Description

The socket connector structure-improved

Affiliated technical field

The utility model relates to a kind of socket connector structure-improved, is meant a kind ofly by a support of replacing shell fragment especially, provides higher contact engaging and separating force, to help seizing on both sides by the arms the socket connector of banjo.

Background technology

The DC supply socket connector of tool charge function is widely used on the Mobile Communications product, and has become the indispensable part of each action mobile phone, and its major function is to provide the transmission of power supply; Along with the Mobile Communications product constantly develops towards frivolous small direction, supporting with it supply socket connector also must cooperate with it constantly towards miniaturization, and is quite frequent because of the access times of socket connector, therefore whether has the good holding function.

Existing supply socket connector, it has generally included and has accommodated a columniform center terminal and a contact terminal in an insulating body, the insulating body; As shown in Figure 1, this contact terminal 50 is made up of a roof 51 and two side 53; Be provided with a contact flat spring 52 that upwards bends on roof 51, contact flat spring 52 is contained in the jack of insulating body; The two side 53 of contact terminal 50 is provided with card rib 54, contact terminal 50 is engaged in the draw-in groove of insulating body, also is provided with leg 55 on the two side 53 of this contact terminal 50, and it is welded on the circuit board with turning circuit.

Existing supply socket connector, its defective is, miniaturization along with the supply socket connector, its each assembly also dwindles thereupon, in the butt connector plug is inserted into the insulating body jack, when contacting with center terminal and contact terminal, the contact flat spring 52 of contact terminal contacts the area of interfering with the butt connector plug too small, can not produce higher contact engaging and separating force, make the butt connector plug easily in jack, come off, cause electrically bad; Simultaneously, in existing supply socket connector, it only relies on the card rib 54 on the contact terminal two side 53 to engage with draw-in groove on the insulating body, with fixing contact terminal 50, but when contact terminal 50 with after the butt connector plug repeatedly docks plug, easily cause the loosening of contact terminal 50, and contact flat spring 52 is easy to generate distortion under stressed situation, causes whole contact engaging and separating force to reduce, be difficult for the plug of butt connector, therefore above-mentioned technology still need be improved.

Summary of the invention

Main purpose of the present utility model is to provide a kind of supply socket connector improvement structure, it is by the shell fragment of replacing of replacing the newly-increased reflexed of end wall at contact terminal, in order to support contact terminal, make contact terminal produce the reaction force that makes progress of an increase, contact engaging and separating force just, interfere the butt connector plug, make its difficult drop-off, thereby produce good circuit turn-on.

Another purpose of the present utility model is to provide a kind of supply socket connector improvement structure, the dual-side of replacing end wall of its contact terminal is provided with two bending pin, tip upside down in two grooves of insulating body rear wall, in order to fixing contact terminal, make terminal when contact is stressed, be difficult for deforming the contact engaging and separating force when contacting interference with butt connector with increase.

For reaching above-mentioned purpose of the present utility model, can be realized by following technical proposals: supply socket connector improvement structure of the present utility model, it comprises an insulating body, one is contained in a cylindrical center terminal and the contact terminal in the insulating body; Wherein be provided with jack that is provided with for center terminal and the ccontaining inside groove that is provided with for contact terminal in this insulating body, this ccontaining inside groove is that the bottom from insulating body inwardly concaves, and connect with jack, on the rear wall of ccontaining inside groove, then be provided with two grooves, replace the bending of two on end wall pin with contact terminal respectively and engage, be installed in the insulating body with the  contact terminal; This cylindrical center terminal, its front end is provided with and is connected in terminal body, and forms suitably flexible two contact chips, and the rear end then vertically extends a weld tabs, closes on the end and is provided with two oblique shape grabs vis-a-vis; This contact terminal is by a roof, replace end wall and two side walls is formed; The roof of contact terminal upwards is bent to form a contact flat spring, and contact flat spring is contained in the ccontaining inside groove of insulating body; The mid portion reflexed of replacing end wall of contact terminal extends, and forms one and replaces shell fragment, in order to support the contact flat spring on the roof; The dual-side of replacing end wall then forms two bending pin, is fastened in two grooves of insulating body rear wall, in order to fixing contact terminal, makes and replaces shell fragment and obtain support; Also be provided with leg on the two side walls of contact terminal, it is welded on the circuit board, with turning circuit.

When the butt connector plug inserts, contact flat spring on the contact terminal is in contact with it, contact flat spring is because of downward displacement of stressed generation, replacing the shell fragment of replacing that end wall upwards is bent to form with contact terminal contacts, it is stressed because of press contacts under the contact terminal to replace shell fragment, produce a reaction force that makes progress, support contact terminal, and stop contact terminal further to bottom offset, the relative contact terminal that makes will produce the reaction force that makes progress of an increase, and contact engaging and separating force just is in order to interference butt connector plug, thereby make it be unlikely in the jack of insulating body, to come off, help the excellent electrical property conducting; Replace two bending pin of the dual-side formation of end wall at contact terminal, it tips upside down on insulating body and replaces in two grooves of end wall, reinforce contact terminal, after making contact terminal and the butt connector plug repeatedly docking plug, contact terminal still can compare firmly, contact flat spring still can provide higher contact engaging and separating force after stressed repeatedly contacting, and helps the plug of butt connector.

For the personnel that utility model purpose of the present utility model and architectural feature can further be allowed be familiar with this technology understand, cooperate now appended graphic, with a concrete case study on implementation to the utility model further instruction.
