Abstract

The utility model discloses a general power-supply socket. The cross section of conductive contact chips in the jacks of the socket are all in the * shape. Not only the utility model is suitable for plugs in various types, but also the utility model has good contact performance, simple structure, and low cost.

Description

General power-supply socket

The utility model relates to a kind of supply socket, particularly a kind of universal supply socket that is suitable for dissimilar plugs.

At present, the popular plug that various household electrical appliance adopted can be divided into four classes basically on the market: (1) erects the flat plug; (2) oblique flat plug; (3) horizontal flat plug; (4) cannon plug.More than each plug must use the socket that is complementary, and the employed socket of general house or office only is only applicable to one, two kind of plug.This has brought inconvenience to the user.

Chinese patent CN2158142Y discloses a kind of multi-function jack, and its socket cover is provided with a rotating disk, and a plurality of jacks that distribute below the rotating disk are selected corresponding jack by mobile rotating disk.This socket complexity, and use inconvenience.

Chinese patent CN2135199Y discloses a kind of multi-purpose socket, and the inserted sheet cross section in its jack is

Shape.It has solved a jack with regard to applicable this difficult problem of polytype plug.But the inserted sheet of this shape will be made up of five parts, and difficulty of processing is bigger, and structure is unreasonable.

Goal of the invention of the present utility model is to overcome the defective that above-mentioned technology exists, and provides an a kind of jack promptly applicable to the polytype plug, and universal supply socket rational in infrastructure.

Goal of the invention of the present utility model is achieved in that on the basis of existing power supply socket, the cross section of the conduction contact chip in jack and the jack is " " or "

" shape.

For the ease of the insertion of plug or extract, have a vertical narrow slit in the vertical side walls upper end of the contact of " L " shape, and " " and "

" bottom of contact of shape connects as one, the spacing of itself and plug contact portion is less than its spacing with the lower part.In addition, the openend of conduction contact chip is toroidal and outwards opens.

Technical solutions of the utility model are except being fit to various plugs, and its contact performance obviously is better than existing scheme, and simple in structure, and cost is low.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model conduction contact chip;

Fig. 2 is the transverse sectional view of the utility model Fig. 1 and the position view of plug when using.

Referring to Fig. 1 and Fig. 2.Openend be the outside open conduction contact chip of toroidal (1) by the L-shaped contact in cross section (2) and "

" contact (4) form.Have narrow slit (3) on " L " contact (2), and "

" spacing between contact and the plug contact portion (5) is less than its spacing with lower part (6).The bottom of contact (2), (4) connects as a whole (7).

When plug is columniform, plug is in the position of (8), the face of its contact be " " arcwall face of shape contact; When plug was oblique flat plug, plug was in the position of (9), the face of its contact be " L " contact (2) corner and "

" the long-diagonal place of shape contact (4) arcwall face; When plug was vertical plug, plug was in the position of (10), and the face of its contact is the inner surface of " L " contact; When plug during for plug anyhow, plug is in the position of (11), the face of its contact be "

" inner surface of parallel portion of shape contact.Like this, with regard to having solved the problem that a kind of socket is suitable for various plugs, provide users with the convenient.

Claims

1, a kind of universal supply socket is characterized in that: in the jack cross section of conduction contact chip (1) be "

" or "

" shape.

2, universal supply socket according to claim 1 is characterized in that: the vertical side walls upper end of " L " shape contact (2) in the chip (1) has a vertical narrow slit (3), "

" or "

" with the spacing between lower part (6), and bottom (7) connect as a whole less than it for spacing between the part (5) that contacts with plug of shape contact (4).

3, universal supply socket according to claim 1 and 2 is characterized in that: the opening part of chip (1) is toroidal and outwards opens.

4, universal supply socket according to claim 3 is characterized in that: " L " shape contact (2) and "

" or "

" bottom of shape contact (4) is the conducting strip of an integral body.
