## Abstract

A multiconductor cable (10) including a large number of coaxial conductor pairs (16), with the coaxial conductor pairs arranged in groups (14) each including several of the coaxial conductor pairs arranged in a required order as a modular array (18) with each of the conductor pairs of each array being held in a required position with respect to the others and supported with a portion of each central conductor (54) and each shield conductor (47) exposed at a predetermined position, for connection of the array to a corresponding array (28) of terminal pads (24, 26) on a circuit board (30) or the like. Each array includes support bodies (32, 34) of flexible dielectric sheet material adhesively attached to the coaxial conductor pairs to support them in the required positions. Apertures (70, 76) are defined in the sheet material to expose the conductors for simultaneous soldering to, or unsoldering from, the terminal pads (24, 26), without removal of the support bodies (32, 34) from the coaxial conductors.

## Claims

### Claim 1

A termination for coaxial cables comprising at least one insulating support body,
multiple coaxial cables for electrical connection to a circuit, the coaxial cables being constructed, respectively, with central conductors within dielectric layers, conductive shields tightly arranged about the dielectric layers, and insulating jackets over the shields,
main body portions of the jackets being attached to the support body,
short lengths of the jackets being displaced from the main body portions of the jackets to reveal exposed portions of the shields, the short lengths of the jackets being attached to the support body to hold the exposed portions of the shields in positions for connection with the circuit,
the short lengths of the jackets surrounding respective distal portions of the shields,
the exposed portions of the shields being maintained tightly arranged about the dielectric layers by the short lengths of the jackets surrounding said distal portions of the shields, while being in said positions for connection with the circuit, and
exposed portions of the central conductors extending beyond the short lengths of the jackets and being attached to the support body while being in positions for connection with the circuit.

### Claim 2 (depends on 1)

A termination as recited in claim 1, and further comprising: projecting portions of the dielectric layers projecting beyond said distal portions of the shields, and annular air gaps between the short lengths of the jackets surrounding the projecting portions of the dielectric layers.

### Claim 3 (depends on 2)

A termination as recited in claim 2, and further comprising: the short lengths of the jackets being longer than the projecting portions of the dielectric layer.

### Claim 4 (depends on 1)

A termination as recited in claim 1, and further comprising: ends of the central conductors extending from the exposed portions of the central conductors, and
separated portions of the dielectric layers surrounding said ends of the central conductors.

### Claim 5 (depends on 1)

A termination as recited in claim 1, and further comprising: ends of the central conductors extending from the exposed portions of the central conductors, separated portions of the dielectric layers surrounding said ends of the central conductors, and
the separated portions of the dielectric layers being surrounded by separated portions of the shields and separated portions of the jackets.

### Claim 6 (depends on 1)

A termination as recited in claim 1, and further comprising: the exposed portions of the shields extending over an aperture through the support body, and the short lengths of the jackets being attached by the support body adjacent the aperture.

### Claim 7 (depends on 1)

A termination as recited in claim 1, and further comprising: the main body portions of the jackets being attached to a support member strip on the support body.

### Claim 8 (depends on 1)

A termination as recited in claim 1, and further comprising: the short lengths of the jackets being attached to a corresponding support member strip on the support body.
