Problems solved by technology

However, with the existing technology of connector connection structure, the joint part becomes the interruption link of shielding protection, and interference signals including electromagnetic interference are coupled and induced into the line, which seriously interferes with the detection of normal signals, making it deviate from the actual detection value, resulting in Real-time detection of failures and abnormalities; secondly, the corner structure of the transmission cable in the axle box is also a hidden danger of shielding leakage

Embodiment Construction

[0009] The shielding protection type integrated integrated sensor disclosed in the patent application of the present invention includes a sensing probe 1 and its fixing seat, a cable part 5 and a sealing connection flange, and the cable part 5 is composed of a signal transmission cable for sensing and transmitting signals and an external part of the cable. The cable sheath is formed, and the cable sheath is usually a rubber sheath. This embodiment is described by taking the installation of a high-speed train axle box as an example. The flange seat 6 of the sealing connection flange is sealed and fixedly installed on the axlebox box with built-in sensors, and the sealing sleeve 2 is detachably fixed on the chassis of the flange seat 6, and its detachable fixing structure includes screw connection and buckle fixing Connections, etc., 1 sealing sleeve 2 is threaded to connect the gland 4, the sealing sleeve 2 between the gland 4 and the flange seat 6 has a built-in sealing sleeve...

Abstract

The invention provides an integrated shield and protection sensor which comprises a sensing probe, a cable portion and a sealing connection flange. A flange base of the sealing connection flange is fixedly mounted on a box, the sensing probe is arranged in the box, a sealing sleeve is detachably fixed on a base plate of the flange base, the outer end of the sealing sleeve is connected with a pressing cover in a threaded manner, the sealing sleeve is embedded between the pressing cover and the flange base, the cable portion penetrates the box, the flange base, a sealing rubber sleeve and a cable hole of the pressing cover, and the sealing sleeve is extruded by screwing the pressing cover and can function in sealing. By the aid of the technical scheme, a signal transmission cable connector joint connecting structure is abandoned, and a transmission cable has continuous and complete shield and protection functions and can reliably work in working environments with strong vibration and strong interference.

Description

technical field [0001] The patent application of the present invention relates to the sensor transmission cable lead layout technology, in particular, it relates to the transmission cable lead layout technology of various detection quantity integrated sensors working in an environment full of electromagnetic interference signals. Background technique [0002] Take the shaft integrated sensor for high-speed trains as an example. The sensing probe is installed at the shaft end inside the shaft box, and the temperature sensing part and the speed sensing part are integrated inside. There are many harness leads in the transmission cable, and the signal in the shaft box The transmission cable is connected with the cable outside the axle box through the electrical connector on the axle box. Since the integrated sensor is in the high-speed running state of the high-speed train, continuous and strong vibration will affect the connection performance of the plug connector, resulting in...
