Sliding contact structure realizing automatic adjustment on pressure of contact for low-pressure contactor

The utility model relates to a contact structure, in particular relates to a sliding contact structure realizing automatic adjustment on pressure of a contact for a low-pressure contactor. The sliding contact structure comprises a first static contact unit (401), a second static contact unit (402), a first movable contact unit (301), a second movable contact unit (302), an elastic mechanism (1), a conductive connecting rod (2) and an insulating rod (5). The elastic mechanism (1) is fixedly connected between the end parts of the first movable contact unit (301) and the second movable contact unit (302); the both ends of the conductive connecting rod (2) are connected with the first movable contact unit (301) and the second movable contact unit (302) through shafts; the insulating rod (5) is vertically and fixedly connected with the conductive connecting rod (2); and a compression spring structure is adopted as the elastic mechanism (1). The sliding contact structure provided by the utility model has high switching-on/off voltage grade, and has the function of automatically adjusting pressure between movable contacts and the static contacts so as to realize effective and compact contact between the contacts. The service life of the contacts can be prolonged by virtue of the self-cleaning function of the surfaces of the contacts.
