Description

A kind of supply socket

Technical field

The utility model belongs to the electrical fitting technical field, particularly a kind of safe and reliable supply socket.

Background technology

At present, be used for the socket (plate) of power source connection system, rely on the elasticity of socket (plate) reed mostly or spring is set after Die for Reeds of Connector Jack plug is locked, perhaps rely on the design of socket (plate) pass that plug is fixed.Above-mentioned socket (plate) reed is to plug the elastic construction design of doing for adapting to plug, and it is the connection of point or line with being communicated with of plug, and contact resistance is bigger than the face contact, and it is serious to generate heat in the energising running.Heating frequently plugs plug in addition, causes distortion of socket (plate) reed and elastic failure easily, and contact condition is further worsened, and causes loose contact, sparking (gap discharge), also can cause the consequence of burning socket when serious.The poor reliability of socket, useful life is short.Have in the existing safety socket (plate) and adopt valve to design, require great effort during plug, socket (plate) is fragile.In being electrically connected of important events, have and adopt aviation plug, also have and adopt on the computer with spininess hole plug, the locking of above plug and socket relies on the realization that is spirally connected of screw and nut, the reliability that is communicated with relies on the spininess hole to increase contact point or contact wire guarantees, processing technology is relatively poor, can not the fast insert-pull break-make in the use, and versatility is poor.

The utility model content

The utility model purpose is to provide a kind of socket reliable, easy to use that contacts; Its further purpose is to provide a kind of reliable, easy to use and safe supply socket that contacts.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of supply socket, the base that comprises the band edge frame, frame top is equipped with the lock cam of band handle by bearing pin, be provided with the V-shaped T type locked groove in bottom in the base below the lock cam, be provided with the V-shaped T type lock core in the bottom that can slide up and down in the locked groove, between lock core and the locked groove both upper ends thereof return springs is installed, have vertical gap in the middle of the lock core, gap correspondence position and both sides, locked groove V-shaped part are respectively equipped with plane ground wire, zero line, the firewire binding post of mutual isolation in the base.

Establish the live wire connector lug in the base top, T type lock core upper end is connected with the horizontal break-make reed that an end is connected with the live wire joint, and break-make reed end in addition can join sheet upper end pressure with live wire and touches, and live wire joins the sheet line binding post of starting to exchange fire; T type locked groove inboard, binding post side are provided with the elasticity spacer pin vertical with base.

T type locked groove both upper ends thereof is provided with platform, and the locked groove inboard is provided with the dividing plate contour with platform, and T type lock core is arranged on platform and the dividing plate; Be provided with limiting plate below locked groove V-arrangement section inboard, the lock core, all establish elastic reset spare between limiting plate bottom surface and the base, limiting plate both sides correspondence up and down respectively are provided with a pair of spacer pin; Lock core gap lower width is less than upper width.

Socket panel is provided with the cam handle hole.

In the utility model, except that electric-conductor, make by ambroin.The design of adopting T type lock core to cooperate with T type locked groove, in the plug insertion socket jack after, rotating cam drive T type lock core is descending, and plug is closely contacted with socket midplane binding post.Owing to adopted the face contact, contacted effective; The micro-deformation of rectifiable plug contacts reliable simultaneously; Because the locking effect of lock core connects firmly, is difficult for loosening; Heating is few, sparking can not occur and burn socket danger; Binding post adopts existing design to get final product, and processing technology is simple.When the horizontal break-make reed of connection on employing T type lock core on the above-mentioned design basis, when the design of elasticity spacer pin being set in T type locked groove inboard, an elasticity spacer pin that only plugs in is depressed, T type lock core just can be descending under cam driven, plug is contacted with the Die for Reeds of Connector Jack close and firm, connect the live wire energising simultaneously.After lifting cam handle, the cam disengages lock core, lock core is up under the return springs elastic reaction, disconnects the live wire deenergization, pulls out plug, and the elasticity spacer pin ejects.Even this moment rotating cam, lock core can not be descending, power supply can not be connected, the metalwork in the receptacle sockets is not charged, can not get an electric shock even touch because of carelessness yet, fail safe is good.Do not have coupling mechanism force in plug during plug, plug more surely, can not damage working of plasticss such as housing face-plate.
