Description
Technical field
The utility model relates to Hall sensor technical field, especially a kind of current sensor skeleton and current sense
Device.
Background technique
Current sensor is a kind of detection device, separate based on electromagnetic induction, to detect the electric current in route, in electric power
Industry application is extensive.Such as Fig. 1, for a kind of common Hall current sensor, with circular magnet, passing through on magnet has original
Beginning lead, the side of magnet form notch, are placed with Hall element in notch, coiling are wound on the magnet of notch two sides, suddenly
You are connected at element with coiling, and according to electromagnetic induction principle, current value and the current value on original lead exported in coiling is positively correlated.
The current value on original lead can be measured by such manner.
But existing coiling is directly to be wound on magnet, due to the presence of notch, so that coiling takes off from magnet
From influencing to test.Therefore, it is necessary to the gap positions in magnet, and a fixed device is arranged for the prior art, so that coiling is opposite
It is fixed, it is unlikely to fall off.
Utility model content
The utility model provides a kind of current sensor skeleton and current sensor, can fix coiling, make current sense
The overall structure of device is more compact, firm.
The utility model provides a kind of current sensor skeleton, including two fixed plates disposed in parallel and connection two
The attachment base of fixed plate, the attachment base is interior to be equipped with the arc-shaped channel to match with magnet, and the channel extends simultaneously to two sides
Through the fixed plate, the channel for magnet for passing through；Coiling is wound on the attachment base, the fixed plate is equipped with
The card slot passed through for coiling.
Preferably, the attachment base is set as matching with magnet arc-shaped.
Preferably, where the attachment base is in fixed plate in altitude range.
Preferably, the upper surface of fixed plate is arranged in the card slot, and the attachment base is formed to the arc-shaped of lower recess.
Preferably, the channel forms horn mouth in fixed plate surface.
The utility model also provides a kind of current sensor, including above-mentioned current sensor skeleton.
In the utility model, skeleton includes the attachment base of two fixed plates of two fixed plates disposed in parallel and connection,
Arc-shaped channel is equipped in attachment base, skeleton can be socketed in magnet gap position, and coiling can be then wound on skeleton, Hall
Sensor can be set in channel.Skeleton in this way fixes the structure members such as coiling and Hall element, prevents coiling
It slides, keeps overall structure more compact and firm.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of current sensor of the prior art.
Fig. 2 is a kind of structural schematic diagram of the current sensor skeleton of embodiment of the utility model.
Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.
The utility model embodiment provides a kind of current sensor skeleton, as shown in Figure 2 comprising two disposed in parallel
Fixed plate 1 and the attachment base 2 for connecting two fixed plates 1, the attachment base 2 is interior to be equipped with the arc-shaped channel to match with magnet
20, the channel 20 extends through the fixed plate 1 to two sides, channel 20 be set as matching with magnet it is arc-shaped, then
Magnet passes through the fixed plate 1 and attachment base 2 at both ends.The gap position of magnet may be provided in the channel 20 of attachment base 2, around
Line is then wound on the attachment base 2, and Hall element needs to be located at the gap position of magnet, then Hall element can be fixed on connection
In the channel of seat 2.Meanwhile the fixed plate 1 is equipped with the card slot 11 passed through for coiling.Coiling can be laid out by card slot 11,
To export induced field current, used for external circuit.
In one embodiment, the attachment base 2 is set as matching with magnet arc-shaped.Attachment base 2 is located at as circle
Arc compared to straight panel structure, can extend the length of attachment base 2, correspondence can increase coiling and exist so that attachment base 2 is supplied
The circle number of coiling on attachment base 2 promotes the detection accuracy of sensor to increase output electric current.
In one embodiment, the attachment base 2 is in 1 place altitude range of fixed plate, i.e. the height of attachment base 2
It is not above the height of fixed plate 1 upper surface and lower end surface.It is in entire skeleton within the scope of fixed plate 1, it can be reasonable
Control the volume of skeleton.
In one embodiment, the upper surface of fixed plate 1 is arranged in the card slot 11, and the attachment base 2 is formed to recessed
Sunken is arc-shaped.
In one embodiment, the channel 20 forms horn mouth 20 on 1 surface of fixed plate, is inserted into channel convenient for magnet
In 20.
The utility model also provides a kind of current sensor, including above-mentioned current sensor skeleton.
The above content is combine specific embodiment further detailed description of the utility model, and it cannot be said that
The specific implementation of the utility model is only limited to these instructions.For the utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made.
