Abstract

An electrical connector which has to be mated and unmated remotely, e.g. in a space-ship, uses magnetism to assist in, or even to cause, the mating and unmating. The female element has a high-power bar magnet while the male element has an electro-magnet. The magnets can have their axes parallel to the elements' end faces. Both may be electro-magnets. Horse-shoe magnets or electro-magnets may be used. <IMAGE>

Description

SPECIFICATION Electrical connector This invention relates to an arrangement for the remote mating and unmating of the male and female elements of electrical connectors. One example of the use of such an arrangement is the remote control of an umbilical connector between a satellite or space station and a space vehicle such as a shuttle.
According to the invention, there is provided an arrangement for the remote mating and unmating of male and female connector elements, in which one of said elements is provided with a highstrength fixed magnet adjacent to its mating end while the other of said elements is provided with an electro-magnet or solenoid, in which to assist in the mating the electro-magnet or solenoid is energised such that is polarity is the reverse of the magnet, so that the magnet and the electro-magnet or solenoid attract each other, and in which to assist in the unmating the electro-magnet or solenoid is energised such that the polarity is the same as that of the magnet, so that the magnet and the electro-magnet or solenoid repel each other.
According to the invention, there is also provided an arrangement for the remote mating and unmating of male and female connector elements, in which each said element is provided with an electro-magnet or solenoid, in which to assist in the mating the electro-magnets or solenoids are oppositely energised so that they attract each other, and in which to assist in the unmating the electro-magnets or solenoids are similarly energised so that they repel each other.
An embodiment of the invention will now be described with reference to the accompanying highly schematic drawing, which shows in end on and sectional views the male and female elements of a connector pair embodying the invention.
In one arrangement embodying the invention a high strength bar magnet, made from one of the high permeability magnetic alloys now commercially available is mounted on one connector element so that one of its poles is end on to the end face of that element. The other connector element has an electro-magnet similarly mounted, so that when the elements are mated one pole of one magnet is adjacent to one pole of the other magnet. Thus in the drawing we see a permanent magnet 1 in the female element and an electromagnet's coil 2 in the male element.
To assist in the mating, or in some cases to effect the mating, the electro-magnet is energised in the opposite sense to the bar magnet, so that in the arrangement shown we have a North Pole adjacent to a South Pole. Hence the two magnets attract and pull the two elements together.
To assist in the unmating, or in some cases to effect the unmating, the electro-magnet is energised in the same sense as the bar magnet, so that we have two adjacent North Poles. Hence the two magnets repel and urge the elements apart.
For underwater applications the movable parts can be contained in oil-fitted containers.
Using modern high strength magnet material a bar magnet 1" (2.45cm) long can induce a force of 5.5 pounds (2.495kg) at a distance of 0.25" (0.6325cm). This, with the use of a powerful electro-magnet, gives an adequate force for the present purpose, especially for use in friction less nongravity outer space conditions. Even in normal conditions, the magnets should provide useful assistance to mating and unmating.
It is also possible for the axis of a bar magnet to be parallel to the end face of its connector element, in which case the axis of the electro-magnet is also parallel to the end face of its connector element. Here the use of pairs of poles co-operating should provide an enhanced effect when mating or unmating.
Alternatives to the arrangements described above include the use of horse-shoe magnets and electro-magnets, and the use of suitably controlled electro-magnets in both elements.
1. An arrangement for the remote mating and unmating of male and female connector elements, in which one of said elements is provided with a high-strength fixed magnet adjacent to its mating end while the other of said elements is provided with an electro-magnet or solenoid, in which to assist in the mating the electro-magnet or solenoid is energised such that its polarity is the reverse of the magnet, so that the magnet and the electro-magnet or solenoid attract each other, and in which to assist in the unmating the electro-magnet or solenoid is energised such that the polarity is the same as that of the magnet, so that the magnet and the electro-magnet or solenoid repel each other.
2. An arrangement as claimed in claim 1, in which the permanent magnet is a bar magnet and the electro-magnet is also of the bar type, and in which the axes of the magnet and of the electromagnet are designed with the axes of the connector elements.
3. An arrangement as claimed in claim 1, in which the permanent magnet is a bar magnet and the electro-magnet is also of the bar type, and in which the axes of the magnet and of the electromagnet are parallel to the end faces of the connector elements.
4. An arrangement as claimed in claim 1, in which the permanent magnet is a horse-shoe magnet with its two pole ends adjacent to the end face of its connector element, and in which the electromagnet is of the horse-shoe type with its pole ends adjacent to the end face of its connector element.
5. An arrangement for the remote mating and unmating of male and female connector elements, in which each said element is provided with an electro-magnet or solenoid, in which to assist in the mating the electro-magnets or solenoids are oppositely energised so that they attract each other, and in which to assist in the unmating the electro-magnets or solenoids are similarly energised so that they repel each other.
