A terminal 1 (a perspective view of which is shown in FIG. 4) used in an electrical device as shown in FIG. The surface roughness of the end face 4c is very important in order to allow current to flow. Therefore, conventionally, the processing method shown in FIG. 5 has been adopted in the manufacturing process of the terminal 1. That is, after drilling the hole 1a in the terminal 1, the burring portion 4a is processed. At that time, burrs and cracks 4b are generated, so after that, the end face 4c of the burring part 4a of the terminal 1 is scraped with the cutter 5, and then chamfered 4d is performed with the cutter 6, and the threaded part 4e is processed with the tap 7. In some cases, the flat part 4f
Connector 2 may also be connected to.
従来の端子の製造は以上のような方法で加工を
行つているので、次のような問題点があつた。
Conventional terminals have been manufactured using the method described above, which has resulted in the following problems.
(a) 端子のバーリング端面を刃物による削り加工
するので、加工時間がかかり、生産性がよくな
い。(a) The burring end face of the terminal is shaved with a knife, which takes time and reduces productivity.
(b) 端子のバーリング端面を刃物による削り加工
するので、端面の面粗度がよくない。(b) Since the burring end face of the terminal is shaved with a knife, the surface roughness of the end face is not good.
(c) 削り加工を行うので肉が少なくなり、接触面
が少なくねじ強度がよくない。(c) Scraping is performed, so there is less meat, and the contact surface is small, resulting in poor thread strength.
(d) バーリング加工のみではバーリングの出た反
対側の接触面が少ない。(d) If only burring is used, the contact surface on the opposite side of the burring is small.

In the method of this invention, the end face of the burring of the terminal is formed by plastic working, chamfering is also performed at the same time if necessary, and the opposite side where the burring is exposed is also plastically deformed to increase the contact surface. It is something.

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, after drilling a pilot hole 1a for burring in the terminal 1, a burring portion 4a is formed.
At that time, burrs and cracks 4b occur and the surface roughness is poor, so in the next step, a forming jig as shown in Fig. 2 is used, and between the pedestal 9 and the forming blade 8 provided with the pilot part 8a, The terminal 1 is inserted, and the end face 4c, flat part 4f, and chamfer 4d of the burring of the terminal 1 are processed by plastic deformation. Thereafter, the tap 7 is used to process the threaded portion 4e. Note that the chamfer 4d is provided to avoid bulging during tapping. In the above example, the end surface 4c is processed after the burring 4a is formed, but the end surface 4c and the chamfer 4d may be processed simultaneously when the burring 4a is formed. Also, after forming the burring 4a, the end face 4c and the chamfer 4d
may be processed in two steps, and at this time, the chamfer 4d may be processed using the cutter 6.
〔発明の効果〕
以上の説明から明らかなように、この発明によ
れば次のような効果がある。[Effects of the Invention] As is clear from the above explanation, the present invention has the following effects.
(a) バーリングの端面を切削加工から塑性加工に
変更したので、生産性がよくなり、加工費が安
価になつた。(a) By changing the end face of the burring from cutting to plastic working, productivity has improved and processing costs have been reduced.
(b) 従来は切削部を捨てていたが、本発明の方法
では捨てないので、肉が有効に利用でき、接触
面積が多くとれ、品質の高いものが得られる。(b) Conventionally, the cut portion was discarded, but in the method of the present invention, it is not discarded, so the meat can be used effectively, the contact area is large, and high quality products can be obtained.
(c) 塑性加工のため硬度が上がり、ねじ強度が強
くなる。(c) Due to plastic working, the hardness increases and the screw strength increases.
(d) 塑性加工でバーリングの端面を形成するた
め、接触面の面粗度もよくなる。(d) Since the end face of the burring is formed by plastic working, the surface roughness of the contact surface is also improved.
