Abstract

A die set adapted to remove an end of a substantially flat lug of an electrical connector. The die set includes a first die and a second die. The first die includes a first frame and a spring loaded member connected to the first frame. The first frame includes a first contact surface adapted to directly contact a first side of the lug. The second die includes a second frame having a second contact surface adapted to contact a second side of the lug at a position offset from the first contact surface. The spring loaded member is adapted to contact the first side of the lug directly opposite the second contact surface. The first and second contact surfaces are adapted to shear off the end of the lug from the electrical connector.

First claim

What is claimed is:

1. A die set adapted to remove a front end of a substantially flat lug of an electrical connector, the die set comprising:
a first die comprising a first frame and a spring loaded member connected to the first frame, wherein the first frame comprises a first contact surface adapted to directly contact a first side of the lug; and
a second die comprising a second frame having a second contact surface adapted to contact a second side of the lug at a position offset from the first contact surface,
wherein the spring loaded member is adapted to contact the first side of the lug directly opposite the second contact surface, and wherein the first and second contact surfaces are adapted to shear off the front end of the lug from the electrical connector, wherein the first frame has a first stepped surface with a first shearing surface at the first stepped surface, wherein the second frame is a one-piece metal member, and where the spring loaded member is a sole spring loaded member of the die set and, wherein the second frame comprises a bottom step area providing space for partially receiving the first shearing surface and the front end of the flat lug when sheared off, the bottom step area open to at least one side of the second frame allowing the front end of the flat lug to exit the die set.

2. A die set as in claim 1 wherein the spring loaded member is located in a bottom step area of first frame and the first contact surface is at a top step area of the first frame.

3. A die set as in claim 2 wherein the second frame has a second stepped surface with a second shearing surface at the second stepped surface.

4. A die set as in claim 1 wherein the one-piece metal member has a stepped surface with a shearing surface between steps of the stepped surface.

5. A die set as in claim 1 wherein the first contact surface is located laterally offset from the second frame.

6. A tool comprising a working head comprising the die set of claim 1 at the working head.

7. A tool as in claim 6 further comprising:
a tool frame forming at least a portion of the working head;
a hydraulic drive system in the tool frame; and
a ram movably mounted to the tool frame,
wherein the dies of the die set are respectively connected to the ram and the tool frame at the working head.

8. A die set comprising:
a first die comprising a first frame and a spring loaded member connected to the first frame, wherein the first frame comprises a first contact surface adapted to directly contact a front end of a first side of a substantially flat lug of an electrical connector; and
a second die comprising a second frame having a second contact surface adapted to contact a front end of a second side of the lug at a position offset from the first contact surface,
wherein the spring loaded member is adapted to contact the front end of the first side of the lug directly opposite the second contact surface, and wherein the first and second contact surfaces are adapted to shear off the front end of the lug from the electrical connector, where the first frame has a first shearing surface, where the spring loaded member is a sole spring loaded member of the die set, and where the die set is adapted to remove the front end of the substantially flat lug of the electrical connector where the second frame comprises a bottom step area providing space for partially receiving the first shearing surface and the front end of the flat lug when sheared off, the bottom step area open to at least one side of the second frame allowing the front end of the flat lug to exit the die set.
