One end of the spring piece 5 and one end of the wiring piece 211 are both movable ends, and the other end of the spring piece 5 and the other end of the wiring piece 211 are both fixed ends. The movable ends of the spring piece 5 and the wiring piece 211 are arranged side by side and are both oppositely arranged with the wiring wall body 213, and can be used to clamp the hard wire 810 and the insertion piece 83. Specifically, based on Figure 1 , and in combination with Figure 7, the wiring part 210 is provided with a connecting wall body 212 arranged vertically with the wiring piece 211, and a mounting wall body 214 arranged front and back opposite to the wiring wall body 213. The connecting wall body 212 is connected between the wiring wall body 213 and the mounting wall body 214. The wiring piece 211, the connecting wall body 212, the wiring wall body 213 and the mounting wall body 214 are integrally bent and formed. The spring piece 5 is independently arranged. The spring piece 5 and the wiring piece 211 are arranged side by side in the left - right direction. The fixed ends of the spring piece 5 and the wiring piece 211 are respectively fixed on the mounting wall body 214.

The spring piece 5 has a large elasticity, and the wiring piece 211 has a small elasticity but a large clamping force. Therefore, the spring piece 5 can be used alone to connect the hard wire 810, and the spring piece 5 and the wiring piece 211 are used together to connect the plug - in piece 83. The hard wire 810 is usually cylindrical or approximately cylindrical and can be a wire with the insulating layer stripped; the plug - in piece 83 is a sheet - like structure with a larger width but a thinner thickness. When connecting the hard wire 810, the hard wire 810 is inserted into the wiring part 210 of the socket sleeve, and the hard wire 810 is inserted between the movable end of the spring piece 5 and the wiring wall body 213 of the wiring part 210 ( Figure 5 ); when connecting the plug - in piece 83, the plug - in piece 83 is inserted into the wiring part 210, where half of the plug - in piece 83 is inserted between the wiring piece 211 and the wiring wall body 213 of the wiring part 210, and the other half of the plug - in piece 83 is inserted between the movable end of the spring piece 5 and the wiring wall body 213 of the wiring part 210 ( Figure 6 ). The wiring structure of the socket in this embodiment adopts a dual - purpose plug - in structure in which the side - by - side spring piece 5 and wiring piece 211 cooperate with the wiring wall body 213, so as to realize the ability to connect both the hard wire 810 and the plug - in piece 83, which is simple and convenient and has a firm connection.

[0046] As Figure 7 shown, both ends of the wiring piece 211 in this embodiment are connected in a V - shape. There is a first inlet 216 between the movable end of the wiring piece 211 and the wiring wall body 213. The fixed end of the wiring piece 211 is connected to the mounting wall body 214 in an integral connection manner. The movable end of the wiring piece 211 is provided with an arc part 215 at the connection with the fixed end for abutting against the wiring wall body 213. The structural design of the wiring piece 211 facilitates the connection and insertion of the plug - in piece 83.

[0047] The matching structure between the spring piece 5 and the wiring part 210 of the socket sleeve in this embodiment is as Figure 4 and Figure 10 shown. The movable end of the spring piece 5 has a cutting edge 53, and the cutting edge 53 is in abutting fit with one side wall of the triangular groove 219 on the wiring wall body 213 to form a second inlet 52.

The fixed end of the spring piece 5 has a hook 51 bent away from the movable end. The hook 51 passes through the through hole 218 and is in abutting cooperation with the clamping edge 217.

[0048] As Figure 1 , Figure 11-12 shown, the wiring structure of the socket has a multi-pole socket and a plurality of spring pieces 5 arranged in one-to-one correspondence. By rotating the wire-removing wrench 6, the plurality of spring pieces 5 are simultaneously driven away from the wiring wall 213 of the corresponding socket. One end of the wire-removing wrench 6 is provided with a handle 61, and the other end is provided with a plurality of driving parts 65 corresponding to and drivingly connected to the movable ends of the plurality of spring pieces 5. The arrangement of the wire-removing wrench 6 enables multi-pole simultaneous wire removal in one operation by pressing with the hand. Specifically, as Figure 10-12 shown, the spring piece 5 is provided with a bent portion 54 connected between the fixed end and the movable end. The wire-removing wrench 6 includes a rotating rod 62 connected to the handle 61. Both ends of the rotating rod 62 are provided with rotating shafts 63 for rotational mounting. The rotating rod 62 is located at the rear side of the fixed end of the spring piece 5.

The pressing plate 1 is provided with a first rib 13 corresponding to the wiring part 210 of the socket sleeve and a jack 11 corresponding to the socket part 220. The socket sleeve is inserted into the receiving cavity and snapped into the limiting groove 72, and also abuts against the first rib 13 of the pressing plate 1. Buckles 75 are arranged on both left and right sides in the receiving groove 71, and bayonets 14 engaged with the buckles 75 are arranged on the outer sides of the left and right sides of the pressing plate 1; and / or, ribs 76 are arranged on the front and rear sides in the receiving groove 71, and a pair of clamping feet 15 are arranged on each of the front and rear sides of the pressing plate 1. A clamping gap is formed between the pair of clamping feet 15, and the ribs 76 are engaged with the clamping gap. When the pressing plate 1 is buckled on the base 7, the buckles 75 of the base 7 are snapped into the bayonets 14 of the pressing plate 1; the ribs 76 of the base 7 are snapped into the clamping gap of the pressing plate 1. A clamping type fixing structure is adopted between the base 7 and the pressing plate 1, which is convenient for disassembly and assembly and has a firm and reliable connection.

[0052] As Figure 13-16As shown, on the left and right sides inside the receiving groove 71, there are provided shaft grooves 74 for rotatably mounting the wire-retracting wrench 6. The socket sleeve is located between the two shaft grooves 74 in the left-right direction. On the pressing plate 1, there are provided second ribbing 12 corresponding to the shaft grooves 74. On the base 7, there is provided a handle hole 77 through which the handle 61 of the wire-retracting wrench 6 can pass out.
