Problems solved by technology

Due to the high impedance, there is no suitable path for the charge to drain away, which may result in corruption of acquired vibration data
[0004] The two ends of the L5 connector are respectively connected to the cable, and one end of each cable is connected to the other cable through the L5 connector. In actual use, the low-noise cable usually breaks at the j

Abstract

The invention discloses an L5 connector structure for a low-noise cable. The cable comprises a cable core wire, a cable shielding layer and a cable sheath, wherein an L5 connector comprises a connector plug, a connector pin and a connector sleeve; an inner hole of the connector plug and the cable sheath are in threaded connection; the connector sleeve is crimped at the outer side of the cable sheath in a polygonal form; and the outer wall of the connector sleeve and the outer wall of the cable sheath are in reinforced connection through a double-wall tube. By a mode of combining three threaded connection, crimping and gluing methods, the boning force of the connector and the cable is increased; the combined part of the connector and the cable is reinforced; and the cable is not easy to break at work. The invention further discloses a connection method of the low-noise cable and the L5 connector.

Description

technical field [0001] The invention relates to the field of low-noise cables used with charge output piezoelectric accelerometers, in particular to a low-noise cable L5 connector structure and connection method. Background technique [0002] Low noise cables are specially designed for use with charge output piezoelectric accelerometers. It can also be used with low-impedance IEPE accelerometers. The most essential difference between low-noise cables and standard cables is the insulating layer of low-noise cables plus a special conductive layer. The conductive layer greatly reduces static electricity generated by friction between the shield and the center conductor due to cable movement. [0003] This phenomenon is called "triboelectric effect". When the cable is not connected to any equipment or when the cable is connected to a high impedance device, a large amount of static charge can be generated. When using a charge output piezoelectric accelerometer, the impedance of...
