Abstract
Coaxial connecting devices used for transmitting high frequency electrical signals having two connector elements of generally cylindrical profile, and wherein each of the connector elements has an inner conductor, an insulator, and an outer conductor. In one of the two connector elements that may be of a male or a female orientation has two canted coil spring contacts where at least one of a first spring contact can be retained within at least one first spring groove within a second inner conductor and at least one of a second spring contact is retained within at least one second spring groove within a second outer conductor. The at least one second spring contact can be used as a simultaneous EMI shielding contact and latching, locking, or both latching and locking device.
Claims19
A high frequency connecting apparatus comprising:
- a first connector element comprising an inner conductor, an outer conductor and an insulator separating the inner conductor from the outer conductor;
- said insulator fitted radially in between the inner conductor and the outer conductor, wherein said inner conductor comprises a male tip;
- a second connector element comprising an inner conductor, an outer conductor, and an insulator separating the inner conductor from the outer conductor, said insulator fitted radially in between the inner conductor and the outer conductor, wherein the inner conductor comprises a female tip comprising a bore for receiving the male tip;
- a groove on the outer conductor of the first connector element and a groove on the outer conductor of the second connector element capturing a canted coil spring contact therebetween to provide simultaneous EMI shielding and engagement structure to engage the first connector element to the second connector element;
- and
- wherein the female tip comprises a slotted socket or a groove holding a spring contact.
A method of manufacturing a high frequency connecting apparatus comprising:
- forming a first connector element, said first connector element comprising an inner conductor, an outer conductor and an insulator separating the inner conductor from the outer conductor;
- said outer conductor comprising a base and an annular side extending from the base;
