Abstract
Abstract This invention relates to a series terminal with one or more connection terminal units for ground conductors and with a contact base for the assembly rail, in order to use it as a ground conductor bus bar. To improve the electrical connection between the ground conductor connection terminal points and the assembly rail, and for better handling of the terminal, it is suggested that a contact clamp with a spring bow be used instead of the contact base, with the contact clamp being made in one part with the bus bar of the connection terminal points.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
195 words
In a series terminal for use in connection with an elongated assembly rail of a type including a base portion, a pair of leg portions extending upwardly from opposite sides of said base portion, and a pair of side flange portions extending outwardly from the upper extremities of said leg portions terminating in elongated longitudinally extending side edges, said series terminal including a current bar which is electrically connectible to a ground connection, a contact base which is adapted to be latched to the assembly rail, and an insulator case including insulator latching bases for latching said insulator case to said assembly rail, the improvement comprising said contact base being integrally formed in a unitary construction with said current bar from a highly conductive metal and including a pair of spaced clamp ends which are receivable in clamping engagement with said opposite side edges so that said clamp ends are in substantially perpendicular relation to said base portion, said series terminal further comprising a resilient spring bow received on said contact base for resiliently urging the clamp ends thereof together in order to maintain said clamp ends in clamping engagement with said opposite side edges.
Claim 2
Dependent Claim
195 words
In a series terminal for use in connection with an elongated assembly rail of a type including a base portion, a pair of leg portions extending upwardly from opposite sides of said base portion, and a pair of side flange portions extending outwardly from the upper extremities of said leg portions terminating in elongated longitudinally extending side edges, said series terminal including a current bar which is electrically connectible to a ground connection, a contact base which is adapted to be latched to the assembly rail, and an insulator case including insulator latching bases for latching said insulator case to said assembly rail, the improvement comprising said contact base being integrally formed in a unitary construction with said current bar from a highly conductive metal and including a pair of spaced clamp ends which are receivable in clamping engagement with said opposite side edges so that said clamp ends are in substantially perpendicular relation to said base portion, said series terminal further comprising a resilient spring bow received on said contact base for resiliently urging the clamp ends thereof together in order to maintain said clamp ends in clamping engagement with said opposite side edges.
Claim 3
Dependent Claim
128 words
In the series terminal of claim 1, said contact base including a central back portion having opposite side edges and opposite ends, said clamp ends extending from opposite side edges of said central back portion, said current bar also including a central back portion having opposite side edges and opposite ends, the central back portion of said current bar being in closely spaced substantially parallel relation to the central back portion of said contact base, one end of the central back portion of said current bar being integrally connected to one end of the central back portion of said contact base, the central back portions of said current bar and said contact base cooperating to define a bending pocket therebetween, said spring bow passing through said bending pocket.
Claim 4
Dependent Claim
29 words
In the series terminal of claim 5, said insulator case including insulator stops which are engageable with said assembly rail for fixing the position of said series terminal thereon.
Claim 5
Dependent Claim
29 words
In the series terminal of claim 2, said insulator case including insulator stops which are engageable with said assembly rail for fixing the position of said series terminal thereon.
