Description

Improved structure of wiring terminal Technical Field The utility model relates to the technical field of electronic components, in particular to an improved structure of a wiring terminal. Background At present, the existing wiring terminal generally adopts a screw compression mode, when the traditional wiring part is used, the fastening screw needs to be unscrewed firstly, so that a gap is formed between the traditional wiring terminal and the wiring part, and then the wiring harness is inserted into the wiring terminal and the screw is screwed, so that the wiring harness is clamped and prevented from falling off. But this process has a number of drawbacks. When the pencil is single thicker copper line, copper line texture is softer, and fastening screw is easy to make copper line extrusion impaired at the screw up in-process. The damage is shown by mechanical damage to the copper wire, and the copper wire becomes easy to break, or obvious screw indentation appears at the fastened part, the cross section is changed from a cylinder to a square, and the cross section area is obviously changed. If the wire harness is made of a plurality of strands of copper wires, the fastening screw can press the copper wires loose when being tightly pressed. Moreover, in order to fasten the wire harness better, workers often install the wire harness in the wiring portion after bending the wire harness, which is not only troublesome to operate, but also introduces uncontrollable factors. For this purpose, an improved structure of the connection terminal is proposed. Disclosure of utility model The utility model aims to provide an improved structure of a wiring terminal, which adopts different structural designs for a fastening part, and adopts different connection modes with a base to realize the disassembly and assembly of clamping or loosening of an electric wire, so that the problem that a wire harness is easy to damage in the fastening process can be effectively avoided, the electric wire is not extruded, deformed or mechanically damaged in the clamping process, and the integrity and the reliability of the electric wire are ensured. In order to achieve the above purpose, the present utility model provides the following technical solutions: The improved structure of the wiring terminal comprises a fastening part, wherein the upper end of the fastening part is in threaded connection with a nut, a compression block is arranged below the nut, a base is arranged below the compression block, the fastening part penetrates through the compression block from the compression block to be connected with the base, and a spring is arranged at the part of the fastening part penetrating through the compression block to be connected with the base; preferably, the fastening component is a single-head screw rod, the bottom end of the single-head screw rod is fixedly connected with the upper end of the base, a spring is arranged at the part, which penetrates through the compression block and is connected with the base, of the fastening component, threading grooves are formed in two sides of the compression block, and threading holes are formed in the lower part of the base; Preferably, the two sides of the bottom edge of the base are provided with extension parts, the extension parts are provided with arc grooves, the arc grooves are matched with the wire penetrating grooves on the two sides of the compression block, and the arc grooves are overlapped with the central lines of the wire penetrating grooves on the two sides of the compression block; preferably, the compressing block moves in the middle part of the fastening part, one end of the spring is contacted with the compressing block, and the other end of the spring is contacted with the base; Preferably, a gasket is arranged between the nut and the compaction block; preferably, the compaction block is inverted U-shaped. Compared with the prior art, the invention has the beneficial effects that: 1. the problem that the wire is easy to cause wire harness damage in the fastening process is effectively avoided, the wire is ensured not to be extruded, deformed or mechanically damaged in the clamping process, and the integrity and the reliability of the wire are ensured. 2. Compared with the traditional wiring mode, the problem of virtual connection of the lead is effectively avoided, the stability and the reliability of electric connection are ensured, good electric performance can be maintained even in a vibrating or moving environment, and potential safety hazards caused by virtual connection are avoided.
