Description

A kind of electric connector structure

Technical field

The utility model relates to a kind of electric connector structure, relates in particular to a kind of a kind of electric connector structure of assembling that man-hour is short, cost is low, it is firm to locate and can making the more stable quality of signal transmission.

background technology

At present, fast development along with computer science and technology, the kenel that makes computer develops into small volume, notebook computer easy to carry by desktop computer, and be prevalent in each corner in society, when user is when carrying out data signals transmission or be connected with other interface equipment, need so-called interface equipment, and general interface equipment on the market the most generally and widely popular use still using USB (USB) as main flow.

Moreover, along with notebook computer, the electronic installation designs such as ultra-thin notebook computer all trend towards light, thin, short, little, and in order to make electronic installation volume-diminished, electric connector on electronic installation internal circuit board needs small but excellent close, overall construction intensity also needs to strengthen thereupon, and because universal serial bus connector also upgrades to more high-order specification pattern (USB3.0) by early stage specification pattern (USB2.0), and promote its practical function and range of application, but because electric connector must meet the size standard of USB, its width and length are all fixing and cannot do to reduce, to avoid affecting whole structural strength because of hyoplastron dimension reduction, if hyoplastron dimension reduction, by causing terminal group easily to exit in the situation of hyoplastron or structural deterioration, occur.

For addressing the above problem, the electric connector structure of prior art as shown in Figure 9 and Figure 10, pedestal A1 inside on this insulating base frame A is provided with terminal groove A11, on terminal groove A11, be equipped with terminal group B, and cover and be positioned with a shield shell C in insulating base frame A outside, and the first shell C1 inside on shield shell C is formed with the grafting space C10 that can stretch into for the hyoplastron A2 on pedestal A1; With respect to the fitting portion A21 on the another side surface of terminal groove A11, second housing C2 is provided with the chimeric shield C21 that is fastened in hyoplastron A2, just second housing C2 can be covered in hyoplastron A2 outside, and be assembled to reduce the length dimension of shield shell C with the first shell C1, and promote structural strength whole after insulating base frame A length reduction.

But, the mode of this shield shell C assembling is first by the mutual chimeric fixing of the fitting portion A21 of the shield C21 of second housing C2 and hyoplastron A2, and make after hyoplastron A2 and pedestal A1 assembling, again hyoplastron A2 is pushed in the grafting space C10 of the first shell C1, the buckle C11 of the first shell C1 just can be held in second housing C2 and be positioned at the draw-in groove C23 on locating clamp plate C22, and the elastic fastening plate C24 of this locating clamp plate C22 is held in the upper corresponding catching groove C12 of the first shell C1, be combined into one, but cannot once complete assembling when the first shell C1 of this kind of shield shell C and second housing C2 assembling, need to separately carry out assembling more than secondary, increased assembling man-hour, also make cost significantly increase, and because must having certain thickness, the package assembly of the first shell C1 and second housing C2 could strengthen unitary construction, to cause whole thickness relatively to increase.

So, how to address the above problem, be the direction place of institute of the relevant manufacturer wish research improvement of being engaged in the industry.
