Description
Technical field
The present invention relates to a kind of sealing structures, particularly a kind of sealing structure of cooling-water temperature sensor.
Background technology
There are various sensors on vehicle, wherein there is cooling-water temperature sensor.Cooling-water temperature sensor is mounted on power by helicitic texture
In system, under normal circumstances, cooling-water temperature sensor can be mounted on thermostat base or on water out adapter, can also be mounted on other
Position is contacted directly with coolant, for testing the temperature of coolant.
Thermostat base and water out adapter originally, are made of metal materials such as cast iron, cast aluminiums, as vehicle is light-weighted
It is required that plastic material is used for manufacturing thermostat base and water out adapter, the plastic parts such as thermostat base and water out adapter made of plastics,
Have many advantages, such as that light weight, shaping are easy, at low cost.In order to effectively install cooling-water temperature sensor, it is desirable to provide with cooling-water temperature sensor
Matched helicitic texture since the intensity of plastic material is low, directly processes screw thread on plastic part, and the screw thread processed is strong
It spends low, it is impossible to fixed cooling-water temperature sensor.Therefore it is embedding that a metal is embedded on thermostat base made of plastics or water out adapter
Part, metal insert is equipped with helicitic texture, for fixing cooling-water temperature sensor.Cooling-water temperature sensor passes through Screw assembly with metal insert
Afterwards, coolant can be between metal insert and the faying face of thermostat base or water out adapter and cooling-water temperature sensor and metal insert
It leaks out, it is therefore desirable to which cooling-water temperature sensor is sealed.
The sealing structure of current engine water temperature sensor is as follows：As shown in Figure 1, it is embedding to be embedded with metal in plastic part 3
Part 2, then metal insert 2 and 1 Screw assembly of cooling-water temperature sensor, therefore between plastic part 3 and metal insert 2 and metal is embedding
O-ring 4,5 is respectively provided between part 2 and cooling-water temperature sensor 1, can effectively prevent coolant between metal insert and plastic part
And it is revealed between metal insert and cooling-water temperature sensor.However this sealing structure there are it is certain the defects of：I.e. entire sealing knot
Structure is complicated, causes that the assembly process is complicated, and production cost is high, and O-ring is easily damaged, and sealing effect is poor.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, the object of the present invention is to provide one kind is simple in structure, sealing effect is good
Cooling-water temperature sensor sealing structure.
To achieve these goals, the sealing structure of a kind of cooling-water temperature sensor designed by the present invention, including plastic part, gold
Belong to inserts and cooling-water temperature sensor, the metal insert are embedded on plastic part, between the cooling-water temperature sensor and metal insert
It is fitted together by screw thread, sealing element is assembled between the cooling-water temperature sensor and plastic part, the sealing element includes metal
Gasket and the rubber gasket being assembled on metal gasket, the rubber gasket are close with plastic part, cooling-water temperature sensor respectively
Sealing-in is touched.
Further, the rubber gasket is located in periphery and/or the inner circumferential of metal gasket.
Further, the rubber gasket is wholely set with metal gasket.
Further, the rubber gasket and metal gasket integrated vulcanizing are molded or integral bonding forming or are integrally assembled into
Type.
Further, the plastic part is thermostat base or water out adapter.
Further, the metal insert integrally or is pressed integral with plastic part injection.
Compared with prior art, the beneficial effects of the invention are as follows：Sealing element is assembled between cooling-water temperature sensor and plastic part,
And sealing element includes metal gasket and rubber gasket, metal gasket is used to support cooling-water temperature sensor, is passed in plastic part and water temperature
Gap is formed between sensor, rubber gasket can be prevented to be subject to crushing, rubber gasket connects with cooling-water temperature sensor, plastic part sealing
It touches, not only simplifies sealing structure, and ensure that sealing effect.
Description of the drawings
Fig. 1 is the sealed structural representation of cooling-water temperature sensor of the prior art.
Fig. 2 is the sealed structural representation of the present invention.
Fig. 3 is a kind of structure diagram of sealing element in the present invention.
Fig. 4 is another structure diagram of sealing element in the present invention.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in Fig. 2, a kind of sealing structure of cooling-water temperature sensor, senses including plastic part 8, metal insert 7 and water temperature
Device 6, the metal insert 7 are embedded on plastic part 8, can be molded between the metal insert 7 and plastic part 8 integrally,
It is integral that press fitting may be employed, fitted together between the cooling-water temperature sensor 6 and metal insert 7 by screw thread, the water temperature
Sealing element is assembled between sensor 6 and plastic part 8, the sealing element includes metal gasket 9 and is assembled on metal gasket 9
Rubber gasket 10, the rubber gasket 10 is in sealing contact with plastic part 8, cooling-water temperature sensor 6 respectively.
There are many kinds of the assembling modes of the rubber gasket 10 and metal gasket 9, for example rubber gasket 10 is located at gold
Belong on the periphery of gasket 9 either rubber gasket 10 to be located in the inner circumferential of metal gasket 9 or 10 part of rubber gasket
In on the periphery of metal gasket 9, partly be located at inner circumferential on or rubber gasket 10 be arranged on metal gasket 9, the present embodiment
In, rubber gasket 10 is located on the periphery of metal gasket 9, as shown in figure 3, rubber gasket 10 is assembled in metal gasket 9
One end, and rubber gasket 10 is on the outside, metal gasket 9 is in inside, as shown in figure 4, rubber gasket 10 is assembled in metal gasket
The both sides of piece 9, certainly, rubber gasket 10 and the set-up mode of metal gasket 9 are not limited to a kind of any of the above-described form, herein not
It enumerates again.
In the present embodiment, the rubber gasket 10 is wholely set with metal gasket 9, the specific can be integrated vulcanizing into
Type or integral bonding forming or integral molding assembly.
Wherein, the plastic part 8 can be the power of thermostat base or water out adapter, even other positions
System unit.
Wherein, the metals such as aluminium, copper, iron, steel may be employed in metal gasket 9, can also use alloy, rubber gasket 10 can
It, can also thermoplastic elastomer (TPE) to be the rubber such as ethylene propylene diene rubber, fluorubber, silicon rubber, nitrile rubber.
Cooling-water temperature sensor 6 is fixed on by helicitic texture on metal insert 7, and metal gasket 9 supports cooling-water temperature sensor 6,
Gap is formed between cooling-water temperature sensor 6 and plastic part 8.It can be from seam there are gap, coolant between metal insert 7 and plastic part 8
Gap leaks；It meanwhile also can be from gap leakage there is also gap, coolant between metal insert 7 and cooling-water temperature sensor 8.Rubber is close
In the gap that packing 10 is formed in metal gasket 9, one can prevent from being subject to crushing, secondly can have fixed compression；Rubber is close
Packing 10 contacts simultaneously with plastic part, cooling-water temperature sensor, forms sealing on contact surface, can block from gap at above-mentioned two
The coolant of leakage.
In the present embodiment, metal insert and plastic part integrated injection molding are omitted after heating metal insert carries out and are pressed
The step of, and need not O-ring be set on plastic part, and packaging technology is enormously simplified, reduces production cost, and it is effective
Solves the leakage problem of coolant.
