Abstract
The utility model discloses a kind of location structure of current transformer screening cover, including plastic cover plate, several positioning convex points on the plastic cover plate, metallic shield cover plate compatible with the plastic cover plate, on the metallic shield cover plate and the location hole of the corresponding positioning convex point, the plastic cover plate welds together with the metallic shield cover plate, and the positioning convex point is embedded in the location hole.The utility model overall structure is simple, easily operated.Plastic cover plate is positioned, can be placed in the middle by metallic shield cover plate, anti-shield effectiveness is more preferable；Anti- leak-stopping puts shielding plastic cover board, and has foolproof function；Metallic shield cover plate and plastic cover plate are into a single integrated structure by ultrasonic bonding group, do not have to secondary operation, improve efficiency.
Description
Technical field
The utility model relates to current transformer field more particularly to a kind of location structures of current transformer screening cover.
Background technique
Current transformer includes iron core, coil and shell, and shell is coated on iron core and coil outer, in assembling in order to anti-
High-intensity magnetic field interference, it will usually add a metallic shield cover plate.Existing current transformer circle prevents strong magnetic class product, is that will first produce
Glue is squeezed into inside product, then metallic shield cover plate is put into shell, then fills one layer of glue to fix, finally by plastic cover plate lid
On.This design is that process separates first, shows slightly cumbersome；Followed by increase the risk that shielding plastic cover board is put in leakage；Last gold
Generation can be had the gap between shielding cover plate and shell by belonging to, and influence to prevent strong magnetic function.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of positioning knot of current transformer screening cover
Structure.
The technical solution of the utility model is as follows：A kind of location structure of current transformer screening cover is provided, including：Plastics
Cover board, metallic shield cover plate compatible with the plastic cover plate, is set to several positioning convex points on the plastic cover plate
On the metallic shield cover plate and the location hole of the corresponding positioning convex point, the plastic cover plate and the metallic shield cover plate weld
It is connected together, the positioning convex point is embedded in the location hole.
The plastic cover plate is integrally welded using ultrasonic bonding mode with the metallic shield cover plate.
Using the above scheme, the location structure of the current transformer screening cover of the utility model, overall structure is simple, is easy to
Operation.Plastic cover plate is positioned, can be placed in the middle by metallic shield cover plate, anti-shield effectiveness is more preferable；Anti- leak-stopping puts shielding plastic cover board, and
With foolproof function；Metallic shield cover plate and plastic cover plate are into a single integrated structure by ultrasonic bonding group, do not have to secondary operation, mention
High efficiency.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of location structure of current transformer screening cover referring to FIG. 1 to FIG. 4, including：Plastics
Cover board 1, several positioning convex points 2 on the plastic cover plate 1, metallic shield cover plate compatible with the plastic cover plate 1
3, on the metallic shield cover plate 3 and the location hole 4 of the corresponding positioning convex point 2, the plastic cover plate 1 and the metal
Shielding cover plate 3 welds together, and the positioning convex point 2 is embedded in the location hole 4.
Specifically, described in the positioning convex point 2 on the plastic cover plate 1 being aligned on the metallic shield cover plate 3
Location hole 4, later by two one combined plastic cover boards of synthesis, the metallic shield cover plate 3 up, is put into supersonic mould
In, starting pressing, by two parts firm welding.
The position of the positioning convex point 2 and the location hole 4 can be arbitrarily arranged, and the present embodiment is preferably symmetrical above and below to be set
It sets, quantity preferably two.
In conclusion the location structure of the current transformer screening cover of the utility model, overall structure is simple, is easy to grasp
Make.Plastic cover plate is positioned, can be placed in the middle by metallic shield cover plate, anti-shield effectiveness is more preferable；Anti- leak-stopping puts shielding plastic cover board, and has
There is foolproof function；Metallic shield cover plate and plastic cover plate are into a single integrated structure by ultrasonic bonding group, do not have to secondary operation, improve
Efficiency.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
