Abstract
ABSTRACT OF THE DISCLOSURE An electrical connector (10) in which an electrical time delay circuit means (64) is mounted within a connector (10) to allow a remote location of said time delay circuit means. The connector (10) also includes setting recess means (28A, 28B) within the connector (10) to produce a setting action between electrical leads (A, B) and a C-clip terminal (18) having angled tips (20A, 20B) which wedge against an inserted lead (A, B).

3. An electrical connector as claimed in claim 1 or claim 2, wherein said terminal means includes clip ends of a conductive material adapted to grip a conductor within said housing cavity, said time delay circuit means being mechanically and/or electrically connected to said clip ends, to together form a unitary assembly and electrically connect said clip ends into said time delay circuit.
4. An electrical connector as claimed in claim 3, wherein said terminal means including clip ends, is sealed within said housing cavity.
5. An electrical connector for establishing a splice connection between electrical leads having an insulating jacket and a conductor core, including:
a hollow elongate connector body of ap electrically insulating material, having interior walls defining a cavity therein and having an opening at each end;
a C-clip of a strip of resilient, conductive material being disposed in said cavity, said C-clip having a pair of ends, each end extending from an elongate straight portion lying against an inner surface of one wall of said cavity of said connector body and extending lengthwise within said cavity, each of said ends being inclined towards the other and away from a respective adjacent opening of said connector body, each end having a tip lying at a point closely adjacent another inside surface of another wall of said cavity of said connector body, opposite the inside surface of said first mentioned wall, said tips being bent to decrease the obtuse angle and increase the acute angle otherwise existing relative to confining surfaces of said cavity; a contact recess formed into an edge of each tip, comprising a slot having closely spaced opposite edges adapted to slice through said insulating jacket and contact said conductor core as an electrical lead is pulled back after insertion into said connector body, to be seated within a contact recess, whereby an electrical lead may be inserted at either end to engage and deflect a respective C-clip end and move past said terminal edge, to thereby be gripped against pull-out by the edges of said contact recess spliced into said insulating jacket.
a hollow elongate connector body of ap electrically insulating material, having interior walls defining a cavity therein and having an opening at each end;
a C-clip of a strip of resilient, conductive material being disposed in said cavity, said C-clip having a pair of ends, each end extending from an elongate straight portion lying against an inner surface of one wall of said cavity of said connector body and extending lengthwise within said cavity, each of said ends being inclined towards the other and away from a respective adjacent opening of said connector body, each end having a tip lying at a point closely adjacent another inside surface of another wall of said cavity of said connector body, opposite the inside surface of said first mentioned wall, said tips being bent to decrease the obtuse angle and increase the acute angle otherwise existing relative to confining surfaces of said cavity; a contact recess formed into an edge of each tip, comprising a slot having closely spaced opposite edges adapted to slice through said insulating jacket and contact said conductor core as an electrical lead is pulled back after insertion into said connector body, to be seated within a contact recess, whereby an electrical lead may be inserted at either end to engage and deflect a respective C-clip end and move past said terminal edge, to thereby be gripped against pull-out by the edges of said contact recess spliced into said insulating jacket.
6. An electrical connector as claimed in claim 5, wherein plug means are adapted to fit into each end of said cavity, said plug means being provided with means opening and extending into said cavity; a set recess being defined between each of said plug means and including a step in inside surface(s) located outwardly of each C-clip end tip, prior to pulling out of said C-clip tip, creating an increased space outside of said tips and adjacent said respective plugs, so as to allow a respective tip to move into said increased space as said C-clip end is pulled out, whereby said tip and electrical lead may be wedged into said set recess to secure said connection.
7. An electrical connector as claimed in claim 6, wherein each of said tips is inclined with respect to the remaining C-clip end portion to increase the obtuse angle between said inside surface and said tip.
8. An electrical connector as claimed in claim 6, wherein each of said plugs has a shaped contour facing respective C-clip ends, to receive said C-clip ends thereagainst upon setting of said electrical lead.
9. An electrical connector as claimed in claim 6, wherein said C-clip is fixed in said housing cavity against lengthwise movement therein.
