Description
Technical field
The utility model belongs to automobile technical field more particularly to a kind of vehicle liquid level sensor.
Background technique
Automobile is more and more common in people's lives, and engine coolant liquid level is detected by liquid level sensor in automobile
Height, the existing existing probe of probe-type liquid level sensor and PCB are using being welded to connect, complex process.Due to soaking for a long time
Enter in liquid, be architectural limitation, leakproofness also will receive influence, to influence the service life of sensor.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of vehicle liquid level sensor.
The purpose of this utility model is achieved through the following technical solutions:
Vehicle liquid level sensor including probe assembly, the PCBA connecting with the probe assembly, and is set to probe assembly
And the casing assembly outside PCBA, the probe assembly include probe, and plastic layer, the bottom end of the probe are coated on the probe
With PCBA plug connection.
Preferably, the casing assembly includes inner casing and external fixation kit, and the inner casing includes the upper casing snapped connection
Body and lower case, the lower case bottom form connection pedestal, are provided with the terminal connecting with the PCBA in the pedestal.
Preferably, setting is there are two mutually matched buckle in the upper housing and the lower case, and two buckles
Shape is not of uniform size.
Preferably, the shell column of the upper housing being set on bottom including a bottom and protrusion, the shell styletable
Face offers the through-hole interted for probe.
Preferably, the fixation kit is the nut cover being set to outside inner casing, and the nut cover is provide on described including one
The cover of shell bottom and the threaded post for being connected to the cover upper end offer screw thread in the threaded post.
Preferably, sealing ring is provided in the nut cover, the sealing ring is set on the inside of nut cover bottom end and screw thread
On the inside of column.
Preferably, the probe and the plastic layer are encapsulated injection molding.
The beneficial effects of the utility model are embodied in: the protection of secondary seal, enhancing are carried out by encapsulated and rubber ring
The leakproofness of sensor, extends the service life of sensor.Meanwhile it being played between connection cover using different size of buckle
Fool proof connection, so that installing faster convenience.
Detailed description of the invention
Fig. 1: the schematic perspective view of the utility model.
Fig. 2: another viewing angle constructions schematic diagram of the utility model removes nut structure at this time.
Fig. 3: the utility model Fig. 2 bottom views structural schematic diagram.
Specific embodiment
With reference to embodiments and attached drawing is specifically described the technical solution of the utility model, and the utility model discloses one kind
Vehicle liquid level sensor including probe assembly, the PCBA connecting with the probe assembly, and is set in conjunction with shown in Fig. 1-Fig. 3
Casing assembly outside probe assembly and PCBA.The probe assembly includes probe 1, is coated on the probe 1 by encapsulated injection molding
There is plastic layer.Encapsulated injection molding has done primary sealing well to probe.
Do not illustrate in the bottom end of the probe 1 and PCBA(figure) plug connection, the bottom end PCBA is connected with terminal.This is inserted
The mode of connecing avoids the cumbersome of welding procedure in the prior art.The casing assembly includes inner casing and external fixation kit, described
Inner casing 2 includes the upper housing snapped connection and lower case, and connection pedestal 3 is formed on the lower case bottom, the PCBA connection
Terminal 41 is arranged in the pedestal.Mutually matched buckle there are two settings on the upper housing and the lower case, in order to
It is easily installed, the shape or size of the first buckle 21 and the second buckle 22 can use different forms, play better fool proof
Effect.It snaps connection, i.e., upper housing uses buckle-shaped formula, and lower case uses convex form, mutually fasten and completes connection.When
So, button and protrusion can also mutual transpositions.Specifically, the upper housing includes that a bottom and protrusion are set on bottom
Shell column, shell styletable face offer for probe intert through-hole.The fixation kit is to be set to outside inner casing
Nut cover, the nut cover include a cover 5 for being provide with the upper casing bottom and the threaded post for being connected to 5 upper end of cover
51, screw thread is offered in the threaded post 51.The sealing ring for secondary seal, the sealing ring are provided in the nut cover
It is set on the inside of nut cover bottom end and on the inside of threaded post.In conjunction with encapsulated injection molding, the leakproofness of product is substantially increased, extends production
The service life of product.
Still there are many specific embodiments for certain the utility model, are just not listed one by one herein.It is all to use equivalent replacement
Or equivalent transformation and all technical solutions for being formed, within the scope of all falling within the requires of the utility model protection.
