In the following, it will be combined with... Figures 1 to 8 The principles of this disclosure are described.

[0027] Figure 1 A perspective view of a grounding plate 100 for a socket 1000 according to some embodiments of the present disclosure is shown. Figure 2 It shows Figure 1 The diagram shows a perspective view of the grounding plate 100 and two grounding elements 300 of a socket 1000 according to some embodiments of the present disclosure. The grounding plate 100 and the two grounding elements 300 assembled together are particularly suitable for sockets with two outlets. Figure 3 and Figure 4Perspective views of a socket 1000 according to some embodiments of the present disclosure, viewed from different angles, are shown. The socket 1000 includes... Figure 2 The grounding plate 100 and two grounding components 300 are shown. For ease of explanation, Figure 4 The base of socket 1000 is not shown in the diagram. Figure 5 It shows Figure 4 The diagram shows a side view of socket 1000. Figure 6 It shows along Figure 5 The cross-sectional view shown is taken by the section line AA. Figure 7 It shows Figure 6 Enlarged view of point B in the image. Figure 8 It shows Figure 1 A three-dimensional schematic diagram of a variant embodiment of the grounding plate 100 shown.

[0028] See Figure 1 The grounding piece 100 can be made of a metal material with good conductivity and includes a base 10, a first tear 11, and a second tear 12. The first tear 11 and the second tear 12 are located in the middle of the base 10 and are formed by cutting from the base 10. The first tear 11 and the second tear 12 are opposite to each other and extend elastically to the same side of the base 10. The first tear 11 and the second tear 12 are equivalent to two clamping springs (also called grounding springs), forming a clamping space 13 between the first tear 11 and the second tear 12. See also... Figure 2 The protruding portions of the two grounding components 300 (the protruding portions are, for example, Figure 2 The U-shaped grounding part 34 shown can be inserted into the clamping space 13 to be clamped by the first tear part 11 and the second tear part 12, so that the two grounding parts 300 are grounded through the same grounding piece 100.

[0029] According to the grounding piece 100 provided in the embodiments of this disclosure, a first tear 11 and a second tear 12 are obtained by cutting the middle position of the base 10. The first tear 11 and the second tear 12 are connected to the two grounding members 300 by clamping the U-shaped grounding portions 34 of the two grounding members 300. Compared with forming a protrusion by folding the middle part of the grounding piece 100 and clamping the protrusion between the two grounding members 300 to achieve the connection between the grounding piece and the two grounding members, the grounding piece 100 provided in the embodiments of this disclosure requires less material, which is beneficial to saving costs. Moreover, the structure of the grounding piece 100 is simple and reliable.

[0030] See also Figure 1In some embodiments, the base 10 is generally elongated, and the elongated base 10 is not limited to extending in a single plane. The first tear 11 includes a bottom connected to the base 10 and a free end opposite to the bottom, as well as two opposing sides located between the bottom and the free end. The structure of the second tear 12 is similar to that of the first tear 11. The second tear 12 includes a bottom connected to the base 10 and a free end opposite to the bottom, as well as two opposing sides located between the bottom and the free end.

[0031] See also Figure 1 In some embodiments, a rectangular hole 101 is formed in the middle of the base 10 by cutting. The rectangular hole 101 includes a first side and a second side opposite to each other in the length direction of the grounding piece 100, and a third side and a fourth side opposite to each other in the width direction of the grounding piece 100. The bottom of the first tear 11 is connected to the first side of the rectangular hole 101, that is, the first tear 11 extends from the first side of the rectangular hole 101. The bottom of the second tear 12 is connected to the second side of the rectangular hole 101, that is, the second tear 12 extends from the second side of the rectangular hole 101. It can be understood that one side of the first tear 11 and one side of the second tear 12 correspond to the third side of the rectangular hole 101, and the other side of the first tear 11 and the other side of the second tear 12 correspond to the fourth side of the rectangular hole 101.

