An electrical connector that comprises an outer conductive shell supporting at least one signal contact therein and that includes a front end for mating with a mating connector and a back end opposite the front end for electrically connecting to a printed circuit board or a coaxial cable. A primary ground connection is located either inside or outside of the outer conductive shell. The primary ground connection is configured to electrically engage the mating connector with the printed circuit board or with the coaxial cable. A secondary ground connection is located either inside or outside of the outer conductive shell. The secondary ground connection is configured to electrically engage the mating connector with the printed circuit board or with the coaxial cable.

An RF Connector and grounding device therefor comprises a driver, a contact ring and a spring clamp having a split ring washer disposed therebetween. The split ring washer interposes the driver on one side of the washer and the contact ring on the other side thereof and defines an aperture for receiving a prepared end of a coaxial cable. The washer is connected to one side of an annular ring while a shouldered flange is disposed on the opposing side of the ring. Upon delivering a compressive clamping force to a compression cap, the split ring washer is captured between adjacent peaks or corrugations of the outer conductor.

An electrical plug connector for a coaxial or triaxial cable, wherein the cable includes an internal conductor, a first shielding conductor surrounding the internal conductor and extending coaxially with it, and optionally a second shielding conductor surrounding the first shielding conductor. The plug connector has a connector body, which includes an internal conductor contact element designed as a plug, socket, or coupling, for contacting with the internal conductor, an internal shield contact element provided for contacting with the first shielding conductor, and optionally an external shield contact element provided for contacting with the second shielding conductor. The connector body is configured such that the contact elements in the mounted condition of the plug connector are arranged on the cable such that a maximum diameter of the connector body is less than or equal to the outer diameter of the cable or only slightly larger than the outer diameter of the cable.

A coaxial cable connector system, comprising a coaxial connector, a coaxial cable, and a universal coaxial cable fixing sleeve is provided. The universal coaxial cable fixing sleeve comprises a first gripping component, a second gripping component, and a third gripping component. When the coaxial cable is assembled to the universal coaxial cable fixing sleeve, the first gripping component grips a conductive shield of the cable, and the second and third gripping components grip a protective outer jacket of the cable, respectively. When the universal coaxial cable fixing sleeve is engaged to a first connector, a first housing outer surface thereof corresponds to and fixedly engages with a sleeve receiving inner surface of the first connector, and when disengaged and engaged to a second connector different in type from the first connector, no re-preparation of the cable is required for corresponding fixed engagement.

A contacting device for contacting a shielding conductor of an electrical line with a grounding portion includes: a housing which encloses a receptacle space into which the electrical line including the shielding conductor is insertable, the housing being attachable to the grounding portion such that the grounding portion extends in the receptacle space; and a spring element which is arranged on the housing so as to be pivotable about a pivot axis from an open position into a clamping position, in order, in the clamping position, to contact the shielding conductor of the electrical line inserted into the receptacle space with the grounding portion to which the housing is attached.

A connecting device configured to be installed on a first coaxial cable connector to facilitate connection of the first connector to a second connector and to maintain ground continuity across the connectors. In some embodiments, the connecting device includes a grounding element disposed in a gripping member, the grounding element including one or more projections configured to extend beyond an end of the gripping member to conductively engage an outer surface of the second connector.

An electrical connector that includes an outer conductive shell that encloses at least one signal contact therein and includes a front end for mating with a mating connector and a back end opposite the front end for electrically connecting to a printed circuit board. A primary ground connection is located inside or outside of the outer conductive shell, the primary ground connection being configured to electrically engage the mating connector with the printed circuit board or coaxial cable. A secondary ground connection is located inside or outside of the outer conductive shell and is configured to electrically engage the mating connector with the printed circuit board or the coaxial cable.

A coaxial cable connector includes a body configured to engage a coaxial cable having a conductive electrical grounding property, a post configured to engage the body and the coaxial cable when the connector is installed on the coaxial cable, a nut configured to engage an interface port at a retention force, and a grounding member extending about the nut. The grounding member is configured to increase the retention force between the nut and the interface port so as to maintain an electrical ground connection between the interface port and the nut when the nut is in a loosely tightened position on the interface port.

An electrical connector that has a conductive shell supporting at least one signal contact therein and that has a front end for mating with a mating connector and a back end opposite the front end for electrically connecting to a coaxial cable. A ground connection is located inside of the conductive shell. A coupling member is rotatably coupled to the conductive shell and has an engagement feature for mechanically engaging a support panel associated with the mating connector. A sealing member is disposed on the conductive shell that is configured to provide an environmental seal between the conductive shell and the support panel when the conductive shell is mated with the mating connector.

A RF coaxial cable connector with rapid installation includes a front shell, a rear protective sleeve, a front insulator, a center conductor, a rear insulator, a cable crimping ring, and a cable clamping assembly. The front insulator, the center conductor and the rear insulator are arranged in a front-rear sequence in a cavity of the front shell. The cable crimping ring has a front end surface abutting on an outer ring end surface of a rear end surface of the rear insulator, and is connected with the front shell. The rear protective sleeve is connected with the front shell.
