Embodiment Construction

[0017] The sealed lead-out assembly of the temperature sensor disclosed in this patent application is realized based on a sealed cable sheath.

[0018] Taking the application of oil-cooled motors as an example, the temperature-sensing front end of the temperature sensor sealing lead-out assembly is set in the cooling oil circuit of the motor winding, and its signal cable is led out of the cooling oil cavity to transmit the temperature-sensing transmission signal to the signal acquisition and processing system. In its actual installation, the sealing between the signal cable and the oil cavity is realized by the sealed cable sheath of the present application. The sealed cable sheath of this patent application is not only the outer insulation protection layer of the signal transmission inner core cable 3, but also a sealing entity that ensures that the signal cable does not affect the sealing of the oil chamber after the temperature sensor is installed.

[0019] The sealed cable...

Abstract

The invention provides a seal-type cable sheath, a manufacturing method thereof and a temperature sensor sealing lead-out assembly. The seal-type cable sheath comprises an insulating cable sheath anda sealing plug, wherein the insulating cable sheath penetrates through the center of the sealing plug. The sealing plug is made of a mixed material of polyamide and glass fiber, the insulating cable sheath is made of polyamide, and the sealing plug and the insulating cable sheath are integrated through thermoplastic die casting. The seal-type cable sheath is combined with a temperature sensor to form the temperature sensor sealing lead-out assembly. The technical scheme has the technical advantages of being simple in structure, good in sealing performance, low in manufacturing cost, wide in application range and long in service life.

Description

technical field [0001] This patent application relates to cable insulation and sealing protection, in particular to sensor signal transmission cables and their signal transmission cable setting position sealing lead-out structure. Background technique [0002] For many devices, especially sensor products, their signal cables need to pass between the closed space and the open space in their specific installation occasions, and the good sealing performance between the closed space and the open space should not be affected. [0003] Take the most widely used temperature sensor as an example. In order to implement accurate measurement, the temperature sensing front end should be as close as possible to the detected part. In practical applications, these detected parts are often in a closed environment, and are often filled with heat exchange media. Therefore, the installation technical requirements of temperature sensor products It is also required not to affect the sealing per...
