れ、長期間使用しても、大気中の腐食ガスにより腐食さ
れて、接触不良となることはない。(B) Since the cable or device and the connection side are in close contact with the socket or plug integrally by insert molding, the contact part of the connector terminal is completely shielded from the outside air, and even if it is used for a long period of time, it remains in the atmosphere. It will not be corroded by the corrosive gas inside, resulting in poor contact.
(c) 基体、シールパッキンその他各部材は、一体成
形されるので、きわめて小型とすることができる。(C) Since the base body, the seal packing and other members are integrally molded, the size can be made extremely small.
(d) 多芯コネクタにおける各芯線の接続部は、独立
して気密性が保たれるので、冠水等で個々接触部の気密
性(水密性)の破壊に対して、電気的な線間短絡事故を
生じるおそれは小さい。(D) Since the connecting portion of each core wire in the multi-core connector is independently kept airtight, an electrical short circuit between wires is caused against destruction of airtightness (watertightness) of each contact portion due to flooding or the like. The risk of an accident is low.

ネクタ。1. An outward flange is continuously provided in a direction orthogonal to an axis of a bottomed tubular portion having a front opening, and a wiring connecting portion is continuously provided at a rear side of the bottomed tubular portion, and Inside the bottomed tubular part, a plurality of pins that are parallel to the axis are fixed by insert molding, and the front end surface and the inner and outer surfaces of the bottomed tubular part of the base body made of hard synthetic resin are integrally molded from soft synthetic resin. By covering with a seal packing, the socket has a fitting hole in which the tip of each pin is circularly surrounded by a seal packing inside the bottomed tubular part, and the front part is It is a cylindrical holding tube that can be fitted into the fitting holes that individually surround each pin of the socket without slack, and this holding tube has jacks corresponding to each pin of the socket, and at the rear part of each jack. The front part of the cable connected to the rear end The plug is embedded in a base made of synthetic resin, and has a front end face orthogonal to the axis and an enlarged step portion that expands in the radial direction is formed behind the holding cylinder. At this time, the dimensions of each part are determined so that the front surface of the enlarged stepped portion at the front end of the plug is in pressure contact with the front end surface of the holding cylinder of the socket, and further, on the side surface of the bottomed cylindrical portion of the base body of the socket, By forming a pair of left and right cut grooves that are parallel to the axis from the front end, a flexible piece that faces the front is formed between the two cut grooves, and an inward projection and a plug are provided at the front end of the flexible piece. An airtight multicore connector is provided on the outer surface of the holding cylinder with which the inward projection abuts, the engaging concave hole with which the inward projection can engage when the front surface of the enlarged step portion of the plug and the front end surface of the socket are pressed against each other. .
