Claims

[Claims for Utility Model Registration] (1) A detecting coil, a bobbin for winding the detecting coil, a magnetic core passing through the center of the bobbin, and a case housing these, including one end of the magnetic core. protrudes from the case to form a detection head, and the other end of the magnetic core is provided with a bias magnet and a spacer for increasing magnetic flux, and a lead wire extends from the detection coil via a terminal. In the pulse generator, an anchor protrusion with a relatively small radius is integrally molded on the bobbin to hold the winding end of the coil, and a burr is formed on the end surface of the anchor protrusion by thermal caulking. A pulse generator characterized by: (2) A detection coil, a bobbin for winding the detection coil, a magnetic core passing through the center of the bobbin, and a case for housing these, with one end of the magnetic core protruding from the case to accommodate the detection head. , and a bias magnet and a spacer for increasing magnetic flux are provided at the other end of the magnetic core, and a lead wire extends from the detection coil through the terminal, wherein the terminal is connected to the terminal. At least one overhang is provided in the binding portion for binding the ends of the detection coil, so that the binding of the detection coil is divided into two parts with the overhang as a border. A pulse generator characterized by: (3) Furthermore, the binding part of the terminal has a reinforcing rib, so that when the binding part is folded down to give slack to the extra wire of the coil terminal after soldering, the binding part is folded with the overhang part as a boundary. The pulse generator according to claim 2, wherein the pulse generator is characterized in that the curved portion is not bent.
