[0002] An automotive lamp holder is an important part of an automotive headlamp. Its main function is to fix the bulb and connect to the power supply. In the prior art, in the utility model patent with the publication number CN108800043B, a new energy automotive lamp holder that is easy to install is disclosed. It includes a bulb mounting base, and an installation ring is fixedly connected to the outer surface of the rear end of the bulb mounting base. A wire is provided inside the installation ring. In this structure, the wire is installed inside the installation ring, and during the assembly process, the wire is easily pulled by gravity, resulting in the separation of the wire from the plug-in connector and causing the lamp holder to be unable to be powered on. Summary of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that during the assembly process, the wire is easily pulled by gravity, resulting in the de-welding of the conductive wire from the power-on contact and causing the lamp holder to be unable to be powered on, so as to provide a lamp holder housing that can effectively protect the connection between the wire and the power-on contact.

[0004] To this end, the utility model provides a lamp holder housing, which includes a base and a wire installation groove opened on the side of the base. One end of the wire passes through the base and is connected to an external plug-in connector, the middle end is fixed in the wire installation groove, and the other end extends outside the base and is connected to an external part.

[0005] Further: The base is arranged in a ring structure, and a plurality of extension blocks are arranged in the wire installation groove. There is a gap between adjacent extension blocks, and a positioning groove for positioning the wire is formed at the gap.

[0006] Further: The opposite side surfaces of the positioning groove are arranged in a wavy structure and form an arc surface that can fit the outer end surface of the wire.

[0007] Further: A guiding inclined surface for guiding the wire to be inserted is arranged at the opening of adjacent extension blocks.

[0008] Further: An extension ring is arranged on the base, and the extension ring is coaxially arranged with the base. The extension blocks are arranged on the side surface of the extension ring.

[0009] Further: A plurality of reinforcing ribs are also arranged between the base and the extension ring, and the reinforcing ribs are arranged in a circumferential array with the center of the extension ring as the axis.

[0010] The technical solution of the utility model has the following advantages:

[0011] 1. A lamp socket housing provided by the utility model has the initial end of a wire passing through the interior and connecting to an external connector, the middle end being fixed in a wire installation groove, and the end extending outside the base and connecting to an external component. After the wire is installed, epoxy resin is poured into the interior of the base to fix the position of the middle end of the wire. When installing the base, it will not cause the separation of the initial end of the wire from the plug due to pulling the end of the wire with force, resulting in the lamp socket being unable to be powered on.

[0012] 2. A lamp socket housing provided by the utility model has several extension blocks arranged in the wire installation groove. The gap between two extension blocks forms a conductive insertion and a positioning groove for fixing the wire. One wire is clamped in one positioning groove, which can prevent the wire from being misaligned during assembly, resulting in the wrong installation position of the wire and causing a short circuit of the lamp socket.

[0013] 3. The outer part of the wire of a lamp socket housing provided by the utility model is arc-shaped. To enable the wire and the positioning groove to be fully clamped, the two side surfaces of the positioning groove form arc surfaces for clamping the outer end surface of the wire. To prevent the wire from moving within the arc surfaces, extension convex surfaces are provided at the upper and lower ends of the arc surfaces, and the arc surfaces and the extension convex surfaces form a wavy structure.

[0024] Embodiment

[0025] This embodiment provides a lamp socket housing, a base 1, and a wire installation groove 2 opened on the side of the base 1. One end of the wire passes through the base 1 and is connected to an external plug-in part. The middle end is fixed in the wire installation groove 2, and the other end extends to the outside of the base 1 and is connected to an external part.

[0026] The specific improvement is as follows: As Figure 1 shown, compared with the prior art, the initial end of the wire penetrates into the interior and is connected to the external plug-in part, the middle end is fixed in the wire installation groove 2, and the end extends to the outside of the base 1 and is connected to the external part. After the wire is installed, epoxy resin is poured into the interior of the base 1 to fix the position of the middle end of the wire. When installing the base, it will not cause the separation of the initial end of the wire from the plug due to pulling the end of the wire with force, resulting in the lamp socket being unable to be powered on. Moreover, since the wire is arranged on the side, it can be applicable to the environment where the height of the space for accommodating the lamp socket is insufficient.

[0027] Based on the above embodiments: The base 1 is arranged in an annular structure, and a plurality of extension blocks 3 are arranged in the wire installation groove 2. There are gaps between adjacent extension blocks 3, and positioning grooves 4 for positioning the wire are formed at the gaps.

[0028] The above specific improvement is as follows: As Figure 1 - Figure 2 shown, a plurality of extension blocks 3 are arranged in the wire installation groove 2. The gaps between two extension blocks 3 form conductive inserts and the positioning grooves 4 for fixing the wire. One wire is clamped in one positioning groove 4, which can prevent the wire from being misaligned during assembly, resulting in incorrect wire installation positions and causing a short circuit of the lamp socket.

[0029] Based on the above embodiments: The opposite side surfaces of the positioning groove 4 are arranged in a wavy structure and form arc surfaces 5 that can adapt to the outer end surface of the wire.

[0030] The above specific improvement is as follows: As Figure 2 and Figure 3 shown, the outer part of the wire is circular arc-shaped. To enable the wire and the positioning groove 4 to be fully clamped, arc surfaces 5 for clamping the outer end surface of the wire are formed on both side surfaces of the positioning groove 4. To prevent the wire from moving within the arc surface 5, extension convex surfaces are provided at the upper and lower ends of the arc surface 5, and the arc surface 5 and the extension convex surfaces form a wavy structure.

[0031] Based on the above embodiments: Guide inclined surfaces 6 for guiding the wire to be inserted are arranged at the openings of adjacent extension blocks 3.

[0032] The above specific improvement is as follows: As Figure 3 shown, to guide the wire to be inserted into the positioning groove 4, guide inclined surfaces 6 are provided at the tops of adjacent extension blocks 3. An upward-opening entrance that is convenient for the wire to be inserted is formed between two opposite guide inclined surfaces 6.

[0033] Based on the above embodiments: An extension ring 7 is arranged on the base 1. The extension ring 7 is coaxially arranged with the base 1, and the extension blocks 3 are arranged on the side surface of the extension ring 7.

[0034] Based on the above embodiments: A plurality of reinforcing ribs 8 are further arranged between the base 1 and the extension ring 7. The reinforcing ribs 8 are arranged in a circumferential array with the center of the extension ring 7 as the axis.

[0035] The above specific improvement is as follows: As Figure 2 shown, through the arrangement of the reinforcing ribs 8, they are used to connect the base 1 and the extension ring 7. On the one hand, the strength of the extension ring 7 is increased to avoid its fracture when being squeezed. On the other hand, it is convenient for the base 1 and the extension ring 7 to be integrally injection-molded.

[0036] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
