Description
Technical Field
The utility model belongs to the technical field of the electromagnetism water gauge, especially, relate to a wire hole for electromagnetism water gauge.
Background
The electromagnetic water meter is a novel intelligent water meter, is widely applied to modern smart cities and DMA (direct memory access) partitioned metering, is suitable for metering of civil water supply main lines and industrial automatic control in application occasions, and has extremely high requirements on the protection level because the use environment comprises the open air, the field, building pipeline wells, underground pipeline wells and the like. At present, most of wire outlet holes of electromagnetic water meters used in the industry are waterproof terminals or glue pouring processes, but both the two protection measures have limitations, for example, the waterproof terminals are difficult to meet the requirement of IP68, and the glue pouring process cannot avoid the invasion of water vapor along a wire core.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide a simple structure, job stabilization, waterproof performance are good, possess the ability of normal work under water for a long time, have avoided causing the wire hole that is used for the electromagnetic water meter of internal circuit trouble because of water, moisture invasion.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a wire hole for electromagnetic water meter, including play spool and waterproof terminal, connect through the connecting pipe between play spool and the waterproof terminal, connecting pipe upper portion outer wall and the inboard wall threaded connection of the spool lower part of being qualified for the next round of competitions, connecting pipe lower part outer wall and waterproof terminal inboard wall threaded connection, the annular boss of spool upper portion inner wall fixedly connected with that is qualified for the next round of competitions, interior outlet plate and the line board of going out of both sides about the inboard fixedly connected with that is located annular boss respectively, be provided with the pad on interior outlet plate and the line board of going out respectively, connect through row's needle electricity between interior outlet plate and the line board of going.
And the connecting pipe is respectively in threaded connection with a first locking nut and a second locking nut, the first locking nut is in top press fit with the lower end of the wire outlet pipe, and the second locking nut is in top press fit with the upper end of the waterproof terminal.
And sealing rings are respectively arranged between the outer wall of the upper part of the connecting pipe and the inner wall of the wire outlet pipe and between the outer wall of the lower part of the connecting pipe and the inner wall of the waterproof terminal.
Adopt above-mentioned technical scheme, the utility model discloses make full use of physical and chemical properties after the embedding glue solidification, the certain waterproof ability that waterproof terminal self possessed, reach the effect of two-layer protection, but furthest's the inside invasion of aqueous vapor edge sinle silk, interior outlet plate, line outgoing plate and casting glue are handled simultaneously, even outside intaking also can guarantee that the product is inside can not intake, consequently improved the protective capacities of product greatly.

Detailed Description
As shown in the figure 1-2, the wire outlet hole for the electromagnetic water meter of the utility model comprises a wire outlet pipe 1 and a waterproof terminal 2, the wire outlet pipe 1 is fixedly connected on the outer shell 3 of the electromagnetic water meter, the wire outlet pipe 1 is connected with the waterproof terminal 2 through a connecting pipe 4, the upper outer wall of the connecting pipe 4 is in threaded connection with the lower inner wall of the wire outlet pipe 1, the lower outer wall of the connecting pipe 4 is in threaded connection with the inner wall of the waterproof terminal 2, the upper inner wall of the wire outlet pipe 1 is fixedly connected with an annular boss 5, an inner wire outlet plate 6 and an outer wire outlet plate 7 which are respectively and fixedly connected with the upper side and the lower side of the annular boss 5 are respectively arranged in the wire outlet pipe 1, the inner wire outlet plate 6 and the outer wire outlet plate 7 are respectively provided with a welding pad, the inner wire outlet plate 6 is electrically connected with the outer wire outlet plate, go out line board 7 and outwards be connected with the sinle silk 9 that stretches out waterproof terminal 2, the intussuseption of outlet pipe 1 is filled with the casting glue. The utility model discloses an interior outlet plate 6 and go out line board 7 and link to each other interior outer circuit, guarantee in time to change outside cable and do not influence inner structure yet.
The connecting pipe 4 is respectively in threaded connection with a first locking nut 10 and a second locking nut 11, the first locking nut 10 is in top-pressing fit with the lower end of the wire outlet pipe 1, and the second locking nut 11 is in top-pressing fit with the upper end of the waterproof terminal 2.
And sealing rings are respectively arranged between the outer wall of the upper part of the connecting pipe 4 and the inner wall of the wire outlet pipe 1 and between the outer wall of the lower part of the connecting pipe 4 and the inner wall of the waterproof terminal 2.
The utility model discloses make full use of the physical and chemical properties after the curing of filling and sealing glue, waterproof terminal 2 self certain waterproof ability that possesses, reach the effect of two-layer protection, but furthest block aqueous vapor along the inside invasion of sinle silk 9, interior outlet plate 6, go out line board 7 and the pouring sealant is handled simultaneously, even outside intaking also can guarantee that the product is inside can not intake, consequently improved the protective capacities of product greatly.
The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification made by the above embodiments.
