Embodiment 2：
As shown in FIG. 13 to 15, the present embodiment with respect to embodiment 1 difference lies in：Zero curve sleeve is equipped with and firewire sleeve
Identical safety switch assembly 1, it is separately positioned there are gap between zero curve fishplate bar 50 and zero curve slot set 52, for controlling connection zero
The safety switch assembly 1 of line fishplate bar 50 and zero curve slot set 52 is set at gap 51, the first wire connection terminal of safety switch assembly 1
10 and second wire connection terminal 11 respectively with zero curve slot set 52 and zero curve fishplate bar 50 connect.
The function of safety switch assembly 1 on zero curve sleeve is identical with 1 function of safety switch assembly on firewire sleeve.Cause
For in daily life, the firewire and zero curve of socket may there are a misconnections, i.e. zero curve and firewire to connect during connecing
Instead.
Insert row in the market, with plug, and plug is mostly three prongs of plug, and reason is that three prongs of plug can ensure to insert
Zero curve firewire is corresponding in row, because the direction of insertion of three prongs of plug is fixed-direction, double insert can then exchange mutually.
But part manufacturer can produce double slotting plugs according to actual demand, if the present invention is applied to insert row when tools,
When the plug of insert row is double inserts, double plugs are not easy to distinguish zero curve and firewire when in use, if the insertion side of double plugs
To reversed, then high-voltage electricity is connected in zero curve sleeve, and firewire sleeve then no power, it is equivalent to zero curve firewire and exchanges.
Therefore the advantage of this embodiment is that, after zero curve firewire is exchanged, it can still give play to what is mentioned in embodiment 1
Function, safety higher.
The above makes the preferred embodiment of the present invention, does not depart from this hair for those of ordinary skill in the art
Under the premise of bright principle, several variations and modifications can also be made, these also should be regarded as protection scope of the present invention.
