摘要:
The invention relates to the forces generated in the cantilever beam type contacts by deflecting pins or leads. More particularly, the invention teaches associating the cantilever beam with an elastomer which supplements the beam's capability of exerting force due to being deflected.

The present invention relates to the compliant section on contact elements which are received in plated through holes in printed circuit boards and are structured to hold such elements therein without soldering. More particularly, the invention discloses an improved structure relative to the legs forming the moving members of the compliant section. The invention further discloses an improved structure to stabilize the element against normal forces.

A zero insertion force (ZIF) connector is preassembled with electrical terminals in a dielectric housing. The housing is molded with integral features that facilitate snap on assembly of a camming mechanism for the terminals. A multiblade insertion tool enters the housing to register with the contacts and to drive the terminals into apertures of a circuit board.

A card edge terminal is provided with a longitudinally trifurcated portion defining a resilient beam which presses against a circuit card and provides a wiping action of its contact surface along the card. The wiping action will tend to clean away debris and contaminants.

An electrical terminal structure is disclosed which is provided with a flow deposited quantity or band of solder adhered to a selected portion of the terminal and limited from spreading over the surface of the terminal by the presence of a solder-nonwettable material adjacent to but not necessarily touching the terminal. A method of mounting the banded electrical terminals in plated apertures provided in a substrate is also disclosed, wherein the solder bands are applied to the terminals according to the above mentioned application technique. A technique of flattening the solder bands, and the resulting terminal structures having flattened solder bands adhered thereto are also disclosed. Flattening of the solder bands facilitates insertion of the banded terminals into the plated apertures by changing the shape of the solder bands and by reducing their structural integrity through the creation of numerous hairline fractures.

The present invention relates to zero insertion force card edge connectors with flexible film circuitry interconnecting the mother printed circuit board on which the connector is mounted and the daughter printed circuit card received in the connector. Actuation of cam means closes the connector and moves the circuit pads on the film up and down against the card circuit pads to provide wipe and back-wipe.

The invention disclosed herein relates to a biasing means provided in one end of a card-receiving slot of a card edge connector. The biasing means includes a spring loaded wedge slidably positioned in a sloping passage at one end of the slot. The wedge includes a vertical surface which engages a side of the card as the card is inserted in the slot. The wedge moving down the sloping passage increases the slot length to accommodate the card width without exerting significant longitudinal force against the end walls of the connector. Further, the wedge cannot be moved up the passage by an uneven force being exerted on the card; accordingly, the card can only be removed from the slot in a straight line.

The present invention relates to a connector into which a printed circuit board or card may be inserted and card guides associated with the connectors which guide and support the inserted card. More particularly, the connector consists of two housings having a common center card-receiving slot with terminals lining the walls thereof. Pins on the terminals pass through the base of the housings for insertion into a printed circuit mother board or the like. The guides have slots into which the edges of the printed circuit board slide. A flexible latch on the guides lock the boards against inadvertant movement.

Connector housings having as an integral part thereof, compensators to accommodate variation in circuit board thickness to enable a plurality of connectors to be mounted thereon simultaneously. More particularly, the compensators include depending, collapsible projections on the bottom surfaces of the housings which are selectively collapsed in response to the thickness of the board at each mounting site.
摘要:
A terminal is disclosed of the type in which a conductor is terminated by moving the conductor transversely of its axis into a slotted opening having a width less than the diameter of the wire. The terminal comprises two metal plates which pivot transversely of each other and which have individual slotted openings defined by slicing edges. The slotted openings overlie each other to provide a common wire-receiving opening so that a wire in either an upper section or a lower section of the common opening will tend to narrow the width of the corresponding other section.
