The technical solution of the utility model is: it comprises base, insulated shell, fuse, support, current collection device and cable, support is fixed on the base, fuse is rack-mount, and form an independently insulated cavity by insulated shell, current collection device is fixed on the base by bolt, nuts and washers, and the two ends of cable are fixed on the support by bolt, nuts and washers respectively; Described current collection device comprises pedestal, axis, elastic bearing, slipper, pedestal is fixed on the base by bolt, nuts and washers, bearing seat is fixed on the pedestal, elastic bearing is fixed on the bearing seat, axis is installed on the elastic bearing by its supported hole, rollback control stalk, left-handed torque spring, the support of carbon piston shoes, dextrorotation torque spring are installed on the axis from left to right, and slipper is by being bolted on the pedestal; Support rotational angle in order to limit the carbon piston shoes, guarantee that the piece that flowed on the carbon piston shoes reliably contacts with the 3rd rail, between slipper and the support of carbon piston shoes, be provided with the buffering bolt and regulate bolt; Fuse is connected with current collection device by cable and bolt, nut, packing ring; Under the effect of left-handed torque spring and dextrorotation torque spring, the dynamic stability that is flowed is guaranteed in being flowed piece and can contact with the 3rd rail all the time on the carbon piston shoes.

On the described insulated shell transparent window is installed, is beneficial to observe the mode of operation of fuse by transparent window.

In order to compensate wheel operation back abrasion loss, the position that current collection device is installed on the base is provided with the guiding rack-plate, and the regulated quantity of guiding rack-plate is 4mm-40mm.

For easy to operate, the end of rollback stopping bar is provided with operating handle.

Described elastic bearing is made up of resilient sleeve, lining and rubber strip, and rubber strip is between resilient sleeve and lining; In order not only to satisfy requirement of strength but also satisfy toughness reguirements, the suitable aluminium alloy of resilient sleeve is made.

Described packing ring is a toothed washer.

The utility model integrates fuse and pantagraph current collector, can conserve space, and convenient for maintaining, the automatic and adjustable when contact pressure of current collection device and the 3rd rail moves has simultaneously been guaranteed the working stability of pantagraph current collector.
