Abstract

The utility model relates to an earphone socket contact structure, which is composed of a socket 3, a holding groove 31, a multi-component double contact terminal strip 4 and an inclination strip 41, wherein, the multi-component double contact terminal strip 4 is arranged at the position of the holding groove 31, forming a stable assembly body, a cover plate 32 is arranged at the back of the terminal strip 4, the involutorial socket 3 forms a sealing shape, and is relative to the terminal strip 41, to ensure that the socket has the preferred transmission effect after being inserted in the earphone, and the sound efficiency of the earphone is improved.

Description

The earphone socket contact point structure

Technical field

The utility model relates to electric type, and particularly a kind of earphone plug socket contact point structure mainly comprises a jack body and a cover plate, provides placement with many groups two point terminal plate, forms firm assembly.

Background technology

General earphone socket as accompanying drawing 1 to shown in the accompanying drawing 3, include an integrated body 1, one end is an earphone inserting column patchhole 11, and be preset with array embedded hole 12 on the body 1, terminal plate 2 and two flexure strips 21 are provided respectively, 22 snap in, for being to form multiple spot with the earphone inserting column to contact, obtain basic leading note effect, common structure is because terminal plate 2 and flexure strip 21, the 22nd, the simple embedded hole that snaps in body 1 12 there is no other firm structures, therefore get loose easily or drop out, and

flexure strip

21,22 all only have the form of single-point contact earphone inserting column, also cause the not good of its leading note effect, easily produce the shortcoming of loose contact.

Content of the present utility model

The utility model is the shortcoming that exists at above-mentioned general earphone socket, and provide a kind of earphone socket contact point structure, it includes a jack body and a cover plate, utilize many group two point terminal plates, form firm assembly, and mat opposing inclined sheet makes socket after the earphone inserting column inserts, and has preferable laser propagation effect, improves the leading note efficient of earphone.

Embodiment

As accompanying drawing 4 to shown in the accompanying drawing 6, the utility model includes earphone socket 3, have many group storage tanks 31, cover plate 32, many group two point terminal plates 4, institutes such as oblique plate 41 constitute, the top that wherein has many group storage tanks 31 is provided with cover plate 32 sealings, be provided with many group two point terminal plates 4 at storage tank 31 places, each two point terminal plate 4 is respectively equipped with the relative tilt sheet 41 towards central authorities, after the earphone inserting column is inserted from the side, all form two contact points with each terminal plate 4, and two oblique plates 41 are to have inside elasticity, touch and can produce better urgent splice grafting, guarantee its conducting effect; Cover plate 32 is after terminal plate 4 is set, and involutory socket 3 forms closed, and it can utilize ultrasonic waves sticker or the firm combination of other any-modes, still can make terminal plate 4 can not produce shortcoming loosening or that come off.

Above-mentioned only is the utility model one preferred embodiment, as the structure change of part, for example terminal plate is designed to the contact point structure more than 2, also can obtain similar effect.

Claims

1, a kind of earphone socket contact point structure, include earphone socket (3), organize storage tank (31) more, sealed by a cover plate (32) on it, it is characterized in that: locate at storage tank (31), can be provided with many groups two point terminal plate (4), each two point terminal plate (4) is respectively equipped with the relative tilt sheet (41) towards central authorities, and cover plate (32) is after terminal plate (4) is set, involution socket (3) forms closed.
