Abstract
The invention discloses a three-pin detachable plug. A wire-clamping support is disposed in a plug housing. The front end of the wire-clamping support is fixedly connected with the center of the inner surface of a bottom casing. A wire trough is lengthways disposed on the surface of the wire-clamping support in a way of getting closer to a side than the other side. One end of the wire trough extends to the front end of the wire-clamping support and is in an opening shape. The other end of the wire trough extends to the rear end of the wire-clamping support and is in a triangular opening shape. Wire-clamping teeth are uniformly distributed on a sidewall of the wire trough. An inclined surface is formed on a position, close to the triangular opening, on the other sidewall of the wire trough. A wire-clamping sliding block is disposed on the triangular opening on the other end of the wire trough. The three-pin detachable plug is ingenious in overall design. The triangular wire-clamping sliding block is used for fixing wires and achieves a stable fastening effect. Ribs distributed transversely and lengthways are used for naturally separating the wires so as to effectively prevent short circuit between the wires and prevent accidents, thereby further improving product security.
