Abstract

The invention discloses a multi-pole fuse switch, which is characterized in that a plurality of fuse shells are fixedly connected through a fixing structure, and the fixing structure comprises a first locking assembly arranged between one ends of the plurality of fuse shells and a second locking assembly arranged between the other ends of the plurality of fuse shells. According to the multi-pole fuse switch, two adjacent fuse shells in the multi-pole fuse switch are firmly locked by the first locking assembly and the second locking assembly respectively, a loosening phenomenon among the fuse shells is prevented, the first locking assembly and the second locking assembly adopt a mode that a plurality of U-shaped lock catches are clamped with a plurality of slotted holes, the installation stability is good, and the service life of the multi-pole fuse switch is prolonged. According to the utility model, a plurality of fuse shells are fixedly connected, a traditional rivet installation mode is avoided, the installation process is simplified, the installation difficulty is reduced, the assembly efficiency is improved, the production cost is reduced, the assembly and use of multi-pole fuse switch products with different specifications are well met, and the installation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to a multi-pole fuse switch. Background technique [0002] The fuse switch is an electrical appliance that plays a role in safety protection. It can be used for isolation protection between the power supply and the load. It is also widely used for the protection of power grids and electrical equipment. It is one of the most commonly used protection devices. When the power grid or the line of the electrical equipment is short-circuited or overloaded, the fuse switch can automatically cut off the circuit to avoid damage to the electrical equipment and prevent the accident from spreading. [0003] Fuse switches can be divided into single-pole fuse switches and multi-pole fuse switches according to wiring requirements. Multi-pole fuse switches have 2P, 3P and 4P specifications. The fuse switch is assembled by rivet riveting. It is necessary to preset multiple rivet holes on multiple fuse...
