Automobile pipeline detection quick plug connector

Abstract

The invention discloses an automobile pipeline detection quick plug connector which comprises a shell, two inner sealing rings, an isolating ring, a safety ring, a lock spring, an electric plug, a circuit board, a switch, a first cover plate, two inserting needles and an electric wire. The shell is provided with a connecting pipe end, a first cavity, a second cavity and a plug-in cavity; the two inner sealing rings are sequentially embedded in the first cavity; the isolating ring is clamped between the two inner sealing rings; the safety ring is embedded in the first cavity; the lock spring isembedded in the first cavity; one end of the electric plug is in clamped connection with a limiting groove of the electric plug; the circuit board is clamped in a limiting groove of the circuit board; the switch is installed on a switch base; the first cover plate is inserted into the top of the plug-in cavity; needle heads of the two inserting needles penetrate through two needle inserting holesto be welded to needle inserting welding holes of the circuit board; and one end of the electric wire is welded to an upper hole of an electric wire welding hole of the circuit board, and the other end of the electric wire is connected with a lower hole of the electric wire welding hole. The automobile pipeline detection quick plug connector has the beneficial effects that the function of recognizable diagnosis is realized, production and assembly are easy, and mass production can be realized.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a quick-plug connector for automobile pipeline detection. Background technique [0002] The intelligence of the vehicle is based on various sensors and auto parts with diagnostic functions to realize that each module or component of the vehicle provides various signals in real time, and then the original signal is converted and output to the user after being processed by the ECU. In addition, with the improvement of emission regulations, real-time detection, monitoring, and alarm requirements for possible emission locations have gradually become necessary functions for all vehicles. For example, the National VI emission standard stipulates that the OBD system (On-BoardDiagnostics, on-board automatic diagnosis system) of the National VI standard car can perform "crankcase ventilation (PCV) system detection". If the gas manifold is disconnected, the OBD system shou...

Problems solved by technology

[0003] The crankcase ventilation system of the current car cannot know whether it is disconnected in time. Once the crankcase ventilation system is disconnected, exhaust gas will leak, which will not only pollute the environment, but also reduce the power and economy of the engine.

On the other hand, there is no detection function in the existing push-in connectors, and the detection function in the pipeline is realized based on expensive sensors, which has various problems for pipeline layout and product economy.
