Abstract

186,526. Ellison, G. Oct. 18, 1921. Contacts of the kind comprising a closed coil helix b of wire mounted so as to have an angular set which renders the coil readily compressible when a plug d is inserted in it or a socket forced around it as described in Speccfication 29822/13 have the angular set produced by a stiff split ring a arranged within the helix b. The diameter of the ring in the case of a contact to be engaged by a plug contact member is slightly greater than the mean diameter of the helix and, in consequence the outer edge of the ring presses upon the convolutions of the wire and gives them a lateral set as shown. In the case of a helix supported internally and engaged by an external contactsocket, the diameter of the ring is slightly less than the mean diameter of the helix.
