Abstract
Abstract An elongated electrical spring strip has an insulating housing comprising a base and a cover snap-locked together. Channels formed in the housing carry multiple parallel contact springs therein transversely to the longitudinal direction of the housing. Shoulders on each contact spring lock the spring into its channel in the housing. A square-sectioned connection pin with a right-angle bent portion is engaged between and may be spot-welded to the contact spring shoulders. The bent portion is captured in a recess between the housing base and the cover to prevent movement relative to the housing when a straight portion of the pin extending from the housing is connected to another electrical component.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
In a spring strip having an elongated insulating housing defining at least one channel therein, the improvement of a contact spring and connection pin comprising: a shoulder means on said spring for orienting said spring in said channel and electrically engaging said connection pin; the connection pin having a straight portion and a right-angle bent portion, the bent portion engaging said shoulder means and extending free thereof to an end, and the straight portion extending exteriorly of said housing coaxially with said channel; and the end of said bent portion of said pin being held in clamped engagement by the housing adjacent the channel, thereby to transfer force loads from said connection pin to said housing rather than to said contact spring.
Claim 2
Dependent Claim
122 words
In a spring strip having an elongated insulating housing defining at least one channel therein, the improvement of a contact spring and connection pin comprising: a shoulder means on said spring for orienting said spring in said channel and electrically engaging said connection pin; the connection pin having a straight portion and a right-angle bent portion, the bent portion engaging said shoulder means and extending free thereof to an end, and the straight portion extending exteriorly of said housing coaxially with said channel; and the end of said bent portion of said pin being held in clamped engagement by the housing adjacent the channel, thereby to transfer force loads from said connection pin to said housing rather than to said contact spring.
Claim 3
Dependent Claim
25 words
In a spring strip, the improvement of claim 1, wherein said connection pin is connected to said contact spring by at least one welding point.
Claim 4
Dependent Claim
31 words
In a spring strip, the improvement of claim 1, wherein said contact spring has a U-shaped base component forming said shoulder means, the connection pin being received between the arms thereof.
Claim 5
Dependent Claim
42 words
In a spring strip, the improvement of claim 1, wherein said housing comprises a base portion and a cover portion snap-lockable together and which together define adjacent said channel a recess in which said bent portion of said connection pin is clamped.
