Abstract

A terminal locator for holding a terminal in a crimping zone of a terminal crimping device includes a housing configured to be positioned forward of crimp tooling defining the crimping zone. The housing has a terminal cavity extending along a terminal axis configured to receive the terminal such that a crimp barrel of the terminal extends rearward of the housing along the terminal axis into the crimping zone for crimping to a wire. A spacer is held by the housing. The spacer has a spacer blocking surface configured to locate the terminal and block axial rearward movement of the terminal. A latch is held by the housing. The latch is deflectable to allow insertion and removal of the terminal from the terminal cavity, the latch having a latch blocking surface configured to locate the terminal and block axial forward movement of the terminal.

First claim

What is claimed is:

1. A terminal locator for holding a terminal in a crimping zone of a terminal crimping device, the terminal locator comprising:
a housing configured to be positioned forward of crimp tooling defining the crimping zone, the housing having a terminal cavity extending along a terminal axis and configured to receive the terminal such that a crimp barrel of the terminal extends rearward of the housing along the terminal axis into the crimping zone for crimping to a wire;
a spacer held by the housing, the spacer having a spacer blocking surface configured to locate the terminal and block axial rearward movement of the terminal; and
a latch held by the housing, the latch being deflectable to allow insertion and removal of the terminal from the terminal cavity, the latch having a latch blocking surface configured to locate the terminal and block axial forward movement of the terminal.

2. The terminal locator of claim 1 , wherein at least one of the housing, spacer and latch include an anti-rotation surface configured to engage the terminal in the terminal cavity and block rotation of the terminal about the terminal axis.

3. The terminal locator of claim 1 , wherein the spacer is movable relative to the housing.

4. The terminal locator of claim 1 , wherein the housing includes guide channels, the spacer includes guide pins received in the guide channels, the spacer being movable relative to the housing with the guide pins guiding movement of the spacer as the guide pins move in the guide channels.

5. The terminal locator of claim 1 , wherein the latch is received in a latch opening, the latch being movable relative to the housing in the latch opening.

6. The terminal locator of claim 1 , wherein the latch is movably coupled to the spacer.

7. The terminal locator of claim 1 , wherein the latch blocking surface is axially offset with respect to the spacer blocking surface.

8. The terminal locator of claim 1 , wherein the latch includes an angled undercut along a rear edge of the latch, the rear edge at the angled undercut defining the latch blocking surface configured to engage an angled forehead of the terminal.

9. The terminal locator of claim 1 , wherein the latch includes an angled ramp, the terminal being driven into the ramp during insertion or removal to force the latch to deflect outward relative to the terminal cavity to allow insertion or removal of the terminal.

10. The terminal locator of claim 1 , wherein the housing includes a ledge in the terminal cavity defining an anti-rotation surface configured to engage the terminal and block rotation of the terminal about the terminal axis.

11. The terminal locator of claim 1 , wherein the spacer includes a U-shaped channel configured to receive the terminal and engage the terminal to stop axial and rotational movement of the terminal.

12. The terminal locator of claim 1 , wherein the latch defines a first latch, the terminal locator further comprising a second latch held by the housing on an opposite side of the terminal cavity from the first latch.

13. The terminal locator of claim 1 , wherein the housing includes a spacer channel receiving the spacer, the spacer being movable perpendicular to the terminal axis in the spacer channel.

14. The terminal locator of claim 13 , wherein the housing includes a spring plate having a ratchet configured to hold the spacer at a plurality of predefined positions relative to the housing.

15. The terminal locator of claim 13 , wherein the spacer is movable between an unlocked position and a locked position, the latch being open in the unlocked position and the latch being closed in the locked position, the terminal cavity configured to receive the terminal in the unlocked position, the latch configured to retain the terminal in the terminal cavity in the locked position.

16. The terminal locator of claim 15 , wherein the latch is movably coupled to the spacer, the housing including a profiled ledge in the spacer channel configured to engage the latch and force the latch to the closed position when the spacer and the latch are moved in the spacer channel from the unlocked position to the locked position.

17. A terminal crimping device that crimps a terminal to a wire, the terminal crimping device comprising:
crimp tooling including a movable ram and an anvil defining a crimping zone, the movable ram being movable along a crimp stroke towards and away from the anvil, the crimp tooling crimping the terminal to the wire during the crimp stroke; and
a terminal locator configured to hold the terminal in the crimping zone during the crimp stroke, the terminal locator comprising:
a housing positioned forward of the crimp tooling defining the crimping zone, the housing having a terminal cavity extending along a terminal axis and configured to receive the terminal such that a crimp barrel of the terminal extends rearward of the housing along the terminal axis into the crimping zone;
a spacer held by the housing, the spacer having a spacer blocking surface configured to locate the terminal and block axial rearward movement of the terminal; and
a latch held by the housing, the latch being deflectable to allow insertion and removal of the terminal from the terminal cavity, the latch having a latch blocking surface configured to locate the terminal and block axial forward movement of the terminal.

18. The terminal crimping device of claim 17 , wherein the terminal locator is coupled to a front end of the anvil.

19. The terminal crimping device of claim 17 , wherein the spacer is movable relative to the housing.

20. A crimping system comprising:
a driving mechanism driven in an axial driving direction during a crimping operation;
crimp tooling including a movable ram and an anvil defining a crimping zone, the movable ram being coupled to the driving mechanism and movable along a crimp stroke towards and away from the anvil by the driving mechanism during the crimping operation, the crimp tooling crimping the terminal to the wire during the crimp stroke; and
a terminal locator configured to hold the terminal in the crimping zone during the crimp stroke, the terminal locator comprising:
a housing positioned forward of the crimp tooling, the housing having a terminal cavity extending along a terminal axis and configured to receive the terminal such that a crimp barrel of the terminal extends rearward of the housing along the terminal axis into the crimping zone;
a spacer held by the housing, the spacer having a spacer blocking surface configured to locate the terminal and block axial rearward movement of the terminal; and
a latch held by the housing, the latch being deflectable to allow insertion and removal of the terminal from the terminal cavity, the latch having a latch blocking surface configured to locate the terminal and block axial forward movement of the terminal.
