Description
Technical field
The invention belongs to technical field of electronic device, are related to a kind of improvement structure of electric connector, espespecially in insulating base frame
Portion has been assembled terminal group, and the terminal base that ejection formation two is oppositely arranged is embedded on each group of terminal, such terminal base
Common mode design can save mold tricks, and make two groups of abutting end stromas formed be arranged side by side and number of terminals is then single group terminal base
Two times of number of terminals.
Background technique
Electronics technology is fast-developing now, make the speed of the operations such as computer, server be getting faster and performance increasingly
It is good, and in computer or server internal in addition to including central processing unit on mainboard and memory as information processing maincenter
Except, the interface equipments such as various screens, modem be also the electronic devices such as computer, server carry out picture show,
The emphasis of data transmission and instruction control can install various forms of adapters additional using the slot on mainboard, set interface
It is standby to be used by carrying out transmission data between adapter and electronic device and as purposes is expanded.
Furthermore as electronic device is widely applied, for adapters such as periphery expansion board, display adapter, memories
The requirement that mass data transmits with speed increasingly improves, and the bus transfer framework of early stage extended interface has not used, and in order to
It solves the problems, such as that conventional adaptation cassette tape is wide insufficient, just there is technical staff to develop the adaptation card architecture of a variety of different size standards,
To adapt to the development trend of current electronic device, and general connector would generally be cooperated using the slot of pedestal with adapter
Docking, and the terminal group in slot is supported to the multiple contacts being contacted on adapter card edge and is electrically connected, it can will believe
Number or power supply be sent in control circuit by circuit board to execute corresponding operation function, but connector is in addition to design at present
It is also higher and higher for transmission speed and bandwidth requirement increasingly except microminiaturization, by contrast produced by high frequency signal transmission
The problem of be even more emerge one after another, and with the number of terminal group increase and be distributed it is also more intensive, it is extremely easy because between terminals of adjacent
It gets too close to and electromagnetism when high frequency signal transmission is caused to involve cross-talk etc., future can also be grown up with faster speed, make to connect
The signal interference problem for connecing device itself will be more serious.
And it includes that insulating body, multiple in the terminal group being installed on inside insulating body connect that conventional highfrequency connector, which is,
Ground terminal, and the ground strip that ground terminal can be serially connected, wherein in terminal group using embedment project integrally formed with
Terminal base, and terminal base is installed on inside insulating body together with terminal group, though assembly program can be simplified, avoid terminals of adjacent
Between be easy to have led to the problem of contact short circuit because of assembly error, but because quantity is arranged in the terminal in insulating body difference slot
Understand difference, needs the terminal pedestal toilet molded individually on each group of terminal raw using two molds and different technique
It produces, causes whole manufacturing cost that can not be effectively reduced, and in view of the number of terminals of terminal base, mold use tricks and production
Cost, and shape and structure that cooperation is assembled in insulating body make just to need in terminal base modularized design more careful
With it is careful, and terminal base collocation terminal group how properly to be configured in the limited space of insulating body, also will be influence connection
The key point that can cost reduce, overall structure is more stable in the modular design of device, then need those skilled in the art
It redesigns effectively to be solved.
Summary of the invention
Inventor collects related data via multi-party assessment and consideration in view of the above problem and missing, and using from
Thing is constantly tested and is modified in many years research and development experience of the industry, proposes a kind of electrical connection for being able to solve above-mentioned technical problem
The improvement structure of device.
To include grafting space inside the docking section that it is a primary object of the present invention to insulating base frames at pedestal side,
And it is respectively equipped with accommodation groove of the mounting portion at positioning body two sides at the slot that the another side of pedestal corresponds in grafting space, and
