Test Report for S9101-46R EZ-PCB Contact Clip Mechanical & Electrical
1. Introduction.
1.1.
Description and Purpose.
The following tests were performed on the S9101-46R SMT Contact Clip to test for Deflection
forces along with Insertion and Withdrawal forces before and after deflection, Temperature
rise and contact resistance.
1.2. Conclusion.
The following test data has been taken from Harwin test report 555, 589 and 591.
The force deflection data was used to determine the deflection required to produce a nominal
1N at the contact point; determined as sufficient force to produce a sound electrical contact on
the plated surface. With this confirmed; using the minimum specified pin diameter of
Ø1.10mm OR 1.10mm Square, the contact force would provide a stable connection.
With up to four cycles on the same contact, little change in insertion/withdrawal force values
was evident, thus confirming a stable performance.
The measured contact insertion and withdrawal forces are satisfactory for this type of contact,
which is likely to be used in isolation or with small numbers of other contacts, providing
sufficient retention for general purpose applications. Temperature rise of the component at
10A exceeds 30°C, therefore Harwin recommend the maximum current to be used is 9A.
Contact resistance testing shows that this contact is confirmed to have low contact resistance.
2. Test Method, Requirements and Results.
2.1. List of Test Samples.
Six different samples of S9101-46R were used for the first three tests, ten further samples
were used for temperature rise, and a final three samples were used for contact resistance.
2.2. Specification Parameters.
The purpose of this test was to determine the future specification of this product, so no initial
target figures existed for the contact.
2.3. Test Method and Results.
a)
Deflection forces.
The contact beam was supported such that the normal force required to deflect one
contact beam could be measured at specific deflections.
