Abstract:
A socket terminal assembly includes a socket body having an end with an opening and an opposite end configured to contact the corresponding connection region of a printed circuit board, a contact spring, disposed at the opening of the socket body, to receive and apply a frictional force sufficient to retain the lower end of a pin within the opening of the socket body; and a resilient member, disposed within a lower end of the opening, to apply, to the pin and in response to a downward force applied to the pin, an upward force sufficient to overcome the frictional force of the contact spring. The pin has an end adapted to contact an electrical contacting area of an integrated circuit package and an opposite end configured to be inserted within the opening of the socket body. An intercoupling component includes a socket support member having holes, each hole receiving a corresponding socket terminal assembly.
Abstract:
IMPROVED SOCKET TERMINAL POSITIONING METHOD AND CONSTRUCTION MURRAY JAMES V. An improved method and construction for positioning a plurality of socket terminals on an electrical circuit board in a predetermined configuration prior to the solder connection thereto. A sheet of electrically insulative, flexible, resinous plastic material is provided with a plurality of holes in an array conforming to the desired positioning of the sockets on the circuit boards. The socket terminals are provided with an enlarged generally cylindrical head including an intermediate groove such that the heads extend into the holes and are adapted for frictional snap engagement with the sheet. The sheet with the array of sockets temporarily held thereby is positioned on the circuit board which is then conventionally soldered so as to electrically and mechanically fix the sockets to the board, Thereafter, the sheet may be removed. The enlarged head of the circuit terminal is provided with leading edge sheet contacting surface to enable the terminals to be push positioned into the holes without injuring the sheet.
