Description

Method of twisting electrical wires.
The present invention relates to a method of twisting a plurality of electrical wires each fixed to an electronic component.
The assembly of electronic goods often requires many different electronic components to be fitted to a ready-made housing. Many components, such as cooling fans, are often fitted inside the housing before being connected or soldered to an electronic circuit board. It is common for many of the electronic components to be supplied by third-party suppliers, and as a result of this the components are not always in the most suitable form for direct fitting into the housing.
Such a problem exists with certain electronic components, such as cooling fans, which arrive from the manufacturers with the wires carrying power to the unit connected to the component at one end and being free at the other. For assembly purposes to ensure neatness and fitting to suitable cable ducting within the housing, the wires need to be twisted together so that the two or more separate wires become one twisted 'rope'. This one twisted 'rope' can then easily be fitted into the wire ducting within the housing, or can be easily and tidily routed as required.
An object of the present invention is to provide a method for twisting a plurality of wires together.
According to the present invention, there is provided a method of twisting a plurality of substantially parallel insulated electrical wires, each fixed to an electronic component at one end and free at the other, the method comprising the steps of: clamping the plurality of wires at a predetermined point between the component end and the free ends; and rotating the clamp a predetermined number of times so as to twist the wires only between the predetermined point and the electrical component.
By providing that the wires do not twist completely up to the free end, enough room can be allowed for the ends of the wires to be run to terminals where they can be soldered or connected once the component and the twisted 'rope' have been mounted in the housing.
The invention will now be described by way of example with reference to the accompanying drawings, in which: Figure 1 is a diagram showing a first apparatus which can be used to implement the present invention; Figure 2 is a diagram showing the side elevation of a second apparatus which can be used to implement the present invention; and Figure 3 is a diagram showing two wires that have been twisted together using the present invention.
Figure 1 is a diagram showing a first apparatus which can be used to implement the present invention. The apparatus consists of a shaped main body 13 as shown. At one end of the apparatus is a cylindrical post 10 which is designed for insertion into the chuck of a drill or similar rotary drive tool. A clamping device 11 is attached to the apparatus by way of a flexible attachment 12 which allows the clamping device 11 to be positioned precisely onto the main body 13.
The function of the apparatus is as follows. The individual wires which are required to be twisted are inserted into the apparatus from the top end. The length of the wires that is required to be left untwisted is then bent back over the apparatus and is heid in place by a clamping device 11. The main body 13 is specially shaped to allow easy insertion and clamping of the untwisted wires. By bending the untwisted wires around the specially shaped section it allows the clamping device to firmly grip the wires during the twisting operation. This reduces the likelihood that the wires will slip during the twisting operation, and also allows the clamping device to use weaker springs thus facilitating the operation of the apparatus. The cylindrical post 10 is then inserted into the chuck of a drill, or similar rotary drive tool, and the whole apparatus is turned whilst the component to which the wires are attached is held stationary. The apparatus is rotated a number of times until the required level of twisting has been achieved. The clamping device 11 is then removed and the untwisted end of the twisted rope released from the apparatus.
Figure 2 is a diagram showing the side elevation of a second apparatus which can be used to implement the present invention. In this embodiment, the clamp 20 is an integral part of the rotator unit and is spring mounted to the main body 23 by way of springs 21. To clamp the wires that are to be twisted the clamp 20 is lifted away from the main body 23 of the apparatus and the required length of the wires is inserted between the clamp 20 and the main body 23 of the invention. The clamp 20 is then released and, due to the way it is spring mounted, clamps the wires in place.
A cylindrical post 22 forms part of the main body 23 and is designed for insertion into the chuck of a drill or similar rotary drive tool The apparatus is then rotated a number of times until the required amount of twisting has been achieved. The clamp 20 can then be lifted up and the wires removed from the twisting apparatus.
Figure 3 is a diagram showing two wires that have been twisted together using the present invention. Two wires 31 and 32 are connected to electronic component 30. The wires have been twisted along the length of section 35 and remain untwisted along section 34. The free ends of both wires can then be easily attached to terminals where they can be soldered or connected once the component and the twisted 'rope' have been mounted in a housing.

Claims (4)

1. A method of twisting a plurality of substantially parallel insulated electrical wires, each fixed to an electronic component at one end and free at the other, the method comprising the steps of: clamping the plurality of wires at a predetermined point between the component end and the free ends; and rotating the clamp a predetermined number of times so as to twist the wires only between the predetermined point and the electrical component.
2. The method of claim 1, further comprising leaving an untwisted section of the wires between the predetermined point and the free ends.
3. The method of claims 1 or 2, further comprising rotating the clamp by way of a rotary driver.
