「産業上の利用分野」
本発明は、電線等に取着して電気導通に使用する端子の
製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for manufacturing a terminal that is attached to an electric wire or the like and used for electrical continuity.
「従来の技術」
端子は電気接点部の性能向上のために、金属板表面にメ
ッキを施すのが通常であり、大別して以下の二様の方法
によってメッキ処理された端子が成形されている。``Prior Art'' In order to improve the performance of electrical contact parts, terminals are usually plated on the surface of a metal plate, and plated terminals are formed using the following two methods.
即ち、その一つは、予めメッキ処理された板材を、プレ

ッキを施す後メッキ方法がある。Specifically, one of them is a pre-plating method in which a plate material that has been plated in advance is pressed and formed into a terminal of a desired shape;
Another method is a post-plating method in which a plate material that is not plated is press-worked to form a terminal in a desired shape, and then the formed terminal is plated.
「発明が解決しようとする課題」
しかし１以上の従来の成形方法の前者の先メッキ方法は
、例えば第３図示の圧接端子１の場合。``Problems to be Solved by the Invention'' However, the former pre-plating method of one or more conventional molding methods is, for example, in the case of the pressure contact terminal 1 shown in FIG.

を生じ易い等の不具合がある。Since the blade surface 11 of the pressure welding blade 8 of the U-shaped slot, which is the point of contact with the electric wire conductor, comes into contact with the fractured surface during press punching, a plating condition exists. In addition, in the latter post-plating method, the conical contact portion 9 that fits with the mating female terminal is made of a flat plate material.
Since the terminal is formed by 80° close bending, the plating liquid penetrates into the inside of the close contact by capillary action, and the plating liquid that adheres to the inside causes deterioration of the terminal over time. Since the terminals are plated, it is difficult to make the plating thickness uniform, and furthermore, there are problems such as deformation of the terminal shape.
本発明は、以上の従来手段の難点を解消する端子の製造
方法を提供するものである。The present invention provides a method for manufacturing a terminal that overcomes the drawbacks of the conventional means described above.

理し。"Means for Solving the Problems" The molding method of the present invention that solves the above technical problems is as follows: "In molding a plated terminal of a desired shape, a flat hoop material is progressively fed to form a "pressing hole". A flat plate-shaped primary processed hoop material is formed by punching out at least [the fractured surface contact area where the punched fractured surface forms an electrical contact after terminal forming], and the roll-shaped primary processed hoop material is progressively fed and subjected to plating treatment. death.

メッキ液の無用な浸透付着現象が解消される。"Function" According to the manufacturing method of the present invention described above, at least the "broken surface contact area where the punched broken surface forms an electrical contact after forming the terminal" is plated on a previously punched flat plate-shaped primary hoop material. This eliminates the presence of plating at the fracture surface contact area and the unnecessary penetration and adhesion of the plating solution.

る。Since the plating process is carried out by progressively feeding the primary processed hoop material of the rolled flat plate, the plating film thickness is uniform and there is no risk of deformation. This enables efficient progressive feeding by utilizing the "press feed holes" formed in advance during the primary processing.

First, referring to FIG. 1 showing an example applied to the molding of a press-contact terminal 1, a flat hoop material 6 as a molding base material is progressively fed to form a press-forming feed hole 4 and a punched fracture surface after molding. The fracture surface contact area 5 which becomes the blade surface 11 of the U-shaped slot pressure contact blade 8 and becomes an electrical contact is punched out, and the primary processed hoop material 3 of the flat plate is formed by leaving the other punched area 7 indicated by the dotted line in the figure. . Then, this primary processed hoop material 3 is made into a roll of flat material again, and is fed progressively to the plating layer for plating treatment, and then progressively fed to the secondary nibless using the feed hole 4, and the remaining material is The other punched parts 7 are punched and bent.
