Scalable Spring Finger Contacts (English)

TE Connectivity offers a wide selection of scalable spring fingers as well as a complete family of spring fingers in a variety of styles and sizes. For each type of spring finger, TE Connectivity stands out with advanced automated production facilities which enable stability, reliability and excellence.

Our innovative scalable family of spring fingers is available in heights from 1.0mm to 3.8mm. All these types can be mounted onto one single footprint, so the product can be easily swapped when the design change is required.

Let’s take a close look at a scalable spring finger.

• The preload function nearly doubles the working area of a common spring finger and increases contact force by 0.2N.
• The dimple on the contact enhances the contact force.
• The backward-vended tip prevents hooking.
• The pick-and-place area supports auto-assembly processes.
• The holes increase soldering strength and reduce solder wicking issues.

While TE’s portfolio of spring fingers is the largest in the market, we are adding new side-protected scalable spring fingers to address common customer issues around problems that occur when large quantities of spring fingers are used.

The new, enhanced sidewall design prevents springs from being tangled by operator gloves and avoids deflection during PCB transfer.

All our spring fingers require very limited space on a printed circuit board and accommodate soldering as well as pick and place using standard equipment.

With the launch of spring fingers across a variety of industries, we are ready to help you to reduce design cost and accelerate time to market.
