Abstract

The utility model relates to a multipurpose control switch which is connected with a power on coil circuit and a control circuit of a current controller 2 of a fire wire via using a magnetic coil 3 for generating a magnetic field to drive a moving iron core 4 and a movable contact 8 of the movable iron core close to a static contact 9 of the magnetic coil 3. Once the over current phenomenon is generated, the current controller generates action to disconnect the control circuit, the movable iron core 4 returns back, the movable contact 8 and the static contact 9 are disconnected, and fire hazard caused by the electric firing of the over current is effectively prevented.

Description

Use control switch more

Technical field

The utility model relates to a kind of control switch of using more.

Background technology

People have used protective device in the place of some high pressure, big load now; do not arouse attention and add, but be exactly that the accidents such as fire that cause of these carelessness have caused great loss in the place of family, public place of entertainment, hotel and multiple single-phase little load.

Summary of the invention

The purpose of this utility model provides a kind of circuit that can prevent effectively and bumps fire, short circuit, aging and cause overcurrent, and the control switch of using of electricity burning causing fire takes place more.

The purpose of this utility model is achieved in that in the inside of a box body two " mountain " shape iron cores, and two iron core openings stand on an one in the box relatively; The top at the two ends of following static iron core opening has a short-circuited conducting sleeve to embed wherein respectively, and two sides respectively have iron plate to be fixed thereon and to extend to the two ends of top moving iron core, and the top of iron plate respectively has a sulculus; The two ends of moving iron core opening respectively have a pin to be fixed thereon, pin is upper and lower moving in the sulculus of iron plate, in " mountain " shape mouth of moving iron core two springs are arranged, respectively there is the contiguous block of a moving contact two sides, middle part of iron core, and it is connected with moving contact by spring; There is a magnetic coil centre of two iron cores, on the insulation crust of magnetic coil, the both sides of iron core have two fixed contacts respectively; Another part in box is a current controller, and it is connected with the switch of box body outside.

Connection mode of the present utility model is: zero line inserts a end of a pair of fixed contact, enter magnetic coil from a end, insert a end of the normally closed interlock of switch again from magnetic coil, go into a end of the normally open contact of switch again from the normally closed interlock b termination of switch, go into a end of the normally closed interlock of current controller again from a termination of the normally open contact of switch, the b termination single line from the current controller normally closed interlock enters another b end to fixed contact again; Live wire directly inserts b end and another a end to fixed contact of the normally open contact of switch; Active line enters the coil of current controller from the b end of live wire fixed contact, receives on the outgoing line device again, and another root active line is directly received on the outgoing line device from the b end of zero line fixed contact.

Owing to adopted structure of the present utility model, using at that time, as long as surpass 10～20 milliamperes of electric currents during electric operation, switch will be at once the electricity in the line disconnection automatically, thereby reached the effect of protection electrical equipment.

Fig. 2 is a conspectus of the present utility model.

Embodiment

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

1, box body 2, current controller 3, magnetic coil 4, moving iron core 5, contiguous block 6, spring

7, spring 8, moving contact 9, fixed contact 10, static iron core 11, iron plate 12, short-circuited conducting sleeve

13, pin 14, sulculus 15, switch

As shown in Figure 1, the utility model is to have two " mountain "

shape iron cores

4 and 10, two iron core openings to stand in the box one one relatively in the inside of a box body 1; The top at the two ends of following static iron core 10 openings has a short-circuited conducting sleeve 12 to embed wherein respectively, and two sides respectively have an iron plate 11 to be fixed thereon and to extend to the two ends of top moving iron core 4, and the top of iron plate 11 respectively has a sulculus 14; The two ends of moving iron core 4 openings respectively have a pin 13 to be fixed thereon, pin 13 is upper and lower moving in the sulculus 14 of iron plate 11, in " mountain " shape mouth of moving iron core 4 two springs 6 are arranged, respectively there is the contiguous block 5 of a moving contact 8 both sides, middle part of iron core 4, and it is connected with moving contact 8 by spring 7; There is a magnetic coil 3 centre of two iron cores, on the insulation crust of magnetic coil 3, the both sides of iron core have two fixed contacts 9 respectively; Another part patent No. in box is the current controller 2 of ZL 01257188.1, and it is connected with the switch 15 of box body 1 outside.

As shown in Figure 2, connection mode of the present utility model is a end that zero line inserts a pair of fixed contact 9, enter magnetic coil 3 from a end, insert a end of the normally closed interlock of switch 15 again from magnetic coil 3, go into a end of the normally open contact of switch again from the normally closed interlock b termination of switch, go into a end of the normally closed interlock of current controller 2 again from a termination of the normally open contact of switch, the b termination single line from the current controller normally closed interlock enters another b end to fixed contact 9 again; Live wire directly inserts b end and another a end to fixed contact of the normally open contact of switch; Active line enters the coil of current controller from the b end of live wire fixed contact, receives on the outgoing line device again, and another root active line is directly received on the outgoing line device from the b end of zero line fixed contact.

After the energising, started magneticaction, moving contact 8 and fixed contact 9 closures, the hot-wire coil circuit and the control circuit of making current controller 2 simultaneously.

During use, press normal open switch, magnetic coil 3 produces magnetic field and drives moving iron core 4, and moving contact 8 on the moving iron core and fixed contact 9 closures on the magnetic coil 3 have been connected the hot-wire coil and the normally closed control contact of current controller 2 on the live wire simultaneously; In case generation over-current phenomenon avoidance, current controller 2 work produce the controlling magnetic field greater than current controller, movable core in the current controller backs down normally closed hoe wherein, the control circuit outage, moving iron core 4 returns, fixed contact 9 on moving contact 8 and the coil disconnects, and has so just prevented effectively that overcurrent from the electricity fire that causes etc. that burns taking place.
