The connecting handle has an L-shaped structure, and its connecting end connects to the positioning end of the base. A wire-passing hole is provided on the side wall of the connecting end of the connecting handle. Thus, when the installation space for the automotive bulb is limited, the L-shaped connecting handle of this invention can be used to change the installation and fixing position of the bulb holder, thereby solving the installation difficulties caused by limited installation space in existing automotive bulb holders. Furthermore, the wire-passing hole on the side wall of the connecting end of the connecting handle facilitates the connection of this invention's automotive bulb holder to the power supply wires on the vehicle body.

[0004] Preferably, a connecting buckle is provided on the outer wall of the positioning end of the base, and a connecting groove is provided on the side wall of the connecting end of the connecting handle. When the positioning end of the base is connected to the connecting end of the connecting handle, the connecting buckle is engaged with the connecting groove. Thus, the connecting end of the connecting handle and the positioning end of the base in this automotive bulb holder are connected by a buckle, making the connection simple and convenient. Furthermore, a guide surface, which is arc-shaped, is provided on the side of the connecting buckle facing the connected handle. When assembling this automotive bulb holder, when the connecting end of the connecting handle is engaged with the positioning end of the base, the arc-shaped guide surface on the connecting buckle guides and supports the outward expansion of the side wall of the connecting end of the connecting handle, allowing the connecting buckle to engage with the connecting groove on the connecting handle. This facilitates the engagement of the connecting buckle and the connecting groove, improves the assembly efficiency of this automotive bulb holder, and prevents damage to the connecting handle during the connection process.

[0005] Preferably, a positioning plate is provided on the outer side of the positioning end of the base, and a positioning slot is provided on the side wall of the connecting end of the connecting handle. When the base is connected to the connecting handle, the positioning plate is inserted into the positioning slot. Thus, when assembling the automotive bulb holder of this invention, the positioning plate on the base and the positioning slot on the connecting handle can be used for positioning, improving assembly efficiency. Further, the mounting end of the base is provided with an insertion slot for mounting a metal terminal, and the inner wall of the insertion slot is provided with a limiting slot for locking the limiting barbs on the metal terminal; a positioning protrusion is provided on the edge of the insertion slot, and the positioning protrusion corresponds to the position of the limiting slot. Thus, when assembling the automotive bulb holder of this invention, the limiting slot can be used to lock the limiting barbs on the metal terminal to limit the metal terminal, preventing the metal terminal from falling out of the insertion slot on the base and affecting the operation of the automotive bulb. More preferably, the inner wall of the insertion slot is provided with a foolproof structure, and the foolproof structure is close to the limiting slot. In this way, when installing automotive bulbs, the foolproof structure can be used to guide the insertion end of the automotive bulb into the insertion slot, avoiding incorrect insertion of the automotive bulb and affecting the installation efficiency of the automotive bulb.

[0006] Preferably, the mounting end of the base is provided with a through-glue groove, and the through-glue groove is located on both sides of the insertion groove. In this way, when the base of the automotive bulb holder of this utility model is injection molded, it can avoid the problem of through-glue in the injection-molded base, and also prevent uneven wall thickness at the mounting end of the injection-molded base, or even shrinkage problems, which would affect the yield of the injection-molded base and thus improve the yield of the automotive bulb holder of this utility model.

[0007] Preferably, the outer wall of the mounting end of the base is provided with multiple mounting buckles, and at least two of the mounting buckles have limiting grooves on their buckle surfaces facing the positioning end. Thus, when the mounting end of the automotive bulb holder of this invention is connected to the matching accessory, the mounting buckles on the mounting end of the base can be connected to the matching accessory buckles by rotating the base, making the connection simple and convenient. The limiting grooves on the buckle surfaces of the mounting buckles can be used to hold the protrusions on the matching accessory, preventing excessive rotation of the base and affecting installation efficiency. Further, the base is provided with a positioning ring plate, which is located around the connection between the mounting end and the positioning end; a sealing ring is fitted on the mounting end, and the sealing ring is located between the positioning ring plate and the mounting buckles. Thus, fitting a sealing ring on the mounting end of the base can effectively improve the sealing performance between the mounting end of the automotive bulb holder of this invention and the matching accessory. More preferably, the sealing surface of the sealing ring has a wavy structure. In this way, the sealing surface of the sealing ring is designed with a wavy structure, which can effectively increase the contact area of ​​the sealing surface, thereby effectively improving the sealing performance of the sealing ring. In addition, the increased contact area of ​​the sealing surface can increase the friction of the sealing surface, preventing the automotive bulb holder from sliding due to reduced friction between the mounting end and the matching part, or even causing the automotive bulb holder to separate from the matching part, thus affecting the installation stability of the automotive bulb.

