The utility model further defines, and said metal framework is fixed together through integrated mode and pedestal.
The utility model further defines, and said pedestal is provided with the some accepting holes that run through lower surface from upper surface, and conducting terminal is housed in the accepting hole.
The utility model further defines, and said sidewall potting is in pedestal and be enclosed to form some openings.
The utility model further defines, and said opening is corresponding one by one with accepting hole.
The utility model further defines, and the size in said hole is less than 0.5mm.
The utility model further defines, said conducting terminal comprise base portion, from base portion upwardly extendingly go up elastic portion, from base portion to the following elastic portion that extends below and from the upwardly extending holding parts of base portion.
The utility model further defines, and the said end of going up elastic portion is provided with contact site, and the end of following elastic portion is provided with down contact site, and holding parts is provided with hangnail.
The utility model further defines, and the position in the hole on the said metal framework is lower than the position of the hangnail of conducting terminal.
The utility model further defines, and said upward contact site extends the upper surface of pedestal, and following contact site extends the lower surface of pedestal, hangnail and pedestal fixing.
Compared to prior art; The metal framework of the utility model electric connector is provided with the hole, with the integrated process of pedestal in, plastic cement flows and to pass the hole and form reference column; Metal framework and pedestal are fixedly positioning, strengthen the retention effect of metal framework and pedestal when reaching electromagnetic shielding.
