CRIMPING TOOL HEAD WITH REINFORCING BEAMS FOR OPTIMIZING WEIGHT

摘要

A head (10) for a crimping tool assembly (12) comprises a generally ~C~ shap ed body (14) which can withstand repeated tensile forces. The ~C~ shaped body (14) comprises an elongated beam portion (26) and a first arm (50) extending in a given direction from a first end of the beam portion (26) and a second arm (34) extending in the given direction from an opposing end of the beam portion (26). The beam portion (26) has opposed first and second elongated sides (15 and 17), with the plane of the first and second sides extending generally parallel to the given direction (N). The beam portion (26) also ha s an inside elongated third side (30) extending transversely of the given direction (N) between the first and second sides (15 and 17). The beam porti on (26) further includes an outside elongated fourth side (58) extending transversely of the given direction (N) between the first and second sides ( 15 and 17). The third and fourth sides (30 and 58) of the beam (26) comprise continuous walls of a given thickness. The beam portion (26) has a plurality of internal support ribs (16) which extend between the first and second side s (15 and 17) transversely of the given direction (N). The ribs (16) are connected at one end to the third sidewall (30) and at their opposing end to the fourth side wall (58). The beam portion (26) also has a plurality of openings or depressions (18 and 20) in the first and second sides (15 and 17 ) for reducing the weight of the beam portion (26), the openings or depression s (18 and 20) are disposed in lower stress regions of the beam portion (26).
