Description
Technical field
The utility model relates to a kind of overcurrent earth leakage protective socket.
Background technology
At present, in the production process of appliance socket, produce leaky for avoiding circuit, protection user's personal safety, socket inside all is provided with earth leakage protective device; And be the overcurrent of avoiding circuit, generally only be provided with single fuse in the socket.Yet; fuse is to fuse by the electric current heating functioin to reach the overcurrent protection of circuit; but occur to blown fuse from the over-current phenomenon avoidance of circuit; need during this time through after a while; during this period of time; fuse does not still have real-time overcurrent protection to circuit, and its over-flow protecting effect is relatively poor, and security reliability is bad.In addition, after blown fuse, can only lean on manual replacing again, troublesome poeration has certain danger in the occasion of high voltage, big electric current.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of over-flow protecting effect good, safe and reliable, easy to operate overcurrent earth leakage protective socket.
Goal of the invention of the present utility model is achieved in that a kind of overcurrent earth leakage protective socket; comprise be located on the load circuit and interconnective earth detector be connected contact; earth detector is connected with electrical network; it is characterized in that: be provided with magnetic latching relay and the overcurrent detecting device that is connected with load circuit in the described overcurrent earth leakage protective socket, the contact-making switch of magnetic latching relay inserts load circuit.
The output of described overcurrent detecting device is provided with the threshold values discriminating processing device that is connected with the output of earth detector, be provided with the trigger switch unit between the signal output part of threshold values discriminating processing device and the magnetic latching relay, the voltage input end of threshold values discriminating processing device is connected with a voltage regulation filtering unit, and the voltage regulation filtering unit also is connected with trigger switch unit, earth detector and overcurrent detecting device respectively.
Described trigger switch unit is provided with two output contacts, and two output contacts are connected with starting as propelling coil with the pass action propelling coil of magnetic latching relay respectively.
Be provided with touch-switch and pulse-triggered module between described voltage regulation filtering unit and the trigger switch unit successively, the pulse-triggered module also is connected with the voltage regulation filtering unit.
Described overcurrent detecting device comprises inspection streamline circle that is located on the load circuit and the transformation coil that is connected with threshold values discriminating processing device.
The utility model improves the band earth leakage protective socket of prior art; when overcurrent or leaky appear in circuit; magnetic latching relay promptly cuts off and loop-coupled contact-making switch according to the signal output of threshold values discriminating processing module; electrical appliance and loop have effectively been protected; overcurrent earth leakage protective is effective, and is safe and reliable.And magnetic latching relay can reclose load circuit by the instruction manipulation to touch-switch and pulse-triggered module, and practical operation is convenient.
