Contact Retention (Pushback) Problems

Cable/Harness Testing Made Easy.

Do you work with crimp and poke style connectors? If so, you've likely seen problems with contact retention, or "pushback" failures. When contacts are not fully seated they can be pushed back during mating, creating a defective cable/harness. Our newsletter this month covers the many approaches to solving this problem.

If you have any questions or comments, call us at 1-800-441-9910.

There are many ways to prevent pushback of contacts inserted into connectors. IPC/WHMA A-620 section 19.7.5 defines "Contact Retention Verification" using "Push-Click-Pull" to be used for all classes of assemblies. In addition to operator training, learn how testing and connector design has been used to help solve contact retention problems in this month's Cirris e-newsletter.

Pin retention issues

Contact retention is vital for proper connections.

You can say that contact retention problems are training problems. Unfortunately, human beings remain error-prone. We introduced Pin-Sight, last month with its ability to help operators quickly find the right location to insert pins/contacts into connectors. You may have missed it, or particularly its ability to detect the "pull" of the push-click-pull process. Call for a Free in-house demo of Pin-Sight today and discover how your payback will be measured in months, not years, due to the quality and productivity improvements you'll see. To learn more about Pin-Sight see:
