A connector terminal includes a terminal body. An elastic arm structure is arranged on one end of the terminal body, and includes a support part and a contact part. The support part is a bending structure formed by sequentially connecting multiple extension sections, a first end of the support part is an operation end and a second end of the support part is a connection end, from the connection end to the operation end, an included angle between a first direction and each of extension directions of the multiple extension sections is gradually reduced, and the first direction is parallel to a length direction of the terminal body. The contact part is arranged at the operation end and is bent towards an inner side of the bending structure.
