[0002] The present invention relates to a terminal body, a terminal including the terminal body, and a connector including the terminal. [Background technology]

[0003] In the prior art, high-voltage connectors typically include a housing and a terminal mounted in the housing. The terminal includes a terminal body, a pair of contacts mounted in a mating portion of the terminal body, and a locking member mounted at the end of the mating portion of the terminal body to lock the terminal to the housing. The pair of contacts are used for electrical contact with a mating terminal, and the crimping portion of the terminal body is adapted to be crimped onto the conductor core of a cable. In this way, an electrical connection can be established between the cable and the mating terminal via the terminal of the connector.
