Abstract
An electromagnetic induction type ABS sensor frame comprises a frame injection molding body and electrode sheets cast inside the frame injection molding body. The electrode sheets are parallel to the central axis of the frame injection molding body. The two end parts of each electrode sheet are exposed out of the frame injection molding body. The frame injection molding body is of a tubular structure, and a first magnetic core, a steel magnet and a second magnetic core are sequentially embedded inside the frame injection molding body. The two ends of the steel magnet respectively abut against the first magnetic core and the second magnetic core. The other end of the first magnetic core is exposed out of the frame injection molding body. The outer wall of the frame injection molding body is provided with annular arc current limiting bodies which are fixed between the end parts, exposed out of the frame injection molding body, of the two ends of the electrode sheets. According to the electromagnetic induction type ABS sensor frame, the two annular arc current limiting bodies are arranged on the surface of the frame injection molding body, thereby effectively reducing the impact force of plastic particle fluid on a coil during injection molding, avoiding the situation in which the welding point of the coil is broken due to too large instant pressure, and ensuring the qualified rate of finished sensors.
