Row and mainboard；
The Operation display module is fixed on upper casing topmost, the Operation display module and upper casing, lower casing and button one
Rise and form an annular seal space；Encapsulating shell, mainboard, connecting terminal block and encapsulating frame, institute is fixedly mounted successively from bottom to top in cavity
Stating encapsulating shell is used to support and accommodate mainboard, encapsulating frame and connecting terminal block, it is necessary to which the position of client's wiring is all directed to and connect
On line terminals row；
The height of the connecting terminal block is higher than mainboard, the encapsulating frame height, the encapsulating identical with connecting terminal block
Frame is " day " character form structure, and is respectively equipped with least six vertical partition, the spacing and connecting terminal block of dividing plate in upper and lower two row
The spacing of upper each binding post is identical, and the shape of dividing plate is adapted with connecting terminal block profile, and encapsulating frame is topmost provided with wiring
Indicate note, position and species for indicating wiring；
Further, the Operation display module includes display cover, wiring board, display liquid crystal, key hole and button, described
Wiring board is connected with mainboard by winding displacement transmits signal；The button is connected with wiring board；The display cover is provided with 4 buttons
Hole, for accommodating 4 buttons, each key hole has the edge extended downwardly；Waterproof jacket is provided with inside the key hole,
The waterproof jacket is hat, and the brim of a hat surrounding carries upward flange, and the waterproof jacket height is mutually fitted with the key hole on display cover
Match somebody with somebody, when button is attached on display cover, the brim of a hat of waterproof jacket is lived by the edge side wall and pressure of key hole, reaches the purpose of waterproof.
Further, peak low 0.2-0.5mm of the height of the key hole edge side wall than the button；
Further, after installation, than the display high 0.2-0.5mm of cover top surface at the top of the waterproof jacket；
Further, the encapsulating frame bottom is provided with four prominent buckles, and the mainboard correspondence position is provided with breach,
Buckle can block mainboard, prevent that encapsulating frame from coming off；The vertical partition of above and below withstands connecting terminal block during assembling, prevents from filling
Glue frame vibration, is realized seamless applying between encapsulating frame and connecting terminal block, mainboard.
Mainboard of the present utility model can first carry out overall encapsulating in encapsulating shell, then be attached in main frame, binding post by
Encased in by encapsulating frame, casting glue does not interfere with wiring, after client's wiring, secondary encapsulating can be carried out to improve water resistance.
When client wants to change wiring, note, the fluid sealant more changing-over for corresponding terminal of dismantling can be indicated according to the wiring on encapsulating frame
Line, and the water resistance of other binding posts is not influenceed.
Using the beneficial effect of above scheme：Because Operation display module uses button water-proofing treatment, by improving waterproof
The water resistance of elementary keyboard, to improve the whole machine classification of waterproof of ultrasonic flowmeter, and the increase encapsulating frame at mainboard,
Can the mainboard of encapsulating protection in advance, influence to mainboard when reduction client opens main frame wiring, and when changing some wiring is right
Other wiring not changed can be protected, and can more ensure to change by the vertical partition of wiring indicating sticker and encapsulating frame
The particular location of binding post is can not find during wiring and the casting glue of full wafer is removed, causes mainboard waterproof to be destroyed.
