[0050] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0051] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0052] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0053] On the one hand, combined with Figure 1 and Figure 2As shown, this embodiment provides a socket structure 10 , which includes: a substrate 1 , and a first conductive sheet 2 , a second conductive sheet 3 , and a third conductive sheet 4 connected to the substrate 1 .

[0054] At least one of the second conductive sheet 3 and the third conductive sheet 4 is a U-shaped structure 5, and the opening of the U-shaped structure 5 is directed to the first conductive sheet 2; the U-shaped structure 5 includes a supporting portion 51, an inclined portion 52, an arc portion 53 and a clamping portion 54 connected in sequence, the inclined portion 52 is inclined along the supporting portion 51 toward the clamping portion 54, and the arc portion 53 is connected between the inclined portion 52 and the clamping portion 54.

[0055] A first clamping groove 6 is provided between the second conductive sheet 3 and the third conductive sheet 4 , and the clamping portion 54 is formed as at least one of two side walls of the first clamping groove 6 .

[0056] The socket structure 10 of the present embodiment comprises a substrate 1, a first conductive sheet 2, a second conductive sheet 3 and a third conductive sheet 4, wherein the three conductive sheets are respectively connected to the substrate 1, and at least one of the second conductive sheet 3 and the third conductive sheet 4 is designed as a U-shaped structure 5, wherein the U-shaped structure 5 comprises a supporting portion 51, an inclined portion 52, an arc portion 53 and a clamping portion 54. When the plug member is inserted into the first clamping groove 6, the clamping portion 54, the arc portion 53, the inclined portion 52 and the supporting portion 51 can all be elastically deformed, and the deformation is shared in multiple sections to avoid excessive deformation at a single position and damage to the elastic recovery ability of the structure, thereby ensuring that the second conductive sheet 3 or the third conductive sheet 4 has a more stable clamping force to avoid problems such as loosening and poor contact of the plug.

[0057] Exemplarily, the second conductive sheet 3 is the above-mentioned U-shaped structure 5, and the third conductive sheet 4 is other structures (such as a single spring sheet structure, a stacked sheet structure, etc.); or, the third conductive sheet 4 is the above-mentioned U-shaped structure 5, and the second conductive sheet 3 is other structures; alternatively, the second conductive sheet 3 and the third conductive sheet 4 are respectively the above-mentioned U-shaped structures 5.

[0058] The U-shaped structure 5 in this embodiment is formed by connecting the clamping part 54, the arc part 53, the inclined part 52 and the supporting part 51 in sequence. Compared with the traditional horseshoe U-shape, the deformation will not be concentrated on the arc bend, but the deformation will be dispersed to the clamping part 54, the arc part 53, the inclined part 52 and the supporting part 51. When the latch member in the first clamping groove 6 squeezes the clamping part 54, each part will undergo elastic deformation, and the amount of elastic deformation is less than its own elastic limit. Even in the face of a large number of deformation times and a long deformation time, the clamping part 54, the arc part 53, the inclined part 52 and the supporting part 51 can maintain good elastic recovery ability and can return to the initial state after the squeezing force disappears, thereby maintaining good elastic clamping of the latch member.

[0059] Combination Figure 2As shown, in some embodiments, the central angle of the arc portion 53 is a, where 90°<a<180°. Through the above arrangement, when the U-shaped structure 5 undergoes elastic deformation, the elastic force of the arc portion 53 can be transmitted to the inclined portion 52, and then transmitted to the supporting portion 51 through the inclined portion 52, thereby achieving dispersion of the deformation amount.

[0060] Exemplarily, the value of the central angle a is, for example, 90°, 91°, 95°, 100°, 105°, 120°, 130°, 140°, 150°, 160°, 170°, 175°, 179°, etc.

[0061] Combination Figure 2 As shown, in some embodiments, a second clamping groove 7 is provided between the end of the clamping portion 54 and the first conductive sheet 2. The end of the support portion of the U-shaped structure 5 and the first conductive sheet 2 enclose the second clamping groove 7, which can improve the compatibility of the socket structure 10 with plugs of different specifications.

[0062] In some possible implementations, the first clamping groove 6 is used to clamp a cylindrical plug, and the second clamping groove 7 is used to clamp a parallel flat plug.

[0065] A first clamping groove 6 is formed on the outer side of the first conductive sheet 2 by two clamping portions 54 arranged in parallel and spaced apart.

[0067] The first arc-shaped groove structure 341 of the second conductive sheet 3 and the second arc-shaped groove structure 441 on the third conductive sheet 4 can be used to form a first clamping groove 6 that is approximately annular, thereby clamping the cylindrical plug.

[0068] Combination Figure 4 As shown, in some embodiments, the first conductive sheet 2 is connected to the first edge 101 of the substrate 1, the support portion 51 of the second conductive sheet 3 is connected to the second edge 102 of the substrate 1, the support portion 51 of the third conductive sheet 4 is connected to the third edge 103 of the substrate 1, and the second edge 102 and the third edge 103 are respectively located at both ends of the first edge 101; the first conductive sheet 2 is located between the two support portions 51.

[0069] The supporting portion 51 , inclined portion 52 , arc portion 53 and clamping portion 54 of the second conductive sheet 3 and the third conductive sheet 4 extend to the outer side of the first conductive sheet 2 away from the substrate 1 , so that the first clamping groove 6 is located outside the substrate 1 .

[0070] Through the above arrangement, the working surfaces of the first conductive sheet 2, the second conductive sheet 3 and the third conductive sheet 4, that is, the multiple clamping grooves surrounded by the three are all located on the outside of the substrate 1. When the latch is inserted in the clamping groove, it will not be interfered by the substrate 1, so that the socket structure 10 can adapt to latches of different lengths.

The second clamping groove 7 is formed by the end surface of the first clamping portion 5434, the end of the second clamping portion 5444 and the outer side surface of the first conductive sheet 2.

[0075] Combination Figure 5 As shown, in some embodiments, the portion of the first conductive sheet 2 corresponding to the second clamping groove 7 is provided with an elastic protrusion structure 21. The elastic protrusion structure 21 can improve the elastic clamping performance of the first conductive sheet 2 and improve the stability of the electrical contact between the first conductive sheet 2 and the plug member.
