Problems solved by technology

[0004] (2) The shielding effect of the sensor body and the outgoing cable. The sensor is usually susceptible to electromagnetic interference, and the outgoing line must provide a 360° full-band low-impedance lap as much as possible;
[0005] (3) Protection against bending of the outgoing cable. The main body of the sensor is usually made of stainless steel, and the cable is usually soft. The cable at the exit position is easily damaged due to bending, which affects product performance.
[0007] (1) Most of them are fastened with a cable taper, which will cause damage to the cable;
[0008] (2) In order to protect and tighten the outgoing cables, the tightening head is installed and fixed with the top cover through threads, and the reliability is low under special conditions such as strong vibration

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the outlet device of the sensor cable of this embodiment includes a top cover 1, a tight head 2 and an elastic ferrule 3, and one end of the top cover 1 is used to fasten the sensor housing 10; the top cover 1, the tight head 2 Both the elastic ferrule 3 and the elastic ferrule 3 are provided with wire holes for the cable 9 to pass through. The elastic ferrule 3 is installed between the top cover 1 and the tightening head 2, and the other end of the top cover 1 and the tightening head 2 are fastened together. The connection is used to squeeze the elastic ferrule 3 to expand laterally so that the elastic ferrule 3 squeezes the cable 9 to fasten the cable 9 . Among them, the elastic ferrule 3 is a nitrile rubber ferrule or a fluorosilicone rubber ferrule; due to the good shrinkage of the nitrile rubber ferrule o...

Abstract

The invention discloses a sensor cable outgoing device, which comprises a top cover, a packing head and an elastic ferrule, wherein one end of the top cover is used for being tightened with the shellof the sensor; the top cover, the packing head and the elastic ferrule are all provided with holes for enabling the cable to be arranged in a passing mode; the elastic ferrule is arranged between thetop cover and the packing head; and the other end of the top cover and the packing head are in matched and tightened connection for squeezing the elastic ferrule to expand horizontally to squeeze thecable to tighten the cable. The sensor cable outgoing device has the advantages of pulling resistance, bending resistance, high reliability and the like.

Description

technical field [0001] The invention mainly relates to the technical field of power cables, in particular to a cable outlet device for a sensor cable. Background technique [0002] At present, for the convenience of installation, some pressure sensors usually adopt the installation method of cable swinging. This installation method needs to solve several problems: [0003] (1) The degree of tightness between the main body of the sensor and the outgoing cable is generally measured by the tensile force of the cable, which is usually required to be greater than 100N, and may also meet the requirements of certain high-strength vibration environments for the sensor; [0004] (2) The shielding effect of the sensor body and the outgoing cable. The sensor is usually susceptible to electromagnetic interference, and the outgoing line must provide a 360° full-band low-impedance lap as much as possible; [0005] (3) Protection against bending of the outgoing cable. The main body of the...
