Abstract

The invention discloses a special inward buckling gas-leak-proof hexagonal seat for oxygen sensors, which is characterized in that the hexagonal seat includes a front threaded area, a hexagonal seat area and a rear positioning area, the hexagonal seat area is located between the front threaded area and the rear positioning area, and the hexagonal seat area is connected with the front threaded areaand the rear positioning area as a whole. The hexagonal seat of the invention is of an integral structure, has high overall strength, can ensure good overall gas tightness of oxygen sensors and greatly improve the yield of oxygen sensors, and is suitable for popularization and application in the production and manufacture of automobile oxygen sensors.

Description

technical field [0001] The invention relates to the field of automobile oxygen sensor components, in particular to a special inner buckle anti-leakage hexagon seat for oxygen sensors. Background technique [0002] The oxygen sensor is an electrochemical chip that detects the oxygen ion composition in the gas to detect the concentration and dilute degree of oxygen in the gas, that is, the mixing ratio of oil and gas when the engine intakes, and then the oxygen sensor will detect the signal The output is fed to the central processing unit for analytical processing. The oxygen sensor is an important component of the fuel feedback control system of the automobile engine. The oxygen sensor consists of front and rear protective covers, hexagonal seats, positioning seats, chips, high-temperature seals and related signal transmission lines. Among them, the chip is installed on the positioning seat, the positioning seat and the chip are installed inside the hexagonal seat together,...
