Abstract

The invention provides a fuse assembly supporting hot plugging. The fuse assembly comprises a housing, a fuse, and two contact sheets. The contact sheets are electrically connected with the connecting ends of the fuse and are used for being in contact with two contact ends of a pedestal assembly in a plugging manner to form electrical connection. The invention also provides a connector equipped with the fuse assembly supporting hot plugging. According to the fuse assembly supporting hot plugging and the connector, the contact ends are not in direct contact with the connecting ends of the fuse in the plugging manner. Thus, high temperature generated by sparks in a hot plugging process cannot directly damage the connecting ends of the fuse and does not influence the normal electrical connection performance of the contact sheets such that the hot plugging function of the fuse assembly is achieved. Each of both ends of each fuse clamp is provided with multiple contact ends so that connecting resistance is further reduced. Each fuse clamp is sleeved by a clamp sleeve. The clamping arms of the contact ends of the pedestal assembly are sleeved by contact end clamp sleeves such that clamping force is reinforced and more reliable electrical connection is achieved.
