Abstract
The utility model relates to an attaching plug. In order to solve a problem that electric sparks generated by friction in inserting a plug is easy to bring dangers to people, the utility model provides an electric spark resisting plug. A cylindrical elastic insulating protection cover capable of covering a plug body is sleeved on the external side of an insulator. The inner diameter of the elastic insulating protection cover is larger than the diameter of the insulator. Before the plug body contacts with a metal sheet in a socket, the elastic insulating protection cover contacts with the socket, thereby blocking sparks generated by the friction of the plug body and the metal sheet of the socket inside the elastic insulating protection cover and avoiding personal risks. Therefore, compared with a common attaching plug, the electric spark resisting plug provided by the utility model is safer.
Description
Technical field
The utility model relates to a kind of attaching plug, relates in particular to a kind of anti-electric spark plug.
Background technology
Having many uses of attaching plug is general, and big and small industry all possibly need attaching plug visible, the purposes of attaching plug and each corner that spreads all over our life.Though plug and socket all has fixing specification, because manufacturer or batch difference, tending to occur plug and socket is not the problem of mating very much.Therefore, with plug insertion socket the time, will produce electric spark because of the friction between the plug and socket, very dangerous.
Summary of the invention
When inserting plug in order to solve, fricative electric spark brings dangerous problem to the people easily, and the utility model provides a kind of anti-electric spark plug.
The technical scheme of the utility model:
A kind of anti-electric spark plug comprises by the insulator and the slotting body of drawing from insulator, and its special feature is, also comprises the elastic insulated protective cover of tubular that is enclosed within the insulator outside and can covers slotting body; The internal diameter of elastic insulated protective cover is greater than the corresponding size of insulator.The material of this elastic insulated protective cover is an elastic rubber material.Elastic insulated protective cover is the tubular that a two does not all have sealing, and the shape and the insulator of nozzle adapt, and the length of slotting body is a bit larger tham or is slightly smaller than to its length.Can be to be fixedly connected between insulator and the elastic insulated protective cover, also can be to removably connect.The wall thickness of elastic insulated protective cover confirms specifically that according to selected material that should try one's best is thin to avoid elastic insulated protective cover when compressing, to produce accumulation.
The anti-electric spark plug that the utility model provides, preferred, described elastic insulated protective cover is the tubular of internal diameter gradual change, and its minimum diameter is the size with insulator joint end; Its surface design is a helical form.The compression of convenient elastic insulated protective cover.
The anti-electric spark plug that the utility model provides, preferred, the length that the length of the outstanding insulator of described elastic insulated protective cover equals to insert body.
The beneficial effect of the utility model:
Before inserting body and sheet metal in the socket contacts, elastic insulated protective cover contacts with socket; Thereby slotting body and the fricative spark of socket sheet metal are blocked in the elastic insulated protective cover, can produce the Personal Risk.Therefore, insert body with common power and compare, the anti-electric spark plug that the utility model provides is safer.
Description of drawings
Fig. 1 is the structural representation of anti-electric spark plug;
Among the figure, 1. insulator is 2. inserted body, 3. elastic insulated protective cover.
Embodiment
Below in conjunction with Fig. 1 the utility model is specified.
The anti-electric spark plug that the utility model provides mainly comprises the jack body of being made up of insulator 1 and slotting body 2, and elastic insulated protective cover 3.Insulator 1 among Fig. 1 is the cylinder of Diameter Gradual Change, and therefore, elastic insulated protective cover 3 is cylindrical shape and is the drum of internal diameter gradual change.Its minimum diameter is slightly larger than the maximum gauge of insulator 1, and the minimum diameter of promptly elastic insulated protective cover 3 is slightly larger than the diameter in insulator 1 cross section contacted with it.The tube length of elastic insulated protective cover 3 equals to insert the length of body 2 outstanding insulators 1.The surface of elastic insulated protective cover 3 is shape in the shape of a spiral, adopts transparent elastic rubber material.
When using, elastic insulated protective cover 3 contacts with receptacle face earlier, then, inserts body 2 and contacts with the sheet metal of socket; Along with the increase of dynamics, elastic insulated protective cover 3 is compressed or upwards digs.When slotting body 2 contacted with the sheet metal of socket fully, elastic insulated protective cover 3 was compressed to very thin one deck, does not hinder the normal use of header body; Perhaps elastic insulated protective cover 3 is dug fully, and insulator 1 contacts with receptacle face, does not influence the normal use of header body equally.
Claims (3)
1. an anti-electric spark plug comprises by insulator with from the slotting body that insulator is drawn, and it is characterized in that, also comprises being enclosed within the insulator outside and covering the elastic insulated protective cover of tubular of inserting body; The internal diameter of elastic insulated protective cover is greater than the corresponding size of insulator.
2. anti-electric spark plug according to claim 1 is characterized in that described elastic insulated protective cover is the tubular of internal diameter gradual change, and its minimum diameter is the size with insulator joint end; Its surface design is a helical form.
3. anti-electric spark plug according to claim 1 is characterized in that, the length that the length of the outstanding insulator of described elastic insulated protective cover equals to insert body.
