Description
Technical field
The utility model belongs to electrical equipment distribution field, is specifically related to a kind of Anti-disconnecting plug socket, the phenomenon that gets loose that this plugs and sockets can effectively avoid plug and socket in operation, to take place owing to improper action.
Background technology
As everyone knows; General household electrical appliance and electric tool all need could be worked through connecting power supply; And the method that connects power supply at present is exactly that the attaching plug that electrical equipment and instrument carry is inserted in the corresponding supply socket, thereby electrical equipment and electric tool energising are used.
In practical application, find; Because traditional plug and socket is to be provided with elastic contact blade in socket inside; Behind the plug insertion socket, said elastic contact blade is pressed on the elastic contact blade under self elastic force effect; Thereby realize being electrically connected, confining force between the two and steadiness are to lean on the elastic force of elastic contact blade to guarantee; But as common washing machine is shaking phenomenon to occur in drying; When using electric drill or other similar instruments can phenomenon or the like appear pulling because of the construction distance changes; In this case, the plug of power line and supply socket have taken place loosening and have produced loose contact and heating phenomenon, also can therefore make when serious to occur sparking between plug and the socket; There is potential potential safety hazard in the direct initiation fire of meeting when serious; Nowadays also occurred some on the market in succession and had the plugs and sockets of anti-loose function, but its structure is still unreasonable, the anticreep effect is also not obvious, and therefore the structure of traditional Anti-disconnecting plug socket still must be improved.
Summary of the invention
The purpose of the utility model provides a kind of effective Anti-disconnecting plug socket rational in infrastructure, anti-loose.
The technical scheme that realizes the utility model purpose is: a kind of Anti-disconnecting plug socket comprises plug and socket; Said plug comprises plug casing and is arranged on the metal pin on this housing; Said socket comprises the Socket casing that is provided with jack and is arranged on the metal contact in this Socket casing, and the pin of said plug is plugged in the jack of said Socket casing and with the metal contact that sets within it and is electrically connected;
Also be provided with the anticreep spare that the pin that is used for preventing said plug gets loose from the jack of socket on this plug casing, this anticreep spare comprises the fixed part that extends outward from said plug casing and the connecting portion that extends to form along the pin direction towards plug from the outer end of fixed part;
The end of said connecting portion is provided with to the protruding clamping in its outside protruding; Be provided with trip with the protruding corresponding position of said clamping on the said socket, when the pin of said plug inserted in the jack of socket fully, said clamping convexity just in time was arranged in said trip.
In the technique scheme, said connecting portion is straight tabular, leaves the gap between the medial surface of this connecting portion and the said plug casing.
In the technique scheme, said trip comprises the vertical barrier plate that is provided with and extends towards the inboard with this location-plate of extended location-plate and the end that is arranged on this location-plate from the said Socket casing; The basic configuration that said location-plate and said barrier plate are formed trip is 7 fonts; Said clamping convexity is arranged in the draw-in groove that is surrounded by location-plate and barrier plate.
In the technique scheme, said anticreep spare is two and is symmetricly set on the relative position of said plug casing.
The utlity model has positive effect: in (1) the utility model; Through on the basis of traditional plug and socket, being provided with the anticreep spare that the pin that is used for preventing said plug gets loose from the jack of said socket, this anticreep spare comprise the fixed part that extends outward from said plug casing and from the outer end of fixed part along the connecting portion that extends towards the pin direction of plug; The end of said connecting portion is provided with to the protruding clamping in its outside protruding; Be provided with trip with the protruding corresponding position of said clamping on the said socket, when the pin of said plug inserted in the jack of socket fully, said clamping convexity just in time was arranged in said trip.Adopt this structure when operation, connect in the trip together through the clamping convexity is connected to, rational in infrastructure, can prevent effectively that also plug and socket from plug and socket slippage that improper action causes taking place simultaneously, effect is better.
(2) in the utility model, be straight tabular through adopting said connecting portion, the structure that leaves the gap between this connecting portion and the said plug casing makes the connecting portion of anticreep spare have mobilizable space; When inserting plug; To extruding is contracted to the spacing of the end of its connecting portion can to enter into trip near the direction of plug casing, when the back relieving that puts in place of the clamping convexity of the end of connecting portion, anticreep spare is promptly to rebounding away from the plug casing direction with anticreep spare; Because the effect of elastic force; The clamping convexity is arranged in trip reliably, only when artificial action, just can the clamping convexity be withdrawed from from trip, and this kind structure makes plug more reliable with being connected of socket.
