On the face (back side) of side, paste by there is flexible material, form such as vinyl chloride, note has the type of electric water meter
Number, the dial (board member) 6 of the unit of water etc. that measures of electric water meter.The central portion of dial 6 forms big opening,
LCD3a exposes from the opening.According to the unit of water recorded on the operation result and dial 6 shown on LCD3a, Yong Huke
To know usage amount of water etc..
The screening water container cover 7 of resin is embedded on the recess portion 1b formed on the upper surface 1a of the paper of screening water container 1
Lower end 7a on paper will hide water container 1, electronic component protection container 2 and screening water container cover 7 and be assembled.Hide the water capacity
On the cover 7b of device cover 7, be formed with user by window 4 watch the display of dial 6 and LCD3a with opening portion 7c and
The installation opening portion 7d of following filling containers 10 is installed.
Be formed with 4 hole 4a in window 4,4 communication terminals 8 extended from the substrate of control unit 3 respectively by hole 4a to
External the protruding of electronic component protection container 2.To the top of the external prominent communication terminal 8 of electronic component protection container 2 and
Cable 9 connects, communication terminal 8 and the connecting portion of cable 9, the installation opening formed on the cover 7b of screening water container cover 7
The filling container 10 for the box installed on portion 7d and the surface of window 4 are surrounded.In the installation filling installed on the 7d of opening portion
The inside of container 10 for the purpose of water etc. is blocked inside and outside for electric water meter, is filled with from injection hole 10a and is for example made of resin
Insulating properties filler.
In addition, cable 9 is led to the outside of filling container 10, it can in data such as the waters that the substrate of control unit 3 calculates
To be transmitted to outside by communication terminal 8 and cable 9.
In order to which communication terminal 8 is made to be protruded in this way from the interior of electronic component protection container 2, will be provided with first logical
Believe that the control unit 3 of terminal 8 is packed into inside electronic component protection container 2, then cover the window 4 for being pasted with dial 6.At this moment,
Communication terminal 8 is inserted to the hole 4a of window 4.Thereafter, window 4 is consolidated using the bending pawl 2b of electronic component protection container 2
Determine and assemble.
Fig. 3 is the mian part amplification stereogram near the 4a of hole.Window 4 and the dial 6 pasted thereon are represented with section state.
Dial 6 is pasted onto using the double-faced sticking paper 11 equally represented with section on the back side of window 4.Can also utilize bonding agent etc. its
He pastes dial 6 by pasting hacks.Communication terminal 8 penetrates through the rib 12 and quilt of the resin for the stent for being set to control unit 3 on one side
Rib 12 supports, one side inserting hole 4a.
Herein, plan view shown in Fig. 4 is the figure of a part for the plan view for extracting dial 6 out.Specifically, extraction
Positioned at the part on 12 periphery of rib shown in Fig. 3.Be formed on dial 64 make communication terminal 8 by using hole 6a.
4 slit-shaped notch 61 extended to its periphery are formed on the 6a of hole at substantially equal intervals.In addition, notch 61
4 are not limited to, arbitrary can be appropriately arranged with.By forming notch 61, the formation of peripheral part 62 of hole 6a can be used as elastic piece
The state to work.
Fig. 5 represents the situation of Fig. 3 from the B directions in Fig. 3.The end of 6 side of dial of the hole 4a formed on window 4
More toward top, the diameter in hole is bigger in portion (lower end of paper), and in other words, the window 4 of the surrounding of the lower end of hole 4a is cut
Face forms taper.Dial 6 is glued to the back side of window 4 in a state that hole 6a is opposed with hole 4a.What communication terminal 8 penetrated through
Rib 12 is the generally cylindrical protrusion that top forms taper, and outer diameter is bigger than the diameter of hole 6a formed on dial 6.
