[0045] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific implementation manners. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, elements and circuits well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0046] As Figures 1 to 11 shown, a rapid wiring structure for a contactor includes: a coil bobbin 3, a wiring leaf spring 2 and a push rod 1. The coil bobbin 3 is installed in the accommodation cavity formed by a base 5 and a base 4. A plurality of mounting grooves are provided on the coil bobbin 3.

[0047] The installation groove includes: a first accommodation cavity 31 and a second accommodation cavity 32. The first accommodation cavity 31 and the second accommodation cavity 32 are arranged side by side in the installation groove. The push rod 1 is installed in the first accommodation cavity 31, and the wiring piece spring 2 is installed in the second accommodation cavity 32;

[0048] The push rod 1 and the wiring piece spring 2 are slidably connected to each other.

[0049] In the above manner, it can be seen that in the present utility model, the push rod 1 is used to open the first extension portion 212 and the second extension portion 222 of the wiring piece spring 2, thereby facilitating the wiring installation of external wires. This structure utilizes the elastic force of the wiring piece spring 2 to clamp and fix the wires. The first clip and the second clip are in a V-shaped structure. When the wire is subjected to an outward pulling force, the first distal end 211 and the second distal end 221 will be in a barb shape and embed into the surface of the conductor, which can prevent the wire from being pulled out due to external force. The above structure is arranged in pairs on the contactor to connect the incoming wire and the outgoing wire of the control coil.

[0050] Specifically, in this embodiment, the wiring piece spring 2 includes a connecting portion 23, a clamping portion, and an installation portion 25. The installation portion 25 is connected to the connecting portion 23 by integral molding or welding. The clamping portion is connected to the installation portion 25 by integral molding or welding to ensure that the connecting portion, the clamping portion, and the installation portion can be tightly connected and fixed to each other, avoiding displacement or fracture due to external force. In this embodiment, the wiring piece spring 2 is made of an elastic metal material and is integrally formed by stamping.

[0051] In addition, it should be noted that the connecting portion 23 includes a first connecting portion and a second connecting portion. One end of the first connecting portion is connected to one end of the second connecting portion by integral molding. The first connecting portion is perpendicularly connected to the second connecting portion. The connecting portion 23 is used to connect to one end of the enameled wire of the contactor coil.

[0052] Further, it should be noted that the clamping portion includes a first clamping piece 21 and a second clamping piece 22. The first clamping piece 21 and the second clamping piece 22 have the same structure and equal size. One end of each of the first clamping piece 21 and the second clamping piece 22 is connected to the mounting portion 25. In this embodiment, the first clamping piece 21 and the second clamping piece 22 are connected by integral molding or welding. A wire clamping opening 24 is formed by a first distal end 211 of the first clamping piece 21 and a second distal end 221 of the second clamping piece 22. The wire clamping opening 24 is presented as a closed opening or a narrow slit. The distance between the first clamping piece 21 and the second clamping piece 22 near the mounting portion 25 is greater than the distance away from the mounting portion 25, so that the first clamping piece 21 and the second clamping piece 22 are in a V-shaped state. When the push rod 1 is movable in the x direction within the range of the x1 position and the x2 position, when the push rod 1 moves in the x direction from the x1 position to the x2 position, the wedge block 11 pushes the first clamping piece 21 and the second clamping piece 22 to open, and the wire clamping opening 24 expands. When the push rod 1 moves from the x2 position to the x1 position, the wire clamping opening 24 shrinks due to the elasticity of the leaf spring of the first clamping piece 21 and the second clamping piece 22.

