部分を使用せずに済むことにある。In the above-mentioned prior art, since the armature and the rectifier are connected by one terminal for each phase, it is necessary to melt the solder and remove the caulking during the maintenance work. Further, when reassembling, the same terminal must be used for caulking and soldering work, which causes a problem of deterioration of connection reliability due to deterioration of the terminal. The purpose of the present invention is to
At least in the first maintenance work, the crimping and soldering work does not need to use the pre-crimped and soldered part of the terminal.

This will be described with reference to FIG. According to this embodiment, the rotor 4 is pressed into the shaft 5 and moves as a rotor. Rotor 4
A field coil 6 is arranged inside the. Further, a stator 8 having an armature coil 7 is concentrically arranged on the outer circumference of the rotor 4. Here, the stator 8 is held by being sandwiched between a front bracket 9 and a rear bracket 10, and the rotor 4 is held by a ball bearing 11 incorporated in the front bracket and a ball bearing 12 incorporated in the bracket 10. .. The electric power generated in the magnetic circuit composed of the rotor 4, the field coil 6, the stator 8 and the armature coil 7 is applied to the rectifier 1 fixed to one surface of the rear bracket 10 through the lead wire 2 extending from the armature coil 7. Of the terminal 3, only the portion 3a on the side opposite to the stator is used and caulked and soldered (see FIG. 1). At that time, the stator side 3b portion of the terminal 3 retains the shape of the lead wire 2 before caulking. The rectifier 1 supplies the obtained electric power to the cooling fin 13 as an output current.

照）。In the above vehicle alternator, when performing maintenance on the market, the lead wire 2 and the terminal 3 are disconnected by cutting the 3c portion of the terminal 3, and the lead wire 2 and the terminal 3 are again connected. When connecting, caulking and soldering is performed using the portion 3b (see FIG. 2).

性が低下してしまう。In this structure, the first disassembling work of the connecting portion between the lead wire 2 and the terminal 3 is completed only by cutting, and the work can be simplified. Further, since the second connecting work between the lead wire 2 and the terminal 3 is performed by using 3b for the first time, the initial reliability of the terminal 3 can be maintained. In the case of the terminal 3 having no structure 3b, the first disassembling work of the connection portion involves the work of melting the solder and the work of removing the caulking, which deteriorates the maintainability of the market. In addition, the connection work between the lead wire 2 and the terminal 3 for the second time needs to reuse the portion 3a deteriorated by soldering and caulking, so that the connection reliability decreases.

Further, since the second connecting work between the lead wire 2 and the terminal 3 is performed by using a new part of the terminal 3, the connection reliability can be secured as in the first connecting work.
