Metal stay wire connector and metal stay wire assembly

The utility model provides a metal stay wire connector and a metal stay wire assembly. The metal stay wire connector comprises a connector body. The connector body is hollow to form a cavity. The cavity is convex, and a movable stay wire slot matched with the connection portion of the end portion of a metal stay wire is formed in the end portion of the cavity. The inner diameter of the movable stay wire slot is greater than the outer diameter of the connection portion so that the connection portion can rotate freely relative to the connector body when clamped in the movable stay wire slot. One side wall of the cavity of the connector body is provided with an open slot communicated with the cavity. The width of the open slot is not smaller than the axial length of the connection portion so that the connection portion of the metal stay wire can be plugged into the cavity from the open slot. A locating tongue deeply extending into the cavity is arranged in the cavity. The locating tongue is matched with the movable stay wire slot in position so that a space allowing the connection portion to rotate in a limited mode can be formed between the movable stay wire slot and the locating tongue. The distance between the locating tongue and the cavity is smaller than the external diameter of the connection portion.
