Abstract

A socket and plug preventing the electrical shock is provided. A projection is provided on the position one fifth of a pin; a movable contact with electricity is provided on the socket corresponding to the projection; the flex of the contact is controlled by a slide block positioned on the lower part; the displacement of the slide block is determined by the pin; the current taken from the socket should be arranged with pins matching the socket and having certain shapes and conductors of other shapes can not take current, therefore, the utility model has good safe performance.

Description

A kind of anti-electric shock socket plug

Affiliated technical field

The utility model relates to socket, the plug of power supply.

Background technology

The power connection points of household electrical appliance, no matter be movably temporarily, still fixing socket, plug, it generally is the plastic cement of casing insulation, inside is made of several groups of copper sheets, and this socket, plug are safe under routine operation, if disclose the hole as the not too sensible child that has who reports in newspaper, the TV with the conductor reeve of iron nail, iron wire and so on, the accident that just has the electric shock causing death takes place, thereby such socket, plug exist potential safety hazard.

Summary of the invention

The purpose of this utility model provides a kind of safe and reliable supply socket, plug.

For achieving the above object, there is a protrusion at 1/5th places to the pin of the utility model plug in the end, and protuberate 0.3-0.6cm has the live contact of an activity with the corresponding socket of this protrusion place, this contact flexible by the sliding shoe control that places the bottom;

Sliding shoe is corresponding with thin place, pin end.The contractility of sliding shoe and contact has the activity template transmission of fulcrum again by the center, its power that resets is provided by the spring of the other end, thereby the energising of pin whether, by the shape decision of pin.

When socket did not use at ordinary times, sliding shoe was owing to spring force, and its outer end is exposed at outside the collets, and live contact is contracted within the collets.Under this state, if accidentally inject things such as thin wire, iron nail, even if the contact of contracting in the sliding shoe is overhanging, and iron wire, iron nail do not have protrusion, still touch less than the contact, can not meet accident.If inject the bonding jumper with the same thickness of pin protrusion, the ledge that then can be insulated piece blocks, and can not make the sliding shoe displacement, and bonding jumper is not charged, thereby this socket, plug have more fail safe.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model peacetime state schematic diagram.

Fig. 2 is the utility model working state schematic representation.

Embodiment

Shown in Figure 1, there are collets 9 socket 1 inside, and it is stepped that the collets both sides become, and secondary enlarges downwards.At ordinary times not under the user mode, movable block 4 is under spring 6 elastic force effects, and the outer end is exposed at outside the collets, being connected of an inner end activity by hinge 7 and activity template 5; There is fixing fulcrum 8 at the center of activity template 5, and the other end is connected by hinge and live contact 3 activities; Contact 3 is contracted within the collets under the acting in conjunction of activity template 5, spring 6, sliding shoe 4.

Shown in Figure 2, injected the pin 2 on the plug, thin position, pin 2 lower ends contacts with sliding shoe 4, and compression sliding shoe 4 makes it to compress spring 6 and is subjected to displacement; Move in the sliding shoe 4, activity template 5 is rotated around fulcrum 8, thereby it is overhanging to promote live contact 3, contacts with the protrusion of pin 2 corresponding positions, plug just has electric current output.

Under Fig. 1 unused state, if inject thin metallic object, to contract though can make in the sliding shoe 3, contact 3 is overhanging, because of metallic object does not have protrusion, and can be not charged.If what inject is thick metallic object, then can be insulated piece and block, can not make in the sliding shoe 4 and contract, contact 3 is within collets, and metallic object can be not charged yet.

But this socket is operate as normal just under specific plug, special pin shape only, thereby very high fail safe is arranged.

Claims

1. anti-electric shock socket plug, it is characterized in that: there are a protrusion, protuberate 0.3-0.6cm in 1/5th places to the pin of plug in the lower end.

2. anti-electric shock socket plug, it is characterized in that: corresponding part with the protrusion of pin has the live contact of an activity in socket: thin place is corresponding local with the pin end, and the sliding shoe of an activity is arranged; Have activity template two ends to connect movable connecting terminal and sliding shoe with strand respectively, there is mobilizable fulcrum at the activity template center; The power that resets of sliding shoe is provided by a spring.

3. anti-electric shock socket plug according to claim 2 is characterized in that: stepped collets are arranged in the socket.
