In the related art, as shown in fig. 1, a circuit breaker 100 has a structure in which a wire inlet 101 is provided at one end of the circuit breaker 100, and a terminal bolt 102 is further provided at the wire inlet 101. When the electric wire is inserted into the wire inlet 101, the fixed connection of the electric wire to the circuit breaker 100 is achieved by tightening the terminal bolt 102. The specific structure of the wire inlet 101 is the prior art and will not be described herein.
The present embodiment provides a wiring structure for a circuit breaker for connecting an electric wire and a wire inlet 101 in a circuit breaker 100. As shown in fig. 1 to 4, the wiring structure for a circuit breaker includes an insulated wire case 1, a wire connecting mechanism 3, and a platen mechanism 4. Insulating wire casing 1 is including insulating grafting end, and insulating grafting end can insert into inlet 101 in, the inside installation cavity that is provided with of insulating wire casing 1, and the installation cavity is served at insulating grafting and is formed electrically conductive mouth 122. The electric wire connection mechanism 3 includes a conductive member 31 disposed below the conductive opening 122, the conductive member 31 being configured to be electrically connected to an electric wire. The pressing plate mechanism 4 includes a conductive pressing plate 41 and an elastic member 43, the conductive pressing plate 41 is disposed at the conductive port 122 and spaced from the conductive member 31, the elastic member 43 is sandwiched between the conductive member 31 and the conductive pressing plate 41, and at least one of the conductive member 31 and the conductive pressing plate 41 and the elastic member 43 are disposed in an insulating manner. When pressed, the conductive platen 41 can move to a first position to contact the conductive member 31 to conduct the wire and the circuit breaker 100. After the conductive pressing plate 41 is pressed, the conductive pressing plate 41 can move to the second position, and is separated from the conductive member 31, so that the electric connection between the electric wire and the circuit breaker 100 is broken.
With the above arrangement, the terminal bolt 102 is aligned with the conductive pressing plate 41 in the pressing plate mechanism 4 by electrically connecting the electric wire to the conductive member 31, inserting the insulating insertion terminal of the insulated wire case 1 into the wire inlet 101, and aligning the conductive port 122 with the terminal bolt 102. When the circuit breaker 100 has no fault (in daily use), the wiring bolt 102 is tightened to apply pressure to the conductive pressing plate 41, and the conductive pressing plate 41 is driven to move below the conductive port 122, so that the conductive pressing plate 41 is in contact with the conductive piece 31, thereby realizing the electrical connection between the wire inlet 101 and the electric wire and ensuring the normal use of the circuit breaker 100.
When the circuit breaker 100 is out of order and needs to be replaced, the wiring bolt 102 is unscrewed, the pressed state of the conductive pressing plate 41 can be finished, the conductive pressing plate 41 is lifted away from the conductive piece 31 under the action of the elastic piece 43, and the electric connection between the wire inlet 101 and the electric wire is disconnected. It should be noted that although the elastic member 43 is interposed between the conductive member 31 and the conductive pressing plate 41, since at least one of the conductive member 31 and the conductive pressing plate 41 is disposed to be insulated from the elastic member 43, the presence of the elastic member 43 does not cause the electrical continuity between the conductive pressing plate 41 and the conductive member 31 after the conductive pressing plate 41 is lifted off the conductive member 31. At this time, the breaker 100 can be replaced by pulling out the insulated wire case 1 from the inlet 101. After the insulated wire casing 1 is taken out, only the conductive pressing plate 41 is exposed from the conductive port 122, and the conductive pressing plate 41 is not electrified, so that insulation between workers and wires can be realized, and absolute safety of the workers is guaranteed.

Alternatively, the wrapping sheath 12 may be made of rubber or the like, and has both good insulation and good wrapping property. Further, the opening-preventing portion 13 is further disposed at the conductive opening 122, so that the opening of the conductive opening 122 is prevented from being excessively expanded or even torn in a long-term use process, and the reliability of the structure is guaranteed.
Optionally, as shown in fig. 2, a wire fixing member 2 is further disposed inside the insulated wire shell 1, and the wire fixing member 2 includes a middle shaft post 21 and a clamping ring 22 disposed outside the middle shaft post 21 with a spacer. The electric wire is wound on the middle shaft post 21 and is electrically connected with the conductive piece 31 through the middle shaft post 21, and the clamping ring 22 is used for clamping the electric wire wound on the middle shaft post 21, so that the electric wire is convenient to install in the insulated electric wire shell 1, and the electric wire is well fixed in the insulated electric wire shell 1. Specifically, the wire fixing member 2 is mounted in the heat shrinkable tube 11.
Further, as shown in fig. 6, in order to enhance the stability of the connection between the wire fixing member 2 and the electric wire and prevent the electric wire from falling off the wire fixing member 2, the structure of the center post 21 and the clamp ring 22 is variously set in this embodiment. Specifically, the radial dimension of the end of the center post 21 connected to the conductive member 21 is smaller than the radial dimension of the other end of the center post 21. Along the axial direction, a plurality of annular convex parts 211 are arranged on the middle shaft post 21 at intervals. And from the second end to the first end of the insulated wire case 1, the radial dimension of the annular convex portion 211 is gradually reduced to be arranged in a cone shape. The clamping ring 22 comprises two snap ring structures 221 arranged staggered relatively on both sides of the bottom bracket post 21. Each snap ring structure 221 is in a fence shape and includes a plurality of snap ring units arranged at intervals. When the two snap ring structures 221 are closed, the electric wire wound on the central shaft column 21 can be clamped. Specifically, the clamp ring 22 may be made of a thin iron sheet and have good moldability.
In this embodiment, in order to facilitate the connection between the central post 21 and the conductive member 31, an adaptor member 23 is further provided in the wire fixing member 2 as shown in fig. 2. The adaptor 23 is lapped on the conductive piece 31, so that the installation is convenient, the axial installation space of the insulated wire shell 1 is saved, and the whole structure is more compact. Optionally, the adaptor 23 is welded to the conductive member 31, and the structure is stable. Further, the center pillar 21 can be integrated with the adaptor 23, and the center pillar and the adaptor do not need to be installed before use. Of course, as shown in fig. 6, a fixing bottom plate 24 connected to the adaptor 23 may also be disposed in the wire fixing member 2, so that the clamping ring 22 is connected to the adaptor 23 through the fixing bottom plate 24, thereby achieving an integrated arrangement of the whole structure of the wire fixing member 2, and facilitating use.

When the conductive pressing plate 41 slides along the on-off column through the conductive hole 411, the conductive pressing plate 41 can reach the first position to contact with the conductive block 312, so as to be electrically connected with the conductive member 31; the conductive pressure plate 41 can also reach a second position in contact with the insulating block 32, thus being insulated from the conductive member 31.
