The purpose of this utility model provides a kind of terminal formula safety plug, and its unexpected generation that can not cause getting an electric shock can be improved the fail safe of use greatly, and the outstanding phase is the effect that has more protection at old man or children.

For achieving the above object, the utility model is taked following design:

A kind of terminal formula safety plug, it is provided with an insulating body, and its front end is formed with an inserted terminal, and this insulating body inside is provided with most terminal accommodation holes, and this terminal accommodation holes front end respectively is connected with a spliced eye; Most conducting terminals are arranged, it respectively is contained in the terminal accommodation holes of this insulating body, and these conducting terminals are built-in, and this conducting terminal is provided with the fixing body that protrudes from outer wall, this fixing body is the terminal accommodation holes inwall of clip in insulating body, and this conducting terminal front end is formed with a Plug Division.

The utility model is to form multipole separation shape by most conducting terminals, constitute a kind of multi-pole plug, this conducting terminal is adopted built-in design, metallic conductor can not exposed, therefore even the user holds plug accidentally and misplugs socket aperture in general family expenses, the unexpected generation that also can not cause getting an electric shock can significantly be improved the fail safe of use, and the outstanding phase is the effect that has more protection at old man or children.

The utility model is described in further detail below in conjunction with accompanying drawing

Referring to Fig. 4, Fig. 5, shown in Figure 6, a kind of terminal formula safety plug, it is made up of an insulating body 10 and most conducting terminals 11, wherein insulating body 10 is to make with engineering plastic, its hardness and metal are suitable, this insulating body 10 is to be a cuboid, these insulating body 10 front ends also are formed with an inserted terminal 12, can be in order to plug with the socket that docks, these insulating body 10 inside longitudinally are provided with most terminal accommodation holes 13, the insulating body 10 of present embodiment is to be provided with two terminal accommodation holes 13, so that collocation is provided with two conducting terminals 11, in order to constitute a kind of two utmost point safety plug structures, this terminal accommodation holes 13 is to be not isometrical circular hole roughly corresponding with conducting terminal 11 profiles, these terminal accommodation holes 13 front ends respectively are connected with a spliced eye 14, can insert for the terminal of the socket that docks.

Conducting terminal 11 is made with steel, these conducting terminals 11 respectively are contained in the terminal accommodation holes 13 of insulating body 10, this conducting terminal 11 roughly is an O type hollow tube, offer an elongated slot 15 on this conducting terminal 11 vertically, these conducting terminal 11 nearly back-end locations are provided with the two fixing bodies 16 that protrude from outer wall, this two fixings body 16 can embed terminal accommodation holes 13 inwalls of clip in insulating body 10, make conducting terminal 11 be able to firm the combination with insulating body 10, conducting terminal 11 nearly back-end location punching presses form one and protrude from inner retaining film 17, this retaining film 17 can be in order to confined bed electric terminal 11 rear ends, prevent when making encapsulating that glue from infiltrating plug inside, these conducting terminal 11 front ends form the Plug Division 18 of a bell mouth shape, this Plug Division 18 is the spliced eyes 14 corresponding to insulating body 10, can peg graft for the terminal of the socket that docks, these conducting terminal 11 rear ends stretch out in insulator basis 10, can be for being welded to connect with lead 19 (as shown in Figure 7), then can carry out encapsulating in this conducting terminal 11 and insulating body 10 rear ends and make and form a lining body 20.

As Fig. 8, shown in Figure 9, this lining body 20 also can compound mode be socketed on this conducting terminal 11 and insulating body 10 rear ends, and can be provided with sizing material 21 in this conducting terminal 11 and insulating body 10 rear ends and sealed; Form a kind of terminal formula safety plug structure by above-mentioned.

As Figure 10, shown in Figure 11, the insulating body 10 of present embodiment is to be provided with three terminal accommodation holes 13, and the collocation three conducting terminals 11 are set, in order to constitute a kind of three utmost point safety plug structures.
