Abstract
Abstract The invention relates to a one-piece free standing terminal adapted for use with a circuit board having a terminal receiving opening formed therein. The terminal consists of a contact portion having a single pair of bows bent to form a lead receiving funnel terminating in a contact throat, a seating flange, a resilient neck connecting the contact portion to the seating flange, a terminal retention area and a tail extending from the terminal retention area and adapted to have a conductor connected thereto. The terminal retention area is shaped to coact with the terminal receiving opening in the board to frictionally retain the terminal in the board. In order to permit the terminal to be withdrawn and reinserted in the board the terminal retention area may have a non-symmetric cross-section or a fixture may be provided to permit at least one dimension of the terminal retention area to be expanded in the field. The terminal may be constructed from two like blanks bent into an overlaying relationship with each other or it may be formed from dual thickness material.
