Silicon nitride electrode protecting cover

Abstract

The invention discloses a silicon nitride electrode protecting cover. The silicon nitride electrode protecting cover comprises a baffle block, lugs, a protecting cover shell, internal threads, cavities, compression springs and clamp blocks, wherein the protecting cover shell is of a cylindrical bucket body structure, the lugs are annularly mounted in the middle of the outer side of the protecting cover shell, the internal threads are mounted on the upper and lower ends of the protecting cover shell, the cavities are formed in the upper and lower ends of the protecting cover shell, the baffle block is mounted in the middle of the protecting cover shell, clamp blocks are mounted on the upper and lower sides of the middle of the protecting cover shell and are fixedly connected with the compression springs, and the compression springs are fixedly connected to the inner wall of the protecting cover shell. The silicon nitride electrode protecting cover has the advantages of high and uniform compactness and excellent thermal shock resistance, and the silicon nitride electrode protecting cover can resist corrosion and high temperature, is not influenced by reducing atmospheres, is long in service life and is particularly applicable to electrode protection under severe conditions such as hydrogen reduction furnaces.

Description

technical field [0001] The invention relates to the technical field of electrode auxiliary devices, in particular to a silicon nitride electrode protective cover. Background technique [0002] At present, in the field of automobile manufacturing, lead-acid batteries are widely used to provide electric energy for automobile ignition and on-board electrical appliances. The existing battery electrodes are usually directly exposed outside the casing. Due to the limited installation space on the automobile, it is necessary to disassemble and install the battery accessories. When removing parts, metal wrenches, etc. can easily touch the electrodes, which will cause wear of the electrodes, discharge and short circuit of the battery, and even cause electric shock to the human body. Contents of the invention [0003] The purpose of the present invention is to provide a silicon nitride electrode protection cover to solve the problems raised in the above-mentioned background technolo...
