Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet speed regulating integrated machines, in particular to a wiring assembly for a mine-used explosion-proof and intrinsically safe permanent magnet speed regulating integrated machine. Background Art

[0002] Permanent magnet variable frequency speed regulating integrated machine is widely used in mining. Its equipment structure is relatively complex, usually including an external shell, a variable frequency speed regulating machine body installed in the external shell, and a series of wire groups, connector sockets and wall terminals for wiring installed on the external shell. These parts are adaptively designed and installed on the permanent magnet variable frequency speed regulating integrated machine according to actual needs, connected with corresponding electrical components, or power supply, or signal transmission. However, in the current permanent magnet variable frequency speed regulating integrated machine, its socket is mainly a seat hole into which one or more wires can be inserted, through which various wiring can be inserted, so that it is convenient to connect with other circuits, and the connection and disconnection between the line and the copper parts can be achieved to finally achieve the connection and disconnection of this part of the circuit. The structure is relatively conventional. However, when the traditional permanent magnet speed regulating integrated machine is in use, the socket interface and the power supply of the variable frequency regulating integrated machine may fall off when the power is on for a long time, affecting the use efficiency, and the connector socket connection is easily affected by dust in the air during use, which will affect the service life of the connector socket.

[0003] Secondly, the power cord on the existing frequency conversion and speed regulation integrated machine lacks protection during use. The line group is easily affected by the frequency conversion and speed regulation integrated machine during use, causing the line group to swing. The wire cores inside the line group affect each other, which can easily cause poor contact or short circuit, thereby affecting work efficiency.

[0004] Finally, the existing through-the-wall terminal blocks can be installed side by side on panels with thicknesses ranging from 1mm to 10mm, and can automatically compensate for the distance of the panel thickness to form terminal blocks with any number of poles, and can use isolation plates to increase air gaps and creepage distances. However, this type of traditional through-the-wall terminal is not easy to install, has poor explosion-proof performance, and is not convenient for the installation of communication media. The wiring is messy despite the simple structure, and the communication media cannot be neatly arranged quickly and conveniently, so it is less practical in actual use. Summary of the invention

[0005] The object of the present invention is to provide a wiring assembly for a mine-use explosion-proof and intrinsically safe permanent magnet speed regulation integrated machine, so as to solve the problem that during the use of the traditional permanent magnet speed regulation integrated machine proposed in the above background technology, the connector socket interface is easy to fall off and affect the use efficiency, and is easily affected by dust in the air and shortens the service life of the connector socket.

This embodiment also improves the stability of the cable during installation through the combination of epoxy resin, explosion-proof copper sleeve c5 and pressure head c11, improves the explosion-proof performance of the terminal, and facilitates the installation of the terminal in actual use.

[0053] In summary, the core working principle is roughly as follows: the through-wall terminal is provided with a sealing plate c6 inside the stud c3. When in use, the communication medium c7 is passed through the through hole c14 on the sealing plate c6, and the bare copper part c8 on the communication medium c7 is set on the sealing plate c6. The first filling layer c9 and the second filling layer c10 are provided inside the stud c3 to protect the communication medium c7, and a pressure head c11 is provided at the bottom end of the stud c3. Each communication medium c7 passes through the pressure head c11, which can press the second filling layer c10. The explosion-proof copper sleeve c5 inside the stud c3 can further improve the explosion-proof performance of the terminal, which is more practical in actual use.
