Based on ideas from the images at the below URLs, we recently made an automated hi-cycle connector tester using an old sewing machine (where eccentric motion was used to compress a spring that was use as a constant force ref) and a 34970A data logger.

After the tests are complete, I intend to remove the force reference spring and use this test platform to 'motivate' members of the sales/marketing dept... luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Geetha Balasubramanian Sent: Monday, October 22, 2007 1:20 AM To: [email protected] Subject: Connector testing - is it possible for insertion /eomval with predefined force? Dear Experts, One of our customer wants us to perform a reliability / durability test on a connector pair used in the product as specified below. 1. Mate / unmate the connectors with a force of 4 N for 100 times. 2. Mate / unmate the connectors with a force of 6 N for 100 times. 3. Mate / unmate the connectors with a force of 8 N for 100 times. 4. Mate / unmate the connectors with a force of 10 N for 100 times. I have contacted 2 labs and they are not able to help here. These 2 labs say that they have provisions to vary the mating / unmating velocity but not the force. I request the forum members to show me a lab that tkae up this testing.
