Button 8, button 8 are silica gel button, and in the present embodiment, button 8 is arranged on case 2.
The utility model embodiment uses same case to being possibly realized on the electric energy meter of two kinds of assembly methods.
The prior art why can not compatible two kinds of cases, be because this assembly method of ultrasonic bonding needs case to increase
Add welding bar, thickness 0.6mm.But if after increasing welding bar on non-ultrasonic case, thickness increase after assembling can be caused
0.6mm, so that a series of problems is caused, such as dustproof and waterproof, button height change etc..
The mode of case 2 and bottom case 1 the connection installation of this programme has two kinds, and one kind is that both are connected to one using screw
Rise, another kind is exactly the mode using ultrasonic bonding.When by the way of screw, then need to be put into sealing in groove 31
Circle 7, such chimb 42 are inserted into groove 31, sealing ring 7 are then compressed, so as to fulfill sealing effect；If using ultrasonic bonding
Mode, then sealing ring 7 can be with can not have to, in this manner, and ultrasonic bonding muscle 41 can be by 4 He of upper connecting portion of case 2
The lower connecting portion 3 of bottom case 1 connects.
The utility model employs two kinds of connection mode, and therefore, the requirement to button just improves.Because supersonic welding
Connecing this assembly method needs the welding bar of case increase thickness 0.6mm, thus by the way of ultrasonic bonding compared to
Using engagement thread, the case 2 of the present apparatus can sink some distances, therefore, the button phase used in the ammeter structure of the present apparatus
For in common ammeter structure be completely it is different, in order to solve the problem above-mentioned, by button in the present embodiment
Silica gel button is arranged to, since silica gel is that have excellent elasticity, in the case where causing case 2 using ultrasonic bonding mode
Heavy, after causing silica gel button compression, silica gel button can still work normally.
The pervious single electric energy meter structure using ultrasonic bonding, its welding bar are directly arranged on case base
, so may result in ultrasonic bonding, whole case 2 receives influence, this result in parts inside case 2 by
To influence.
And the present apparatus sets connecting portion 4, then the connecting portion 3 under the setting of bottom case 1 at the edge of case 2, upper connection is utilized
The mode that portion 4 is connected with lower connecting portion 3, so as to avoid when ultrasonic bond, influencing the parts in case 2 and bottom case 1.
Two kinds of cases are combined into one kind by the present embodiment, solve dustproof and waterproof well, button height and end cap height
Problem, while solve problems with：1) dustproof and waterproof, not when by the way of ultrasonic wave, increases sealing ring；Using super
When sound wave welds, sealing ring is taken away；2) ultrasonic bond and non-ultra-sonic welded case are highly different, cause the Show Button and report of uncapping
Alert ammonium button height is also different, and original mechanical botton is all changed to silica gel button by us, using the elasticity of silica gel, well
Solves the problems, such as this；3) ultrasonic bond and non-ultrasonic bond watch glasses shell are highly different, cause end cap assembling height also different, we
By amplifying the fit clearance between end cap and case, solves the problems, such as this well.
The utility model uses same case, can both realize that ultrasonic bond assembled, and can also have been assembled by screw, therefore
The mould of the case is only secondary with opening one, and stock also only needs standby one kind.
The scope of protection of the utility model includes but not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Subject to sharp claim, any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
The utility model is simple and reliable for structure, and easily manufactured cost is low, can fit while meet screw mode and ultrasonic wave
The assembly method of welding manner, enterprise's production cost reduce, and production efficiency is improved, and greatly facilitate enterprise's production
Stock.
