Description

The two poles of the earth function of socket spare

The utility model belongs to a kind of two pole sockets, and what be specifically related to is a kind of two pole sockets that are suitable for the functor form of assembly unit.

The two poles of the earth function of socket spare of tool shutter measure at present all is to be aided with back-moving spring with single shutter to finish the function that the protection terminal does not cover dust, but single shutter requires activity space big, correspondingly requires the volume of functor own to increase, thereby increases cost; In addition, existing socket adopts the mode of connection of binding post and wiring screw more, and this mode easy damaged lead makes wiring insecure.

The purpose of this utility model is to overcome the above the deficiencies in the prior art part, and the two poles of the earth function of socket spare of a kind of compact conformation, dependable performance is provided.

The purpose of this utility model is to realize like this; The utility model is divided into the upper and lower, top comprises the panel and the shutter device of band the two poles of the earth jack, the bottom comprises terminal and base, terminal is positioned at base, the shutter device mainly is made up of shutter and back-moving spring, two block protection doors are to being positioned at the below of panel after piecing together, and under jack, assembly place is formed the gathering sill of similar V-arrangement, to establishing back-moving spring between shutter both sides after piecing together and the panel, when plug inserted jack, plug was imported by gathering sill and passes between two block protection doors, and this moment, two block protection doors were to residing locality yielding separately, when pulling the plug out of the socket, shutter is under the elastic force of back-moving spring and reset; Terminal comprises the socket position copper sheet and the terminal block at the two poles of the earth, wiring screw and pressure-ray film, the terminal block of socket position copper sheet and below is connected as a single entity, the hole that the wiring screw passes terminal block is threaded with the pressure-ray film of terminal block opposite side, being screwed the line screw when establishing screw hole for wiring with wiring screw corresponding section on the base outside base uses, also be provided with plug wire hole on the base, when wiring, lead is inserted between pressure-ray film and the terminal block from plug wire hole, because pressure-ray film and wiring screw adopt and are threaded, so when tightening the wiring screw, pressure-ray film and terminal block compress finishes the wiring action.

The utility model adopts the shutter device of piecing together, and it is little to take up room, and the utlity model has advantage small-sized, compact conformation so make; Adopt the presser type mode of connection of terminal block and pressure-ray film in addition, have the advantage that is difficult for damage wires.

The utility model is described in further detail below in conjunction with drawings and Examples.

Figure 11 is the end view of base among Figure 10.

Figure 12 is the upward view of base among Figure 10.

Extremely shown in Figure 12 as Fig. 1; the utility model is divided into the upper and lower; top comprises panel 1 and shutter device; the two poles of the earth jack 2 that has round jack and flat jack to fuse on the panel 1; the bottom comprises terminal and base 3; terminal is positioned at base 3, and the fastening that panel 1 and base logical 3 crossed buckle and button hole forms an integral body.

As Fig. 1; Fig. 3; Fig. 4; Fig. 5; Fig. 6 and shown in Figure 7; the shutter device comprises a pair of shutter 4 and a pair of back-moving spring 5; a pair of shutter 4 adopts the below of the assembly mode being close to panel 1 by the reinforcement location of the back-moving spring 5 of both sides and panel 1; shutter 4 one sides have the hole of location back-moving spring 5; back-moving spring 5 is compressive state; it is positioned at and assembly place is formed the gathering sill 6 that is similar to V-arrangement under the jack 2 after 4 pairs of assemblies of shutter; after plug inserts jack 2; import and between two block protection doors 4, pass by V-arrangement gathering sill 6; this moment, a pair of shutter 4 was respectively to residing locality yielding separately; when plug was extracted, shutter 4 was by the elastic force of back-moving spring 5 and reset.Gathering sill 6 of the present utility model can be a V-arrangement, and also similar other shape is as long as can make plug successfully be inserted between the two block protection doors 4.

As Fig. 1, Figure 10, Figure 11 and shown in Figure 12, separate by 3 dividing plate on the base between the terminal at the two poles of the earth, terminal comprises the socket position copper sheet 7 and the terminal block 8 at the two poles of the earth, wiring screw 9 and pressure-ray film 10, each socket position copper sheet 7 is inserted the copper sheet riveted by flat slotting copper sheet and circle and is formed, socket position copper sheet 7 parts extend downwards terminal block 8, the hole that wiring screw 9 passes terminal block 8 is threaded with the pressure-ray film 10 of terminal block 8 opposite sides, pressure-ray film 10 is restricted to can not be along threads turn in the base 3, so when tightening or loosen wiring screw 9, pressure-ray film 10 compresses with terminal block 8 or unclamps, outside base 3, twist or loose wiring screw 9 when establishing screw hole 11 for wiring with wiring screw 9 corresponding sections on the base 3, also be provided with plug wire hole 12 on the base 3, present embodiment is established two plug wire holes to make things convenient for wiring at every utmost point, during wiring lead is inserted between pressure-ray film 10 and the terminal block 8 from arbitrary plug wire hole 12, tightens wiring screw 9 then and get final product.
