Abstract
The present single-phase converting socket has no fuse, once an electrical device has overload or short circuit, the fuse is fused, and the whole room has no power causing a plurality of inconvenience. The utility model relates to a single-phase converting socket with fuse. The utility model can effectively prevent the power failure situation of the whole room, because of the overload or short circuit of the electrical device. And can convert the sleeve types of the pole numbers and the socket. The utility model is safe and convenient in use.
Description
The utility model relates to a kind of improved single-phase conversion socket, is a kind of single-phase conversion socket that had not only had fuse but also can change number of poles and socket and bush pattern easily, can be widely used in the single-phase electrical equipment apparatus field.
China implements new plugs and sockets national standard on July 1st, 1981, and regulation adopts flat latch and sleeve.But still using cylinder plugs and sleeve also can all not change for the moment among the user at present in a large number, so conversion socket and multipurpose socket arise at the historic moment, existing conversion socket and multipurpose socket are not with fuse, electric equipment one has overload or short circuit, the just fusing of total fuse, full chamber does not have electricity, and inconvenience occurs in and bothers especially evening.
The purpose of this utility model provide a kind of can safe ready ground the sleeve pattern of conversion number of poles and socket, can when overload or short circuit take place electric equipment, can not influence the single-phase conversion socket of the band fuse of All other routes power supply again.
The utility model is realized with following scheme: each inlet wire latch and outlet sleeve are fixed on the insulating base with threaded connector; Except that ground pin and ground connection sleeve.Connect with fuse respectively between other inlet wire latches and the outlet sleeve; Fuse is placed in the space between the insulating base top and the bottom, also fixes with threaded connector; Two groups of outlet sleeves are connected in parallel; Setting up the ground connection sleeve connects with earth electrode with lead; Being connected of insulation cover cap and insulating base, use the threaded connector that pierces into from insulating base to realize.
The embodiment represented below in conjunction with accompanying drawing is described in detail the utility model.
Fig. 1 is that inlet wire is two polar circle latches in the utility model, one group of socket outline drawing that is three extremely flat another groups of sleeve and is two extremely flat sleeves of outlet.
Fig. 2 is the cut-away view of socket shown in Figure 1.
Fig. 3 is the cutaway view of structure shown in Figure 2.
Fig. 4 is that inlet wire is two utmost point flat pins in the utility model, one group of socket outline drawing that is three extremely flat another groups of sleeve and is two utmost point double-purpose sleeves of outlet.
Fig. 5 is the installation diagram of the inlet wire flat pin of socket shown in Figure 4.
Fig. 6 is the cut-away view of socket shown in Figure 4.
Fig. 7 is that inlet wire is three utmost point flat pins in the utility model, and outlet is the socket outline drawing of two group of two utmost point double-purpose sleeve.
Fig. 8 is the cut-away view of socket shown in Figure 7.
Among the embodiment shown in Fig. 1～3, the threaded connector that insulation cover cap 1 and following insulating base 2 usefulness are passed hole 17 is tightened to one; If will take both apart, just this socket must be taken off from circuit, thereby guarantee safety.The copper core 9 of inlet wire cylinder plugs 3, its afterbody car has screw thread, and the stage casing recess is marked with plastics 7, head has coating 8(nickel or chromium).Cylinder plugs 3 is with waist shape packing ring 13, and the latch afterbody passes insulating base 5, with packing ring 11 and nut 12 cylinder plugs 3 and upper base insulating base 5 is tightened to one.Fuse 14 1 ends are pressed on the waist shape packing ring 13 with screw 10, and the other end clamps and with packing ring 15 and nut 4 screw 6 and copper contact pin 21 is anchored on the insulating base 5 with screw 6.Last insulating base 5 relies on four screws 20 and following insulating base 2 to be tightened to one. Sleeve copper sheet 19,22 usefulness screws 23 are anchored on the insulating base 5, and connect with copper contact pin 21.Ground connection sleeve copper sheet 26 usefulness long spiro nails 25 are anchored on the insulating base 5, with nut earth lead are connected with long spiro nail 25 behind plate.Reference column 16,24,18 on the last insulating base 5 plays the role of positioning to ground connection sleeve copper sheet 26, sleeve copper sheet 22,19 respectively.Figure Fig. 2 shows, in this socket except ground connection sleeve part, other part left-right symmetric.
Among the embodiment shown in Fig. 4～6, the threaded connector that insulation cover cap 27 and following insulating base 28 usefulness are passed hole 34 is tightened to one.Inlet wire flat latch 29 is inserted in down in the seam of insulating base 28, its afterbody is square, when four screws of last insulating base 30 usefulness 32 and following insulating base 28 were tightened to one, the square afterbody of latch 29 just in time embedded in the recessed joint of insulating base 30, thereby is fixed.Screw has been attacked at the square afterbody of latch center, screws on a just fixing end of fuse of screw 31; The fixing means of the fuse other end promptly also is anchored on this screw on the insulating base 30 with packing ring and nut with the screws clamp fuse with shown in Figure 3.Structure shown in Figure 6 and similar shown in Figure 2, but sleeve copper sheet 19 is different among the shape of sleeve copper sheet 33 and Fig. 2.
Among the embodiment shown in Fig. 7～8, the threaded connector that insulation cover cap 35 and following insulating base 36 usefulness are passed hole 40 is tightened to one.The fixing means of flat latch 37,38 is same as shown in Figure 5.Flat latch 38 does not connect any electric conductor, and the fixing means of fuse is identical with the method for second embodiment, and sleeve copper sheet 42 dependence threaded connectors are anchored on the insulating base and with fuse and connect, and connect with copper contact pin 41 between the sleeve copper sheet 39 and 42.
The utility model has the advantages that effectively to prevent not having the situation of electricity because electric equipment overload or short circuit cause full chamber, can change again the sleeve pattern of number of poles and socket, safe and convenient to use.
