Abstract
The invention provides a protective cover device which is simple in structure and convenient to operate. The protective cover device overcomes the shortcomings that the existing chain type protective cover cannot be fixed conveniently when a plug is inserted into a socket. A protective cover is rotatably arranged on a socket body, and tension springs for firmly pressing the inner end face of the protective cover on the front end face of the socket body at normal state are arranged between the protective cover and the socket body; the protective cover is rotatably arranged on the socket body through a rotating shaft; and the inner end face of the protective cover is pressed on the front end face of the socket body and is in a closed state, the inner end face of the protective cover is away from the front end face of the socket body and is in an opened state, and the tension springs are respectively arranged on two sides of the rotating shaft.
Description
Technical field
The present invention relates to a kind of for protective cover device.
Background technology
The locking device of connector plug, socket is to realize with bayonet lock and helicla flute.Outer bayonet connects that the external cylindrical surface refer to socket is equidistant 2～3 helicla flutes, and there are 2～3 bayonet locks in the equidistant branch of the inner cylinder face of plug.Bayonet lock enters the end of groove by the spiral fluted angle of release during connection, reaches the purpose of locking.
After connector plug, socket separated, the form of external chain type protective cover device was adopted in the protection of socket usually.The bayonet lock identical with plug arranged on the inner cylinder face of protective cover, rotation protective cover during connection, bayonet lock is also entered the end of groove by the spiral fluted angle of release, reach the purpose of protection.The shortcoming of this structure is: when plug and socket plugged together, protective cover was to pull on socket by metallic bond, arbitrarily swung, and used in the motion occasion, was easy to come off.If protective cover is fixed, need to set up in addition vacant seat, protective cover is installed on the vacant seat fixes, increase cost and inconvenient operation.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate protective cover device, it overcomes existing chain type protective cover after plug and socket plug together, the shortcoming that can not fix easily.
This protective cover device, protective cover rotate and to be arranged on the socket, when being provided with in normality between protective cover and the socket so that the inner face of protective cover is pressed on the extension spring of socket front end face; Protective cover rotates by a rotating shaft and is arranged on the socket; The inner face of protective cover is pressed on the socket front end face and when being in closed condition, and the inner face of protective cover is when being in open mode away from the socket front end face, and extension spring is respectively in the both sides of rotating shaft.
Beneficial effect of the present invention: flexible member when normality so that the inner face of protective cover is pressed on socket front end face (protective cover is in closed condition).When needs are opened protective cover, only need to rotate (swing) protective cover and get final product.Because protective cover is to rotate to be arranged on the socket, protective cover can arbitrarily not swing, and uses in the motion occasion, difficult drop-off yet.No matter protective cover is to be in closed condition or open mode, extension spring all is stamped certain pulling force to protection, all so that protective cover is in stable state.
Above-mentioned protective cover device is provided with between protective cover and socket and protective cover can be kept its inner face be pressed on the positioner of socket front end face.Can prevent that by positioner protective cover is opened in unexpected situation.Positioner has varied, and a kind of simple positioner comprises the latch hook that is arranged on the socket, is arranged on shank of the key and lock ring on the protective cover.
Description of drawings
Fig. 1 is the schematic diagram of the present invention when the protective cover closed condition.
Fig. 2 is the schematic diagram of the present invention when the protective cover open mode.
Among the figure, 1: socket; 2: extension spring; 3: rotation axis; 4: protective cover; 5: rubber gasket; 6: latch hook; 7: lock ring; 8: shank of the key.
Embodiment
Referring to the protective cover device shown in Fig. 1,2, protective cover 4 rotates (swing) by a rotating shaft 3 and is arranged on the socket 1.The inner face of protective cover 4 is provided with rubber gasket 5.Be provided with extension spring 2 between protective cover and socket, when the bottom of extension spring 2 in rotating shaft, protective cover is in closed condition, and extension spring is so that the inner face of protective cover (rubber gasket) is pressed on the socket front end face; When the top of extension spring 2 in rotating shaft, protective cover is in open mode, and extension spring is so that the inner face of protective cover (rubber gasket) is pressed on the socket front end face away from the socket front end face.
Positioner comprises the latch hook 6 that is arranged on the socket, is arranged on shank of the key 8 and lock ring 7 on the protective cover.Rotate protective cover after cover (closing) position, rotate shank of the key, make lock ring buckle into latch hook after, oppositely (downwards) rotation shank of the key locks protective cover.
In the time of need to be with the opening of protective cover, rotate shank of the key, so that lock ring is thrown off from latch hook, the socket protective cover upwards opened, turn over the longest point of extension spring when protective cover after, protective cover automatic location and fixing under the effect of extension spring.
The present invention overcomes existing chain type protective cover after plug and socket plug together, the shortcoming that can not fix easily, and advantage of the present invention is simple in structure, easy to operate, and when plug insertion socket, self can locate the socket protective cover and fix, and need not to set up miscellaneous part and fixes the socket protective cover.
Covering of protective cover: should rotate protective cover to covering the position, rotate shank of the key, make lock ring buckle into latch hook after, the backward rotation shank of the key locks protective cover.Opening of protective cover: rotate shank of the key, throw off lock ring after, the socket protective cover is upwards opened, turn over the longest point of extension spring when protective cover after, protective cover automatic location and fixing under the effect of extension spring.
After protective cover covers, latch hook on the socket pins lock ring, by controlling exactly spindle central on the socket to distance and the spindle central of protective cover and the distance of rubber seal face of socket seal face, thereby make the periphery of rubber gasket all can be subject to identical decrement, thereby finally realize sealing and the protection of socket.When protective cover is opened, realize the location of protective cover and fixing by extension spring and protective cover self structure.
