[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] See also Figures 1 to 6 An embodiment of the utility model provides a lamp holder, including an end cap 100 and a conductive member 200, wherein the end cap 100 has a barrel wall 110 and an end wall 120, the conductive member 200 is riveted and fixed on the end wall 120, and its end has a flange 211 arranged along the circumferential direction. The end cap 100 has a first pad 300 inside that is attached to the inner surface of the end wall 120, the flange 211 and the end wall 120 jointly clamp and fix the first pad 300, and the first pad 300 has a base layer 310 and a metal film layer 330, wherein the metal film layer 330 is in contact with the flange 211 and is energized, and a wire 400 is welded thereto. In this embodiment, by arranging the first pad 300 in the lamp holder, the wire 400 is conveniently fixed, and the metal film layer 330 ensures that the wire 400 has a good electrical connection with the conductive member 200.

[0030] Typically, the end cap 100 can be made of plastic or metal, and the end wall 120 is provided with a central hole for allowing the conductive member 200 to pass through; the wire 400 is used to connect with the driving component or the light-emitting component in the lamp. The flange can be a flange structure formed by punching the end of the conductive member 200 with a jig; one end of the wire 400 can be punched under the flange 211 and / or fixed by soldering.

[0031] In one embodiment, the base layer 310 of the first pad 300 is made of an insulating material, such as plastic; the metal film layer 330 may be a copper film layer. The base layer 310 has a first surface and a second surface opposite to each other along the axial direction, wherein the first surface is in contact with the end wall 120, and the second surface is covered with the metal film layer 330, and the metal film layer 330 is isolated from contact with the end cover 100 to prevent the two from contacting and conducting electricity.

[0032] In another embodiment, the base layer 310 is made of a metal material, such as an aluminum material, and an insulating layer 320 and a metal film layer 330 are sequentially covered on the second surface of the base layer 310. The base layer 310 and the metal film layer 330 are isolated by the insulating layer 320 to avoid mutual conduction, thereby improving the safety of the lamp holder.

[0033] See also Figure 2 , 6 In the illustrated embodiment, the inner surface of the end wall 120 has a first positioning groove 130 that cooperates with the first pad 300 and is used to fix the first pad 300. Specifically, the first pad 300 is a circular ring structure with a center hole, and the first positioning groove 130 is an annular groove arranged around the center hole of the end wall 120.

[0034] See also Figure 3 , 5 The outer wall of the end cover 100 is provided with a second pad 500 that is close to the outer surface of the end wall 120, which is conducive to riveting the conductive member 200 to the end cover 100, and the riveting effect is good. The second pad 500 can be a circular ring structure, and the second positioning groove 140 is an annular groove arranged around the center hole of the end wall 120. The conductive member 200 passes through the second pad 500, the end wall 120 and the first pad 300 in sequence during the riveting process.

[0035] The conductive member 200 is a hollow columnar structure, and has a first end 210 and a second end 220 opposite to each other in the axial direction, wherein the first end 210 is open and provided with a flange 211, and is located inside the end cover 100, and the second end 220 is closed and located outside the end cover 100, and is used to connect to the socket. The conductive member 200 also has an expanded diameter portion 230 located outside the end cover 100, and the expanded diameter portion 230 and the end wall 120 clamp and fix the second pad 500.

[0036] Furthermore, the outer surface of the end wall 120 is sunken to form a second positioning groove 140 that matches the second pad 500. The second pad 500 can be completely accommodated in the second positioning groove 140, and the outer surface of the second pad 500 is flush with the outer surface of the end wall 120, which makes the overall structure of the end cover 100 compact and aesthetically pleasing, and avoids interference with the matching of the lamp cap and the lamp holder. Considering safety, the second pad 500 is usually made of insulating material to play an insulating role between the conductive member 200 and the end wall 120.

[0037] In the utility model, a first pad 300 is arranged in the end cover 100 of the lamp holder. The metal film layer 330 on the first pad 300 is conducive to fixing the wire 400 and ensuring good conductivity between the wire 400 and the conductive member 200 .

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
