摘要:
Chip carrier sockets (2) have terminals (4) provided therein, the terminals (4) comprising leg portions (34) with first resilient arms (18) and second resilient arms (20) pivotally attached thereto. The first resilient arms (18) have contact surfaces (26) provided on free end sections (22) thereof. The contact surfaces (26) are provided to electrically engage leads (6) of the chip carrier (8). A cover (12) is provided to cooperate with the chip carrier and to act as a protective handler for the chip carrier. Retention means are positioned on the chip carrier socket (2) to cooperate with the cover (12), thereby providing the contact force required to insure that a positive electrical connection is effected between the leads (6) and the terminals (4). The resilient configuration of the retention means insures that the retention means will not fail under normal stresses associated therewith.

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.

A printed circuit board (1) for a straddle mount electrical connector (2) includes a first side surface (10) and a second side surface (12) opposite to the first side surface. Each of the side surfaces has a front and a rear rows of conductive pads (14), (16) and the conductive pads in the front row are staggered with respect to the conductive pads in the rear row. A number of solder pastes (11), (13) are applied through a solder stencil (18) to the conductive pads wherein each solder paste corresponding to the conductive pad in the front row is narrower and longer than the conductive pad. The straddle mount electrical connector has staggered signal and grounding contacts (221), (222) respectively secured to the front and the rear rows of conductive pads of the printed circuit board.

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.

A connector assembly (100) includes a mother board (12), a mother receptacle (11), a daughter board (22), a daughter receptacle (21), and a connecting device (30) mounted between said two boards. The connecting device includes a shroud (31), a pair of standoffs (32) mounted at opposite sides of the shroud and engageable with the two boards, and an extender (33) positioned alongside the shroud and between the pair of standoffs. The extender defines a lower interface (332) mating with the mother receptacle and an upper interface (331) mating with the daughter receptacle.

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.

A high density, high speed, low profile, electrical connector (100) includes a housing (10) and conductive contacts (20) partially positioned in the housing. The housing has a base (11) defining therethrough a number of passageways (114). Each contact has a body portion (21) and a pair of cantilevered beams (22) extending from the body portion. A retaining tab (212) is stamped from the body portion and abuts against a projection (116) formed in the passageway for protect the housing from possible movement with respect to a board on which the connector is mounted. The connector also has a stabilizer (30) assembled to the housing.

An electrical connector for connecting a sheet-like member includes a housing (1) defining an insertion slot (10); a plurality of terminals (2) arranged in the housing in parallel relationship with a predetermined pitch, each of the terminals having a contact beam (22) extending into the insertion slot and a pivot beam (21) extending substantially parallel to the contact beam; and an actuator (3) rotatably provided for establishing an electrical connection between the sheet-like member and the contact beams. The actuator provides cam portions (31) each interposed between every other the pivot beam. Each of the cam portions provides shaft portions (32) respectively adapted for pivotably engaging with the pivot beams disposed therebeside. The shaft portions extending towards each other respectively from two adjacent cam portions are spaced to define a gap (33) therebetween.

An electrical device (100) for interconnecting two parallel printed circuit boards at a large distance includes a plug connector (1), a receptacle connector (1′), and a mating extender (2) disposed between the plug connector and the receptacle connector. The mating extender includes a subassembly of wafer (21), a pair of identical caps (20) disposed on the top and bottom portions of the subassembly of wafer, and a pair of shroud-halves (22) sliding on the subassembly of the wafer. The subassembly of wafer is made up of a number of wafer modules (24) parallel with each other. Each wafer module has a wafer support (26) and a number of contacts (28) embedded in the wafer support.
