with a through-glue groove, and the through-glue groove is distributed around the bulb insertion slot. In this way, providing a through-glue groove on the mounting end of the base can not only avoid glue leakage problems during injection molding of the base, but also prevent uneven wall thickness of the mounting end of the injection molded base, or even shrinkage problems, which would affect the yield of the injection molded base.

[0009] Preferably, the metal terminal includes two clamping springs, which are arranged opposite to each other on both sides of the barbed buckle, and the two clamping springs are provided with opposing clamping protrusions. Thus, when the automotive bulb is assembled onto the automotive bulb holder of this invention, the two clamping springs of the metal terminal can clamp the connecting end of the automotive bulb, and the clamping protrusions on the clamping springs are engaged in the grooves on the connecting end of the automotive bulb. This improves the installation stability of the automotive bulb on the automotive bulb holder of this invention, preventing the automotive bulb from falling off the holder during vehicle operation, and also ensures sufficient contact between the metal terminal and the filament of the automotive bulb, preventing malfunctions due to poor contact.
