Abstract: A method of assembling an electrical connector that includes an outer conductor body, an inner conductor and a resilient and deformable insulating sleeve. The method includes providing a bore in the rigid outer conductor body having an inwardly directed substantially annular ridge extending therefrom defining a minimum bore diameter of the outer conductor body. A bore is provided in the insulating sleeve along with a substantially annular recess in the outer surface of the sleeve. The maximum diameter of the insulating sleeve is provided greater than the minimum bore diameter of the outer conductor body when the insulating sleeve is at a rest position. The next step is radially compressing the insulating sleeve to a smaller diameter than at the rest position thereof. Next is inserting the insulating sleeve, while at least partially compressed, into the bore of the rigid outer conductor body to a position in which the rigid outer conductor body ridge is in alignment with the insulating sleeve recess.

Abstract: An electrical connector having inner and outer conductors along with a sleeve therebetween. The outer conductor has an inwardly directed annular ridge adapted to interlock with an annular recess in the sleeve. In order to maintain contact between the recess of the sleeve and the annular ridge of the outer conductor with changes in temperature, the length of the ridge is related to the diameter of the sleeve at each point along the slope of the beveled wall of the ridge by the equation L=D tan .theta.. In a second version of the invention described herein there is an assymetrical connector in which the opposed beveled end walls of the respective body and sleeve are defined by frusto-conic surfaces of cones each having a common vertex preferably disposed on the connector longitudinal axis.

Abstract: An electrical connector having inner and outer conductors along with a sleeve. The outer conductor has an inwardly directed annular ridge adapted to interlock with the sleeve. The sleeve is preferably of teflon. In order to maintain contact between the sleeve and the annular ridge of the outer conductor with changes in temperature, the length of the ridge is related to the diameter of the sleeve at each point along the slope of the end slope of the ridge by the equation L=D tan .theta.. The angle related in the equation is the end bevel angle on the ridge and when this angle is on the order of 45.degree., then the relationship reduces to one in which the length of the ridge is comparable to the diameter of the sleeve in order to maintain contact over a temperature change range.

Abstract: A stub-support arrangement for a coaxial transmission line wherein the line has inner and outer conductors and the stub is in the form f oppositely disposed stubs each having a length of 1/8 wavelength at the center operating frequency or less. One of the stubs is an open-circuit stub and the other is a short-circuit stub. In the case of the stubs being of 1/8 wavelength, the characteristic admittances of the stubs are equal and in the case of the stubs being less than 1/8 wavelength the characteristic admittance of the open-circuit stub becomes larger and that of the short-circuit stub becomes smaller as the physical length of the stub is reduced.

Abstract: An improved rotary joint which is embodied, in a preferred version, in an electrical coaxial rotary connector having relatively rotatable male and female housings defining an outer conductor and means defining an inner conductor. One of the housings carries silver-graphite contacts including an outer annular contact associated with the outer conductor and a centrally disposed disc-like contact associated with the inner conductor. Contact between the contacts of the one housing and conductor points on the other housing is provided by a relatively simple contact means in the form of a first centrally disposed bowed spring washer associated with the disc-like contact and an annular spring washer having a plurality of crest contact locations (waves) associated with the outer annular contact. The spring washers are both constructed of a hard conductor material such as berylium copper plated with, for example, silver and then with a tarnish resisting layer such as rhodium or gold.

Abstract: The waveguide assembly is constructed of interlocked sections of hollow rectangular waveguide which are abutted end to end. In a preferred version the abutted ends of the sections may be interlocked by grooving or dove-tailing the sections along the broad walls of the waveguide in a manner insuring alignment of the broad walls. One of the mated sections has locating tabs extending from its narrow walls. The tabs overlap the narrow walls of the adjacent interlocked section and maintain the narrow walls in alignment by preventing slippage along the dove-tail joint. The dove-tail joint is initially constructed in an open configuration and after annealing, the joint is closed by application of pressure thereto. Either one or both broad wall joints may be closed, and when only one is closed then the opposite joint is initially constructed in a closed position.