[0032] The following is combined with Figure 1 An exemplary manufacturing process for the grounding piece 100 is described below.

[0033] When manufacturing the grounding piece 100, a long strip of sheet metal can first be stamped from a metal sheet. Simultaneously, gaps are cut between the two sides of the first tear 11 and the base 10, between the two sides of the second tear 12 and the base 10, and between the free ends of the first tear 11 and the second tear 12. Then, the first tear 11 and the second tear 12 are bent so that the first tear 11 extends from one side of the base 10, and the second tear 12 extends from one side of the base 10. It is understood that the contours of the free ends of the first tear 11 and the second tear 12 match.

[0034] Figure 2An exemplary structure of two grounding elements 300 cooperating with a grounding plate 100 is shown. As shown, each grounding element 300 may include a connecting bridge 33, a first grounding spring 31, a U-shaped grounding portion 34, and a second grounding spring 32. The first grounding spring 31 extends from a first end of the connecting bridge 33 toward a first side of the connecting bridge 33. The U-shaped grounding portion 34 includes opposing first side plates 341 and second side plates 342, with the first side plate 341 extending from a second end of the connecting bridge 33 toward a second side of the connecting bridge 33. The opening of the U-shaped grounding portion 34 faces the first side of the connecting bridge 33. The second grounding spring 32 extends from the second side plate 342 toward the first side of the connecting bridge 33, with the second grounding spring 32 opposite to the first grounding spring 31. The U-shaped grounding portions 34 of the two grounding elements 300 may be connected to each other in any suitable manner and are adapted to be inserted into the clamping space 13 of the grounding plate 100.

[0035] It is understood that the structure of each of the two grounding components 300 is not limited to the example above. As long as each grounding component 300 has a protruding portion equivalent to the U-shaped grounding portion 34, when the two grounding components 300 are fixed together, the protruding portions of the two grounding components 300 can be inserted into the clamping space 13 and clamped by the first tear portion 11 and the second tear portion 12.

[0036] See Figures 3 to 7 The grounding plate 100 and two grounding elements 300 are adapted to be installed inside the housing of a socket 1000 according to an embodiment of the present disclosure. The socket 1000 is, for example, a Schuko socket. The housing of the socket 1000 includes, for example, a faceplate 500 and a base (not shown). The faceplate 500 is provided with two sockets 51, and the bottom wall of each socket 51 is provided with slots 511 and slots 512 for engaging two pins (not shown) of a plug (e.g., a Schuko plug), one of which is connected to the live wire and the other to the neutral wire.

[0037] Each socket 51 has two openings 513 on its peripheral wall, spaced 180 degrees apart. The connecting bridge 33 of each grounding element 300 is located between the faceplate 500 and the base of the socket 1000, and the connecting bridge 33 corresponds to the bottom wall of the corresponding socket 51. Each grounding element 300 has two grounding contacts (first grounding contact 31 and second grounding contact 32) with portions 311 extending into the corresponding socket 51 through the two openings 513. When a plug is inserted into the corresponding socket 51, the two grounding contacts of the plug and the portions 311 of the two grounding contacts of the corresponding grounding element 300 (see...) Figure 6 The plug is grounded by connecting the grounding component 300 and the grounding plate 100.

[0038] The socket may also include a cover 200 located between the faceplate 500 and the base. The cover 200 separates the connecting bridge 33 of each grounding element 300 from the base 10 of the grounding plate 100. More specifically, the base 10 of the grounding plate 100 is disposed on the base, and the cover 200 covers the base 10. The cover 200 serves to cover conductive components (including the grounding plate 100) located in the base.

[0039] See Figure 6 and Figure 7 The cover plate 200 has a through hole 201 in the middle, which allows the U-shaped grounding portions 34 of the two grounding members 300 to be inserted into the clamping space 13. In some embodiments, the through hole 201 is, for example, rectangular, and the length direction of the through hole 201 is consistent with the length direction of the rectangular hole 101. The first tear portion 11 and the second tear portion 12 extend into the through hole 201.

