A coaxial cable distributor, wherein three or more junction plugs () are fitted to the surface of a casing () having a hollow therein, the external contacts of the junction plugs () are electrically connected to each other through the casing (), the center contacts of the junction plugs () are electrically connected to each other in the hollow of the casing (), and at least two of the junction plugs () are rotated about the rotating axis in a direction orthogonal to the projected direction thereof from the surface of the casing () while maintaining the electrical connection between the external contacts and between the center contacts.

Coaxial cable distributor

A novel leakage radiation preventing element effectively prevents radio waves from being radiated from an electronic appliance, without depending upon a capacitor or a choke coil. The leaked current I.sub.os and I.sub.or generated from a hole or a gap formed in a casing or a chassis is introduced into a wave guide path and then attenuated by radio wave absorption function of a magnetic substance disposed therein. A coaxial conductor (2) is passed through a hole (107) formed in a chassis (3). The wave guide path (104) is formed between the chassis and a conductive disk (101) electrically floated from the chassis. A radially outward end of the wave guide path (i.e., the outer circumferential end of the conductive disk) is shorted to the chassis at high frequency, and further the inside of the wave guide path is filled with a ferrite ring (102). Therefore, when being propagated along the wave guide path, the high frequency current leaked from the hole or gap of the chassis is absorbed by the ferrite ring, without being radiated to the outside.
