A spring and a terminal relate to the technical field of electric connection structures and applied to a grounding connection of a camera inside the terminal, where a fitting component can be inserted into the spring in any side direction and elastically connected to the spring such that a sequence of assembling and disassembling the fitting component can be freely selected. The spring includes a mounting bracket and a contact part that are successively arranged in a first direction, the contact part is coupled to the mounting bracket using at least three elastic limiting arms, and the at least three elastic limiting arms are disposed at an even interval on one end of the contact part proximate the mounting bracket.
