Description

Electric connector

The utility model relates to a kind of electric connector, and is especially a kind of at the electric connector that in a row is provided with masking device between terminal.

The fast development of electronics technology has driven the quick circulation of information, and the electric connector of wherein undertaking telecommunication transmission important task has also produced various design because of the difference of connection object.But, the electric connector of which kind of type no matter, whether its telecommunication transmission is effectively stable, and whether to be subjected to electromagnetic interference relevant with its terminal.Electromagnetic interference can be divided into two classes, one for extraneous for the interference that electric connector terminal produced, another between the electric connector internal terminal because crosstalking of being produced in the transmission course, this crosstalk phenomenon is provided with density at terminal and heals and take place more easily when big.Especially, current scientific and technological progress is quick, the trend toward miniaturization of electronic component becomes clear day by day, it no matter is type computer also or on the various portable computer on the table, the electric connector of high density of terminals is used more and more extensive, therefore the terminal pitch of electric connector inside is added the high-frequency signals that is adopted fast in order to pursue from very little usually, make between terminal crosstalk because of high-frequency transmission caused particularly evident.Such as United States Patent (USP) the 5th, 697, No. 799 disclosed electric connector designs, the electromagnetic interference that outer bound pair electric connector is produced is only considered in the design of this electric connector, and do not consider high-frequency crosstalk between each terminal, crosstalk at signal between terminal and to cause easily under the stability and validity condition of poor of signal transmission, designing the electric connector that signal is crosstalked between a kind of maskable terminal is the task of top priority.

Main purpose of the present utility model is to provide a kind of electric connector with comprehensive shield effectiveness of the combination of inner and outside, the electromagnetic crosstalk that this electric connector can avoid terminal to be produced when carrying out the high-frequency signals transmission, the stable transfer of assurance signal and high-quality, and improve its validity.

The purpose of this utility model is achieved in that and is provided with masking device on electric connector; this masking device comprises shadowing elements and shell; wherein shadowing elements is located in the groove of insulating body pedestal; shell then covers and is overlying on the insulating body outer wall; suitable position at shadowing elements is provided with junction; and this junction is done being connected of different angles with shadowing elements; and can be connected with the earthed circuit of circuit board; the noise of crosstalking that in shadowing elements receives by terminal transmission signal process, is produced; can see through its junction noise ground connection of will crosstalking; and then the influence of protecting terminal that it is not crosstalked when transmission signal; guaranteeing the stable transfer of signal, and reach the effect of comprehensive ELECTROMAGNETIC OBSCURANT.

Advantage of the present utility model is, electric connector shields a considerable amount of terminals simultaneously with solid memder, solve the cross-interference issue between each terminal effectively, the stability and the validity of high-frequency transmission signal have been improved, and the comprehensive shield effectiveness of the combination of inner and outside is provided, thereby can have produced the more transfer function of high-quality and efficient.
