Abstract
Abstract Slotted resilient wire-connectors or contact elements are removably disposed in an elongate array and are rapidly forcibly applied seriatim to electrical conductors supported across slots in receptor bases on electrical apparatus to make rapid solderless spring compression reserve contact with the electrical conductors.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
A method for rapidly making a series of electrical connections in the assembling of electrical apparatus, comprising the steps of: providing an electrical apparatus with a conductor support base formed to support an electrical conductor across a contact element receiving slot therein, feeding a plurality of spring compression reserve contact elements appressed together in tandem seriatim to an application position in a contact element applicator, aligning the application position of the applicator with the contact element receiving slot in the conductor support base, rapidly forcing the spring compression reserve contact element at the application position over a conductor and into the contact element receiving slot to form spring compression reserve contact with the conductor, and repeating said steps with additional conductors and contact elements.
Claim 2
Independent Claim
124 words
A method for rapidly making a series of electrical connections in the assembling of electrical apparatus, comprising the steps of: providing an electrical apparatus with a conductor support base formed to support an electrical conductor across a contact element receiving slot therein, feeding a plurality of spring compression reserve contact elements appressed together in tandem seriatim to an application position in a contact element applicator, aligning the application position of the applicator with the contact element receiving slot in the conductor support base, rapidly forcing the spring compression reserve contact element at the application position over a conductor and into the contact element receiving slot to form spring compression reserve contact with the conductor, and repeating said steps with additional conductors and contact elements.
Claim 3
Dependent Claim
46 words
The method of claim 1 wherein the applicator has an indexing structure and the conductor support base includes cooperating indexing means, and wherein said aligning step comprises bringing together the indexing structure and the indexing means prior to the step of rapidly forcing the contact element.
Claim 4
Independent Claim
119 words
A system for rapidly making a series of electrical connections in the assembling of electrical apparatus, comprising: an electrical apparatus having a conductor support base formed to support an electrical conductor across a contact element receiving slot therein, a contact element applicator for rapidly forcing a spring compression reserve contact element at an application position therein over a conductor and into said contact element receiving slot to form spring compression reserve contact with the conductor, means for feeding a plurality of spring compression reserve contact elements appressed together in tandem seriatim to said application position in said applicator, and means for aligning said application position in said applicator with said contact element receiving slot in said conductor support base.
Claim 5
Independent Claim
119 words
A system for rapidly making a series of electrical connections in the assembling of electrical apparatus, comprising: an electrical apparatus having a conductor support base formed to support an electrical conductor across a contact element receiving slot therein, a contact element applicator for rapidly forcing a spring compression reserve contact element at an application position therein over a conductor and into said contact element receiving slot to form spring compression reserve contact with the conductor, means for feeding a plurality of spring compression reserve contact elements appressed together in tandem seriatim to said application position in said applicator, and means for aligning said application position in said applicator with said contact element receiving slot in said conductor support base.
Claim 6
Dependent Claim
26 words
The system of claim 3 wherein said means for aligning comprises an indexing structure on said applicator and cooperating indexing means on said conductor support base.
