Abstract

The utility model relates to a safety power supply plug, which comprises a plug body and an insertion sheet which are made of insulating material, wherein one end of the insertion sheet is arranged in the plug body, the other end of the insertion sheet extends out of the plug body, and a gap filling piece made of insulating material is arranged on the plug body close to the insertion sheet extending out of the plug body. Through the gap filling piece, potential safety hazards caused by dust and dirt deposited at the gap between the power supply plug and a socket are effectively avoided, and electric shock accidents caused by the insertion gap between the plug and the socket are also avoided.

Description

Safety powr supply plug
One, technical field
The utility model relates to the electronic product field, particularly relates to a kind of safety powr supply plug.
Two, background technology
At present; Attaching plug is widely applied on electric equipment, the office equipment; Common attaching plug inserted sheet external diameter is less than the jack internal diameter of supply socket, with supply socket between be connected after, leave certain gap between the inserted sheet of attaching plug and the jack of supply socket; Other analogs such as dust, dirt are deposited in the space, form short circuit easily and cause the electricity sparking.
Three, summary of the invention
In order to solve the safety problem that the space causes between attaching plug and the socket; The utility model provides a kind of safety powr supply plug; Comprise plug body, inserted sheet that insulating material constitutes; Inserted sheet one end is provided with in the plug body, and the other end stretches out outside the plug body, with stretch out the outer inserted sheet of plug body near plug body be provided with the space filling member of insulating material formation.
The said fixture that also comprises, fixture is fixed on said space filling member on the plug body.Said fixture can be a bonding piece, and the space filling member is bonded on the attaching plug body.
Said space filling member can be designed to be borehole jack shape, is sleeved on the inserted sheet outer surface, and the space filling member is designed to wedge shape away from an end of inserted sheet root, be beneficial to socket on jack peg graft.
Said space filling member can be designed to annular, and annular inner surface is provided with internal thread, and said plug body also is designed to cylindrical, scribes external screw thread on the cylindrical outer surface, and the space filling member is installed through the coupling of the external screw thread on internal thread and the plug body.Through rotation space filling member, the space filling member is flexible along the plug body longitudinal direction, and after attaching plug inserted socket, rotation space filling member formed an enclosure space with gap between attaching plug and the socket, prevents that dust, dirt from getting into.
On the annulus cross section of the space filling member of said annular sealing ring is set, the interests sealing.
Be provided with on the space filling member cylindrical anchor ring of said annular and set ahead, space filling member rotation is stirred in the aspect.
It is fast on the filling member of said space the push-and-pull card can be set, and the push-and-pull draw-in groove is set on the attaching plug body, and space filling member card is connected in the draw-in groove of attaching plug body.Realize the longitudinal extension on plug body of space filling member soon through the push-and-pull card.After attaching plug inserts supply socket, promote inserted sheet and the socket aperture contact portion formation enclosure space of space filling member with attaching plug, avoid dust, dirt to get into.
The said fast space filling member of push-and-pull card that is provided with, its with cross section that socket contacts on sealing ring is set, strengthen sealing effectiveness.
The utility model is through being provided with the space filling member, and potential safety hazard is brought in the place, space of effectively having avoided dust, dirt to be deposited between attaching plug and the socket, avoids simultaneously causing electric shock accidents because of grafting space between plug and the socket.
Four, description of drawings
Fig. 1 is the structural representation of attaching plug;
Fig. 2 is a space filling member structural representation;
Fig. 3 is the structural representation of cylindrical plug body;
Fig. 4 is an annular space filling member structural representation;
Five, embodiment
Embodiment one; Referring to Fig. 1, Fig. 2; The space filling member 3 that attaching plug comprises the plug body 1 that is made up of insulating material, inserted sheet 2, is made up of insulating material among the figure; Inserted sheet 2 one ends are directly gone in the plug body 1, and the other end of inserted sheet 2 stretches out outside the plug body 1, and inserted sheet 2 stretches out plug body 1 outer part and is used for being electrically connected with the jack of socket.Space filling member 3 is processed and inserted sheet form fit borehole jack form, and space filling member 3 is sleeved on the root that stretches out the outer inserted sheet 2 of plug body, and filling member 3 is bonded in space filling member 3 on the plug body 1 with fixture 4 towards the one side of plug body 1 direction in the space.Space filling member 3 is installed with the quantity Matching of inserted sheet 2.
Embodiment two, referring to Fig. 3, Fig. 4, and the same meaning of identical representative among label and the embodiment one among the figure; Part with identical among the embodiment one no longer repeats, and different is: plug body 1 is cylindrical; Space filling member 3 is annular, scribes external screw thread 5 on the periphery of plug body 1 near inserted sheet 2 parts, scribes internal thread 6 on the anchor ring in the space filling member 3; Be provided with on the outer ring surface of space filling member 3 and set 7 ahead; Space filling member 3 is screwed in through internal thread 6 on the external screw thread 5 of plug body 1, through rotation space filling member 3, realizes that space filling member 3 is along plug body 1 longitudinal extension.After the inserted sheet 2 of attaching plug inserts the jack of supply socket; Rotation space filling member 3 makes it protruding, and the space filling member 3 that stretches out has covered the attaching space of inserted sheet 2 and jack, makes inserted sheet 2 and jack contact portion form an enclosure space; Like this; Dust, dirt can't get into the space between inserted sheet and the jack, and the people also can't touch inserted sheet and jack, effectively avoid the generation of dust, dirt deposition and shake-up accident.
The utility model is through being provided with the space filling member, and potential safety hazard is brought in the place, space of effectively having avoided dust, dirt to be deposited between attaching plug and the socket, avoids simultaneously causing electric shock accidents because of grafting space between plug and the socket.
