Abstract

1406161 Two-part couplings HUGHES AIKCRAFT CO 2 April 1973 [3 April 1972] 15691/73 Heading H2E An electrical connector with at least one bore within the connector body, wherein there is disposed an electrically conducting part, which has disposed thereabout an elastomeric sealing device, in contact with the surface of the bore, which inhibits fluid flow into the bore, and comprises a tubular portion and a bent back portion extending therefrom so as to form a onesidedly open annular hollow space therebetween said tubular portion being in sealing contact with the conducting part, and said bent-back portion being in sealing contact with said surface of the bore and being bent back toward the surface so that the annular hollow space is open toward the connector body surface. Pin connector body 70 of, e.g., rigid plastics, comprises through bores 82 containing connector pins 90 which make electrical contact with mating portions 104 of socket connectors 92 disposed in bores 84 of socket connector body 76. Pin and socket connectors 90 and 92 are engagingly fitted by means of resilient collars 94, 96 engaging shoulders 86, 88 in bores 82, 84, respectively, and are sealed identically by seal 150 which includes tubular end-portion 154, radially extending flange 158, which is bent and compressed on insertion into the bore 82 from rear face 74 and resiliently engages the inner walls thereof thus forming a pressure-sensitive seal, socket gripping front portion 162, such that internal recess 166 fits over and engages collar 138 on the connector and internal flange 170 engages in recess 146 in the connector. The end of an insulated conductor 114, 116 is bored and its conducting end soldered or crimped within the internal recess 110, 112 of connector 90, 92. Interface seal 180 has two end resilient flanges 184, 186 which deform on being forced into bores 82, 84, respectively; and also includes reinforced portions 188, 192, 190.
