Abstract:
A hermaphroditic terminal assembly (10) for connecting electrical devices includes an insulating support member (20) for supporting female sockets (22) and male pins (34), a number of female sockets (22), and a number of male pins (34). An intercoupling component (19) for connecting electrical devices includes two hermaphroditic terminal assemblies (16, 18) configured such that the first hermaphroditic terminal assembly (16) can be mated with the second hermaphroditic terminal assembly (18).
Abstract:
A compression device has a frame sized to accept an integrated circuit package and a pressor. The frame includes a surface defining an opening with an axis and at least one ramp extending from the surface. The ramp or ramps have upper and lower flat portions, substantially parallel with a plane perpendicular to the axis, and a sloped portion at an angle relative to the plane, the sloped portion connecting the upper and lower flat portions. The pressor is configured to engage the ramp and rotate in response to applied force. When the pressor is engaged with the sloped portion(s) of the ramp(s), this rotation causes movement of the pressor along the axis. However, when engagement between the ramps and the pressor is in the flat portions of the ramp, continued movement of the pressor along the axis is limited in spite of any continued rotation.

Abstract:
An adapter to connect device leads (12) to contacts arranged in a rectangle on a circuit surface (30). The adapter has a body and leads (26) that extend outwardly, downwardly and then outwardly again in a pair of opposing curves to form feet which match the pattern on the circuit surface (30). The body has sites (16) for connecting with the device (10) and supports conductive elements connecting the leads to the sites. The adapter may connect gullwing-shaped device leads disposed in a rectangle (e.g., QFP) to contacts in a similar pattern. Strain relief elements (32) are shown. The body may include a stack of connected body portions. The device leads may be anchored in holes in the substrate, and may be bent portions of a lead frame sealed in a molded insulating body. Vertically extending resilient single-reed-shaped contacts (224) may connect to a surface of a downwardly extending section on a device package lead (214).
Abstract:
A male contact, a connector assembly of the type used to electrically connect electrical devices includes male contacts, and a method of manufacturing an electrical connector are disclosed.
Abstract:
An intercoupling component used to couple an array of electrical connection regions disposed on a first substrate to an array of electrical connection regions disposed on a second substrate. The intercoupling component includes an insulative support member including an array of holes extending therethrough, the array of holes located in a pattern corresponding to the array of electrical connection regions on the first substrate; and a plurality of terminals. Each terminal includes a socket including a socket head and a socket body, the socket defining a socket cavity; a pin including a pin head and a pin body, the pin head positioned within one of the array of holes, the pin body extending from the pin head and received at least partially within the socket cavity; and a resilient member configured to bias the socket head is biased away from the pin head.
Abstract:
A socket terminal assembly (18) includes a socket body (40) having a first end (41) with a first opening to receive a contact element (200) and a second opening at a second end to receive a pin (54). A contact element (200), located in the first opening, is configured to contact the corresponding connection region of a printed circuit board (14); a pin has an end (59) adapted to contact an electrical contacting area of an integrated circuit package (12) and an opposite end (58) configured to be inserted within the opening of the socket body (40). A contact spring (46) in the second opening receives the pin (54) and applies a frictional force sufficient to retain the lower end (56) of the pin (54) within the opening of the socket body. A resilient member (60) is disposed within the opening between the contact element (200) and the contact spring (46). The resilient member (60) applies to the pin and contact element (200), in response to a downward force applied to the pin (54) or an upward force applied to the contact element (200), a force sufficient to overcome the frictional force of the contact spring (46). An intercoupling component (16) includes a socket support member having holes (20), each hole (20) receiving a corresponding socket terminal assembly (18).

A ball grid array assembly (10) consists of a socket body (24) having a plurality of vias (30) extending therethrough, a plurality of electrically conductive contact assemblies (26) respectively disposed in corresponding vias (30), and a releasable cover plate (28). Each of the contact assemblies (26) includes a lower terminal end for engaging a terminal pad (14) on a circuit board (16), and further includes an upper multi-fingered contact arrangement (48) for engaging a ball contact (20) of a ball grid array package (12). Three separate embodiments are disclosed. In use, the ball grid array package (12) is received in assembled relation with the socket body (24) wherein the ball contacts (20) of the ball grid array package (12) are received into the vias (30) in engaging electrical communication with the upper contact ends of the contacts assemblies (26).
