Description

Technical Field

[0001] The utility model belongs to the field of electric actuator testing, and particularly relates to a wire-splitting power-on mechanism for electric actuator testing. Background Art

[0002] A valve electric actuator refers to a precision electrical component that uses electric energy as the main energy source to drive the opening and closing of a valve. After the mechanical structure part of the valve electric actuator is completed, its power supply line is connected to the control main board of the controller by soldering. Before soldering and fixing the line of the electric actuator to the control main board of the controller, it is necessary to test the enabling of the assembled electric actuator to avoid the problem of disassembling the line from the control main board of the controller when unqualified products appear. The existing test power-on method is that the control main board of the controller is connected to a wire clamp through a circuit, and then the valve electric actuator is clamped by the wire clamp and powered on. The disadvantage of this test method is that the wire clamps are in a movable state, and it is easy to have an open circuit problem when the wire clamps contact each other. In addition, the on-off state of the wire clamps is not easy to judge. Although there is a power-on indicator light, there is still a certain test risk when the power-on indicator light is damaged.

Several conductive contacts are arranged in the lower concave pressing block. The conductive contacts and the controller are connected to a power supply through a circuit. Two screw sleeves are symmetrically screwed and installed on the top surface of the test bench. The positioning pin is fixedly installed on the top of the screw sleeve.

[0005] The wire splitter is composed of a bracket, wire clamps, and wing plates. Three wire clamps are fixedly installed on the top of the bracket. Two wing plates are fixedly installed on both sides of the bracket. Through holes matching the positioning pins are arranged on the wing plates.
