Description
Technical field
The utility model relates to a kind of electrical appliance, particularly relates to a kind of supply socket with emergency exit.
Background technology
Commercially available a kind of multifunctional power socket with safety protection function; when the two pins of L, the N of the plug of its same system are inserted in L on the panel, the N jack; when touching single shutter and overcoming the thrust of back-moving spring; shutter promptly leaves the position of sealing jack along slide rail, and the two pins of L, N are entered pedestal and realize being electrically connected normally with sleeve component.Extract pin, shutter returns the position of sealing jack at the thrust lower edge of back-moving spring slide rail, thereby has safety protection function.But when single pin or single foreign matter insert when touching shutter and overcoming the thrust of back-moving spring, single pin or single foreign matter can enter pedestal too and contact with sleeve component.When using the supply socket of above-mentioned structure in the family; if child do not note because of curiosity or adult, when single pin or single foreign matter are inserted socket, electric shock accidents will take place; jeopardize people's life security, the safety protection function when therefore the supply socket of above-mentioned structure is worked is incomplete.
Chinese patent ZL96243408.8 discloses a kind of emergency exit structure of supply socket, and it comprises a framework that is rectangle, and two are to spin taper and be configured in upper and lower slide block and two in the framework and place upper and lower spring between edge and the upper and lower slide block.When two pins of electrical appliance plug inserted the utility model emergency exit, this door can be opened easily.When plug was extracted from socket, emergency exit can be closed automatically.When a metallic conductor touches emergency exit, spin conical sliding block owing to monolateral stressed the tendency on one side, the projection that slide block just in time is set up is pinned and can not be moved, thereby plays safety effect.This emergency exit structure is installed between the metallic conductor connector and jack housing jack of socket, and parts are many, processing request is high.
Summary of the invention
The utility model provides a kind of supply socket with emergency exit, and this socket only allows two pins of L, N of homologous ray plug to insert simultaneously, does not allow single pin or single foreign matter to insert with charged sleeve component in the pedestal and contacts.
The technical solution of the utility model is: a kind of supply socket with emergency exit, comprise the cover plate of being with jack, with the pedestal that cover plate flexibly connects, be provided with shutter between described cover plate and pedestal, the corresponding one side of shutter both sides and jack is respectively equipped with the inclined-plane; Described pedestal is provided with slide rail, and the pedestal both sides are provided with two pedestal boss; Two cover plate boss of relative set on the inner surface of cover plate; Passing through apart from holding shutter just between the upper and lower of pedestal boss and cover plate boss; Shutter middle part is provided with the chute that is complementary with slide rail, and the shutter front end face is provided with cylindrical projection, and stage clip is housed on the cylindrical projection, the described stage clip other end be contained on the pedestal with the corresponding projection of cylindrical projection on; The thrust of stage clip is in shutter and seals on the position of jack.
The inclined-plane of described shutter becomes stairstepping, and the outer end is higher than the inner; The back side of shutter also becomes stairstepping, and the thickness of its outer end is less than inner thickness.
Slide rail on the described pedestal is a face of cylinder slide rail, and the shutter middle part is a face of cylinder chute with the chute that slide rail is complementary.
The utility model supply socket is provided with shutter device, compact conformation, easy for installation between cover plate and pedestal.Utilize the mutual cooperation of cover plate, pedestal and shutter to make single pin or foreign matter when jack touches shutter; shutter is stopped by the boss that is provided with on cover plate and the pedestal and can't open, and has stopped the contacted possibility of charged sleeve component in single pin or foreign matter and the pedestal fully.Safety protection function during the utility model work is complete, reliability is high.

Embodiment
As Fig. 1, Fig. 2, the utility model supply socket comprises cover plate 1 and pedestal 2, and cover plate 1 and pedestal 2 are interlocked, and cover plate 1 is provided with multi-functional jack 3, and inner surface is provided with two cover plate boss 4.
As Fig. 3, pedestal 2 is embedded with the metallic conductor sleeve component, and pedestal 2 is provided with face of cylinder slide rail 6, and pedestal 2 both sides are provided with two pedestal boss 7; Pedestal 2 front ends are provided with the projection 5 that can place spring.
As Fig. 4, Fig. 5; shutter 8 middle parts and the corresponding one side of pedestal be provided with pedestal 2 on the face of cylinder chute 11 that is complementary of face of cylinder slide rail 6; the jack 3 corresponding one sides of shutter 8 both sides and cover plate 1 are respectively equipped with inclined-plane 10, the cylindrical projection 9 that the shutter front end face is provided with.
As Fig. 6, Fig. 7, be the another kind of execution mode of shutter 8, the 10 one-tenth stairsteppings in the inclined-plane of shutter 8, outer end 10b is higher than inner 10a; The back side of shutter 8 also becomes stairstepping, and the thickness of its outer end is less than inner thickness.This shutter structure can strengthen the gradient of shutter 8, in case after making that shutter tilts, blocked by pedestal boss 7 and cover plate boss 4 easily.
As Fig. 8, shutter 8 is installed between cover plate 1 and the pedestal 2.Pedestal boss 7 and cover plate boss 4 between the upper and lower apart from can hold shutter 8 just and pass through; The width of the spacing of two pedestal boss 7 and shutter 8 adapts, and generally is slightly less than shutter 8 width; The stage clip 12 of packing on the cylindrical projection 9 of shutter 8, the other end of stage clip 12 is shelved on the projection 5 of pedestal 2, the position that the thrust of stage clip 12 is in shutter 8 to seal L on the cover plate 1, N jack 3.
As Fig. 9, the utility model can apply in the various supply sockets with multi-functional jack, but several be arranged in together, can be used for the multidigit conversion socket, in the various forms of sockets such as wall socket, circular socket.
The shutter of the utility model supply socket is positioned on the position of sealing L, two jacks of N at ordinary times; the L of homologous ray plug, N two pins enter and touch the inclined-plane 10 at shutter 8 two ends during work; shutter 8 keeps balance; both sides are on the sustained height; when the strength of plug insertion can overcome the pressure of stage clip; shutter slips off along face of cylinder slide rail, and the pin of plug enters in the pedestal and realizes being electrically connected normally with sleeve component.Plug is when extracting in the socket, and shutter resets to the position of sealing L, two jacks of N again along slide rail under the effect of stage clip pressure.When single pin or foreign matter when L or N jack touch an end inclined-plane 8 of shutter 8; shutter 4 both sides around the face of cylinder of pedestal 2 slide rail 6 to lopsidedness; shutter 8 leading flank is on one side blocked by the pedestal boss 7 of pedestal 2; the another side of shutter 8 is also blocked by the cover plate boss 4 on the cover plate 1; single pin or single foreign matter can not be pushed shutter 8 open and enter in the pedestal 2 and contact with sleeve component, thereby reach the purpose of safeguard protection.
