Abstract

A wiring harness has a main bundle of leads disposed in an axially slit, corrugated tube and break-out leads disposed in a break-out protector which extends through the slit of the corrugated tube. The break-out protector is a one piece molding of thermoplastic material. It has a tubular body with an outwardly flared skirt at one end which is disposed in the corrugated tube. The tubular body has an axial slit and the annular skirt has a communication slot for assemblying the break-out protector around the break-out leads. The tubular body has wedge-shaped portions and the annular skirt has a wavy edge to assist in assembly.

Claims

1. A break-out protector for a wiring harness having a main bundle of leads disposed in an axially slit tube and a break-out lead or leads which extend through the slit of the axially slit tube, said break-out protector being a one piece molding of thermoplastic material comprising:

a tubular body having an outwardly flared skirt at one end,

a wedge-shaped portion in the wall of the tubular body for spreading the slit of the tube,

an axial slit through the wall of the tubular body which extends for the entire length of the tubular body to pass a break-out lead or leads into the tubular body,

a wavy edge on the annular skirt which has diametrically opposed dips which are coplanar with the wedge-shaped portion of the tubular body, and

a slot in the annular skirt which extends from the wavy edge to the axial slit of the tubular body.

2. A break-out protector for a wiring harness having a main bundle of leads disposed in an axially slit tube and a break-out lead or leads which extend through the slit of the axially slit tube, said break-out protector being a one piece molding of thermoplastic material comprising:

a tubular body of elliptic cross-section having an outwardly flared skirt at one end,

a leading wedge-shaped portion and a diametrically opposed trailing wedge-shaped portion in the wall of the tubular body for spreading the slit of the tube,

an axial slit through the wall of the tubular body which is at the apex of the trailing wedge-shaped portion and which extends for the entire length of the tubular body to pass a break-out lead or leads into the tubular body,

a wavy edge on the annular skirt which has diametrically opposed dips which are coplanar with the wedge-shaped portion of the tubular body, and

a triangular slot in the annular skirt which extends from one of the dips in the wavy edge to the axial slit of the tubular body.

3. The combination comprising:

a wiring harness having a main bundle of leads disposed in an axially slit, corrugated tube of stiff plastic material and a break-out lead or leads which extend through the slit of the corrugated tube, and

a break-out protector around the break-out lead or leads,

said break-out protector being a one piece molding of thermoplastic material and including;

a tubular body which is transverse to the corrugated tube and which has an outwardly flared skirt at one end which is disposed in the corrugated tube,

a wedge-shaped portion in the wall of the tubular body for spreading the slit of the corrugated tube,

an axial slit through the wall of the tubular body which extends for the entire length of the tubular body to pass the break-out lead or leads into the tubular body,

a wavy edge on the annular skirt which has diametrically opposed dips which are coplanar with the wedge-shaped portion of the tubular body,

and

a slot in the annular skirt which extends from the wavy edge to the axial slit of the tubular body.
