Abstract

The invention relates to a clamp for installing a moving contact of a handcart of a breaker. A rear supporting plate is provided with a segment of threaded through-hole equipped with a screw; the front end surface of the screw is connected to a smooth bar with a relatively small diameter; a movable outer mould and inner mould sleeve the smooth bar; the front end surface of the outer mould is provide an inner cavity allowing the inner mould to enter; the front segment of the smooth bar is provided with a thread, wherein the outer diameter of the thread is lower than the inner diameter of the inner mould, and the thread is equipped with a nut for limiting the front end surface of the inner mould; the front end surface of the outer mould can limit a rear end surface of a tulip contact; the front end surface of the inner mould is limited by an end surface of an installation end of a movable contact arm; and the inner mould can enter and open the inner cavity of the tulip contact through extrusion. The inner mould is arranged to open the inner cavity of the tulip contact, and the tulip contact is installed on the movable contact arm via pushing force. The clamp is convenient to install, and is labor-saving and time-saving.

Description

technical field [0001] The invention relates to a fixture for installing a moving contact of a handcart of a circuit breaker, which is used for installing the plum blossom contact on a moving contact arm. Background technique [0002] The moving contact of the circuit breaker includes a moving contact arm and a ring-shaped plum blossom contact for being sleeved on the moving contact arm. The front end of the moving contact arm is provided with a ring-shaped slot. Has raised shrapnel. When installing, it is necessary to put the plum blossom contact on the moving contact arm, and clamp the shrapnel in the slot of the moving contact arm. [0003] However, due to the large elastic force of the shrapnel, it is laborious and time-consuming to install. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a handcart moving contact installation jig which can facilitate the installation of the moving contact and save time and...
