Soldering

The alternative to crimping is to solder all cable strands within the contact barrel. When using an open flame, make sure that you

are not in an area where explosive gasses are present. The right proportion of solder is essential if this procedure is employed.

Use a quality 60/40 solder (60 percent tin, 40 percent lead) in wire form with a rosin flux core. Cable strands should be separately

fluxed with rosin paste, and the contact should be held in a vise with the barrel end facing up. Apply heat to the outside of the

barrel while the solder flows in beside the wire strands.

Here are some things to avoid when soldering:

A. Don’t use too much solder, to the point that it flows out of the contact barrel.

B. Don’t allow flux or solder on the outside of the contact. This will interfere with contact mounting within the installation or

with the contact connection to a mating connector.

C. Don’t overheat and cause excessive solder to “wick” up into the cable and stiffen it. This could interfere with contact

flexibility when connectors are mated.

D. Don’t solder when contact is in the connector housing. Solder away from the housing and then insert the contact into the

housing after it has cooled.

NOTE: Underwriters Laboratories (UL) requires the use of a cable clamp for soldered connections to unsupported wires.

| Determining If A Good Crimp Has Been Made |

1. Assure the correct wire size and type is used for the specific contact being crimped.

2. Follow the assembly instructions for the connector. Special attention should be paid to wire preparation and stripping.

3. Use the correct application tooling as recommended by Anderson Power Products® (tool, die, & locator).

4. Make several crimps for testing, and record crimp

dimensions in both “x” and “y” planes.

5. Test the electrical resistance across a mated pair

of connectors to the standard of the information

provided on the data sheet.

a. The electrical resistance values should be

similar to (or less than) what we publish for

that connector in our catalogs. Please

see the “Avg. Mated Contact Resistance”

on the data sheet for the specific

connector.

6. Test the pull out strength per the table to the right.

a. To achieve the electrical performance

published in our literature the pull out

values at minimum should meet the UL

486A values for the wire size being used.

The first column (lower value) pull out is the

minimum per UL486A. The second column

is what APP tries to achieve when designing

our crimp solutions. Any force within this

range is acceptable.

7. If crimps are within electrical and mechanical

specifications then the crimp dimensions are suitable

to be used as a secondary inspection criteria.
