[0019] This utility model provides a dynamic rebound socket and receptacle. The dynamic rebound socket consists of two opposing first spring pieces forming a clamping space. Extension sections extend from both ends of the first spring pieces and are folded back through bending sections, creating a deformation space between the extension sections and the bending sections. When a pin is inserted, the first spring pieces elastically deform outward under force. This deformation can be partially released into the deformation space. When the pin is pulled out, the deformation space provides sufficient rebound stroke for the first spring pieces, allowing them to return to their initial position. This utility model, by providing deformation spaces enclosed by extension sections and bending sections on both sides of the protrusion, allows the first spring pieces to obtain greater elastic deformation during pin insertion and removal, thus providing better rebound capability after the pin is removed. This effectively avoids the problem of non-rebound caused by limited deformation in existing sockets, ensures the stability of insertion and removal force, reduces temperature rise caused by poor contact, and improves the reliability and lifespan of the receptacle.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of socket technology, and in particular to a dynamic rebound sleeve and socket. Background Technology
[0002] As a common electrical connection device, sockets are widely used in homes, offices, and industrial locations. Sockets typically have a socket sleeve inside, usually made of a conductive metal sheet, installed within the socket housing. Its function is to ensure reliable electrical contact when the user inserts the plug, and to spring back to its initial shape after the plug is removed, thus guaranteeing contact reliability and lifespan during repeated insertions and removals.
[0003] In existing technologies, sockets are mostly made of materials such as copper or phosphor bronze through stamping and are fixed by a limiting structure inside the outer shell. A common socket structure has relatively short contact portions between the two ends of the socket and the pin, relying on plastic supports inside the socket shell for positioning and constraint. While this design provides basic fixation, it has the following shortcomings: First, the deformation space is limited. The metal plate of the socket mainly relies on elastic deformation to achieve clamping when the plug is inserted. However, because the two ends of the socket are tightly constrained by the plastic parts, its deformable space is small.
[0004] Second, insufficient rebound performance. During insertion and removal, the metal plate of the socket is subjected to external force for a long time, which will cause plastic deformation. Due to the lack of sufficient elastic buffer stroke, the socket often cannot fully rebound after the plug is pulled out, resulting in a decrease in clamping force.
[0005] Third, the insertion and extraction force is unstable. After repeated insertion and extraction, the elasticity of the socket gradually weakens, which can easily lead to problems such as loose or poor contact of the plug, affecting safety during use.
[0006] Therefore, how to improve the socket structure to provide greater deformation space and enhance the springback capability of the socket while ensuring reliable fixation has become a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0007] The purpose of this invention is to provide a dynamic rebound sleeve and socket to solve the aforementioned technical problems in the prior art.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0023] refer to Figures 1 to 13 As shown, the embodiments of this application will be described in detail below.
[0024] In one embodiment, such as Figures 1 to 6 As shown, the dynamic rebound sleeve 02 in this embodiment includes a convex portion 10 and an enclosing portion 20. The convex portion 10 includes two opposing first spring pieces 11, forming a first clamping space S1 between the two first spring pieces 11 for clamping the first pin 61. The enclosing portion 20 includes two extension segments 21 and two bending segments 22. Each extension segment 21 extends outward from one end of a first spring piece 11 along a first direction D1, and each bending segment 22 folds back from an extension segment 21 towards a second direction D2. The first direction D1 is opposite to the second direction D2, so that on both sides of the convex portion 10, each extension segment 21 and bending segment 22 forms a deformation space S0.
[0025] The dynamic rebound socket provided in this embodiment consists of two opposing first spring pieces forming a clamping space. Extension sections extend from both ends of the first spring pieces and fold back through bending sections, creating a deformation space between the extension sections and the bending sections. When the pin is inserted, the first spring pieces elastically deform outward under force, and this deformation can be partially released into the deformation space. When the pin is pulled out, the deformation space provides sufficient rebound stroke for the first spring pieces, allowing them to return to their initial position. By providing a socket with a deformation space enclosed by extension sections and bending sections on both sides of the convex portion, the first spring pieces can obtain greater elastic deformation during pin insertion and removal, thus exhibiting better rebound capability after the pin is removed. This effectively avoids the problem of non-rebound caused by limited deformation in existing sockets, ensures the stability of insertion and removal forces, reduces temperature rise caused by poor contact, and improves the reliability and lifespan of the socket.
[0026] Alternatively, in one embodiment, such as Figure 3 and Figure 4 As shown, in addition to the extension section 21 and the bending section 22, the surrounding portion 20 also includes a connecting section 23. The connecting section 23 connects the two bending sections 22 to each other, and the surrounding portion 20 forms a deformation space S0 surrounding the convex portion 10. The connecting section 23 makes the entire surrounding portion form a structure surrounding the convex portion 10, thereby placing the convex portion 10 within a deformation space S0 defined by the surrounding portion 20. When the first spring piece 11 deforms as the pin is inserted, the deformation can expand outwards and be released into the space enclosed by the surrounding portion 20, ensuring sufficient deformation stroke.
[0027] The sleeve provided in this embodiment has a connecting section in the surrounding part to connect two bent sections, so that the surrounding part forms a continuous deformation space around the convex part, thereby improving the overall structural stability of the sleeve and providing a more sufficient and uniform space release for the elastic deformation of the first spring piece, ensuring the rebound performance after the pin is pulled out, and effectively improving the stability of the insertion and extraction force and the service life.
