Description
Technical field
The utility model relates to power supply changeover device, specifically, relates to the high power supply changeover device of a kind of security performance.
Background technology
At present, power supply changeover device on the market has many types, but this all is to be in "on" position after connecting with the mains for existing power supply changeover device, there is certain danger in it, if still there is the possibility of getting an electric shock because of carelessness in the user, especially for the strong child of curiosity,, might bring danger owing to energising if they insert with metal object in the jack of power supply changeover device because of curiosity.Therefore, how to address the above problem, become problem demanding prompt solution.
The utility model content
The utility model is to provide a kind of high power supply changeover device of security performance that can be automatically under non-working condition disconnects with extraneous power supply simple in structure, safe in utilization.
For achieving the above object, the utility model has adopted following technical scheme:
The power supply changeover device that a kind of security performance is high, the tie point that comprises converter body and be used for being connected with alternating current, it is characterized in that: in described converter body, be provided with electric shock piece, inserted block and and be used to back-moving spring that the electric shock piece is disconnected with tie point under non-working condition, the jack that described inserted block is provided with locating piece and is used for being connected with a plug, described electric shock piece is provided with groove and is provided with and is used for the contact that is connected with described tie point, and the locating piece of described inserted block is located on the groove of electric shock piece.
Described electric shock piece also is provided with and is used for the projection that cooperates with plug, and described projection is positioned at the jack of inserted block.
Described inserted block is two, is arranged with two grooves on the described electric shock piece and is arranged with two projections.
The utility model is owing to adopted said structure, in described converter body, be provided with the electric shock piece, the back-moving spring that inserted block and is used to make the electric shock piece to disconnect with tie point under non-working condition, the jack that described inserted block is provided with locating piece and is used for being connected with a plug, described electric shock piece is provided with groove and is provided with and is used for the contact that is connected with described tie point, the locating piece of described inserted block is located on the groove of electric shock piece, therefore plug is after inserting jack, have only when plug and touching the electric shock piece and the electric shock piece is produced under the effect situation of power, the piece that gets an electric shock this moment just can move under the effect of the power of plug and finally be connected with tie point, thereby realize the utility model and extraneous power turn-on, promptly under user mode, the utility model is connected extraneous power supply; After pulling the plug out of the socket, plug disappears to the effect of the power that the electric shock piece applies, under the reset response of back-moving spring, back-moving spring will make the electric shock piece leave tie point, the piece that promptly gets an electric shock this moment is not connected with tie point, and power supply changeover device auto power off of the present utility model at this moment is promptly under non-working condition, power supply changeover device auto power off of the present utility model, thus the utility model is simple in structure, cost is low, safe in utilization.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of the high power supply changeover device of a kind of security performance of the utility model.
Fig. 2 is the structure chart of the electric shock piece of the high power supply changeover device of a kind of security performance of the utility model.
Fig. 3 is the structure chart of the inserted block of the high power supply changeover device of a kind of security performance of the utility model.
Embodiment
As shown in Figure 1, it is the schematic diagram of the high power supply changeover device of a kind of security performance of the utility model.The power supply changeover device that a kind of security performance is high, the tie point 14 that comprises converter body 1 and be used for being connected with alternating current.In the technical program, in converter body 1, be provided with electric shock piece 12, the back-moving spring 13 that inserted block 11 and is used to make electric shock piece 12 to disconnect with tie point 14 under non-working condition, wherein inserted block 11 is two, the jack 111 that inserted block 11 is provided with locating piece 112 and is used for being connected with a plug, on electric shock piece 12, be provided with groove 122, the contact 121 that projection 123 and being used for is connected with tie point 14, the locating piece 112 of inserted block 11 is located on the groove 122 of electric shock piece 12, therefore locating piece 112 can play positioning action, electric shock piece 12 can move along the direction of locating piece 112 under the effect of power.
As shown in Figure 2, it is the structure chart of the electric shock piece of the high power supply changeover device of a kind of security performance of the utility model.The piece 12 that gets an electric shock as can be seen is provided with two contacts 121 in the side towards tie point 14 of electric shock piece 12, also is arranged with groove 122 on electric shock piece 12, and a side that cooperates with jack 111 at electric shock piece 12 is provided with two projections 123.
