Description
Technical field
The present invention relates to a kind of fuel level sensors, particularly a kind of oil box level sensor for vehicle.
Background technology
Oil box level sensor is mainly used for prompting the surplus of fuel oil in driver's fuel tank, in order to which driver fits
When fuel up, prevent the vehicle midway stagnation of movement caused by empty.The fuel level sensor used at present, due to being subject to pasta ripple
Dynamic influence, as float fluctuates in mailbox with oil mass, contact is frequently slided, and circuit board is susceptible to the event such as short circuit
Barrier.Particularly during replacement, since component is all sealing, it is less useful for dismantling.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of circuit board element, switch touching control is not immersed directly in
In oil, effectively evade the oil box level sensor for vehicle of pasta influence of fluctuations and replacement easy to disassemble.
In order to solve the above technical problems, the present invention realizes as follows：A kind of fuel level sensor, hollow housing
It is interior including junction block, connection iron plate, sealing rubber pad, clamp nut, hollow stainless steel tube, magnetic float, seal plug, annular
Protrusion and sensing circuit plate；The both sides of lower part are respectively equipped with the first symmetrical card slot in the housing, in the housing
Bottom set there are three fuel feed hole, the first square card hole is respectively equipped on the journal stirrup of the housing oral area both sides, in the shell
Portal equipped with a housing conducting wire in the front of body oral area；Both sides in cap are respectively equipped with the second symmetrical card slot, described
The back side of cap is portalled equipped with a cap conducting wire, is respectively equipped with the first wedge shaped projection in the both sides of the cap, the two first
Wedge shaped projection engages respectively with the first square card hole on the housing oral area both sides journal stirrup；Middle part on back side of shell top
Position is equipped with the second wedge shaped projection, and stick, the housing conducting wire are oriented to being respectively equipped with installation in the middle part of back side of shell both sides
Portal to portal with the box cover conducting wire and align；The stainless steel tube upper end be equipped with the annular protrusion, the junction block with it is described
The junction of stainless steel tube upper end is equipped with annular slot, and the stainless steel tube is fastened and connected with the junction block；The stainless steel
Pipe is connected by the clamp nut and the connection iron plate, and the sealing rubber pad is equipped with below the connection iron plate；It is described
Hollow magnetic float is sleeved on the stainless steel tube, and the stainless steel tube lower end is sealed with the seal plug.
The positive effect of the present invention：Since circuit board does not have to be immersed directly in oil, therefore extend the use longevity of each component
Life；Effectively evade pasta and rock the influence detected to sensor；The application of positioner is more advantageous to dismantling, cleans, ties up
It repaiies.
