ABSTRACT:
A contact block includes a contact having a pair of contact pieces spaced apart, and an electrically insulating combining block for combining the contact pieces. Each contact piece is provided with a horizontal U-shaped or a horizontal V-shaped intermediate region having a folded end portion and a pair of arm portions vertically spaced apart from the folded end portion; a first tip region extending downward from the tip portion of one of the arm portions; and a second tip region extending upward from the tip portion of the other arm portion. The folded end portions of both contact pieces are buried within the combining block and the remaining parts of both contact pieces are projected from the combining block. Thereby, in a state of being assembled into the electrical connecting apparatus, adjoining contacts are positioned by the combining block, and contacts can be exchanged by exchanging contact blocks.
