Assemblies, apparatus, devices and methods useful in providing lightning protection of avionic components associated with aircraft antennas are disclosed. Aspects of the present disclosure may be used on aircraft comprising structural elements made from composite materials having a relatively low electrical conductivity. An exemplary assembly disclosed comprises: an antenna secured to a structural element of the aircraft and configured to receive wireless signals and/or transmit wireless signals external to the aircraft; a communication unit operatively connected to the antenna for signal transmission between the antenna and the communication unit; and an isolation transformer electrically disposed between the antenna and the communication unit where signal transmission between the antenna and the communication unit is conducted via the isolation transformer.

Overcurrent circuits are disclosed for preventing overcurrent in shielded coaxial communication cables. A shield breaking element of an overcurrent circuit is adaptable to be coupled in series with a shield conductor of a shielded coaxial cable, and is also configured to open upon conducting a first electrical current that exceeds an overcurrent threshold, thereby preventing the first electrical current from flowing through the shield conductor of a shielded coaxial cable. A signal breaking element of the overcurrent circuit is adaptable to be coupled in series with a signal conductor of the shielded coaxial cable, and is configured to open when the shield breaking element opens thereby preventing a second electrical current from flowing through the signal conductor. Systems and devices that use the overcurrent circuits, for example, to provide alerts and status, are also disclosed.

A coaxial connector and a method for manufacturing such a coaxial connector. The coaxial connector includes: a conductive core; a metal shielding surrounding the core; a dielectric arranged between the core and the shielding to insulate them electrically with respect to one another; and a shunt to supply a resistive bridge between the core and the shielding. The shunt includes: a graphite element positioned between the core and the shielding; and a first and a second metal deposit to supply an electrical and mechanical connection between the graphite element and respectively the core and the shielding. A coaxial cable and an electrical device can both include such a coaxial connector.

A high frequency electronic connector is formed by a first connector and a second connector. The first connector has a first body and at least one first terminal, and the first terminal is built in the first body. The second connector has a second body and at least one second terminal, and the second terminal is built in the second body and provided for inserting and connecting the first body.