[0013] Below, in conjunction with Figures 1 to 5 This invention provides a detailed description of the automotive bulb holder.

[0014] like Figures 1 to 5As shown, this utility model of an automotive bulb holder includes a base 1 and a connecting handle 2. The connecting handle 2 has an L-shaped structure, and its connecting end 21 is connected to the positioning end 11 of the base 1. A wire hole 211 is provided on the side wall of the connecting end 21 of the connecting handle 2. Thus, when the installation space for the automotive bulb is limited, the L-shaped connecting handle 2 of this utility model can be used to change the installation and fixing position of the bulb holder, thereby solving the installation difficulty problem caused by limited installation space in existing automotive bulb holders. In addition, the wire hole 211 on the side wall of the connecting end 21 of the connecting handle 2 facilitates the connection of this utility model's automotive bulb holder to the power supply wires on the vehicle body. In the specific implementation of this utility model's automotive bulb holder, the shape and structure of the positioning end 22 of the connecting handle 2 can be adjusted according to the shape of the installation space for the automotive bulb. Preferably, a connecting buckle 111 is provided on the outer wall of the positioning end 11 of the base 1, and a connecting groove 212 is provided on the side wall of the connecting end 21 of the connecting handle 2. When the positioning end 11 of the base 1 is connected to the connecting end 21 of the connecting handle 2, the connecting buckle 111 is snapped into the connecting groove 212. Thus, the connecting end 21 of the connecting handle 2 and the positioning end 11 of the base 1 in this invention are connected by a buckle, making the connection simple and convenient. When assembling this invention's automotive bulb holder, the port of the connecting end 21 of the connecting handle 2 is fitted around the positioning end 11 of the base 1, and the connecting buckle 111 is inserted into the connecting groove 212 on the side wall of the connecting end 21 of the connecting handle 2 to achieve a snap-fit ​​connection with the connecting groove 212. Preferably, the connecting buckle 111 has a guide surface 1111 on the side facing the connected handle 2, and this guide surface 1111 is an arc-shaped surface. Thus, when assembling the automotive bulb holder of this utility model, when the connecting end 21 of the connecting handle 2 is snapped into the positioning end 11 of the base 1, the arc-shaped guide surface 1111 on the connecting buckle 111 guides and supports the outward expansion of the side wall of the connecting end 21 of the connecting handle 2, so that the connecting buckle 111 is snapped into the connecting slot 212 on the connecting handle 2. This facilitates the snapping of the connecting buckle 111 into the connecting slot 212, improves the assembly efficiency of the automotive bulb holder of this utility model, and avoids damage to the connecting handle 2 by the connecting buckle 111 during the connection process. Preferably, a positioning plate 112 is provided on the outer side of the positioning end 11 of the base 1, and a positioning slot 213 is provided on the side wall of the connecting end 21 of the connecting handle 2. When the base 1 is connected to the connecting handle 2, the positioning plate 112 is inserted into the positioning slot 213. In this way, when assembling the automotive bulb holder of this utility model, the positioning plate 112 on the base 1 and the positioning slot 213 on the connecting handle 2 can be used for positioning, thereby improving assembly efficiency.Preferably, two opposing positioning plates 112 are provided on the outer side of the positioning end 11 of the base 1, and at least two pairs of connecting buckles 111 are provided on the outer wall of the positioning end 11 of the base 1, with the pairs of connecting buckles 111 being oppositely arranged on both sides of the plane where the two positioning plates 112 are located. In this way, the positioning end 11 of the base 1 is connected to the connecting end 21 of the connecting handle 2 by at least two pairs of connecting buckles 111, which can effectively improve the connection stability between the positioning end 11 of the base 1 and the connecting end 21 of the connecting handle 2.

