Abstract

The invention relates to a plug inside frame. The plug inside frame comprises an inside frame shell and metal pins, wherein the inside frame shell is provided with sockets, the back surface of each socket is provided with a protruded piece, each protruded piece is rotationally connected to one socket, and the inner wall of each protruded piece is provided with two limiting protrusions; each limiting protrusion is in an inverted isosceles trapezoid shape, the thickness of the upper end of each limiting protrusion is 1.1mm, and the thickness of the lower end of each limiting protrusion is 0.7mm; each metal pin is provided with two positioning holes, and the shapes of the positioning holes are matched with those of the limiting protrusions. The heights of the metal pins are limited by stirring the protruded pieces to enable the limiting protrusions to be matched with the positioning holes, and the heights of terminal pins can be limited better.

Description

technical field [0001] The invention relates to a power supply connection line that can be plugged together, and belongs to the field of power supply connection lines for electrical equipment. Background technique [0002] The plug structure is an important part to connect the power supply and electrical appliances, and to ensure the safe and stable use of electrical appliances. In the existing power plug, the inner frame of the power plug is used to fix the power contact sheet, but the internal structure of the existing plug is too simple, and the pin height of the plug is stipulated by the standard, but most of the plug manufacturers currently have a The height is limited by the injection mold, but during the injection molding process, due to the injection pressure and other reasons, the limit will not work, and it is easy to cause the height of the plug pins to be different. Contents of the invention [0003] The technical problem to be solved by the present invention ...
