AI Technical Summary
Existing sockets are prone to electric shock accidents when children are in contact, and it is difficult to effectively prevent the risk of electric shock caused by mistaken insertion of objects.
Design a conductive contact piece assembly, including conductive contact piece, conductive shrapnel and contact piece. By independently setting and fixing these components, ensure that elastic feet are arranged on the lower side of the socket hole. When the external plug electrode is inserted, the elastic feet are squeezed to make the contact head and contact piece conduct; when pulled out, the contact head is reset to reduce the risk of electric shock.
It effectively reduces the risk of electric shock in the socket. Even if a child accidentally touches the conductive contact piece close to the socket hole, there will be no electric shock. At the same time, when an object is accidentally inserted, it is difficult to completely squeeze the elastic foot, further reducing the risk of electric shock. In addition, independent arrangement and fixing components reduce mold complexity and process difficulty, saving materials.

Description
Technical Field
[0001] The utility model relates to the technical field of sockets, in particular to a conductive contact piece assembly. Background Art
[0002] A socket is a seat into which one or more circuit wiring can be inserted, through which various wiring can be inserted, so as to facilitate connection with other circuits. A power socket is an electrical device that provides a power interface for household appliances. It is also an electrical accessory that is used more frequently in residential electrical design. It is closely related to people's lives. At present, sockets are generally ordinary sockets, which are generally composed of a shell, a terminal arranged in the shell, and a conductive spring. For children with low safety awareness, they may insert nails, copper wires or other conductive objects into the socket jack out of curiosity, or insert their hands into the socket jack, which can easily cause electric shock accidents. Since sockets can be seen everywhere now, it is difficult to keep children out of touch with these sockets, so the only way to prevent electric shock accidents is to improve the anti-electric shock performance of the socket.
[0003] Based on this, it is necessary to propose a socket that prevents electric shock. Utility Model Content

[0009] When the external plug electrode is inserted, the external plug electrode contacts the clamping portion of the conductive contact sheet, and at the same time, the external plug electrode squeezes the elastic foot of the conductive spring sheet, and the elastic foot moves forward after being squeezed, so that the contact head contacts and conducts with the contact sheet;
[0010] When the external plug electrode is pulled out, the external plug electrode is no longer in contact with the clamping portion of the conductive contact sheet, and the elastic foot is no longer squeezed by the external plug electrode, thereby driving the contact head to reset.

[0016] The utility model is further configured that the elastic foot also includes: a basic extension portion, the basic extension portion extends from the second fixing portion and forms a plurality of bends, and the first extension portion extends from an end portion of the basic extension portion.
[0017] The utility model is further arranged that the contact piece includes: a base; an upper clip extending rearwardly from the base and located above the front side of the contact head of the conductive spring sheet; and a lower clip extending rearwardly from the base and located below the front side of the contact head of the conductive spring sheet; after the elastic foot moves, it enters between the upper clip and the lower clip, stretches the upper clip and the lower clip apart, and achieves contact and conduction with the upper clip and the lower clip.

[0024] After adopting the above technical solution, the beneficial effects of the utility model are as follows: in the utility model, by independently setting the conductive contact piece, the conductive spring piece and the contact piece, since the contact piece is disconnected from the conductive contact piece and the conductive spring piece under normal conditions, even if the user accidentally touches the conductive contact piece close to the socket hole, no electric shock will occur; and since the elastic foot of the conductive spring piece extends to the lower side of the socket hole and is close to the front side of the socket hole, when other objects are mistakenly inserted into the socket hole, the elastic foot cannot be squeezed or it is difficult to completely squeeze the elastic foot, and the conductive spring piece will not contact and conduct with the contact piece, further reducing the risk of electric shock. In addition, the conductive contact piece and the conductive spring piece are independently set and fixed together instead of being integrally formed, which greatly reduces the complexity of the mold, reduces the process difficulty, and saves materials.

