Abstract
The invention discloses a split clamp fitting. Two terminal clamping plates used for oppositely clamping a terminal plate are arranged on a terminal interface of the clamp fitting. The two terminal clamping plates are conductively connected with a wire interface. The opposite lateral plate surfaces of the two terminal clamping plates are provided with conductive contact surfaces which are used for fitting the two lateral plate surfaces of the terminal plate respectively. The two terminal clamping plates are correspondingly provided with fastening holes extending in relative directions. Thus, when the fitting is electrically connected with the terminal plate, the terminal plate is clamped between the two terminal clamping plates, and a diversion function is achieved through wire contact between the conductive contact surfaces on the opposite lateral plate surfaces of the two terminal clamping plates and the two lateral plate surfaces of the terminal plate. Therefore, when bolt connection between the fitting and the terminal plate is loosened, there is always one of the terminal clamping plates closely fitting the terminal plate. The clamp fitting is always in close contact with the terminal plate, the area of conductive contact is increased through conductive contact between the two terminal clamping plates and the terminal plate, and the through-flow performance is further improved.
