Description
Technical Field
[0001] The utility model belongs to the technical field of inertial navigation sensors and relates to a waterproof shell of an inertial navigation sensor. Background Art
[0002] The housing of the inertial navigation sensor is usually made of high-strength, lightweight materials such as aluminum alloy, titanium alloy or composite materials. These materials have excellent mechanical properties and corrosion resistance, and can effectively resist external shock, vibration and harsh environment. At the same time, the housing also uses precision processing technology to ensure that the connection between the sensor and the housing is tight and stable to avoid loosening or damage. The accuracy and stability of the inertial navigation sensor, as the core component of the navigation and positioning system, are crucial. As a protective layer for the inertial navigation sensor, the housing must be able to effectively prevent external moisture from invading, otherwise a series of serious problems will occur.
[0003] Water intrusion may cause short circuit or damage to the internal circuit of the inertial navigation sensor. Water is conductive. Once it enters the sensor, it may come into contact with the circuit components, forming a current path, which in turn causes a short circuit. Short circuit not only affects the normal operation of the sensor, but may also cause permanent damage, resulting in the failure of the entire navigation system. Therefore, there is an urgent need for an inertial navigation sensor waterproof housing to solve the above problems. Utility Model Content
