An electric protector with excellent shock resistance

Abstract

The invention discloses an electric protector with excellent shock resistance, which includes a clamping mechanism and a connecting mechanism. The invention provides a clamping mechanism inside the slot, inserts the connector into the slot and fixes it with the terminal , during the downward movement of the connector, it will press the pressure rod to move to the lower end, so that the pressure rod will pull the L-shaped plate to move to the middle of the slot through the swing rod, so that the clamp block can clamp and fix the connector, achieving the ability to The advantages of auxiliary fixing of the connector; by setting the clamping mechanism at the upper end of the connecting mechanism, after the wire is plugged into the inside of the first pressure plate and the second pressure plate, the elastic potential energy of the recovery deformation of the second return spring drives the first pressure plate and the second pressure plate. The first metal sheet and the second metal sheet on the inner side of the second pressure plate firmly clamp the wire, which changes the original method of fixing the wire by bolts, making the fixing convenient and fast.

Description

technical field [0001] The invention relates to the related field of electric protectors, in particular to an electric protector with excellent shock resistance. Background technique [0002] The function of the electric protector is to provide comprehensive protection and control to the motor. In the event of overcurrent, undercurrent, phase failure, stalled rotor, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, grounding, bearing wear, etc. When the stator and rotor are eccentric and the winding is aging, an alarm or protection control is given. [0003] When the current electric protector is used, it is often necessary to connect the connecting wire and the wire, but when the connecting wire and the wire are connected, when the electric protector is subjected to an impact force, the connecting wire will loosen and fall, and when the wire is fixed, It is often necessary to use bolts to fix them, which is time-consuming and labor-inte...

AI Technical Summary

Problems solved by technology

[0003] When the current electric protector is in use, it is often necessary to connect the connecting wire and the wire, but when the connecting wire and the wire are connected, when the electric protector is subjected to an impact force, the connecting wire will loosen and fall, and when the wire is fixed, It is often necessary to use bolts to fix them, which is time-consuming and labor-intensive. The existing electric protectors with excellent shock resistance are not easy to assist in fixing the connectors of the connecting wires, and it is not easy to quickly fix the wires, resulting in loosening of the connectors and time-consuming and labor-intensive fixing of the wires.