[0035] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0036] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
[0037] This embodiment relates to a conductive contact assembly for a socket, referring to Figure 1-Figure 4 , including three parts: a conductive contact sheet 100, a conductive spring sheet 200 and a contact sheet 300.
[0038] The conductive contact 100 includes: a clamping portion 110 located at the lower side of the socket hole and used to contact the external plug electrode 400, and a first fixing portion 120 extending from the clamping portion 110 to the front side. The conductive spring 200 includes: a second fixing portion 210 fixedly connected to the first fixing portion 120 of the conductive contact 100, an elastic foot 220 extending from the second fixing portion 210 and having its end located at the front side, and a contact head 230 arranged at the end of the elastic foot 220. The elastic foot 220 partially extends to the lower side of the socket hole and is close to the front side of the socket hole. The contact piece 300 is arranged separately from the conductive contact 100 and the conductive spring 200, and is located at the front side of the contact head 230 of the conductive spring 200.
[0039] When the external plug electrode 400 is inserted, the external plug electrode 400 contacts the clamping portion 110 of the conductive contact sheet 100, and at the same time, the external plug electrode 400 squeezes the elastic foot 220 of the conductive spring sheet 200, and the elastic foot 220 moves forward after being squeezed, so that the contact head 230 contacts and conducts with the contact sheet 300; when the external plug electrode 400 is pulled out, the external plug electrode 400 no longer contacts the clamping portion 110 of the conductive contact sheet 100, and at the same time, the elastic foot 220 is no longer squeezed by the external plug electrode 400, thereby driving the contact head 230 to reset.
[0040] By independently setting up the conductive contact 100, the conductive spring 200 and the contact piece 300, since the contact piece 300 is disconnected from the conductive contact 100 and the conductive spring 200 under normal conditions, even if the user accidentally touches the conductive contact 100 close to the socket hole, no electric shock will occur; and since the elastic foot 220 of the conductive spring 200 partially extends to the lower side of the socket hole and close to the front side of the socket hole, when other objects (such as needles, sharp blades, etc.) are mistakenly inserted into the socket hole, the elastic foot 220 cannot be squeezed or it is difficult to completely squeeze the elastic foot 220, and the conductive spring 200 will not contact and conduct with the contact piece 300, further reducing the risk of electric shock. In addition, the conductive contact 100 and the conductive spring 200 are independently set and fixed together instead of being integrally formed, which greatly reduces the complexity of the mold, reduces the process difficulty, and saves materials.
[0041] Existing sockets will have power loss in standby mode, which increases carbon emissions. However, in the socket using the conductive contact assembly of this solution, since the contact sheet 300 is disconnected from the conductive spring sheet 200 under normal conditions, that is, when the socket using this solution is not plugged in, it is in an open circuit state, and will not consume power, effectively reducing carbon emissions.
[0042] In this embodiment, the material of the conductive spring 200 is phosphor copper, and the materials of the conductive contact 100 and the contact piece 300 are both brass. Phosphor copper has a better rebound effect than brass, and can still maintain good elasticity after 5,000 or even 10,000 tests, but the cost of using phosphor copper is much higher than that of using brass, so phosphor copper is only used in the conductive spring 200 that requires a better rebound effect. If the conductive contact 100 and the conductive spring 200 are all made of brass, although the price is low, after repeated use, there is a problem that the rebound elasticity of the conductive spring 200 is reduced, resulting in poor contact; if the conductive contact 100 and the conductive spring 200 are all made of phosphor copper, although the performance is superior, the cost is too high. This solution solves this problem by using phosphor copper in the key component-the conductive spring 200.
[0043] More specifically, the material of the conductive spring 200 is C5191 phosphor copper.
[0044] Reference Figure 1-Figure 5 The elastic foot 220 includes a first extending portion 221 , a second extending portion 222 and a third extending portion 223 .
