Summary of the invention
The structure that the purpose of this invention is to provide a kind of combined plug inner frame, after making terminal be interspersed in this perforation, can limit the protruded length of terminal on the one hand at the internal frame body, and the hoop rotation of terminal is restricted, and have a polarization and steadiness, terminal can't be rotated, to meet the safety requirements of appliance plug in the internal frame body.
Above-mentioned purpose of the present invention is achieved in that a kind of structure of combined plug inner frame, and the main body of this internal frame comprises an internal frame body and two-terminal at least, and this internal frame body also is provided with perforation, and described perforation provides the setting of described two-terminal at least, wherein:
Each terminal is provided with an architrave in one section portion, and the peritreme of the perforation of this internal frame body is provided with the limitting casing of a corresponding terminal architrave, it is characterized in that: this architrave exterior contour is " D " font, and this limitting casing corresponds to " D " font, after making terminal be interspersed in this perforation, can limit the protruded length of terminal on the one hand, and the hoop rotation of terminal is restricted, and have a polarization and steadiness at the internal frame body.
The present invention's time purpose is to make the terminal can be under the situation of location, make whole internal frame after combination, no matter in carrying, riveting line, injection molding stowing operation, all can guarantee the protruded length of terminal and internal frame body, and the hoop rotation of terminal is restricted, to meet the requirement of safety standard.
Below in conjunction with accompanying drawing the utility model is elaborated.
