In the electronic product, widely-used pcb board is done the immobilizing foundation of electronic component.The some of them parts need be connected with external circuit receiving and sending messages, and when task is finished or shut down, and need to remove to connect. and audio earphone just belongs to the jockey that this need repeatedly plug.
In the practical application, audio headset receptacle connector and plug are used.At present, the socket position of audio socket connector body front end, all establish a becket, this becket comprises the dome platform on its excircle direction, manufacturer's general mode of embedding and injection molding that adopts in manufacture process is one-body molded this becket and plastic body, its dome platform structure also strengthens itself and the fastness that engages of main body, establishing a U-shaped ground strip near the position of inserting mouth in addition, the middle part of this U-shaped ground strip comprises a contact site, this contact site contacts with becket by a groove on the main body, and contact site adopts 0.3mm thickness more.The bar groove of prior art and the outer circumference surface of becket are tangent, be that contact site is that line contacts with becket, if during the not high or material expanded by heating of the accuracy of manufacture, contact site and becket be loose contact, cause becket effectively ground connection to reach the function of antistatic or electrostatic screen.
[utility model content]
Contact insufficient, the special technical problem that easily produces loose contact with contact site in order to solve existing becket, the utility model proposes a kind of contact site that allows and contact, can guarantee the compression type precision-fit type audio socket connector of this audio socket connector good anti-static or electrostatic screen function steadily in the long term with becket interference fit, compression type.
The technical scheme that deficiency adopted that the utility model solves the prior art problem is: a kind of compression type precision-fit type audio socket connector is provided, comprises connector body and structural member; Described main body comprises socket, grafting chamber and neck therebetween; Described socket comprises a becket, is provided with a groove along first outer circumference surface of described becket the inner; Described structural member comprises the U-shaped ground strip that cooperates with described neck, and the middle part of described U-shaped ground strip is provided with a contact site, and described contact site is embedded in described the groove that is mated and with described becket and contacts; Increase the intersecting area of described groove and described first outer circumference surface.
The further improvement of the utility model audio socket connector is: increase the groove width of described groove, the thickness of the increase described contact site corresponding with it.
The further improvement of the utility model audio socket connector is: described groove groove width is greater than 0.5mm.
The further improvement of the utility model audio socket connector is: described contact site is provided with projection.
The further improvement of the utility model audio socket connector is: the height of described projection can be 0.05mm～0.15mm.
The further improvement of the utility model audio socket connector is: the height of described projection is 0.1mm.
The further improvement of the utility model audio socket connector is: described contact site comprises the V-type opening, and described V-type opening is divided into a plurality of osculating elements with described contact site.
The further improvement of the utility model audio socket connector is: the end of described osculating element is provided with the contact, and this contact can contact with the first evagination round platform of becket the inner.
The further improvement of the utility model audio socket connector is: the transverse plane of described osculating element favours its circular planes that contacts.
Compared to prior art, the beneficial effect of the utility model audio socket connector is: adopt the intersecting area that increases bar groove and becket, in fact increased the exposed region of contact site and becket contact position, the exposed position of contact site and becket interference fit, this contact-making surface is more firm, in addition, on contact site, set up projection, also guaranteed the reliability that contact site contacts with becket.Obviously, this audio socket connector good anti-static or electrostatic screen function have been guaranteed in this reliable compression type contact
