Abstract
The utility model discloses a leakage protection socket which comprises a surface cover, a top cover, a circuit board, magnet rings, coils and pins. The top cover is located between the surface cover and a lower cover. The circuit board is located in the lower cover. The magnet rings, the coils, and the circuit board are connected together through the pins. The magnet rings with low thickness are selected. The leakage protection socket shortens the thickness from the front side to the back side, saves the space, resolves the problem of wiring inconvenience, and is convenient to construction.
Description
Technical field
The utility model relates to a kind of socket, particularly relates to a kind of earth leakage protective socket.
Background technology
Socket has referred to the insertable seat of one or more circuit connections, can insert various wiring by it, is convenient to connect with other circuit.Supply socket is the electric equipment that power interface is provided for household electrical appliance, is also in design of residence, to use more electrical accessory, and it and people's life have ten close relationships.Between the front-back of existing socket, thickness is dark, and in the more shallow construction site of the magazine degree of depth, magazine internal wiring is very inconvenient.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of earth leakage protective socket, and its conserve space has solved the problem of wiring inconvenience, constructability.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of earth leakage protective socket; it is characterized in that; it comprises cover, upper cover, wiring board, magnet ring, coil, contact pin; upper cover is between cover and lower cover; wiring board is positioned at lower cover; between magnet ring, coil and wiring board, all connect by contact pin, magnet ring is selected the magnet ring that thickness is shallow.
Preferably, the side of described lower cover is provided with auxiliary connection hole.
Preferably, described cover is provided with button.
Preferably, described button comprises testing button and reset button.
Preferably, one end of described contact pin is connected with coil, and the other end of contact pin is connected with the pad of wiring board.
Positive progressive effect of the present utility model is: the utility model shortens the thickness of socket front-back, and conserve space, has solved the problem of wiring inconvenience, constructability.
Brief description of the drawings
Fig. 1 is the perspective view of the utility model earth leakage protective socket.
Fig. 2 is the planar structure schematic diagram of the utility model earth leakage protective socket.
Fig. 3 is the structural representation of wiring board, magnet ring, coil in the utility model.
Fig. 4 is the structural representation of cover in the utility model.
Fig. 5 is the structural representation of lower cover in the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figures 1 to 5; the utility model earth leakage protective socket comprises cover 1, upper cover 2, wiring board 3, magnet ring 4, coil 5, contact pin 9, lower cover 8; upper cover 2 is between cover 1 and lower cover 8; wiring board 3 is positioned at lower cover 8; between magnet ring 4, coil 5 and wiring board 3, all connect by contact pin 9, magnet ring 4 is selected the magnet ring that thickness is shallow.One end of contact pin is connected with coil, and the other end of contact pin is connected with the pad of wiring board, connects by the mode of soldering.
The side of lower cover 8 is provided with auxiliary connection hole 6, one or more common sockets can be connected to auxiliary connection hole like this, can make the common socket also can be with creepage protection function.Cover 1 is provided with button 7, like this handled easily.Button comprises testing button and reset button.
In the time that the plug of electrical equipment is inserted on the utility model earth leakage protective socket, if user thinks deenergization, under normal circumstances, client will pull up plug; If the utility model earth leakage protective socket has been installed, client only need just can deenergization by testing button.Want to reclose power supply, only need to, by reset button, just can switch on power, and not need to pull up plug, can avoid so repeatedly plugging plug product is damaged.
Under normal circumstances, the electric current on zero line and live wire equates, electric current flows into electric equipment products from live wire, then goes back from zero line upper reaches.To be exactly some electric current of electric current of flowing into electrical equipment flow to the earth through human body or other conductors to leaky has got on.Cause the electric current on zero line and live wire unequal; the utility model earth leakage protective socket puts a magnet ring on electric input zero line live wire, and in the time there is electric leakage, magnet ring can produce induced current, then passes through amplified current; export a current signal, make relay open circuit.
The earth leakage protective socket pre-buried degree of depth is below less than 25mm, is even less than some common sockets, is mainly by before wiring board is contained in, and after magnet ring and coil be contained in, the connecting mode of wiring board and magnet ring and coil contact pin connected mode.
Feature of the present utility model is as follows: one, and wiring board originally has two, is separately positioned on the front and rear of socket, by improving, wiring board changes one into, is arranged in the middle of the upper cover and middle frame of socket now, utilize fully the space of socket, make it to reach the object of reduced volume.Two, select the magnet ring that thickness is shallow, simultaneously, magnet ring originally is directly arranged in the circuit board, change now by contact pin magnet ring is connected with wiring board, the wiring board area that former like this cause magnet ring takies can be used for arranging other electronic components, and originally magnet ring, coil are directly installed on wiring board, takes up room so large and thickness is large.Three, same, coil originally is directly arranged in the circuit board, changes now by contact pin coil is connected with wiring board, and the wiring board area that former like this cause coil takies can be used for arranging other electronic components.
The utility model shortens the thickness of socket front-back, and last thickness is 25mm, and conserve space has solved the problem of wiring inconvenience, constructability.Cover the inside may have a lot of electric wires, words as very large in the pre-buried part of fruit product can cause product install after with metope injustice.Pre-install the degree of depth below and reduced, can be very convenient when erector's wiring, can not produce can difficulty.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
