Referring to fig. 2, the switch assembly 1 may include a switch housing 11, a button 12, and a conductive member 13, wherein the switch housing 11 is located corresponding to the location of the mounting hole 01, the switch housing 11 has an inner cavity, and a portion of the button 12 is located in the inner cavity of the switch housing 11 and another portion is located outside the switch housing 11; a conductive element 13 is located in the interior cavity of the switch housing 11 and contacts a portion of the button 12 to receive actuation of the button 12.

The connection bar is a conductive medium for connecting the power supply circuit of the power source and the plug bush, and in the related art, the connection bar and the plug bush are generally of an integrated structure, and are directly assembled in the socket housing and welded with the switch assembly through the jumper wire. However, in the present embodiment, the connector strip 2 and the insert 3 may be of two separate structures, between which a controlled electrical connection may be made via the conductive element 13.

As shown in fig. 2, in the embodiment of the present application, the connection bar 2 includes a main body portion 21 and at least one branch portion 22, the main body portion 21 is connected to the at least one branch portion 22, and the branch portion 22 is configured to be disposed corresponding to the conductive element 13, so that the conductive element 13 is respectively in contact with and separated from the branch portion 22 in two adjacent actuations of the button 12. The main body 21 and the branch 22 of the connecting strip 2 may be located on different planes, for example, the plane where the main body 21 is located may be perpendicular to the plane where the branch 22 is located.

With continued reference to fig. 2, the sleeve 3 includes a sleeve portion 31 and an extension portion 32. The position of the plug bush part 31 corresponds to the position of the plug hole 02 on the socket shell 0, when the power input end of the electric equipment is plugged in the plug hole 02, the wiring terminal of the power input end of the electric equipment is connected with the plug bush part 31 substantially, and therefore electric energy transmission is achieved; the extension 32 is connected at its head end to the socket portion 31 and at its end to the conductive element 13.

As shown in fig. 3A and 3B, in some embodiments of the present application, the conducting element 13 may be a rocker 132, a middle portion of the rocker 132 is engaged with the extension 32 of the socket 3, and a first end 130 of the rocker 132 corresponds to the branch 22.

Fig. 3A and 3B illustrate one possible button configuration when the conductive element 13 is a rocker 132. As shown in fig. 3A and 3B, the button 12 includes a button body 121, an elastic device 122, and a spool 123. One end of the elastic device 122 is connected to the button body 121, and the other end is connected to the sliding column 123, and one end of the sliding column 123 far from the elastic device 122 is in contact with the conductive element 13. When the button 12 is pressed by an external force, the rocker 132 can be actuated by the sliding column 123 to move, so that the rocker 132 and the connecting bar 2 are switched between a contact state and a separation state. Illustratively, the elastic means 122 may be a compression spring.

In this case, the first end 130 of the rocker 132 can be actuated to tilt or fall by pressing the button 12, and when the first end 130 of the rocker 132 tilts, the rocker 132 separates from the extension 32 of the plug bush, and the power supply circuit is disconnected; when the first end 130 of the rocker 132 falls, the rocker 132 contacts the extension 32 of the plug bush, and the power supply circuit is conducted.

As shown in fig. 4, two sides of the rocker 132 have first clipping structures 1322, the end of the extension 32 has a second clipping structure 321, and the second clipping structure 321 is engaged with the first clipping structure 1322, so that the rocker 132 swings with the end of the extension 32 as a fulcrum.

For example, the rocker 132 may include a rocker body 1321 and two wing plates, the two wing plates are respectively located at two sides of the rocker body 1321, each wing plate is provided with a first limiting groove (i.e. a first clamping structure 1322), and a groove width of the second limiting groove is slightly larger than the thickness of the extension 32 of the plug bush 3. The end of the extension 32 of the plug bush 3 may have a second limiting groove (i.e. the second clamping structure 321), the rocker main body 1321 is located in the second limiting groove, and two side walls of the second limiting groove are respectively located in the first limiting grooves of the two wing plates of the rocker 132 for limiting, so that the rocker 132 and the extension 32 of the plug bush 3 are kept in relatively stable connection, and the rocker 132 is unlikely to fall from the first limiting groove.

