Description

The Earphone joint structure

Technical field

The utility model relates to a kind of Earphone joint structure, particularly a kind of Earphone joint structure easy to assembly.

Background technology

Progress along with science and technology, but the electronic goods of various sounding all disposes Earphone joint, for example broadcast receiver, walkman, computer or the like, provide headset plug to plant by Earphone joint, sound is converted to the kenel of earphone sounding from the kenel of sound horn, therefore Earphone joint just becomes now indispensable assembly in the electronic goods, and the structure of Earphone joint is various, and structure is had nothing in common with each other.But how developing a kind of Earphone joint easy to assembly, but is one of at present important problem, also is goal of the invention of the present utility model.

As shown in Figure 1, exploded view for present known headsets joint, can know on scheme and find out, this Earphone joint is mainly assembled by a body 11 and a plurality of end pin 12, wherein this body 11 axially forms a jack 111, and form the slot 112 of a plurality of vertical jacks 111 in its all side, and the outside cell wall of slot 112 offers a concane gap 113; End pin 12 presents irregular lamellar body, and the side edge bending forming has a block holding part 121 in the central, and end pin 12 1 end bending formings have a connecting portion 122, this end pin 12 is inserted in the slot 112 of this body 11, and this connecting portion 122 exposes outside this slot 112, electrically connect for his thing, and this block holding part 121 fastens in this concane gap 113, make end pin 12 location, thereby finish the assembling of Earphone joint.But there is following defective in this existing Earphone joint when actual assembled:

For end pin 12 can be inserted in the slot 112 of body 11 smoothly, its connecting portion 122 is straight no bending before plant, and etc. after end pin 12 is plugged on the slot 112 of body 11, carry out bending machining to exposing slot 112 outer connecting portions 122 again, so existing Earphone joint assembling mode not only can increase the step of assembling, and because more and more miniaturization of Earphone joint electronic goods production, make bending machining be difficult for carrying out, thereby cause the damage of connecting portion 122, and then reduce its product percent of pass.

In sum, existing Earphone joint has necessity of further improvement.

The utility model content

The main technical problems to be solved in the utility model provides a kind of Earphone joint structure, to simplify number of assembling steps, to improve product percent of pass.

For solving the problems of the technologies described above, the utility model provides a kind of Earphone joint structure, mainly closing a plurality of end pin by a body is assembled, wherein body shaft is to forming a jack, and all sides of body have a plurality of draw-in grooves, and each draw-in groove is separated by track regions, and these track two ends are open shape; A plurality of end pin, its nearly centre has a block holding part that protrudes the surface, and end pin one end bending forming has a connecting portion, the end pin is inserted in the track of body, and its block holding part fastens the draw-in groove in body, and its connecting portion exposes outside the track, therefore, the utility model directly will hold pin to be plugged on the track of body can finish assembling, thereby reaches the purpose of simplifying number of assembling steps, improving product percent of pass.

Embodiment

Below in conjunction with accompanying drawing a preferred embodiment of the present utility model is described in detail to set forth the utility model institute employing technology, means and effect.

As shown in Figure 2, a kind of Earphone joint structure provided by the utility model, it is mainly assembled by a body 20 and a plurality of end pin 30, wherein:

Body 20, it axially forms a jack 21, and body 20 all sides have a plurality of draw-in grooves 22, and each draw-in groove 22 separated by track 23, and these track 23 two ends are open shape; And each draw-in groove 22 is axially-aligned, and the vertical jack 21 of the notch direction of each draw-in groove 22.

A plurality of end pin 30, it has a block holding part 31 that protrudes the surface near centre, and the 30 1 end brake formings of end pin have a connecting portion 32, and connecting portion 32 and block holding part 31 by different towards, end pin 30 is planted and is positioned the track 23 of body 20, and block holding part 31 fastens the draw-in groove 22 in body 20, and its connecting portion 32 exposes outside the track 23.

When end pin of the present utility model 30 during with body 20 assemblings, end pin 30 can directly be planted and be positioned two and be on the track 23 of open shape, and makes the block holding part 31 of end pin 30 fasten draw-in groove 22 in body 20, thereby finishes the assembling of Earphone joint.In other words, the moulding of can prebending of the connecting portion 32 of this end pin 30 is assembled again, and the moulding of connecting portion 32 can moulding in the lump when end pin 30 punching out, thereby has avoided needing the bending machining that hold pin 30 connecting portions 32 on small day by day body 20 after end pin 30 and body 20 assemblings.Therefore the utility model can be simplified number of assembling steps, improve the Earphone joint product percent of pass.

This preferred embodiment and respective drawings are not to be used for limiting the scope that the utility model is implemented, i.e. all equivalent variations of being done by the utility model claim scope are all in the utility model patent application protection range.
