TE Connectivity

 

TE Connectivity (TE) has introduced a range of spring fingers which have a smallfootprint to enable the system designer to save PCB space.

Spring fingers (also known as shield fingers, grounding springs, universal ground contacts or antenna clips) can be used in all types of small PCBs. A spring finger is a single-contact, surfacemount internal connector which may be used for antenna feeds, low-voltage electrical connections, grounding or shielding.

They help to reduce the level of EMI and static caused by connectors at devices that vibrate, such as speakers, motors and microphones.

TE’s ultra-small contact spring fingers are intended for use in the most space-constrained device designs. They feature a closed-loop contact design which ensures reliable connection to the PCB while providing a higher current rating of 1.5A.

Their robust side wall minimizes the scope for over-compression. In addition, a special anti-lifting design improves assembly efficiency by locking the tip of the contact within the sidewall of the spring finger, which helps to prevent the contact from getting caught on an operator’s glove.
