the operating element 13 has a rotating hole 1310, a stopping end 131 and a pressing end 132, which are matched with the pin 111 to penetrate through to realize the reciprocating rotation of the operating element, the operating element 13 is rotatably arranged on the insulating shell 11 through the rotating matching of the rotating hole and the pin, the stopping end 131 has a stopping portion 1311, the pressing end 132 is located in the assembling space C, and thus, the stopping portion 1311 is rotatably arranged on the insulating shell 11;
the electrical conductor 14 is disposed in the assembly space C, the electrical conductor 14 has an electrical conductor body 141 and an electrical contact portion 142, the electrical contact portion 142 is formed above the electrical conductor body 141; for example, the electrical contact portion 142 is disposed closely to the top of the inner side of the insulating housing 11;
the elastic clamping piece 15 is arranged in the assembling space C, the elastic clamping piece 15 is provided with an elastic free part 151, a connecting part 152 and a fixing part 153 which are connected together, the connecting part 152 is connected with the fixing part 153, the fixing part 153 is fixed on the electric conductor 14, and the elastic free part 151 is positioned at the lower end of the electric contact part 142; the elastic free portion 151 of the elastic clamping member 15 is preferably disposed directly opposite the wire connection hole 110; the elastic free portion 151 is pressed by the pressing end 132 of the operating element 13 to form a clamping gap (not shown) with the electrical conductor 14, and the clamping gap corresponds to the wiring hole 110 of the insulating housing 11; wherein, the elastic clamping piece 15 is provided with a retaining matching part 15a which can be matched with the retaining part 1311 to realize the mutual clamping state and release the mutual clamping state, the retaining matching part 15a adopts a resettable structure, and the retaining matching part 15a is arranged close to the inner wall of the insulating shell 11. Specifically, the backstop mating portion 15a is located between the electrical contact portion 142 and the inner wall of the insulating housing 11. Specifically, the retaining engagement portion 15a is formed by an elastic structure, for example, the retaining engagement portion 15a is formed by extending the fixing portion 153 of the elastic clamping member 15 and bending toward the top of the insulating housing. Specifically, the retaining engagement portion 15a is formed by extending the fixing portion 153 of the elastic clamp 15 in the bottom wall direction of the insulating housing and then bending the fixing portion toward the top of the insulating housing.
In order to prevent the retaining engagement portion of the elastic clamping member from being deflected and deformed too much by the pressing force of the outside (e.g., the end of the wire inserted into the insulating housing), in this embodiment, a stopper portion 11a is provided on the inner wall of the insulating housing 11 to abut against the retaining engagement portion 15a. By providing the stopper portion 11a, the displacement distance of the portion located above the contact point between the stopper portion 11a and the backstop engagement portion 15a, which is located above the backstop engagement portion 15a, after being pushed by the lead, can be limited.
