Abstract
An electric contact element comprises a bent portion. The bent portion has a cross-section including at least one of a plastically flattened side in the bent portion or a corner that has a chamfer in the bent portion for maintaining accuracy of a bending process used to form the bent portion.
Claims19
An electric contact element, comprising:
- a linear portion;
- and
- a bent portion extending from the linear portion and having a cross-section including:
- a corner that has a chamfer inclined between 30 degrees and 60 degrees, relative to at least one of an adjacent side, at least in the bent portion, the chamfer disposed at an end of a fracture section of a sheared side of the cross-section;
- and
- a plastically flattened side arranged only in the bent portion.

A blank, comprising:
- a strip of a plurality of interconnected electric contact elements, each of the electric contact elements including a bent portion having a cross-section with a corner that has a chamfer inclined between 30 degrees and 60 degrees, relative to at least one of an adjacent side, at least in the bent portion and a radially inward facing plastically flattened side formed only in the bent portion.
An electric connector, comprising:
- a plurality of electric contact elements each including:
- a linear portion;
- a bent portion extending from the linear portion and having a cross-section with a corner that has a chamfer inclined between 30 degrees and 60 degrees, relative to at least one of an adjacent side, formed only in the bent portion.
A method of manufacturing an electric contact element, comprising:
- forming the electric contact element by shearing;
- after the forming step, flattening a side of the electric contact element by plastic deformation;
- chamfering a corner of a cross-section of the electric contact element;
- and
- bending the electric contact element in a bent portion of the electric contact element, the corner has a chamfer inclined between 30 degrees and 60 degrees, relative to at least one of an adjacent side, at least in the bent portion.
