Abstract

This utility model discloses an inner frame for a plum blossom plug, including an inner frame body. The upper end of the inner frame body is formed with a horizontal fixing rib, a first side anti-retraction rib, a second side anti-retraction rib, and a triangular rib. The horizontal fixing rib, the first side anti-retraction rib, and the second side anti-retraction rib are distributed around the side of the triangular rib. A first fixing adhesive hole is provided at the lower middle part of the first side anti-retraction rib, and a second fixing adhesive hole is provided at the lower middle part of the second side anti-retraction rib. The thickness of the first side anti-retraction rib and the thickness of the second side anti-retraction rib are both 1.2mm. The inner sides of the first fixing adhesive hole and the second fixing adhesive hole are formed with rounded corners with a radius of 0.2mm. The inner frame of the plum blossom plug has increased lateral tensile strength, widened the side structure, increased the strength of the holes and thickened the ribs, and modified the demolding direction of the fixing glue holes. This allows the inner frame to remain in place for 60 seconds when a 75N load is suspended from the side, meeting the requirements for preventing breakage and bending at the end of the wire.
