る。According to the invention of claim 3, the joint portion of claim 1 is provided with a pilot hole for positioning the terminal plate during insert molding of the terminal plate. Therefore, in addition to the effect of claim 1, the conductive plate is provided. The terminal hole can be accurately positioned by using the pilot hole of the joint during insert molding, and the contact position accuracy can be improved, and by installing the pilot hole in the joint, it is installed at each contact point of the terminal plate. Since the number of pilot holes that had been used can be halved, the work of inserting the mold becomes easier, and the pilot holes at the joint are then divided and removed together with the joint, so the number of pilot holes after assembly is reduced, and therefore the number of pilot holes after assembly is reduced. The adhesion between the terminal plate and the molded product (housing) can be further improved.

It is easy to secure the contact position, and it is possible to prevent deterioration of the contact position accuracy during transportation. Further, according to the invention of claim 5, since the concave portion is formed on the inner surface of the housing corresponding to the back surface of the joint portion according to claim 1, in addition to the effect of the first embodiment, a recess on the inner surface of the housing is formed when the joint portion is divided. The split mold can be easily positioned by using, and when, for example, the housing is formed of a primary molded body and a secondary molded body, the secondary molded body (resin) enters the concave portion during the secondary molding of the housing. Adhesion between the molded article and the secondary molded plate is improved, and peel strength can be increased. Therefore, the strength of the housing can be improved.
