Abstract

725,021. Two-part couplings. TITEFLEX, Inc. April 23, 1953 [May 7, 1952], No. 11287/53. Class 38 (1). A multiple-contact plug and socket connecter comprises metal shells 13, 16 housing respectively insulating cores 68, 28, at least one of which is resilient and slidable in its shell. Core 68 houses sockets 76 in bores, a portion of the core projecting into shell 28 in the engaged position and into abutting engagement with core 28 which houses pins 39, the end face of core 68 carrying an annular rib 78 which forms a seal. The outer ends of the bores in each core are conical to receive resilient plugs 44 which surround the wires 43 leading to the contacts, spring-pressed plates 51 bearing on the outer ends of plugs 44 to compress them onto the wires and also maintain pressure on the seal between the inner faces of the cores through the slidable core or cores. The springs are compressed by nuts 60 engaging the ends of the shells and acting through fittings 54 connected to screens 53 on the cables. The shells are held in engagement by a nut 17 and additional seals are provided by rings 36 located between the cores and shells. The cores are prevented from rotating in the shells by keys 34 and the shells are orientated by a key 72 engaging a keyway 71 in core 68.
