Abstract
It the utility model is related to a kind of water level sensor, including bundle assembly, inductor assembly, housing, inductor assembly is integrated with housing injection, and the wiring board being fixed in housing, bundle assembly includes two conducting wires, conducting wire one end rat tail assembly, the other end weld in the circuit board, it is characterised in that：The wiring board is scheduled in housing by turning over rivet clasp；Silica gel is filled in the housing；Heat-shrink tube is surrounded by outside the conducting wire；The bundle assembly is additionally provided with the rubber sleeve for fixing heat-shrink tube；The internal diameter of the rubber sleeve towards one end of housing is less than the outside diameter of heat-shrink tube；The utility model provides a kind of conducting wire and is not easy to wreck, installs more flexible water level sensor.
Description
Technical field
It the utility model is related to liquid level class field of sensing technologies, and in particular to one kind is used to detect deputy tank anti-icing fluid liquid level
Water level sensor.
Background technology
At present, domestic liquid level class sensor is divided into：Dry-reed, oscillating rod type, electrode type liquid level sensor；Deputy tank category
In engine system, because state's intrinsic motivation manufacture level and international engine level have gap, user not to make by product description
With etc., cause in deputy tank that anti-icing fluid impurity is especially more, environment is quite severe, and dry-reed liquid level sensor uses ring due to it
Border limits, and cannot be used for detection deputy tank liquid level substantially, and oscillating rod type liquid level sensor is influenced because of its volume, it is impossible to installed in secondary water
In case, traditional integrated electrode type liquid level sensor includes bundle assembly and inductor assembly, the conducting wire welding of bundle assembly
On the wiring board of inductor assembly, wiring board is fixed in the housing of inductor assembly, then silica gel is filled in housing, silica gel
A conducting wire part can be solidified after solidification, and conducting wire solidification part and the junction of movable part during installation or are deposited
Easily stress concentration is produced during taking and causes fractureing for conducting wire.
Utility model content
The purpose of this utility model is to provide a kind of convenient installation, the water level sensor of service life length.
Technical solutions of the utility model are as follows：A kind of water level sensor, including bundle assembly, inductor assembly, housing, sense
Answer device assembly to be molded with housing to be integrated, and the wiring board being fixed in housing, bundle assembly include two conducting wires, conducting wire one
Rat tail assembly is held, the other end welds in the circuit board, it is characterised in that：The wiring board is scheduled on housing by turning over rivet clasp
It is interior；Silica gel is filled in the housing；Heat-shrink tube is surrounded by outside the conducting wire；The bundle assembly is additionally provided with for fixed heat
The rubber sleeve of the draw；The internal diameter of the rubber sleeve towards one end of housing is less than the outside diameter of heat-shrink tube.
The utility model is further arranged to, and the rubber sleeve is connected in bundle assembly.
The utility model has the advantages that：Wiring board is fixed in housing by turning over riveting, connection deformation is small, even
Contact is solid and reliable, and riveting quality is stablized, and repeatability is high, and the dynamic fatigue strength of riveting point is high, far superior to the tradition such as spot welding
Thin plate Joining Technology, while it also avoid the problems such as desoldering occurs in traditional welding；It is surrounded by hot place pipe outside conducting wire, hot place pipe can be with
Give conducting wire improve a small activity space, solidification part and the junction of movable part conducting wire can easily rotate,
Damage more flexible and not easy to break is installed.
Brief description of the drawings
Fig. 1 is the structure diagram of water level sensor in the present embodiment.
Fig. 2 is the structure diagram of square bundle assembly and housing coupling part point in the present embodiment.
Figure label implication is as follows：1- bundle assemblies；11- conducting wires；2- inductor assemblies；3- housings；4- wiring boards；5- heat
Su Guan；6- rubber sleeves.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
With reference to Fig. 1 to Fig. 2, the utility model provides a kind of water level sensor, including bundle assembly 1, inductor assembly
2, housing 3, inductor assembly 2 is integrated with the injection of housing 3, and the wiring board 4 being fixed in housing 3, bundle assembly 1 include
Two conducting wires 11,11 one end rat tail assembly 1 of conducting wire, the other end are welded in assist side 4, it is characterised in that：The line
Road plate 1 is scheduled in housing 3 by turning over rivet clasp；Silica gel is filled in the housing 3；The outside of conducting wire 11 is surrounded by heat-shrink tube 5；Institute
The bundle assembly 1 stated is additionally provided with the rubber sleeve 6 for fixing heat-shrink tube 5；The internal diameter of the one end of the rubber sleeve 6 towards housing 2
Less than the outside diameter of heat-shrink tube 5；The rubber sleeve 6 is connected in bundle assembly 1.
Due to the setting of heat-shrink tube 5, conducting wire 11 and traditional difference in solidification with movable junction, there is movable sky
Between, convenient to rotate, installation is more flexible.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification, above-mentioned vacation can also be made
If these improvements and modifications also should be regarded as the scope of protection of the utility model.
