In the above-mentioned prior art, the terminal d and the joint terminal h are connected by butting each other, so if the terminal d is not completely inserted and locked in the terminal accommodation chamber b, the joint terminal h When inserted, it falls off from the housing, creating a non-conducting area, but it is difficult to confirm this condition from the outside at a glance. Even if the terminal d is initially completely inserted, a similar problem may occur due to damage to the locking member. Additionally, there is a risk of forgetting to insert the joint terminal and closing the lid during assembly, but this cannot be noticed just by looking from the outside.

ら、挿入作業は１回で済む。Effects of the Invention As explained above, according to the present invention, the terminal can be engaged with the contact of the joint terminal by inserting the contact of the joint terminal from the same direction as the terminal, in addition to the known locking means in the terminal accommodation chamber. A matching locking member can be provided, thereby doubly preventing extraction. Furthermore, incomplete insertion of the terminal can be resolved by inserting the joint terminal, and since the presence or absence of insertion of the joint terminal can be easily confirmed from the outside, it is possible to prevent the conventional case of forgetting to attach the joint terminal. Furthermore, even if there are a plurality of joint terminals, they can be integrated into one by using an insulating cap, so that the insertion work only needs to be done once.
