Contact Design

AS39029 QPL LISTED CONTACTS

The contact consists of three parts, separately manufactured and made of different base materials. This design allows to optimise the performance and to select the most appropriate production process individually:
 

• Contact body made of machined brass
• Beryllium-copper clip insert achieved by precision stamping process
• Protection hood made of deep-drawn stainless steel

Separate electroplating processes of body and clip allow the best cost-performance ratio (localized finish). The assembly of the three parts is then carried out on dedicated, fully automatic assembly lines.

Reversed clip contacts are presently available in size 12, 16, 20 and 22. This proprietary technology developed by PRECI-DIP, is protected by international patents.

ADVANTAGES AND CHARACTERISTICS

In comparison with the alternative slotted contact body design, the reversed clip concept has several advantages:
 

• Smaller difference between insertion and extraction forces
• Reduced dispersion of the force values
• Higher redundancy of the contact points, thanks to 6 or 8 con-tact fingers

We are also manufacturing the corresponding precision-machined pin contacts.

These contacts have successfully passed all the qualification tests according to AS39029 and are QPL listed
