In this terminal part, the insulating sheet 2 is peeled off to expose a plurality of foil-shaped conductors 3.
A metal terminal plate 4 having a spring property is joined to the exposed portions 3a of the conductors 3 by ultrasonic welding. The first
Although only one metal terminal plate 4 is shown in the figure, the metal terminal plate 4 is actually bonded on all exposed portions 3a. These metal terminal plates 4 are made of rectangular conductive metal plates,
A spring portion 4a, which is cut and raised from a metal plate and curved in an arc shape and whose rear end is a free end, is provided at the center thereof. In addition, a folded-back portion 4b is formed at the tip of the metal terminal plate 4, and the folded-back portion 4b projects forward and is folded back to act as a locking portion for the connector housing.

Engage as shown to ensure locking to the housing 6. Since this locking is required only on both sides of the flat cable 1, the folded portion 4b does not have to be provided on the metal plate 4 arranged in the middle. Further, the spring portion 4a can be stably connected to the connection terminal in the housing 6 by utilizing its elastic force. When the terminal portion is removed from the housing 6, the locking portion 6a may be moved by using a lock releasing means to release the locking with the folded portion 4b of the metal terminal plate 4 and then pulled out.
