Problems solved by technology

[0004] 1. The interface does not match
Due to the different specifications of the wires that need to be connected, the diameters of the wires vary, and the connection structures of various electrical equipment or electromechanical products tend to be standardized (that is, a certain type of product usually only provides one cable connection interface), it is difficult to To adapt to the connection requirements of cables of different specifications in the market and applications, in practice, it often happens that thick cables are connected to thin wiring holes or thin cables are connected to thick wiring holes—both wiring efficiency and connection quality will be affected; moreover, Due to the different diameters of the wires that need to be connected, the area or connection quality of the electrical connection established by it also shows a large difference-thin wires have a small electrical contact area, and thick wires have a large electrical connection area
[0005] 2. When the cable to be connected is a multi-strand wire, due to the action of the compression screw and/or the twisting during assembly, the multi-strand wires that are hinged together are very easy to scatter, which will cause tension between the cable and the terminal. el

Abstract

The invention discloses a wire switching apparatus. The wire switching apparatus comprises a switching apparatus body, a pressure block, and a locking apparatus for detachable connection with the switching apparatus body and the pressure block. One surface of the switching apparatus body is provided with a concave-convex pressing line structure, correspondingly, one surface of the pressure block is provided with a matched concave-convex pressing line structure, one end of the switching apparatus body or the pressure block is provided with a plugging terminal for cooperating with a plugging hole for application, and the other end of the switching apparatus body or the pressure block is provided with a limiting structure for preventing a lead wire from transversely slipping off. The wire switching apparatus can rapidly and reliably connect a wire with a power device or a dynamo-electric product, and also has the advantages of simple operation, good electrical property, high wiring efficiency and the like.

Description

technical field [0001] The invention relates to the field of power cable connection, in particular to a wire transfer device for connecting wires to electric equipment or electromechanical products. Background technique [0002] When the existing power equipment or mechanical and electrical products are connected to the power line, the electrical connection between the wire and the internal circuit is usually established by using a wiring hole and a compression screw. like Figure 11 and Figure 12 As shown, the wiring structure of electric equipment or electromechanical products generally includes casing wiring holes 111, terminal blocks 112 and compression screws 113, wherein: terminal blocks 112 are used to connect internal circuits and external cables, and compression screws 113 are used to Press the wires onto the terminals, and the casing wiring holes 111 are used to pass through and accommodate the wires; the terminals 112 are provided with threaded holes 122 for coo...
