Abstract

The utility model relates to a two-wire or three-wire universal wall receptacle, which is composed of a skeleton, a box cover, contact pieces and a zero conductor box, wherein, the skeleton is provided with two empty slots used for mounting the dual-purpose contact pieces; the other side of the skeleton is provided with a groove formed by two convex used for mounting the contact piece of the ground wire. The dual-purpose contact pieces can contact a two-wire plug and can also contact a three-wire plug. The jacks of the box cover are tightly posted into butterfly shapes, and the jacks are suitable for round inserting pieces and flat inserting pieces. The contact pieces on the skeleton of the post-installation receptacle are corresponding to the jacks of the box cover, so that the work of the two-wire plug or the three-wire plug is reliable. The utility model has the advantages of compact structure and high safety, and is suitable for various home electric appliance plugs.

Description

Universal wall receptacle

A kind of appliance socket, particularly a kind of two lines circle, flat contact plug and all spendable wall safety socket of three-way flat contact plug.

Existing appliance socket kind is more, though two lines, the three-way socket that can both use are also arranged, arranges many cover jacks on this kind socket surface, makes external form bigger; Socket has selection for the contact of plug, and the plug of circle or flat contact can not be general on single cover jack.The ground wire of this kind socket is many with the insulating material wrapping, and design is not proper, thereby potential electric leakage is dangerous.Wall socket yet there are no two in addition, three-way can both the use.

The purpose of this utility model is small and exquisite, the safe in utilization Universal wall receptacle of a kind of external form of design.This socket all can use for two wires circle, flat contact and three-way flat contact plug.This socket is improved prior art, has still adopted contact to be fixed on the skeleton, and skeleton is placed in the zero line box, and the zero line lid has the lid of band jack.This Universal wall receptacle is characterised in that: skeleton is cuboid, and symmetry has the corresponding back side of two dead slots on one face respectively has a projection in dead slot lower curtate place, is an expansion shape groove in the middle of two projectioies, and groove is up-narrow and down-wide.Two wires, three-way shared dual-purpose contact are housed respectively in two dead slots.Contact one end stretches out outside the groove and contacts with the contact of three pin plug, stays the contact of dead slot end as the two wires plug.Part has certain drift angle (approximating 36 °) in the dual-purpose contact extension opposed slot.Channel bottom has a planker, and the ground wire contact is fixed on it.Dead slot and dual-purpose contact and groove and ground wire contact are done insulation and are isolated.Jack on the zero line lid is arranged to butterfly shape, and jack is all in a concentric circles, and circumferentially.With skeletal fixation on lid.And contact on the skeleton and the jack on the lid align, and form a complete socket.

The utility model is aesthetic in appearance, and compact conformation is reasonable, and is safe in utilization.

Provide embodiment of the present utility model below by accompanying drawing.

Fig. 1 is a band contact skeleton structure front view.Fig. 2 is the structure top plan view.Fig. 3 is that center section plan is looked on a skeleton left side.Fig. 4 is the lid front view.Fig. 5 is a lid back view.Fig. 6 is that center section plan is looked on a lid left side.Fig. 7 is skeleton and lid assembling schematic diagram.Fig. 8 is a band fixed touch plate skeleton vertical view.

Among the figure, the 1st, skeleton, the 2nd, ground wire contact, the 3, the 4th, dual-purpose contact, the 5,6, the 7th, lug plate, the 8th, screw sheet, the 9, the 10th, fixing auricle, the 11st, lid, the 12nd, screw hole, the 13rd, screw.

Referring to accompanying drawing, this Universal wall receptacle is made up of zero line box, skeleton (1) and lid (11) three parts.Two dead slot internal fixation of cuboid skeleton (1) have lug plate (5,6) and dual-purpose contact (3,4).Some stretches out dual-purpose contact (3,4) outside the dead slot, is used to contact three pin plug, and the dual-purpose contact (3,4) of staying dead slot is used to contact the two wires plug.The relative dead slot of extension partly has the entad drift angle about 36 °.Ground wire contact (2) is contained in the groove at the dead slot back side, is fixed on the planker of groove bottom.Promptly have three-way jack that two line jacks are arranged again on the lid (11), two line jacks all are suitable for round end or homalocephalus inserted sheet again.Skeleton (1) is screwed on lid (11) by screw hole (8).Lid (11) is fixed on the zero line box by hole (12) again, and makes skeleton (1) place the zero line box.The zero line box adopts the most common common a kind of.Blanket socket after the assembling, its contact (2,3,4) should be corresponding corresponding with all jacks on the lid (11), makes two wires or the three pin plug can both operate as normal.

Utilize skeleton (1) can also make other kind blanket socket.As shown in Figure 8, skeleton (1) bottom has fixedly auricle (9,10), socket can be fixed on other object by the hole on the auricle (9,10) like this, is not limited to fixedly on the wall, and is more flexible multi-purpose.

Claims

1, a kind of contact is fixed on the skeleton, and skeleton places the zero line box, and lid has the Universal wall receptacle of two wires or three-way jack, it is characterized in that:

A. be on the face of cuboid skeleton, symmetrical center line has two dead slots, on the corresponding back side two projectioies is arranged, and is an expansion shape groove in the middle of the projection,

B. the dual-purpose contact front end installed of dead slot stretches out outside the groove, extension relatively not extension have certain entad drift angle,

C. channel bottom has the fixing planker used of ground wire contact.

2, Universal wall receptacle according to claim 1 is characterized in that groove and dead slot do insulation and handle.

3, Universal wall receptacle according to claim 1 is characterized in that the jack on the capping is arranged to butterfly shape, and whole jack is in a concentric circles.
