Abstract
Abstract A connector for use in a track lighting system is provided. The connector comprises a housing formed of at least two nonconductive members one overlying the other. A cavity extends through the housing at the interface of the members and terminates in openings at opposite ends of the connector. A contact is positioned within the cavity and is designed to permit a conductor to enter the cavity through an opening but resists removal of the conductor from the opening. The housing is held together by two fasteners one of which has a coil spring wound about it so that when the fastener is loosened, the coil spring serves to urge the housing members apart to thereby enable the contact to disengage from the conductor.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
209 words
A connector for use in a track lighting system, said connector comprising: a generally rectangularly shaped housing formed of at least two nonconductive members, one of said members overlying the other; a first cavity extending through the housing at the interface of said members, said cavity terminating in at least two openings on the surface of the housing extending through opposite sides of said housing; a first electrically conductive contact positioned within said cavity, said contact including a tab portion extending into a path aligned with one of said openings, said tab portion having surfaces contoured to engage and secure an electrical conductor positioned into said one opening and to pooise the removal of said electrical conductor from said one opening; fastener means securing said housing members together thereby causing said contact portions to securely engage said electrical conductor, said fastener means including a first fastener at one of said opposite sides and a second fastener at the other of said opposite sides; and, coil spring means disposed within said housing extending about one of said fasteners and biased to urge at least one of said members in the direction of the axis of said one fastener to facilitate separation of said members when said one fastener is loosened.
Claim 2
Dependent Claim
209 words
A connector for use in a track lighting system, said connector comprising: a generally rectangularly shaped housing formed of at least two nonconductive members, one of said members overlying the other; a first cavity extending through the housing at the interface of said members, said cavity terminating in at least two openings on the surface of the housing extending through opposite sides of said housing; a first electrically conductive contact positioned within said cavity, said contact including a tab portion extending into a path aligned with one of said openings, said tab portion having surfaces contoured to engage and secure an electrical conductor positioned into said one opening and to pooise the removal of said electrical conductor from said one opening; fastener means securing said housing members together thereby causing said contact portions to securely engage said electrical conductor, said fastener means including a first fastener at one of said opposite sides and a second fastener at the other of said opposite sides; and, coil spring means disposed within said housing extending about one of said fasteners and biased to urge at least one of said members in the direction of the axis of said one fastener to facilitate separation of said members when said one fastener is loosened.
Claim 3
Dependent Claim
47 words
The invention in accordance with claim 1 further comprising a second cavity extending through the housing at the interface of said members, a second electrically conductive contact similar to said first contact positioned within said second cavity, said second cavity extending generally parallel to said first cavity.
Claim 4
Dependent Claim
51 words
The invention in accordance with claim 2 wherein said housing includes a top surface and further comprising paths extending through one of said members between said top surface and said cavities terminating in openings on said top surface whereby conductors may be fed through said top surface openings to said contacts.
Claim 5
Dependent Claim
59 words
The invention in accordance with claim 1 further comprising a third nonconductive member overlying said two members, another cavity extending through said housing at the interface of said third member and said two members, said other cavity terminating in at least two openings on said housing, and a contact similar to said first contact positioned within said other cavity.
