Abstract

The utility model provides a series of plugs of which the pins can be suitable for various round and flat jacks. Inserting handles control the pins to be randomly positioned and controls redundant pins not be inserted to sockets so as to make one plug be able to be suitable for various types and sizes of sockets. The pins and the inserting handles have elasticity so as to make the plugs be stably inserted. The universal electric plug has easy manufacture and low cost.

Description

Universal electric plug

The utility model is a kind of being connected on the electrical appliance, can be suitable for the Universal plug of various supply sockets.

Socket hole count commonly used has two, three and four, hole shape cyclotomy and flat, the pitch of holes hole arrange different make socket varied (Fig. 1. the hole of several sockets).General plug can only be suitable for a kind of socket, and people often run into plug and insert the trouble of not going into socket.The plug that No. 85202713, Chinese patent.One of its pin is movable, but 2 millimeters of translations and tilting tens millimeters, but the pin activity makes and pegs graft unstablely, and pin tilts pin can not all be inserted, and this plug can not be gone into circular hole and the flat hole of splayed.No. 85205376, Chinese patent and No. 64949 purposes of Taiwan patent are to enlarge the socket applicability, but can not be suitable for various plugs.In addition, also have patent to improve splicing stability specially.

The purpose of this utility model is to solve simultaneously the supporting and grafting steadiness problem of plugs and sockets.The pin of application object is flat or compressible for flat, can insert flat hole like this, flexible of pin (silk), and inflatable compression can be suitable for the various apertures of circular hole; One end of every pin is wrapped up by a column, connects with definite shape between the column, and connector and column are formed inserting handle.The form of pin (Fig. 2. various pins) have: the date core shaped that elastic metallic yarn surrounds (a), two metal sheets embed on column (b), long-bar metal sheet thick (wide) the degree direction with the scissors shape and are connected with elastic sheet (c, d), integral body stamps out flexure strip (f) on the long-bar metal sheet.The form of inserting handle has: the combination of the shape of a hoof (Fig. 3), die Schwimmhaut shape (being used for two-pin plug) " Y " font (being used for three-pin plug), " ten " font (being used for four-pin plug), separate type (the various inserting handles of Fig. 4) and Fig. 3 Fig. 4 form.

The advantage of application object has three: pin can be located arbitrarily, three, four-pin plug can do two, three-pin plug is all flexible with, inserting handle pin, make peg graft firm.

Embodiment one.As Fig. 3, inserting handle is that the shape of a hoof, two row's grooves can make the pin left-falling stroke be splayed, pin such as Fig. 2 a.

Embodiment two.The hot pressing of scissors shape pin by the elasticity opening and closing of handle, is closed when covering and can be inserted the roundlet jack in inserting handle, can be suitable for the great circle jack when opening, and pin is thick to be same as general flat pin.A pin and a column are a plug, are connected with a lead, and one group of several plug are shared.

Claims

1, a kind of attaching plug is characterized in that, flat maybe can be pressed into flexible of the pin (silk) of flat, inflatable contraction.
