The invention discloses an openable magnetic core for a current sensor. The magnetic core comprises a semi-annular upper shell, a semi-annular lower shell, a semi-annular upper magnetic core and a semi-annular lower magnetic core; the joints of the upper magnetic core and the lower magnetic core are connected through a connecting mechanism; the connecting mechanism comprises a fixed block; fixed clamping plates on the two sides of the arc-shaped groove are clamped at the two sides of the joints of the upper magnetic core and the lower magnetic core; arc-shaped clamping plates are connected tothe lower end of the upper shell and the upper end of the lower shell, and the magnetic core body composed of the upper magnetic core and the lower magnetic core is clamped and fixed through the upperarc-shaped clamping plate and the lower arc-shaped clamping plate; an upper inserting plate inserted into a rectangular opening is arranged at the lower end of the upper shell, and a lower insertingplate inserted into the rectangular opening is arranged at the upper end of the lower shell. According to the invention, the overall structure of the upper shell, the lower shell, the connecting mechanism and the magnetic core body is firm and stable, so the deviation between the upper magnetic core and the lower magnetic core of the magnetic core body after combined installation is avoided, and the combined installation structure of the upper magnetic core and the lower magnetic core is firm.
Description
technical field [0001] The invention belongs to the technical field of magnetic cores, and in particular relates to a magnetic core for an openable and closable current sensor and a manufacturing method thereof. Background technique [0002] The current sensor is a detection device that can sense the information of the measured current, and can transform the information sensed by the detection into an electrical signal that meets certain standards or other required forms of information output according to certain rules. It consists of a closed magnetic core and a winding coil. [0003] The magnetic core of the existing current sensor is generally divided into two types, one is integrated, and the other is split type. Among them, the open-close magnetic core is composed of upper and lower semicircular magnetic cores. The structural stability of the combined installation is poor. The two semicircular magnetic cores are prone to displacement deviation and the structure is unst...
