High frequency electrical connector

摘要

An electrical connector includes an insulative housing having a reception surface for receiving a complementary connector, an engaging surface opposite the reception surface for connecting with an external cable including a plurality of cable lines, and a plurality of receptacles formed in the insulative housing in communication with the reception surface and the engaging surface. A plurality of contacts are respectively received in the receptacles of the insulative housing and each contact has a reception portion for electrically engaging with the corresponding cable line of the cable. First and second shieldings secured together enclose the insulative housing and at least one end of the first and second shieldings is secured to a peripheral edge of the reception surface of the insulative housing. A positioning member is adapted to be received between the engaging surface of the insulative housing and the two shieldings to abut against the engaging surface of the insulative housing, wherein passageways are defined in the positioning member in communication with the receptacles and retain the cable lines therein. The positioning member prevents sputtered plastic particles from entering an interior of the insulative housing via the engaging surface during formation of a plastic shell which encloses the two shieldings.
