Abstract
Abstract A contact strip has a continuous carrier (l00) with laterally extending contacts (80) each comprising a contact section with a base (82) and a pair of opposed contact arms (84,90) having facing rolled contact surfaces (88,95). A pin (97) is stamped out of one contact arm (95) leaving a close-ended slot (9l). Each arm (84,90) extends from the base (82) to a bend (87,94) through an obtuse angle towards the opposed arm. The other arm (84) is stamped from the carrier strip (l00) leaving an aperture (l02) so that a contact (80) is secured to the carrier by a pair of straps (l04) which support the contact against twisting relative to the strip and facilitate insertion into a housing. The straps (l04) may be severed to separate the contacts (80) from the strip.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
207 words
A strip of stamped and formed electrical contacts (80) of the type comprising a continuous carrier strip (l00) having the contacts (80) attached laterally thereto in side-by-side relation, each contact (80) comprising a contact section having a base (82) and a pair of first and second opposed arms (84, 90) formed upward from the base (82), the arms (84, 90) being formed with respective mutually facing rolled contact surfaces (88, 95), each contact (80) further comprising a pin (97) stamped out of the second arm (95) leaving a close-ended slot (9l) therein, the pin (97) being formed downward from the base (82), the strip being characterised in that each arm (84,90) of each contact extends from the base (82) to a bend (87, 94) remote therefrom where it is formed through an obtuse angle toward the opposite arm of the pair thence to the contact surface (88, 95), the first arm (84) being stamped from the carrier strip (l00) leaving an aperture (l02) therein, each contact (80) being attached to the carrier (l00) by a pair of straps (l04) extending from opposite sides of the aperture (l02) to respective opposite edges of the first arm (84) proximate to the bend (87) therein remote from the base (82).
Claim 2
Dependent Claim
207 words
A strip of stamped and formed electrical contacts (80) of the type comprising a continuous carrier strip (l00) having the contacts (80) attached laterally thereto in side-by-side relation, each contact (80) comprising a contact section having a base (82) and a pair of first and second opposed arms (84, 90) formed upward from the base (82), the arms (84, 90) being formed with respective mutually facing rolled contact surfaces (88, 95), each contact (80) further comprising a pin (97) stamped out of the second arm (95) leaving a close-ended slot (9l) therein, the pin (97) being formed downward from the base (82), the strip being characterised in that each arm (84,90) of each contact extends from the base (82) to a bend (87, 94) remote therefrom where it is formed through an obtuse angle toward the opposite arm of the pair thence to the contact surface (88, 95), the first arm (84) being stamped from the carrier strip (l00) leaving an aperture (l02) therein, each contact (80) being attached to the carrier (l00) by a pair of straps (l04) extending from opposite sides of the aperture (l02) to respective opposite edges of the first arm (84) proximate to the bend (87) therein remote from the base (82).
Claim 3
Dependent Claim
57 words
A strip as in claim l characterised in that each pin (97) is split along a close-ended shear line (98) proximate the base (82), the pin (97) comprising a pair of retaining portions (99) flanking the shear line (98), the retaining portions (99) being formed in opposite directions parallel to the plane of the shear line (98).
Claim 4
Dependent Claim
19 words
A strip as in claim l characterised in that all forming axes of the contact (80) are mutually parallel.
Claim 5
Dependent Claim
36 words
A strip as in claim l characterised in that each contact surface (88,95) lies on a bend where the arm is formed away from the opposite arm of the pair to a distal end (89, 96).
Claim 6
Dependent Claim
64 words
A strip as in claim l characterised in that each contact section has an aperture (86) stamped therein proximate to where the first arm (84) is formed upward from the base (82), the first arm (84) and the aperture (86) being profiled such that the spring characteristic of the first arm (86) is substantially similar to the spring characteristic of the second arm (90).
Claim 7
Dependent Claim
17 words
An electrical contact formed from a strip as claimed in claim l by severing the straps (l04).
