## Abstract

A high density connector for electrically connecting a high density cable to a matable electrical connector has a housing with a plurality of terminals provided therein. The terminals have sharp outer edges which enable the terminals to cooperate with a portion of the connector to provide the securing force required to retain the terminals in position. The positioning of the terminals in the housing is accurately controlled through the use of an alignment tool which is manufactured from a material which does not expand or contract when exposed to various environmental conditions. Therefore, the precise positioning of the terminals is guaranteed and is repeatable for many connectors.

## Claims

### Claim 1

An alignment tool for use in positioning terminals in an electrical connector, the alignment tool comprising:
a rearward surface and a forward surface, and end walls and side walls extending from the rearward surface to the forward surface;
terminal receiving recesses extending toward the rearward surface first to transverse bottom surfaces from the forward surface, and extending there beyond along the side walls, with dividers separating them;
positioning means positioned on the end walls, the positioning means cooperate with the electrical connector to insure that the alignment tool is properly positioned relative to the connector when the alignment tool is moved into cooperation with the connector.

### Claim 2 (depends on 1)

An alignment tool as recited in claim 1 wherein the alignment tool is modular, such that the alignment tool can be modified to allow the tool to be used for various sizes of connectors.

### Claim 3 (depends on 1)

An alignment tool as recited in claim 1 wherein the alignment tool is manufactured from precision ground steel so that the manufacturing tolerances can be minimized thereby enabling the tool to maintain the precise spacing required.

### Claim 4 (depends on 1)

An alignment tool as recited in claim 1 wherein the terminal receiving recesses are dimensioned to accept terminals therein, the terminals frictionally engage bottom surfaces of the terminal receiving recesses to maintain the terminals in position relative to the alignment tool, dividing walls are provided between the terminal receiving recess to prevent the movement of the terminals.

### Claim 5 (depends on 4)

An alignment tool as recited in claim 4 wherein the center line spacing of the terminal receiving recess is approximately 0.02 of an inch.
