Description

Technical Field

[0001] The utility model relates to the technical field of electric wire plugs, in particular to a plug mechanical strength extrusion testing device. Background Art

[0002] The wire plug is a very common electrical connection component. When the wire plug of an electrical appliance is inserted into a power socket, power can be supplied to the appliance so that the appliance can work normally. The wire plug is generally made of smooth plastic material. When the wire plug is transported or placed, once it is squeezed and stepped on, it is easy to cause the wire plug to deform, which will affect its use. Therefore, the mechanical strength test of the wire plug is required after it is produced.

[0003] The traditional way to test the wire plug is to use a squeeze plate to squeeze the wire plug from top to bottom, and manually add weights to the squeeze plate to increase the weight of the squeeze plate, thereby testing the mechanical strength of the wire plug. However, the weights are prone to rust if not stored properly, causing test errors, and the hand is prone to slipping during the process of manually adding weights, causing the weights to slip, thus causing injuries to the operator.

The controller controls the power unit, and the power unit drives the extrusion plate to squeeze the plug downward, so that the plug squeezes the extrusion disc downward, and the extrusion disc squeezes the sensing end of the pressure sensor. When the pressure value sensed by the pressure sensor reaches the pressure data input by the controller, the controller controls the power unit to stop, and the test is stopped. The test result is more accurate, the test error is reduced, and the operation is simple, and no harm is caused to the operator.
