Abstract

The utility model discloses an accessory of a daily electrical appliance, and relates to a plug pole piece protection device, wherein an edge of each pole piece of a plug is provided with insulating block pieces, one end of the insulating block piece is connected by using an elastic element in the plug, and the other end of the insulating block piece is extended out in parallel with the pole piece. The plug pole piece protection device of the utility model can prevent electric leakage of the pole pieces when the plug is inserted into a socket, thereby increasing a security coefficient of the plug.

Description

Plug pole piece protective device

Technical field

The utility model relates to a kind of annex of household appliance, is specifically related to a kind of plug pole piece protective device.

Background technology

Usually the pole piece on the plug all exposes, and when plug pole piece socket is switched on, easily causes leaky, especially old man, child is because strength is little, but pole piece is easy to cause security incident when having switched on and not pressed down fully in the jack of socket.

The utility model content

The utility model purpose: for the problems referred to above, the purpose of this utility model provides a kind of plug pole piece protective device.

Technical scheme: a kind of plug pole piece protective device, at the edge of each pole piece of plug the insulation catch is housed, described insulation catch one end connects with elastomeric element in plug, and the other end is parallel with pole piece to be stretched out.

Described insulation catch be furnished with following three kinds of modes.

(1) described catch is pole piece outside and both sides inwardly.

(2) described catch is that pole piece is towards one side of outside.

(3) described catch is around pole piece.

The above catch nature top is than the short 0.2 ~ 0.5mm in the top of pole piece.

Beneficial effect: compared with prior art, the utility model has the advantages that and in plug insertion socket, to prevent the pole piece electric leakage, increase the coefficient of safety of plug.

Fig. 2 is Figure 1A-A face cutaway view Amplified image.

Fig. 3 is the cutaway view Amplified image of the second execution mode.

Fig. 4 is the cutaway view Amplified image of the third execution mode.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.

A kind of plug pole piece protective device as shown in Figure 1; insulation catch 3 is housed at the edge of plug 1 each pole piece 2; described insulation catch 3 one ends are interior with the elastomeric element connection at plug 1, and the other end and pole piece 2 parallel stretching out are when using; the jack of pole piece 2 alignment sockets is inserted; catch 3 is namely blocked by the other part of receptacle sockets, thereby catch 3 is pushed the inside of plug 1, and catch is because the effect of elastic force; all the time contact with socket, thereby guarantee that pole piece can not leak outside cruelly.

Described insulation catch be furnished with following three kinds of modes:

As shown in Figure 2, described catch 3 is pole piece 2 outsides and both sides inwardly.

As shown in Figure 3, described catch 3 is that pole piece 2 is towards one side of outside.

As shown in Figure 4, described catch 3 is around pole piece 2.

The above catch 3 nature top is than the short 0.2 ~ 0.5mm in the top of pole piece 2, makes things convenient for the accurately jack on the alignment socket of pole piece 2.
