Hoop material a is press-molded and continuously mass-produced.
is removed and press-formed to form a pin material B, and then the material b is bent and press-formed to form a pin material C.
This is cut from the hoop material a to make a plug pin A. The plug pin A has a pin 7 and a locking piece 8 formed on a small cylindrical part 6, and the lower end of the small cylindrical part 6 is opened. Part 9
A caulking piece 11 is provided on a U-shaped portion 10 extending downward from the opening 9.

る。 Then, the corded pin A with the lower end of the plug pin A caulked and the tip of the cord 3 connected is inserted into the pin insertion hole 2 of the insulating base 1, and the shoulder part 12 of the plug pin A is inserted into the pin insertion hole. At the same time as colliding with the entrance of the small diameter part 13 of 2, the step part 1
By locking the locking piece 8 to 4, the locking piece 8 can be inserted and fixed in a one-touch state to prevent it from coming off.
(ii) ところが、上記従来構成のプラグピンＡは、

極プラグを生じるという大きな問題があつた。 Therefore, when the plastic cover 5 is molded onto the plug body provided as described above, the molding material that is injected under strong pressure enters the inside of the pin from the opening 9, and the molding material enters the pin at the joint. As it protrudes from the pin 15 and solidifies as it is, a lump that protrudes and solidifies is formed at the tip and side of the pin 7, as well as in the gap between the pin 7 and the small diameter portion 13. However, there was a big problem of producing defective multi-pole plugs.

In a plug pin A having an opening 9 at the lower end and a caulking piece 11 protruding from a U-shaped part 10 continuing below the opening 9, the opening 9 at the lower end of the small cylindrical part 6 is located at the side edge of the opening 9. Small pieces 1 that are folded inward and overlapped with each other
6, 16, and the small pieces 16,
Reference numeral 16 denotes a plug pin of a round multi-pole plug, which extends integrally from the side edge of the opening 9.
It is A′. (See Figures 1 and 2) In the above, the small pieces 16, 16 become the opening 9 of the small cylindrical part 6 when the pin material b is pulled out and press-formed in the process of press-forming a plug pin from the hoop material a. The pin material b is cut to form approximately triangular small pieces 16, 16 on the extended part (leaving a part that would otherwise be removed), and the pin material b is bent into a small cylindrical part 6 and a U-shaped part 10. During molding, the small pieces 16, 16 are simultaneously folded inward at right angles so as to overlap each other, thereby closing the opening 9.

大の効果を発揮し得る。...Functions and Effects (i) As described above, the plug pin A' has its opening 9 closed with the small pieces 16, 16, so the plug pin A' has a cord attached to the U-shaped portion 10 as described above. After the corded plug pins, which are caulked with the caulking pieces 11 at the ends of the corded plug pins, are inserted and fixed into the respective pin insertion holes 2 of the insulating base 1, when molding the plastic cover 5 (i.e., downward press molding). The molten molding material injected under strong pressure is injected into the small piece 16 of the opening 9. , 16, and is stopped at the small cylindrical portion 6 without penetrating into the inside of the small cylindrical portion 6. Therefore, the molding material does not penetrate into the small cylindrical portion 6, and is stopped at this portion. It does not stick out from gaps and solidify, and therefore, it can exhibit a great effect that can completely eliminate the conventional problems caused by this.
(ii) また、射入された成形材料が押圧力となつて
開口部９を閉塞した小片１６，１６を押圧する
ので、プラグピンA′が前方へ押され、その肩
部１２が小径部１３入口に強く圧着することゝ
なるので、これによつて、ピン７と小径部１３
の隙間から成形材料が食み出す恐れを除去し得
る。(ii) In addition, the injected molding material acts as a pressing force and presses the small pieces 16, 16 that closed the opening 9, so the plug pin A' is pushed forward and its shoulder 12 becomes the entrance of the small diameter part 13. As a result, the pin 7 and the small diameter portion 13 are tightly crimped.
It is possible to eliminate the fear that the molding material will protrude from the gap.
また、小片１６，１６は互に重ね合わせるよ
うに折り曲げ成形されているので、成形材料の
強圧によつても、内方へ曲つて開口してしまう
ような恐れは全くない。 Moreover, since the small pieces 16, 16 are bent and molded so as to overlap each other, there is no fear that they will bend inward and open even under the strong pressure of the molding material.
(iii) 前項の如く、プラグピンA′が前方へ押圧さ

に嵌挿していないことによるピンの抜け外れ不
良を無くし得る秀れた利点もある。(iii) As mentioned in the previous section, by pressing the plug pin A' forward, the insertion action of the plug pin A' into the pin insertion hole 2 is performed more reliably, and its dimensions By performing accurate fitting and insertion, the locking piece 8 provided at the fixed position of the pin is reliably locked with the stepped portion 14 provided at the fixed position of the pin insertion hole 2. Therefore, it is possible to completely insert and fix the plug pin without coming off, and there is also an excellent advantage that it is possible to eliminate the problem of the pin coming off and coming off due to the conventional plug pin not being accurately inserted into the pin insertion hole.
