25 AUG 10 Rev HHand Crimping Tools 46073 and 46074

PROPER USE GUIDELINES

Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use and low volume

applications. A wide selection of powered application equipment for extended--use, production operations is available.

1. INTRODUCTION

Hand Crimping Tools 46073 and 46074 are designed

to crimp CERTI--SEAL* moisture proof splices onto

stranded copper wire sizes 24 through

16 AWG. Read these instructions carefully before

using the tool.

Dimensions in this instruction sheet are in metric

units [with U.S. customary units in brackets].

Figures are not drawn to scale.

Reasons for reissue of this instruction sheet are

provided in Section 6, REVISION SUMMARY.

2. DESCRIPTION (Figure 1)

The hand tools are designed with two indenter

(crimper) dies, two anvil (stationary) dies, a locator,

and a CERTI--CRIMP tool ratchet. When closed, the

dies form one crimping chamber. The ratchet assures

full crimping of the splice. Once engaged, the ratchet

will not release until the tool handles have been

FULLY closed.

The dies bottom before the ratchet releases. This

design feature ensures maximum electrical and

tensile performance of the crimp. Do NOT

re--adjust the ratchet.

3. CRIMPING PROCEDURE

Each hand tool is coated with a preservative to

prevent rust or corrosion. Wipe this preservative

from the tool, particularly from the dies, before

using the tool.

1. Select the correct splice for the wire size and

wire insulation diameter being used. Observe color

coding of splice, rings, adaptors, and tools. See

Figure 2.

2. Strip the wire to dimensions listed in Figure 2.

Do NOT nick or cut the wire strands.

3. Open the dies by squeezing the tool handles

together until the ratchet releases.

4. Select the proper color--coded end of splice

(when applicable) for the wire insulation diameter

being used. See Figure 2.

5. Insert stripped wire into splice until it bottoms

against wire stop. End of conductor should be

visible through transparent window indent of splice.

6. Align splice window indents with tool locator,

and push splice into locator until splice bottoms.

SeeFigure3.

7. Hold wire in place and squeeze tool handles

together until the CERTI--CRIMP ratchet releases.

Allow tool handles to open FULLY. Crimped splice

may be removed.

8. To crimp other half of splice, position uncrimped

half in tool and follow same procedure used to

crimp first half of splice. If splice cannot be turned,

turn tool around.

9. Refer to Figure 4 for splice crimp inspection.

4. MAINTENANCE AND INSPECTION

Tyco Electronics recommends that a maintenance

and inspection program be performed periodically to

ensure dependable and uniform terminations.

Frequency of inspection depends on:

1. The care, amount of use, and handling of the

hand tool.

2. The presence of abnormal amounts of dust and

dirt.

3. The degree of operator skill.

4. Your own established standards.

408- 1536

Hand Crimping Tools 46073 and 46074

The hand tool is inspected before being shipped from

the plant; however, it is recommended that the tool be

inspected immediately upon arrival to ensure that the

tool has not been damaged during shipment.

Wire ends should butt against wire stop; however,

application is acceptable if wire ends are flush with or

protrude beyond inside ends of wire barrels.

Observe crimped rings for splitting. split rings indicate

possible damaged dies or wire insulation diameter is too

large (refer to Figure 2). Conductor strands may fracture

if over--sized insulation diameter is used.

Crimping Inspection

Due to the precision design, it is important that

no parts of these tools be interchanged except

those replacement parts listed in Figure 7.

4.1. Daily Maintenance

1. Remove dust, moisture, and other contaminants

with a clean brush, or a soft, lint--free cloth. Do

NOT use objects that could damage the tool.

2. Make certain that the retaining pins are in place

and that they are secured with retaining rings.

3. All pins, pivot points, and bearing surfaces

should be protected with a thin coat of any good

SAE 20 motor oil. Do NOT oil excessively.

4. When the tool is not in use, keep handles closed

to prevent objects from becoming lodged in the

dies. Store the tool in a clean, dry area.

4.2. Lubrication

Lubricate all pins, pivot points, and bearing surfaces

with SAE 20 motor oil as follows:

Tool used in daily production—lubricate daily

Tool used daily (occasional)—lubricate weekly

Tool used weekly—lubricate monthly

Wipe excess oil from tool, particularly from crimping

area. Oil transferred from the crimping area onto

certain terminations may affect the electrical

characteristics of an application.

4.3. Periodic Inspection

1. Hand tool should be immersed (handles partially

closed) in a reliable commercial degreasing

compound to remove accumulated dirt, grease,

and foreign matter.

2. Close tool handles until ratchet releases and

then allow them to open freely. If they do not open

quickly and fully, the spring is defective and must

be replaced. See Section 5, REPLACEMENT AND

REPAIR.

3. Inspect head assembly for worn, cracked, or

broken dies. If damage is evident, see Section 5,

REPLACEMENT AND REPAIR, for information on

obtaining customer repair service.

A. Gaging the Crimping Chamber

This inspection requires the use of a plug gage

conforming to the dimensions provided in Figure 5.

Tyco Electronics does not manufacture or market

these gages. To gage the crimping chamber, proceed

as follows:

1. Remove traces of oil or dirt from the crimping

chamber and plug gage.

2. Close the tool handles until it is evident that the

dies have bottomed; then hold in this position. Do

NOT force the dies beyond initial contact.

3. Align the GO element with the wire barrel

crimping section. Push element straight into the

crimping chamber without using force. The GO

element must pass completely through the

crimping chamber. See Figure 6.

4. Align the NO--GO element and try to insert it

straight into the same crimping chamber. The

NO--GO element may start entry, but must not

pass completely through the crimping chamber.

SeeFigure6.

5. With dies bottomed, check insulation (ring)

crimping section using the appropriate plug gage in

same manner as Steps 3 and 4.

If the crimping chamber conforms to the gage

inspection, the tool is considered dimensionally

correct, and should be lubricated with a THIN coat of

any good SAE 20 motor oil. If not, refer to Section 5,

REPLACEMENT AND REPAIR, for information on

obtaining further evaluation and repair.

For additional information regarding the use of a plug

gage, refer to instruction sheet 408--7424.

B. CERTI- CRIMP Ratchet Inspection

The CERTI--CRIMP tool ratchet on these hand tools

should be checked to ensure that the ratchet does not

release prematurely, allowing the dies to open before

they have fully bottomed. Obtain a 0.025--mm

[.001--in.] shim that is suitable for checking the

clearance between the bottoming surfaces of the

dies. Proceed as follows:

1. Refer to Figure 2, and select a splice and

maximum size wire for the tool.

2. Position the splice and wire between the dies,

as described in Section 3, CRIMPING

PROCEDURE.

3. Hold the wire in place and squeeze the handles

until the ratchet releases. Hold the handles in this

position, maintaining just enough tension to keep

the dies closed.

4. Check the clearance between the bottoming

surfaces of the dies. If the clearance is 0.025 mm

[.001 in.] or less, the ratchet is satisfactory. If

clearance exceeds 0.025 mm [.001 in.], the ratchet

is out of adjustment and must be repaired. See

Section 5, REPLACEMENT AND REPAIR.
