Abstract

The utility model discloses a safe plug, including a plug body, a wire and an insertion piece. The plug body is provided with a protective cover wrapping the insertion piece; the protective cover is provided with a through hole corresponding to the insertion piece; the plug body is also provided with an annular groove for accommodating the protective cover; simultaneously, the middle position of the plug body is provided with a spring fixed groove; a compression spring is provided in the spring fixed groove; one end of the compression spring is fixedly arranged at the groove bottom of the spring fixed groove, and the other end is fixedly arranged at the lower surface of the spring fixed groove; and when the safe plug is in use, whether when the safe plug is inserted in or pulled out from a supply socket, the insertion piece is never exposed to the exterior, thereby the safety of an operator is guaranteed.

Description

Safety plug
Technical field
The utility model relates to the plug technical field, relates in particular to a kind of safety plug.
Background technology
Existing electric equipment and household electrical appliance all have attaching plug and are used to insert the supply socket energized; But this common problem of plug ubiquity: because the inserted sheet of attaching plug need have certain length; Help guaranteeing to realize reasonably contact with the intermediate plate of supply socket; So inserting or extracting in the process of supply socket; The charged and complete exposed time of inserted sheet that of short duration attaching plug is just arranged, this time has brought great hidden danger for operator's safety.
The utility model content
The utility model technical problem to be solved is: a kind of safety plug is provided, and this plug is when inserting or extracting supply socket, and inserted sheet can not expose outside, for operator's safety provides guarantee.
For solving the problems of the technologies described above; The technical scheme of the utility model is: safety plug, comprise header body, electric wire and inserted sheet, and said header body is provided with the protective cover that can wrap up said inserted sheet; Said protective cover is provided with and the corresponding through hole of said inserted sheet; Have the cannelure that can hold said protective cover on the said header body, the centre position of said header body has the spring holddown groove, is provided with the compression spring in the said spring holddown groove; One end of said compression spring is fixed in the bottom land of said spring holddown groove, and the other end is fixed in the lower surface of said protective cover.
As a preferred implementation, said protective cover all adopts plastic member with the compression spring.
After having adopted technique scheme, the beneficial effect of the utility model is: owing on header body, be provided with the protective cover that is used to wrap up inserted sheet, and also this protective cover is arranged in the cannelure of header body; In the spring holddown groove, be provided with the compression spring that an end is fixed in the protective cover lower surface again; Then when this safety plug was inserted socket, said protective cover can move in cannelure under the effect of socket, compressed the spring pressurized simultaneously and shortened; Contact with header body until said protective cover lower surface; This moment, header body can not upspring from supply socket owing to the clamping action of supply socket inner clamp piece to inserted sheet, and in whole process; Said inserted sheet is not exposed to the outside, has guaranteed operator's safety; When the operator with this safety plug when supply socket is extracted; Because the effect of compression spring; Said protective cover can rely in the supply socket always, and until inserted sheet is separated with supply socket fully, protective cover has avoided inserted sheet to be exposed to the outside equally in this process.
Because what protective cover in this safety plug and compression spring all adopted is plastic member, not only can further increase its security performance, and cost is lower, practices thrift cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the schematic top plan view among Fig. 1;
Among the figure: 1. electric wire; 2. header body; 3. inserted sheet; 4. cannelure; 5. spring holddown groove; 6. protective cover; 7. compression spring.
Embodiment
Shown in Fig. 1 and Fig. 2 are common, be a kind of structural representation and its schematic top plan view of safety plug, this safety plug comprises electric wire 1, header body 2 and inserted sheet 3; On said header body 2, have a cannelure 4; Be movably equipped with the protective cover 6 that can wrap up said inserted sheet 3 in the said cannelure 4, said protective cover 6 is provided with and said inserted sheet 3 corresponding through holes, like this; Said inserted sheet 3 can stretch out from through hole, can guarantee that said in use inserted sheet 3 is not exposed outside simultaneously.
Have spring holddown groove 5 in the centre position of said header body 2, be provided with a compression spring 7 in the said spring holddown groove 5, an end of said compression spring 7 is fixed in the bottom land of said spring holddown groove 5, and the other end is fixed in the lower surface of said protective cover 4.
The operation principle of this safety plug is:
When the operator is inserted into supply socket; Said protective cover 4 can move in said cannelure 4 under the effect of supply socket; Compress said compression spring 7 simultaneously, when this safety plug inserted supply socket fully, the lower surface of said protective cover 4 contacted with said header body 2; The intermediate plate of supply socket simultaneously can overcome the elastic force of said compression spring 7 to the clamping force of said inserted sheet 3, avoids this safety plug to upspring from supply socket.
When the operator with it when supply socket is extracted, said protective cover 4 can rely in the supply socket under the elastic force effect of compression spring 7 always, until inserted sheet 3 is separated with supply socket fully.
In above two processes, no matter be that safety plug is inserted supply socket or it is extracted supply socket, said protective cover 4 is contacted with supply socket all the time, promptly said inserted sheet 3 never is exposed to the outside, for the operator provides safety guarantee.
In order further to increase the safety in utilization of this safety plug; Reduce the manufacturing cost of this safety plug simultaneously, the above-mentioned protective cover that is mentioned to 4 all adopts plastic member with compression spring 7, in addition; This safety plug is not only applicable to two-pin plug illustrated in figures 1 and 2; Be equally applicable to three-pin plug, its principle and structure similar repeat no more at this.
The utility model is not limited to above-mentioned embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection range of the utility model.
