Description
Technical field
The invention belongs to technical field of electrical components, and in particular to a kind of safety plug and socket.
Background technique
The operation of modernized society relies primarily on electric power and is used as most direct energy supply, is both needed in life and industrial production
Electrified equipment is used, electrified equipment, which generally requires, to be connected on power circuit and can run well.Electrical equipment with
It is usually attached by corresponding plug and socket between power circuit.
Plug has different standards in different countries with socket, generally includes containing ground although specification is different
Three holes of line and two kinds of type of jack of diplopore without ground wire.Firm plug is required between plug and socket, is in electrical contact, and is had
There are surface insulation and fire-retardant, waterproof performance.In household and industrial socket, in order to further strengthen to children or other groups
Safety, it is also necessary to safety screen is set at the jack of socket, safety screen can obstruct jack under normal circumstances,
It avoids that electric shock accidents occurs.Safety screen in socket has obviously effect for pre- protection against electric shock, but keeps off in socket
Plate is usually Pop-up or convertible, the connection between normal condition lower baffle plate and jack closely, if operator's power
Gas is smaller or pluggable mode is not right, is just difficult to insert or pull out plug from socket.
In addition, the baffle in conventional jack technical solution only has the function of that insulation is blocked to jack, to dust, steam
Deng not having good sealing effect, therefore this socket still remains defect in industrial application, in high temperature, high humidity, Gao Fen
In dirt, or the production environment high to vacuum degree, purity requirements, the performance of the said goods is not reached requirement still.
Summary of the invention
A kind of safety is provided the purpose of the present invention is designing a new technical solution for the problems of the prior art
Plug and socket；Jack design new type of safe anti-electric shock apparatus, and there is better waterproof and dustproof effect.
In order to achieve the above object, the present invention is achieved through the following technical solutions:
A kind of safety plug, including plug surface, pin is arranged on plug surface, and plug surface is equipped with telescopic detent convex body.
Preferably, the height of detent convex body is less than the height of pin.
Preferably, detent convex body is insulator；Insulating material has better protective performance.
A kind of socket suitable for aforementioned plug, including magazine, mounting rack and cover board, providing holes between mounting rack and cover board
Panel is arranged in plate and rotatable self-locking plate, cover board outside；Self-locking plate is the U-shaped double-deck clamping plate in section, from inside to outside includes A plate
Portion and B plate portion, orifice plate are located between the interlayer of self-locking plate；The surface setting of the self-locking plate, orifice plate and panel is slotting for being inserted into
The hole slot of foot；The hole slot of orifice plate is corresponding with the hole groove location of mounting rack；Hole slot position on the A plate portion of self-locking plate, B plate portion and panel
Correspondence is set, and is shifted to install with the hole slot of mounting rack；The detent convex body of setting and plug matches recessed in the B plate portion of self-locking plate
Slot.
Preferably, panel is circular slab, is rotatably connected between panel and cover board.
Preferably, the A plate portion of self-locking plate also sets up inwardly projecting stopple, stopple position and the hole groove location phase on orifice plate
It is corresponding, and shifted to install with the hole slot in B plate portion.
Preferably, it is connected respectively by telescopic resilience part with rotation elastic component between self-locking plate and mounting rack, panel and cover board
Between by rotation elastic component connection；Self-locking plate can stretch along the vertical direction of plane where cover board, self-locking plate and panel
It can be along Plane Rotation where cover board.
Preferably, elastic component is pipe clamp spring or wind spring.
A kind of marker being set to the plug or the receptacle face, including insulative head and panel surface are used to indicate
The alignment graticule of position and the original graticule of lid surface indicating plug rotational angle and fastening graticule.
Preferably, graticule, original graticule and fastening graticule are aligned and protrudes from corresponding body structure surface；And/or with it is corresponding
Structural material has otherness color, and/or is made of Noctilucent material；And/or contain built-in indicator light.
The present invention have it is following the utility model has the advantages that
The type safety plug and socket are internally provided with self-locking plate and orifice plate, and orifice plate is used to control the direction of motion of pin, from
Jam plate is in the original state closing the hole slot on orifice plate, so that the safety and waterproof and dustproof effect of plug are improved,
The sealing process of middle self-locking plate and panel is misplaced by way of rotation, and correspondingly, plug inserted mode is also to carry out first
Rotation is found accurately, is then inwardly seated again.The mode of this rotation dislocation and traditional convertible or Pop-up safety catch
Plate is compared, it is easier to be operated；And apply excessive active force without user, therefore the Durability of socket is also longer.
In addition, further include the stopple for blocking orifice plate in self-locking plate structure, after stopple insertion, the leakproofness of socket can be into
One step improves, and realizes more efficient waterproof and dustproof.And stopple user be inserted into plug when, due to detent convex body push against groove,
Inwardly apply active force, therefore the stopple on self-locking plate can be automatically disengaged with orifice plate, and after pulling the plug out of the socket, stopple can block up automatically again
Jack panel.
