A wire high pressure sealing structure

Abstract

The invention discloses a wire high-voltage sealing structure, which belongs to the technical field of aluminum silver oxide batteries, and comprises a first non-metallic frame, a second non-metal frame, a base body, a non-metallic cover plate, an upper metal pressure plate and a lower metal plate with the same structure Pressing plate; the first non-metallic piece includes a lower cylindrical body and an upper cylindrical body; the second non-metallic piece has the same structure as the first non-metallic piece; a lock nut is connected to the outside of the base body; the upper metal pressing plate is a ring structure; The first non-metallic component, the second non-metallic component, the base body, the non-metallic cover plate, the upper metal pressure plate and the lower metal pressure plate are in a coaxial relationship; a second O-ring is arranged between the second non-metallic component and the base body ; The second non-metallic piece and the wire are directly provided with the first O-shaped sealing ring; the upper cylindrical body, the upper non-metallic cover plate and the upper metal pressure plate are fixedly connected. The invention improves the reliability of wire sealing under high pressure.

Description

technical field [0001] The invention belongs to the technical field of aluminum silver oxide batteries, and in particular relates to a wire high-voltage sealing structure. Background technique [0002] Since the aluminum silver oxide battery has the characteristics of high specific energy and high specific power, and during the storage of the battery, the electrolyte is solid and non-conductive. When in use, seawater is inhaled to form an electrolyte to activate the battery, and it is widely used in equipment reserve batteries. [0003] During the working period of the aluminum silver oxide battery, tap wires need to be drawn from the stack chamber filled with high-temperature, high-pressure, and high-concentration lye to supply power to the equipment. The lead-out structure must meet the requirements of insulation, alkali corrosion resistance, and high-pressure sealing. At present, the wire lead-out structure is in the form of potting sealant on the joints. Since the sealan...

Problems solved by technology

At present, the lead-out structure of the wire is the way that the joint is potted with sealant. Because the sealant is incompatible with the wire insulation jacket, there is a gap between the wire and the sealant, resulting in the leakage of high-pressure lye in the gap, resulting in seal failure.
