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 combination structure of a clamping member and a circuit board for a signal connector is disclosed. The clamping member includes two clamping members fixedly connected to two sides of the circuit board. Each clamping member has a pair of first positioning pins and a pair of second positioning pins. Thereby, the center of the guide pin can be guided and the guide pin won't be loosened, so as to improve the stability of the signal and reduce the loss.

A cable connector disposed at a cable includes a signal protection device, an outer pipe and a transmission member. The signal protection device includes an inner pipe and a signal protection module. The inner pipe is inserted into the outer pipe through an end opening thereof such that a metallic conducting rod of the inner pipe is in the outer pipe. The signal protection module is inserted through another end opening of the outer pipe such that the metallic conducting rod of the inner pipe is penetratingly disposed at the signal protection module. The transmission member is inserted through another end opening of the outer pipe such that a conducting element is electrically connected to the metallic conducting rod of the inner pipe, revealing a transmission element. Therefore, the signal protection device is modularized and miniaturized.

A receptacle for receiving a plug connector of a high-voltage cable for a microfocus X-ray tube with a cathode, which has a metal filament and grid cap. The receptacle has a ceramic insulator with three contiguous cavities. The first cavity near the filament includes electrical contacts for the filament and the grid cap. The second cavity includes spring contacts for supplying current to the filament and a center pin for supplying voltage to the grid. The third cavity receives the plug connector. The insulator has a removable grid mounting which is conductively connected to the grid cap of the cathode. The first and second cavities are surrounded in the radial direction by the grid mounting. An air gap extends radially between grid mounting and ceramic body. At the end of the grid mounting remote from the filament is a circumferential groove in the axial direction between the grid mounting and the ceramic insulator.

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.
