The utility model is meant the firm inlay card structural design applicable to connector male and female seat especially about a kind of improvement of connector structure.

Background technology

Along with the development of enhancement day by day of science and technology, the electronic goods that is sold on the market at present is invariably towards miniaturization and sophistication or ultra-thin evolution; And the utility model is improved, promptly be in the electronic goods such as present mobile computer NB, personal digital assistant PDA, mobile phone, when screen is connected with the main frame winding displacement, the connector construction that must use, can generally divide on this connector members the male and female seat is arranged, the two winding displacement ends that desire can be connected are connected with the male and female seat respectively earlier, see through the male and female seat of connector again, plug connection; It should be noted that the connector that present industrial circle is developed, its specification volume can be made into quite frivolous, but has the considerable kenel of numbers of terminals; In other words, the measure of precision of connector male and female seat must be quite high, to guarantee that each terminal is connected reliably;

And the utility model will be inquired into, promptly be connector male and female seat connect plug after, connection firm problem;

The strength of connection of connector, quite important at aforesaid electronic goods in the use, for example: the experience that runs into through regular meeting is, and this electronic goods is after use after a while, and the video signal regular meeting on the screen has the situation of bar wire noise or color variation to produce; Trace it to its cause, usually problem occurs in the connector that screen is connected with the main frame winding displacement and takes place to become flexible, and causes the screen video signal bad, and especially the winding displacement of lifting type screen is the easiest influences video signal because of causing connector to get loose after repeatedly pullling; Additional disclosure be, it plugs the outside that is nested with mutually connector male and female seat, normally made with sheet metal, can see through this sheet metal formation and cover negative pole GROUND PIN or ground strip, and its tight exposure level that covers negative pole of connector male and female seat can influence the stability of video signal;

Therefore, the industrial circle research and development see through direct stamping technology moulding usually for moulding block tongue 111 structures on connector 10 female seats 11, after male and

female seat

12,11 plugs combination, can offset with male seat 12 end faces 121 through this block tongue 111 and close as shown in Figure 5, and increase the fluid-tight engagement degree that male and

female seat

12,11 covers negative pole by this; Yet quite limited through the actual elastic force that uses the back to find this block tongue 111 of industrial circle, after connector 10 male and

female seats

12,11 were inserted knot mutually, connector 10 gets loose, and to improve and cover the tightness degree that negative pole contacts quite limited;
