でも接触不良が生じ易くなる等の欠点がある。[Detailed explanation of the invention] Since the conventional fitting of the metal tip to the lower insulating collar of this type of small female plug is simply the fitting of the cylindrical tip to the circular hole of the core collar, slips inevitably occur on both sides. In addition, there is a risk of loose rotation of the cylindrical tip and the circular hole collar, which may cause poor contact with the insertion head. However, there are drawbacks such as a slight misalignment due to slight insertion play or wear of the insertion head due to long-term use, etc., which tends to cause poor contact.

案実施の一例を図面に付て説明すると次のようで
ある。 The present invention eliminates the above-mentioned drawbacks of the conventional method, and allows the fitting of the lower insulating collar and the metal chip to the metal chip by changing the shape of the body part of the chip to the collar into an appropriate rectangular tube shape such as a triangle. At the same time, the fitting hole of the collar is also made into a square hole, a protrusion is cut and raised on the square tube part, and a small window hole is bored in the collar to lock the protrusion, The protrusion locking ensures a secure fit between the tip and collar, eliminating any loose rotation due to slipping between the two, and ensuring reliable contact with the insertion head even during long-term use. The purpose is to provide an economical product with outstanding performance, and an example of the implementation of the present invention will be explained below with reference to the drawings.

A required number of cut and raised protrusions 4 and 5 (single or plural (three in the figure)) are formed on the upper and lower parts of the flat surface of the rectangular tube part 3, with the protrusions 4 on the upper side facing upward. The protruding piece 5 on the lower side is notched to open upwardly and inwardly, and has a fitting hole 6 for the insertion head at the bottom, and a fitting hole 6 for the square tube part 3 of the tip 1 to fit therein. The fitting hole in the circumference of the lower insulating collar 7 to be inserted is spaced apart from the rectangular tube part 3 by a margin of 8.
A corresponding number of small window holes 1 are formed in the circumferential body portion corresponding to the protruding pieces 4 on the upper side of the chip 1 to be fitted into the chip.
0 in the square hole 9 of the lower insulating collar 7.
The square tube part 3 of the chip 1 is loosely fitted into the chip 1, and the upper protrusion 4 is locked in the small window hole 10.
is fixedly fitted on the collar 7, and a metal cylinder 11 that is shorter than the tip 1 is fitted on the outside of the circumference of the collar 5. The cylindrical part 2 is fitted and protruded to a required length, and the upper insulating collar 14 with the donut disc part 13 of the lug terminal 12 fitted on the back side of the flange edge is fitted, and the cylindrical part 2 protrudes above the chip 1. It is constructed by crushing the portion 2 into a flat terminal portion 15.

る。 Since the present invention is constructed as described above, when the fitting part of one square tube part 3 of the metal chip 1 is inserted into the square hole 9 of the circumferential body part of the lower insulating collar 7, the chip 1 will open the upper part. The square hole 9 of the lower insulating collar 7 has a hole shape into which the square tube portion 3 is loosely fitted, leaving a margin of 8 in the cylindrical portion 2. As a result, the square tube part 3 of the chip 1
The fitting portion is loosely inserted into the collar 7. However, since the fitting body of the chip 1 is a rectangular cylinder with a triangular shape, etc., and it is fitted into the same-shaped hole of the collar, unlike the conventional fitting between cylinders and circular holes, In addition to the fact that the slip does not rotate, the rectangular tube portion 3 of the chip 1
A required number of raised protrusions 4 and 5 are formed in the upper and lower parts of the flat surface of the fitting body, and the upper protrusions 4 are outwardly opened upward.
On the other hand, a corresponding number of small window holes 10 for locking the protruding pieces 4 are provided at locations corresponding to the protruding pieces 4 on the upper side of the tip 1 on the circumferential body of the collar 7. If the tip 3 is inserted into the square hole 9 of the collar 7 so that the cut-and-raised protrusion 4 that opens outward is engaged with the small window hole 10, the lower end of the tip 1 will be placed on the inner bottom surface of the collar 7. When hit, the upper protruding piece 4 reaches the small window hole 10 and locks against the upper edge of the window due to the spring opening, and due to the locking by this cut and raised piece, the tip 1 The fitting body part is fixedly fitted to the collar 7 without any play and rotation as described above.

り小型雌プラグが組立てられる。 Then, with respect to the metal chip 1 and the lower insulating collar 7 that are fixedly fitted, the lower part of the metal cylinder 11 is fitted on the outside of the circumferential body of the collar 7, and the lower part of the metal cylinder 11 is fitted between the metal chip 1 and the lower insulating collar 7. The upper cylindrical part 2 is fitted and protruded to a required length, the upper insulating collar 14 with the lug terminal 12 fitted is fitted, and the cylindrical part 2 of the chip 1 is crushed into a flat terminal part 15. As a result, a small female plug is assembled.

角筒部３は前記の如く下側絶縁カラー７に対する
遊び回動なき嵌挿を保障すると共に、上方の円筒
部２は平板状の端子部１５の圧潰加工に適切であ
る。 As a result of transforming a part of the metal chip 1 into a rectangular cylinder part 3 such as a triangular shape and transforming the upper part into a cylinder part 2,
As described above, the square cylindrical portion 3 ensures fitting into the lower insulating collar 7 without play and rotation, and the upper cylindrical portion 2 is suitable for crushing the flat terminal portion 15.

係止並びに角筒と角孔との嵌合関係により、確実
な遊び回動なき固定嵌着が、該チツプ１の単なる
嵌込み作業だけで実に簡単に得られる。 The fitting of the metal chip 1 to the lower insulating collar 7 of the plug assembled as described above involves the locking of the collar 7 to the small window hole 10 by the cut-and-raised piece on the upper side, and the fitting of the square tube and the square hole. Due to the mating relationship, a secure and fixed fit without play and rotation can be achieved quite simply by simply inserting the chip 1.

くなる。 Furthermore, by forming a required number of upwardly opening cut-and-raised protrusions 5 in the lower trunk of the protrusion 4 on the upper side of the chip 1, the inner-opened cut-and-raised protrusions 5 This is because, as a result of the tip 1 being elastically protruded into the body of the tip 1, the lower protruding piece 5 acts as a spring contact piece and comes into elastic pressure contact with the insertion head. In combination with the fixed fitting between the chip 1 and the lower insulating collar 7, contact failures are reliably eliminated.

経済的な製品が提供できる等の効果がある。 Furthermore, by making the square hole 9 of the lower insulating collar 7 with respect to the square tube part 3 of the chip 1 so that there is a slight clearance 8, the plane part of the square tube part 3 is different from that of a conventional cylinder. Unlike this, the lower protrusion 5 cushions slightly outward due to the pressure contact force of the lower protrusion 5 against the insertion head, so the cushioning action of the flat part has a margin for the insertion and removal of the insertion head. As a result, the pressing force of the lower protrusion 5 against the insertion head is moderately relaxed due to the above-mentioned cushioning action, so that the insertion and removal operations of the insertion head are not stiff. , it becomes really smooth and good. As a result, electrical conductivity is high, there is no contact failure, and safety is outstanding and no defective products occur.
0, the chip 1 is cut and raised in two stages, upper and lower, and the protrusions 4 and 5 are notched, and a part of the chip 1 is processed into a rectangular tube, so it is easy to manufacture and has a simple mechanism. , assembly work is simple and efficient,
This has the effect of being able to provide economical products.
