Description
Technical field
This utility model relates to liquid level sensor art, refers in particular to a kind of waterproof knot of liquid level sensor PCBA board
Structure.
Background technology
Liquid level sensor, is a kind of sensor of liquid level in measuring container, applies in vehicle-mounted, boats and ships, oiling
Stand, etc. place.Owing to it uses environment to be chronically exposed to outside, sensor wind and weather to be stood.Current level sensing
Device water resistance is the best, uses after a period of time, has liquid and enters into the electricity of sensor along aerial lug interface, electric wire
Inside sub-pipe, electronic original part is caused corrosion, so that sensor function lost efficacy, cause external connections normally to read
Actual liquid height；Further, liquid level sensor is arranged in casing, when variations in temperature in casing, liquid level can be caused to pass
The PCB of sensor seals the pressure change of cavity, and then aggravation rainwater is along the risk of electric wire seepage.Therefore, it is necessary to current
Liquid level sensor improves.
Utility model content
In view of this, this utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of liquid level and passes
Sensor PCBA board waterproof construction, it can effectively solve the problem that existing liquid level sensor water resistance is bad.
For achieving the above object, this utility model uses such as purgation technical scheme:
A kind of liquid level sensor PCBA board waterproof construction, includes body, PCBA board, interior plug, outer plug and electric wire；
This body has an accommodation space；This PCBA board is accommodated in accommodation space, and PCBA board has a bonding wire end；This hose lining plug sleeve sets
In PCBA board, bonding wire end protrudes upward interior plug, and interior plug closely cooperates with the inwall of accommodation space；This outer plug covers
The upper end open of accommodation space, is formed with sealing space, is filled with fluid sealant in sealing space between outer plug and interior plug, front
State bonding wire end to be embedded in fluid sealant；This electric wire welds conducting through outer plug with bonding wire end.
As a kind of preferred version, described fluid sealant is transparent adhesive tape.
As a kind of preferred version, the lower end of described outer plug is inserted in accommodation space and tight with the inwall of accommodation space
Coordinating, the upper end of outer plug is exposed outside body.
This utility model compared with prior art has clear advantage and beneficial effect, specifically, by above-mentioned technology
Scheme understands:
By the sealing space filling with sealant formed between plug outside and interior plug, and it is close to coordinate bonding wire end to be embedded in
In sealing, the liquid come in along electric wire can be stopped, prevent liquid from entering into body internal corrosion electronic original part, water resistance
Good, serve the effect of well protection.This utility model has simple in construction, is easy to advantages such as producing, with low cost, also can
Playing the effect preventing conductor vibration from rupturing, product serviceability is more preferably.
For more clearly illustrating architectural feature of the present utility model and effect, it is right to come with specific embodiment below in conjunction with the accompanying drawings
This utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of the preferred embodiment of this utility model；
Fig. 2 is the close-up schematic view of Fig. 1；
Fig. 3 is the view being not filled by fluid sealant in Fig. 2.
Accompanying drawing identifier declaration:
10, body 11, accommodation space
12, space 20, PCBA board are sealed
21, bonding wire end 30, interior plug
40, outer plug 50, electric wire
60, fluid sealant.
Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 3, that show the concrete structure of the preferred embodiment of this utility model, include
Body 10, PCBA board 20, interior plug 30, outer plug 40 and electric wire 50.
This body 10 has an accommodation space 11；In the present embodiment, described body 10 is PP material, but does not limit to PP material
Matter, it is also possible to for other materials.
This PCBA board 20 is accommodated in accommodation space 11, and PCBA board 20 has a bonding wire end 21.
This interior plug 30 is sheathed in PCBA board 20, and bonding wire end 21 protrudes upward interior plug 30, interior plug 30 and accommodating sky
Between 11 inwall closely cooperate.
This outer plug 40 covers the upper end open of accommodation space 11, is formed with sealing between outer plug 40 and interior plug 30
Space 12, is filled with fluid sealant 60 in sealing space 12, and aforementioned bonding wire end 21 is embedded in fluid sealant 60；In the present embodiment,
Described fluid sealant 60 is transparent adhesive tape, but is not limited to transparent adhesive tape, it is also possible to for the fluid sealant of other materials.Further, described outer glue
The lower end of plug 40 is inserted in accommodation space 11 and closely cooperates with the inwall of accommodation space 11, and body is exposed in the upper end of outer plug 40
Outside 10.
This electric wire 50 welds conducting through outer plug 40 with bonding wire end 21.
During making, first, interior plug 30 is assembled in PCBA board 20, then, by electric wire 50 when producing PCBA board 20
Through outer plug 40 and weld conducting with bonding wire end 21, then PCBA board 20 is first pre-assembled in body 10；Then, by fluid sealant
Bonding wire end 21 in PCBA board 20, to the bonding wire end 21 of PCBA board 20, is sealed by 60 embeddings, then by the outer glue on electric wire
Plug 40 is assembled on body 10 so that the upper end open sealing column of body 10, operation completes.
The liquid come in along electric wire can be stopped by this utility model, prevents liquid from entering into body internal corrosion former to electronics
Part, plays the effect of protection.This utility model has simple in construction, is easy to advantages such as producing, with low cost, also can play and prevent
The effect of conductor vibration fracture.
The above, be only preferred embodiment of the present utility model, not make technical scope of the present utility model
Any restriction, thus every according to technical spirit of the present utility model, above example is made any trickle amendment, equivalent become
Change and modify, all still falling within the range of technical solutions of the utility model.
