Abstract
The invention relates to an electronic water meter which can inhibit leaking of a filling agent towards one side of a control part. The solution is that a notch (61) extending outwards forms in a hole (6a) of a dial plate (6) sticking to the back surface of a window (4), and the periphery (62) of the hole (6a) is made to be bendable. Thus the diameter of the hole (6a) can be made to be small without reducing assembling performance, and the filling agent in a gap between a hole (4a) of an inlet window (4) and a communication terminal (8) will not easily pass through the hole (6a). The periphery (62) of the hole (6a) is abutted against a rib (12). The abutted portions can block flowing of the filling agent.

Embodiment
Example 1
Fig. 1 is the sectional stereogram of the electric water meter of the invention process form 1.And Fig. 2 is sectional view when cutting off electric water meter in the position of the A-A line shown in Fig. 1.In Fig. 2, following communication terminal 8 and rib 12 adopt plan representation.
In electric water meter, be shaped with the inside of the screening water receptacle 1 of bottom tube-like at resin, accommodate the electronic component protection container 2 being similarly bottom tube-like made of copper.And in the inside of electronic component protection container 2, accommodate by LCD (liquid crystal display) 3a, substrate (not shown), battery (not shown) and support the control part 3 that the resin-made support (not shown) etc. of these LCD3a, substrate, battery is formed.The impeller rotated by means of current and the permanent magnet (not shown) being installed on this impeller are set below the paper of screening water receptacle 1.In the inside of electronic component protection container 2, be provided with the Magnetic Sensor (not shown) of the changes of magnetic field detecting this permanent magnet, based on the output of Magnetic Sensor, calculate the water yield with the substrate of control part 3.Operation result is shown in LCD3a.
The paper upper end of electronic component protection container 2 utilizes the window 4 be made up of discoideus glass plate to close.Window 4 be arranged at state that electronic component protects the grade surface 2a of the inner peripheral surface of container 2 to clip the elastic components 5 such as O shape ring under be fixed wtih by bending pawl 2b, therefore electronic component protection container 2 keeps airtight conditions.On the face (back side) of the electronic component protection inner side of container 2 of window 4; paste by having that flexual material, such as vinyl chloride etc. forms, the index dial (board member) 6 of the unit of the water yield that note has the model of electric water meter, electric water meter is measured etc.The central portion of index dial 6 forms big uncork, and LCD3a exposes from this opening.According to the unit of the water yield of record on the operation result that LCD3a shows and index dial 6, user can know the use amount etc. of water.
The recess 1b that the upper surface 1a of the paper of screening water receptacle 1 is formed is embedded with the bottom 7a on the paper of resinous screening water receptacle cover 7, screening water receptacle 1, electronic component protection container 2 and screening water receptacle cover 7 are assembled.Hide on the cover 7b of water receptacle cover 7, be formed with user and watch the display peristome 7c of index dial 6 and LCD3a by window 4 and the installation peristome 7d of following filling containers 10 is installed.
Be formed with 4 hole 4a at window 4,4 communication terminal 8 extended from the substrate of control part 3 are outstanding to the outside of electronic component protection container 2 respectively by hole 4a.The top of the communication terminal 8 outstanding to the outside of electronic component protection container 2 is connected with cable 9; this connecting portion of communication terminal 8 and cable 9, by the filling containers 10 of box of the upper installation of the upper installation peristome 7d formed of cover 7b that hides water receptacle cover 7 and the surface of window 4 surround.The inside of the filling containers 10 that installation peristome 7d installs, thinks and blocks for the purpose of water etc. inside and outside electric water meter, be filled with the filling agent of the insulativity be such as made up of resin from filling orifice 10a.
Further, cable 9 is drawn towards the outside of filling containers 10, can be sent to outside in data such as the water yields that the substrate of control part 3 calculates by communication terminal 8 and cable 9.
In order to make communication terminal 8 give prominence to from the interior of electronic component protection container 2 like this, first the control part 3 being provided with communication terminal 8 being loaded electronic component protection container 2 inner, then covering the window 4 being pasted with index dial 6.At this moment, communication terminal 8 is inserted the hole 4a of window 4.Thereafter, electronic component is utilized to protect the bending pawl 2b of container 2 fixed by window 4 and assemble.
Fig. 3 is the important part amplification stereogram near the 4a of hole.The index dial 6 of window 4 and stickup on it is with cross section state representation.Index dial 6 utilizes the double-faced sticking paper 11 represented with cross section to be equally pasted onto on the back side of window 4.Other pasting hacks such as bonding agent can also be utilized to paste index dial 6.Communication terminal 8 is through to be on one side arranged at the resinous rib 12 of the support of control part 3 and to be supported by rib 12, inserting hole 4a.
