接続してある。 The present invention will be described below with reference to embodiments shown in the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a housing of a distributor fixed to an internal combustion engine, and is made of a resin material having electrical insulation properties.
A distributor shaft 2 driven by an internal combustion engine is rotatably held. 3 is a centrifugal governor attached to the distributor shaft 2,
A cam cylinder 4 is rotatably attached to the distributor shaft 2, and is advanced by a centrifugal governor 3 by a position corresponding to the engine speed. A breaker plate 5 is rotatably attached to the housing 1 and is driven by a vacuum advance device (not shown) to a position corresponding to the negative pressure in the intake pipe of the internal combustion engine. 6
A breaker is an ignition-related device fixed on the breaker plate 5 and opens and closes at every predetermined rotation angle of the cam 4a provided on the cam cylinder 4 as the cam 4a rotates. Reference numeral 7 denotes an insulated rotor that is removably fitted and fixed to the tip of the cam cylinder 4, and a power distribution core 8 made of a conductive material such as iron is embedded and fixed in the upper surface of the insulated rotor. A connector portion 9 is integrally formed on a part of the outer periphery of the housing 1, and includes one ends 10a, 11a of plate-shaped electrical connection wires 10, 11 insert-molded within the housing 1. Connector part 9
is provided in a position where it does not get in the way when the housing 1 is attached to an internal combustion engine (not shown). A hole 9a is provided in a part of the peripheral wall of the connector portion 9 for fitting with a mating connector 20, and the engaging claw 20a of the mating connector 20 is fitted with a spring force. The other ends 10b, 11b of the electrical connections 10, 11 are connected to the breaker 6. Further, 12 is a cap made of an insulator fixed to the open end of the housing 1 with a screw 13, and 14 is a center electrode that receives the ignition voltage. It is electrically connected to the power distribution core 8. 17 is cap 12
This is a high-voltage terminal fitting that is insert-molded into the engine, and is connected to an ignition plug provided in the internal combustion engine via a cord (not shown).

定される。 In the above configuration, the distributor shaft 2 rotates in synchronization with the rotation of the internal combustion engine, and as the distributor shaft 2 rotates, the cam 4a rotates via the centrifugal governor 3, and the cam 4a rotates. Accordingly, the breaker 6 is turned on and off and an ignition signal is generated. This ignition signal is transmitted from one end 10b, 11b to the other end 10a, 10b via electrical connection wires 10, 11, and is transmitted from the fitted connector 20 to an external transformer. By insert-molding the electrical wiring inside the electrically insulating resin housing 1 in this way, the conventional rubber grommet used to prevent water from seeping into the interior becomes completely unnecessary.
Further, the shape of the connector on the side of the housing 1 is such that a small window 9a is formed since the housing material is made of polyphenylene sulfide, which is highly rigid among resin materials, and cannot be imparted with spring properties. The mating connector 20 has an engaging claw 2 in this small window 9a.
0a is caught and fixed by the spring back.
本発明によれば、電気配線のシールドがハウジ
ングにて代用され部品点数削減、組付け工数省力
することができるという優れた効果がある。 According to the present invention, the shield of the electrical wiring is replaced by the housing, and there is an excellent effect that the number of parts and the number of assembly steps can be reduced.
