Abstract
The invention discloses a method for mounting a circuit board of an electronic water meter, which comprises the following steps of: singly mounting a cavity on the top of a character-wheel box of the electronic water meter; placing the circuit board of the electronic water meter in the cavity and fixing the circuit board at the upper end of the cavity; mounting a top plate on the circuit board; and drilling a through hole in the position on the top plate, which corresponds to the figure display of a character wheel, wherein the through hole is convenient for a character of the character wheel to display. The top plate is a non-transparent top plate and covers the circuit board to reduce the influence of light rays on the circuit board. The invention provides a brand new way for mounting the circuit board. The circuit board is installed on the top of the character wheel of the water meter, which prevents the circuit fault caused by long-term contact between the circuit board and water and ensures the mounting and production are simpler and more convenient and accurate by positioning through the positioning hole.
Description
One. technical field: the present invention relates to a kind of installation method of circuit board, particularly relate to a kind of installation method of circuit board of electronic water meter.
Two. background technology: at present, the installation of circuit board of electronic water meter generally has following dual mode: 1, make independent cavity below the water meter character wheel, circuit board is sealed in this inside cavity; 2, make independent cavity in water meter character wheel upper side, circuit board is installed on this inside cavity.First kind of mode is because the disposable sealing of circuit board is installed in water meter character wheel below, owing to for a long time with the water contact, still have steam and enter circuit board, fault appears easily, and when fault occurring, can only the integral replacing water meter, cause the maintenance cost costliness; Second way circuit board is installed in the character wheel side, uses slot that circuit board is carried out stationkeeping, and this method is not easy accurately to grasp the position aborning, and is subject to vibration influence in transportation, and then influences measuring accuracy, and competitiveness of product is reduced.
Three. the content of invention:
Technical matters to be solved by this invention is: overcome the prior art deficiency, provide a kind of simple and practical, can avoid because of contact the installation method that causes fault and locate accurate circuit board of electronic water meter with water.
The technical scheme that the present invention is taked for the technical solution problem is:
A kind of installation method of circuit board of electronic water meter, character wheel box top at electronic water meter is provided with a cavity separately, the circuit board of electronic water meter is placed in this cavity, and, this circuit board is fixed on the upper end of described cavity by pilot hole, a top board is set above described circuit board, and the position that corresponding wheel digital shows on this top board offers through hole, and being convenient to the character wheel character can show.
Described circuit board is connected with described cavity is movable by screw, perhaps is fixed together by gluing.
Described top board is opaque top board and covers described circuit board, to reduce the influence of light for circuit board; Described top board and described character wheel box screw retention or gluing fixing.
Positive beneficial effect of the present invention is:
1. the present invention proposes a kind of mode of brand-new mounting circuit boards, make circuit board be installed in water meter character wheel top, not only avoid circuit board because of contacting for a long time the fault that causes, and by by the pilot hole location with water, make install when producing easier, accurate.
2. the present invention installs opaque top board at the cavity top, only in the display part perforate of corresponding wheel digital, the character wheel character can be shown, and this top board covering board reduces the influence of light for circuit board, to improve measuring accuracy, increases the service life.
3. the present invention is simple and practical, easy to implement, and it is applied widely, has good economic and social benefit after the popularization.
Four. embodiment:
Embodiment: the character wheel box of existing electronic water meter all is provided with the character wheel chamber, character wheel and transmission shaft all are installed in the character wheel chamber, the present invention is that the top of character wheel box is provided with a cavity separately on the top in character wheel chamber, circuit board with electronic water meter is placed in this cavity then, and this circuit board is fixed on the upper end of cavity by pilot hole, in addition, a top board is set above circuit board, and the position that corresponding wheel digital shows on this top board offers through hole, and being convenient to the character wheel character can show.
Circuit board is connected by screw and cavity are movable, also can be fixed together by gluing, determines as required.In addition, top board is opaque top board and covering board, to reduce the influence of light for circuit board; Top board and character wheel box screw retention or gluing fixing.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
