Definitions
- the connector assembly includes two mateable halves wherein the contacts of one half or both halves are immersed in an oil bath.
- the mateable halves are designed so that, after mating, the contacts of each respective half are immersed in a common oil bath.
- Both halves of the connector assembly are connected to resiliently deformable plastic cable conduits that contain a nonconducting fluid which when submerged in water, to any depth. is pressurized to ambient pressure thereby eliminating any differential pressures across the fluid-tight seals in the connector assembly.
- This invention relates to sealed. water-tight electrical connectors and in particular to connectors and connector assemblies which may be coupled or uncoupled under water at any depth without exposing electrical contacts to the water and thereby eliminating the need for disconnecting the electrical power from the attached cables.
- This invention is more particularly related to a disconnectable underwater electrical connector and cable assembly that is capable of withstanding pressures up to at least 2.500 PSlG without failure.
- Disconnectable underwater electrical connector assemblies generally consist of two connector halves that are mateable. each of which including some type of sealing means to prevent sea water from entering the electrical connector when mated and/or separated.
- the limitation on the effectiveness of the connectors assembled or disassembled is a function of the effectiveness of the sealing means, i.e. as the sealing means is subjected to greater and greater differential pressures when it is lowered into water. it is more prone to failure and, in fact. does fail when a differential pres sure exceeds the sealing capacity of the sealing means, usually.
- underwater connector devices use interference-type fittings and ring type sealing members to prevent the entrance of liquid into the electrified portion of the mated connectors.
- a further disadvantage of a connector built in accordance with the teachings of the Pfister patent is that the surfaces that engage the 0" ring to form the fluidtight seals are exposed and therefore subject to damage from external sources. Any scratches and/or dents in the sealing surface results in a bad seal with the 0 ring which will further result in leakage and failure of the connector.
- This invention provides an underwater electrical connector and cable assembly capable of being mated under water, at any depth, without failure because of the elimination of differential pressures across the sealing means of the connector.
- the invention is an underwater electrical connector/- cable assembly characterized by a resiliently deformable cable conduit 300 containing an electrically nonconducting fluid that fills the voids within the conduit and the electrical connector so that when the assembly is submerged. to any dpeth, no differential pressures of any significance arise between the outside and the inside of the connector and cable assembly.
- the underwater electrical connector and cable assembly comprises: a housing having a forward mating end 102 a rear conduit receiving end 104 and a central axis from said forward end to the rear end; a plurality of electrical contacts having a mating end 112 and a conduc' tor receiving end 114', means for mounting 123 the electrical contacts 110 in spaced relationship around said housing central axis so that the mating ends 112 of said contacts 110 are at the mating end 102 of said housing 100'.
- said sealing means including a forwardly biased 122 portion 121 that covers the mating end 112 of said contacts 110 and maintains the fluid-tight seal when the contacts 110 are covered and is rearwardly movable upon mating with a receptacle 200 to expose the contacts 110 and engage corresponding receptacle contacts 210.
- said covering means 121 defining with said housing 100 a cavity within which at least a portion of the mating ends 112 of the electrical contacts 110 are disposed.
- the cavity 120 communicating with the rear conductor receiving cavity poriton of the housing 100; a water-tight resiliently deformable conduit 300 connected to the conduit receiving end 104 of the housing 100, the conduit 300 including therein a plurality of electrical conductors 400 connected to the respective conductor receiving ends 114 of said contacts 110; and electrically nonconducting fluid filling the remaining space in said conduit 300 and said housing cavities 120. 140, whereby the mating ends 112 of said electrical contacts 110 are substantially surrounded by said nonconductive fluid, said forward mating end 102 of said housing 100 adapted to receive within said housing 100, in fluid tight relationship.

- the plug portion of the assembly includes a housing 100 having a forward mating end 102 and a rear conduit receiving end I04.
- a resiliently deformable conduit 300 e.g. made from an elastomer is attached to the conduit receiving end I04 to form a fluid-tight seal.
- a plurality of electrical contacts 110 having a forward mating end I12 and a rear wire receiving end 114 are mounted in a circumferential manner and in spaced relationship around the central axis of the housing I23.
- the contacts are mounted within a generally tubular housing 123 that has telescoped therein a second generally cylindrical housing 121 that is forwardly biased by a spring 122 to a first contact covering position.
- the generally cylindrical inner housing I2I in its forward biased and contact covering position is in pressure contact with 0" rings I70 to form a fluid-tight seal between the outer tubular housing I23 & inner cylindrical housing I21, thereby protecting the contacts 0 and their forward mating ends I12 from coming into contact with external fluid.
- All voids I20, I40 within the housing I00 and resiliently deformable conduit 300 are filled with a nonconducting fluid. such as mineral oil.
- a nonconducting fluid such as mineral oil.
- the fluid in the housing I00 and cable 300 communicating with the mating ends 112 and ocnductor receiving ends 114 of the contacts and with the wires 400 in the conduit 300 so that. at all times, the mating ends N2 of the contacts are immersed in the nonconducting fluid.

- Mounted within the receptacle housing 200 are a plurality of electrical contacts 210 circumferentially arranged around the central axis of cylindrical housing 221 in the same spaced relationship as the corresponding plug contacts 110.
- the inner cylindrical housing 221 which is telescoped within the outer tubular housing 223 forms a fluid-tight seal at the front of the receptacle with tubular housing 223 by means of "0 rings 270.
- the outer tubular housing 223 is forwardly biased by a spring 222 which maintains the 0" ring 270 in pressure contact with the wall of inner housing 221, thereby assuring a fluid-tight seal and protecting the electrical contacts 210 from exposure to sea water when the receptacle is immersed therein.
- the tubular housing 223 is rearwardly movable upon the application of a rearward force supplied to the front end of the tubular housing 223.
- the 0" ring 270 maintains a fluid-tight seal along the outside of the cylindrical inner housing 221.
- the cylindrical housing 22] generally comprises a smooth rod of insulating material with the matching ends 2I2 of the contacts flush with the surface of the housing 221. All the voids within the conduit 300 and the connector housing 200 are filled with a nonconducting fluid and the 0" rings 270 maintain a fluid-tight seal between the fluid within the connector assembly and conduit and the water in which the assembly is immersed.
- FIG. 2 illustrates the connector assembly in its mated position.
- the receptacle tubular housing 223 is forced rearwardly of the receptacle housing 200 and the cylindrical housing 121 of the plug assembly I00 is forced rearwardly with respect to housing so as to allow the receptacle contacts 210 to mate with the plug contacts at their respective mating ends 2l2, I I2.
