Description

Multivoltage is selected socket

Affiliated technical field

The utility model belongs to a kind of power supply device spare, and the multivoltage that particularly relates to a kind of tape light is selected socket.

Background technology

The known power supply of often using 220V or 380V is aborning powered to equipment at present, and the switching that all needs under many occasions to carry out these two kinds of voltages is used.For example in the testing process of intelligent electrical apparatus release owing to successively all will detect, so often need between 220V and two kinds of voltages of 380V, switch use to the different product of its model.Be the binding post of directly drawing 220V and 380V respectively generally speaking from transformer, because the present standard plug that does not match with the intelligent electrical apparatus release power input terminal, the workman just needs directly to be connected with the intelligent electrical apparatus release power input terminal with the output wiring terminal of transformer in the operating process of reality.So not only connect not firm but also easy generation electric shock or power supply short circuit, further also had influence on production efficiency.Need two kinds of supply voltages to switch under the situation of the standard socket that uses and do not have to match for other, also have same problem with power device.

Summary of the invention

The utility model provides a kind of multivoltage that can conveniently carry out multiple supply voltage switching to select socket for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes the supply voltage input lead, also includes embedded power output terminal, indicator light window, switches display circuit device and socket insulation crust; Described switching display circuit device is arranged in the socket insulation crust, and described power output terminal is fixed in the jack of socket insulation crust; Described switching display circuit device includes the power output terminal of supply voltage input lead, light-emitting diode and the different voltages of output; the common port of described light-emitting diode links to each other with the power supply common port by a protection diode; through linking to each other with the input lead of the different voltages of power supply behind the current-limiting resistance, the power output terminal that described each supply voltage input lead is directly corresponding with each respectively links to each other the other end respectively.

Advantage and the good effect that the utlity model has are: the utility model is simple in structure, cost is low, realized that on same socket multivoltage is selected and indication.Owing to adopted the socket of embedded tape insulation shell, be connected more reliably between the power output terminal that not only makes intelligent electrical apparatus release power input terminal and other similar power devices and the corresponding power output terminal, and the fail safe of operation also increases greatly; Indicator light makes the mutual switching of multiple voltage become simply and clear and definite as the use of adding diverter switch, and its use will reduce the amount of labour of workman's operation, improve operating efficiency.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, select the embodiment of socket in conjunction with the detection of following intelligent electrical apparatus release with multivoltage now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, the insulation crust of socket device respectively by last piece 1 and following piece 3 be put together, copper output wiring terminal 2 has three, is separately fixed at down in three grooves 4 of piece 3, last three corresponding projections by 1 inner face of piece on the insulation crust compress; There is a big cavity at the middle part of piece 3 under the insulation crust, and the inside is placed with input power cord and switches the display circuit device, and the outer wall of piece 3 has the aperture 6 that runs through to be used to place light-emitting diode under the insulation crust.

See also Fig. 2, transformer T1 secondary coil has three exits to be respectively 380V, 220V and 0V; Interlock switch SB1 and SB2 go here and there respectively in 380V and 220V branch road; Be switching display circuit device in the frame of broken lines, light-emitting diode D1 and D2 that it includes two different colours are connected in parallel in 380V and the 220V branch road by resistance R 2 and R1 respectively, and the common port of light-emitting diode D1 and D2 connects 0V supply voltage input lead by diode D.For example red light emitting diodes D1 indication 380V green LED D2 indicates 220V; Three supply voltage input leads of 380V, 220V and 0V are welded on three copper output wiring terminals 2 successively.

Its operation principle is: SB2 disconnects when pressing SB1, and the 380V branch road is connected the 220V branch road and disconnected, and light-emitting diode D1 shows red; SB2 closure when disconnecting SB1,220V branch road are connected the 380V branch road and are disconnected, and light-emitting diode D2 shows green.

When selected voltage kind more than 3 kinds the time, selecting the structure of socket to increase lead-out terminal according to the voltage kind increase indicator light simultaneously.

See also Fig. 3, power input voltage is respectively V1, V2, V3 and COM common port, and wherein V1, V2, V3 receive four respective inputs selecting socket together through switching device shifter and COM common port, at last by selecting the output of socket output.Switching device shifter guarantees to have only one road voltage to connect at every turn, and corresponding indicator light D1, D2, D3 are bright simultaneously.
