Abstract

The embodiment of the invention discloses a wire connector which comprises a sheath and a first terminal, the sheath is provided with an accommodating cavity, and the accommodating cavity is used for accommodating a contact part of the first terminal and an elastic contact piece. Therefore, the second terminal contact part can be inserted into the first cavity from the third opening, so that the second terminal contact part is electrically connected with the first terminal contact part through the elastic contact piece. Therefore, stable connection between the terminals can be realized, the effective over-current area is increased, the bearing capacity of the wire connector is improved, and connection with a certain included angle between the terminals can be realized.