Here, the planimetric map shown in Fig. 4 is the figure of a part for the planimetric map extracting index dial 6 out.Specifically, the part being positioned at rib 12 periphery shown in Fig. 3 is extracted out.Index dial 6 is formed 4 make communication terminal 8 by hole 6a.
Hole 6a is formed with at substantially equal intervals 4 slit-shaped otch 61 extended to its periphery.Further, otch 61 is not limited to 4, can suitably arrange individual arbitrarily.By forming otch 61, the peripheral part 62 of hole 6a forms the state that can work as flexure strip.
Fig. 5 represents the situation of observing Fig. 3 from the B direction Fig. 3.The end (bottom of paper) of index dial 6 side of the hole 4a that window 4 is formed is more toward top, and the diameter in hole is larger, and in other words, the cross section of the window 4 of the surrounding of the bottom of hole 4a forms taper.Index dial 6 is glued to the back side of window 4 under the state that hole 6a is opposed with hole 4a.The through rib 12 of communication terminal 8 is projections being roughly cylinder that top forms taper, and its external diameter is larger than the diameter of the hole 6a that index dial 6 is formed.
According to these situations; hole 4a and hole 6a is extended and the communication terminal 8 of through rib 12 is opposed with the substrate from control part 3; and the window 4 of dish 6 with a scale and electronic component are protected the grade surface 2a of container 2 to clip elastic component 5 ground to be assembled in electronic component when protecting container 2; as shown in Figure 5; the peripheral part 62 of hole 6a abuts with rib 12 and is pushed to window 4 side, forms case of bending.Because the peripheral part 62 of hole 6a is bending like this, even if the diameter of reduction holes 6a, be assembled in communication terminal 8 also can not to hole 6a makes troubles.Thus, natively can the diameter of reduction holes 6a by forming otch 61, therefore, for the filling agent from the gap between the inner ostium 4a of filling containers 10 and communication terminal 8, the hole 6a of index dial 6 is just not easy have passed through.And the peripheral part 62 of hole 6a abuts with rib 12, in the constricted flow of abutting portion filling agent.
Consider different from the hole 6a shown in Fig. 4, as a reference example shown in Fig. 8, do not have the pure circular port 6b of otch 61 to be formed at the situation of index dial 60.In this case, the peripheral part of hole 6b is not easy as the peripheral part 62 of hole 6a bending, if therefore consider the skew that the position forming hole 6b hole when 6b on index dial 60 occurs, the key element position skew of assembly error when substrate mounting is on the support of control part 3, namely communication terminal 8 etc. being formed obstacle when communication terminal 8 passes hole 6b, be necessary the diameter design of hole 6b to obtain more greatly, allow some leeway.That is, the diameter of hole 6b must be larger 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.
Like this on index dial 60 when the circular hole 6b of simplex, the filling agent putting into filling containers 10 inside will behind the gap between ostium 4a and communication terminal 8, through hole 6b and communication terminal 8, between hole 6b and rib 12, flow out to control part 3 side below index dial 60.
By contrast; in the electric water meter of the example 1 of the invention described above; index dial 6 is formed the hole 6a with the shape of the otch 61 shown in Fig. 4; the deviation of the forming position of the hole 6a when window 4 of dish 6 with a scale being assembled in electronic component protection container 2 on debatable, index dial 6, be assembled in control part 3 support on time communication terminal 8 position deviation etc.; the bending of peripheral part 62 of hole 6a can be utilized to dissolve, therefore can the diameter of hole 6a be done little.By doing little by the diameter of hole 6a, be just not easy the gap of the hole 6a through index dial 6 from the filling agent in the gap between the inside ostium 4a and communication terminal 8 of filling containers 10.Again, the peripheral part 62 of hole 6a abuts with rib 12, and in abutting portion, the flowing of filling agent is prevented from.That is, the situation that filling agent flows out to control part 3 side below index dial 6 is inhibited, and the leakage of filling agent is inhibited.
Again, when index dial 6 is positioned between control part 3 and window 4 with free state, filling agent can by flowing to paper transverse direction between the back side of window 4 and the surface of index dial 6 and leaking to control part 3 side, but as mentioned above, by index dial 6 being pasted onto the back side of window 4, can prevent filling agent from passing through such path to the flowing of paper transverse direction, leakage.
Again, by the hole 4a of window 4 being made diameter in the bottom shape larger than the diameter at the position beyond bottom, rib 12 and the contact of window 4, to abut with rib 12 and all can not be occurred by the contact of the peripheral part 62 of the hole 6a to window 4 one thruster and window 4.Thus, the situation that stress causes window 4 to break is continuously applied to the window 4 of glass manufacture and also can not occurs.Further, in order to this object, the shape of hole 4a is not limited to the shape shown in Fig. 5, and also can be the grade surface 41 that inner peripheral surface has such as shown in Fig. 6, bottom be large-diameter portion, and the position beyond bottom is the such shape of minor diameter.
