Abstract

Devices and methods to facilitate separation of a crimped wire terminal from a tape terminal carrier strip. The devices and methods weaken the attachment between the crimped wire terminal and the tape terminal carrier strip to facilitate effective, efficient, and reliable removal of the crimped wire terminal from the tape terminal carrier strip.

Claims

1. An applicator for an electrical terminal crimping machine, said applicator comprising:

A feed mechanism, said feed mechanism being capable of advancing a tape terminal carrier strip, said tape terminal carrier strip having at least one wire terminal attached to said tape terminal carrier strip;

A press assembly having a press, said press being constructed so as to be moveable in the vertical direction; and

An anvil, said anvil being positioned vertically below said press assembly and having a crimp surface and a separation assistance device, said separation assistance device being located adjacent to said crimp surface.

2. The applicator recited in claim 1, wherein said separation assistance device has a ramp.

3. The applicator recited in claim 2, wherein said ramp has a rounded element.

4. The applicator recited in claim 1, wherein said separation assistance device has a traveling ramp.

5. The applicator recited in claim 4, wherein said traveling ramp is movable in the vertical direction.

6. The applicator recited in claim 4, wherein said traveling ramp has a rounded element.

7. The applicator recited in claim 1, wherein said separation assistance device has a cylindrical pin.

8. The applicator recited in claim 1, wherein said anvil has a mounting hole.

9. The applicator recited in claim 1, wherein said anvil has a key.

10. A method for separating a crimped wire terminal from a tape terminal carrier strip, comprising:

a. providing said tape terminal carrier strip which has at least one uncrimped wire terminal attached to said tape terminal carrier strip;

b. feeding said tape terminal carrier strip through an electrical terminal crimping machine so that said uncrimped wire terminal rests on the top surface of an anvil and directly under a press;

c. inserting a wire into a receiving end of said uncrimped wire terminal;

d. depressing said press in the downward vertical direction toward said anvil, whereby said uncrimped wire terminal will be fused to said wire to create a crimped wire terminal; and

e. advancing said tape terminal carrier strip so that a separation assistance device positioned on said anvil applies a force to said crimped wire terminal, whereby said force weakens the attachment between said crimped wire terminal and said tape terminal carrier strip.

11. A method as recited in claim 10, wherein said separation assistance device has a ramp.

12. A method as recited in claim 11, wherein said ramp has a rounded element.

13. A method as recited in claim 10, wherein said separation assistance device has a traveling ramp, said traveling ramp being movable in the vertical direction.

14. A method as recited in claim 13, wherein said traveling ramp has a rounded element.

15. A method as recited in claim 10, wherein said separation assistance device has a cylindrical pin.

16. An applicator for an electrical terminal crimping machine, said applicator comprising:

means for advancing a tape terminal carrier strip, said tape terminal carrier strip having at least one uncrimped wire terminal attached to said tape terminal carrier strip;

means for creating a crimp connection between said uncrimped wire terminal and a wire whereby the uncrimped wire terminal becomes a crimped wire terminal that is fused to the wire; and

means for weakening the attachment between said crimped wire terminal and said tape terminal carrier strip.
