Specific embodiment

Further illustrate a specific embodiment of the invention with reference to the accompanying drawing.

In conjunction with Fig. 1, Fig. 2 and Fig. 4, high speed transmission of signals connector body provided by the invention, including port, the receipts of port At least two pairs of conductive terminals 2 are equipped in cavity 1.Each pair of conductive terminal 2 is separated from each other arrangement.In connector body of the invention Two conductive terminals 2 of same centering are a pair of of differential signal line, and each pair of conductive terminal 2 is separated from each other arrangement, so that any two The distance between differential signal line is increased, thus reduce the mutual signal interference of any two pairs of differential signal lines, so as to Enough improve connector body in insertion loss (in conjunction with Fig. 6 and Fig. 7), reflection loss (in conjunction with Fig. 8 and Fig. 9), crosstalk (in conjunction with Figure 10 And Figure 11) etc. the problem of, so as to improve the transmission rate of signal transmission connector.

Specifically, the shortest distance between any two pairs of conductive terminals 2 is led than two in same a pair of of conductive terminal 2 The shortest distance between electric terminal 2 is big.
