Description
Technical field
The utility model relates to a kind of plug, especially relates to a kind of ejection type band cover protection plug.
Background technology
Existing electric equipment attaching plug, its plug slice is directly exposed to the outside usually, improper use, user's finger is the plug slice of contact exposure very easily, is easy to cause electric shock accidents.Though occurred some technology in succession; as passing through supplementary protection cover outside inserted sheet; and spring is set offsets with it; after but inserted sheet inserts socket,, cause plug to come off easily because the elastic force of spring acts on socket surface by sleeve; even plug ejected; bring inconvenience, there is potential safety hazard in infringement electrical equipment.
Summary of the invention
The purpose of this utility model is: avoid above-mentioned defective, improve the safe handling structure of plug, a kind of ejection type band cover protection plug is provided, in the insertion process, because the protective effect of slip protective sleeve can be avoided finger contact inserted sheet.After the insertion, the projection of the continuous push rod of its slip protective sleeve can be interlocked with the square location hole on the plug sidewalls, can make plug contact firmly difficult drop-off, ejection with socket.
The technical solution of the utility model is: comprise body; inserted sheet; also comprise the slip protective sleeve that inserted sheet centers on outward; be provided with stage clip between the holder of protective sleeve and inserted sheet; described stage clip is located on the inserted sheet; described slip protective sleeve is located at the inserting-plate hole on the body by inserted sheet passed through; described slip protective sleeve is positioned at the body inner end and is interconnected to constitute integral body near plug axis one side; described slip protective sleeve is positioned at the body inner end and is provided with projection near sidewall one side; this projection has elastic push rod near sidewall one side direction; this push rod lower end is provided with the cuboid projection near sidewall one side; the outer wall of described body has square location hole, and described holder is provided with baffle plate.
The beneficial effects of the utility model are: simple in structure, easy to use, can avoid because of holding the incorrect electric shock accidents that causes of mode, and plug contacts with socket firmly, and difficult drop-off, ejection, safe and reliable.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: comprise body (1), inserted sheet (2); comprise that also inserted sheet (2) is arranged with slip protective sleeve (3); this slip protective sleeve (3) hollow; through hole is set; be provided with stage clip (5) between the holder (4) of slip protective sleeve (3) and inserted sheet (2), this stage clip (5) is set on the inserted sheet (2), described slip protective sleeve (3) is located at inserting-plate hole (6) on the body (1) by what inserted sheet (2) passed through.Insert conveniently in order to adorn, inserted sheet (2) should have the termination of exposing.For anti-sliding stop protective sleeve (3) is ejected body (1), the end that described two slip protective sleeves (3), (7) are positioned at body (1) is interconnected to constitute integral body near plug axis one side.For realizing fastening; sidewall (8) one sides that described slip protective sleeve (3) is positioned at the close plug in end of body (1) are provided with projection (9); this projection (9) has flexible push rod (10) near sidewall (8) one side direction; described push rod (10) lower end is provided with cuboid projection (11) near sidewall (8) one sides; described body (1) is the structure of falling the trapezoidal solids; described sidewall (8) has square location hole (12); plug is in inserting the socket process; should be able to make elastic push rod (10) be subjected to the contention effect of sidewall (8); described projection (11) is under the elastic reaction of push rod (10); buckling into location hole (12) also partly stretches in outside the body (1); correct concordant on the described slip protective sleeve (3) with body (1) outer surface; the protective sleeve (3) that slides this moment is fixed by the projection (11) and the fastening effect of location hole (12); can prevent that plug from coming off; eject; and during insertion; since slip protective sleeve (3) stage clip (5) effect down with the socket surface tight fit, can avoid finger to contact inserted sheet (2).After plug is extracted, touch the projection (11) that is positioned at outside the body (1) to the inside, because the effect of stage clip (5), described slip protective sleeve (3) launches automatically and resets.In addition; described holder (4) is provided with baffle plate (13); when this baffle plate (13) should be able to buckle into location hole (12) in projection (11) and slip protective sleeve (3) end that is positioned at body (1) closely cooperates; can guarantee that inserted sheet (2) is after inserting socket; inserted sheet (2) and stage clip (5) are isolated fully with the external world, guarantee safety.
