Description
Technical field
The utility model relates to a kind of earth leakage circuit-breaker
Background technology
Present cabinet air-conditioner, household electrical appliance such as water heater all are to adopt the external power supply line directly to be inserted in power taking on the household socket, though this method is convenient and swift; But there are a lot of potential safety hazards; The one, open-wire line appears in the room, influence attractive in appearance, the 2nd, plug is often stirred and is caused loose contact to cause a lot of electric accidents easily; The 3rd, no any defencive function, safety does not have guarantee.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, the earth leakage circuit-breaker that a kind of electric leakage, electrical shock protection is provided and can in time breaks off.
For realizing above-mentioned purpose; The utility model adopts a kind of earth leakage circuit-breaker, comprises base, loam cake, operating grip, leakage tripping device, movable contact spring, static contact, arc control device, conducting system, spring, input, lead-out terminal, and this movable contact spring is arranged at the below of operating grip; And be connected on the base through spring; Operating grip passes the earth leakage circuit-breaker loam cake, and magnetictrip is arranged on the operating grip right side, and movable contact spring is connected on the base through guide rod; Extend to form terminals and arc end about the movable contact spring two ends; Terminals are connected with input terminal, and arc end extends upward and forms the obtuse angle and towards arc control device, and the static contact that is positioned at the movable contact spring lower end is connected with lead-out terminal and is fixed on the base.
Pass through improvements over the prior art; Movable contact spring is connected on the base through spring and guide rod, adopts floating lever rod formula and guide rod correcting, has improved contact pressure, breaking speed and make-break capacity; Secondly; The arc end of contact chip extends upward and forms the obtuse angle and towards arc control device, controlled spray arc district, has improved arc extinguishing ability and electric life.
The utility model further is set to: the parallel and oblique setting of some flash barriers on the arc control device, direction is towards the arc end of movable contact spring.
Through further improvement, reach the good effect of arc extinction performance to above-mentioned technology.
The utility model further is set to again: input, lead-out terminal adopt the screw crimping mode of connection.
Through the further improvement again to above-mentioned technology, screw adopts the crimping mode of connection to make wiring more firmly firm, can avoid inapplicable and high-power circuit of plugs and sockets and bad because of patching, the with the passing of time loosening serious accident that causes.
