©0 to the position where the handle part PY hits the surface of the device .001 and to solve this problem; Both front surfaces of the TY pivoting portions are worked flat in the preferred form; The release arm 91 is then shaped to a shape and size such that the axial parts FY are prevented from coming into contact with the terminal plate 1 when the electric wire 0 is connected and the release arm 01 rotates in the direction Reverse direction of operation by spring force of the locking parts ;. As a result; It is undesirable in earlier configurations with “FA” supporting parts that the movement of the release lever, Fe, is not impeded by contact with terminal plate 11 and that the completeness of the electrical wire connection is not shown with certainty. Furthermore it"; In that preferred form, as shown in Figure 9; The 0 isolating rib 110a protrudes from the center of the bearing 011 toward the front portions of it. As shown in Fig. 11, the YY pivoting portions of the two release arms 01 provided in tandem on the 100 are separated from each other by a YY buffer so that the Ve release arms can be prevented from rotating. simple by overlapping or not rotating at all.
