Safety protection structure of high-voltage sensor

Abstract

The invention relates to a high-pressure pressure sensor for aviation, in particular to a safety protection structure of a high-pressure sensor. The structure comprises a pressure sensing part (1), a shell (2) and a socket (3) which are sequentially arranged, the weight reduction holes are designed in the damper to reduce the weight of the whole machine of the product, and the pressure guide holes of the damper are designed in the two sides and are perpendicular to the pressure inlet holes of the mounting sleeve, so that instantaneous high-pressure impact can be relieved, and a protection effect on the pressure core body is achieved; through the structural design of the pressing ring, protection on the pressure core body is increased from the two aspects of welding penetration depth and thread fixing, and the situation that unsoldering of the pressure core body increases the insecurity of a system under the extreme condition is prevented; and an inner hexagonal hole is formed in the damper, so that the damper is convenient to mount. The structural design of the pressure sensor can meet the requirements of high pressure measurement, 74-degree taper thread installation and complete machine sealing.

Description

technical field [0001] The invention relates to a high-pressure pressure sensor for aviation, in particular to a safety protection structure of the high-pressure sensor. Background technique [0002] With the gradual increase in system safety requirements and integration requirements, it is required to improve the safety design of high-voltage sensors without increasing the volume and weight of the product. The original high-pressure pressure sensor is large in size, and the small-sized high-pressure pressure sensor does not have enough safety design margin inside, resulting in the possibility of leakage or reduced product service life under the condition of instantaneous high-pressure shock. Therefore, under the premise of the existing volume and weight, the existing high-pressure pressure sensor technology is improved to improve the safety factor of the product when it is impacted by high pressure. Contents of the invention [0003] The present invention aims at the req...
