Claims

[Scope of utility model registration request]

A clamp body having a wire gripping groove and a clamp cap are hinged together on one side of the wire gripping groove, a tightening rod passes through the clamp body on the other side of the wire gripping groove, and one end of the tightening rod is removed to the clamp cap. At the same time, a coil spring is arranged coaxially around the outer periphery of the part of the tightening rod that protrudes toward the clamp body, and the coil spring can be held at the other end of the tightening rod in a strongly compressed state and a weakly compressed state. (Including uncompressed, the same applies hereinafter.)
The eccentric cam that switches between the two states is pivotally supported.
This eccentric cam is formed in a U-shape so as to sandwich the tightening rod, and the outer periphery other than the bent part has a
A boltless wire clamp that has a cam surface consisting of a weak compression surface with a small distance from the shaft, an intermediate compression surface with a gradually increasing distance from the shaft, and a strong compression surface with a large distance from the shaft. , a boltless electric wire clamp characterized in that the strong compression surface of the eccentric cam is formed at an obtuse angle with respect to the back surface of the bent portion.
