Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment 1: to shown in Figure 5, this plug protective jacket comprises body 1 as accompanying drawing 1, and this body 1 comprises and is used for the affixed head end 3 of socket 15 and is used to limit the tail end 5 of plug 14.Head end 3 has screw 4, and this head end 3 is affixed with socket 15 by the anti-theft screw of being located on the screw 4 16.The structure of anti-theft screw 16 can be as shown in Figure 6, the fluting of its head is " Y " shape, (perhaps other irregular moulding, as arc, T shape or the like, as long as do not match with the screwdriver of standard) screw of this structure needs special screwdriver just can turn on, so can prevent that the stranger from taking off protective jacket from socket.The structure of anti-theft screw 16 also can be as shown in Figure 7, and the fluting of its head is " one " font, and its counterclockwise therefrom the extraradial radius section of mind-set cell wall be an inclined-plane.Like this, screw can be tightened, but when screwing out in the other direction, because the effect of inclined-plane cell wall, screwdriver skids, and promptly screw can not be back-outed; Therefore in a single day this screw is tightened, and just can't open.Head end 3 internal diameters are greater than plug 14 external diameters, and tail end 5 internal diameters are less than plug 14 external diameters; Like this, the inner chamber of body 1 is the shape that can cover plug 14, and protective jacket can cover plug 14, and can not allow it come off.One side of body 1 has the wire casing 2 that is used to snap in plug cord 13.

During use, earlier plug 14 is inserted in the socket 15, realize general electrical connection, again original screw among the appliance socket screw 15-1 is back-outed, then wire casing 2 is aimed at plug cords 13 backs and be moved to plug 14, cover plug 14 after, with two anti-theft screws 16 through screw 4 screw-in socket screw 15-1.Like this, just play a protective role, plug 14 can not come off.And the special screwdriver that not is not complementary with anti-theft screw 16 just can't pull down it, prevents that children from playing or the stranger pulls up plug 14, better protecting effect.

Embodiment 2: difference from Example 1 is: head end 3 is adhered to socket 15 by adhesive 6.Like this, protective jacket promptly can't be pulled down, and prevents that effectively plug 14 from coming off.

The body 1 of protective jacket also can adopt alternate manner and socket 15 affixed.

Embodiment 3: difference from Example 1 is: body 1 is split type, comprises being used for the affixed sheath mount 1-1 of socket 15 and being connected to sheath body 1-2 on the sheath mount 1-1; Sheath mount 1-1 is provided with Plug Division 7, and sheath body 1-2 has the socket joint groove 9 that is complementary with Plug Division 7.Plug Division 7 just inserts in the socket joint groove 9, guarantees sheath mount 1-1 and the tight clamping of sheath body 1-2.Also be provided with reversed acanthoid grab 8 on the sheath mount 1-1, socket joint groove 9 madial walls have the draw-in groove 10 that is complementary with this grab 8, grab 8 is inwardly stretched and is left a determining deviation with Plug Division 7 outer walls (grab 8 also can be to overhanging and leave a determining deviation with Plug Division 7 inwalls, this moment, draw-in groove 10 was opened the lateral wall at socket joint groove 9), the space is left in both sides and Plug Division 7, like this, the space of leaving its strain of confession on every side of grab 8.When sheath mount 1-1 and sheath body 1-2 clamping, grab 8 can slip into draw-in groove 10 smoothly, plays the retaining effect.Sheath body 1-2 is connected an end at it and has the outward extending flange 11 that covers anti-theft screw 16 with sheath mount 1-1, anti-theft screw 16 can't be dismantled, and increases the protection effect.Sheath body 1-2 sidewall has observation window 12, is convenient to observe plug 14 and whether is inserted into the position, and can once more it be seated with finger by this observation window 12.

During use, earlier sheath mount 1-1 is installed on the socket 15, inserts plug 14 again, finish electrical connection.Sheath body 1-2 clamped into plug cord 13 back move to socket 15, and cooperation and sheath mount 1-1 clamping by Plug Division 7, socket joint groove 9, grab 8 embedding draw-in grooves 10 play the retaining effect simultaneously.Like this, can play protection effect.

Embodiment 4: difference from Example 3 is: draw-in groove 10 drives in the Plug Division 7, and grab 8 is located on the sheath body 1-2, and its outer hook is positioned at socket joint groove 9 and matches with draw-in groove 10.Grab 8 is to overhanging and leave a determining deviation with respect to sheath body 1-2 inwall, and both sides and sheath body 1-2 inwall leave the space, like this, leave the space for its strain around the grab 8.
