Problems solved by technology

However, the traditional electric field sensor packaging cover is a single flat plate structure. As the sensor volume decreases, the effective sensing structure area decreases, the electric field sensing efficiency becomes lower and lower, and the sensitivity and resolution of the sensor also decrease.
In addition, although the traditional packaged shell structure achieves effective protection for the electric field sensor, it also causes further attenuation of the sensor sensitivity and other indicators, resulting in a blank for the sensor in the field of weak voltage / electric field detection

Embodiment 10

[0073] According to the above-mentioned packaging method and the packaging structure in which the inner core on the packaging cover plate is simultaneously convex and convex described in the specific embodiment 3, the present invention correspondingly proposes a specific embodiment 10 of the packaging method, and the steps specifically include:

[0074] Step 1: Prepare the packaging cover plate;

[0075] First, the processing of the edge 4(a) of the cover plate: process the edge 4(a) of the sheet-shaped cover plate by die stamping. Metal materials suitable for stamping include low carbon steel, stainless steel, aluminum and aluminum alloys, copper and copper alloy, etc., preferably iron-cobalt-nickel alloy. Electroplating treatment is carried out after stamping to prevent rust and oxidation. The coating is generally zinc, nickel, gold and other metals or their alloys, preferably gold coating. Holes of preset shapes such as circles and squares are reserved inside the edge 4 (a...

Abstract

The invention discloses a packaging cover plate of a sensitivity-strengthened electric field sensor and a packaging method and relates to the technical field of electric field detection. The packaging cover plate comprises an inner core, a cover plate edge and an isolation ring, wherein the inner core is located in the middle of the cover plate and above the sensitive face of the packaged electric field sensor, and the sensitivity of the electric field sensor is effectively strengthened. The cover plate edge is used for connecting a packaging pipe housing. The isolation ring is located between the cover plate edge and the inner core to play supporting and isolation effects. In addition, the packaging convenience is further increased by adopting the structure. Correspondingly, the structure is successively prepared by adopting the packaging method of the corresponding electric field sensor.

Description

technical field [0001] The invention relates to the technical field of electric field monitoring, in particular to a packaging cover plate and a packaging method of a sensitivity-enhanced electric field sensor. Background technique [0002] Electric field monitoring is of great significance. In the field of meteorology, monitoring the surface and high-altitude atmospheric electric field changes can provide information on the breeding, development and occurrence of lightning, and provide important indicators for lightning early warning, thereby providing important safety guarantees for the launch of missiles and satellites and other aircraft. Forests, scenic spots, transmission lines, and petrochemical refineries provide early warning information; in the field of power grids, monitoring the electric fields near transmission lines and substations can accurately obtain AC and DC voltage and phase information, providing important reference for smart grid transmission status, and...
