Accompanying drawing 4 is the utility model plugs and sockets assembling generalized section.

Figure number: 1 elasticity earth terminal, 11 binding posts, 12 thrust mesons, 2 cylindrical cases, 21 shell napex inner edge chamferings, 22 insulation bulge loop end-bevelings, 3 outer shroud terminals, 31 outer shroud binding posts, ring terminal in 4, articulating line terminals in 41,5 aciculiform earth terminals, 6 columns, 61 " bow " shape groove, 7 outer lead-out terminals, 71 outer output contact chips, 72 outer output wiring terminals, 73 outer lead-out terminal internal tooths, lead-out terminal in 8, output contact chip in 81, output wiring terminal in 82, lead-out terminal internal tooth in 83,9 insulation bulge loops, 10 socket centre bores

Be described further below in conjunction with accompanying drawing:

Be made up of plug and the socket that matches, as shown in Figure 1, plug comprises ring terminal 4 in elasticity earth terminal 1, cylindrical case 2, plug outer shroud terminal 3 and the plug; Socket comprises lead-out terminal 8 in aciculiform earth terminal 5, column 6, the outer lead-out terminal 7 of socket, the socket.

Figure 2 shows that the plug construction schematic diagram, be provided with insulation bulge loop 9 in the cylindrical case 2, insulation bulge loop 9 is a cylindrical body, inner and outer rings terminal (4,3) is arranged at the interior outside of insulation bulge loop 9 respectively, and a binding post (41 is respectively arranged, 31), inner and outer rings terminal (4,3) becomes one with insulation bulge loop 9 and cylindrical case 2 injection mouldings, also can be removable single separate piece.Elasticity earth terminal 1 is the bending shape, places the bottom of cylindrical case 2, and is provided with binding post 11 and thrust meson 12, and the end is a contact chip, and stretches out from cylindrical case 2 bottom centre holes; The end of cylindrical case 2 top inner edges and insulation bulge loop 9 is respectively equipped with chamfering (21,22), and chamfering is rounded.

Figure 3 shows that the socket schematic diagram, comprise the column 6, aciculiform earth terminal 5 and the inside and outside lead-out terminal (8,7) that are provided with " bow " shape groove 61, aciculiform earth terminal 5 places the top of column 6 centre bores 10; In, outer lead-out terminal (8,7) be the metal anchor ring, place the bottom of two inverted groove of " bow " shape groove 61 respectively, extend a plurality of elastic contact chips (71 on the metal anchor ring, 81), it is exported contact chip 71 at home and abroad and passes groove from a side of groove and stretch out to the groove inner edge, and interior output contact chip 81 passes groove from the opposite side of groove and stretches out to inner edge, " bow " shape groove 61 on the column 6 is meshed with the insulation bulge loop 9 of cylindrical case 2, contact chip (81,71) with in, outer shroud terminal (4,3) coincide and joins, because in, outer shroud terminal (4,3) be ring-type, so contact is reliable, contact area is big, can pass through big electric current, be difficult for producing electric arc.The inside and outside output wiring terminal (82,72) that downward extension is arranged on the metal anchor ring; A plurality of internal tooths (83,73) (see figure 1) is also respectively arranged on the inside and outside lead-out terminal of socket (8,7), inside and outside lead-out terminal (8,7) can firmly be buckled on the column 6.

Figure 4 shows that plugs and sockets assembling schematic diagram, the elasticity earth terminal 1 of plug is an elastic contact chip, can be during use than the contact earlier of other terminal, and the back disconnects, and is safe in utilization.

The utility model has following advantage:

1. owing to be that wireless connection can make base, power line separate with housing, easy to use, Fast, safety.
