Environmentally sealed electrical connector
First Claim
1. An electrical connector which is sealed in a weather tight condition in both the mated and unmated conditions, said connector comprising:
- a plug member including a housing having a mating face on one end, a plurality of contact receiving bores passing through said housing and opening onto said mating face, a like plurality of contacts each connected to a respective one of a plurality of conductors of a cable and received in a respective one of said bores with said contact directed towards said mating face, first sealing means covering said mating face of said connector, said first sealing means having a like plurality of normally closed slots each positioned in alignment with a respective one of said bores and said contacts, and second sealing means at the other end of said member effecting a fluid tight seal between said cable and said plug member;
a receptacle member including a plug member receiving recess closed at one end by a contact receiving block with a mating face directed inwardly of said recess, a plurality of contact receiving bores in said block leading to said mating face, a sealing assembly mounted for reciprocal movement in said recess, said sealing assembly including a sealing diaphragm having an outer periphery in wiping engagement with the inner periphery of said plug member receiving recess and a plurality of normally closed slots therein each disposed above a respective one of said contact bores, a rigid support plate having apertures therein aligned with said slots, a spring member attached to said plate and said receptacle housing allowing limited reciprocal movement of said sealing assembly within said recess and a hood extending from said receptacle housing substantially enclosing said plug receiving recess, a slot in said hood extending the length of a bottom portion thereof whereby a buildup of moisture and particles in said hood is prevented; and
latching means adapted to secure said plug member and said receptacle member together in a mated condition and including a detent on one of said members and a latching lever operatively mounted on the other of said members to resiliently engage said detent.

Abstract
A sealed electrical connector is disclosed in which both the plug and receptacle portions are completely sealed from the normal atmospheric environment in both the connected and disconnected conditions. Each of the plug and receptacle members is provided with a normally closed sealing diaphragm extending across the mating ends thereof to protect the contacts enclosed thereby from moisture, dirt, etc. The diaphragms are opened, when the connectors are mated, by the male pin contact which extends through both sealing diaphragms to engage in the female receptacle contact. The subject connector obviates the need for a cover, which must be removed prior to mating the plug into the receptacle, and thus mating of the plug into the receptacle can be accomplished using one hand only.

11. A sealed plug member for an electrical connector, said plug member comprising:
-
a housing having a mating face on one end and at least one contact receiving bore leading to said face and, a groove about the periphery of said housing spaced from said mating face, a like number of contacts each connected to a respective conductor and received in a respective one of said bores directed toward said mating face, first sealing means enclosing said mating face, said first sealing means including a diaphragm portion extending across said mating face and an integral flange portion having an inwardly directed lip engaging in said groove, said first sealing means having a normally closed slot disposed over each said bore, said normally closed slot being in said diaphragm portion, and second sealing means at the other end of said housing effecting a fluid tight seal between said conductors and said housing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
