Then, two wires W are inserted into the holes 1422 as shown in Figure 4D. The installer uses a tool (not shown) to press on the top surface of the cap. The projections 1421 escape from the grooves so that the cap 142 falls downwardly in the housing 141. At the same time, the U-slots 1431a have a function to split the insulation of the wires and achieve the electrical connection between the wires and the contact pieces.
  • Figure 4e shows the final state while the IDC unit 14 is positioned in the supporting member 10 to achieve an intermediate connection.
