Description
Technical field
Sensor technical field is the utility model is related to, is more particularly related to a kind of for oxygen content detection in vehicle exhaust
Lambda sensor.
Background technology
At present, lambda sensor is sensing element crucial in BBG control system, for controlling vehicle exhaust
Discharge, pollution of the vehicle exhaust to environment is reduced, and improve automobile engine fuel oil burning quality, it is using zirconium oxide body in height
Under the conditions of temperature etc., if the oxygen concentration of zirconium oxide body both sides is different, potential difference, and concentration difference will be produced in zirconium oxide body both sides
Bigger, potential difference is bigger, and lambda sensor detects the concentration of oxygen in vehicle exhaust using this characteristic of zirconium oxide, and feeds back to
Engine control system, air-fuel ratio is maintained between certain ratio, but the probe junction of traditional lambda sensor is
There is no safeguard measure, it is easy to make dust and the direct trolley wire of water droplet, and corrode electric wire, so as to cause wire short-circuiting, enter
And the service life of lambda sensor is have impact on, during manually needing to change lambda sensor, manually directly contact electric wire meeting
It is easy to produce potential safety hazard, and is made troubles to artificial installing/dismounting.

State connecting seat and be arranged on probe rear end, the connection base rear end is provided with bellows, and the bellows is connected with the connecting seat
Connecing, the plug is provided with shell cutting ferrule, and the shell is socketed on the plug, and the shell connects in succession with card sleeve clamp, by
It is connected in bellows with the connecting seat, can avoids manually directly contacting electric wire, its advantage is the increase in security.
Preferably, the plug is additionally provided with through hole, and the plug is connected by through hole with the electric wire.
Preferably, plastic tube is provided with the outside of the electric wire, the plastic pipe sleeve is connected on the electric wire, the plastic tube
It is connected with the bellows, due to being provided with plastic tube on the outside of electric wire, and plastic tube is connected with the bellows, and
Protect electric wire not corroded by water droplet and dust, effectively raise service life.
Preferably, the plastic tube is additionally provided with Anti-slip cover, and the Anti-slip cover is socketed on the plastic tube, due to anti-skidding
It is socketed on the plastic tube, facilitates manually when dismounting is needed, lambda sensor of taking is convenient, and its advantage is installation
Convenient disassembly.
Preferably, the Anti-slip cover is demountable structure.
Compared with prior art, the utility model advantageous effects are mainly reflected in：The utility model passes through bellows and institute
State connecting seat to be connected, can avoid manually directly contacting electric wire, and plastic tube, while plastic tube are provided with the outside of electric wire
It is connected with the bellows, protects electric wire not corroded by water droplet and dust, and Anti-slip cover is socketed in the plastics
Guan Shang, facilitate manually when dismounting is needed, lambda sensor of taking is convenient, be able to can both be increased again with easy installation and removal
