Abstract
Abstract A low cost circular sealed connector is disclosed which provides a weather tight seal between two polarized connector halves, namely a plug and a receptacle, when mated. The plug half of the connector is provided with a number of through bores equal to the number of electrical socket contacts to be carried thereby. Each of the through bores has a constricted neck portion serving as a resilient biasing means acting on the socket portion of the contact inserted therein. The receptacle half of the connector has a like number of bores, each with a male contact therein, and a hood portion with an inwardly directed flange on the outer end. The hood portion is preferably initially rolled back upon the receptacle half of the connector, the connector halves are mated and the hood portion is unrolled so that it extends fully over the plug half with the flange seated over the end of the plug. The hood thus serves for both sealing the connector and providing a means whereby rapid visual inspection may be made of the connector to insure proper connection. The subject connector is adapted for use with stamped and formed contacts and may further be provided with a sealing boot to adopt the receptacle half for a weather tight seal with a cable.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
177 words
A circular sealed connector comprising: a plug member having a substantially cylindrical body, a polarized profiled mating portion on one end of said body, an enlarged peripherial projection towards the other end of said body, and a plurality of longitudinal bores through said body, each said bore having a constricted throat portion; a like plurality of female receptacle contacts each inserted into a respective bore of said plug member, said constricted throat portion biasing said contact closed; a receptacle member having a substantially cylindrical body with a polarized profiled mating portion, a cylindrical hood integral with said body extending beyond said mating portion, an inwardly directed annular flange on the free end of said hood, and a like plurality of longitudinal bores through said body, said annular flange of said hood extending over said peripherial projection of said plug member fully mated in said receptacle member to substantially enclose said plug member and form a weather tight seal therebetween; and a like plurality of male pin contacts each mounted in a respective bore of said receptacle member.
Claim 2
Dependent Claim
177 words
A circular sealed connector comprising: a plug member having a substantially cylindrical body, a polarized profiled mating portion on one end of said body, an enlarged peripherial projection towards the other end of said body, and a plurality of longitudinal bores through said body, each said bore having a constricted throat portion; a like plurality of female receptacle contacts each inserted into a respective bore of said plug member, said constricted throat portion biasing said contact closed; a receptacle member having a substantially cylindrical body with a polarized profiled mating portion, a cylindrical hood integral with said body extending beyond said mating portion, an inwardly directed annular flange on the free end of said hood, and a like plurality of longitudinal bores through said body, said annular flange of said hood extending over said peripherial projection of said plug member fully mated in said receptacle member to substantially enclose said plug member and form a weather tight seal therebetween; and a like plurality of male pin contacts each mounted in a respective bore of said receptacle member.
Claim 3
Dependent Claim
33 words
A circular sealed connector according to claim 1 further comprising an alignment rib formed on the exterior each of said members whereby the members can be brought into proper polarized alignment before mating.
Claim 4
Dependent Claim
16 words
A circular sealed connector according to claim 1 wherein said contacts are stamped and formed contacts.
Claim 5
Dependent Claim
20 words
A circular sealed connector according to claim 1 wherein said contacts further include crimp means for clampingly engaging associated conductors.
Claim 6
Dependent Claim
21 words
A circular sealed connector according to claim 1 wherein said plug and receptacle members have not more than 12 bores therein.
Claim 7
Dependent Claim
28 words
A circular sealed connector according to claim 1 wherein said hood is resilient so as to be rolled upon itself to thereby provide access to said mating portion.
Claim 8
Dependent Claim
22 words

A circular sealed connector according to claim 1 further comprising a sealing boot adapted to be mounted on the end of said receptacle opposite said hood, said boot comprising a hollow cylindrical member closed at one end, a central orifice in said closed end, a reinforcing ring at the open end of said member, and an annular hood attached to and extending forwardly of said reinforcing ring, said boot being adapted to have a cable passed through said orifice and to sealingly engage both the cable and the end of said receptacle member opposite said hood.
Claim 11
Dependent Claim
16 words
A circular sealed connector according to claim 9 wherein said boot is formed of rubber material.
Claim 12
Dependent Claim
15 words
A circular sealed connector according to claim 10 wherein said boot is formed of neoprene.
Claim 13
Dependent Claim
20 words
A circular sealed connector according to claim 1 further comprising means for fixedly mounting said receptacle member in a panel.
Claim 14
Dependent Claim
24 words
A circular sealed connector according to claim 12 wherein said mounting means comprises a groove formed about the outer periphery of said receptacle member.
