この発明は、端子を合成樹脂製ベースにインサート成形
する端子ベースの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a method for manufacturing a terminal base in which a terminal is insert-molded into a synthetic resin base.
［従来技術とその問題点コ
従来、金属製端子は金型のキャビティ内に固定した状態
で、溶融樹脂を射出し、端子を樹脂製ベースにインサー
ト成形していた。[Prior art and its problems] Conventionally, metal terminals were fixed in a mold cavity, then molten resin was injected and the terminals were insert-molded into a resin base.
しかし、このような従来の端子ベースの製造方法によれ

た端子の曲げ、切断加工等によって、端子とベースとの
接合面に微少な隙間が生じていた。However, according to such conventional terminal base manufacturing methods, minute gaps may be created at the bonding surface between the terminal and the base due to differences in thermal shrinkage between the metal and resin, bending of the inserted terminal, cutting process, etc. after molding. was occurring.
そのため、端子の半田付は時に発生するフラックスなど
の腐食性溶剤が上記の隙間からベースの内側に浸入して
、接点機構に付着し、接点の腐食や接触抵抗の増加など
を招く欠点があった。また、製品の洗浄時に、その洗浄
液が製品の内部に浸入するなどの欠点があった。Therefore, when soldering terminals, corrosive solvents such as flux that are sometimes generated enter the inside of the base through the above-mentioned gaps and adhere to the contact mechanism, resulting in corrosion of the contacts and an increase in contact resistance. . Further, there is a drawback that when cleaning the product, the cleaning liquid infiltrates into the interior of the product.
そこで、上記インサート成形前に、上記端子のインサー

しかしながら、上記端子のインサート部に金属と樹脂と
のぬれ性を高める材料を塗布するのみでは、上記隙間を
確実に封止することは不十分であることが確認された。Therefore, an attempt has been made to coat the insert portion of the terminal with a material that enhances the wettability between metal and resin before the insert molding. (Refer to Japanese Patent Application No. 60-166372.) However, simply applying a material that enhances the wettability of metal and resin to the insert portion of the terminal is insufficient to reliably seal the gap. confirmed.
［発明の目的］
この発明は上記欠点を解決するためになされたもので、

的する。[Object of the invention] This invention was made to solve the above-mentioned drawbacks,
It is an object of the present invention to provide a method for manufacturing a terminal base that can further improve the sealing performance between the terminal and the synthetic resin base.

することを特徴とする。[Configuration and Effects of the Invention] The method for manufacturing a terminal base according to the present invention includes forming an uneven portion on an insert portion of a terminal before insert molding, and then
The method is characterized in that a material that enhances the wettability between metal and resin is applied to the uneven portions.

に、接点の腐食等の不良品の発生が防止できる。According to the present invention, after forming an uneven portion on the insert portion of the terminal, a material that improves the wettability of metal and resin is applied to the uneven portion, thereby further improving the sealing performance between the terminal and the base. This makes it possible to effectively prevent the infiltration of solvents such as solder flux and cleaning fluids, as well as to prevent the occurrence of defective products such as corrosion of contacts.
［実施例の説明］ 以下、この発明の実施例を図面にしたがって説明する。[Explanation of Examples] Embodiments of the present invention will be described below with reference to the drawings.

着性を向上させる。FIG. 1 shows an example of a terminal base for explaining the manufacturing method according to the present invention, in which 1 is a flat metal terminal, and its insert part IA has a V as shown in FIG.
By forming an uneven part 3 consisting of a letter-shaped groove and applying a silane-based, titanium-based, or chromium-based coupling agent, that is, a material that improves wettability, to the outer surface of the uneven part 3 by dipping means or the like, the above-mentioned The surface of the terminal l is modified to improve its adhesion to the resin.

スが得られる。After that, by molding the synthetic resin base 2 with the terminal 1 fixed and held in a predetermined position in the mold cavity, the insert part IA has excellent sealing properties and ensures that solder flux, cleaning liquid, etc. do not infiltrate. This provides a terminal base that can prevent this from occurring.
上記端子１の凹凸部３は、第３図および第４図で示すよ

。In this way, after forming the uneven portion 3 on the insert portion IA of the terminal 1, the sealing property between the terminal 1 and the base 2 is improved by applying a material that improves the wettability of metal and resin to the uneven portion 3. Further, it is possible to effectively prevent the infiltration of solvents such as solder flux and cleaning liquids, and also to prevent the occurrence of defective products such as corrosion of contacts.
