Example Embodiment

[0032] The technical solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0033] See figure 1 As shown, the sensor 10 includes a cable 10a, a probe 10b fixed at one end of the cable 10a, and an output terminal 10c fixed at the other end of the cable 10a, wherein the probe 10b needs to extend into the high-pressure and / or high-temperature environment cavity of the high-pressure container In this case, the output terminal 10c is located outside the aforementioned environmental chamber.

[0034] See Figure 2 to Figure 7 As shown, a cable sealing device in which the cable 10a on the sensor 10 extends in the up and down direction, the upper end is provided with an output terminal 10c, and the lower end is provided with a detection head 10b. The following is convenient for description, and the cable is explained based on the direction of the figure. The structure and installation connection relationship of each pa...

Abstract

The invention discloses a cable sealing device. The cable sealing device is simple in structure, a few parts are involved, installation and hermetic connection of a dumbbell-shaped sensor can be effectively achieved, so that a probe of the sensor can be arranged in a high-temperature and/or high-voltage environmental cavity for detection, an output terminal of the sensor can be arranged outside the environment cavity and is connected with other equipment to acquire a detection signal. The cable sealing device is convenient to install and is high in hermetic connection reliability.

Description

technical field [0001] The invention relates to a cable sealing device, in particular to a cable sealing device used in high temperature and high pressure environments. Background technique [0002] In order to collect relevant elements in a high-pressure environment, it is usually necessary to extend the probe of the sensor into the high-pressure environment cavity. At present, most of the sensors, one end of which is packaged by soldering, and the other end is connected to the output terminal in order to ensure the stability of the sensor. figure 1 Shown is a dumbbell-shaped structure, that is, a structure in which the middle cable portion of the sensor is smaller than the ends. At the same time, one end of the sensor is in the high-pressure chamber, and the other end passes through the high-pressure chamber and is located outside the high-pressure chamber. The middle cable part is just the part that needs to be sealed, and commonly used devices for high-pressure sealing ...
