PLC conversion terminal block structure

Abstract

The invention belongs to the technical field of terminal blocks, and discloses a PLC conversion terminal block structure which comprises a circuit board, a wiring terminal strip is fixedly installed at the top of the circuit board, a plurality of wiring ports are formed in the front face of the wiring terminal strip, and a plurality of fixing blocks located on the front faces of the wiring ports are fixedly installed on the front face of the wiring terminal strip. The front surface of the wiring terminal strip is fixedly connected with a round rod, and the outer surface of the round rod is movably sleeved with a first movable block. Through arrangement of the fixed block, the round rod, the first movable block and the threaded rod, the threaded rod can rotate along the left side of the wiring terminal strip through cooperation between the threaded rod and the wiring terminal strip, so that the first movable block can be driven to move left and right along the outer surface of the round rod through cooperation between the threaded rod and the first movable block; and meanwhile, an annular block can be formed through the first movable block and the fixed block, so that the wire can be clamped through the first movable block and the fixed block.

Description

technical field [0001] The invention belongs to the technical field of terminal blocks, in particular to a PLC transfer terminal block structure. Background technique [0002] Terminal block refers to a solid device composed of an insulating base and one or more live parts. Each conductive part can be used as a junction for the connection of two or more conductors, and also as a connection point for connecting or not connecting conductors individually. Tools; at present, when connecting the lines of the PLC control system, the staff often needs to use the terminal block structure, and the terminal block structure in the prior art can realize the basic function of connecting wires in the actual use process, but Because the wire is usually fixed by removing the insulation at the top of the wire and then clamping the copper wire inside the wire by the gasket, and the copper wire itself is relatively slender, so that the contact between the gasket and the copper wire is The are...

[0002] A terminal block refers to a solid device composed of an insulating base and more than one live part. Each conductive part can be used as a junction point for the connection of two or more conductors, and also as a connection point for individually connected or unconnected conductors. tools; at present, staff often need to use the terminal block structure when connecting the PLC control system lines, and the terminal block structure in the prior art can realize the basic function of connecting wires in the actual use process, but Because it usually fixes the wire by removing the insulation at the top of the wire and then clamping the inner copper wire through the gasket, and the copper wire itself is relatively slender, making the contact between the gasket and the copper wire The area is small, so it is easy to separate from the terminal block when the wire is pulled by external force, which affects its normal use and brings inconvenience to the staff, so it needs to be improved