As shown in fig. 5A and 5B, in some embodiments of the present application, the conducting element 13 may be a cantilever beam 131, a first end 130 of the cantilever beam 131 corresponds to the branch portion 22, and an end opposite to the first end 130 is clamped or bolted to the extension portion 32 of the socket 3. In fig. 5A and 5B, the cantilever beam 131 is connected to the extension 32 of the socket 3 by a screw.

When the conducting element 13 is a cantilever beam 131, the structure of the button 12 may be, for example, a self-locking button, the button 12 moves downward upon one press, the lower portion of the button 12 applies a force to the first end 130 of the cantilever beam 131 to make it contact with the corresponding branch 22, and the lower portion of the button 12 maintains the current position; when the button 12 is moved upward at the next pressing, the lower portion of the button 12 releases the pressure on the first end 130 of the cantilever beam 131, and the first end 130 of the cantilever beam is automatically lifted up by its own elasticity to be separated from the corresponding branch portion 22.

In this case, the first end 130 of the cantilever beam 131 can be actuated to remain in the natural state or be depressed by pressing the button 12, when the first end 130 of the cantilever beam 131 remains in the natural state, the cantilever beam 131 is separated from the extension 32 of the socket 3 and the power supply circuit is disconnected; when the first end 130 of the cantilever beam 131 is pressed, the cantilever beam 131 contacts the extension 32 of the socket 3, and the power supply circuit is conducted.

In the present embodiment, as shown in fig. 6 and 7, the branch portion 22 of the connection bar 2 and the extension portion 32 of the socket 3 may both extend into the inner cavity of the switch housing 11.

When assembling the connecting bar 2, the branch portion 22 of the connecting bar 2 may be aligned with the position of the first opening 111, and then the connecting bar 2 may be moved toward the set direction, so that the branch portion 22 may enter the first opening 111 and the body portion 21 may enter the stopper slit 1131.

As shown in fig. 8, when the switch socket has a plurality of switch assemblies 1, the switch assemblies 1 may be sequentially arranged along the extending direction of the limiting gap 1131, accordingly, the number of the branch portions 22 on the connecting strip 2 may be multiple, each branch portion 22 corresponds to one switch assembly 1, and the same main body portion 21 sequentially passes through the limiting gaps 1131 of the switch housings 11 to be clamped and fixed, so that the space in the socket housing 0 is reasonably utilized, the material is saved, and the assembly process is simplified.

For example, the lightening holes may be opened on the bottom wall of the switch case 11 and the cover plate 141 of the switch cover 14.

As shown in fig. 10, in some implementations of the embodiment of the present application, the switch housing 11 has a supporting column 143 on the inner side, the position of the supporting column 143 corresponds to the position of the first opening 111, and when the switch cover 14 is connected to the switch housing 11, the supporting column 143 is located in the switch housing 11 through the first opening 111 to support the branch portion 22 of the connecting bar 2, so as to prevent the branch portion 22 from being deformed or broken under the pressing of the conductive element 13.

In some embodiments, the switch housing 11 has two branches 22 of the connecting bar 2 therein, and the inside of the switch cover 14 may have two support columns 143, each support column 143 being used to support one branch 22.

As shown in fig. 11, in some implementations of the embodiment of the present application, there are two connection bars 2 and two insertion sleeves 3, and the two connection bars 2 are respectively located at two opposite sides of the switch housing 11; the extending parts 32 of the two plug bushes 3 are located on the same side of the switch shell 11, and the two plug bushes 3 correspond to the two connecting bars 2 respectively.

The structure of the switch socket provided by the embodiment of the present application can be applied to both a single-break switch socket and a double-break switch socket, and the following description takes the conduction element 13 as the rocker 132 as an example:

as shown in fig. 12A, when the switch socket is a single-break switch socket, there is only one rocker 132 in the switch assembly 1, the rocker 132 is connected to the end of the extension 32 of one plug 3, and the rocker 132 is switched between the contact state and the separation state with the branch portion 22 of one connecting bar 2 under the actuation of the button 12, and the connecting bar 2 is connected to the live wire of the power supply circuit. The other connecting strip 2 and the other plug bush 3 are connected by a conductor 4 or directly to be kept in a normal open state, and the connecting strip 2 is connected with the zero line of a power supply circuit. The conductor 4 may be, for example, a planar metal sheet.

