Description

A kind of socket and pin thereof

Technical field

The utility model relates to the power supply unit technical field, particularly a kind of socket and pin thereof.

Background technology

Socket is the electric equipment that power interface is provided for household electrical appliance, also is to use more electrical accessory in the residential electricity design, and it and people's life have very confidential relation.

Please refer to Fig. 1 and Fig. 2, Fig. 1 is the structural representation of a kind of socket of the prior art; Fig. 2 is the structural representation of the pin of a kind of socket of the prior art.

The pin of being made by metallic laminas 3 is set on socket 2 usually, and pin 3 is connected with power line, and attaching plug 1 makes the ferrule of attaching plug 1 contact with pin 3 conductions, thereby reaches the effect to the attaching plug power supply through being connected with socket.

As shown in Figure 2, the socket of pin 3 is the U type, and the ferrule of attaching plug 1 contacts conduction with its U type inwall, and relies on the elastic force of socket to clamp the ferrule of attaching plug 1, thereby makes attaching plug 1 be fixedly connected with socket 2.

But; Owing to need often peg graft or extract attaching plug 1, the elasticity of the pin 3 that causes being made by metallic laminas weakens, and it is loosening that attaching plug 1 socket of pin 3 occurs through regular meeting in use for some time; Cause attaching plug 1 grafting socket 2 illusive situation; When serious even ferrule and pin 3 loose contacts of attaching plug 1 take place, cause socket 2 can't continue application, shortened the useful life of socket 2.

Therefore, how improving the socket elasticity of pin, is those skilled in the art's problem demanding prompt solutions the useful life of prolong socket.

The utility model content

In view of this, the utility model provides a kind of socket and pin thereof, to improve the socket elasticity of pin, the useful life of prolong socket.

For realizing above-mentioned purpose, the utility model provides following technical scheme:

The utility model provides a kind of pin; Comprise the pin body; Said pin body has power supply connecting portion that is connected with the power line conduction and the socket that is connected with the attaching plug conduction, also comprises being arranged at the said socket outside, is used for inwardly clamping the spring clip of socket walls.

Preferably, said spring clip is the steel spring clip.

Preferably, said spring clip is the wire spring folder by the steel wire bending.

Preferably, said spring clip is arranged on the curved wall of said socket.

Preferably, said pin body is the brass pin.

The utility model also provides a kind of socket, and said socket comprises at least two pins, has at least one to be the described pin of above-mentioned arbitrary scheme in the said pin.

Can find out that from above-mentioned technical scheme socket that the utility model provides and pin thereof are at the spigot increase spring clip of pin; Through the clamping action of spring clip, make the elasticity of socket be difficult for weakening, improved the elasticity clamping force of socket clamping attaching plug; Be difficult for loosening after itself and attaching plug are pegged graft; Improve splicing stability, made functional that socket and attaching plug conduction contacts, thereby effectively prolonged the useful life of socket.

Embodiment

The utility model discloses a kind of socket and pin thereof, to improve the socket elasticity of pin, the useful life of prolong socket.

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Please refer to Fig. 3 and Fig. 4, the structural representation of the socket that Fig. 3 provides for the utility model embodiment; The structural representation of the pin of the socket that Fig. 4 provides for the utility model embodiment.

The utility model embodiment provides a kind of pin; Comprise pin body 3, the pin body has power supply connecting portion 31 that is connected with the power line conduction and the socket 32 that is connected with the attaching plug conduction, and it focuses on; Also comprise being arranged at socket 32 outsides, inwardly clamp the spring clip 4 of socket walls.

The pin that the utility model embodiment provides increases spring clip 4 at socket 32 places of pin, through the clamping action of spring clip 4; Make the elasticity of socket 32 be difficult for weakening; Improved the elasticity clamping force of socket 32 clamping attaching plugs, it is loosening that itself and attaching plug grafting back are difficult for, and improved splicing stability; Make functional that socket 2 and attaching plug conduction contacts, thereby effectively prolonged the useful life of socket 2.

In the pin that the utility model embodiment provides, spring clip 4 is the steel spring clip.Because steel has more stable performance, elasticity is stronger and not yielding, in prolonged application, is difficult for forfeiture elasticity, feasible socket 32 elastic stabilities that are provided with spring clip 4.

The manufacturing of spring clip 4 for ease is set to the wire spring folder by the steel wire bending with spring clip 4.As shown in Figure 4, the end of steel wire all is provided with bending section, and the wire spring folder that can easily steel wire be bent is plugged in socket 32 outsides.

As shown in Figure 4, in the process of pegging graft for fear of attaching plug and socket 2 with spring clip 4 mutual friction mutually take place, spring clip 4 is arranged on the curved wall of socket 32.Design friction between itself and the spring clip 4 when having reduced the socket power plug like this, thus the frictional dissipation of spring clip 4 reduced, the useful life of further having improved socket 2.

Pin in the present socket generally adopts good silver-bearing copper of electric conductivity or brass material to make.Relative brass material, silver-bearing copper has elasticity preferably, but price is higher, and the socket cost that causes using silver-bearing copper material manufacture pin is higher; The cost of brass pin is lower, but because brass elasticity is relatively poor, very easily occurs the loosening situation of plug after use a period of time, and useful life is shorter.In the embodiment of the utility model, preferentially select for use the more cheap relatively brass of price to make pin body 3.Owing to increased spring clip 4, improved the elasticity of the socket 32 of pin, loosening situation behind the difficult generation socket power plug, useful life is longer relatively; Also can not make the whole cost of pin too high, practicality is stronger.

The utility model also provides a kind of socket 2, and socket 2 comprises at least two pins, and it focuses on, and has at least one to be above-mentioned any pin in the pin.

Only a pin is set to above-mentioned pin with spring clip 4, the useful life that reaches prolong socket 2, effectively reduces the production cost of socket 2; Also can a plurality of pins all be set to have the pin of spring clip 4, make the resistance to overturning of socket 2 higher, longer service life.

Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
