Problems solved by technology
[0003] Due to the problem of the accuracy of the magnetic core, the current glue filling process requires constant repair and grinding of the inner opening size of the flange for each assembly. At the same time, in order to prevent the glue from flowing out from the end face of the magnetic core and the flange, glue needs to be applied. Filling the gaps and cleaning up the excess colloid after the colloid is cured, these application restrictions bring a lot of assembly work to the production

The invention discloses an opening and closing type sensor sealing structure and method. The problem that the precision of the sensor is poor due to the fact that the rubber curing shrinkage stress isdifferent due to segmented sealing of the sensor in the prior art is solved, the method has the beneficial effects that the workload is simplified, and the consistency of the shrinkage of the colloidcan be ensured. According to the scheme of an opening and closing type sensor sealing structure, the sensor comprises bottom shells which are arranged in a sectional mode, a plurality of sections ofbottom shells can be spliced into a ring shape, a section of magnetic core is arranged on the inner side of each section of the bottom shell, the sealing structure comprises a connecting piece arranged between two adjacent magnetic cores, an end face sealing gasket arranged between every two adjacent bottom shells, an elastic part arranged between the magnetic core and the inner side of the bottomshell, and a detachable annular glue filling tool arranged on the inner side of the magnetic core.
Description
technical field [0001] The invention relates to the field of sensor gluing and sealing, in particular to an open-close sensor sealing structure and method. Background technique [0002] At present, the inside of the open-close sensor mainly adopts a toroidal magnetic core, and the magnetic core is evenly cut into two parts. When the two parts are separately sealed and protected, the curing shrinkage stress generated during the curing process of the colloid is different, so that the magnetic core of the sensor cannot be tightly flattened after assembly. Alignment, the data collected by the sensor will be quite different, and the upper platform software will not be able to analyze the quality and authenticity of the data. In order to ensure the data consistency of the sensor and improve the production efficiency, it is very necessary when the sensor adopts the integrated sealing method. [0003] Due to the problem of the accuracy of the magnetic core, the currently used glue ...
