Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] The shell-type safety plug is composed of a pressure column 1, a protective shell 2, a pull ring 3, a plug body 4, a wire 5, a rod hole 6, a metal insert 7, an insert groove 8 and a spring 9.

[0014] The protective shell 2 is a box made of transparent plexiglass, and the plug body 4 with the metal insert 7 is located in the protective shell 2 and has a dynamic cooperation relationship with the protective shell 2 in the vertical direction. There is a circular rod hole 6 with two gaps in the center of the upper surface of the protective case 2 . The two gaps are both rectangular and distributed at both ends of the edge of the rod hole 6 along the diameter direction of the rod hole 6 .

[0015] The pressure column 1 connected to the plug body 4 protrudes from the rod hole 6 . The pressure column 1 is cylindrical and has a dynamic fit relationship ...

Abstract

The invention relates to a plug, in particular to a housing type safety plug. The housing type safety plug consists of a pressure column, a protective shell, a draw ring, a plug body, a wire, a rod hole, a metallic inserting piece, an inserting piece slot and a spring, wherein the protective shell is a box body made of transparent organic glass; the plug body is arranged in the protective shell and has a movable fit relationship with the protective shell in the vertical direction; the center of the upper surface of the protective shell is provided with the round rod hole provided with two notches, the two notches are both rectangular and arranged at both ends of the edge of the rod hole along the diameter direction of the rod hole; the pressure column connected with the plug body is extended out of the rod hole; and the pressure column is cylindrical and has a movable fit relationship with the rod hole. When the plug is plugged in or out, the metallic inserting piece is not exposed, so that the probability of getting an electric shock is eliminated.

Description

technical field [0001] The invention relates to a plug, in particular to a shell type safety plug. Background technique [0002] In the existing ordinary electrical plug, when the metal insert is inserted into the socket, the process from the metal insert to the socket is a process of live exposure. If the user's finger accidentally touches the metal insert during this process, it will Electric shock accidents may occur. This is a potential danger for children who have no common sense of safe electricity use. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a shell-type safety plug capable of preventing electric shock during the process of inserting an electrical plug. [0004] The solution to the technical problem of the present invention is: the sheath type safety plug is composed of a pressure column, a protective shell, a pull ring, a plug body, a lead wire, a rod hole, a metal insert, an insert gr...
