Safe coupling joint for motor test system

Abstract

The invention provides a safe coupling joint for a motor test system. The joint comprises a shell. The shell is provided with a threading hole. An upper portion in the shell is provided with a cam. The cam can rotate about a rotation shaft which penetrates an inner cavity of the shell. A surface of a cam profile is provided with an upper moving plate in a tightly contact mode. A middle portion in the shell is provided with a lower moving plate. A support spring is arranged between the lower moving plate and a bottom wall of the shell. The lower moving plate is provided with several binding post hoop components in parallel. Each binding post hoop component includes a power line terminal, a sliding rod and a fastening hoop which are successively connected from top to bottom. A lower half portion in the shell is provided with several cylindrical channels. The binding post hoop components can move in the cylindrical channels. The joint possesses advantages that dismounting is convenient; safety is good; reliability is high; production efficiency is high too and so on.

Description

technical field [0001] The invention belongs to the technical field of motor testing systems, and in particular relates to a safety coupling used in a motor testing system. Background technique [0002] For a long time, the joints of the motor test bench to connect the motor terminals have been using the traditional fish-nose pliers method, that is, fish-nose pliers are used as connectors at the end of the power test line, and clamped on the test terminals of the motor. This kind of connection is extremely unscientific And the safety is poor, the specific performance is: first, in this connection, the motor tester must first pull the wire from the test bench to the motor terminal according to the rules and procedures, connect the connector, and then return to the test bench to turn on the power switch and start testing the motor. It is not simple enough and the production efficiency is low; secondly, due to the cumbersome work process, the testers often connect the wrong mot...

[0002] For a long time, the joints of the motor test bench to connect the motor terminals have been using the traditional fish-nose pliers method, that is, fish-nose pliers are used as connectors at the end of the power test line, and clamped on the test terminals of the motor. This kind of connection is extremely unscientific And the safety is poor, the specific performance is: first, in this connection, the motor tester must first pull the wire from the test bench to the motor terminal according to the rules and procedures, connect the connector, and then return to the test bench to turn on the power switch and start testing the motor. It is not simple enough and the production efficiency is low; secondly, due to the cumbersome work process, the testers often connect the wrong motor connectors, so that the motor is burned out; thirdly, due to the high work intensity, the testers sometimes clamp the terminals with electricity It is very easy for testers to be shocked by electric shocks, resulting in casualties of staff and bringing huge negative impact on people's safety and enterprise production.