But, particularly as shown in Figure 5, the diameter of the bottom of hole 4a is formed as more larger toward top, the top of rib 12 is formed as taper, thus, the window 4 of the surrounding of the bottom of hole 4a is thin must exceed needs thus the situation that Strong degree reduces would not occur, and the peripheral part 62 of hole 6a can not be made to bend, to be accommodated well with applying stress to window 4
The hole 6a shown in Fig. 4 can also be replaced, index dial 6 is formed the hole 6c shown in Fig. 7.
On the 6c of hole, form the otch 63 that 4 outsides to this circumference extend at substantially equal intervals.Further, otch 63 is not limited to 4, also suitably can be set as arbitrary number.And from the top that the otch 63 on the 6c of hole is respective, bifurcated forms the otch 64 along the concentrically ringed arc-shaped of hole 6c.
The situation of hole 6c is also the same with hole 6a, and when the window 4 with index dial 6 being assembled in electronic component protection container 2, the peripheral part 65 of hole 6c abuts with rib 12 and is pushed to window 4 side, forms case of bending.That is, the same with hole 6a, hole 6c also can be formed filling agent be not easy through minor diameter, and don't bring inconvenience to assembling, again, peripheral part 65 abuts with rib 12, and abutting portion can stop the flowing of filling agent.Thus, filling agent can be suppressed to flow out to control part 3 side below index dial 6, the leakage of filling agent can be suppressed.Further, the peripheral part 65 of hole 6c is also easy to be more bending than the peripheral part 62 of hole 6a, therefore by using hole 6c, can improve the assembling property being assembled in communication terminal 8 further.
Again, above described in, by forming hole 6a, 6c on the index dial 6 of unit etc. recording the water yield, form the structure of function of leakage that index dial 6 has scale function and suppresses filling agent.But index dial 6 also can be adopted to form hole 6a, 6c and do not possess the simple seal pad of scale function, scale function transfers to LCD3a, forms the structure of the unit being shown the water yield by LCD3a etc.Or also can replace the index dial 6 of function of the leakage having scale function concurrently and suppress filling agent, replace the index dial that arranges respectively and there is scale function and formed by hole 6a, 6c and have the seal pad of the function of the leakage suppressing filling agent structure.
Again, existing structure is that rib 12 is arranged on the support of support LCD3a, substrate, battery, but also can be arranged on another component beyond support, is placed in electronic component protection container 2.And, as long as rib 12 can abut with the peripheral part 62 of hole 6a and to window 4 one thruster, be not picture as shown in Figure 6 top be that taper also has no relations.
Again, represent in figure that portal 4a, hole 6a, hole 6c, rib 12 respectively arrange 4, but be not limited to these numbers, suitably should design according to the number of communication terminal 8 certainly.
As mentioned above, if adopt the electric water meter of the invention process form 1, owing to being formed with peripheral part 62,65 bending hole 6a, 6c on index dial 6, therefore, it is possible to do little by the diameter of hole 6a, 6c, and do not affect the assembling property being assembled in communication terminal 8.Thus, be just not easy the gap of hole 6a, 6c through index dial 6 from the filling agent in the gap between the inside ostium 4a and communication terminal 8 of filling containers 10, and peripheral part 62,65 abuts with rib 12, abutting portion can stop the flowing of filling agent.Thus filling agent can be suppressed to flow out to control part 3 side below index dial 6, suppress the leakage of filling agent, therefore problem is less likely to occur for the water tolerance of electric water meter and insulativity.And the surface that filling agent is diffused into the LCD3a of control part 3 is less likely to occur causes the measurement result of the water yield to be not easy situation about seeing.
Again, the hole 4a of window 4 is made into that it is more larger toward top at the diameter of the end of index dial 6 side, and rib 12 forms taper towards index dial 6.Thus the window 4 of the surrounding of the bottom of hole 4a is thin must exceed needs thus the situation that Strong degree reduces can not occur, and the peripheral part 62,65 of hole 6a, 6c can not be made to bend, to be accommodated well with applying stress to window 4.
Again, from the top of the otch 63 that the hole 6c of index dial 6 is formed, bifurcated forms the otch 64 along the concentrically ringed arc-shaped of hole 6c.Thus, more can be held flexible peripheral part 65, the assembling property being assembled in communication terminal 8 can be improved further.
Further, within the scope of the invention, the omission of the distortion of the arbitrary structures key element of example or the arbitrary structures key element of example is all possible in the invention of the application.
