えるべき接続ピン4の本数と配置に合せた貫通孔11が
形成されている。The insulating plates 3 are made by molding thin plates such as hard fiber-reinforced plastic to match the shape of the inner circumferential surface of the cylindrical metal fitting 2. Two insulating plates 3 are attached to each other, and the connecting pins 4 to be provided in the receptacle 1 are inserted through each plate. Through-holes 11 are formed in accordance with the number and arrangement of the through-holes.
接合ピン4は取付は部となる中央部に抜は止め用のr4
12を備えている。The joining pin 4 has a r4 hole in the center to prevent it from being pulled out.
It is equipped with 12.
このレセプタクル1はつぎのように組立てられる。This receptacle 1 is assembled as follows.
2枚の絶縁板3に接続ピン4を、絶縁板3の貫通孔11
に挿通すると共に、その鍔12を2枚の絶縁板3で挟み

着する。絶縁板3は筒形金具の底部を構成する。Connect the connecting pin 4 to the two insulating plates 3, and insert the through hole 11 in the insulating plate 3.
At the same time, the collar 12 was fixed by being sandwiched between two insulating plates 3, and both insulating plates 3 were inserted into the cylindrical metal fitting 2 from the base side, and the insulating plate 3 was brought into contact with the fixing ring 6. For installation, a stop ring 13 elastically biased to expand outward is fitted into the groove 10, and the two insulating plates 3 are sandwiched between the fixing ring 6 and the stop ring 13. The insulating plate 3 constitutes the bottom of the cylindrical metal fitting.

る。Note that this receptacle 1 is installed by inserting the base of the cylindrical metal fitting 2 into a hole 15 provided in the casing 14 of the device, and
Screw 1 with waterproof tight material 16 interposed on the back side of lunge 8.
7 to be attached to the casing 14.

より密封する。In the receptacle 1 having such a configuration, the cylindrical metal fitting 2
Since the three insulating plates, the insulating plate 3, and the four connecting pins are only held together by contact, there are minute gaps. The present invention seals this gap by the following means.

続ピン4の周辺から筒形金具2の内周面にわたり3〜5
mm程度の厚さに充填する。Place the receptacle 1 with the opening side (the side into which the plug 5 is inserted) facing upward, and apply powder or particulate synthetic resin 18 (up to about 1.5 mmφ) from the opening side to the connecting pin 4 as shown in FIG. 3 to 5 from the periphery to the inner peripheral surface of the cylindrical metal fitting 2
Fill it to a thickness of about mm.

3を損傷する程の高温が必要なものは使用できない。Both thermoplastic and thermosetting synthetic resins can be used; however, with thermal nJtlj resins, it is necessary to pay attention to the melting temperature, and with thermosetting resins, the range of heating temperatures that can be adopted is limited. It is necessary to pay attention to the liquidity of For example, in receptacle 1 for connecting to a control unit built into a servo motor that consumes a large amount of power, the surrounding moisture level is 1.
20''c, so a material with a melting temperature higher than that must be selected, and materials that require a high temperature to melt that would damage the insulating plate 3 cannot be used.

な電機絶縁性を示し、ざらに耐熱性、耐油・耐薬品性を
備えており、好適である。In the examples, polyamide is used. Polyamide has a relatively high molding shrinkage rate of 0.6 to 2%, but its melting point is 213 to 265"C, and its viscosity when melted is low, making it easy to spread into the gaps. It is suitable because it shows good electrical insulation properties and has rough heat resistance, oil resistance, and chemical resistance.

が、溶融樹脂にある程度の圧力を加えて間隙に樹脂を押
込むことができる。The filled synthetic resin 18 heats the receptacle 1 to 300°C.
It is melted by placing it in an open air atmosphere for about 10 minutes, or by using a hot saw inserted through the opening of the cylindrical metal fitting 2, or by hot air from a blower (Fig. 2). Using a hot iron requires a special shape that will not damage the connecting pin, but it is possible to press the resin into the gap by applying a certain amount of pressure to the molten resin.
このように形成されたレセプタクル1は各間隙が溶融後
硬化した樹脂によりシールされ、筒形金具2の開口部か

路が完全に遮断される。In the receptacle 1 thus formed, each gap is sealed with a resin that has been melted and hardened, and the passage of water or other liquid from the opening of the cylindrical fitting 2 through the base to the inside of the device is completely blocked.
また、合成樹脂は一般に電気絶縁性が高く、溶融後硬化
