Description

Electric connector

Technical field

The utility model relates to a kind of electric connector, relates in particular to the electric connector that a kind of overall structure is stable.

Background technology

At present, general electric connector is used in coupling assembling and the accessory thereof on electric signal and power supply, its major function is to provide the bridge joint between various electronic installations and guarantees that signal can transmit accurately, and electric connector is due to application, frequency, power is different from applied environment etc., the type just with various forms and structure, and can be applicable to computer, computer interface equipment or industrial equipment, telecommunications and communication, automobile, transportation, household electrical appliance, medical or similar products, also be that in the middle of electronic installation, circuit is realized the indispensable parts of predetermined function.

Moreover, traditional electric connector is (as board to board connector, the connector of wire pair board connector or other type) conventionally can utilize a Male end connector and a terminative connector to coordinate docking, and the plug of Male end connector is butted up against in the socket of terminative connector, signal or power supply can be sent in control circuit by circuit board, but because Male end connector and terminative connector can be different for the seat body structure of terminal group location, so when Male end connector and terminative connector design, just how whether Design and manufacture cost is comparatively cheap to need to consider base structure, also need shape and the structure of abutting end subgroup and other spare part to design, just can make connector workmanship, production cost and structural stability are effectively controlled.

In addition, along with intelligent mobile phone now, the electronic installation popularization degrees such as flat computer promote, make online approach expand running gear to from computer, and make running gear application service fast-developing, community for example, real-time communication, reading and game etc., wherein the flat computer expansion foundation of also can arranging in pairs or groups is used, make flat computer just like notebook computer pattern, carry out keyboard input by expansion foundation, multi-point touch, power supply supply, the function such as port and calculating punch, have more the effect of extendibility and practicality, and generally expansion foundation side edge big city is provided with rotating shaft, and be provided with connector and plural trip in the ㄩ of rotating shaft shaped recesses inside, when flat computer is wanted to be connected with expansion foundation, flat computer side edge can be embedded in the groove of rotating shaft, and the connector of flat computer and the connector of expansion foundation are docked, and each trip is held in respectively in position, trip hole corresponding on flat computer, can by the rotating shaft of expansion foundation, make flat computer overturn as predetermined angular, with person easy to use, adjust the angle of watching or carry out touch control operation, also can fast flat computer and expansion foundation be formed separated by the trip switch of pulling in rotating shaft.

Yet, when the connector of flat computer is when connector in expansion foundation rotating shaft docks, its male seat just can mutually support and contact with the terminal group of female seat, just can the circuit board of flat computer and expansion foundation inside be formed and is electrically connected by terminal group, signal or power supply can be sent in control circuit by circuit board, but because male seat and the female seat of connector is mostly fixed structure, the plural terminals groove that terminal group is combined closely respectively in male seat or female seat, when the larger shock of flat computer is born in the rotating shaft of expansion foundation, just can cause male seat and the damage on master base structure or the destruction of connector, integrally-built less stable, also may make the trip in rotating shaft produce distortion, the situation that causes flat computer to form blocking and cannot extract occurs, in addition, when rotary movement repeatedly of flat computer is born in the rotating shaft of expansion foundation, also can make suitable strain for terminal group because there is no enough spaces in male seat and female seat, very easily make to produce between terminal group poor electrical contact phenomenon, or even terminal group excessive deformation or structural deterioration and have influence on the stability of whole signal transmission.

Summary of the invention

In view of the defect of above-mentioned electric connector, the purpose of this utility model is: design the electric connector that a kind of overall structure is stable.

Technical solution of the present utility model is: a kind of electric connector, comprise pedestal, link subgroup and fastening convex side, described pedestal comprises a pedestal, and in base bottom, be provided with plural number and place passage, and place and in passage, be positioned with link base portion that subgroup has, and in base portion one side place, bend downwards to extend and be provided with at least one variant part, by variant part place, bend outwardly and be extended with conductive part again, and be positioned on pedestal, place passage both sides places and be respectively equipped with fixed part, and be all upwards concaved with perforation in fixed part bottom, and on fixed part, be formed with the joint surface being communicated in perforation, on fixed part, be positioned with again the fastening convex side with the first connecting portion, and extend and be provided with the support division being relatively held on joint surface by the first connecting portion two ends bending.

Further, on the body of described pedestal, be positioned at place passage two side walls place be longitudinally provided with profile groove and guiding conduit, and in profile groove, be positioned with the base portion of link subgroup, and the variant part side edge of link subgroup is formed with and is positioned at the projection that supports that guiding conduit is done length travel.

Further, the base portion of described link subgroup is provided with the protruding thorn being positioned in profile groove.

Further, on the body of described pedestal, be positioned at and place the stop part that passage lower opening internal face place is formed with inside turnover, and the conductive part of link subgroup is provided with contact-making surface, and by contact-making surface place, is bent outwardly to extend to be provided with and be held in the end that supports that forms block location on stop part.

Further, the variant part of described link subgroup is extended with the first turning point adjacent to the downward reflexed in base portion place, and be extended with the second turning point by the first downward reflexed in end, turning point, reflexed goes out to have the 3rd turning point downwards again, the variant part of described link subgroup extends the conductive part with contact-making surface by the 3rd turning point, and by contact-making surface, is bent outwardly to extend to be provided with and support end.

Further, the first turning point of described variant part, the second turning point and place, inner side, the 3rd turning point are for being formed with elastic space.

Further, each place, variant part inner side of described conducting end subgroup is formed with elastic space.

Compared with prior art, the beneficial effects of the utility model are: the fastening convex side support division that can locate by fixed part is fastened on the buckling parts of reference column and forms lock-out state, and each variant part multistage bending structure design of link subgroup, elastic displacement stroke in the time of can increasing its docking, and enough forward contact forces are provided and can produce excessive deformation or structural deterioration, to guarantee repeatedly to plug the effect in electrical contact of docking; Can also by supporting projection, be positioned at guiding and the position-limiting action of the length travel of guiding conduit, be difficult for producing skew or rocking while making the displacement of link subgroup, overall structure is more stable.
