Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、例えば車両用充電制御装置のアース端子のよ
うに、樹脂によりモールド成形して用いるターミナルの
接触面の形状に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the shape of a contact surface of a terminal used by molding with a resin, such as a ground terminal of a vehicle charging control device.
従来、電気装置のターミナルを例えば車両用充電制御装
置のアース端子として用いる場合には、充電制御装置の
ケース型の治具にターミナルを配置し、この型に樹脂を
流し込むといったモールド成形により、ターミナルの接
触面のみが充電制御装置の樹脂製ケースの外部に露出す
るようにしている。そして、車両用発電機のフレームと
接触させアームをとっている。Conventionally, when a terminal of an electric device is used as a ground terminal of a vehicle charging control device, for example, the terminal is arranged in a jig of a case mold of the charging control device, and resin is poured into the mold to mold the terminal. Only the contact surface is exposed to the outside of the resin case of the charge control device. The arm is provided in contact with the frame of the vehicle generator.
また、電気装置のターミナルは、他の金属部材との接触
時に接触面圧が低いと、接触抵抗が大きくなっていた。
従って、この接触抵抗を小さくするためには、接触面圧
を高くすれば良く、ターミナルの接触側の面全面に多数
の凸部を設け、この凸部が他の電気装置の接触面と接す
るようにして接触面積を小さくすることが考えられる。Further, the contact resistance of the terminal of the electric device is large when the contact surface pressure is low at the time of contact with another metal member.
Therefore, in order to reduce the contact resistance, it is sufficient to increase the contact surface pressure, and a large number of convex portions are provided on the entire contact side surface of the terminal so that the convex portions contact the contact surface of another electric device. It is conceivable to reduce the contact area.
〔発明が解決しようとする課題〕 ところが、上述の接触側の面全面に多数の凸部を設けた
ターミナルの接触側の面の外縁部を上記ケース型の治具
に押しつけることにより、この接触側の面と、樹脂が流

記治具とが接し、上記凸に対する凹部と上記治具との間
には隙間が生じる。[Problems to be Solved by the Invention] However, by pressing the outer edge portion of the contact-side surface of the terminal provided with a large number of convex portions on the entire contact-side surface to the case-type jig, When the surface of the terminal is made to be separated from the portion that becomes the resin inflowing case, at the outer edge of the contact side surface of the terminal, the convex portion and the jig are in contact, and the concave portion and the jig with respect to the convex portion are There is a gap between them.
そして、樹脂をケース型に流し込み、モールド成形する
際に、樹脂がターミナル接触側の面の外縁部から、上記
凹部と上記治具との間の隙間を通り、ターミナル接触側
の面の内側へと流れ込んでしまい、樹脂が接触面より高
く盛り上がり、接触不良になる可能性がある。Then, when the resin is poured into the case mold and molded, the resin passes from the outer edge of the terminal contact side surface to the inside of the terminal contact side surface through the gap between the recess and the jig. There is a possibility that the resin will flow into the resin and rise above the contact surface, resulting in poor contact.
そこで、本考案においては、接触側の面に凹凸部を備
え、かつ樹脂によりモールド成形しても接触不良になる
ことのないターミナルを提供することを目的とする。Therefore, it is an object of the present invention to provide a terminal which is provided with a concavo-convex portion on the contact side surface and which does not cause contact failure even when molded with resin.
上記目的を達成するために本考案では、樹脂によりモー

に用いる治具を密着させ、多数の凸部への樹脂の付着を
阻止する平面部を備えることを特徴とする電気装置のタ
ーミナルを提供するものである。To achieve the above object, in the present invention, in a terminal which is molded by resin and the contact side surface is exposed to the outside of the resin and contacts the metal member, a large number of protrusions are formed inside the contact side surface of the terminal. The multiple protrusions come into contact with the metal member, and a jig used for molding at the time of molding is closely attached to the entire outer periphery of the contact side surface of the terminal so that the multiple protrusions The present invention provides a terminal for an electric device, which is provided with a flat portion for preventing the resin from adhering.
上記のように、ターミナルの接触側の外縁に備えた平面

の面に樹脂が流れ込むことがなくなる。As described above, the flat portion provided on the outer edge of the contact side of the terminal and the jig are in close contact with each other, so that the resin does not flow into the contact side surface of the terminal.
以上述べたように本考案においては、モールド成形する

う優れた効果がある。As described above, in the present invention, when molding is performed, the resin does not flow into the contact side surface, and contact failure occurs even in a terminal that is used by molding and exposing the contact side surface to the outside of the resin. It is possible to increase the contact surface pressure without breaking and to prevent the resin from flowing in by crushing the convex parts and closely contacting the terminals to the molding jig, so the life of the molding jig is not reduced. There is an excellent effect.
