Abstract

The utility model relates to a plug. The plug comprises an insulating casing and an electric plugging piece, wherein a flexible seal ring is arranged at the front end of the insulating casing, is integrally formed at the front end of the insulating casing in a direct injection molding manner, and extends to the electric plugging piece. The plug provided by the utility model has the advantages of simple structure, water resistance and dust prevention.

Description

The waterproof and dustproof plug

Technical field

The utility model relates to a kind of plug of architecture advances.

Background technology

Existing disclosed plug, there is not the waterproof and dustproof function, and in the construction site or industrial enterprise, often the operational environment humidity, rainwater or metal dirt are arranged, the electric leakage accident takes place easily, workman's electric shock accidents also very likely occurs, and, electric leakage also causes fire easily, brings life to threaten and property loss to the people.

Summary of the invention

The purpose of this utility model is at above-mentioned existing problems, and a kind of simple in structure, waterproof and dustproof plug that the waterproof and dustproof function is arranged is provided.

The purpose of this utility model is achieved in that and comprises insulation shell and electric mortiser sheet, is provided with the flexible seal ring that extends from the direct integrated through injection molding moulding of the front end of insulation shell, toward electric mortiser sheet direction at the front end of insulation shell.

The utility model, flexible seal ring are the flexible seal ring that can overturn to the insulation shell direction at the front end of insulation shell.

The utility model, the cross section of the front end of insulation shell be shaped as circle, ellipse or square.

The utility model, the corresponding coupling of the shape of the cross section of flexible seal ring with the shape of the cross section of the front end of insulation shell.

The utility model, the number of electric mortiser sheet are two or three.

The utility model, electric mortiser sheet are to be shaped as flat type or round metal insert.

The utility model owing to adopt flexible seal ring sealed electrical plug socket or bull socket, is stopped rainwater or metal dirt enters socket, plays the waterproof and dustproof function, has advantage simple in structure, waterproof and dustproof.

Following embodiment is further described the utility model in conjunction with the accompanying drawings.

Description of drawings

Fig. 1 is an embodiment perspective view of the present utility model;

Fig. 2 is the assembling perspective view that Fig. 1 embodiment prepares to insert the bull socket;

Fig. 3 is the perspective view after Fig. 1 embodiment inserts the bull socket.

Among the figure, 1, insulation shell; 2, electric mortiser sheet; 3, the front end of insulation shell; 4, flexible seal ring; 5, bull socket; A, past electric mortiser sheet direction; B, to the insulation shell direction.

Embodiment

With reference to Fig. 1, present embodiment comprises insulation shell 1 and electric mortiser sheet 2, is provided with from the direct integrated through injection molding moulding of the front end of insulation shell, extends and can be to the flexible seal ring 4 of insulation shell direction B upset toward electric mortiser sheet direction A at the front end 3 of insulation shell; The cross section of the front end of insulation shell be shaped as circle; The cross section of flexible seal ring be shaped as circle; The electric mortiser sheet 2 of present embodiment is the flat type metal insert of three-chip type.

Use of the present utility model, with reference to Fig. 2 and Fig. 3, the electric mortiser sheet 2 of plug inserts bull socket 5, and flexible seal ring 4 is sealed in the quilt of bull socket 5 and inserts the place, plays the waterproof and dustproof function, when plug is inserted in electric plug socket, function similarly because flexible seal ring can dig, after plug is inserted in electric plug socket, flexible seal ring is replied, and naturally and understandably the quilt of electric plug socket is inserted the place and plays the waterproof and dustproof effect.
