Abstract

The invention discloses a plug bush which comprises a conductive plate, wherein clips are symmetrically arranged at two sides of the upper part of the conductive plate; the clips are fixedly connected with the conductive plate through screws; a clamping part of the plug bush is formed by the two clips; a bolt is connected with the lower part of the conductive plate; the plug bush is characterized in that spring plates are arranged at the outer sides of the clips respectively; and the spring plates are fixedly connected with the conductive plate. According to the invention, by additionally arranging the spring plates outside the clips, the clips are used for well clamping; moreover after the plug bush is subjected to long-term use, the clips can still be tightly contacted with insertion plates; and the plug bush remains effective after the long-term use.

Description

A kind of sleeve

Technical field

The present invention relates to a kind of product that is electrically connected function that has, be specifically related to a kind of sleeve.

Background technology

In daily life, socket is a kind of electric equipment commonly used, is called supply socket, combined socket and switch again; One or the insertable seat of above circuit connection have been meant; Can insert various wiring through it, be convenient to identical with other circuit, all supporting sleeve that is provided with in the socket.

In the market; Sleeve structure commonly used is to form conductive copper plate by conductive material punching presses such as elastomeric beryllium-bronzes referring to shown in Figure 1, and this conductive copper plate 1 generally is the setting of L type; The intermediate plate 2 of a copper alloy is set in the upper end bilateral symmetry of L type conductive copper plate; Two intermediate plates are the setting of U type through screw 3 both sides that fixedly are fitted in conductive copper plate tightly, and the lower end of L type conductive copper plate is connected with the interior copper coin of socket through screw.Sleeve is inserted the public affairs end inserted sheet that width reaches 1.6mm between two intermediate plates by the outside in use, and intermediate plate carries out clamping to inserted sheet, and forms a conductive path with the socket conducting, supplies power.

Yet find that in the use of reality there is a bigger deficiency in this sleeve, sleeve is after using through long-term plug; Himself elasticity of intermediate plate can be lost gradually; Can't keep enough resilience forces, finally make intermediate plate closely to contact, cause sleeve to lose efficacy with inserted sheet.

Summary of the invention

It is better that the object of the invention provides a kind of chucking power, and the sleeve that can not lose efficacy after long-term the use.

Technical scheme of the present invention is: a kind of sleeve; Comprise a conductive plate, said conductive plate top bilateral symmetry is provided with intermediate plate, and said intermediate plate is fixedly connected with said conductive plate through screw; Said two intermediate plates constitute the clamping part of sleeve; Said conductive plate bottom is connected with bolt, and said two intermediate plates outside is respectively equipped with shell fragment, and said shell fragment is fixedly connected with said conductive plate.

Further technical scheme, said screw runs through said shell fragment, constitutes being fixedly connected of said shell fragment and said conductive plate.

In the technique scheme, said sleeve comprises that is the conductive plate that the L type is provided with, and is generally the beryllium-bronze conductive material and constitutes; Bilateral symmetry is provided with intermediate plate on the top of conductive plate; Intermediate plate is connected the both sides of conductive plate through screw, and the bottom of conductive plate is connected with bolt, and this bolt is used for sleeve is connected with conductive plate in the socket; The outside conduction inserted sheet that inserts plugs between two intermediate plates, forms conductive path.The present invention is through setting up a shell fragment respectively in the intermediate plate outside, and shell fragment is fixedly connected with conductive plate through screw, and this shell fragment can adopt the good stainless steel of elasticity to constitute; Can form protection to sleeve; Increased the chucking power of intermediate plate simultaneously, and because himself elasticity is better, after long-term the use; Resilience force is preferably still arranged, guaranteed that intermediate plate can contact with the inserted sheet that inserts closely.

Advantage of the present invention is:

1. the present invention is through setting up shell fragment in the intermediate plate outside, and this shell fragment has elasticity preferably, and after sleeve was through long-term the use, shell fragment still had resilience force preferably, has guaranteed that intermediate plate can contact with inserted sheet closely, and sleeve is still effective after long-term the use;

2. the present invention is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

Fig. 1 is a sleeve structural representation in the prior art;

Fig. 2 is the structural representation of the embodiment of the invention one;

Fig. 3 is the structure cutaway view of the embodiment of the invention one.

Wherein: 1, conductive copper plate; 2, intermediate plate; 3, screw; 4, conductive plate; 5, intermediate plate; 6, screw; 7, bolt; 8, shell fragment.

Embodiment

Embodiment one: referring to Fig. 2, shown in 3, a kind of sleeve comprises a conductive plate 4; Said conductive plate 4 top bilateral symmetry are provided with intermediate plate 5, and said intermediate plate 5 is fixedly connected with said conductive plate 4 through screw 6, and said two intermediate plates 5 constitute the clamping part of sleeve; Said conductive plate 4 bottoms are connected with bolt 7; Said two intermediate plate 5 outsides are respectively equipped with shell fragment 8, and said screw 6 runs through said shell fragment 8, and formation shell fragment 8 is fixedly connected with conductive plate 4.

Sleeve inserts inserted sheet between two intermediate plates in use, constitutes conductive path; After finishing using; Inserted sheet is extracted, because shell fragment has resilience force preferably, can guarantee after intermediate plate is through long-term the use still can homing; Guaranteed contacting of intermediate plate and inserted sheet, it is still effective after using that sleeve is long-term.

The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
