Abstract
Abstract An electrical control device characterized by a drawout circuit breaker and spaced electrical stabs. The circuit breaker includes quick-detachable terminal connectors comprising a pair of oppositely disposed flexible stab contacts engageable with opposite sides of a stab and a spacer between the stab contacts for holding the stab contacts in spaced pre-loaded positions by a distance less than the thickness of the stab, whereby engagement of the stab contacts with the stab provides tight electrical contact therebetween.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A circuit breaker for use in drawout switchgear having spaced line stabs and including a circuit breaker and a stationary housing having stationary terminals, the stationary terminals being movable into and out of contact with the line stabs, the circuit breaker comprising a pair of separable contacts, means for moving the contacts between open and closed positions, first conductor means for connecting one of the contacts to one of the stationary terminals, second conductor means for connecting the other contact to the other terminal, each stationary terminal comprising a quick detachable terminal connector, each connector including a pair of oppositely disposed flexible terminal contacts engageable with opposite sides of a line stab, said oppositely disposed terminal contacts being spaced from each other by a distance less than the thickness of a line stab when out of contact with said stab, and a spacer between each pair of said terminal contacts, said space being flexibly mounted to yield in response to pressure from either side of the spacer.
Claim 2
Dependent Claim
167 words
A circuit breaker for use in drawout switchgear having spaced line stabs and including a circuit breaker and a stationary housing having stationary terminals, the stationary terminals being movable into and out of contact with the line stabs, the circuit breaker comprising a pair of separable contacts, means for moving the contacts between open and closed positions, first conductor means for connecting one of the contacts to one of the stationary terminals, second conductor means for connecting the other contact to the other terminal, each stationary terminal comprising a quick detachable terminal connector, each connector including a pair of oppositely disposed flexible terminal contacts engageable with opposite sides of a line stab, said oppositely disposed terminal contacts being spaced from each other by a distance less than the thickness of a line stab when out of contact with said stab, and a spacer between each pair of said terminal contacts, said space being flexibly mounted to yield in response to pressure from either side of the spacer.
Claim 3
Dependent Claim
30 words
The circuit breaker of claim 1, in which the terminal connectors are elongated members having corresponding end portions fixedly mounted and having other end portions adapted to receive a terminal.
Claim 4
Dependent Claim
31 words
The circuit breaker of claim 2, in which the terminal contacts comprise at least two members disposed on opposite sides of the spacer and retained by the spacer in spaced tension.
Claim 5
Dependent Claim
42 words
The circuit breaker of claim 3, in which the terminal contacts comprise a pair of flexible members on opposite sides of the spacer, the pair of members on each side comprising a longer outer terminal contact and a shorter inner terminal contact.
Claim 6
Dependent Claim
26 words
The circuit breaker of claim 4, in which the end portions of the terminal contacts are turned inwardly and outwardly for surface contact with the terminals.
Claim 7
Dependent Claim
81 words
The circuit breaker of claim 2, in which the spacer is an elongated element having one end portion seated between the fixedly mounted end portions of the elongated members, the element having another end portion between the pair of oppositely disposed flexible portions of the terminal contacts, and the element having a flexible intermediate portion which is deflectable in response to pressure from the terminal contacts on one side when pressure of the terminal contacts on the other side is removed.
