[0024] Embodiment

[0025] This embodiment provides a lamp socket filling structure, including a hollow base 1 and a filling plug 11 arranged in the base 1. A perforation 12 for the wire to pass through is provided in the filling plug 11, and a wire installation groove 2 is arranged 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. A receiving cavity 13 for fixing the wire with filling epoxy resin is arranged between the base 1 and the filling plug 11.

[0026] The above specific improvement is as follows: Such as Figure 1 And Figure 3As shown, compared with the prior art, during the assembly process, it is necessary to first install the filling block into the base 1, then pass the wire through the through-hole 12 on the filling plug 11 and connect it to the plug-in connector. The middle position of the wire is fixed on the wire installation groove 2. Finally, epoxy resin is filled into the accommodating cavity 13, so that the wire can be quickly fixed. In this way, during the later assembly process, even if the end of the wire is pulled forcefully, the middle part is fixed, and the position where the wire is connected to the plug-in connector will not be separated from the plug-in connector due to the pulling force.

[0027] Based on the above embodiment: The base 1 is arranged in a ring structure, the base 1 and the filling plug 11 are coaxially arranged, and a plurality of support blocks 14 for supporting the filling plug 11 are arranged on the inner side wall of the base 1. The support blocks 14 are arranged in a circumferential array with the axis of the base 1 as the center, and the upper end surfaces of the support blocks 14 are in contact with the lower end surface of the filling plug 11.

[0028] Based on the above embodiment: A plurality of clamping blocks 15 for guiding the clamping of the filling plug 11 are further arranged on the inner side surface of the base 1, and a guiding inclined surface 16 is arranged on the clamping blocks 15.

[0029] The above specific improvement is: As Figure 3 shown, when installing the filling plug 11 and the base 1, it is necessary to install the filling plug 11 into the interior of the base 1 along the guiding inclined surface 6 of the clamping block 15. The clamping block 15 and the support block 14 respectively limit the upper and lower ends of the filling plug 11, so as to prevent the filling plug 11 from detaching from the base 1. After installing the filling plug 11, install the wire. After the wire is inserted into the through-hole 12 in sequence, epoxy resin is filled into the accommodating cavity 13, and the gap between the filling plug 11 and the inner wall of the base 1 is filled, and finally the position of the filling plug 11 is fixed.

[0030] Based on the above embodiment: The base 1 is arranged in a ring 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.

[0031] The above specific improvement is: As Figure 1 - Figure 2 shown, a plurality of extension blocks 33 are arranged in the wire installation groove 22. The gaps existing between the two extension blocks 33 form a conductive insertion and a positioning groove 44 for fixing the wire. One wire is clamped in one positioning groove 44, which can prevent the wire from being misaligned during assembly, resulting in incorrect wire installation position and causing a short circuit of the lamp socket.

[0032] Based on the above embodiment: The opposite side surfaces of the positioning groove 4 are arranged in a wavy structure and form an arc surface 5 that can adapt to the outer end surface of the wire.

[0033] The above specific improvement is: As Figure 2 and Figure 3As shown, the outer part of the wire is arc-shaped. To enable the wire and the positioning groove 44 to be fully clamped, arc-shaped surfaces 55 for clamping the outer end surface of the wire are formed on both sides of the positioning groove 44. To prevent the wire from moving within the arc-shaped surfaces 55, extension convex surfaces are provided at the upper and lower ends of the arc-shaped surfaces 55, and the arc-shaped surfaces 55 and the extension convex surfaces form a wavy structure.

[0034] Based on the above embodiment: A guiding inclined surface 6 for guiding the insertion of the wire is provided at the opening of adjacent extension blocks 3.

[0035] The above specific improvement is as follows: As Figure 3 shown, to guide the wire to be inserted into the positioning groove 44, guiding inclined surfaces 66 are provided at the tops of adjacent extension blocks 33, and an upward-opening entrance that facilitates the insertion of the wire is formed between two opposite guiding inclined surfaces 66.

[0036] Based on the above embodiment: The number of the perforations 12 is 4 - 12.

[0037] 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 list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
