Abstract

The utility model relates to a mechanical timed switch socket, which is composed of a shell body 1, a single-knife double-throw switch 2 which is arranged on the shell body 1, a protective tube 3, an indicating lamp 4 and a socket 5. The structure of the utility model is characterized in that a mechanical timer 6 is also fixedly arranged on the shell body 1, a phase wire of an external power supply is connected with a throw knife of the single-knife double-throw switch 2 by the protective tube 3, the other two connection points of the switch 2 are respectively connected with a phase wire of the socket 5 directly or by the mechanical timer 6, and a zero wire in the socket 5 is directly connected with a zero wire of the external power supply. The utility model not only can be used as a common socket but also has the timed 'opening' or timed 'closing' functions. The utility model has the advantages of simple structure, safe and convenient operation, and low cost; furthermore, the utility model is suitable for wide wage families.

Description

The mechanical timing switch socket

The utility model relates to a kind of socket of belt switch, and particularly a kind of mechanical timing switch socket belongs to the electric connector technical field.

At present, in reality production and life, people be unable to do without machinery equipment and electric equipment products, and supply socket is the electrical accessory product that must use.No matter the supply socket of prior art is single system or multi-modulation scheme, no matter is fixed or movable type, does not all have the timing switch function.Though some household appliances itself has the function of remote control switch, this remote control switch is an electronic switch, does not have real power cutoff, and has complex structure, cost height, uneasy congruent shortcoming.

The purpose of this utility model, be for provide a kind of simple in structure, with low cost, regularly open or close, the mechanical timing switch socket of safe ready.

The purpose of this utility model can reach by taking following measure: the mechanical timing switch socket, form by housing 1 and the single-pole double-throw switch (SPDT) 2, protective tube 3, indicator light 4 and the socket 5 that are arranged on the housing 1, its design feature is: also fixedly install mechanical timer 6 on the housing 1, the phase line of external power supply connects the cutter of throwing of switch 2 by protective tube 3, two tie points of other of switch 2 respectively directly or the phase line by described mechanical timer 6 gang sockets 5, socket 5 interior zero lines directly are connected with the zero line of external power supply.

The purpose of this utility model also can reach by taking following measure:

Described mechanical timer 6 is in series by timer A, timer B, wherein the outer connecting line of timer A is removed, opening an aperture near the inner contact place, fix a metal contact 7 on former insulation adhesive tape, the former contact of metal contact 7 and close metal contact 7 is respectively welded a lead-in wire and is connected a tie point of switch 2, the phase line of socket 5 respectively.

Timer A, timer B are common commercially available mechanical type fan timer.

The method of modifying of timer A is as follows: two connecting lines that the prior mechanical timer exposes are dismantled, opening an aperture near near the position of contact, the inside, insert again to connect the metal contact and should connect contact and be fixed on the insulation adhesive tape, again connecting the lead-in wire of burn-oning on contact and the contact, form new input/output line then near the connection contact.When timer was in " pass ", input/output line was connected, with the original functions reversed of timer, and the actual connected state that is in of timer; And when timer was in " leading to ", input/output line disconnected, the actual off-state that is in of timer; When timer was in " cancellation ", timer was in complete off state; Reached the handoff functionality opposite with general timer.

The utility model single-pole double-throw switch (SPDT) can be set " regularly ", " leading directly to " two states.

The utlity model has following five kinds of functions:

1. regularly/lead directly to and freely switch

When single-pole double-throw switch (SPDT) placed " leading directly to " position, by timer, the utility model did not use as common socket external power supply; When single-pole double-throw switch (SPDT) placed " regularly " position, external power supply was by timer, and the utility model uses as the timing socket.

2. realize regularly " opening ", regularly " pass "

Under " regularly " state, timer A dextrorotation is t extremely sometime ₁, timer B dextrorotation goes to t sometime ₂, and t ₂＞t ₁, socket just can be at t ₂-t ₁Connect in time, through t ₂Automatically shut down after time.

3. realize regularly " pass "

Under " regularly " state, timer A places " connection " position, and timer B dextrorotation goes to t sometime, and promptly socket automatically shuts down behind time t.

4. realize regularly " opening "

Under " regularly " state, timer A is threaded to t sometime, and when timer B was rotated counterclockwise to " cancellation " position, socket was being opened (and till can opening to artificial shutoff single-pole double-throw switch (SPDT)) automatically always behind the time t.

5. realize the interrupt timing function

Under " regularly " state, when timer A is threaded to " cancellation " position, can thoroughly turn-off the plug-in source, socket does not have.

The utlity model has following outstanding advantage:

Both can be used as common socket and used, had regularly " opening " or the function of " pass " regularly again, simple in structure, easy to use safe, with low cost, be applicable to vast salary family.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is the outline drawing of the utility model embodiment 1.

Fig. 2 is the electrical schematic diagram of the utility model embodiment 1.

Fig. 3 is the partial cutaway diagrammatic sketch of the utility model through the timer A of repacking.

Fig. 1, Fig. 2 and Fig. 3 constitute embodiment 1 of the present utility model.As can be seen from Figure 1, present embodiment is made up of housing 1 and the single-pole double-throw switch (SPDT) 2, protective tube 3, indicator light 4, socket 5, mechanical timer 6 and the circumscripted power line 8 that are arranged on the housing 1, and described mechanical timer 6 is in series by timer A, timer B; As can be seen from Figure 2, the phase line of circumscripted power line 8 connects the cutter of throwing of switch 2 by protective tube 3, two of other of switch 3 connect sends out the some phase utmost point by described mechanical timer A, timer B gang socket 5 or directly connect the phase utmost point of socket 5, the zero line of the direct gang socket 5 of the zero line of circumscripted power line 8 respectively; As can be seen from Figure 3, the outer connecting line of timer A is removed, opening an aperture near the inner contact place, on former insulation adhesive tape, fix a metal contact 7, as output, the input of timer A, described input, output connect a tie point of switch 2, the phase line utmost point in the socket 5 respectively respectively in original contact of metal contact 7 and close metal contact 7.Timer A, timer B are common commercially available mechanical type fan timer in the present embodiment.

From figure as can be known, when timer A is in " pass ", the conduction that the insulating cement bar drive to be implanted is touched 7 and is contacted with original conductive contact, therefore electric current can pass through timer A, when timer A was in " opening ", the insulating cement bar drove described conductive contact blade 7 and disconnects with original conductive contact, and electric current can not pass through timer A, socket power is turned off, and has reached the handoff functionality opposite with the timer original function.