[0015] like Figures 2 to 5As shown, the mounting end 12 of the base 1 is provided with an insertion groove 121 for mounting a metal terminal 3, and the inner wall of the insertion groove 121 is provided with a limiting groove 1211 for locking the limiting barb 31 on the metal terminal 3; a positioning protrusion 1212 is provided on the edge of the insertion groove 121, and the positioning protrusion 1212 corresponds to the position of the limiting groove 1211. In this way, when assembling the automotive bulb holder of this utility model, the limiting groove 1211 can be used to lock the limiting barb 31 on the metal terminal 3 to limit the metal terminal 3, preventing the metal terminal 3 from falling out of the insertion groove 121 on the base 1 and affecting the operation of the automotive bulb. Preferably, the inner wall of the insertion groove 121 is provided with a foolproof structure 1213, and the foolproof structure 1213 is close to the limiting groove 1211. Thus, when installing automotive bulbs, the foolproof structure 1213 can guide the insertion end (not shown in the figure) of the automotive bulb 4 into the insertion slot 121, avoiding incorrect insertion of the automotive bulb 4 and affecting the installation efficiency of the automotive bulb 4. Preferably, the mounting end 12 of the base 1 is provided with a through-glue groove 122, and the through-glue groove 122 is located on both sides of the insertion slot 121. In this way, when the base 1 in the automotive bulb holder of this utility model is injection molded, it can avoid the problem of through-glue in the injection molded base 1, and can also prevent uneven wall thickness of the mounting end 12 of the injection molded base 1, or even shrinkage problems, which would affect the yield of the injection molded base 1, thereby improving the yield of the automotive bulb holder of this utility model. Preferably, the outer wall of the mounting end 12 of the base 1 is provided with a plurality of mounting buckles 123, and at least two mounting buckles 123 are provided with limit grooves 1231 on the buckling surface (not shown in the figure) facing the positioning end 11. Thus, when the mounting end 12 of the automotive bulb holder of this utility model is connected to the matching part, the mounting clip 123 on the mounting end 12 of the base 1 can be connected to the matching part clip by rotating the base 1, making the connection simple and convenient. The limiting groove 1231 on the clip surface of the mounting clip 123 can be used to lock the protrusion on the matching part, preventing the base 1 from rotating too much and affecting the installation efficiency. Preferably, the limiting end of the mounting clip 123 with the limiting groove 1231 is provided with a limiting block 124. Thus, when the mounting end 12 of the automotive bulb holder of this utility model is screwed to the matching part, the limiting block 124 can be used to limit the amount of screwing of the matching part, preventing the mounting end 12 of the automotive bulb holder of this utility model from separating from the matching part due to excessive screwing, which would affect the connection effect and connection efficiency between the automotive bulb holder of this utility model and the matching part of the mounting end 12. Preferably, the insertion end of the mounting clip 123 is provided with a screw guide surface 1232, and the screw guide surface 1232 is inclined relative to the snap-fit ​​surface of the mounting clip 123 and connected to the snap-fit ​​surface. In this way, when the mounting end 12 of the automotive bulb holder of this utility model is connected to the matching accessory, the screw guide surface 1232 can be used to guide the clip on the matching accessory, which facilitates the connection between the mounting end 12 of the automotive bulb holder of this utility model and the snap-fit ​​of the matching accessory.Preferably, a positioning ring plate 13 is provided on the base 1, which is located on the periphery of the connection between the mounting end 12 and the positioning end 11; a sealing ring 5 is fitted on the mounting end 12, and the sealing ring 5 is located between the positioning ring plate 13 and the mounting buckle 123. Thus, fitting the sealing ring 5 on the mounting end 12 of the base 1 effectively improves the sealing performance between the mounting end 12 of the automotive bulb holder and the matching parts. Preferably, the sealing surface 51 of the sealing ring 5 has a wavy structure. This wavy structure effectively increases the contact area of ​​the sealing surface 51 of the sealing ring 5, thereby effectively improving the sealing performance of the sealing ring 5. Furthermore, the increased contact area of ​​the sealing surface 51 of the sealing ring 5 increases the friction of the sealing surface 51, preventing the automotive bulb holder from sliding due to reduced friction between the mounting end 12 and the matching parts, or even causing the automotive bulb holder to separate from the matching parts, thus affecting the installation stability of the automotive bulb.