[0053] In addition, it should be noted that it further includes a first extension portion 212 and a second extension portion 222. One side of the lower end of the first extension portion 212 is connected to the upper end of the first clamping piece 21. One side of the lower end of the second extension portion 222 is connected to the upper end of the second clamping piece 22. The first extension portion 212 and the second extension portion 222 are in an arc-shaped bending state. The bent portions of the first extension portion 212 and the second extension portion 222 are close to each other. The wedge block 11 is below the push rod 1. When the push rod 1 moves in the x direction from the x1 position to the x2 position, the wedge block 11 passes through the middle of the first extension portion 212 and the second extension portion 222, and the first extension portion 212 and the second extension portion 222 are pushed by the wedge block 11 to move in the reverse direction, driving the first clamping piece 21 and the second clamping piece 22 to move in the reverse direction;

[0054] The mounting portion is a frame body having a first opening 251 and a second opening 252 at both ends in the X direction. The wiring opening 321, the first opening 251, the second opening 252, and the wire clamping opening 24 are arranged in a straight line in the x direction in sequence.

[0055] In addition, it should be noted that it further includes a flanging 26. One end of the flanging 26 is connected to the lower end of the first opening 251. By providing the flanging 26 to cooperate with the notch 33, the wiring leaf spring 2 is fixed firmly in the x direction.

[0056] Further, the push rod 1 includes a push rod body, and a wedge block 11 is further provided below the push rod body. The wedge block 11 passes through between the first extension portion 212 and the second extension portion 22 in the X direction, and is used to push the first extension portion 212 and the second extension portion 222 to both sides, and drive the first clamping piece 21 and the second clamping piece 22 to open to both sides, so as to expand the wire clamping opening 24;

[0057] First convex blocks 12 and second convex blocks 13 are further provided on both sides of the push rod body, and a first convex platform 14 is further provided at the front end of the push rod body. The first convex block 12 cooperates with the sliding groove 311, and the second convex block 13 cooperates with the sliding groove 51 provided on the base 5, and jointly act to limit the sliding of the push rod 1 within the range between the x1 position and the x2 position in the x direction.

[0058] Further, a sliding groove 311 is provided in the first accommodation cavity 31. The sliding groove 311 is installed in cooperation with the first convex block 12. An entrance is provided at the edge of the first accommodation cavity 31 close to the coil bobbin. A second convex platform 312 is provided at one end of the first accommodation cavity 31 far from the entrance. An elastic member 6 is provided between the first convex platform 14 and the second convex platform 312. In this embodiment, the elastic member 6 is a spring;

[0059] The user inserts the wire into the wiring port 321 of the coil bobbin 3, passes through the first opening 251, the second opening 252 on the frame body 25 of the wiring piece spring 2, and the wire clamping opening 24 formed by the first distal end 211 and the second distal end 221. Finally, the user removes the force applied to the push rod 1. At this time, the push rod 1 moves from the x2 position to the x1 position under the spring force of the spring 6, driving the wedge block 11 to withdraw from between the first extension portion 212 and the second extension portion 222. The first clamping piece 21 and the second clamping piece 22 return to the initial state due to the elastic action of the leaf spring material, and the wire is clamped by the first distal end 211 and the second distal end 221 at the wire clamping opening 24, completing the wiring installation of the external wire. This structure uses the elastic force of the wiring piece spring 2 to clamp and fix the wire. The first clamping piece 21 and the second clamping piece 22 are in an eight-shaped structure. When the wire is subjected to an outward pulling force, the first distal end 211 and the second distal end 221 will be hooked into the surface of the conductor, which can prevent the wire from coming out due to external force.

[0060] A notch 322 is provided in the second accommodation cavity 32. A wiring port 321 is further provided at the edge of the second accommodation cavity 32. A notch 33 is provided at one end of the second accommodation cavity 32 close to the wiring port 321. The flanging 26 is snapped into the notch 33 to fix the wiring piece spring 2 firmly in the x direction. The notch 322 and the second convex block 53 of the base 5 cooperate to form a cavity for accommodating the excess wire. A first convex block 52 is provided on the base 5 to press the wiring piece spring 2 in the second accommodation cavity 32 of the coil bobbin 3.

[0061] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
