Coaxial connectors refer to the parts used to connect the ends of two shafts to ensure that the centerlines of the two shafts are on the same axis. It is generally used to connect the driving shaft and the driven shaft, and transmit the rotational motion of the driving shaft to the driven shaft. There is a relatively unpopular classification in coaxial connectors, triaxial connectors, the full name of Triaxial Connector, literally means that three cylinders are coaxial.

Definition of triaxial connector

A triaxial connector is a coaxial cable with two layers of outer conductors. layer composition. The inner core mainly transmits signals (such as videosignals) or supplies power to the machine head, and the inner skin and the inner core form a loop. The outer layer is the shielding layer and the ground layer. The outer diameters of the connecting cables are Ф8mm, Ф6.1mm and Ф4.5mm. The cables with thicker diameters can transmit longer distances because of their small transmission loss.

Compared with multi-core cables, triaxial cables have simple structure and high reliability; compared with two-core coaxial cables, they have higher shielding performance and small signal transmission capacity. The shielding performance of triaxial connectors is 40~50dB higher than that of unshielded connectors, and the shielding efficiency of triaxial cables is 9 times higher than that of single-layer copper braided cables.