According to these situations, hole 4a and hole 6a is made to extend with the substrate from control unit 3 and penetrate through the communication terminal 8 of rib 12
It is opposed, and the grade surface 2a of the window 4 of disk 6 with a scale and electronic component protection container 2 is clipped into 5 ground of elastic component and is assembled in electricity
During sub- part protection container 2, as shown in figure 5, the peripheral part 62 of hole 6a abuts with rib 12 and is pushed to 4 side of window, formed curved
Curved state.Since the peripheral part 62 of hole 6a is bent in this way, even if reducing the diameter of hole 6a, communication ends will not be assembled in hole 6a
Son 8 is made troubles.So as to, can natively reduce the diameter of hole 6a by forming notch 61, therefore, for from filling container 10
For the filler in the gap between internal ostium 4a and communication terminal 8, the hole 6a of dial 6 is just not easy to have passed through.And
And the peripheral part 62 of hole 6a is abutted with rib 12, in the constricted flow of abutting portion filler.
Consideration is different from hole 6a shown in Fig. 4, shown in Fig. 8 as a reference example, without the pure circle of notch 61
Shape hole 6b is formed in the situation of dial 60.In this case, the peripheral part of hole 6b be not easy as hole 6a peripheral part 62 that
Sample be bent, so if in view of on dial 60 formed hole 6b when hole 6b position occur offset, by substrate mounting in
The position offset of assembly error when on the stent of control unit 3, namely communication terminal 8 is when communication terminal 8 passes through hole 6b
If the element for forming obstacle, it is necessary to the diameter design of hole 6b be obtained more greatly, allowed some leeway.That is, hole 6b's is straight
Diameter must be bigger than the diameter of hole 6a, between hole 6b and communication terminal 8 and between hole 6b and rib 12, just forms larger gap.
At this moment situation is shown in Fig. 9 as the comparison other with Fig. 5.
In the case of forming round hole 6b merely on dial 60 in this way, be put into filling container 10 inside filler just
Behind gap that can be between ostium 4a and communication terminal 8, across hole 6b and communication terminal 8, between hole 6b and rib 12, to
3 side of the control unit outflow of 60 lower section of dial.
In contrast, in the electric water meter of the implementation form 1 of the invention described above, being formed on dial 6 has Fig. 4 institutes
The hole 6a for the shape of notch 61 shown, problematic, the quarter when window 4 of disk 6 with a scale is assembled in electronic component protection container 2
The deviation of the forming position of hole 6a on scale 6 is assembled in position deviation of communication terminal 8 etc. when on the stent of control unit 3, can
To be dissolved using the bending of the peripheral part 62 of hole 6a, therefore the diameter of hole 6a can be made small.By the way that the diameter of hole 6a is done
Must be small, just it is not easy across scale from the filler in the gap between the filling inside ostium 4a of container 10 and communication terminal 8
The gap of the hole 6a of disk 6.Also, the peripheral part 62 of hole 6a is abutted with rib 12, in abutting portion, the flowing of filler is prevented from.
That is the situation that 3 side of control unit of filler to 6 lower section of dial is flowed out is inhibited, the leakage of filler is pressed down
System.
Also, in the case where dial 6 is positioned over free state between control unit 3 and window 4, filler can pass through
It flows to paper transverse direction between the back side of window 4 and the surface of dial 6 and is leaked to 3 side of control unit, but as above institute
It states, by the way that dial 6 to be pasted onto to the back side of window 4, the path of filler in this way can be prevented to paper transverse direction stream
Dynamic, leakage.
It is also, than the diameter at the position other than lower end bigger by the way that the hole 4a of window 4 to be made to the diameter in lower end
Shape, the contact with window 4 of rib 12 are abutted with rib 12 and by the peripheral part 62 of hole 6a that 4 side of window pushes away and connecing for window 4
Touching will not all occur.So as to which the situation that stress is continuously applied to the window 4 of glass manufacture causes window 4 to rupture will not occur.
In addition, for this purpose, the shape of hole 4a is not limited to shape shown in fig. 5 or inner peripheral surface has for example shown in Fig. 6
Grade surface 41, lower end is major diameter portion, and the position other than lower end is shape as minor diameter.
But particularly as shown in figure 5, the diameter of the lower end of hole 4a is formed as bigger more toward top, by rib 12
Top is formed as taper, as a result, the window 4 of the surrounding of the lower end of hole 4a it is thin be more than need so as to strength reduction situation just
It will not occur, the peripheral part 62 of hole 6a can not be bent with applying stress window 4, to be accommodated well
Hole 6a shown in Fig. 4 can also be replaced, hole 6c shown in Fig. 7 is formed on dial 6.
