Abstract

The invention discloses a miniature ceramic shell which comprises a ceramic base and a ceramic cap in airtight sealing fit with the ceramic base. The ceramic base and the ceramic cap are sealed to form a hollow structure, a first main electrode, a second main electrode, a first inner electrode area, a second inner electrode area, a base insulating cavity and a base sealing ring are arranged on theceramic base, and the ceramic cap is provided with a first auxiliary electrode, a second auxiliary electrode, a third inner electrode area, a cap insulation cavity and a cap sealing ring. According to the ceramic shell, the ceramic base and the ceramic cap form the hollow structure, and an upper-lower layer physical isolation structure is formed between the ceramic base and the ceramic cap, so that the insulation resistance and reliability of the shell are improved.

Description

technical field [0001] The invention relates to a casing, in particular to a miniature ceramic casing. Background technique [0002] Relay (Relay) is an electronic control device, which has a control system (also known as input circuit) and a controlled system (also known as output circuit), usually used in automatic control circuits, it actually uses a small current An "automatic switch" to control larger currents. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] Most of the existing relay housings are made of high-polyester plastic, and its main material is high-molecular organic materials, which are subject to certain restrictions on high temperature, high pressure, and high strength, and are prone to aging for a long time, which cannot meet the needs of existing high-tech products. , and there are a large number of harmful substances, low insulation resistance, low salt spray resistance, low load d...
