Figure 4 An exploded view of the grounding assembly 100 is shown. Figure 5 An exploded view of the grounding assembly 100 is shown. Figure 1 An exploded view of the grounding assembly 100 is shown. Figure 6 An exploded view of the grounding assembly 100 is shown. Figure 5 An exploded view of the grounding assembly 100 is shown.
[0025] The grounding assembly 100 is installed inside the housing 50 of the socket 500, which is for example a Schuko socket. Specifically, referring to Figure 3 , the housing 50 is provided with two outlets 51, and the bottom wall of each outlet 51 is provided with a slot 511 and a slot 512 for cooperating with two pins (not shown in the figure) of a plug, for example a Schuko plug, one of which is connected to the live wire and the other to the neutral wire.
[0026] The peripheral wall of each socket 51 is provided with two openings 513. The two grounding tabs (see below first grounding tab 11 and second grounding tab 12) of the grounding member 10 have portions (more specifically, the guide portions 123) that extend into one socket 51 through the two openings 513 of the socket 51, and the plug can achieve grounding by the abutment of the two grounding contacts with the guide portions 123. The two grounding tabs (see below first grounding tab 21 and second grounding tab 22) of the grounding member 20 have portions (more specifically, the guide portions 223) that extend into another socket 51 through the two openings 513 of the other socket 51, and the plug can achieve grounding by the abutment of the two grounding contacts with the guide portions 223.
[0027] Referring to Figure 1 and Figure 2 , the grounding member 10 can include a first grounding tab 11, a connecting bridge 13, a U-shaped grounding portion 14, and a second grounding tab 12.
[0028] The connecting bridge 13 corresponds to the bottom wall of the socket 51. The first end of the connecting bridge 13 is connected to the first grounding tab 11, and the second end of the connecting bridge 13 is connected to the second grounding tab 12 through the U-shaped grounding portion 14. The connecting bridge 13 is provided with a mounting hole 130, and a fastener (not shown) passes through the mounting hole 130 to fix the connecting bridge 13 on the housing 50.
[0029] In some embodiments, the first grounding tab 11 is connected to the first end of the connecting bridge 13 and extends to the first side of the connecting bridge 13. As mentioned above, the end of the first grounding tab 11 away from the connecting bridge 13 can be provided with a guide portion 123 that can extend into one opening 513 of the corresponding socket 51 to connect with one grounding contact of the plug.
[0030] The opening of the U-shaped grounding portion 14 faces the first side of the connecting bridge 13. The U-shaped grounding portion 14 includes opposite first and second side plates 141 and 142. The first side plate 141 extends from the second end of the connecting bridge 13 to the second side of the connecting bridge 13, and the second side plate 142 is located outside the first side plate 141. The second side plate 142 is provided with two clamping grooves 140 on the edges of the opposite sides of the second side plate 142, and the two clamping grooves 140 can be, for example, open grooves.
[0031] The second grounding tab 12 extends from the second side plate 142 to the first side of the connecting bridge 13. The second grounding tab 12 is opposite to the first grounding tab 11. As mentioned above, the end of the second grounding tab 12 away from the connecting bridge 13 can be provided with a guide portion 123 that can extend into the other opening 513 of the corresponding socket 51 to connect with the other grounding contact of the plug.
[0032] The first grounding spring 11 and the second grounding spring 12 are inclined towards each other to allow the respective guiding portions 123 to protrude into the socket 51 through the corresponding openings 513. When the plug is inserted into the socket 51, the first grounding spring 11 and the second grounding spring 12 are elastically deformed, so that the two guiding portions 123 reliably abut against the two grounding contacts on the plug.
[0033] In some embodiments, each guiding portion 123 is designed in a shape that facilitates the insertion and extraction of the plug into and from the socket 51.
[0034] In some embodiments, at least one side edge of the first grounding spring 11 is provided with a first stop portion 111 protruding outward, and at least one side edge of the second grounding spring 12 is provided with a second stop portion 121 protruding outward. The first stop portion 111 and the second stop portion 121 can abut against the peripheral wall of the socket 51 at the corresponding openings 513, so as to avoid the respective guiding portions 123 from protruding excessively into the socket 51 and affecting the normal insertion of the plug.
[0035] The grounding member 20 comprises a first grounding spring 21, a connecting bridge 23, a U-shaped grounding portion 24 and a second grounding spring 22. The first end of the connecting bridge 23 is connected with the first grounding spring 21, and the second end of the connecting bridge 23 is connected with the second grounding spring 22 through the U-shaped grounding portion 24. The U-shaped grounding portion 24 comprises opposite first and second side plates 241 and 242. The structures of the first grounding spring 21, the connecting bridge 23, the U-shaped grounding portion 24 and the second grounding spring 22 and the connection relationship therebetween can be the same as those of the first grounding spring 11, the connecting bridge 13, the U-shaped grounding portion 14 and the second grounding spring 12, and will not be described herein again.
