Problems solved by technology

[0005] During the production process of the existing conductivity probe, such as figure 1 and figure 2 As shown, the positioning tube 5 is used to pass through the middle of the magnetic ring 1, and after the magnetic ring 1 is fixed, the magnetic ring 1 is wrapped with hot-melt resin 3 to make a probe, but there are a series of problems in the probe made by this method, for example, due to It is impossible to ensure that the thickness of the solidified hot-melt resin 3 on the outer layer of the magnetic ring 1 is uniform, resulting in the inconsistency of the pressure resistance performance of the probe in all directions, resulting in poor pressure resistance of the probe; because the positioning tube 5 needs to be fixed and positioned when the magnetic ring 1 is packaged, resulting in After the packaging is completed, there will be a gap between the joint of the positioning tube and the probe shell 6. Due to technological problems, it cannot be guaranteed that the gap will be completely sealed. Therefore, there is a certain probability that the probe will leak, which will cause the temperature, salt and depth measuring instrument damaged by water

Abstract

The invention discloses a manufacturing mold and method for a conductivity probe of a conductivity-temperature-depth measuring instrument. The manufacturing mold comprises an upper mold plate and a lower mold plate. The upper mold plate and the lower mold plate are each provided with a primary packaging positioning cavity and a secondary packaging positioning cavity for accommodating a magnetic ring and a base, wherein a runner is formed between the primary packaging positioning cavity and the secondary packaging positioning cavity, and the primary packaging positioning cavity and the secondary packaging positioning cavity each comprise a vertical positioning groove for accommodating the magnetic ring and a horizontal positioning groove for accommodating the base. Sliding blocks are arranged on the lower mold plate and located on the two sides of the vertical positioning grooves, primary packaging positioning columns and secondary packaging positioning columns are oppositely arranged on the sliding blocks in the direction facing the vertical positioning grooves, the primary packaging positioning columns are located on the two sides of the vertical positioning groove of the primary packaging positioning cavity, and the secondary packaging positioning columns are located on the two sides of the vertical positioning groove of the secondary packaging positioning cavity. The conductivity probe manufactured through the manufacturing mold and method is simpler in structure, complete sealing can be achieved, and the hidden danger of water leakage of the conductivity probe is thoroughly avoided.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a manufacturing mold and a manufacturing method of a conductivity probe of a temperature, salt and depth measuring instrument. Background technique [0002] Conductivity, Temperature, Depth (Conductivity, Temperature, Depth) measuring instrument is used to measure three basic physical parameters of water body temperature, depth and conductivity. According to these three parameters, various other physical parameters can also be calculated, such as the speed of sound, etc., which is a necessary equipment for the investigation of oceans and other water bodies. [0003] The temperature, salinity and depth measuring instrument includes three sensors, which are temperature sensor, pressure sensor and conductivity sensor, and the conductivity probe is the sensor used to measure the conductivity of water body. [0004] Conductivity sensors are divided into electrode type and electromagn...
