Rapid testing device for contact resistance of welding type electrical contact element and testing method of device

Abstract

The invention discloses a rapid testing device for contact resistance of a welding type electrical contact element and a testing method of the device. The welding type electrical contact element comprises a first to-be-tested workpiece and a second to-be-tested workpiece, wherein the first to-be-tested workpiece comprises a first conductive substrate welded with a first sheet-shaped contact, and the second to-be-tested workpiece comprises a second conductive substrate welded with a second sheet-shaped contact; the device further comprises a clamping mechanism used for fixing the first to-be-tested workpiece, a clamping mechanism used for clamping the second to-be-tested workpiece, a force applying mechanism used for pressing the second to-be-tested workpiece on the first to-be-tested workpiece and a resistance testing mechanism used for testing a resistance value when the first to-be-tested workpiece and the second to-be-tested workpiece are in contact with each other in a extruded manner; one end of the resistance testing mechanism is electrically connected to the first conductive substrate, and the other end of the resistance testing mechanism is electrically connected to the second conductive substrate; and the first sheet-shaped contact and the second sheet-shaped contact are oppositely extruded. According to the device and the method, the detection efficiency of the contact resistance of the welding type electrical contact element can be improved, and the device and the method have the characteristics of being simple in structure and easy to operate.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a quick test device and a test method for the contact resistance of welded electric contact elements. Background technique [0002] Contact resistance is a very critical performance index of relay products. The stability of contact resistance and the size of contact resistance have a crucial impact on the performance of relay products; generally speaking, to detect the contact resistance of electrical contact components, it is necessary to The contact element products are assembled into finished relays, and then use a special resistance measuring device to test the contact resistance of the products, so the operation cycle is longer, and for parts processing enterprises, generally do not have the ability to assemble finished relays in the factory It is very inconvenient to operate, and it is impossible to monitor online in time whether the contact resistance index of the electr...