[0036] It can be understood that the connecting bridge 23 is provided with a mounting hole 230, which has the same function as the mounting hole 130. At least one side edge of the first grounding spring 21 is provided with a first stop portion 211 protruding outward, and at least one side edge of the second grounding spring 22 is provided with a second stop portion 221 protruding outward. The first stop portion 211 and the second stop portion 221 have the same function as the first stop portion 111 and the second stop portion 121. In addition, the distal ends of the first grounding spring 21 and the second grounding spring 22 can be respectively provided with guiding portions 223, which have the same function as the guiding portions 123.
[0037] Referring to Figure 1 and Figure 2The structure of the second side plate 242 of the U-shaped grounding part 24 is different from that of the second side plate 142 of the U-shaped grounding part 14. Specifically, no clamping groove 140 is arranged on the second side plate 242, but two connecting lugs 240 are arranged on the edges of the opposite sides of the second side plate 242. An outwardly extending clamping protrusion 2401 is arranged on each end of each connecting lug 240.
[0038] In manufacturing the grounding part 10, the metal plate can be first punched into a sheet-shaped metal part, and then the sheet-shaped metal part is subjected to bending processing to form the shape of the grounding part 10 shown in FIG. 1. Figure 2 In manufacturing the grounding part 20, the metal plate can be first punched into a sheet-shaped metal part, and then the sheet-shaped metal part is subjected to bending processing to form a shape close to the grounding part 20 shown in FIG. 2. Before the grounding part 20 is connected with the grounding part 10, each connecting lug 240 can be, for example, in the same plane as the second side plate 242, or each connecting lug 240 can be inclined relative to the second side plate 242. Figure 2
[0039] In assembling the grounding part 10 and the grounding part 20 into the grounding part assembly 100, the second side plate 142 of the grounding part 10 and the second side plate 242 of the grounding part 20 are first abutted with each other, and then each connecting lug 240 is bent to enable the clamping and fitting of each connecting lug 240 and the corresponding clamping groove 140 (see FIG. 3), so that the grounding part 10 and the grounding part 20 are reliably fixed together. Figure 1
[0040] Referring to FIG. 4, the housing 50 can be provided with a grounding sheet 300 including two oppositely arranged grounding springs 31. The U-shaped grounding part 14 and the U-shaped grounding part 24 of the grounding part assembly 100 can be clamped between the two grounding springs 31. The grounding sheet 300 can be connected with the grounding terminal of the socket 500. Figure 4
[0041] In the grounding part assembly 100 of the embodiment of the present disclosure, the grounding part 10 and the grounding part 20 are fixed together by clamping after being shaped respectively, and compared with the scheme of integrally forming the two grounding parts, the design of the mold is simplified, the size of each grounding part is easy to control, the waste generated in the processing process is less, and the cost is also reduced. Moreover, the grounding part 10 and the grounding part 20 are fixed together by clamping, the fixing mode is simple, and the connection of the two is very firm.
[0042] It should be noted that the embodiments of the grounding part 10 and the grounding part 20 are not limited to the above examples, and for example, there can be but are not limited to the following variants:
[0043] In some embodiments, the number of the clamping slots 140 on each second side plate 142 is not limited to two. Correspondingly, the number of the connecting ears 240 on each second side plate 242 is not limited to two.
[0044] In some embodiments, the two side edges of each second side plate 142 can be provided with not only the clamping slots 140 but also the connecting ears. Correspondingly, the two side edges of each second side plate 242 are provided with both the clamping slots and the connecting ears 240. When the second side plate 142 and the second side plate 242 abut, the connecting ears 240 of the second side plate 242 can be folded to be clamped with the clamping slots 140 of the second side plate 142, and the connecting ears of the second side plate 142 can be folded to be clamped with the clamping slots of the second side plate 242.
[0045] In some embodiments, for example, referring to Figure 5 and Figure 6 , each connecting ear 240 is not provided with a clamping protrusion 2401, and each connecting ear 240 can be folded to form a U-shaped slot 2402 with the second side plate 242 while being clamped with the corresponding clamping slot 140, so that the second side plate 241 is clamped in the U-shaped slot 2402. In this way, the grounding member 10 and the grounding member 20 are equivalent to being riveted together, and the reliable fixation of the grounding member 10 and the grounding member 20 can be achieved.
[0046] In some embodiments, the setting position of each clamping slot is not limited to the edges of the opposite sides of the second side plate where it is located, and it can be a closed slot on the second side plate, for example. Correspondingly, the setting position of each connecting ear is not limited to the edges of the opposite sides of the second side plate where it is located, and it can be as long as it can pass through the corresponding clamping slot to reliably fix the grounding member 10 and the grounding member 20 together. The number of clamping slots can be one or more, and the number of connecting ears can also be one or more.
[0047] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical applications, or technical improvements in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
