However, the connector used in this case has a complicated terminal shape, which makes it difficult to reduce the cost of the connector. However, how to configure the connector at a low cost is a big problem.
[0003]
[Prior art]
Hereinafter, the case where the target connector is a plug connector will be described as an example.

[0014]
Furthermore, the third lead 211b_-3  The plug contact position is the second plug terminal 211._-2The fourth lead 211b is bent substantially in an L shape because it is separated from the lead position of the fourth lead 211b._-Four  The plug contact position is the third plug terminal 211._-3Since it is away from the lead position, it is simply bent into an L shape.
[0015]
In the connector 21 in this case, the first to fourth plug terminals 211 are used._-1~ 211_-FourIn a normal means such as forming the connector 11 by press-fitting the connector into the insulator 212 from the plug contact side, for example, the first plug terminal 211_-1And the second plug terminal 211_-2And lead 211b when press-fitting_-1, 211b_-2  Since the connection terminal 211c interferes with each other, the configuration as a connector is difficult.
