Embodiment Construction

[0027] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0028] The safety protection structure design of the high pressure sensor is characterized in that:

[0029] A safety protection structure design of a high-pressure sensor is based on the existing technology, and a pressure sensor is designed for the requirements of 74-degree taper thread installation, miniaturization, sealing, and high pressure measurement. The structural design of this pressure sensor can meet the requirements of high pressure measurement, 74-degree taper thread installation, and complete machine sealing.

[0030] A high-voltage sensor safety protection structure includes a pressure-sensitive component 1 , a casing 2 and a socket 3 .

[0031] Such as figure 1 In the schematic diagram of the high-voltage sensor shown, the housing 2 is sequentially set on the printed circuit board component 7, the self-made...

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...
