摘要:
An electrical connector (1) includes an insulative member (10) defining two rows of slanted cavities (30) along a longitudinal direction thereof, two rows of conductive contacts (12) obliquely received in corresponding slanted cavities and two grounding plates (32) with over-molded insulative inserts (34) attached to the insulative member. Each grounding plate electrically contacts some selected conductive contacts via ribs (39) thereof, which are therefore grounding contacts, and is isolated from the other conductive contacts, which are therefore signal contacts. Each grounding plate has a number of enlarged tails (38) for elastically engaging with corresponding plated holes (54) in a mother board (46) that the electrical connector is adapted to be mounted on. The conductive contacts slide along the mother board upon insertion of a daughter board (52) to the electrical connector.

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 (1) includes an insulative housing (10) and a number of contacts (28) attached to the housing. The contacts each have a contact tail (36) downwardly extending beyond a mounting surface (32) of the insulative housing for inserting into throughholes (42) of a PCB (40). The contact tails are overlapped in pairs and each pair of contact tails is inserted into the same throughhole of the PCB. Some pairs of contact tails, called retention contact tails (68), have protrusions (52) deviating from each other for bearing against peripheral walls of the throughholes of the PCB thereby producing retention force. The other pairs of contact tails, called non-retention contact tails (70), do not have protrusions and do not interfere with peripheral walls of the other throughholes thereby reducing the insertion force. The retention contact tails can be modified to the non-retention contact tails by severing the protrusions therefrom.

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).

An electrical connector assembly (1) includes a card edge connector (20) used to be mounted on a mother board (10) and defining a slot (210), a daughter card (30), and a board hold down (40) for being mounted on the mother board. The daughter card includes a mating edge (31) inserted into the slot of the card edge connector, and a rear edge (32) opposite to the mating edge and defining an engaging hole (320). The board hold down is separated from the card edge connector and includes a pivot bracket (42) engaged with the engaging hole of the daughter card, and a pin latch (44) pivoted on the pivot bracket and having a latch portion (442) abutting against the rear edge of the daughter card for preventing the rear edge from rising upwardly.

An electrical connector (1) adapted for connecting a flexible board comprises an insulated housing (2) defining a number of retaining channels, a number of first and second contacts (3, 4) and a pressing member (5). Each first contact has a pivot portion extending in a longitudinal direction and functioning as pivot point for actuation of the pressing member. The pressing member has a number of passageways for receiving corresponding pivot portions. After the pivot portions are fully received in corresponding passageways, the second contacts are assembled in the retaining channels. The first contacts cooperate with the second contact to secure the pressing member in the longitudinal direction.
摘要:
A method for assembling an electrical connector (10) to the edge (18) of a printed circuit board (12). A machine (50) incorporates an actuating mechanism that requires only a single input motion to achieve a variety of functional motions within the machine. The machine includes a carriage assembly (54) that moves substantially vertically within the frame of the machine to sense the thickness of the circuit board and then to align the centerline of the connector held on fixture (280) with the exact center plane (44) of the board. A slide member (140) then moves toward the connector, causing a pair of comb members (252,254) to close into position in front of the moving connector. The solder tails (38,40) of the connector (10) then enter spaced slots (260) in the edges of the comb members for support and the connector housing engages the face (272) of the combs, pushing them toward the circuit board. Angled free ends of the solder tails (38,40) of the connector then engage the corners of upper and lower board surfaces (14,16) at the board edge (18), and the center row of ground bus posts (32) are forced into apertures (26) in the edge of the board by a pusher member (174) until they contact plated through holes (24) in the board while the outer rows of tails cam out to and bear against and along the two opposite major board surfaces and into contact with solder pads thereon.
摘要:
An electrical connector (10) of the type having an array of signal contacts (22) surface mountable to pads of a circuit board (20), with at least one ground bus (40) having a plurality of post sections (44,50,52) insertable into through holes (34) of the circuit board. At least two of the post sections (50,52) include protuberances (54,56) proximate free ends thereof adapted to bear against side walls of the respective through holes upon insertion thereinto, for deflection of the shanks (62,64) of the post sections in the opposite direction. The protuberance of each of the at least two post sections extends in opposed directions along the row of posts, thus cooperating to act as a clamp of modest force to retain the connector to the board prior to contact soldering. The deflectable shank (62,64) preferably has a reduced cross-sectional area at root (66,68) facilitating deflection in the plastic region.
