Detailed implementation manner

[0017] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manner is not a limitation to the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Please refer to Figures 1-4 , the specifically implemented socket with adjustable jack spacing includes a housing 1, a wire 6, a plurality of jack sockets 4, and a spring piece component 5 arranged inside the jack socket 4. A conductive component 2 is provided between the wire 6 and the spring piece component 5 for electrical connection. The housing 1 includes a top cover 1a and a bottom shell 1b. The clearance hole 11 is opened on the top end surface of the top cover 1a, and the conductive component 2 is arranged on the top end surface of the bottom shell 1b; Among them, a plurality of clearance holes 11 are provided on the surface of the housing 1. The clearance holes 11 are distributed in an annular array structure along the center of the housing 1. The jack socket 4 includes a base 41 and a cover plate 42. A plurality of insertion holes 43 extending into the base 41 are opened on the surface of the cover plate 42. The edge of the cover plate 42 extends to both sides of the base 41. The jack socket 4 is movably arranged below the clearance hole 11 through the cover plate 42, and the insertion hole 43 is located inside the clearance hole 11 for swinging.

[0019] Specifically, as Figure 2 shown, the clearance hole 11 is a fan-shaped structure, and inwardly concave chutes 12 are provided below the arc edges on both sides of the clearance hole 11. The side wall of the cover plate 42 is slidably embedded inside the chute 12.

[0020] By providing clearance holes 11 distributed in an annular array structure centered on the surface of the housing 1 and integrating the spring piece component 5 through the jack socket 4, the insertion holes 43 can swing inside the clearance holes 11, realizing the function of adjusting the distance between adjacent two insertion holes 43 while ensuring the power-on stability of the socket.

[0021] In a further scheme, the conductive component 2 includes three conductive rings 21, three lead springs 22 and a mounting part 3, wherein the three conductive rings 21 correspond to the live wire, the neutral wire and the ground wire respectively, the conductive ring 21 is an annular metal part, and the conductive ring 21 is arranged directly below the jack socket 4, one end of the lead spring 22 is electrically connected to the middle part of the corresponding conductive ring 21, and one end of the lead spring 22 is electrically connected to the wire 6.

[0022] Among them, the mounting member 3 is a mounting plate with an annular hollow structure, and a plurality of annular limiting grooves 31 are opened inside the mounting member 3, and the plurality of limiting grooves 31 are distributed in a concentric circle structure. The three conductive rings 21 are respectively annular structures with equidistantly reduced radii, and the three conductive rings 21 are distributed in a concentric circle structure. The corresponding conductive rings 21 are embedded and fixed in the corresponding limiting grooves 31, and the corresponding conductive rings 21 are embedded in the limiting grooves 31.

[0023] The conductive rings 21 of the annular structure are distributed under the jack socket 4, so that when the jack socket 4 moves to adjust the spacing, the spring assembly 5 can keep in contact along the surface of the conductive ring 21, thereby ensuring the continuity and stability of its electrical connection. The material of the mounting plate should preferably be ceramic. Since the mounting plate made of ceramic has good insulation performance, it is not easy to short-circuit between the conductive rings 21. Specific as Figure 3 As shown, one end of the lead spring piece 22 is a sleeve end 222, and the lead spring piece 22 is sleeved on the middle part of the conductive ring 21 through the sleeve end 222. The other end of the lead spring piece 22 is a lead end, and a plurality of openings 32 are provided at the bottom of the mounting member 3, and the lead end extends through the openings 32 to the center of the mounting member 3.

[0024] At the same time, in conjunction with the structure of the above-mentioned conductive component 2, the structure of the spring component 5 is as follows Figure 3 As shown, one end of the spring element assembly 5 is a sliding portion 51, and the cross-section of the sliding portion 51 is a "C"-shaped snap-fit ​​structure. The sliding portion 51 extends to the bottom of the base 41. The spring element assembly 5 is movably snap-fitted to the middle of the conductive ring 21 through the sliding portion 51. The end of the spring element assembly 5 away from the sliding portion 51 is a clip portion 52, and the cross-section of the clip portion 52 is a "Y"-shaped fork groove structure. The clip portion 52 is arranged inside the base 41, and the middle parts of both sides of the clip portion 52 are provided with inwardly bent clamping corners 521. The clip portion 52 and the clamping corners 521 on both sides are vertically symmetrical structures.

[0025] Working process of a power strip with adjustable jack spacing: Insert an external plug into the interior of the base 41 along the upper direction of the insertion hole 43, so that the clamping part 52 of the elastic piece assembly 5 clamps and conducts electricity with the external plug. Then, by pushing the external plug, the jack socket 4 can swing along the center of the housing 1. At this time, the sliding part 51 at the bottom of the elastic piece assembly 5 can slide along the middle part of the conductive ring 21, so that the elastic piece assembly 5 can continuously contact and conduct electricity with the corresponding conductive ring 21. At the same time, the lead elastic piece 22 in the middle of the conductive ring 21 can electrically connect several jack sockets 4 to form a parallel circuit with the wire 6.
