Abstract

A wire cutter, particularly for cutting electrical connection wires, comprising a hollow shaft rotatably guided in a sleeve. Respective ends of the sleeve and the shaft have end faces with cutting edges which extend partially parallel to the rotation axis.

Claims

1. A wire cutter especially adapted for cutting stranded wires comprising a circular cylindrical outer sleeve having an end face and a cutting edge extending parallel to the sleeve axis beyond the end face, a distal tip of the cutting edge being connected to the end face by a surface extending generally helically away from the cutting edge;

and a hollow cutting shaft arranged coaxially within said sleeve for rotation relative thereto and having a cutting edge extending to a distal tip at an axial location corresponding to said sleeve tip, said cutting edge extending parallel to the shaft axis at a region adjacent the shaft tip, said shaft cutting edge extending away from said tip and said region along an arch, adjacent said cutting edge said shaft having an end face so shaped that a wire portion to be cut is held inside a space between the shaft and sleeve, whereby rotation of the shaft relative to the sleeve for operative cutting engagement of said cutting surfaces against stranded wire cuts all strands of the wire, while application of suction through said hollow shaft will remove cut wire ends.

2. A wire cutter as claimed in claim 1 wherein said sleeve surface extends generally helically away from the cutting edge to a location approximately diametrically opposite the cutting edge and more remote from the tip than said end face, and continues in a reversed helical direction to said face.

3. A wire cutter as claimed in claim 1 wherein said shaft cutting edge extends, at the shaft tip, in a circumferential hook in the direction of the arch.