[0045] The first extension part 221 extends obliquely upward from the rear side of the second fixing part 210; the second extension part 222 extends from the end of the first extension part 221 and bends downward; the third extension part 223 extends from the end of the second extension part 222 and extends downward and forward. The elastic foot 220 is used for the external plug electrode 400 to be pressed at the second extension part 222, that is, the second extension part 222 partially extends to the lower side of the socket hole and close to the front side of the socket hole. The contact head 230 is arranged at the end of the third extension part 223.
[0046] On the basis of the above, in order to further improve the elasticity of the elastic foot 220, refer to Figure 4-Figure 5 The elastic foot 220 further includes a base extension portion 224 . The base extension portion 224 extends from the second fixing portion 210 and forms a plurality of bends. The first extension portion 221 extends from an end of the base extension portion 224 .
[0047] Reference Figure 1-Figure 4 The contact piece 300 includes: a base 310; an upper clip 320 extending from the base 310 to the rear side and located above the front side of the contact head 230 of the conductive spring piece 200; and a lower clip 330 extending from the base 310 to the rear side and located below the front side of the contact head 230 of the conductive spring piece 200. After being squeezed and moved, the elastic foot 220 enters between the upper clip 320 and the lower clip 330, stretching the upper clip 320 and the lower clip 330 apart, and achieving contact and conduction with the upper clip 320 and the lower clip 330. The contact piece 300 is configured to have an upper clip 320 and a lower clip 330, and the distance between the upper clip 320 and the lower clip 330 is smaller than the thickness of the contact head 230. With this configuration, when the contact head 230 enters between the upper clip 320 and the lower clip 330 along the movement path, the upper clip 320 and the lower clip 330 will inevitably be stretched apart. After being stretched apart, the upper clip 320 and the lower clip 330 will be clamped on both sides of the contact head 230 under the action of the rebound force, thereby ensuring good contact between the contact piece 300 and the conductive spring sheet 200. In order to make the contact head 230 enter between the upper clip 320 and the lower clip 330 more smoothly, the upper clip 320 and the lower clip 330 have a first guide surface 340 open outward at one end close to the elastic foot 220.
[0048] Reference Figure 1-Figure 4 The clamping portion 110 of the conductive contact sheet 100 is in a sheet shape and folded into a U shape, and the first fixing portion 120 is in a sheet shape. The upper end of the clamping portion 110 has a second guide surface 111 open to the outside. The function of the second guide surface 111 is to make the external plug electrode 400 enter the clamping portion 110 more smoothly.
[0049] Reference Figure 1-Figure 4The first fixing portion 120 of the conductive contact piece 100 is provided with a first rivet hole 121, and the second fixing portion 210 of the conductive spring piece 200 is provided with a corresponding second rivet hole 211, and the second fixing portion 210 is fixed to the first fixing portion 120 by riveting. Specifically in this embodiment, the first fixing portion 120 of the conductive contact piece 100 is provided with two first rivet holes 121, and the second fixing portion 210 of the conductive spring piece 200 is correspondingly provided with two second rivet holes 211, and the riveted connection at two points is more stable.
[0050] The working principle of the utility model is as follows: by independently setting up the conductive contact 100, the conductive spring 200 and the contact piece 300, since the contact piece 300 is disconnected from the conductive contact 100 and the conductive spring 200 under normal conditions, even if the user accidentally touches the conductive contact 100 close to the socket hole, no electric shock will occur; and since the elastic foot 220 of the conductive spring 200 partially extends to the lower side of the socket hole and close to the front side of the socket hole, when other objects (such as needles, sharp blades, etc.) are mistakenly inserted into the socket hole, the elastic foot 220 cannot be squeezed or it is difficult to completely squeeze the elastic foot 220, and the conductive spring 200 will not contact and conduct with the contact piece 300, further reducing the risk of electric shock. In addition, the conductive contact 100 and the conductive spring 200 are independently set and fixed together instead of being integrally formed, which greatly reduces the complexity of the mold, reduces the process difficulty, and saves materials.
[0051] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
