CN203466325U - Jack provided with assembly-deformation-prevention elastic sheet - Google Patents

Abstract

The utility model discloses a jack provided with assembly-deformation-prevention elastic sheets. The jack comprises a rubber core and elastic sheets. The rubber core is provided with a circular jack, and is provided with a plurality of insertion grooves matched with the elastic sheets; the elastic sheets are inserted into the insertion grooves and are fixed with the rubber core into a whole; each elastic sheet comprises a base sheet and a contact; the base sheet and the contact are of an integral structure, and are combined into an L shape; a bended position each elastic sheet is in an arc shape; a matching joint of each base plate and each contact extends out to form a protruding ejection sheet; and each ejection sheet is higher than each contact. The jack provided by the utility model has the advantages of simple structure and reasonable design, makes the ejecting pressure is vertically applied to the base sheet in assembly through the ejection sheet, and can avoid the effects on the insertion and extraction force and working stability when the jack is matched with a plug caused by the integral deformation of the elastic sheets due to the ejecting pressure in assembly.

Description

Jack with anti-assembly deflections shell fragment

Technical field

The utility model relates to a kind of audio frequency terminal, specifically a kind of for transmission of audio signal the jack with anti-assembly deflections shell fragment.

Background technology

Jack is widely used, and all has application in each electron-like, digital product, simultaneously in the middle of automobile, because the needs of audio frequency input, output are also usually applied to jack.

How existing jack, be comprised of glue core, shell fragment two parts, and shell fragment inserts in glue core, is fixed as one with glue core.Existing shell fragment is generally L-shaped, and its bending place is curved, as shown in Figure 1, in the assembling process of actual jack, need to pass through jack unit, and glue core is compressed into in L shaped shell fragment top, and shell fragment is stuck in glue core, realizes integrated assembling.In the process of pressing on top, the knuckle place of L shaped shell fragment is subject to the effect of downforce, and the angle on L shaped shell fragment both sides is increased, and the downforce that makes to have assembled the shell fragment of rear jack reduces, when affecting jack contact engaging and separating force, also affect it contacts the electrical conveying while coordinating stability with plug.

Utility model content

The purpose of this utility model is to provide a kind of elastic piece structure that can increase to change, and makes the shell fragment of jack prevent deformation in assembling.

For achieving the above object, the technical scheme that the utility model adopts is:

With a jack for anti-assembly deflections shell fragment, include glue core, shell fragment.

Described glue core is with circular socket holes;

Which is provided with slot a plurality of and that shell fragment is suitable;

Described shell fragment inserts in described slot and is fixed as one with glue core;

Described shell fragment is made by conductive material;

As a kind of preferred, described shell fragment is made of metal;

Described shell fragment includes substrate, contact;

Substrate and contact are integral type structure, and it combines L-shaped between the two;

The bending part of described shell fragment is curved;

Described synapsis is provided with the contact of outwardly convex;

On described substrate, be also provided with the boss coordinating with described slot;

Described substrate tail end also has a pin to connect;

Described substrate extends the top flat of a projection at the place of being connected with contact;

Described top flat is higher than contact.

The utility model is simple in structure, reasonable in design, pressure on top surface while making to assemble by top flat only vertically is used on substrate, the contact engaging and separating force in the time of can avoiding when assembling effect because of pressure on top surface to cause the bulk deformation of shell fragment to coordinate with plug jack and the impact of job stability.

Accompanying drawing explanation

Fig. 1 is the structural representation of this traditional shell fragment.

Fig. 2 is structural representation of the present utility model.

Fig. 3 is elastic piece structure schematic diagram of the present utility model.

In figure, each label is respectively:

(1) glue core; (2) shell fragment; (3) contact; (4) substrate; (5) top flat.

Embodiment

For convenience of the utility model is done, further understand, existing in conjunction with Fig. 2, Fig. 3 for an embodiment, the utility model is further illustrated.

Embodiment:

In Fig. 1 and Fig. 2, the utility model includes glue core 1, shell fragment 2, and described glue core 1 is with circular socket holes; Which is provided with slot a plurality of and that shell fragment 2 is suitable; Described shell fragment 2 inserts in described slot and is fixed as one with glue core 1; Described shell fragment 2 is made by conductive material; Described shell fragment 2 is made by metallic copper; Described shell fragment 2 includes substrate 4, contact 3; Substrate 4 is integral type structure with contact 3, and it combines L-shaped between the two; The bending part of described shell fragment 2 is curved; Described synapsis 3 is provided with the contact of outwardly convex; Described substrate 4 is extending the top flat 5 of a projection with the place of being connected of contact 3; Described top flat 5 is higher than contact 3.

The above, only better enforcement of the present utility model, not the utility model is done to any pro forma restriction, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the equivalent embodiment of equivalent variations, at this, all the technical solution of the utility model contents that do not depart from, any simple modification, equivalent variations and the modification just according to technical spirit of the present utility model, above embodiment done, all still belong in the scope of technical solution of the present invention.

Claims (2)
