Description

Technical Field

[0001] The utility model relates to the technical field of Hall current sensors, in particular to a self-locking open Hall current sensor. Background Art

[0002] The Hall current sensor is an electrical quantity detection device developed based on the Hall effect principle for isolating and detecting the primary current. The magnetic field generated by the primary current is gathered in the magnetic ring, and the magnetic field is detected at the air gap by the Hall element. The output of the Hall element is amplified so that the output of the sensor can accurately reflect the size and changes of the primary current.

[0003] For example, a self-locking open type Hall current sensor with the authorization announcement number "CN2201051431U" solves the problem that the existing self-locking open type Hall current sensor is inconvenient to use tools under limited space, which reduces the efficiency of installation. The above-mentioned buckle at the end pops out from the upper shell. The utility model uses the spring and the buckle in coordination. When the lower end of the rotating lock plate is pressed, the buckle and the upper shell are loosened, and the upper shell is rotated to open. When the sensor is to be closed, it is only necessary to close the upper shell with the main shell through the rotating shaft. The upper shell and the main shell are automatically locked together through the buckle mechanism. The existing self-locking open type Hall current sensor requires the coordination between the spring and the buckle to lock the upper shell into which the buckle enters. Considering that there is a certain slack between the spring and the buckle connection, after the upper shell and the main shell are buckled together, the buckle pops out from the upper shell, resulting in instability in the self-locking. Utility Model Content

[0006] Preferably, the outer wall of the mounting plate is provided with a locking mechanism, and the locking mechanism includes a push handle and a locking plate, the outer wall of the push handle is rotatably connected to the mounting plate, the lower end of the locking plate is fixedly connected to the mounting plate, the outer wall of the push handle is fixedly connected to the round rod, the outer wall of the round rod is rotatably connected to the circular locking rod, the inner wall of the push handle is provided with a card slot, the inner wall of the card slot is movably connected to the locking plate, the outer wall of the locking plate is fixedly connected to the card strip, and the outer wall of the card strip is tightly pressed against the push handle.

[0007] Preferably, the outer wall of the circular locking rod is tightly pressed against the locking hook, and the outer wall of the locking hook is fixedly connected to the main housing.

[0010] Preferably, the outer wall of the upper shell cover is fixedly connected to the connecting block, and the outer wall of the connecting block is tightly abutted against the main shell body.

[0011] The utility model proposes a self-locking opening type Hall current sensor, which has the beneficial effect that: the position of the mounting plate on the mounting frame is changed by adjusting the position of the adjusting plate by the threaded rods at the upper and lower ends of the mounting frame, and the locking plate is inserted into the locking plate through the card slot on the push handle.
