Abstract

Abstract An improved cutover block enabling a plurality of telephone circuits to be conveniently transferred from one switching location to another switching location. The cutover operation is performed manually by disconnecting a printed circuit board carried by the cutover block, rotating the board about 180° on its own axis, and reconnecting it to the cutover block to result in reconnecting the circuit to another location. For convenience, the cutover block is made to the same dimensions as a standard telephone connector block, so that it may be mounted conveniently on a frame adjacent an existing connector block with which it is associated.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 192 words
An auxiliary telephone connector block for use in changing the connection of individual telephone subscriber circuits from one switching equipment location to another switching equipment location, said block comprising: a generally planar frame element including a main wall, a plurality of elongated circuit board engaging means mounted upon a surface of said main wall, a corresponding plurality of planar circuit boards, each having first and second oppositely disposed surfaces, each of said first and second surfaces having differing circuits thereon; said circuit boards being selectively engaged in either of two orientations relative to a respective circuit board engaging means; first, second and third pluralities of terminals carried by said main wall adjacent each of said circuit board engaging means in such positions as to establish electrical communication with corresponding terminals on said circuit boards upon the engagement thereof; the circuits on said first and second surfaces of each of said circuit boards being so configured as to establish communication between said first and second pluralities of terminals when engaged in one of said orientations, and establish communication between said first and third pluralities of terminals when in the other of said orientations.
Claim 2
Dependent Claim 192 words
An auxiliary telephone connector block for use in changing the connection of individual telephone subscriber circuits from one switching equipment location to another switching equipment location, said block comprising: a generally planar frame element including a main wall, a plurality of elongated circuit board engaging means mounted upon a surface of said main wall, a corresponding plurality of planar circuit boards, each having first and second oppositely disposed surfaces, each of said first and second surfaces having differing circuits thereon; said circuit boards being selectively engaged in either of two orientations relative to a respective circuit board engaging means; first, second and third pluralities of terminals carried by said main wall adjacent each of said circuit board engaging means in such positions as to establish electrical communication with corresponding terminals on said circuit boards upon the engagement thereof; the circuits on said first and second surfaces of each of said circuit boards being so configured as to establish communication between said first and second pluralities of terminals when engaged in one of said orientations, and establish communication between said first and third pluralities of terminals when in the other of said orientations.
Claim 3
Dependent Claim 34 words
A connector block in accordance with claim 1, further characterized in the provision of hinged means for interconnecting said main wall to a telephone frame element in proximity to an existing telephone connector block.
Claim 4
Dependent Claim 50 words
A connector block in accordance with claim 2, including positioning stud means mounted upon and extending laterally from the plane of said main wall, said stud means being adapted to contact a surface of an existing telephone connector block to position the pivotal orientation of said first mentioned connector block.
Claim 5
Dependent Claim 35 words
A connector block in accordance with claim 1, further characterized in said printed circuit boards being provided with keying means to prevent engagement with said circuit block engaging means in other than said two orientations.
