特公昭53−18713 号に示すように、圧着ガイド部に端子
を圧着するタイプであった。2. Description of the Related Art The conventional connection between a lead frame and an electric wire is
As shown in Japanese Examined Patent Publication No. 53-18713, it was a type in which terminals were crimped to the crimping guide.

【発明が解決しようとする課題】従来構造は圧着治具を
使用するため圧着部の周囲に圧着治具にぶつかるものが
有る場合は採用できない。つまり接続部がケース内に有
るような場合は前記従来構造は圧着治具がケースにぶつ
かるため圧着できない問題を有していた。Since the conventional structure uses a crimping jig, it cannot be used when there is something that hits the crimping jig around the crimping portion. That is, when the connection portion is inside the case, the conventional structure has a problem that the crimping jig hits the case and cannot be crimped.
【０００４】本発明の目的は、リードフレームと電線と
をケース内で接続することができる接続構造を提供する
ことにある。An object of the present invention is to provide a connection structure capable of connecting a lead frame and an electric wire within a case.

It is achieved by melting and joining the lead frame and the electric wire.

でリードフレームをケース中へ配置出来る。According to the first solution, laser welding can be performed by further providing a hole in the lead frame and providing a projection on the connection terminal or by forming the connection terminal into a shape that can be clipped on the lead frame. Since laser welding is possible, it is possible to weld even if there is a gap between the welding base material and the welding jig, so the lead frame can be placed in the case. In the second solution, since soldering is performed by infrared rays or laser, the lead frame can be placed in the case because the joining can be performed even if there is a gap between the joining base material and the jig.
