At first with reference to figure 3, this illustrates and will be installed in the inner surface of a moulded parts 2 of (socket) header board back of general type shown in Figure 1 in using.This moulded parts comprises on the whole the structures by 4 and 6 expressions, the installed part separately 8 and 10 with the operating parts of the rocker switch assemblies of reference number 12 and 14 expressions of being used for usually respectively that this structure provides the supply socket of band shutter and is positioned at each socket top.

As shown in the figure, this moulded parts comprises that the recess 16 and 18 and of live wire that the mode side by side with traditional that is used for admitting attaching plug is arranged and (property) line pin is used for the respective recess 20 of earth pin.

The top of each socket is one to be used for the recess of the switching mechanism that comprises the metal plug-in strip of a general known type, and this metal plug-in strip does not specifically illustrate, but it is suitable for being activated by a plunger 22 that is installed on the rocking arm 24.

Each rocking arm has all that a pair of interval separates is suitable for the protuberance 26 and 28 that the coupling recess on the rear surface with the header board of jack assemblies cooperates, and operating parts 14 is installed in the end of rocking arm, so that pass through the top or the bottom of pressing operation spare 14 front surfaces, and this mechanism is switched between the position of the switch that switches on and off in common mode.The medial extremity of each rocking arm 24 is arranged in a medial cradle element 30 that is shaped suitably (only can see the medial cradle element that is used for left side rocking arm 24 from Fig. 3), so that under confined state as shown in the figure, the medial cradle 30 that rocking arm and operating parts can be by being positioned at the assembly inner end and along two protuberances 26 of rocking arm length and 28 and accurate location.

The leftmost side and the rightmost side at housing also are respectively arranged with a corresponding outrigger 32, and this setting is such, i.e. rocking arm 24 or be positioned at position as shown in Figure 3 in assembling process with the state that its operating parts 14 or 12 is in the most close assembly central authorities, perhaps by around the position of actuating plunger 22 Rotate 180 ° and actual optional " mirror image " position that arrives, each operating parts 12 or 14 is positioned at the outside of plunger 22 in this position.Fig. 4 illustrates this corresponding layout, and wherein, two rocking arms 24 have been installed in the housing, so that operating parts 12 and 14 is positioned at " outside " position.This protuberance and recess will be appreciated that rocking arm protuberance 26 is symmetrical arranged with their the same position with respect to plunger 22 of the cooperating recesses that is arranged in the header board rear surface with 28, so that still can cooperate in an identical manner.In addition, as shown in Figure 5, also a rocking arm 24 can be set to its operating parts 12 and be positioned at " inboard " position, another rocking arm is set to its operating parts 14 and is positioned at " outside " position simultaneously.

Certainly, can recognize clearly also, can construct one and only comprise Fig. 3 that same permission of this supply socket is arranged on its left side or right side with switch operator to the left side of moulded parts shown in Figure 5 or the single head supply socket of right-hand part by accompanying drawing.

In the embodiment of Fig. 3 to 5, the shutter 34 of three-phase socket is a common known type, wherein, the insertion of earth pin make shutter in a pair of guiding channel 36, overcome one be installed in the center the spring (not shown) effect and upwards slide. this moves up the wing 38 of shutter, yet so that open the hole that is used for plug live wire and neutral pin., also be formed with on the housing guiding groove to 40 with complicated shutter mechanism in conjunction with a type shown in Figure 6. this is that design is used for forming interlocking between the Rocker arm 44 that opens and closes a device 42 and an optional form, if just do not take off socket so that the user cuts off the electricity supply earlier, mains switch will automatically return to " disconnection " position. similarly, opening power again is unless inserted a plug.

This structure is worked in the following manner: except the routine " wing " 38 of the jack that is used to close live wire and neutral pin, the frame structure 46 that this shutter also comprises on each side direction of shutter and stretches out and cooperate with a guiding groove 40 and an independent interlocking part 48, this interlocking part 48 is suitable for engaging below the lower limb of the respective end of rocker member 44.

From accompanying drawing as can be known, the Rocker arm 44 of the embodiment of Fig. 6 rocking arm 24 extremely more embodiment illustrated in fig. 5 than Fig. 3 is much longer, so that the one end is engaged in each

end frame element

30 and 32 interactional with it, and is " turnover " unlike rocking arm 24.In order to make operating parts can be installed in " inboard " or " outside " position, each end of Rocker arm 44 is provided with a pair of

wing

50,52 that extends up and down.One has in its rear surface downwards and the operating parts (not shown) of upwardly extending cooperation passage can slide on this wing from " inboard ", activates the position so that be located at one on the desired end of Rocker arm 44.Should be appreciated that in use, behind complete socket of assembling, can operating parts be located in position effectively by the hole of a respective shapes in the header board.

The structure 46 that stretches out of shutter all is configured to cooperate with an interlocking part 48, and this interlocking part 48 engages with operating parts 12 or 14, so that when inserting a plug, promptly as described in detail later when interlocking part 48 is in disengaged position operating parts can only move to on-position.When removing plug, shutter mechanism moves down under the load of its spring, also is returned to " disconnection " position by spring-loaded Rocker arm 44 and the corresponding sports of interlocking part 48 is feasible.

And, the same with embodiment among Fig. 3 to Fig. 5, be understandable that this structure also can provide a single head socket that comprises at the mutual interlocking gear of an optional operating parts and between shutter and this operating parts of its either side.Because the symmetrical structure of Rocker arm 44, mutual interlocking gear are especially reliable and be not easy to be stuck because be applied to slide and rotatable parts on operating physical force with respect to the center line of socket and switching mechanism 54 complete equipilibriums of center installation correspondingly.

Fig. 7 to Figure 11 has described the operation of switch contact and mutual interlocking gear in greater detail.

Fig. 7 is illustrated in the switching mechanism of " connection " position, wherein, when Rocker arm 44 makes plunger 22 move to its turned position, top, makes movable contact 51 contact fixed contacts 53 by traditional central role (overcentre action) of crossing.Similarly, when in opposite direction the motion of plunger 22 by rocking arm moved to turned position, its underpart, movable contact 51 broke away from fixed contacts, thereby makes switch " disconnection ", as shown in Figure 8.

Fig. 9 illustrates and is in " disconnection " state, the i.e. position of the mutual interlocking gear of shutter closed condition.The upper end of shutter frame 46 has an extension 55 that increases, and this extension forms the abutment of a protuberance 56 on the interlocking part 48 below shutter is in the time.This stops the lower end of operating parts 12 to be moved to " connection " position.

When shutter slided into the position that makes progress shown in Figure 10, on the other hand, along with the insertion of attaching plug, the recess 58 in the extension of shutter frame was aimed at protuberance 56, makes this extension no longer stop moving of interlocking part.This permission operating parts 12 moves to " connection " position as shown in figure 11.

Also obviously visiblely from Figure 11 be, when pulling the plug out of the socket from socket subsequently, switch will automatically return to " disconnections " position, can provide an inclined cam surface 60 when shutter 46 outside promotion protuberance 56 during to lower slider because recess 58 is configured as.
