The invention relates to the technical field of electric meters, especially an electric meter connector assembly. The connector assembly comprises a sleeve body, and a side surface of the sleeve bodyis provided with a bar-shaped port. The sleeve body comprises a first sleeve, a second sleeve, and a connecting ring, and the first and second sleeves are fixedly connected through the connecting ring. Moreover, the thickness of the connecting ring is less than the thickness of the wall of one of the first and second sleeves. An outer side of the connecting ring and the outer sides of the first and second sleeves are located on the same plane. A spring is fixedly connected between the first sleeve and the second sleeve. The upper end of the first sleeve is fixedly provided with an upper end face, and the upper end face is provided with an opening for clamping a binding post, wherein the opening is communicated with the bar-shaped port. The lower end face of the second sleeve is fixedly provided with a lower end face, and the lower end face is provided with a wire hole for clamping a wire, wherein the wire hole is communicated with the bar-shaped port. The melting point of the connecting ring is less than the melting point of the first and second sleeves. The connector assembly can guarantee the stability of a wire core. Moreover, the wire core can be automatically separated with the binding post during fire.
