Abstract
Abstract An assembly for providing a common electrical connection between a number of separate external conductors. A plurality of electrically coupled socket contacts are mounted within a twopart insulating housing. Each socket contact is provided with an encircling spring element, having a detent extending into the exterior of the socket and a radially projecting spout portion on the exterior. The detent locks the socket to an inserted pin contact attached to an external conductor, and the spout receives a lever tool which deflects the spring element so as to disengage the detent. Contact openings and access openings in the housing are aligned respectfully with the sockets and the spout portions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
280 words
An electrical junction assembly, comprising: a housing of dielectric material, including a first part and a second part secured together defining an enclosure; a socket contact subassembly confined within the housing enclosure, including a plurality of generally tubular sockets coupled in side-by-side, spaced-apart relationship; a generally tubular spring band, resiliently encircling more than 360* of the periphery of a tubular socket, having a slit extending through the band from end to end at an angle to the central axis; and, means positioning each of said sockets relative to said housing; said spring band being characterized by: a front end, a back end, a spout-shaped radial projection at the front end tapered inwardly toward the back end to receive a lever instrument, and a transverse portion at the back end extending across the band generally in the nature of a cord across a circle; each of said sockets having: a forward end, a rearward end, a central bore extending through the forward end for receiving a mating pin, a generally flat outer surface portion extending longitudinally from the forward end, and an aperture spaced from the forward end extending radially through the flat outer surface portion into the central bore; said housing having a plurality of contact openings, located in alignment with the central bores of said sockets, and a plurality of access openings aligned with said spout-shaped projections; wherein, the spring bands are positioned on the tubular sockets with the spout-shaped projections aligned with the flat outer surface portion, and the transverse portion of the spring band is located within the aperture of the tubular socket forming a partial obstruction across the central bore for resiliently engaging a mating pin.
Claim 2
Dependent Claim
280 words
An electrical junction assembly, comprising: a housing of dielectric material, including a first part and a second part secured together defining an enclosure; a socket contact subassembly confined within the housing enclosure, including a plurality of generally tubular sockets coupled in side-by-side, spaced-apart relationship; a generally tubular spring band, resiliently encircling more than 360* of the periphery of a tubular socket, having a slit extending through the band from end to end at an angle to the central axis; and, means positioning each of said sockets relative to said housing; said spring band being characterized by: a front end, a back end, a spout-shaped radial projection at the front end tapered inwardly toward the back end to receive a lever instrument, and a transverse portion at the back end extending across the band generally in the nature of a cord across a circle; each of said sockets having: a forward end, a rearward end, a central bore extending through the forward end for receiving a mating pin, a generally flat outer surface portion extending longitudinally from the forward end, and an aperture spaced from the forward end extending radially through the flat outer surface portion into the central bore; said housing having a plurality of contact openings, located in alignment with the central bores of said sockets, and a plurality of access openings aligned with said spout-shaped projections; wherein, the spring bands are positioned on the tubular sockets with the spout-shaped projections aligned with the flat outer surface portion, and the transverse portion of the spring band is located within the aperture of the tubular socket forming a partial obstruction across the central bore for resiliently engaging a mating pin.
Claim 3
Dependent Claim
82 words
An electrical junction assembly in accordance with claim 1, wherein: said first part of said housing includes a generally elongate recess, with a front wall extending in the longitudinal direction having said contact and said access openings formed therein and with a back opening substantially opposite said front wall; said second part of said housing being a generally elongate plate member forming a closure against said back opening defining said enclosure and confining said socket contact subassembly against the said front wall.
Claim 4
Dependent Claim
80 words
An electrical junction assembly in accordance with claim 2, wherein: said first and said second parts of said housing each include extending mounting lugs at opposite longitudinal ends thereof having aligned openings; and, said means securing said first and said second parts together includes a mounting block having a transverse hole therethrough and a substantially tubular longitudinal extension disposed with the aligned openings of said mounting lugs having a flanged end portion preventing withdrawal of said extension from said openings.
Claim 5
Dependent Claim
77 words
An electrical junction assembly in accordance with claim 2, wherein: said means positioning said sockets relative to said housing includes a radial projection located on the outer surface of each socket between the front end thereof and the said aperture therein; the said forward end of each contact being disposed within a corresponding contact opening in said housing part, and said radial projection engaging said housing part to limit passage of said socket into said contact opening.
Claim 6
Dependent Claim
37 words
An electrical junction assembly in accordance with claim 2, wherein: said access openings comprise extensions of said contact openings, extending from the periphery thereof to define a combined, non-circular contact and access opening for each socket contact.
