摘要:
An electrical connector (1) straddle-mounted on an edge (20) of a printed circuit board (2) includes an insulative housing (10) having an elongated groove (11) for mating. A support subassembly (3) is inserted from the opposing side of the housing (10) to expose its portions in the groove (11). The support subassembly (3) includes two bases (30) with attached signal conductors (5) and a U-shaped ground member (4). Two parallel-arranged side portions (40) of the U-shaped ground member (4) are integrally connected via its central portion and each of them is located parallel to a row of signal conductors (5) as their ground reference. The united ground member (4) can be used to establish ground path to the printed circuit board (2) by fewer contacting legs (42) sheared therefrom and help all parts of the support subassembly (3) to be installed in the connector housing (10) at one time.

An electrical connector assembly (1) includes a mother board (10), a card edge connector (20) mounted on the mother board, a daughter card (30), and a pair of board hold downs (40) mounted on the mother board. The card edge connector includes a housing (21) defining a slot (22), and a number of contacts (23) disposed on opposite sides of the slot and exposed into the slot. The daughter card includes a mating edge (31) inserted into the slot of the housing, a number of conductive pads (33) on the mating edge for electrically connecting with the contacts of the card edge connector. The board hold downs are separated from the card edge connector and hold the daughter card in the card edge connector.

An electrical system (1) includes a number of PC boards (10, 12), a same number of electrical connectors (14, 16), and a half number of extenders (18, 20, 22) provided in sets. Each set includes two PC boards, two electrical connectors mounted onto respective PC boards and one extender located between and engaging with the two electrical connectors. There are extenders that have various heights so that extenders of different heights mating with the electrical connectors establish various distances between the PC boards mounting the electrical connectors.

An electrical connector (1) straddle-mounted on an edge (20) of a printed circuit board (2) includes an insulative housing (10) having an elongated groove (11) for mating. A plurality of receiving channels (13) each used to receive a support subassembly (3) is formed adjacently to and communicated with the mating groove (11). The support subassembly (3) includes a base (30) with signal contacts (5) and a ground member (4) attached thereon. Every contact (5) includes an engaging end (51) exposed to the mating groove (11) and a tail end (52) extending out of the receiving channel (13) in a suspended status. And the ground member (4) includes a plurality of contacting legs (42) extending from the ground member (4) and being arranged to stagger with the tail end (52) of every contact (5) along the lengthwise of the connector (1). Several holding elements (43) are formed in a hook shape on one edge side of the ground member (4) to hook and be partially inserted into the apertures (22) formed on the housing (10) to stop further insertion of the support subassembly (3), and the holding elements (43) of the neighboring ground member (4) are inserted in the same apertures (22) so that they can establish a common ground path to reduce their needed contacting legs (42) to the printed circuit board (2).

A mating extender electrically engages with a pair of complementary connectors. The mating extender comprises an insulative housing having first and second mating sections, and a number of wafers parallelly assembled into the insulative housing. Each wafer comprises an insulative frame and a plurality of contacts each formed by a pair of electrically stacked semi-contacts. Each contact has an intermediate portion retained in the insulative frame, a pair of first contact tails and a pair of second contact tails at opposite ends of the intermediate portion and received in the first and the second mating sections of the insulative housing, respectively.

A connector module for receiving a signal converter and electrically connecting the signal converter to a printed circuit board mounted within an electronic system. The connector module includes a conductive cage having a plurality of press-fit type pins and a shielding lid. The connector module further defines a top opening and a cavity with an opening on a bottom portion of the conductive cage for receiving the connector which electrically connecting with the signal converter. The shielding lid covers on the top opening. The connector comprises a plurality of contacts each having a press-fit end, said press-fit ends extending toward the printed circuit board and mounting therein.

A ground bus (4) for use with an electrical connector (1) includes a plane body (40) for electrical engagement with a corresponding ground contact of a mating connector, a number of solder tails (42) extending from the plane body and a carrier strip (46) connecting with the solder tails. The ground bus has a number of fingers (460) extending from the carrier strip. The fingers extend into space (320) between adjacent signal contacts (3) after the ground bus is assembled to the connector. Each solder tail (42) has a solder joint (420) for electrical connection to a printed circuit board (8). A bringing element (422) interconnects two adjacent solder tails at the solder joint.
