Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches, and more specifically, to an isolating switch housing. Background Art

[0002] Isolating switch is a switch device that is mainly used for "isolating power supply, switching operation, connecting and disconnecting small current circuits" and has no arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions within a specified time. For example, the prior art publication number (CN214588569U) describes a new type of isolating switch device for power equipment. The tip of the screwdriver is inserted into the operating hole and located in the groove on the vertical rod. The screwdriver is then pressed down with the inner bottom wall of the operating hole as a fulcrum. At this time, the vertical rod can move upward, and the vertical rod can drive the movable plate to move during the movement. The movable plate compresses the spring during the movement, and the vertical rod drives the clamping plate to separate from the wire. At this time, the wire can be taken out of the wiring port. After the maintenance is completed, the wire is placed between the clamping plate and the wiring plate. Then the screwdriver is released, and the clamping plate can be driven downward by the restoring force of the spring, thereby fixing the wire in the wiring port. The entire wiring process is simple and convenient. Since the elastic force of the spring will decrease after long-term use, the adjusting screw can be turned to move downward at this time. After the adjusting screw moves downward, the elastic force of the spring is increased.

[0003] When the above device is in use, the wire can be fixed in the wiring port by the restoring force of the spring. The entire wiring process is simple and convenient, which greatly improves the wiring efficiency. However, when the isolating switch housing is produced, workers are usually required to assemble the top and bottom housings together. During the assembly, professional equipment is required to lock and fix them. However, during the assembly, it is easy to become loose, which can easily affect the subsequent locking work.