[0040] See Figure 1 and Figure 7 In some embodiments, both the first tear 11 and the second tear 12 are bent or arc-shaped. Specifically, the middle portions of the first tear 11 and the second tear 12 are close to each other to clamp the U-shaped grounding portions 34 of the two grounding members 300. The free ends of the first tear 11 and the second tear 12 extend in a direction away from each other. In this way, the shapes of the first tear 11 and the second tear 12 facilitate the insertion of the U-shaped grounding portions 34 of the two grounding members 300 into the clamping space 13, thereby facilitating the installation of the two grounding members 300 and the grounding plate 100.

[0041] See also Figure 1 and Figure 7 In some embodiments, the through hole 201 of the cover plate 200 is provided with a first covering portion 21 and a second covering portion 22 on two opposite edges (which may be referred to as the first edge and the second edge) in the length direction. The first covering portion 21 extends from the first edge of the through hole 201 toward the free end of the first tear portion 11. The free end of the first covering portion 21 covers the free end of the first tear portion 11 without affecting the insertion of the U-shaped grounding portions 34 of the two grounding members into the clamping space 13. The second covering portion 22 extends from the second edge of the through hole 201 toward the free end of the second tear portion 12. The free end of the second covering portion 22 covers the free end of the second tear portion 12 without affecting the insertion of the U-shaped grounding portions 34 of the two grounding members into the clamping space 13. This can prevent the U-shaped grounding portions 34 of the two grounding members 300 from abutting against the free ends of the first tear portion 11 and / or the free ends of the second tear portion 12 when they are inserted into the clamping space 13, thus avoiding undesirable deformation of the first tear portion 11 and the second tear portion 12.

[0042] See also Figure 1 and Figure 7 In some embodiments, the free end of the first tear 11 has a first protrusion 111, and the free end of the second tear 12 has a second protrusion 121. The free end of the first covering portion 21 has a first hook 211, which abuts against the first protrusion 111 to prevent the first tear 11 from being excessively deformed and causing its free end to enter the movement path of the U-shaped grounding portion 34 of the two grounding members 300. The free end of the second covering portion 22 has a second hook 221, which abuts against the second protrusion 121 to prevent the second tear 12 from being excessively deformed and causing its free end to enter the movement path of the U-shaped grounding portion 34 of the two grounding members 300.

[0043] In some embodiments, the base 10 may include snap-fit ​​holes 102 located on both sides of the rectangular hole 101. The snap-fit ​​holes 102 may, for example, snap-fit ​​with a support frame (not shown) mounted in the base.

[0044] See Figure 8 In some variant embodiments of the grounding piece 100, the free end of the first tear portion 11 may not have a first protrusion 111, and the free end of the second tear portion 12 may not have a second protrusion 121. Correspondingly, the free end of the first covering portion 21 may not have a first hook portion 211, and the free end of the second covering portion 22 may not have a second hook portion 221. The grounding piece 100 can achieve the inventive objective of this application simply by cutting the first tear portion 11 and the second tear portion 12 as described above onto the base 10.

[0045] The socket 1000 provided in this embodiment of the disclosure obtains a first tear 11 and a second tear 12 by cutting the middle position of the base 10 of the grounding piece 100. The first tear 11 and the second tear 12 achieve the connection between the grounding piece 100 and the two grounding members 300 by clamping the protruding portions (e.g., U-shaped grounding portions 34) of the two grounding members 300. Compared with forming a protrusion by folding the middle part of the grounding piece 100 and clamping the protrusion between the two grounding members 300 to achieve the connection between the grounding piece 100 and the two grounding members 300, the grounding piece 100 provided in this embodiment of the disclosure requires less material, which is beneficial to saving costs. Moreover, the structure of the grounding piece 100 is simple and reliable.

[0046] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
