CN2298608Y - One-way timing socket - Google Patents

Abstract

The utility model discloses a one-way timing socket. A timer is added on an ordinary socket. The break time of the socket can be arranged through a contact (2) controlled by the timer. Timing can also not be implemented. The knob of the timer is adjusted to an ON position. Thus, the one-way timing socket can be used like the ordinary socket. When the timing is used, the knob of the timer is adjusted to a desired time scale. A power supply is cut off by the timing. No electricity is arranged on the socket. A current does not enter an electrical appliance. The knob is adjusted to an OFF position, the electrical contact (2) of the timer is disconnected. No electricity is arranged on the socket. The utility model which is suitable for domestic appliances, metallic outer shells and single-phase electric appliances which are frequently touched has the advantages of safety and convenience.

Description

Single-phase timing socket

The utility model relates to a kind of bipolar pair of member connecting device with protective earthing, especially the single phase poaer supply socket of being made up of plastic casing, fuse and socket.

Single phase poaer supply socket on the market when not operation, is long-term energising at present, home electric appliance plug is inserted on the socket, reach job requirement after, electricity still feeds in the machine, if under the situation of defective insulation or electric leakage, user or child and old man have a mind to or are not intended to hit, and the danger of electric shock is arranged; And, many household electrical appliances are arranged, when not using, its plug still is inserted in the supply socket, and some element is also in energising,, rectification circuit elementary and filter circuit etc. as transformation, consumed power shortens appliance life.

The purpose of this utility model provides a kind of socket that can regularly cut off the power supply, deenergization on the time of setting, and electricity does not enter in the electrical equipment; In use, blown fuse during the fault overcurrent plays protection and energy-conservation effect.

For achieving the above object, scheme of the present utility model is: on the input live wire of general single-phase socket, be connected in series a fuse and a timer-operated contact.Do not having under the situation of setting-up time, timer-operated contact disconnects, be to disconnect between live wire and socket, have only its closing of contact behind the setting-up time, socket is only electricity, uses by general single-phase socket, promptly reach setting-up time using household electrical appliances to finish, timer-operated contact disconnects, and promptly live wire and socket cut off the power supply automatically, and no electricity enters in the household electrical appliances; During manager's electric fault overcurrent, fuse failure has cut off electricity and has entered household electrical appliances.Integrate fuse timer and socket, thus the purpose of meeting the requirements of.

After adopting such scheme, after the household electrical appliance plug inserts this socket, set service time, the timer closing of contact, can be the same, easy to use with the use common socket, behind setting-up time, the timer contact cuts off the power supply voluntarily, has increased the sense of security that makes electrical appliance, also plays certain energy-conserving action.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

Fig. 1 is the concrete schematic diagram of implementing of the utility model.

Fig. 2 is the concrete use plate face figure that implements of the utility model.

Fig. 3 is concrete another use plate face figure that implements of the utility model.

In the schematic diagram of Fig. 1, an end of plug fuse 1 and the input of live wire join, and an end of the normally opened contact of the other end and timer 2 joins; Two of the other end of the normally opened contact of timer 2 is inserted and the slotting contact of live wire of three sockets joins; The zero line that zero line directly inserts socket 3 inserts contact; Have ground wire to insert contact on three sockets, ground wire can directly connect.

Fig. 2 is for using plate face figure, and ambroin shell 4 is made up of drain pan and face-piece; The slotting contact in two ends of plug fuse 1 is equipped with on the top of drain pan, slotting formula fuse is the two at a bar shaped ambroin, being provided with fixedly the little copper post of fuse forms, little copper post can insert the two ends of fuse 1 on the drain pan and insert in the contact fixing, and, after building face-piece, just insert, can conveniently transfer to, to change fuse.At the middle and upper part of drain pan branch, to be equipped with the Mainspring type mechanical timer 2 of two screw on drain pan, it is identical with Mainspring type mechanical timer on the washing machine, general model is DXF5, and timer has one can revolve axle, and knob 6 can revolve axle therewith and cooperate for cassette, by knob 6, but setting-up time is regulated timer 2, when being threaded to the ON position, its closing of contact, when being threaded to OFF, its contact 2 disconnects, when being threaded to other position, its contact 2 is regularly to disconnect.In the lower part of drain pan, be equipped with two and insert and the slotting contact 3 of three sockets, be screwed on drain pan.Line in Fig. 1 schematic diagram is also finished in drain pan, connects a fairlead in addition on drain pan, introduces power line and ground wire from the hole.

Should have mutually on the face-piece of plastic casing 4: there is the jack of plug fuse 1 on top; The middle and upper part branch has the axis hole that revolves of timer 2, and time scale around the axis hole and ON, OFF sign 5; The lower part has two to insert and the jack of three sockets.Face-piece, makes it to be combined into one by two screw in the middle part of the both sides on drain pan.

When using this timing socket, home electric appliance plug is inserted, if do not need regularly, then knob 6 is threaded to the ON place, promptly be not subjected to timing controlled and common the same use of socket, this moment timer 2 contacting, if need regularly, then transfer knob 6 to the required time clockwise, at this moment the closing of contact of timer 2; Socket has electricity, can use household electrical appliance, and when to the time that sets, knob 6 returns to the position of OFF, and the contact of timer 2 disconnects, and socket 3 does not have.When household electrical appliance fault overcurrent, fusible link 1 fusing plays a protective role.

The utility model also can be designed to another execution mode as shown in Figure 3, and it places left half with fuse 1 and timer 2, and two insert and three sockets 3 place right half.For similar socket, so long as adopted Fig. 1 structural principle the timing socket also be to belong to protection range of the present utility model.

Claims (3)

1, a kind of single phase poaer supply socket of being made up of plastic casing, fuse and socket is characterized in that: on the input live wire of single-phase socket, be connected in series a fuse and a timer-operated contact.

2, single phase poaer supply socket as claimed in claim 1, its spy is: timer is the mechanical timer of live contact (2), is installed between fuse (1) and the socket (3).

3, single phase poaer supply socket as claimed in claim 1 is characterized in that: integrate plug fuse (1), timer (2) and socket (3).
