Abstract
Abstract Disclosed is an improvement relating to a thin, applied-to-surface type of electric connector comprising a housing 1 and a plurality of terminals (9, 12) fixed thereto. Each terminal has a solder tail (8, 11) extending outward under the bottom (31) of the housing to be positioned on a selected conductor of a printed circuit board for subjecting to automatic soldering. The distance N between the ends (8A, 11A) of opposed solder tails is shorter than the maximum lateral size L of the housing 1. Both sides of the housing 1 have a chamfer 13 along its lower longitudinal part. The ends of the terminals and their receiving cavities may be slanted to hold the terminals within the housing and prevent stubbing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
281 words
In an electrical connector for surface mounting to a circuit board, including: an elongate dielectric housing (10) having a board mounting face (3) and a pair of stabilizing projections (1A, 1B) extending in opposite directions outward from sidewalls (5,6) of said housing away from the longitudinal centerline of said housing, and a pair of rows of terminal receiving cavities (22) including a portion extending through said mounting face, said rows being positioned on opposite sides of the longitudinal centerline of said housing and extending in a direction generally parallel to said longitudinal centerline; a plurality of terminals (9,12) secured within respective ones of said cavities, each terminal including a contact portion (7,10) for contacting a mating electrical component, securing means for securing said terminal within said housing and a tail portion (8,11) for soldering said terminal to a selected conductor on said circuit board, a portion of said tail portion extending under said board mounting face, the tail portions of the terminals positioned in one of said rows of cavities extending in a first direction away from said longitudinal centerline and the tail portions of the terminals positioned in the other of row of cavities extending in a second, opposite direction away from said longitudinal centerline, said tail portions being generally perpendicular to said contact portions; characterized in that: the lateral distance (N) between the ends (8A, 11A) of tail portions of the terminals positioned in the two rows of cavities is less than the lateral distance (L) between the two oppositely extending stabilizing projections (1A or 1 B); and the sidewalls have a recess (13) adjacent the board mounting face to facilitate bending of the tail portion of the terminals.
