Over-current protection apparatus

Abstract

This invention provides one over flow protector to make direct current pass to detect its current values, wherein, the protector comprises the following parts: at least one iron core, one main coil and one Hall parts; the said core side has one protruding part extending along iron; the said main coil is covered on protruding part; when direct current passes, the protruding part forms relative one magnetic pass intensity relative to the Hall part to receive magnetic intensity formed by main coil.

Description

technical field

[0001] The invention relates to an overcurrent protector, in particular to an overcurrent protector which can measure the current value without direct contact with the circuit. Background technique

[0002] In recent years, high-tech technology has advanced by leaps and bounds, especially in the field of microelectronics-related technology and process. Therefore, electronic-related products have penetrated into every family and all walks of life and become an indispensable part of modern life. Of course, human needs are increasing. In order to enable electronic devices to achieve more functions, the electronic products are moving towards the goal of diversified functions. However, under the consideration of safety, electronic products must detect the voltage and current load or supply and output in the circuit to ensure that the damage or damage of electronic products to human beings or peripheral equipment to human beings is minimized.

Embodiment Construction

[0019] Please refer to FIG. 4 , which is a schematic diagram of the structure and actuating circuit of a commonly used Hall element. The Hall element 4 has a sensor 41 , and the sensor 41 is a sheet structure constructed by extending in an X direction and a Y direction. When an operating voltage Vin is applied, the inductor 41 is activated to induce a magnetic flux density (along the Z direction) flowing through the current, and the inductor 41 responds to an output voltage Vout. Since the magnetic flux density is directly proportional to the flowing current, the Hall element 4 does not need to be in contact with the circuit (connected in series) when measuring the current value.

[0020] Please refer to FIG. 5 , which is a three-dimensional structural diagram of a preferred embodiment of the overcurrent protector of the present invention. The overcurrent protector 5 of the present invention allows a DC power supply I to pass through, and detects a current value of the DC pow...
