The present invention relates to a kind of U-shaped plug, including shell and pin, shell includes upper housing and lower case, shell is a resiliently deformable extension, various types socket can be matched by adjusting the spacing between two pins, and the U-shaped pull ring shape of shell can extract it with singly referring to after plug is inserted into power supply.Upper housing and lower case are detachably connected, wiring hole is respectively equipped on top and shell two sides after upper housing and lower case combination, shell U-shaped opening both ends form pin pipe, metal sleeve is set in pin pipe, pin slot is arranged in front end, pin is connected through a screw thread with metal sleeve in pin slot, and being equipped with open socket slot in pin slot end can realize that multiple plug head and the tail connect.

Description

A kind of U-shaped plug

Technical field

The present invention designs electrical accessorie field more particularly to a kind of plug.

Background technique

Plug is a kind of male member, can complete to be electrically connected by being inserted into socket, is connected as electric equipment products The accessory for connecing power supply is used widely in people's daily life.Currently, the part of traditional plug up to 11, plug is with inserting Seat is one-to-one relationship, i.e. a plug can only match a socket and use, when needs connect two on a socket Electric equipment products need to connect using socket, and the plug of same specification can only be used in the socket of same size.

Summary of the invention

It is an object of the invention to be directed to the existing state of the art, a kind of U-shaped plug is provided, solves above-mentioned background to realize Technical problem.

In order to achieve the above objectives, the present invention adopts the following technical scheme:

The present invention is a kind of U-shaped plug, including shell and pin, the shell include upper housing and lower case, the shell The U-shaped pull ring type of body, top and two sides are equipped with electric wire insertion holes, and U-shaped opening is equipped with pin pipe.

Further, shell is TPE thermoplastic elastomer (TPE) material, and U-shaped connecting pin is slightly narrow pipe type, open end opening terminal drum It rises, opening maximum can stretch out 0.5cm.

Further, upper housing is an integral molding structure respectively with lower case, and upper housing and lower case are clamped by pairing Connection.

Further, pin pipe includes socket slot and pin slot, and pin slot is set to pin pipe front end and pin end Matching, the socket slot are set to pin pipe end and match with pin front end.

Further, metal sleeve is provided in upper housing pin pipe, metal sleeve is sleeved in pin pipe, metal sleeve It is interior to be equipped with screw thread, to be attached fixation with pin.

Further, upper housing pin pipe is provided with electrical connection fixed strip, and electrical connection fixed strip and upper housing are TPE thermoplastic Property elastomer material is annularly arranged on the outside of upper housing pin slot open portion.

A kind of U-shaped plug provided by the invention can be realized following technical effect:

1, U-shaped plug is made of 3 upper housing, lower case and pin components, cost of manufacture simpler compared with traditional plug structure It substantially reduces；

2, by being connected together, the power supply wiring of electric appliance can directly use the metal of upper housing for U-shaped plug upper housing and lower case Casing is fixed, and the tool of not needing can carry out plug connection, and use is easy to operate；

3, the pull ring design of U-shaped plug, which refers to user singly, can extract plug from the socket of connection, facilitate people Routine use；

4, U-shaped plug casing is made of elastomer material, in addition the U-shaped design that pin pipe is higher than shell makes pin can parallel flexible Stretching, extension, can be used plug in the socket of various different systems；

5, U-shaped plug is modularized design, and pin pipe end utility receptacles slot can be inserted directly into other plugs, can make multiple Plug is connected to same socket without using socket simultaneously.

Detailed description of the invention

Attached drawing 1 is the main view of the present invention；

Attached drawing 2 is the side view of the present invention；

Attached drawing 3 is the bottom view of the present invention；

Attached drawing 4 is the structure chart of the present invention.

Specific embodiment

In order to enable juror to be further understood that the purpose, feature and function of the present invention, hereby lifts and preferably implement Example simultaneously cooperates schema detailed description are as follows:

It please referring to shown in Fig. 1 ~ Fig. 4, is the structural schematic diagram for the preferred embodiments of the invention, the present invention is a kind of U-shaped plug, Including shell and pin 3, the shell includes upper housing 1 and lower case 2, the U-shaped pull ring type of shell, top and two Side is equipped with electric wire insertion holes 4, and U-shaped opening is equipped with pin pipe 7.

Upper housing 1 and lower case 2 are respectively the integrated formed structure of TPE thermoplastic elastomer (TPE) material, pass through mold one Injection molding molding, TPE thermoplastic elastomer (TPE) are a kind of polystyrene thermoplasticity material, pass through s-B-S Triblock copolymer (also referred to as SEBS) is substrate, by composite modified acquisition, have good thermoplastic elastomer (TPE) intensity and Wearability, for the environment-friendly materials of multi-functional purposes.U-shaped shell connecting pin is that slightly narrow pipe type, open end open end is heaved, pin Pipe 7 protrudes from upper housing, is open maximum stretchable extension 0.5cm by the torsion of the U-shaped interconnecting piece pin pipe 7 that deforms.

Upper housing 1 and 2 edge of lower case are equipped with card interface, upper housing 1 and lower case 2 and are clamped connection by pairing, realize Easily can combine and decouple structure, the card interface part of upper housing 1 and 2 top of lower case and two sides respectively there are semicircle groove, It combines and constitutes circular electric wire insertion holes 4.

The opening of upper housing 1 is equipped with pin pipe 7, and pin pipe protrudes from upper housing, and pin pipe end is complete tubular socket Slot 5, front end are halfpipe, and the electrical connection fixed strip 9 of annular is equipped on the outside of halfpipe.Lower case U-shaped opening end is equipped with half cast Groove forms pin slot 6 with upper housing pin pipe.Tubular metal sleeve pipe 8 is set in upper housing pin pipe 7, in metal sleeve 8 Equipped with screw thread.

Pin is formed and is made of fully automatic roll type electroplating technology, electroplated layer using turnery processing by the high-precision copper material in H62 ~ 65 It is not easily to fall off.3 end of pin is provided with screw thread, and pin 3 is connected with shell by 8 internal screw thread of metal sleeve.

Plug carries out that electric wire is only needed to be linked into upper housing 1 from electric wire insertion holes 4 when wiring, and pin 3 is rotated into slotting Foot slot 6 is attached electrical connection and pin 3 using electrical connection fixed strip 9, and upper housing 1 and lower case 2 are combined i.e. It can.

Certainly, illustrated above is only better embodiment of the present invention, and use scope of the invention is not limited with this, therefore, It is all made in the principle of the invention it is equivalent change should be included within the scope of the present invention.
