1,188,548. Electric couplings. WESTERN ELECTRIC CO. Inc. 28 June, 1967 [18 July, 1966], No. 29847/67. Heading H2E. [Also in Division H1] The plug 24 supporting the flexible conductor 22 connecting the circuit elements 14 on either side of a printed-circuit board 10, as described in Specification 1,086,093, is made of a plastics material exhibiting the property of plastic memory, such as a polyolefin or polyethylene. Prior to its insertion in the aperture 16 in the printed-circuit board the plug has its diameter reduced by irradiating or heating and stretching it longitudinally and then freezing it. After insertion heat is applied to increase the diameter of the plug again and thus urge the conductor against the inner surface of the aperture so as to fill it completely. The conductor 22 is then connected to elements 14 by means of solder 28. Instead of a conductive braid a sinuous or helically wound conductor can be employed. |