[0028] Alternatively, in one embodiment, such as Figure 6 As shown, the socket also includes a plug portion 40, which is formed by the connecting section 23 extending in the opposite direction D4 of the protrusion of the convex portion 10, for connection with a power terminal. When the socket is fitted into the socket housing, the plug portion 40 can be inserted into the power terminal or crimped / soldered with a wire, thereby reliably connecting the socket to an external power source.
[0029] The socket provided in this embodiment extends on the connecting section to form a plug-in portion, enabling the socket to be directly connected to the power terminal. This not only simplifies the assembly structure but also improves the reliability and stability of the electrical connection, thereby ensuring the safety and conductivity of the socket during long-term use.
[0030] Optionally, in one embodiment, reference continues to be made to... Figure 6 The insertion portion 40 extends from the connecting section 23 and includes a guide section 41 and a insert 42. The guide section 41 is located between the connecting section 23 and the insert 42, extending in a first direction D1 to serve as a transition and guide. The insert 42 continues to extend from the guide section 41 and in the opposite direction D4 to the protrusion of the convex portion 10, and its surface is formed with a serrated texture. The guide section 41 guides the insert 42 to be located in the middle of the socket. During assembly or wire crimping, it stably enters the power terminal, and the serrated texture of the insert 42 enhances friction and improves the fixing effect.
[0031] The socket provided in this embodiment has a guide section and a insert at the insertion part. The guide section guides the insert to the middle of the socket and forms a serrated pattern on the surface of the insert. This not only makes the socket more stable during assembly and improves the convenience of docking with the power terminal, but also enhances the fixing effect and electrical contact reliability of the insertion part, thereby effectively ensuring the conductivity and long-term reliability of the socket.
[0032] Alternatively, in one embodiment, such as Figure 4 and Figure 6 As shown, the socket also includes a fixing part 50, which is formed by extending the bent section 22. Specifically, it includes a plurality of limiting protrusions 51 extending in the opposite direction D4 from the bent section 22 to the protrusion of the convex portion 10. When the socket is fitted into the socket housing, the limiting protrusions 51 can be embedded in the mating groove or positioning hole of the housing, thereby limiting and fixing the socket and preventing the socket from shifting position during insertion and removal.
[0033] Alternatively, in one embodiment, such as Figures 7 to 9 As shown, the socket in this embodiment also includes a second spring piece 30, which is formed by the connecting segment 23 extending in the direction D3 of the protrusion of the convex portion 10 and arranged opposite to the convex portion 10, so that a second clamping space S2 is formed between the second spring piece 30 and the convex portion 10 for clamping the second pin 62. When the second pin 62 is inserted, it can be inserted and clamped by the second spring piece 30 and the convex portion 10, so as to achieve reliable electrical contact with the socket.
[0034] The socket provided in this embodiment extends to form a second spring piece on the connecting section and forms a second clamping space between it and the protrusion, so that the socket can additionally clamp a second pin, achieving compatibility with different plug pins, while ensuring that each pin has independent and stable electrical contact, thereby improving the applicability and conductivity reliability of the socket.
[0035] Alternatively, in one embodiment, such as Figure 7 and Figure 8As shown, the second spring 30 consists of two segments extending in different directions. The first segment 31 extends obliquely along a first direction D1, and the second segment 32 extends obliquely along a second direction D2, which is opposite to it. Thus, the two segments form a clamping position at their junction. The second pin 62 is a flat pin. When the flat second pin 62 is inserted, its edge can abut against the second spring 30 at the junction of the first segment 31 and the second segment 32, and during the insertion and removal process, it compresses the second spring 30 to produce elastic deformation, thereby obtaining a stable clamping contact.
[0036] The sleeve provided in this embodiment has a second spring piece designed as a first segment and a second segment inclined in opposite directions, and the flat pin contacts the second spring piece at the junction of the two segments. This not only achieves stable clamping and reliable conductivity of the flat pin, but also makes the pin and the sleeve have a larger contact area, reducing temperature rise.
[0037] In existing technologies, such as Figure 10 As shown, the protruding bulge 11' of the insert is arc-shaped and mates with the circular pin 61'. Generally, there is two-point contact, as shown in contact points A' and B' in the figure. The contact area is small, resulting in a relatively high temperature rise. Optionally, in one embodiment, as... Figure 11 and Figure 12 As shown, in this embodiment, the first spring piece 11 includes a contact segment 111 and a contact segment 112. Each contact segment 111 (112) is adapted to the shape of the first pin 61, so that each contact segment 111 (112) has at least one contact point with the first pin 61, and each first spring piece 11 has at least two contact points with the first pin 61. By increasing the contact points between the pin and the sleeve, the contact area between the pin and the sleeve is increased, effectively reducing the temperature rise.
[0038] Further, optional, refer to Figure 11 and Figure 12 As shown, the first pin 61 is a circular pin, and the contact segments 111 and 112 of the first spring piece 11 are arranged in a V-shape. The contact segments 111 and 112 of each first spring piece 11 are tangent to the circular pin, thus forming a four-point contact between the sleeve and the pin. Figure 11 The contact points A, B, C, and D are shown.
[0039] The socket provided in this embodiment can simultaneously contact two contact segments when the first pin is inserted into the clamping space. Furthermore, the two contact segments are arranged in a V-shape, and the outer surface of the first pin can make tangential contact with the two arms of the V-shape respectively, thereby maintaining a stable multi-point contact relationship during insertion and removal, reducing temperature rise, ensuring uniform distribution of clamping force, and improving the stability of electrical contact and the smoothness of insertion and removal.
[0040] In one embodiment, such as Figure 13 As shown, the socket includes a housing 01 and a socket 02 installed inside the housing 01 for electrical contact with the plug pin. The socket 02 is any of the aforementioned dynamic rebound sockets.
