Description

Ceramic high-voltage silicon stack with high-voltage-resistant upper cover

Technical Field

The utility model relates to the technical field of ceramic high-voltage silicon stacks, in particular to a high-voltage-resistant ceramic high-voltage silicon stack with an upper cover.

Background

In the case of the existing ceramic high-voltage silicon stack, the housing thereof is mainly composed of a ceramic housing and a metal upper cover. The upper cover is a metal parallel seal welding structure, in other words, the upper cover is a layer of metal cover. Referring to fig. 2, fig. 2 shows a housing structure of a ceramic high voltage silicon stack in the prior art. When the voltage exceeds a certain value, the internal chip is easy to affect the safe use of the product due to the phenomena of insulation, arc discharge, discharge breakdown and the like generated by the upper cover.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, namely when the voltage exceeds a certain value, the chip and the upper cover are easy to generate the phenomena of arc discharge, discharge breakdown and the like, the utility model provides a high-voltage-resistant ceramic high-voltage silicon stack of the upper cover, which comprises a ceramic shell and a metal cover, wherein the inner side of the metal cover is also provided with two layers of insulating covers.

The utility model is further provided with: the ceramic shell is provided with a concave platform for placing the two layers of insulating covers.

The utility model is further provided with: the two layers of insulating covers are made of ceramic materials.

The beneficial technical effects of the utility model are as follows:

1. through setting up two layers of insulating covers, kept apart chip and metal covering, greatly increased the holistic reliability of product and withstand voltage nature.

2. The concave table is designed to facilitate the positioning of the placement of the two layers of insulating covers and not to influence the installation of the metal cover.

Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1, the utility model provides a high-voltage resistant ceramic high-voltage silicon stack with an upper cover, which comprises a ceramic shell 1 and a metal cover 2. The inner side of the metal cover 2 is also provided with a two-layer insulating cover 3, and the two-layer insulating cover 3 is made of ceramic materials. The two layers of insulating covers 3 play a role in isolating the chip from the metal cover 2, and the overall reliability and pressure resistance of the product are greatly improved. The specific mounting structure is as follows: the ceramic shell 1 is provided with a concave platform 11 for placing the two-layer insulating cover 3, and the concave platform can be bonded and fixed or installed in an interference fit manner. The mounting structure has the advantages that: 1. the two-layer insulating cover 3 is convenient to place and position; 2. the installation of the metal cover 2 is not influenced; 3. the outer contour of the ceramic shell 1 is not changed, so that the ceramic shell can be continuously used by referring to the existing practical scene.
