Description

Technical Field

[0001] The utility model relates to the technical field of power distribution switches, in particular to an anti-electric shock power distribution switch. Background Art

[0002] A distribution switch is a component in electrical equipment that switches current on and off. It is widely used in electrical systems in homes, businesses, and industries, distributing, controlling, and protecting electrical systems.

[0003] Typically, a distribution switch, also known as a circuit breaker, is composed of a contact system, an arc extinguishing system, an operating mechanism, a tripping mechanism, a housing, and the like. Existing distribution switches are generally lever-type, with the rear end of the lever connected to the tripping mechanism, and the front end of the lever extending outside the switch housing through a gap at the front end of the switch housing. Since a portion of the lever is exposed and there is a lack of a seal between the lever and the opening at the front end of the switch housing, there is a chance of conduction due to water, which affects personal safety and requires improvement. Utility Model Content

[0004] In order to solve the problems mentioned in the background technology, the purpose of the present invention is to provide an anti-electric shock distribution switch.

[0005] In order to achieve the above objectives, the technical solution of the utility model is:

[0006] A power distribution switch for preventing electric shock includes a switch housing, wherein the front end of the switch housing is provided with an arched accommodating cavity, a cylinder is fitted in the accommodating cavity, a hook plate for connecting a tripping mechanism is provided on the circumferential surface of the cylinder, and special-shaped holes are provided at both axial ends of the cylinder, and circular holes are provided in the switch housing corresponding to the special-shaped holes, a special-shaped column is tensionedly connected in the special-shaped hole, one end of the special-shaped column facing away from the special-shaped column on the opposite side is fixedly connected to a round shaft rod, the round shaft rod is fitted in the circular hole, and one end of the round shaft rod facing away from the round shaft rod on the opposite side is vertically fixed to a connecting arm, and a toggle rod is commonly sleeved on the two connecting arms.

[0007] Furthermore, the toggle rod tensioning sleeve is arranged on the connecting arm.

[0008] The beneficial effect of the present invention is that a cylinder is used to replace the original lever, so that the front end of the switch housing is no longer provided with an opening, but only circular holes are provided on both sides of the switch housing, and round shaft rods are assembled in the circular holes. Compared with the traditional lever-type distribution switch, the probability of moisture entering the inside of the switch housing is greatly reduced, and the possibility of electric shock is reduced.
