Description

Hall sensor convenient for cementing Technical Field The utility model belongs to the technical field of sensors, and relates to a Hall sensor convenient for glue binding. Background With the expansion of population and city construction scale, the electric equipment of the modern society is more and more, the power consumption is also more and more, the corresponding city power supply equipment is often overloaded, the power supply environment is worse and worse, and the problem is more and more serious. When the current power state is tested in real time and the damage such as overcurrent and overvoltage occurs, the sensing detection, sensing sampling, sensing protection and the like become the current power application development trend, so that the real-time detection of the power supply environment through the Hall sensor is also generated; the step of gluing the sensor means that the internal circuit part of the sensor is subjected to glue filling and packaging treatment in the production process of the sensor, so that the sensor pouring sealant is needed; However, the hall sensor has an interface on the outer side thereof, so that a connecting wire harness between the circuit board and the interface is easy to fall into pouring sealant when the glue pouring packaging is carried out on the inner side of the hall sensor, the interface and the wire harness are polluted, and the problem is troublesome in the production and assembly process of the sensor. Patent document CN109917163a discloses a hall current sensor, which comprises a shell, be equipped with annular installation department and circuit board in the casing, be equipped with annular iron core on the annular installation department, annular iron core outer coil just is equipped with a breach, be equipped with hall element in the breach, hall element, coil all are connected with the circuit board electricity, the circuit board draws forth the casing with the wiring through a row of needle, still be equipped with cooling device in the casing, cooling device includes the semiconductor refrigeration piece, the cooling ring, temperature sensor, treater and power regulator, the semiconductor refrigeration piece glues through heat conduction silicone grease with the cooling ring, temperature sensor, power regulator, the semiconductor refrigeration piece all is connected with the treater electricity, the treater still is connected with the circuit board electricity. Patent document CN201145706Y proposes a hall current sensor including an annular insulating housing, an annular core having a gap, an annular device provided in the insulating housing and having an annular inner wall surrounding the annular inner wall of the insulating housing, a circuit board provided in the gap of the annular core and having a detection circuit, the circuit board being electrically connected to the hall device, and a shield ring provided in the insulating housing, the shield ring being provided inside the annular inner wall of the annular core and surrounding the annular inner wall of the insulating housing.
