Description

Technical Field

[0001] This utility model relates to a terminal and a connector including the terminal. Background Technology

[0002] In existing technology, connectors for connecting enameled wires typically include a housing and terminals disposed within the housing. Each terminal includes a pair of resilient arms. These resilient arms clamp the enameled wire inserted between them to achieve an electrical connection between the enameled wire and the terminal. However, in existing technology, one terminal can only electrically connect one enameled wire. If two enameled wires need to be electrically connected, two terminals are required. This results in a complex connector structure and high cost. Furthermore, in existing technology, the pair of resilient arms of the terminal can only make point contact with a single enameled wire, leading to unstable and unreliable electrical contact, and making poor electrical contact a common problem.
