Abstract

A terminal cutter includes a tool frame having a first cutting member coupled to an upper handle having a first cutting surface for cutting a terminal from a carrier strip and a second cutting member coupled to a lower handle having a second cutting surface for cutting the terminal from the carrier strip. A terminal strip guide assembly is coupled to the upper handle and/or the lower handle offset from the first and second cutting members. The terminal strip guide assembly includes a strip guide having a slot receiving the carrier strip and having a guide surface adjacent the slot. The guide surface is configured to engage the terminal to locate the terminal relative to the terminal strip guide assembly and to control a depth of the carrier strip received in the slot.

First claim

What is claimed is:

1. A terminal cutter comprising:
a tool frame having an upper handle and a lower handle extending rearward from a front of the tool frame, the upper handle extending along an upper handle axis and the lower handle extending along a lower handle axis, the upper handle and the lower handle being movable relative to each other at a pivot axis, the pivot axis being perpendicular to the upper handle axis and the lower handle axis, the tool frame having a first side and a second side;
a first cutting member coupled to the upper handle and having a first cutting surface defining a cutting edge for cutting a terminal from a carrier strip carrying a plurality of terminals, the first cutting surface being oriented generally perpendicular to the upper handle axis, the first cutting surface being oriented generally parallel to the pivot axis, the first cutting surface extending across the tool frame between the first side and the second side;
a second cutting member coupled to the lower handle and having a second cutting surface defining a cutting edge for cutting the terminal from the carrier strip, the second cutting surface being oriented generally perpendicular to the lower handle axis, the second cutting surface being oriented generally parallel to the pivot axis, the second cutting surface extending across the tool frame between the first side and the second side; and
a terminal strip guide assembly coupled to at least one of the upper handle and the lower handle and offset from the first and second cutting members, the terminal strip guide assembly comprising a strip guide having a slot for receiving the carrier strip, the slot extending along an axis oriented parallel to the cutting edges defined by the first cutting surface and the second cutting surface, the axis of the slot is oriented generally parallel to the pivot axis, the strip guide having a guide surface outside of the slot, wherein the guide surface is configured to engage the terminal to locate the terminal relative to the terminal strip guide assembly and to control a depth of the carrier strip received in the slot, the guide surface being generally perpendicular to the lower handle axis and generally parallel to the cutting surfaces defined by the first cutting surface and the second cutting surface.

2. The terminal cutter of claim 1 , wherein the guide surface is configured to engage and locate insulation barrel tabs of the terminals to locate the carrier strip in the slot at a predetermined depth within the slot such that the carrier strip does not bottom out in the slot.

3. The terminal cutter of claim 1 , wherein the guide surface is axially offset with respect to the first and second cutting surfaces such that the terminal aligned with the first and second cutting members being cut from the carrier strip is axially offset from the strip guide.

4. The terminal cutter of claim 1 , wherein the strip guide includes a top, a bottom, a front, a rear, a first side and a second side, the guide surface being provided at the front above the slot, the guide surface extending an entire length of the strip guide between the first side of the strip guide and the second side of the strip guide, the first cutting member and the second cutting member being provided at the second side of the strip guide.

5. The terminal cutter of claim 1 , wherein the strip guide includes a platform forward of the slot, the platform configured to support the terminals extending from the carrier strip, the guide surface being located above the platform.

6. The terminal cutter of claim 1 , wherein the terminal strip guide assembly includes a guide blade coupled to the strip guide and facing the guide surface such that a gap is defined between the guide blade and the guide surface for receiving a portion of the terminal, the guide blade being configured to engage the terminal to locate the terminal relative to the terminal strip guide assembly to control the depth of the carrier strip received in the slot.

7. The terminal cutter of claim 6 , wherein the guide surface and the guide blade are configured to confine lateral movement of the carrier strip and the terminals in a direction parallel to the terminals to control the depth of the carrier strip received in the slot.

8. The terminal cutter of claim 1 , wherein the terminal strip guide assembly includes an adjustment plate coupled to the strip guide and a guide blade coupled to the adjustment plate and facing the guide surface across a gap receiving a portion of the terminal, the adjustment plate being adjustable relative to the strip guide to adjust a lateral position of the guide blade with respect to the guide surface to control a width of the gap.

9. The terminal cutter of claim 8 , wherein the guide blade is adjustably coupled to the adjustment plate to adjust a vertical position of the guide blade relative to the terminals.

10. The terminal cutter of claim 1 , further comprising a terminal stop positioned adjacent the first and second cutting members, the terminal stop having a stop surface configured to engage the terminal being removed from the carrier strip to locate the terminal in alignment with the first and second cutting surfaces.

11. The terminal cutter of claim 1 , wherein the terminal strip guide assembly is coupled to at least one of the first cutting member and the second cutting member using fasteners.

12. A terminal cutter comprising:
a tool frame having an upper handle and a lower handle extending rearward from a front of the tool frame, the upper handle extending along an upper handle axis, the lower handle extending along a lower handle axis, the upper handle and the lower handle being movable relative to each other at a pivot axis, the pivot axis being perpendicular to the upper handle axis and the lower handle axis, the tool frame having a first side and a second side;
a first cutting member coupled to the upper handle and having a first cutting surface defining a cutting edge for cutting a terminal from a carrier strip carrying a plurality of terminals, the first cutting surface being oriented generally perpendicular to the upper handle axis, the first cutting surface being oriented generally parallel to the pivot axis, the first cutting surface extending across the tool frame between the first side and the second side;
a second cutting member coupled to the lower handle and having a second cutting surface defining a cutting edge for cutting the terminal from the carrier strip, the second cutting surface being oriented generally perpendicular to the lower handle axis, the second cutting surface being oriented generally parallel to the pivot axis, the second cutting surface extending across the tool frame between the first side and the second side; and
a terminal strip guide assembly coupled to at least one of the upper handle and the lower handle, the terminal strip guide assembly comprising a strip guide and a guide blade coupled to the strip guide, the strip guide having a slot for receiving the carrier strip, the slot extending along an axis oriented parallel to the cutting edges defined by the first cutting surface and the second cutting surface, the strip guide including a platform forward of the slot, the platform configured to support the terminals extending from the carrier strip, the strip guide having a rear guide surface located above the platform and the guide blade having a front guide surface located above the platform, a gap being defined between the rear guide surface and the front guide surface, the front guide surface and the rear guide surface extending parallel to the cutting edges defined by the first cutting surface and the second cutting surface
