<p>1,121,742. Two-part couplings. WESTERN ELECTRIC CO. Inc. 11 Nov., 1965 [17 Dec., 1964], No. 47854/65. Heading H2E. A multicontact connector comprises an insulating body formed from plates 22a-22e, each having a series of spaced grooves extending completely across one surface, the other surface being flat so that when the plates are stacked together they form individual cells into each of which a contact 24 is inserted. The contacts are soldered to the conductors of a cable before being inserted into the body and remain connected together in groups by strips of material forming part of the blank from which they were initially stamped until after they have been inserted into the body when the strips are removed. The connector is used to interconnect colour-coded telephone cables, each cable comprising twenty-five pairs of separately insulated conductors, each conductor of a pair having differently coloured insulation from the other member of the pair, and the two colours together forming a unique combination for that cable. The colours used for the insulation are arranged in two groups, the examples given being white, red, black, yellow and violet for the first group and blue, orange, green, brown, and slate for the second group. The insulation of each pair of conductors has one colour from each group. The plates forming the body of the connector are of different colours corresponding to the colours of the second group, plate 22a being blue, plate 22b orange &c., and alternate cells in each of these plates are occupied by contacts connected to a conductor having the same coloured insulation. The other cells in each plate are occupied by contacts attached to conductors the insulation colours of which are selected from the first group of colours, and the conductors having these colours are arranged in respective vertical columns. For example, Fig. 19 (not shown), all the conductors attached to contacts in column I are coloured violet, in column III, yellow &c. The stack of plates is sandwiched between two outer plates 28, 29 which are differently coloured to correspond to binder tapes round the cable. The contacts each have one long and one short arm, the long arms projecting from the front surface of the connector to engage between the short and long arms of an identical mating connector. The connectors are mated within a plastic band 23 which has keys 50 to ensure correct insertion of the connectors. During transportation, each connector is inserted in a plastic band and a cover, Fig. 16 (not shown), having appropriate key-ways is inserted into the other end to protect the contacts from dust and corrosion.</p> |
