At radio frequencies and in particular those associated with LTE and 4G telecommunications in the region of 1 GHz and above, inherent problems have been found with historically employed interconnections that lead to distortions and impairments to the transmitted signal generically termed PIM. This invention relates to creation of a connector system that separates the mechan cal connection features from the forward and return transmission path components by use of non-conductive connector bodies and WaveWay a carefully shaped constrained linear signal path with low resistance and capacitance mating surfaces limiting parallel path distortions and smoother shapes to limit 3rd harmonic and other distortions and lower pressure contact requirements to provide at least equivalent PIM performance to conventional connectors at lower frequencies 800 MHz and improved PIM performance at 1 GHz and above.

A fitting for use with a cable contained in a corrugated metal tubing, the fitting including an adaptor having an internal, longitudinal passage to receive the cable; a body coupled to the adaptor; an internal seal positioned between the adaptor and the body, the internal seal radially disposed about the cable; a nut coupled to the body; and a sealing member positioned between the nut and the body, the sealing member for placement in a valley of the corrugated metal tubing to compress a portion of the corrugated metal tubing between the sealing member and the body.

A method of forming a joint between a coaxial cable and, a coaxial connector includes the steps of: preparing a cable having an inner conductor, a dielectric, a corrugated outer conductor surrounding the dielectric layer, and a jacket such that an end of the inner conductor is exposed, an end of the outer conductor is exposed arid is flattened to form a ring devoid of corrugations, and a portion of the dielectric layer is cored out to form a solder chamber between the inner conductor and the ring of the outer conductor; preparing an assembly comprising a coaxial connector comprising an inner contact, a dielectric spacer, and an outer conductor body having a tail, with a solder preform encircling the tail; inserting the tail and solder preform into the solder chamber; and melting the solder preform to create a joint between the ring and the tail.

A coaxial cable-connector assembly comprising: (a) a coaxial cable; (b) a coaxial connector; (c) a rear body; and (d) a coupling nut. The coaxial cable comprises: an inner conductor; a dielectric layer circumferentially surrounding the inner conductor; an outer conductor circumferentially surrounding the dielectric layer; and a jacket circumferentially surrounding the outer conductor. The coaxial connector comprises: an inner contact electrically connected with the inner conductor; an outer body spaced apart from and circumferentially surrounding the inner contact; and a dielectric spacer interposed between the inner contact and the outer body. The rear body has a main section, a rear collet extending rearwardly from the main section, and a front engagement structure that coordinates with the outer body to engage the outer conductor. The nut has a threaded section and a tapered inner surface. Engagement of the nut with a threaded section on one of the rear body and the outer body advances the nut forwardly so that the tapered inner surface of the nut deflects the rear collet to engage the cable jacket.

A method of forming a solder joint between a coaxial cable and a coaxial connector includes the steps of: positioning a solder element between an end of an outer conductor of the coaxial cable and a connector body of the connector, wherein the connector includes an insulator with a suction passage; lowering the connector body and insulator onto a mounting structure; melting the solder element to form a solder joint between the outer conductor and the connector body, the solder joint including a lower surface formed by contact with the insulator and/or the connector body; and applying suction to the melting solder element from a suction source to reduce the formation of bubbles within the solder joint, wherein a suction path between the suction source and the solder element includes the suction passage in the insulator.

A jumper cable having an end prepared for connecting to a coupling assembly. The prepared end includes an inner conductor, an outer conductor having a helical outer surface contour, and a dielectric core disposed between the inner and outer conductors. A weld washer: (i) threadably engages the helical outer surface contour of the outer conductor, (iii) receives a deformed edge of the outer conductor through an opening in the washer, and (iv) is penetration welded to deformed edge of the outer conductor. Operationally, the face of the weld washer augments the flow of electrical current to electrically ground the outer conductor to the coaxial cable connector.

An assembly includes: a cable; a first connector attached to the cable; a second connector that mates with the first connector to form an interface; a sealing boot that encloses the interface, the sealing boot including a cable section that fits conformably over the cable; a conduit that circumferentially overlies a portion of the cable adjacent the first connector, the conduit including a plurality of first corrugations; and a protective cover that overlies the corrugations of the conduit and the sealing boot, the cover including at least one second corrugation on an inner surface thereof that interdigitates with one of the first corrugations.
