Claims

[Scope of utility model registration request]

In an oval-shaped die hole for compression connection of cable conductors, the oval-shaped die hole has an oval-shaped die hole for compressing a connecting sleeve into which both cable conductors to be connected are inserted, and the oval-shaped die hole has a diameter of It has a symmetrical shape, and the length R2 of the short axis of the oval die hole is selected to be approximately equal to the outer diameter of the connection sleeve after secondary compression, and the length Hl of the long axis is R2< H□≦1.03R2
The shape of the oval-shaped die hole was selected such that each surface of the circumferential length of 1 square between the end of the short axis and the end of the long axis is a first continuous die hole with the end of the short axis. a second surface portion continuous to the end of the long axis, and a third surface portion connecting the ends of the first and second surface portions, The radius of curvature P of the surface part is P=(0.75 to 0.8
5) The second surface portion is formed of an arcuate surface of R2, and the second surface portion is formed of a straight surface having a direction perpendicular to the long axis and a length of 2 to 3 mm from the end of the long axis. 3 is the outer diameter a of the connecting sleeve before primary compression (
0.65 to 0.85) An oval hole die for cable conductor compression connection, characterized in that it is formed of an arcuate surface with a length a and a radius of curvature Q.
