Underwater Electronics Connector and Methods

Abstract

An underwater connection system and methods can include a male connector having a proximal end and a distal end and a female connector having a proximal end and a distal end. At least one of the male connector or the female connector can have an increasing taper when viewed in top plan, from a minimum width at its distal end to a maximum width at its proximal end. To do this, the male or female connector can be formed with a surrounding rubber housing. The rubber housing can be formed with a wedge that is integral to the rubber housing to establish the increasing taper. The taper can be linear or curved, according to the needs of the user, and either or the male connector or female connector can be inline or right-angle connectors, according to the system design and space constraints.

Description

FIELD OF THE INVENTION

The present invention pertains generally to electrical connectors. More specifically, the present invention pertains to underwater electrical connectors. The invention is particularly, but not exclusively, useful as an underwater electrical connector with structure that can facilitate disconnection after the connectors has been assembled for an extended time, while at the same time maintaining a minimum profile for the connector.

BACKGROUND OF THE INVENTION

Underwater electrical/electronics connectors (in the specification, the terms “electrical” and “electronics” are interchangeable and can be taken to mean the same thing) can be essential for transmitting power and data across dry, flooded, and water exposed sections of underwater equipment. Low profile, right angle and inline, wet mateable underwater connectors can be used in cases where clearance is limited, or where low system volume or small connector profile is a requirement. These types of connectors can be simple to assemble and deploy.

Although these types of connectors can be simple and easy to deploy, they are often not so simple and easy to retrieve. Disassembly of the male and female ends of this type of connector that have previously been deployed underwater or that have been connected for long periods of time tend to be very difficult to separate, as there can be minimal surface area to hold on to. Additionally, marine growth may have fouled the connector, which can make it difficult to grip the connector for separation.

Still further, the exteriors of both the male and female sides of the connector can be manufactured from smooth rubber, which can prevent the operator from being able to separate the two parts. When the connector is stuck, operators will often wrongly use a flat screw driver to pry the ends of the connector apart. This could easily damage the connector body. In the case of right angle connectors, improper disassembly can result in putting a torque on the body of the connector or rotating the seal and threads, which rigidly fasten the connector and create a watertight seal.

In view of the above, it is an object of the present invention to provide an underwater electrical connector having structure that can prevent the operators finger's from slipping off the connector during disassembly. Yet another object of the present invention is to provide an underwater electrical connector that can provide the operator with an improved surface for disassembling the male and female ends of the connector. Still another object of the present invention is to provide an underwater electrical connector that, in the case of right angle connectors, can allow the operator to rotate the seal and threads of the connector with sufficient torque to create a watertight seal for the connector. Another object of the present invention is to provide an underwater electrical connector that allows for disassembly without the use of tools. Yet another object of the present invention is to provide an underwater electrical connector having structure that facilitates disassembly, while at the same time only minimally increasing the overall profile of the connector body. Another object of the present invention is to provide an underwater electrical connector that can be easy to manufacture and use in a cost-efficient manner.

SUMMARY OF THE INVENTION

An underwater connection system and methods can include a male connector having a proximal end and a distal end, and a female connector having a proximal end and a distal end. At least one of the male connector or the female connector can have an increasing taper when viewed in top plan from a minimum width at its distal end to a maximum width at its proximal end. To do this, the male or female connector can be formed with a surrounding rubber housing. The rubber housing can be formed with a wedge that is integral to the rubber housing to establish the increasing taper. The taper can be linear or curved, according to the needs of the user, and either or the male connector or female connector can be inline or right-angle connectors, according to the system design and space constraints.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring initially to FIGS. 1-3, an improved underwater electronics connection system according to several embodiments of the present invention is shown and is generally designated by reference character 10. As shown in FIGS. 1-3, system 10 can include a male connector 12 with a proximal end 14 and distal end 16, and a female connector 18 having a proximal end 20 and a distal end 22.

Either of the male connector 12 or the female connector 18 can be formed with a decreasing wedge 24, as shown in FIGS. 1-3. With this configuration, the male connector can have an increasing taper when viewed in top plan from a minimum width w₁ at distal end 16 to a maximum width w₂ near proximal end 14. Similarly, female connector 18 can have an increasing taper when viewed in top plan from a minimum width w₁ at distal end 22 to a maximum width w₂ near proximal end 20.

The wedge 24 can be attached to rubber housing 26 using glue or other means known in the art, or alternatively rubber housing 26 can be manufactured so that wedge 24 is integral to the housing (i.e. the connector itself can have the increasing taper when viewed in top plan. The wedge 24 has be formed so that the taper is linear, as shown in FIGS. 1-5, or the wedge can be curved or arcuate when viewed in top plan (not shown in the Figs.), or have any other ergonomic contour when viewed in top plan, according to the needs of the user. As shown in FIGS. 1-3, the rubber housing 26 can surround the electrical structure 28, to protect the electrical portion of the system 10 from the elements.

Referring now to FIGS. 4-5 the system 10 is illustrated when male half 12 is connected to female half 18. When the connected, the wedges 24 can allow for the user to more easily grip the male half 12 and female half 18 to disconnect the two halves 12, 18. At the same time, the overall profile for the system 10 remains minimized, in the event there is not a lot of clearance at the location where the connection is to be established. As shown in FIGS. 1-5, the male connector 12 can be an inline connector (cord 30 is inline with the electrical structure 28), while the female connector 18 can be a right angle connector 14 (cord 30 is at right angles to the electrical structure). It should be appreciated, however, that either or both of the male connector 12 or female connector 18 could be inline connection systems or right angle connection systems, according to the clearance constraints and the needs of the user.

Referring now to FIG. 6, a block diagram 40 can be used to describe the methods of establishing an underwater electrical connection for the present invention according to several embodiments. As shown, method 40 can include the initial step 42 is establishing an increasing taper on male connector 12. The taper can establish a minimum width w₁ at distal end 16 of male connector 12 and a maximum width w₂ near proximal end 14 of male connector 12, as described above. Next, the step of establishing an increasing taper on female connector 18 can be accomplished, as shown by box 44 in FIG. 6. When this step is accomplished, female connector 18 can have an increasing taper when viewed in top plan from a minimum width w₁ at distal end 22 to a maximum width w₂ near proximal end 20, as also described above. Finally, the methods can include connecting male connector 12 to female connector 18, as shown by step 46 in FIG. 6.
