Abstract

The invention discloses a power splicing fitting with relatively good anti-looseness performance. The power splicing fitting comprises a base body, flat nuts, an axial retainer ring and pressure jaws. The base body is provided with a slide tube, radial guide limiting holes, stopping tables and an annular clamping groove. Each radial guide limiting hole comprises a guide slide hole and an anti-drop slide hole which communicate with each other. Each guide slide hole is arranged on the edge of one side end, far away from the axial retainer ring, of the slide tube of the base body to form a gap. Each pressure jaw is provided with a pressure plate part, a guide slide block part and a drive thread part. The axial retainer ring is clamped and fixed in the annular clamping groove in the outer circumference wall of the slide tube of the base body. The flat nuts are rotationally arranged on the outer circumference wall of the slide tube of the base body. Each flat nut is provided with a flat thread part which is adaptively engaged with the drive thread part of the corresponding pressure jaw. The flat nuts drive the pressure jaws to approach or depart from one another toward the center of the slide tube. The power splicing fitting has a relatively good anti-looseness effect.

Description
