GoPro 4 metal clips (behind the lens)

Hello guys, recently I damaged my GoPro badly and it didn't turn on afterwards. When I opened it up to check (not the first time though), I noticed one of the Metal Clip (Bronze /Gold color) was broken.

The position of the clip is at the top of the mainboard, near the Lens module. Please tell me what are those clips and what's the function. Is it to ground the power line or to complete the circuit inside.

This is a picture of it

Please help me. Thank you in advance.

Cheers,
