Description
Technical Field
[0001] This application relates to the field of current sensor technology, and more specifically to a current sensor mounting device. Background Technology
[0002] A current sensor is a component used in industrial power supply equipment to detect the magnitude of current. The current sensor has a through-hole that passes through a current-carrying conductor to measure the current. When the rated current of the current sensor is large, its size also increases, taking up considerable space inside the industrial power supply. Since the current sensor itself does not have mounting holes, when detecting the current on a current-carrying conductor outside the industrial power supply, the current sensor is directly fitted onto the conductor. The current sensor and the conductor can move relative to each other, making it impossible to fix the current sensor permanently to the conductor.
[0003] In related technologies, two clamps are fixed to the current-carrying conductor and clamped on both sides of the current sensor to fix the current sensor to the current-carrying conductor. However, as the volume of the current-carrying conductor and the current sensor increases, the volume of the clamps also needs to increase, which increases the cost. Utility Model Content

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] A current sensor is a component used in industrial power supply equipment to detect the magnitude of current. The current sensor has a through-hole that passes through a current-carrying conductor to measure the current. When the rated current of the current sensor is large, its size also increases, taking up considerable space inside the industrial power supply. Since the current sensor itself does not have mounting holes, when detecting the current on a current-carrying conductor outside the industrial power supply, the current sensor is directly fitted onto the conductor. The current sensor and the conductor can move relative to each other, making it impossible to fix the current sensor permanently to the conductor.
[0030] In related technologies, two clamps are fixed to a current-carrying conductor and sandwiched between two sides of the current sensor to fix the current sensor to the current-carrying conductor. However, as the volume of the current-carrying conductor and the current sensor increases, the volume of the clamps also needs to increase, increasing costs.
