1294701 Two-part couplings G & H TECHNOLOGY Inc 7 Nov 1969 [8 Nov 1968] 54670/69 Heading H2E Two parts 12, 14 of a connector 10 are locked together so as to be quickly releasable by axial movement only of a keeper sleeve 116 on the part 14, the movement being produced by hand or by means of a lanyard or an actuator package. In order to engage the parts 12, 14, the keeper sleeve 116 is pulled rearwards, compressing a spring 122 and allowing resilient segmental fingers 90, which are attached to a pilot sleeve 124 on the part 14, to move radially outwards so that the forward tip of the keeper sleeve 116 becomes latched behind outwardly facing shoulders 130 on the fingers 90. The parts 12, 14 are then aligned with the aid of a polarizing key and keyway so that the pilot sleeve 124 enters a corresponding annular recess 126, and the fingers 90 are moved axially forwards by means of their collar 94 until their tips 110 pass over a peripheral shoulder 112 on a metal shell 16 of the part 12. The keeper sleeve 116 is then automatically released and is urged forward by the spring 122 to lock the finger tips 110 behind the shoulder 112. In the connected state, a fluid-tight seal is ensured by a silicone rubber gasket 68 which is kept under compression between connector faces 36, 36<SP>1</SP> by a spring 104. An indicator mark 142 on metallic shell 18 of the part 14 is hidden by a finger collet 96 when the parts are fully engaged. The connector parts are released by moving the keeper sleeve 116 rearwards, allowing the finger tips 110 to clear the shoulder 112. Further rearward movement of the sleeve 116 causes its rear face 132 to contact a stop 134 on the collar 94, and the consequent movement of the latter causes a finger flange 92 to abut a shoulder 102 on the shell 18 and to separate the shell 18 from the shell 16. The shell 16 contains an assembly 22 of electrical socket contacts 58 connected to wires 38<SP>1</SP> and mating with a corresponding assembly 24 of pin contacts 34 in the shell 18. Electrical continuity between the shells is ensured by a flexible metallic ring 74 which bridges the gasket 68 and bears on a silver ring 82 welded to the end of the shell 18.
