The intelligentized functions such as the bidirectional data communication function of kind of data-transmission mode, anti-stealing electricity function, in urban construction by
It is more and more to use, to adapt to the use of modern smart grid and new energy.
In general, the shell of intelligent electric meter in the prior art includes lower case and upper housing, lower case and upper casing
Body fission forms and can be carried out combination, more demanding to sealing waterproof and dustproof, antistatic after the shell combination of ammeter, to obtain
One good sealing space fixes electronic circuit sensing element to guarantee its normal work.Under traditional intelligent ammeter shell
Connection buckle is generallyd use between shell and upper housing or screw carries out assembly connection, and link position needs to increase there are gap
Add additional sealing ring to realize sealing, nonetheless, there is no guarantee that sealing effect.
Utility model content
The technical issues of the utility model is solved is to provide a kind of ammeter shell Hermetical connecting structure, above-mentioned to solve
The defects of technical background.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of ammeter shell Hermetical connecting structure, including upper housing and lower case lead between the upper housing and lower case
It crosses one of fastener, plug connector, threaded connector or several combinations is attached, set on the periphery of the lower case
It is equipped with convex rank, and there are ultrasonic bond wiring on the outside of convex rank, fluted, and the card holding trough is set on the top surface of the convex rank
The block tongue being oppositely arranged with groove is then provided on corresponding surface；And the upper housing includes the snapping side snapped onto lower case,
The snapping is while for L shape, and the outer rim face ultrasonic welding line position on the L shape side, in addition, being provided on the inside of the snapping side
The card holding trough to match with convex rank, meanwhile, there are a gasket slots for the outer rim of respective slot on upper housing, and in the sealing
A J-type gasket is packaged in pad slot.
As a further improvement, the section of the groove is V-arrangement.
As a further improvement, pad is equipped with the gasket of a strip, the strip gasket following table in the groove
Face matches with groove, and upper surface matches with block tongue.
As a further improvement, the section of the block tongue is wedge surface, gore or trapezoidal faces.
The utility model has the advantages that upper housing and lower casing of the ammeter shell Hermetical connecting structure of the utility model to intelligent ammeter shell
Body outer rim edge junction is redesigned, and is sealed with J-type gasket, the convex rank position of upper housing by block tongue with
Groove strip gasket is cooperated to increase the decrement of partially sealed circle, so that sealing structure position be made to be threadedly coupled
Part at least one in rearward recess strip gasket and J-type gasket in place that be screwed on is in complete stitching state, close to improve
Sealing property and sealing effect, meanwhile, a ultrasonic bond wiring is additionally provided in the outer rim of convex rank to reduce the weldering of interface position
Seam, to further increase sealing performance.
