Abstract

The utility model relates to a plug, comprising a body and pins fixed to the body; a telescopic sleeve body with elasticity fixed to the body is sheathed on the pins. The sleeve body is made of plastic or rubber which is insulating material; when the pins of the plug are inserted into the jacks of the socket, the sleeve body is baffled out of the jacks of the socket, so even with mistake operation or children play, hands do not directly contact with the pins but the sleeve body; the insulating sleeve body is used safely without electric shock danger.

Description

A kind of plug

Technical field

The utility model relates to a kind of plug.

Background technology

Existing plug comprises body and the pin that is fixed on the body, the plug that has has two pins, the plug that has has three pins, and these pins are metallic conduction sheet or metallic conduction post, during use the pin of plug is inserted in the jack of socket with energized.Under the situation of normal bimanualness, the people can not get an electric shock.If but in operating process, hand then gets an electric shock before the pin of plug is pulled out receptacle sockets and touch the pin of plug easily.The child who particularly has sometimes likes playing with plug, does not insert fully under the loosening situation of the jack of socket or plug in the trick of plug, more holds the liability electric shock accidents.This creator actively makes great efforts research at this situation, through research and development with great concentration, invents out the utility model of true tool practical effect and industrial utilization finally.

Summary of the invention

The purpose of this utility model provides a kind of plug safe in utilization.

For achieving the above object, the utility model is taked following design: a kind of plug, comprise body and the pin that is fixed on the body, and it is characterized in that: be arranged with the scalable body of the elasticity that is fixed on the described body on the described pin.

Described cover surface is a smooth surface.

Described cover surface axially is corrugated.

Described body quantity equates with described pin quantity, is arranged with a described body on each described pin.

Described body quantity is one, and it is set in the periphery of all pins.

The utility model has the advantages that: a kind of plug of the utility model, comprise body and the pin that is fixed on the body, be arranged with the scalable body of the elasticity that is fixed on the body on the pin.Insulating material such as cover body and function plastics or rubber are made, when plug base pin is inserted receptacle sockets, body is blocked in outside the receptacle sockets, so both made when misoperation or child play with, hand can directly not contact pin yet, be arranged with the insulating case body outward and only can contact pin, Danger Electric shock risk can not take place, use comparison safety.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of plug of the utility model comprises body 1 and the pin 2 that is fixed on the body 1, is arranged with the scalable body 3 of the elasticity that is fixed on the body 1 on the pin 2.Insulating material such as body 3 usefulness plastics or rubber are made, when plug base pin 2 is inserted receptacle sockets, body 3 is blocked in outside the receptacle sockets, so both made when misoperation or child play with, hand can directly not contact pin yet, be arranged with insulating case body 3 outward and only can contact pin, Danger Electric shock risk can not take place, use comparison safety.

Body 3 surfaces are smooth surface (as shown in Figure 1).

Body 3 surfaces also can be axially to be corrugated (as shown in Figure 2).

Body 3 quantity equate with pin 2 quantity, are arranged with a body 3 (as shown in Figure 1 and Figure 2) on each pin 2.

Body 3 quantity are one, and it is set in the periphery (as shown in Figure 3, Figure 4) of all pins 2.

The above;, be not that attempt is done any pro forma restriction to the utility model according to this, only so every under the creation spirit of the utility model for being used for explaining the preferred embodiment of the utility model; any modification or the change done all must belong to the scope that the utility model is intended to protection.

Claims

1, a kind of plug comprises body and the pin that is fixed on the body, it is characterized in that: be arranged with the scalable body of the elasticity that is fixed on the described body on the described pin.

2, plug according to claim 1 is characterized in that: described cover surface is a smooth surface.

3, plug according to claim 1 is characterized in that: described cover surface axially is corrugated.

4, according to claim 1 or 2 or 3 described plugs, it is characterized in that: described body quantity equates with described pin quantity, is arranged with a described body on each described pin.
