Abstract
An electrical connector (1) comprises an insulative housing (10) defining a receiving cavity (18), a plurality of terminals (20) retained in the housing, and at least one ground bus module (30) received in the receiving cavity. Each ground bus module includes an insulative body (32) having a depressed inner surface in which the ground buses are integrally molded, and an opposite outer surface on which the mating beams of the terminals are positioned to be as close to corresponding terminals as possible to provide effective ground reference.
Claims4
An electrical connector for being mounted on a circuit board, comprising:
- an insulative housing defining a receiving cavity and a plurality of passageways communicating with the receiving cavity;
- a plurality of ground bus modules being received in the receiving cavity and each including an insulative body, a plurality of ground buses integrally embedded in one side of the insulative body for mating with corresponding grounding members of the complementary connector;
- and
- a plurality of signal terminals each having a retaining portion retained in a corresponding passageway, a mating portion projecting from one end of the retaining portion for mating with a corresponding contact of the complementary connector, and a soldering portion extending from another end of the retaining portion for being soldered to the circuit board, the mating portions of the signal terminals positioned on another side of the insulative body of the ground bus module and opposite to the ground buses;
- wherein
- the bottom wall of the housing defines a pair of slots in a top face at opposite sides thereof;
- wherein
- the insulative body of each ground bus module forms a plurality of positioning ribs extending from the upper edge of the outer surface thereof, a channel is defined between every two adjacent positioning ribs to receive a part of the mating beam of a corresponding signal terminal;
- wherein
- each ground bus of the ground bus module has a plate-like body, a pair of retaining legs and a soldering tail between the retaining legs, the retaining legs and the soldering tail both extending downward from a lower edge of the plate-like body;
- wherein
- the bottom wall of the housing further defines two rows of retaining holes beneath and communicating with the two rows of slots for receiving the retaining legs of the ground buses;
- wherein
- the bottom wall of the housing forms a row of positioning blocks in the receiving cavity for retaining the ground bus modules in position;
- wherein
- each ground bus defines several elongated notches in an outer surface thereof so as to be as close to corresponding signal terminals as possible.
