ABSTRACT:
An electrical connection of a terminal contact to an electrical conductor is crimped by applying compressive force to the right and left sides of the barrel of the contact but not at the center and not applying it directly toward the center, thus forming an "oblique" crimp. Such an oblique crimp can be formed using a punch die and an opposing anvil die each having a crimping surface with a central recessed relief area whereby the crimping surface does not compress the center of the contact barrel. On each side of the relief area is a substantial diagonal portion of the crimping surface, and outward therefrom is a transverse shoulder, both of which engage the contact barrel during crimping. This crimping is especially useful for contacts having closed or seamless barrel walls and also especially for crimping a slightly oversized barrel to a many-stranded conductor without an intermediate sleeve, and it is particularly useful where confined crimping is required. The use of only two opposing dies more economically and efficiently enables fully automated feeding and terminating procedure; the dies can also be used in a manual crimping tool.
