Abstract
The utility model provides a protective cover structure for an outer bayonet connected electric connector, wherein the structure is simple, the operation is convenient, and the disadvantage is overcome that after a plug is insertedly connected with a socket, the prior suspension chain type protective cover cannot be conveniently fixed. In the protective cover structure, the protective cover is rotatingly arranged on the socket, an elastic element is provided between the protective cover and the socket, and with the elastic element, the inner end surface of the protective cover is pressing tightly against the front end surface of the socket under a normal state.
Description
Technical field
The utility model relates to a kind of protective cover structure that outer bayonet socket connects electric connector that is used for.
Background technology
The locking device of connector plug, socket is to realize with bayonet lock and helicla flute.Outer bayonet socket connects that the external cylindrical surface that refers to socket is equidistant to have 2～3 helicla flutes, and there are 2～3 bayonet locks in the equidistant branch of the inner cylinder face of plug.Bayonet lock reaches the purpose of locking by the end of spiral fluted angle of release entering groove during connection.
After connector plug, socket separated, the form of external chain type protective cover structure was adopted in the protection of socket usually.The bayonet lock identical with plug arranged on the inner cylinder face of protective cover, and rotation protective cover during connection, bayonet lock are also got into 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 through metallic bond, and arbitrarily swing is used in the motion occasion, is easy to come off.If protective cover is fixed, need set up vacant seat in addition, protective cover is installed on the vacant seat fixes, increase cost and inconvenient operation.
Summary of the invention
The purpose of the utility model provides the protective cover structure that a kind of simple in structure, easy to operate outer bayonet socket connects electric connector, and it overcomes existing chain type protective cover after plug and socket plug together, the shortcoming that can not fix easily.
This outer bayonet socket connects the protective cover structure of electric connector, and protective cover rotates and is arranged on the socket, when being provided with in normality between protective cover and the socket, makes the inner face of protective cover be pressed on the flexible member of socket front end face.
The beneficial effect of the utility model: flexible member makes the inner face of protective cover be pressed on socket front end face (protective cover is in closed condition) when normality.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 swung, and uses in the motion occasion, difficult drop-off yet.
Above-mentioned protective cover structure, flexible member are extension spring; Protective cover rotates through 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.Like this, no matter protective cover is to be in closed condition or open mode, extension spring all is stamped certain pulling force to protection, all makes protective cover be in stable status.
Above-mentioned protective cover structure is provided with between protective cover and socket and can keeps its inner face to be pressed on the positioner of socket front end face protective cover.Can prevent that through positioner protective cover is opened under 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 sketch map of the utility model when the protective cover closed condition.
Fig. 2 is the sketch map of the utility model 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 structure of Fig. 1, the outer bayonet socket connection electric connector shown in 2, protective cover 4 rotates (swing) through a rotating shaft 3 and is arranged on the socket 1.The inner face of protective cover 4 is provided with rubber gasket 5.Between protective cover and socket, be provided with extension spring 2, when the bottom of extension spring 2 in rotating shaft, protective cover is in closed condition, and extension spring makes the inner face (rubber gasket) of protective cover be 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 makes the inner face (rubber gasket) of protective cover be 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, reverse (downwards) rotation shank of the key locks protective cover.
In the time of need be with the opening of protective cover, rotate shank of the key, make lock ring throw off, the socket protective cover is upwards opened from latch hook, turn over the longest point of extension spring when protective cover after, protective cover location and fixing automatically under the effect of extension spring.
The utility model overcomes existing chain type protective cover after plug and socket plug together; The shortcoming that can not fix easily; The utility model advantage is simple in structure, and is 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 location and fixing automatically under the effect of extension spring.
After protective cover covers; Latch hook on the socket pins lock ring; Through controlling rotating shaft center on the socket exactly to distance and the rotating shaft center of protective cover and the distance of rubber seal face of socket seal face; Thereby make the periphery of rubber gasket all can receive identical decrement, thereby finally realize the sealing and the protection of socket.When protective cover is opened, realize the location of protective cover and fixing through extension spring and protective cover self structure.
