[0031] It can be understood that, please refer to Figure 5 and Figure 6 , the insulation protection piece 50 is adapted to the shape of the third mounting groove 703, and the number of the first protection end 501 of the insulation protection piece 50 is two, and the number of the first PE end 201 of the PE terminal 20 extending from the first protection end 501 is two.

[0032] It is worth noting that in some embodiments, please refer to Figure 3 andFigure 5 The bottom of the first mounting groove 701 is provided with a first connecting hole 701h for exposing the N terminal 30, the shell 101 is provided with a first through hole 11h corresponding to the first connecting hole 701h, and the first through hole 11h and the first connecting hole 701h are used for electrically connecting the N terminal 30 with an external first pin; the bottom of the second mounting groove 702 is provided with a second connecting hole 702h for exposing the L terminal 40, the shell 101 is provided with a second through hole 12h corresponding to the second connecting hole 702h, and the second through hole 12h and the second connecting hole 702h are used for electrically connecting the L terminal 40 with an external second pin. Through the above arrangement, a mode of electrically connecting the N terminal 30 with an external first pin and electrically connecting the L terminal 40 with an external second pin is provided.

[0033] It is worth noting that, in some embodiments, referring to Figure 3 , Figure 5 and Figure 6 , the bracket 70 is provided with a sliding groove 704, the sliding groove 704 is arranged on the side of the bracket 70 away from the cover plate 102, and the socket 100 further includes a sliding block 80 and an elastic member 90 both arranged in the sliding groove 704; one end of the elastic member 90 abuts against the groove wall of the sliding groove 704, and the other end of the elastic member 90 abuts against the sliding block 80; the sliding block 80 is provided with a first sliding channel 801 facing the first through hole 11h and a second sliding channel 802 facing the second through hole 12h; when the external first pin abuts against the first sliding channel 801 and the external second pin abuts against the second sliding channel 802, the external first pin and the external second pin push the sliding block 80 to move to compress the elastic member 90, so as to expose the first connecting hole 701h and the second connecting hole 702h, so as to electrically connect the N terminal 30 with the external first pin and electrically connect the L terminal 40 with the external second pin. Through the above arrangement, another mode of electrically connecting the N terminal 30 with an external first pin and electrically connecting the L terminal 40 with an external second pin is provided.

[0034] It is worth noting that, in some embodiments, the elastic member 90 is a spring.

[0035] It is worth noting that, in some embodiments, the number of the elastic members 90 is two, one of the elastic members 90 is arranged between the first sliding channel 801 and the groove wall of the sliding groove 704, and the other of the elastic members 90 is arranged between the second sliding channel 802 and the groove wall of the sliding groove 704.
