Abstract
Abstract A sealed connector which can be used for making electrical connection underwater. The connector comprises two chambers one behind the other, the inner chamber containing an electrical connection terminal and being closed by a first diaphragm penetrable by a plug contact, the outer chamber being closed by a second diaphragm also penetrable by the plug contact, both chambers being filled with an electrically insulating grease, jelly or similarly viscous liquid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
A connector comprising an outer casing, first wall members defining a first chamber in the casing, at least one connection terminal within the first chamber, a first diaphragm closing the first chamber, second wall members defining a second chamber behind the first diaphragm a second diaphragm closing the second chamber, each diaphragm having an aperture openable by a plug plugged into the connector terminal and penetrating both diaphragms, both chambers being adapted to be filled with an electrically insulating grease, jelly or similarly viscous liquid.
Claim 2
Dependent Claim
85 words
A connector comprising an outer casing, first wall members defining a first chamber in the casing, at least one connection terminal within the first chamber, a first diaphragm closing the first chamber, second wall members defining a second chamber behind the first diaphragm a second diaphragm closing the second chamber, each diaphragm having an aperture openable by a plug plugged into the connector terminal and penetrating both diaphragms, both chambers being adapted to be filled with an electrically insulating grease, jelly or similarly viscous liquid.
Claim 3
Dependent Claim
75 words
A connector comprising a casing, having a hollow interior, an insulating support member within the casing, a connection terminal supported by and projecting from both sides of the support member, and, on each side of the support member, first and second flexible diaphragms, each diaphragm defining an aperture penetrable by a plug inserted into the connector from either side, the casing being adapted to be filled with a non-electrically-conducting grease, jelly or similarly viscous liquid.
Claim 4
Dependent Claim
75 words
A connector comprising a casing, having a hollow interior, an insulating support member within the casing, a connection terminal supported by and projecting from both sides of the support member, and, on each side of the support member, first and second flexible diaphragms, each diaphragm defining an aperture penetrable by a plug inserted into the connector from either side, the casing being adapted to be filled with a non-electrically-conducting grease, jelly or similarly viscous liquid.
Claim 5
Dependent Claim
33 words
A connector according to claim 1, wherein the casing has a fluid access port for purging the casing with a non-electrically-conducting grease, jelly or similarly viscous liquid between the first and second diaphragms.
Claim 6
Dependent Claim
15 words
A connector according to claim 3 comprising a second fluid access port in the casing.
Claim 7
Dependent Claim
11 words
A connector according to claim 3 wherein said port is valved.
Claim 8
Dependent Claim
16 words
A connector according to claim 5 wherein the valved port has means to close it down.
Claim 9
Independent Claim
89 words
A method of connecting a plug to a connector which comprises a connection terminal housed in a casing closed by first and second diaphragms axially one behind the other in the casing, the casing being filled with non-electrically-conducting viscous liquid, the method comprising the steps of: inserting the plug terminal through the second diaphragm, but not through the first; purging the casing between the first and second diaphragms with the viscous liquid under pressure; and inserting the plug further to penetrate the first diaphragm and engage the connection terminal.
Claim 10
Independent Claim
89 words
A method of connecting a plug to a connector which comprises a connection terminal housed in a casing closed by first and second diaphragms axially one behind the other in the casing, the casing being filled with non-electrically-conducting viscous liquid, the method comprising the steps of: inserting the plug terminal through the second diaphragm, but not through the first; purging the casing between the first and second diaphragms with the viscous liquid under pressure; and inserting the plug further to penetrate the first diaphragm and engage the connection terminal.
Claim 11
Dependent Claim
14 words
A method as claimed in claim 7, wherein said steps are carried out underwater.
