The invention discloses a PTC thermistor ceramic withstand voltage test device which comprises a base (1), a guide pillar (2), a transmission device (3) and a voltage control system. A lower test needle plate assembly is horizontally fixed to the base (1). The guide pillar (2) is vertically fixed to the base (1). A slidable upper test needle plate assembly and a positioning slide rail assembly where a test plate can be placed are connected to the guide pillar (2). A spring (4) is arranged between the positioning slide rail assembly and the base (1). The positioning slide rail assembly is arranged between the lower test needle plate assembly and the upper test needle plate assembly. The transmission device (3) is fixed to the upper test needle plate assembly through a transmission main shaft. The transmission device (3), the upper test needle plate assembly and the lower test needle plate are connected with the voltage control system through circuits. By means of the PTC thermistor ceramic withstand voltage test device, the withstand voltage test efficiency can be improved, the scrap phenomenon can be reduced, and cost can be reduced; maintenance and repair are convenient, operation is easy, and high universality, flexibility and rapidness are achieved.
Description