On the 6c of hole, the notch 63 that 4 outsides to the circumference extend is formed at substantially equal intervals.In addition, notch 63 is unlimited
In 4, can also suitably set as arbitrary number.Moreover, from the 63 respective top of notch on the 6c of hole, bifurcated formed along
The notch 64 of the arc-shaped of the concentric circles of hole 6c.
The situation of hole 6c is also as the 6a of hole, when the window 4 with dial 6 is assembled in electronic component protection container 2,
The peripheral part 65 of hole 6c abuts with rib 12 and is pushed to 4 side of window, forms flexuosity.That is, as the 6a of hole, hole
6c can also be formed filler be not easy across minor diameter, and do not bring inconvenience to assembling, also, peripheral part 65 is supported with rib 12
It connects, abutting portion can prevent the flowing of filler.Thus, it is possible to inhibit filler to 3 side of control unit of 6 lower section of dial
Outflow, can inhibit the leakage of filler.In addition, the peripheral part 65 of hole 6c than hole 6a peripheral part 62 also than be easily bent, because
This can further improve the assembling property for being assembled in communication terminal 8 by using hole 6c.
Also, in described above, hole 6a, 6c are formed on the dial 6 of the unit of water etc. by having in record, forms scale
Disk 6 has the function of scale and inhibits the structure of the function of the leakage of filler.But it is also possible to hole is only formed using dial 6
6a, 6c are transferred to LCD3a without having the simple sealing plate of scale function, scale function, are formed and show water by LCD3a
The structure of unit etc..Or the dial 6 of the function of leakage for having scale function concurrently and inhibiting filler can also be replaced, instead of
To set the dial with scale and formation respectively by hole 6a, 6c and there is the close of the leakage for inhibiting filler
The structure of sealing plate.
It is set on the stent for supporting LCD3a, substrate, battery, but can also be set to also, existing structure is rib 12
On another component other than stent, it is placed in electronic component protection container 2.Moreover, as long as rib 12 can be with the peripheral part of hole 6a
62 abut and are pushed away to 4 side of window, are not as top also has no relations for taper as shown in Figure 6.
Also, representing 4a, hole 6a, hole 6c, rib 12 respectively setting 4, but be not limited to these numbers of portalling in figure, certainly should
It is appropriately designed according to the number of communication terminal 8.
If as described above, using the electric water meter of implementation form 1 of the present invention, due to outside being formed on dial 6
Hole 6a, 6c that circumference 62,65 is bent, therefore the diameter of hole 6a, 6c can be made small, and do not influence to be assembled in communication terminal
8 assembling property.As a result, from the filler in the gap between the filling inside ostium 4a of container 10 and communication terminal 8 just not
The gap of hole 6a, 6c of dial 6 are easily propagated through, and peripheral part 62,65 is abutted with rib 12, abutting portion can prevent filler
Flowing.Thus, it is possible to which 3 side of control unit for inhibiting filler to 6 lower section of dial is flowed out, inhibit the leakage of filler, because
Problem is less likely to occur the water resistance and insulating properties of this electric water meter.And filler is less likely to occur and is diffused into control unit 3
The surface of LCD3a lead to the situation that the measurement result of water is not easily seen.
Also, the diameter that the hole 4a of window 4 is made into its end in 6 side of dial is bigger more toward top, rib 12 towards
Dial 6 forms taper.So as to which the window 4 of the surrounding of the lower end of hole 4a is so thin that be more than situation about needing so as to strength reduction
It will not occur, the peripheral part 62,65 of hole 6a, 6c can not be bent with applying stress window 4, to be received well
Hold.
Also, the top of notch 63 formed from the hole 6c of dial 6, bifurcated forms the circular arc of the concentric circles along hole 6c
The notch 64 of shape.Thus, it is possible to the peripheral part 65 being easily bent, can further improve and be assembled in communication terminal 8
Assembling property.
In addition, present invention is within the scope of the invention, the deformation or implementation of the arbitrary structures element of implementation form
The omission of the arbitrary structures element of form is all possible.
