Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness device for a generator, and more particularly to a technique for connecting a wire harness for a generator installed inside a crankcase and a main harness for a load installed outside the crankcase. The present invention relates to a wire harness device effectively used for a magnet generator mounted on a motorcycle such as a motorcycle.

[0002]

2. Description of the Related Art Generally, a two-wheeled vehicle such as a motorcycle uses a magnet generator, which is installed in a crankcase of an engine. On the other hand, loads such as batteries and various lamps are naturally installed outside the crankcase. Therefore, it is necessary to pull out the wire harness of the magneto generator to the outside of the crankcase and electrically connect it to the main harness connected to the load.

As a conventional wire harness device for a magnet generator of this type, a wire harness for a magnet generator is inserted into a rubber grommet fitted to a side wall of a crankcase, pulled out of the crankcase, and then pulled out. Some harnesses are configured to be electrically connected to a main harness, routed around a vehicle body frame, and connected to a load at a predetermined location.

[0004]

However, the wire harness device for a magnet generator as described above has the following problems. The wire harness of the magneto-generator has a long total length, and various types of standard products are required for the total length depending on the vehicle type.

Even if the specifications of the coil of the magnet generator are the same, each time the specification of the vehicle body frame is changed, the wire harness also becomes a different type, so that the magnet generator is affected by the specification change of the vehicle body frame. Becomes irrational,
In addition, production management becomes complicated, and as a result, the productivity of the motorcycle as a whole decreases.

Since the wire harness of the magnet generator is long, it is difficult to handle the magnet generator in the production line of the magnet generator, the packing work, the assembly line to the engine, etc., and the productivity is reduced.

When the temperature inside the crankcase is high, it is necessary to manufacture the entire wire harness including the outside of the crankcase with heat-resistant specifications, which increases the cost of the magnet generator and the wire harness.

An object of the present invention is to solve the above-mentioned problems and to provide a wire harness device for a generator having good productivity as a whole.

Even if the specifications of parts other than the engine such as the vehicle body are changed, if the specifications of the engine are the same, it is possible to use the same specifications of the magnet generator, so the number of models of the magnet generator will increase. Can be reduced.

Since the length of the wire harness on the magnet generator side can be shortened, not only the handleability of the magnet generator as a whole is improved, but also the soldering process of the wire harness and the stator coil is automatically soldered. It can be carried out automatically by an application processing device.

When the temperature inside the crankcase is high, it is only necessary to increase the grade related to heat resistance performance only for the magneto-generator side wire harness inside the crankcase, so the heat resistance performance grade for the load side main harness outside the crankcase You can avoid ups.
