2 sealing rings are provided with slotting female joint soon, after pin end insertion, the first sealing ring 1b of public access cephalic par can be with
Gas in sealing pipeline does not leak, and the second rubber ring 1c of pin end root can ensure that not permeable drain to of ambient outside air is led
Electric material, to cause the permanent magnet 2a between 2 sealing rings to be isolated with outside, avoid external substance (such as the greasy dirt of automobile,
Moisture in air etc.) conductive structure 2a and the metal clips stretched into main line are caused to corrode, so as to extend its life-span.It hurry up
Insert female joint and slotting pin end also include a lock ring structure (jump ring 1e and snap ring 2b) soon, ensure that pin end can be by after inserting
Specific position is stuck in, except non-operator presses retaining connector 3a, can just extract pin end, effectively ensures slotting public access soon
Steadiness after head insertion.In addition, the second sealing ring 1c is limited in locating ring 1d and slotting female joint private side soon by locating ring 1d
In groove between wall, avoid skidding off when plugging pin end.In the case of the technical scheme realizes gas circuit conducting, circuit is led
It is logical；When quick connector 2 is deviate from, the Hall sensor 1g of main line female joint can not normal induction inserted to fast on pin end forever
Magnet, so as to send a signal to electronic control system (ECU).
Compared with prior art, the present embodiment has advantages below：
1. installation is simple, it is only necessary to which quick connector is inserted in the i.e. achievable gas circuit in both ends and the conducting of circuit of main line；
2. pass through the Hall sensor on the permanent magnet and main line that are set on quick connector, it is possible to achieve both do not connect
Monitor whether quick connector is deviate from the premise of touching；
3. being isolated the permanent magnet in pipeline with outside by 2 sealing rings, permanent magnet is not polluted by environment, prolong
The service life of pipeline is grown；
4. having shackle designs, quick connector can be firmly fixed in main line.
Preferred embodiment of the present utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as using the common side in this area
