Description

Technical Field

[0001] The invention relates to a hemispherical resonant gyroscope detection device, and in particular to a tool and method for quickly checking the insulation performance of a gyroscope end cover assembly. Background Art

[0002] The hemispherical resonant gyroscope is a new type of solid gyroscope with high precision, high reliability and long life. Its working principle is to use the radial standing wave precession effect of the hemispherical shell lip to sense the rotation of the base. Since the hemispherical resonant gyroscope has no moving parts, it has the advantages of low internal power consumption, insensitivity to magnetic fields, and few potential failure factors. It has high measurement accuracy, super stability and reliability, good shock and vibration resistance, high dynamics and low noise.

[0003] The basic structure of a hemispherical resonant gyroscope includes a sensitive component located inside the gyroscope. The excitation electrode and detection electrode of the sensitive component need to be led out to the outside of the gyroscope through the end cap assembly; see Figure 1 The end cap assembly includes an end cap base 01 and twenty-four insulators distributed thereon. The insulators are divided into short pin insulators 02 and long pin insulators 03, and each insulator corresponds to an independent electrode point. The end cap base 01 is divided into a concentric short pin insulator distribution circle Φa and a long pin insulator distribution circle Φb located therein. The short pin insulators 02 and the long pin insulators 03 are evenly distributed on the short pin insulator distribution circle Φa and the long pin insulator distribution circle Φb respectively. The end cap base 01 and the insulators are both made of metal, and the two are connected by a glass sintering part 04. According to the needs, each insulator should meet a certain insulation strength with the end cap base 01, so it is necessary to perform insulation resistance test and dielectric strength test on them.

[0004] Insulation resistance test is generally measured directly with insulation resistance tester or megohmmeter; dielectric strength test is generally carried out with dielectric strength tester, which applies AC power of a certain power capacity to the test end and keeps the power on for a certain time, generally not less than 1 minute, and there should be no insulation breakdown during the process. After the dielectric strength test, the insulation resistance test needs to be carried out again.

[0005] Since the 24 insulators in the end cap assembly are independent of each other, during the test, insulation resistance test and dielectric strength test must be performed one by one between each insulator and the end cap substrate, which takes a long time and has low detection efficiency.

[0006] The Chinese patent (CN211293132U) discloses a bridge component for product insulation performance testing, which is provided with an insulator and a rigid connection metal part that can be detachably connected to multiple ports of the tested product at the same time. The metal part is provided with N detachable connecting pins, which can directly disassemble and assemble the bridge component and the product port without the need to use a screwdriver to fix it, thus reducing the installation and removal workload. However, when this solution is applied to the end cover assembly product, the pins of the bridge component need to be installed and connected to the product test ports one by one, and the pins and the product test ports need to have a high degree of matching. If the match is too tight, the product may be damaged during the disassembly process. If the match is loose, a large contact resistance will be generated, affecting the test results.
