Cable terminal and processing method thereof

Abstract

The invention discloses a cable wiring terminal and a machining method therefor. The wiring terminal comprises a wiring block, wherein the center of the wiring block is provided with a through hole, and two ends of the wiring block are respectively provided with a wire clamping groove which can enable a cable to be embedded. The minimum width L of a wire clamping inlet of each wire clamping groove is less than the maximum width D of the wire clamping groove. The wiring terminal also comprises a wire clamping piece which compresses the cable and enables the cable to be fixed in the wire clamping groove. The width M of the wire clamping piece is greater than the minimum L of the wire clamping inlet. The area of the cable formed by the enclosing of the wire clamping grooves and the wire clamping piece is less than the area of an external cable of the wiring block. The wire clamping inlet is rectangular or shaped like a loudspeaker. The wire clamping groove close to the wire clamping inlet is provided with a plane. The wire clamping inlet and the plane form an inclined angle R. The wire clamping grooves are shaped like C. The invention also discloses a machining method for the wiring terminal. The wiring terminal is simple in structure, is low in cost, is convenient to machine, is small in contact resistance, is stable in electrical performance, is free of maintenance, and saves the materials.

Description

technical field [0001] The invention relates to a cable terminal, which is mainly used in the field of electric equipment. Background technique [0002] The cable connection of power equipment is an indispensable part of the equipment. When the connection is under high current conditions, the requirements for cable connection are even higher. For example, in power equipment, power capacitors need to be connected. Power capacitors can be divided into mobile Item capacitors, series capacitors, heating capacitors, coupling capacitors, pulse capacitors, DC capacitors, circuit breaking capacitors, filter capacitors, protective capacitors and standard capacitors, etc. Parallel capacitors are used in power equipment and systems to improve the power factor; series capacitors are connected in series in transmission lines or grids to compensate for the inductance of transmission lines; different capacitor devices are selected in different places, and each capacitor device has dozens t...

Problems solved by technology

When this structure is adopted, the cable 3 is clamped and fixed by screws and nuts. Due to the non-rigid structure of the cable 3, as time goes on, under the influence of wind force, high and low temperature changes, etc., it will gradually deform and the contact resistance will decrease. It will increase, because the current is very large, it will produce a large voltage drop, and it will be burnt and blackened in severe cases. In order to solve this technical problem, electric workers need to perform regular maintenance and further tighten the screws and nuts. Because many power towers are located in the wilderness In the wild, the tower is high and the road is far away, and the maintenance cost is very high. For this reason, the Chinese patent has disclosed, CN201310419203.X, the cable lead-out electrode and the punching die and processing method of the cable lead-out electrode. Improvements have been made, but the processing is complicated, especially the processing method of turning the metal sleeve and the cable at an angle to flatten the ribs is cumbersome and inconvenient. In addition, from the cable to the lead-out electrode, and then from the lead-out electrode to the clamp, the contact resistance will increase
