  • Patent number: 6551119
    Abstract: There are provided blocks (A), (B), . . . corresponding to pieces of sub-harness (A), (B), . . . . In each block, there are provided a longitudinal opening 14 and a bottom opening 16, which are arranged in the vertical direction, at a forward end portion of each accommodating chamber 11 for accommodating the spring contact point 23a of the connecting terminal 20(A), 20(B), . . . . When the blocks are put on each other in the vertical direction, the top 23a of the spring contact point 23 on the lower block 10(A) side gets into the bottom opening of the upper block 10(B) from the longitudinal opening 14. Therefore, the top 23a of the spring contact point 23 on the lower block 10(A) side comes into contact with the rear face of the base piece 23b of the spring contact point 23 on the upper block so that electrical continuity can be attained. Due to the foregoing, the splice between the pieces of subharness (A) and (B) can be absorbed.
