Abstract

There is described a clocking angle setting tool for a wire harness having a support arm provided with a clamp for attaching a harness cable of the wire harness to the support; arm, a connector receptacle for receiving a connector provided at the end of the harness cable and a key or keyway for engaging with a complementary keyway or key of the connector. The connector receptacle is spaced from the clamp and is rotatably mounted to the support arm. A locking mechanism for locking an angular position of the connector receptacle relative to the support arm is included. The angular position of the connector receptacle relative to the support arm determines a clocking angle of the connector relative to the harness cable.

First claim

The invention claimed is:

1. A clocking angle setting tool for a wire harness, comprising:
a support arm provided with a clamp for attaching a harness cable of the wire harness to the support arm;
a connector receptacle for receiving a connector provided at the end of the harness cable and having a key or keyway for engaging with a complementary keyway or key of the connector, wherein the connector receptacle is spaced from the clamp and is rotatably mounted to the support arm; and
a locking mechanism for locking an angular position of the connector receptacle relative to the support arm;
wherein the angular position of the connector receptacle relative to the support arm determines a clocking angle of the connector relative to the harness cable,
wherein the locking mechanism comprises an indexing mechanism which is configured to bias the connector receptacle to a plurality of discrete angular positions, and
wherein the indexing mechanism is a ratchet.

2. A clocking angle setting tool as claimed in claim 1 , wherein the locking mechanism comprises a pair of clamp plates and wherein a base portion of the connector receptacle is sandwiched between the clamp plates, the clamp plates being movable relative to one another to selectively grip the base portion between the clamp plates.

3. A clocking angle setting tool as claimed in claim 2 , wherein the clamp plates are joined by a pair of threaded fasteners.

4. A clocking angle setting tool as claimed in claim 1 , wherein the ratchet comprises a gear having a plurality of asymmetrical teeth and a pawl which is configured to engage the teeth.

5. A clocking angle setting tool as claimed in claim 4 , wherein the gear is formed by a base portion of the connector receptacle.

6. A clocking angle setting tool as claimed in claim 1 , wherein the discrete angular positions are 5° increments.

7. A clocking angle setting tool as claimed in claim 1 , wherein one of the support arm and the connector receptacle is provided with a dial having a graduated scale and the other of the support arm and the connector receptacle is provided with a pointer for indicating the angular position of the connector receptacle on the graduated scale.

8. A method of setting a clocking angle of a wire harness, the method comprising:
providing a clocking angle setting tool comprising: a support arm and a connector receptacle which is rotatably mounted to the support arm;
setting an angular position of the connector receptacle relative to the support arm and locking the angular position of the connector receptacle relative to the support arm with a locking mechanism comprising a ratchet which is configured to bias the connector receptacle to a plurality of discrete angular positions;
clamping a harness cable of the wire harness to the support arm;
attaching a connector provided at the end of the harness cable to the connector receptacle with a key or keyway of the connector engaging with a complementary keyway or key of the connector receptacle; and
with the connector receptacle in the set angular position, affixing the harness cable to the connector to set a clocking angle of the connector relative to the harness cable.

9. A method as claimed in claim 8 , wherein the harness cable is affixed to the connector using a heat-shrink boot.

10. A method as claimed in claim 8 , further comprising locking the connector receptacle in the set angular position by clamping a base portion of the connector receptacle between a pair of clamp plates.
