Description

Technical Field

[0001] The utility model relates to the technical field of current sensors, in particular to a current sensor which is convenient for fixed installation. Background Art

[0002] A current sensor is a sensor device for detecting current, which includes a magnetic core, which is provided with at least one gap, and in which a Hall element is arranged. The Hall element can be used to measure the magnetic field strength in the gap between two opposite end faces of the magnetic core. Since the strength of the magnetic field depends on the magnitude of the current flowing through the conductive element, the output signal of the Hall element represents the magnitude of the current flowing through the conductive element. The most common way to install the existing current sensor is to fix it with a number of bolts. Although the bolt fixation is stable enough, it is time-consuming and laborious to install or remove the current sensor. When it is necessary to detect different directions, it is necessary to remove a number of bolts, adjust the installation direction of the current sensor, and then reinstall it, which will waste a lot of time in actual use. Frequently turning the bolts many times will cause damage to the threads on the bolts, and will also affect the detection efficiency.

[0003] Based on this, a current sensor that is easy to install is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

A second reset spring 25 is fixedly arranged between the upper end of the guide slider 23 and one side of the inner side of the mounting column 21. When in use, when the current sensor body 11 needs to be installed on the upper end of the mounting base plate 15, the pull rod can be pulled 24, the pull rod 24 drives the guide slider 23 to slide. When the guide slider 23 slides, under the action of the T-shaped slider, one end of the limit slider 22 moves to the inside of the mounting column 21, and the mounting column 21 is inserted into the mounting hole at the upper end of the mounting base plate 15. Then the pull rod 24 is released, and under the action of the second reset spring 25, the guide slider 23 returns to the initial position.

The push rod 18 drives the limit card plate 17 to disengage from the limit column 16, and then the current sensor body 11 is rotated. The user uses the indicator plate 20 in conjunction with the scale value to quickly determine the adjustment angle of the current sensor body 11. After the adjustment is completed, the push rod 18 is loosened, and the push rod 18 returns to the initial position under the action of the first reset spring 19. Each limit bar on the inner side of the limit card plate 17 is between the two limit bars on the limit column 16, so that the limit column 16 is fixed, thereby limiting and fixing the current sensor body 11.
