Abstract: A self-retained slider contact pin has a first contact which is coined to form a first notch and a first finger, and a second notch and a second finger. The first finger and the second finger extend longitudinally relative to the first contact and generally parallel to the first notch and the second notch. A second contact is coined to form an opening and a first channel, and a second opening and a second channel. The first contact and the second contact inter-fit in alignment with the first finger extending through the opening and into the first channel and the second finger extending through the second opening and into the second channel, such that the first finger and the second finger retain together in sliding engagement the first contact and the second contact. A bias spring pushes apart the first contact and the second contact.

Abstract: A spring contact (12) has a tail contact (14) and a tip contact (16) which are secured together in a telescoping arrangement. The tail contact (14) is formed as a first single element member (22) having two contact arms (28) which are spaced apart and extend forward to engage the tip contact (16). Two contact protuberances (34) extend outward from respective edges the two contact arms (28). The tip contact (16) is formed of a second single element member (50) having two elongate sides (58) and a mounting protrusion (56) which rearwardly extend in parallel toward the tail contact (14). The two sides (58) extend in a cantilever arrangement and have two elongate slots (66) formed therein for receiving respective ones of the contact protuberances (34).

Abstract: A micro via adapter socket (12) is provided by a printed circuit board (30) having an upper layer (32), a lower layer (40) and intermediate interconnect layers (34, 36 and 38). The lower layer (32) has an array of mini vias (60) formed therein for receiving respective ones of mini-springs (62). A top plate (42) is secured above the upper layer (32). The top plate (42) has a plurality of micro-pin recesses (54) spaced apart for registering with respective ones of the micro vias (48) and receiving micro-pins (52). A bottom plate (44) is secured beneath the lower layer (40). The bottom plate (44) has a plurality of mini-pin recesses (66) for removably receiving respective ones of the mini-pins (64). The intermediate interconnect layers (34, 36 and 38) have conductive tracks (76) which electrically connect between the micro vias (48) and the mini vias (60).

Abstract: A clamping mechanism (18) for an IC socket (14) is disclosed having two moveable arms (36) which are spaced apart on opposite sides of the IC socket (14), with first ends pivotally secured to a fixed shaft (34) at moveable arm pivot points for moving from a lifted position to a lowered position, extending across the IC socket (14). Two clamp arms (38) are spaced apart on opposite sides of the IC socket (14), and have formed ends (40) pivotally secured to the second ends (166) of the moveable arms (36) at latch pivot points. The clamp arms (38) are configured such that, when the moveable arms (36) are disposed in the lowered positions and the clamp arms (38) are disposed in the clamping positions, a hooking shaft (32) is disposed in the self-locking positions in openings (156) in the clamp arms (38) such that upward forces applied to the moveable arms (36) will engage the hooking shaft (32) against the clamp arms (38) and urge the clamp arms (38) into the latched position.

Abstract: According to the present invention, an electrical connector includes a body having first and second portions. The connector also includes a plurality of first contacts situated in the first portion of the body. Each of said first contacts includes a first end portion configured to be coupled to a conductive member on a printed circuit board and a second free end portion situated within the first portion of the body to define a movable spring contact surface section. The connector further includes a plurality of second contacts situated in the second portion of the body. Each of said second contacts includes a first end portion configured to be coupled to a conductive member on the printed circuit board and a second end portion coupled to the second portion of the body to define a fixed contact surface section.

Abstract: A device is disclosed for making an electrical connection of the contacts of a D-type connector with the conductors of a multi-conductor flat cable assembly, where the pitch of the conductors in the cable assembly is different from that in the D-type connector, and the pitch ratio is not an integer. Contacts employed in the assembly have a portion intermediate conductor contacting end portions and which enables altering the relationship between the end portions in three directions to accommodate the difference in pitch between the conductors connected to one set of contact ends, and the conductors connected to the other set of contact ends, and yet provide the same degree of depth or penetration of contact ends for all of them.
