Abstract
The utility model discloses a waterproof structure of an engine oil pressure sensor, wherein a plastic cap is mounted at the top part of the housing, silicone sealant is mounted on both the housing and the outer part of the plastic cap, a screw is mounted at the top part of the plastic cap, and a waterproof ventilated membrane is mounted at the bottom part of the screw. Because the waterproof ventilated membrane structure is specially designed and added to the vent hole inside the engine oil pressure sensor, the reliability of the product is improved, therefore not only the waterproof function is effective, the excellent air permeability can be guaranteed, and the structure is simple. In addition, the installation adaptability of the engine oil pressure sensor can be improved, therefore the installation of the engine oil pressure sensor from any angles without influencing the permeability of the engine oil pressure sensor can be guaranteed.
Description
Technical field
The utility model relates to a kind of sensor water-proof structure, is a kind of engine oil pressure pickup waterproof construction specifically.
Background technology
At present, known engine oil pressure pickup can reflect the lubrication circumstances of engine, its major failure take the form of machine oil lamp Chang Liang, causing this cause faults is that the engine oil pressure pickup water inlet causes short circuit.Also do not prevent the waterproof construction of its short circuit now on the market.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, the engine oil pressure pickup waterproof construction that failure rate is low.
In order to achieve the above object, the technical solution adopted in the utility model is: in case top plastic cap is housed, housing and plastic cap outside are equipped with sealing silica gel, and screw is equipped with at the plastic cap top, in the screw bottom waterproof ventilated membrane are housed.
Since the utility model unique design increase the structure of waterproof ventilated membrane at engine oil pressure pickup inner vent hole place, reduced the failure rate of engine oil pressure pickup, improved reliability of products, not only effective waterproof, and it is can guarantee good gas penetration potential, and simple in structure.In addition, can also improve the installation adaptability of engine oil pressure pickup, guarantee the installation that realizes any angle of engine oil pressure pickup under the ventilative situation of engine oil pressure pickup not influencing.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is equipped with plastic cap 4 at housing 5 tops, and housing 5 and plastic cap 4 outsides are equipped with sealing silica gel 3, and screw 1 is equipped with at plastic cap 4 tops, in screw 1 bottom waterproof ventilated membrane 2 is housed.
A working chamber is arranged in oil-pressure shut-off switch, and this cavity is airtight fully, can not carry out circulation of air with the external world.Normal temperature influence down is less, subtle.Under product was in the condition of high temperature, inner air expanded, because of can not with extraneous conducting, the increase of inner chamber air pressure causes the oil-pressure shut-off switch operating pressure to increase significantly, can not correct response the true oil pressure of lubricating system at that time.In order to guarantee that the pressure equilibrium screw has ventilating structure, working chamber can not be intake again and dust etc. simultaneously, and this just requires to increase waterproof construction thereon, has adopted waterproof ventilated membrane to realize this function in the utility model.
