Abstract

A connector 2 is shown in a position to be crimped to the multiple strands 3 and outer insulation 4 of a conductor 5. A conductor 5' and connector 2' (partly broken away) are shown assembled with tabs 6' gripping the strands 3' and tabs 7' gripping the insulation 4'. When the connector and the conductor are in position for crimping, a tool 8 is lowered to engage the fingers of tabs 7 between surfaces 9 to crimp them around the insulation, as shown at 7'. A similar tool (not shown) is located against the left face of tool 8 to similarly crimp tabs 6 around strands 3.

Crimping Apparatus with Wire Depressor

A connector 2 is shown in a position to be crimped to the multiple strands 3 and outer insulation 4 of a conductor 5. A conductor 5' and connector 2' (partly broken away) are shown assembled with tabs 6' gripping the strands 3' and tabs 7' gripping the insulation 4'. When the connector and the conductor are in position for crimping, a tool 8 is lowered to engage the fingers of tabs 7 between surfaces 9 to crimp them around the insulation, as shown at 7'. A similar tool (not shown) is located against the left face of tool 8 to similarly crimp tabs 6 around strands 3.

In using the tool conventionally, as just described, the strands 3 do not always lie within the tabs 6, as the drawing represents, and some of these loose strands may not be enclosed by tabs 6 after crimping. Tool 8 has an element 10 that is slidable in a groove between walls 12. A tab 13 on element 10 rides in a slot 14, and a spring 15 is compressed between tab 13 and a wall 16 of a groove in the tool. These components, shown in an exploded view, are held in position by the second tool (not shown) that is located to the left of tool 8. When tool 8 is lowered to crimp the tabs 7, element 10 engages any loose wires and forces them into the space between tabs 6 for the crimping operation. As crimping of tabs 6 and 7 takes place, element 10 slides upward in the groove in tool 8.
