Description

Non-detachable quick connector combination

Technical Field

The utility model relates to an automobile parts technical field, in particular to non-detachable quick connector combination.

Background

During operation of the engine, the high-pressure combustible mixture and burnt gas in the combustion chamber leak into the crankcase through a gap between the piston group and the cylinder to a greater or lesser extent, causing blow-by. The blow-by gas is composed of unburned fuel gas, water vapor, exhaust gas and the like, which can dilute the engine oil, reduce the service performance of the engine oil and accelerate the oxidation and deterioration of the engine oil. The water and the air are condensed in the engine oil to form oil sludge and block an oil way; acid gases in the exhaust gas mixed into the lubrication system can cause corrosion and accelerated wear of engine parts; blow-by also causes the crankcase pressure to be too high and the crankcase seal to be broken, allowing oil to leak and run off.

Crankcase ventilation must be implemented to prevent excessive crankcase pressure, extend engine oil life, reduce wear and corrosion of parts, and prevent engine oil leakage. In addition, crankcase ventilation system designs must also be implemented during automotive engine design to meet increasingly stringent emissions requirements and to improve economy. The new national emission standard provides that the blow-by gas of the crankcase cannot be discharged into the atmosphere so as to avoid air pollution, so that the gas separated by the oil-gas separation system must be led into an air inlet system of the engine and participate in combustion, and a crankcase ventilation pipe for communicating the crankcase and the air inlet system of the cylinder is required.

Chinese patent 201711020241.2 relates to an electrically conductive crankcase ventilation duct comprising: the quick-mounting connector is connected with the sealing pipe through an inserted male end and connected with an air inlet pipeline of the air cylinder through an inserted female end; a lead is arranged on the outer side of the sealing tube; the quick connectors at the two ends are both provided with a microswitch and a circuit board, the microswitch is positioned on the inner wall of the jack, the circuit board is connected with the microswitch and is arranged in the wiring groove, and the two ends of the two wires are both connected to the circuit board at the corresponding end to form a conduction loop; the circuit board at one end is also connected with an external electric plug for connecting with a main control ECU of the automobile so as to output on-off signals.

However, the quick-assembly quick-release joint which meets the national six standards in the form of signal feedback has the following problems in practical use:

1) the structure is complex, thus leading to high manufacturing and use costs, and the cost control requirements for specific customers are difficult to meet;

2) the structure is more complicated to lead to when using, the staff that needs to pass through special skill training assembles joint and ventilation pipe, and needs to spend relatively long man-hour and be unfavorable for the promotion of loading efficiency in the assembly stage of follow-up ventilation pipe intercommunication crankcase and cylinder air intake system.
