Abstract
The utility model relates to a current sensor comprising an insulating housing, wherein the housing is provided with a recessed chamber, an iron core is arranged inside the recessed chamber, and the outer portion of the iron core is coated by a coil. The current sensor is characterized in that: the recessed chamber is filled up with epoxy resins, a gland is arranged at the jaw opening of the recessed chamber on the housing, and the portion between the gland and the housing is fixedly sealed. According to the technical scheme, the provided current sensor may not only enable excellent positioning of the iron core, but also exert no effect on the magnetic conduction performance of the iron core.
Description
Technical field
The utility model relates to a kind of current sensor.
Background technology
Existing a kind of current sensor includes insulation crust, shell is that silicon rubber is made, described shell is provided with cavity, is provided with iron core in the cavity, iron core is coated with coil, adds man-hour, under hot conditions, iron core directly is pressed in the shell, still, owing to add temperature height in man-hour, can cause bigger influence to the magnetic property of iron core, thereby make the big heavy discount of performance of current sensor.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of current sensor, and it can be located iron core well, can not influence the magnetic property of iron core again.
The technical solution of the utility model: a kind of current sensor, include insulation crust, described shell is provided with cavity, be provided with iron core in the cavity, iron core is coated with coil, it is characterized in that: be filled with epoxy resin in the described cavity, be positioned at the cavity opening part on the described shell and be provided with gland, fixing seal between described gland and the described shell.
Adopt technique scheme, by the epoxy resin of in cavity, filling, can locate iron core well, can not influence the magnetic property of iron core again; Fixing seal between gland and the described shell can prevent that introduced contaminants from entering the interior current sensor serviceability that influences of cavity.
Further setting of the present utility model: described cavity bottom arranges reference column, and described iron core sleeve is located on the described reference column.
Adopt above-mentioned further setting, by the reference column that arranges, can further locate iron core, thereby make that the iron core location is more reliable.
Of the present utility modelly further arrange again: between described gland and the described shell through the silicon rubber fixing seal.
Adopt above-mentioned further setting again, the gland of this structure and shell fixing seal, simple in structure, good sealing effect, and, can make that the location is reliable between gland and the shell.
Further setting of the present utility model: described gland sidewall is outward extended with annular flange flange, and described cavity inwall is provided with annular groove, and described annular flange flange is embedded in described annular groove.
Adopt above-mentioned further setting, annular flange flange, annular groove by arranging can increase the packing surface between gland and the shell, make sealing effectiveness better.
