Definitions
- each of the coaxial cables comprises an inner conductor, a dielectric insulator surrounding the inner conductor and a shield surrounding the dielectric insulator. It has been found that a construction of this design allows the use of coaxial cables with adequate electrical properties for the application whilst the jacket ensures that the cable has sufficient mechanical stability to withstand multiple extensions and also to have sufficient resilience to provide a sufficient memory effect, i.e. returns to its original (unextended) position.
- the jacket can be made from a variety of materials such as material selected from the group of polymers comprising polyester, polyurethane, polyethylene and polyvinylchloride. Tests have shown that the best material for ensuring sufficient resilience has a Shore hardness of 36D. In one preferred embodiment of the invention this is achieved by using a polyurethane for the jacket.
- the coaxial cable is provided with a protective layer about the shield to which the jacket is attached.
- This protective layer serves to provide sufficient mechanical stability and resiliency.
- the protective layer is made from polyimde.
- the antenna 20 can be extended by 100 mm.
- the dimensions of the cable storage department 50 are approx. 14 mm x 14 mm. However, these dimensions are not limiting of the invention.
- this invention is described with respect to a mobile telephone 10, it should be noted that it can also be used in any apparatus in which an extendible cable is required. Examples of such apparatus include radios and walky-talkies.
- the invention may also find application other areas such as mini-robots or sensors such as position sensors, temperature sensors or marking sensors.