As shown in fig. 12B, in the case of a double break switch socket, the switch assembly 1 includes two seesaws 132, and the two seesaws 132 are connected to the distal ends of the extensions 32 of the one insert 3, respectively. The button 12 comprises two elastic means 122 and two sliding columns 123, the two sliding columns 123 being in contact with two rockers 132, respectively, and the two rockers 132 can be actuated simultaneously each time the button 12 is pressed. Upon actuation of the button 12, the two rocker arms 132 are switched in a contact state and in a disconnection state with the branches 22 of the two connecting strips 2, respectively, while the two connecting strips 2 are connected with the live and neutral wires of the mains supply circuit, respectively.

When the branch portions 22 of the two connection bars 2 are simultaneously located in the switch case 11, the two connection bars 2 are easily brought into contact to cause a short circuit due to a limited space inside the switch case 11. To solve this problem, as shown in fig. 13, in some implementations of the embodiments of the present application, the switch housing 11 has a partition 115 therein, and a portion of the extension 32 of one plug bush 3 extending into the switch housing 11 and a portion of the corresponding branch portion 22 of the connecting bar 2 extending into the switch housing 11 are located on one side of the partition 115; the part of the extension 32 of the other plug bush 3 extending into the switch housing 11 and the corresponding part of the branch 22 of the connecting bar 2 extending into the switch housing 11 are located on the other side of the partition 115. Therefore, the two plug bushes 3 and the two connecting strips 2 cannot be contacted with each other, and the safety of the switch socket is improved.

As shown in fig. 1, in some embodiments of the present application, the switching receptacle further comprises an overload protector 05, and the overload protector 05 is also mounted in the receptacle housing 0, and has one end connected to the switching assembly 1 and the other end connected to the live wire, for automatically repositioning (or automatically springing up) the button 12 to disconnect the power supply circuit when the load on the switching receptacle is excessive.

The operation principle of the switch socket provided by the embodiment of the present application is described below with reference to fig. 1, 3A, 3B, 14 and 15.

Referring to fig. 1, the switch socket provided by the embodiment of the present application has four sets of jacks 02, and each set of jacks 02 is on-off controlled by one switch assembly 1.

Fig. 14 shows a control circuit diagram of a single-break switch socket, wherein K1-K4 correspond to four switch assemblies 1 respectively. It can be seen that each switching assembly 1 is connected to the live line (L), and the live line of the power supply circuit is switched on after the switching assemblies 1 are engaged; after the switching assembly 1 is opened, the supply circuit is opened.

Fig. 15 shows a control circuit diagram of a double-break switch socket, wherein K1-K4 correspond to four switch assemblies 1 respectively. It can be seen that each switch assembly 1 is connected to the live line (L) and the zero line (N) at the same time, and after the switch assemblies 1 are jointed, the live line and the zero line of the power supply circuit are both conducted; after the switch assembly 1 is disconnected, the live wire and the zero wire of the power supply circuit are disconnected. Compared with a single-break switch, the double-break switch socket has better safety.

The operating principle of the switch assembly 1 is as follows:

as shown in fig. 3A, when the front sliding column 123 contacts with the side of the rocker 132 far from the first end 130, so that the first end 130 of the rocker 132 is tilted, the rocker 132 is separated from the branch portion 22 of the connecting bar 2, and the power supply circuit is broken. When the button body 121 is pressed in this state, the sliding column 123 moves in a direction to approach the first end 130 of the rocker 132, so that the first end 130 of the rocker 132 gradually approaches the branch portion 22 of the connecting bar 2, until the state shown in fig. 3B is reached, and the first end 130 of the rocker 132 is in contact with the branch portion 22 of the connecting bar 2, and the power supply circuit is a path.

When the button body 121 is pressed in the state shown in fig. 3B, the sliding column 123 moves in a direction away from the first end 130 of the rocker 132, so that the first end 130 of the rocker 132 tilts again and is away from the branch portion 22 of the connecting bar 2, until the state shown in fig. 3A is reached, the first end 130 of the rocker 132 and the branch portion 22 of the connecting bar 2 are in a separated state, and at this time, the power supply circuit is once again disconnected.
