PURPOSE: To increase joining force of connection terminals through tensile force between a fitting pawl and a fitting part, in which an opening angle of fitting pawls of contact members in an tube-shaped contactor assemble is made acute, and an acute opening angle is also formed between each fitting part of a cable connection terminal and an electrode-member connection part to be fitted with the fitting pawls. CONSTITUTION: A fitting part 22 of a corresponding connection part 20 or a fitting part 40 of each corresponding contact terminal is fitted to each opposite face 26A of fitting pawls 26 provided on both sides of each contact member 28 in a contact assemble 24. The fitting face 26A is formed in a way that an acute angle (θ) is made between an elongated line (A) from the face 26A and an elongated axial line (B) of the contact member 28. Each fitting pawl 26 has an acute opening angle (θ) facing opposite to each other. Each fitting face 22A of a nail part 22 in the connection part 20 to be fitted with the fitting face 26A and each fitting face 40A of the connection terminal fitting parts 40 are so formed that an opening angle between an axial line and each fitting face 22A or 40A is made equal to the acute angle (θ) in accordance with the fitting face 26A. When tensile force of power cables in a longitudinal direction is increased, the fitting pawl 26 and the fitting parts 22 and 40 grasp alternately the power cable to increase the joining force thereof.
