Abstract
Abstract In a telephone repeater assembly, a plurality of fasteners is maintained in a self-supporting array by a framework of attached runners. The fasteners are aligned with and joined to a mating part in a pattern which substantially corresponds to the array. Flexibility of the runners permits minor adjustments to the positions of the fasteners in the array to align the fasteners precisely to the pattern on the mating part. Handling the fasteners in such an array facilitates assembly of the fasteners into the mating part. A circuit board is mounted to such part with one side thereof contiguous to the array of fasteners. The board has a plurality of apertures in addition to its mounting holes for the insertion of wide-headed contact screws. The screws are retained by the fasteners. Upon full insertion of the contact screws the head of the screws bridges a gap between two separate conductors on the board and establishes electrical continuity therebetween.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
278 words
A circuit board assembly comprising: a base having a flat surface, a plurality of cavities located according to a defined pattern in the flat surface, and a plurality of channels located in the plane of the flat surface, each of the channels connecting one of the cavities with at least one other adjacent one of the cavities; an array of fasteners comprised of a plurality of apertured blocks, and a plurality of runners interconnecting the blocks into a self-supporting structure, the runners positioning the blocks substantially according to the pattern of cavities in the base, each of the blocks occupying one of the cavities in the flat surface of the base, the runners being positioned within the channels; a circuit board located with one side thereof contiguous to the flat surface of the base and to the array of fasteners, the board having (1) a plurality of apertures arranged in a pattern which coincides with the pattern of cavities, the apertures in the board being coaxially aligned with the apertures of the fasteners located within the cavities, and (2) a circuit conductor pattern on a second side facing away from the base, the conductor pattern including a plurality of conductor pairs corresponding in number to the apertures through the board, each conductor pair straddling one of the apertures in the board; and a plurality of wide-headed contact screws inserted into each of the apertures in the board and extending through the board into locking engagement with the apertures of the fasteners, the head of each screw adapted to make contact with both conductors of the corresponding pair of conductors for establishing electrical continuity between such pair of conductors.
Claim 2
Dependent Claim
278 words
A circuit board assembly comprising: a base having a flat surface, a plurality of cavities located according to a defined pattern in the flat surface, and a plurality of channels located in the plane of the flat surface, each of the channels connecting one of the cavities with at least one other adjacent one of the cavities; an array of fasteners comprised of a plurality of apertured blocks, and a plurality of runners interconnecting the blocks into a self-supporting structure, the runners positioning the blocks substantially according to the pattern of cavities in the base, each of the blocks occupying one of the cavities in the flat surface of the base, the runners being positioned within the channels; a circuit board located with one side thereof contiguous to the flat surface of the base and to the array of fasteners, the board having (1) a plurality of apertures arranged in a pattern which coincides with the pattern of cavities, the apertures in the board being coaxially aligned with the apertures of the fasteners located within the cavities, and (2) a circuit conductor pattern on a second side facing away from the base, the conductor pattern including a plurality of conductor pairs corresponding in number to the apertures through the board, each conductor pair straddling one of the apertures in the board; and a plurality of wide-headed contact screws inserted into each of the apertures in the board and extending through the board into locking engagement with the apertures of the fasteners, the head of each screw adapted to make contact with both conductors of the corresponding pair of conductors for establishing electrical continuity between such pair of conductors.
Claim 3
Dependent Claim
60 words
A circuit board assembly according to claim 1, wherein the cavities have walls spaced from the surfaces of the blocks, the walls constraining rotational movement of the blocks within the cavities while permitting tilting or lateral floating of the blocks in response to inserted contact screws tilting upon contact of the heads of such screws with respective pairs of conductors.
Claim 4
Dependent Claim
96 words
An assembly comprising: a base having a plurality of cavities located according to a defined pattern in one surface thereof; an array of fasteners, interconnected by runners into a self-supporting structure, the fasteners located in accordance with the defined pattern in the cavities; a circuit board located with one surfacE thereof contiguous to the fasteners, the other surface of the board having a plurality of pairs of conductors thereon; and a plurality of screws inserted through the board into the fasteners, the screws adapted to establish electrical continuity between the conductors of each pair of conductors.
Claim 5
Dependent Claim
96 words
An assembly comprising: a base having a plurality of cavities located according to a defined pattern in one surface thereof; an array of fasteners, interconnected by runners into a self-supporting structure, the fasteners located in accordance with the defined pattern in the cavities; a circuit board located with one surfacE thereof contiguous to the fasteners, the other surface of the board having a plurality of pairs of conductors thereon; and a plurality of screws inserted through the board into the fasteners, the screws adapted to establish electrical continuity between the conductors of each pair of conductors.
Claim 6
Dependent Claim
30 words
An assembly in accordance with claim 3 wherein the fasteners and the runners are of glass filled nylon and the runners are integrally attached to respective ones of the fasteners.
Claim 7
Dependent Claim
54 words
An assembly in accordance with claim 3, wherein the cavities and the fasteners have a square cross section, and wherein the cavities have walls spaced from the surfaces of the fasteners, the walls constraining rotational movement of the fasteners within the cavities while permitting tilting or lateral floating of the fasteners within the cavities.
