1. INTRODUCTION
This specification covers the requirements for application of Power Ring Connectors. The connectors are
designed to be mounted to the chassis of a household appliance.
Each connector consists of a housing, two copper tone terminals, one silver tone terminal, a ground strap
(optional), three screws, and three nuts. The housing features mounting holes and three terminal slots. The
terminals feature a locking lance, a wire barrel, an insulation support barrel, and a tab for a screw and nut.
There are wire barrel designs to cover a wire range of 18 through 10 AWG stranded copper wire. (Refer to the
specific customer drawing for the appropriate wire size range.) The tab end will accept stranded copper
household wire that is within a range of 6 through 10 AWG. This wire can be used unterminated, or it can be
terminated with any precision formed or custom--made terminal with a maximum thickness of 3.175 mm
[.125 in.]. See Figure 1 for optional Ring Tongue Terminal.
When corresponding with Tyco Electronics 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.

3.3. Crimp Requirements
A. Locking Lance
The end of the locking lance should be the dimension shown below the terminal tab plane as indicated in
Figure 3. Inspection of several un--crimped contacts will provide the required visual appearance before and
after crimping of a terminal.
B. Carrier Cutoff Tab and Burr Allowance
Neither cutoff tab shall extend beyond the side of the terminal and the maximum allowable burr on the
cutoff is provided in Figure 3.
C. Crimp Configuration and Location
The crimp applied to the wire portion of the terminal is the most compressed area, and is the most critical
to assure optimum performance of the termination. The effective length shall be as defined in Figure 3
(excluding bellmouths) over the length of the wire barrel.
The wire barrel will be crimped in the “F” Crimp configuration where the tips of the wire barrel will turn
inward and encapsulate all wire strands. The insulation support barrel may be crimped in the “F” or “O”
Crimp configuration where the tips of the insulation barrel will encapsulate the insulation and form the
insulation support. See Figure 3.
D. Wire Barrel Seam
The wire barrel shall be completely closed with no portion of the conductor protruding from the seam. The
crimp flash along the sides of the wire barrel that are caused by the crimping pressure and allowable
tolerances in the tool shall not exceed the dimension provided in Figure 3.
E. Conductor Location
The conductor of the wire may be flush to a protrusion of what is shown in Figure 3 from the front of the
wire barrel. Both insulation and conductor should be visible in the transition area between the insulation
and wire barrels. No insulation should be in the wire barrel.

A. Hole Layout
The mounting plane hole layout for the two offset mounting holes and the single ground strap is provided
in Figure 5.
NOTE
When selecting a location for the connector, the wire bend radius specified by the wire manufacturer must be
considered. Also, to permit attachment of the wire, there should be sufficient slack between the wire end and any
strain relief.

B. Attaching Hardware
Any commercially available hardware such as sheetmetal screws, bolts and nut, rivet or other hardware
that is compatible with the mounting plane may be used to secure the housing to the mounting plane.

3.5. Attaching Appliance and Household Wire
(Figures 6 and 7)
The household wire can be attached to the terminal tab as bare wire or with a terminal attached. Any precision
formed or custom--made terminal of 3.18 mm [.125 in.] maximum thickness may be used. See Figure 6 for the
Ring Tongue Terminal which may be used. Grounding the appliance through the ground wire (center/neutral
position) with the ground strap is optional. Figure 6 provides a composite of the various termination techniques.
The assembly procedures for all techniques are covered by the following text.
1. Crimp the appliance wire to the tab terminal wire and insulation barrels using the tooling and crimping
instructions packaged with the tooling.
2. Lay the appliance wire on the center of the terminal cavity then, guiding the terminal under the
terminal hold--downs, pull back on the wire until the terminal locking lance passes over the housing
locking rib and locks behind the rib.
