Description

Multifunctional safe protection socket

Technical field

The utility model relates to a kind of multifunctional safe protection socket.

Background technology

The present socket that uses; only play the effect of power connection and disconnection; use both inconvenient; cause the generation of personal electric shock casualty accident again easily,, plug and unplug plug danger close again especially in inflammable, explosive place; owing to the reeve of socket, plug, extract; cause spark to spatter outward, accidents such as initiation fire, blast, it is that socket does not possess failure protection function that its main cause takes place.The safeguard protection performance that socket is maximum on the market only has automatic overload protection, short-circuit protection, the surge voltage function of protection automatically.Its deficiency is: its protection system just is installed in a fuse in the place in circuit of plug or socket, and when faults such as circuit generation overload or short circuit, the blowout in the fuse is to play the effect of protection; But after fault was got rid of, the user can buy and install a fuse bigger than rated current, directly connected with thick copper lines even, so just lowered even do not had the function of safeguard protection, had increased potential safety hazard widely; After the outage of breaking down, single switch or button still are in the state of connection, can not automatic disconnection, be easy to after fixing a breakdown, take place again other electric shock accidents; Socket is a mobile, is assembled on the socket cover, and in any case tight, always apertured between socket and the socket cover, the water on the socket cover is easy to seepage and advances in the socket, causes the generation of accident such as short circuit.Therefore, the protective effect that this socket rises is limited, and its security performance can not play the purpose of real protection personal safety.

Summary of the invention

The utility model purpose provides a kind of multifunctional safe socket, for the Electrical Safety of various power consumption equipments provides protection.

For achieving the above object; the utility model adopts following technical scheme: a kind of multifunctional safe socket; comprise socket and socket secure protection mechanism; it is characterized in that the socket secure protection mechanism comprises the bakelite base; the inlet wire Connection Card; fixed contact; moving contact; switch knob; switch operating mechanism; zero sequence current mutual inductor; signal processing and amplification circuit piece; tripping coil release and outlet Connection Card; the inlet wire Connection Card is installed on the bakelite base; riveting has fixed contact on the inlet wire Connection Card; the action of moving contact is by the connecting and disconnecting of switch knob and switch operating mechanism realization and fixed contact; moving contact is connected with coil on the zero sequence current mutual inductor; the other end of coil is connected with the outlet Connection Card on the zero-sequence transformer; the outlet Connection Card is connected with reed on the socket; zero sequence current mutual inductor is connected with amplification circuit with signal processing; integrated circuit is connected with the tripping coil release; the tripping coil release is connected with switch knob, to realize the automatic control of action.

Advantage of the present utility model: adopt the multifunctional safe protective device, can set up the bridge of a safety between electrical appliance and power supply, be a kind of multifunctional safe protection socket with kinds of protect functions such as overvoltage protection, low-voltage action protection, electrical shock protection, leak electricity short-circuit protection, anti-lightning strike protection, the dangerous voltage of anti-surge protection, limiting short-circuit current protections in one; When breaking down, when above seven faults promptly occurring and causing accident occurring, the utility model will be cut off the electricity supply automatically, and only after having got rid of fault fully, the switch knob of multifunctional safe protection socket just can push the position of connection, has guaranteed the safety of electricity consumption; This multifunctional safe protection socket also can be used as the fault test set of power consumption equipment circuit; detect each power consumption equipment security performance; also can play detection to faults such as the short circuit in the circuit, scarce line, phase shortage, broken strings; can eliminate potential faults, play the effect that prevents trouble before it happens, provides for a rainy day.Just in case water is arranged on the socket cover, needn't worry also that water can leak in the socket, because this socket cover is an integral body, each slot all is higher than the plane of socket cover, goes so water is not easy to leak in the socket.

Description of drawings

Accompanying drawing is the structural representation of a kind of embodiment of the utility model multifunctional safe protection socket secure protection mechanism.

Embodiment

As shown in drawings; this multifunction protection mechanism comprises bakelite base 1; on a bakelite base, inlet wire Connection Card 6 is installed; the inlet wire Connection Card is connected with power line; riveting has the fixed contact 7 of a silver contact on the inlet wire Connection Card; fixed contact is used for having the moving contact 8 of contact to be connected with riveting; the action of moving contact is by switch knob 9 and the connecting and disconnecting of switch operating mechanism 10 realizations with fixed contact; moving contact is connected with coil on the zero sequence current mutual inductor 11; the other end of coil is connected with outlet Connection Card 2 on the zero-sequence transformer; the outlet Connection Card is connected with reed on the socket; zero sequence current mutual inductor is connected with amplification circuit 4 with signal processing; integrated circuit 4 is connected with tripping coil release 5; the tripping coil release is connected with switch knob 9; to realize the automatic control of action, between two outlet Connection Cards, also be connected to a fast break device 3, to realize quick closedown power supply manually.This socket cover is an integral body, and each slot all is higher than the plane of socket cover, and water is not easy to leak in the socket and goes.

During use, the plug of socket need only be connected on the power supply, the plug of various power consumption equipments is inserted in the slot hole of socket successively, the position that switch knob 9 is pulled out out (flag bit of the I on the socket cover) gets final product energized then; When needing outage, only need switch knob is pulled out the position (flag bit of the O on the socket cover) of closing, or the button that clicks fast break device 3 gets final product deenergization.
