ABSTRACT:
An electric cable (2) includes a conductor (2a) which comprises a plurality of strands (21) and an insulation sheath (2b) which covers an outer periphery of the conductor (2a). An insulation displacement terminal (5) effects an insulation displacement connection with the conductor (2a) with the strands (21) being compressed into a slot width in which a contact resistance is in a stable area and the strands are not cut. The terminal (5) comprises: a slot (5a) having a given slot width (WS): a first pair of slopes (5b) opposed to each other and formed on an open part of the slot (5a) at an upper side with respect to an inserting direction of the electric cable (2), the first pair of slopes (5b) being adapted to guide the electric cable (2) into the slot (5a); and a second pair of slopes (5c) opposed to each other and formed on the open part of the slot (5a) at a lower side with respect to the direction of insertion of the electric cable. The second pair of slopes (5c) are adapted to compress and rearrange the strands (21) in the electric cable. The slot width (WS), an opening width (WS1) of the first pair of slopes (5b), an opening width (WS2) of the second pair of slopes (5c), an outer diameter (D) of the insulation sheath (2b) in the electric cable (2), and an outer diameter (d) of the conductor (2a) in the electric cable (2) are set to satisfy the following relationship:
