## Abstract

An insulation displacement terminal is provided for terminating a conductor of an insulated electrical wire. The terminal has a channel-shaped terminating section of a generally U-shaped cross-section provided by a pair of side walls joined by a base wall. A U-shaped distal end of the terminating section includes a conductor-receiving insulation displacing slot extending into each side wall generally parallel to the base wall. Reinforcing flanges extend along free edges of the side walls of the terminating section to prevent collapsing thereof when the conductor is forced into the slots.

## Claims

### Claim 1

In an insulation displacement terminal for an insulated electrical wire, including a channel-shaped terminating section of a generally U-shaped cross-section provided by a pair of side walls joined by a base wall, a U-shaped distal end of the terminating section including a conductor-receiving insulation-displacing slot extending into each side wall of the section generally parallel to the base wall thereof, wherein the improvement comprises reinforcing means along free edges of said side walls of the terminating section of the terminal, said reinforcing means extend generally parallel to the slots, and
wherein said reinforcing means comprises elongated flanges projecting from the side walls generally parallel to the base wall.

### Claim 2 (depends on 1)

In an insulation displacement terminal as set forth in claim 1, wherein said flanges project inwardly toward each other.

### Claim 3

An insulation displacement terminal for terminating a conductor of an insulated electrical wire, comprising:
a mating section at one end of the terminal for engaging a complementary electrical contact means;
a terminating section at an opposite end of the terminal for insulation displacement termination with the conductor of the insulated electrical wire;
an intermediate section between the mating section and the terminating section for mounting the terminal in an appropriate connector housing; and
said terminating section being channel-shaped with a generally U-shaped cross-section provided by a pair of side walls joined by a base wall, the side walls being generally planar and a U-shaped distal end of the terminating section including a conductor-receiving insulation-displacing slot extending into each planar side wall generally parallel to the base wall, and reinforcing means along free edges of the side walls to prevent free arm portions of the side walls outside the slots from collapsing under forces from a conductor inserted into the slots, said reinforcing means extend generally parallel to the slots,
wherein said reinforcing means comprises elongated flanges projecting from the side walls generally parallel to the base wall, and
wherein said flanges project inwardly toward each other.
