Problems solved by technology

But when it is >20Mpa, there will be obvious air leakage, and it cannot be used under high pressure conditions (>20MPa).
At the same time, the general high-voltage sealed electrical connector adopts glass sintering process to ensure high-pressure sealing, and the production process is more complicated and the cost is higher.

Abstract

The invention provides a sealed electric connector and a liquid level meter. The connector comprises a welding straight-through part, an upper wiring terminal, an outer sleeve nut and a lower wiring terminal. The welding straight joint is a hollow tubular column, one end of the welding straight joint is welded with the liquid level meter, the upper wiring terminal is arranged in a hollow inner cavity of the welding straight joint, and one end of the upper wiring terminal is welded with an output electric wire of the liquid level meter; the outer sleeve nut is a hollow tubular column with the two ends different in caliber, and the caliber of one end of the outer sleeve nut is larger than the diameter of the other end of the welding straight-through part. The lower wiring terminal is arranged in the hollow inner cavity of the outer sleeve nut, and one end of the lower wiring terminal is welded with a wire to be connected with external equipment; and the welding straight joint presses the other end of the upper wiring terminal to the other end of the lower wiring terminal in the outer sleeve nut by inserting the outer sleeve nut, so that the upper wiring terminal is conducted with the lower wiring terminal.

Description

technical field [0001] The invention relates to the application field of sensors, in particular to a sealed electrical connector and a liquid level gauge. Background technique [0002] The high-pressure sealed electrical connector used on the existing liquid level gauge has a theoretical air pressure of 8MPa. In actual use, with auxiliary means such as sealant, it can be used up to 20Mpa. However, when it is >20MPa, there will be obvious air leakage, and it cannot be used under high pressure conditions (>20MPa). At the same time, the general high-voltage sealed electrical connector adopts a glass sintering process to ensure high-voltage sealing, and the production process is relatively complicated and the cost is high. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a sealed electrical connector and a liquid level gauge, which can realize the reliable use of the liquid level gauge under high pressure and other environments throug...
