The invention discloses a low-voltage multipurpose short-circuit connector, comprising fixing clamps, flexible jumping wires and a short-circuit connecting member, wherein each fixing clamp comprises a conductive fixing member and a conductive adapting member; each of the flexible jumping wires is a conductive braided strap; each of two ends of each conductive braided strap is provided with a connecting hole; the short-circuit connecting member comprises a back plate which is made of a material with an insulating arc-isolating effect and is used for fixation; the back plate is provided with installation holes which are adapted to fuse wires with different pitches and the size of a base; the fuse wires are arranged on the base. In the field application, the low-voltage multipurpose short-circuit connector disclosed by the invention can be used as an effective measure for quickly repairing and recovering electric power after switches with different models and different specifications are in fault, and can also be fixedly used as the leading end of a short-circuit connection grounding wire. According to the low-voltage multipurpose short-circuit connector, not only are the problems that the rush repairing time is long due to the fact that a switch is not matched, and the power fault range is large solved, but also the problem that the leading end of the overhauling grounding wire of most switches cannot be installed is solved, and the operation efficiency and power supply reliability are improved.
