Abstract

The invention provides an automatic testing device for a contact resistor made of an electrical contact material and relates to a testing device for the contact resistor made of the electrical contact material. The invention solves the problem of the absence of the testing device for the contact resistor made of the electrical contact material which is capable of automatically controlling a contact pressure and supporting multi-contact continuous measurement. Longitudinal and horizontal sliding tables are both arranged on an upper surface of a machine base; the longitudinal sliding table is connected with the horizontal sliding table through a horizontal and longitudinal sliding table connector; a vertical sliding table is fixedly arranged at the upper end of the horizontal and longitudinal sliding table connector; a pressure sensor is fixedly arranged on the vertical sliding table; the two ends of a pressure sensor connector are respectively connected with an elastic element and the pressure sensor; a probe is assembled on a probe clamp connector through a probe clamp; a multi-contact clamp is fixedly arranged on the upper surface of the longitudinal sliding table; and a to-be-tested contact is fixedly arranged on the multi-contact clamp. The automatic testing device realizes the automatic control on a contact force of a contact and the continuous measurement for a multi-contact contact resistor and has the advantages of measuring accuracy, convenience in operation and high efficiency.

Description

technical field [0001] The invention relates to a device for testing the contact resistance of electric contact materials. Background technique [0002] Electrical contact materials for switches, relays, electrical connections and electrical plug-in components, also known as electrical contact materials. Generally, there are two types of contact materials for strong current and contact materials for weak current. Electrical contact materials are key functional materials and important basic materials for power generation, transmission and distribution, and power consumption equipment in my country. They are used in a wide range of fields, and their product quality or technical level directly affects or even restricts high-end products in many fields and industries in my country. Product Development. [0003] The so-called contact resistance refers to the obstruction of the current flowing by two closely contacted junctions, whether it is a fine IC socket or a thick bolt-fixe...
