Application Specification

Pre-Insulated Diamond Grip (PIDG*)

NOTE

All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters [and

inches]. Unless otherwise specified, dimensions have a tolerance of +0.13 [+.005] and angles have a tolerance of +2 .

Figures and illustrations are for identification only and are not drawn to scale.

1. INTRODUCTION

This specification covers the requirements for application of PIDG terminals, splices, and end caps in various

operating environments. Each consists of a precision–formed metal wire barrel and a copper sleeve encased in

insulating material made of nylon, polyvinyl chloride (PVC) or polyvinyl fluoride (PVF

). The insulation is color

coded (solid primary color or a primary color with a color stripe) to correspond with a specific wire size or wire

size range. The terminals, splices, and end caps accept a combination of solid and stranded wire. The wire

barrel contains serrations that provide maximum contact and tensile strength after crimping the terminal, splice,

or end cap onto the wire. The terminals are available with a variety of tongue lengths and configurations; and

the terminals, splices, and end caps are available with various wire barrel lengths and diameters to

accommodate different wire sizes, wire types, and combination of wire sizes.

The terminals, splices, and end caps are available in loose piece form to be terminated with manual and

pneumatically–powered hand held tools and tape mounted to be terminated with bench mount semi–automatic

machines.

When corresponding with personnel, use the terminology provided in this specification to facilitate your

inquiries for information. Basic terms and features of this product are provided in Figure 1.

NOTE

The wire conductor(s) must not be nicked, scraped, or cut during the stripping operation.

3.4. Wire Placement

The stripped wire must be inserted into the wire barrel until the wire insulation is against the wire barrel but not

inside it. The wire insulation must be inside the metal sleeve. A gap between the wire insulation and wire barrel

is allowed, but not to exceed the dimension given in Figure 3.

3.5. Crimp Requirements

A. Crimp Height

The spring–back of the terminal, splice, or end cap insulation prevents an accurate direct measurement of

crimp height. However, crimping a slug of solder (60% tin and 40% lead) with a diameter slightly larger

than the conductor outside diameter can verify proper termination. The crimp height of the resulting solder

slug can be checked with a standard micrometer or comparator. The measurement must be made over

the most compressed area of the solder slug. See Figure 4.

NOTE

Some tooling with multiple crimping chambers form an embossed dot code in the terminal, splice, or end cap

insulation that indicates which crimping chamber was used. This dot code can be used as a visual inspection to ensure

that the correct wire size and crimping chamber were used.

The resilience of the splice insulation prevents accurate direct measurement of crimp height. Crimp height can be

obtained by measuring a crimped solder slug (60% tin and 40% lead) with a diameter comparable to the wire size.

The slug must be measured over the most compressed area of the slug with a standard micrometer or crimp height

comparator (refer to 408-7424 for specific instructions). The solder slug diameter and crimp height must be within the

dimensions provided in Figure 4.

B. Wire Barrel Crimp Profile and Location

The wire barrel crimp produced by the tooling (dies, heads, hand tools, pneumatic tools, or machines)

must be either a confined crescent crimp which appears as a depressed oval shape or a flat rectangular

crimp over the center of the wire barrel. The crimp must be evenly formed. Refer to Figures 4, 5, and 11.

Crescent crimp tooling produces the crescent crimp, and TETRA–CRIMP tooling produces the flat

rectangular crimp. For a tooling–to–crimp profile cross–reference, refer to Figure 10.

C. Dot Code

The dot code on the insulation must be well formed and correspond with the wire size or color code

marking on the crimping chamber of the tooling used. See Figures 4 and 5.

D. Bellmouths

There shall be no rear bellmouth. The front bellmouth shall be evident on the top and bottom of the wire

barrel as shown in Figure 5. Also see Figure 11.
