Description

Electric connector structure

Technical field

The utility model relates to a kind of electric connector structure, relates in particular to a kind of stability that can guarantee signal transmission, operate simple and easy, assemble firm electric connector structure.

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
