を形成する。尚、このコンタクト形成用部材１はその下
方が一体となるよう接続され複数個が連結された状態で
製造される。First, from a flat plate having spring properties such as phosphor bronze, press punching is performed to form two parallel protruding pieces 2 extending upward and a protruding piece 3 extending downward, as shown in figure (a), and a joint between them. 4, and the contact forming member 1 is provided with locking protrusions 5 on both sides of the coupling portion 4 for use when inserting an insulator.
form. Incidentally, this contact forming member 1 is manufactured in a state in which a plurality of members are connected so that the lower part thereof is integrally connected.

成する。Next, the contact forming member 1 is automatically conveyed to another press machine, and press bending is performed so that the connecting portion 4 is bent so that the two protruding pieces 2 extending upward are facing each other, as shown in FIG.
The contact 11 is bent inward by about 90 degrees, and bent into a substantially inverted U shape so that the outer surface of the protruding piece 2 becomes the contact surface 2a.
このとき接触面２ａの接触点は所定間隔離れるよう加工
する。At this time, the contact points on the contact surface 2a are processed to be separated by a predetermined distance.
このようなコンタクト１１にフープメッキを施す。前述
したように接触点は離れているためメッキはコンタクト
１１全体に施すことができる゛。Hoop plating is applied to such contacts 11. As mentioned above, since the contact points are far apart, plating can be applied to the entire contact 11.
次に（ｃ）図のように挿入口付近の幅１２は広く、その
奥がコンタクト１１の幅７！３より狭い幅ｌｌ。Next, as shown in the figure (c), the width 12 near the insertion opening is wide, and the width ll at the back is narrower than the width 7!3 of the contact 11.

ることになる。The contact 11 is inserted into the insertion hole 8 of the insulator 7 having the stepped portion 9 so that the contact 11 is inserted. The contact 11 passes through the insertion hole 8 at the width I12 portion without contacting the inner wall thereof, and the contact 11 passes through the step portion 9.
When the contact 11 reaches this point, the protruding pieces 2 of the contacts 11 come into contact with the inner wall, and in a portion of the width IlI, the protruding pieces 2 of the contacts 11 are deformed inward due to their own spring properties, and the contact surfaces 2a come into contact with each other.

A cross-sectional view between ' is shown in Figure (e). (e) When looking at the cross section as shown in the figure, the insertion hole 8 of the insulator 7 is slightly wider near the insertion opening, and the locking protrusion 5 of the contact 11 is press-fitted into that area. The contact 11 is fixed to the insulator 7 by press-fitting the locking protrusion 5 and contacting the inner wall of the insertion hole 8 of the protruding piece 2.
本実施例ではコンタクト１１の突出片２は内側にカール
させその外面を接触面２ａとしたが、外側にカールさせ
、内面を接触面とするコンタクトでも本発明を適用でき
ることは明らかである。In this embodiment, the protruding piece 2 of the contact 11 is curled inward and its outer surface is used as the contact surface 2a, but it is clear that the present invention can also be applied to a contact that is curled outward and has its inner surface used as the contact surface.

形等の不都合も生じない。According to the present invention, the plating process can be performed after all the press work for forming the contact is completed, which simplifies the manufacturing process, and the contact surface of the contact is in a non-contact state before inserting the insulator. Therefore, problems such as contact deformation do not occur.
