Traditionally, when using cords to connect electrical devices, a connecting plug has been attached to the end of the cord to facilitate the combination of various electrical devices. Among the connector plugs with attached connectors, female connector plugs are constructed with a built-in blade holder, so they are generally used in the 1980s.
As seen in Publication No. 162579 and Publication No. 136170 of 1983, a blade holder attached to the tip of the lead wire is incorporated into a pre-molded connector housing.
If necessary, screws or the like were used to secure the blade holder and housing.

Recently, as mentioned above, corded connection plugs have come to be used for connection to electrical equipment, and there have been many demands for quality, electrical safety, and cost reduction of corded connection plugs. For this reason, corded connection plugs have come to be molded integrally onto the tip of the cord using synthetic resin molding machines, but female connection plugs have a built-in receiving blade and are easy to attach to equipment. When the protruding blade of an outlet or male connector plug is inserted into the blade fitting, the blade must be perfectly connected to the blade fitting, so elasticity is added to the fitting. Therefore, when molding a connecting plug with synthetic resin, there is no molding method that would allow molten synthetic resin to flow into the joint with the blade or cause the joint to lose the necessary elasticity. Therefore, female connector plugs must be pre-molded from synthetic resin as mentioned above. It is usually assembled using a housing made of

When molding a corded female connection plug with a built-in blade holder using synthetic resin, the present invention accommodates and fixes the blade holder that has been attached to the ends of multiple lead wires in advance. This problem was solved by assembling using a fixture that prevents molten synthetic resin from flowing into the contact area with the blade, and then molding the outer shell with synthetic resin using a molding machine.
The fixing device includes a main body having a plurality of blade holder housing chambers each having a blade holder insertion opening on one side and a connection port for the blade holder of an outlet or a mating plug on the other side, and a blade holder accommodating chamber. On the side of the blade holder insertion opening of the chamber, there is a fitting part for the lid that closes all the blade holder housing chambers at the same time, and the inner wall of the fitting part has a groove that matches the flat plate part of the blade holder and the cross-sectional shape. A gap is formed between the cover plate and the flat plate part of the blade holder fitting into which the flat plate part of the blade holder is inserted.Protrusions for locking the cover body are provided on the inner wall, and the cover body is connected to the main body via a hinge. This problem can be solved by using a blade holder made of a thermoplastic synthetic resin that has a higher melting point than the external molding synthetic resin.

Made of synthetic resin such as ABS, Diyuracon, polycarbonate, methacrylic, and nylon, with blade holder insertion hole 3 on one side.
On the opposite side, a plurality of blade holder housing chambers 2 each having an inner diameter smaller than the outer diameter of the blade holder 8 and having a connection port 4 with a blade holder such as an outlet or a mating connection plug are arranged at appropriate intervals. The main body 1 formed in this manner has blade holder insertion holes 3, 3, 3,
A fitting part 6 of the lid 5 which simultaneously closes the... side is provided, and a groove having a depth approximately equal to the cross-sectional shape of the flat plate part of the blade holder 8 is provided on the inner wall of the fitting part 6.
When the blade holder is fitted into the fitting part 6, a gap is created into which the flat plate part of the blade holder fits, and when the cover 5 is fitted into the fitting part 6 of the main body 1, the cover 5 does not fall off. A locking protrusion 7 is provided on the side wall of the fitting portion 6 of the main body 1 to prevent this from happening, and the lid 5 is connected to the main body 1 via a hinge 10 and integrally molded. That is, the blade holder 8 is fixed by providing a flat plate between the blade holder part of the blade holder and the connecting part of the lead wire, and fixing the blade holder between the lid 5 of the fixture and the blade holder housing chamber 2 of the main body 1. It is clamped and fixed by the inner wall of the fitting part 6 of the lid body provided on the receiving metal insertion opening 3 side.

As described above, since the present invention is constructed, when manufacturing the female connector plug 11 with a cord as shown in FIG. After assembling the receiving bracket 8 and fixing it in the mold frame of the molding machine using the connection port 4, etc., it is sufficient to mold an outer shell with synthetic resin to enclose the fixture and the lead wire, and the lead wire is attached to the fixture. When assembling the bracket 8, the lid 5 is connected to the main body 1 via a hinge, so it can be assembled more easily than when the lid 5 is molded separately, and the outer shell is made of synthetic resin. Even when molded to enclose the fixture, the blade holder insertion opening side 3 of the blade holder housing chamber 2 of the fixture is completely closed by the lid body 5, so there is no fear of molten plastic flowing in, ensuring electrical safety. Furthermore, since the lead wire and the connection part of the holder are wrapped and fixed in the outer synthetic resin, there is no risk of the lead wire breaking, falling off, or coming into contact with the connection part of the adjacent holder. It has advantages such as good insulation properties.
