Connector with press-fit terminal pins

摘要

An electrical connector includes a dielectric housing having a plurality of apertures receiving a plurality of terminals having pin portions projecting from the housing for insertion into complementary holes in a printed circuit board. At least some of the terminals are mounted in the housing for movement between first and second positions in response to mounting the connector to the printed circuit board. In the first position, the terminals are fixed relative to the housing to facilitate alignment and insertion of the pin portions into the holes in the printed circuit board. In the second positions, the terminals can float relative to the housing to accommodate a differential in thermal expansion between the housing and the printed circuit board. Other terminals are mounted in the apertures and maintained in a fixed position relative to the housing when some of the terminals are in floating positions. An insertion tool having a flat bottom surface applies an insertion force to the top of the housing and also defines an upper limit for movement of the terminals within the housing.
