The terminal connector of convergence ground connection formula
Technical field
The utility model relates to a kind of line connector, relates in particular to a kind of terminal connector of convergence ground connection formula.
Background technology
Generally be applied to the terminal board connector of electric signal transmission, as Figure 11, shown in Figure 12, comprise: a plastic cement body 91, be equipped with 911: two rows of two row's terminal board accommodation apertures terminal board 92 side by side, be embedded at accordingly respectively in the terminal board accommodation aperture 911 of this plastic cement body 91; One shield shell 93 is coated on outside this plastic cement body 91.Because above-mentioned terminal board connector, can stop, exclude of the interference of external electromagnetic ripple though be provided with shield shell 93 to each terminal board 92, yet be listed in spacing convergence very in the plastic cement body 91 owing to be installed on each terminal board 92 in the connector, when each terminal board 92 carries out the signal transmission, often interfere with the signal transmission of other terminal board 92 because of the electromagnetic wave that is produced.For solving this problem, at present, people are on the plate face of this shield shell 93, depressed part 931 is arranged as Figure 11, shown in Figure 12 to lower recess, by each each terminal board 92 of depressed part 931 convergences, the electromagnetic wave that each terminal board 92 is produced can be received, cut ripple and ground connection by this depressed part 931 nearby, reaches the purpose that reduces each terminal board phase mutual interference.
But in the above-mentioned structure, because each depressed part 931 is the 93 direct punch formings of self-shileding housing, because cold draw has limitation, and limited the degree of depth that this depressed part 931 is caved in, promptly this depressed part 931 also can't very level off to a side of each terminal board 92.Therefore, the electromagnetic wave that each terminal board 92 is produced still has the possibility of not intercepted and captured by depressed part 931, and 92 of each terminal boards still have the phenomenon of phase mutual interference to take place.In addition, because being subject to shield shell 93 is the very little metal shell of a volume, only depressed part 931 can be set in the position of part, therefore, only can cut ripple ground connection to depressed part 931 pairing adjacent terminal rows 92, the effect of impedance phase mutual interference, and can't all cut ripple ground connection to all terminal boards 92, therefore its ground connection effect is unsatisfactory, and improved necessity is arranged.
