Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0028] like Figures 1 to 8 As shown, an embodiment of the utility model is provided, the extension socket comprises a base 1 and an inner panel 2 and an outer panel 3 mounted on the base 1, a copper strip assembly is provided between the base 1 and the inner panel 2, the copper strip assembly comprises a live copper strip 4, a neutral copper strip 5 and a ground copper strip 6, a first live terminal 7 electrically connected to the live copper strip 4, a first neutral terminal 8 electrically connected to the neutral copper strip 5 and a first ground terminal 9 electrically connected to the ground copper strip 6 are also provided between the base 1 and the inner panel 2, the first live terminal 7, the first The neutral wire terminal 8 and the first ground wire terminal 9 are both located on the same side of the copper strip assembly. A second live wire terminal 10 electrically connected to the live wire copper strip 4, a second neutral wire terminal 11 electrically connected to the neutral wire copper strip 5, and a second ground wire terminal 12 electrically connected to the ground wire copper strip 6 are also provided between the base 1 and the inner panel 2. The second live wire terminal 10, the second neutral wire terminal 11 and the second ground wire terminal 12 are respectively arranged on both sides of the copper strip assembly with the first live wire terminal 7, the first neutral wire terminal 8 and the first ground wire terminal 9.

[0029] The beneficial effects of such a configuration are as follows: the utility model has two groups of terminal parts that can be electrically connected to the wires in the dark box, and the two groups of terminal parts are respectively located on both sides of the copper strip assembly. This structure allows both sides of the extension socket to be wired, and the extension socket can be installed on the dark box in either the left or right direction without blocking the adjacent original socket. It has the advantages of easy installation and better practicality.

[0030] In this embodiment, the second live wire terminal 10, the second neutral wire terminal 11 and the second ground wire terminal 12 are symmetrically arranged on both sides of the copper strip assembly with the first live wire terminal 7, the first neutral wire terminal 8 and the first ground wire terminal 9 respectively, which has the advantage of being more beautiful.

[0031] It is further provided that a wiring hole 13 is respectively opened on the base 1 at positions corresponding to both sides of the copper strip assembly, and a baffle 14 is provided in each wiring hole 13 . The baffle 14 is connected to the base 1 via at least one connecting strip 15 on all sides.

[0032] The beneficial effects of such a setting are as follows: the wiring holes facilitate the wires of the dark box to extend into the extension socket and connect with the terminal parts, thereby achieving a concealed installation effect; the baffle in the wiring hole is connected to the base through a connecting strip; before wiring, the baffle can cover the wiring hole to prevent debris from entering the expansion socket; when wiring is needed, the baffle can be removed first; the connecting strip facilitates the removal of the baffle.

[0033] It is further configured that the first live wire terminal 7 and the first neutral wire terminal 8 are separated by a first spacing 16, the second live wire terminal 10 and the second neutral wire terminal 11 are separated by a second spacing 17, one of the wiring holes 13 is located at a position corresponding to the first spacing 16, and the other wiring hole 13 is located at a position corresponding to the second spacing 17.

[0034] The beneficial effects of this arrangement are as follows: the live wire terminal pieces and the neutral wire terminal pieces of the two sets of terminal pieces are separated by a certain distance, which increases the distance between the live wire terminal pieces and the neutral wire terminal pieces, preventing improper operation during wiring from causing the wires to touch each other and cause a short circuit.

[0035] It is further configured that the spacing between the first ground terminal 9 and the first neutral terminal 8 is smaller than the first spacing 16 , and the spacing between the second ground terminal 12 and the second neutral terminal 11 is smaller than the second spacing 17 .

[0036] The beneficial effects of such a configuration are as follows: the spacing between the live wire terminal and the neutral wire terminal is further increased, and the live wire terminal, the neutral wire terminal and the ground wire terminal are easily distinguished, which helps installation and prevents wiring errors.

[0037] It is further configured that at least one moving contact piece 18 capable of turning on or off current is provided on the live copper strip 4, and at least one switch 19 cooperating with the moving contact piece 18 is provided on the inner panel 2, and the switch 19 includes a button 20 and a guide column 21 connected to the button 20, and an upper rotating shaft 22 and a lower rotating shaft 23 are respectively provided in the middle of the upper and lower sides of the button 20, and the button 20 is connected to the inner panel 2 by the upper rotating shaft 22 and the lower rotating shaft 23 so as to swing left and right, and the guide column 21 is located on the middle part of the button 20 close to the lower rotating shaft 23.

[0038] The beneficial effects of such a setting are as follows: the switch and the moving contact piece cooperate to control whether the live wire is energized. The switch on the socket in the prior art is designed in a T-shape, resulting in a smaller distance between the socket and the switch. The plug of the electrical appliance will press the switch when inserted into the socket. For example, the fast charging plug blocks the control switch during use, causing poor contact of the control switch. The switch of the utility model is designed in a 7-shape, that is, the guide column is located on the side of the button close to the lower shaft, which increases the distance between the switch and the socket, prevents the plug of the electrical appliance from pressing the switch, further improves practicality, and can adapt to the power supply of more types of electrical appliances.

[0039] It is further provided that the lower rotating shaft 23 is provided with a boss 24 , and the boss 24 is abutted between the inner panel 2 and the button 20 .

[0040] The beneficial effect of such a configuration is as follows: the distance between the switch and the socket is further increased by the raised boss on the lower shaft without affecting the normal use of the switch.

[0041] It is further configured that the outer panel 3 is provided with a surface installation opening 25 located on the top wall and a surface installation opening 25 located on the side wall at positions corresponding to both sides of the copper strip assembly, and each surface installation opening 25 is provided with a surface installation plate 26 with a thickness less than that of the outer panel 3.

[0042] The beneficial effects of such an arrangement are as follows: if an extension socket is installed without a concealed box, the surface-mounted wire is connected to the extension socket, that is, it is surface-mounted. The surface-mounted wire can be extended into the interior of the extension socket through the surface-mounted opening of the outer panel. Two surface-mounted openings are opened corresponding to the positions of the terminal pieces on both sides, one surface-mounted opening is located on the top wall and the other is located on the side wall. The surface-mounted wire can be connected from the horizontal direction or the vertical direction, which has the advantage of convenient surface-mounted wiring. Before wiring, the surface-mounted opening is blocked by a surface-mounted plate with a thickness less than that of the outer panel, which will not damage the integrity of the outer panel and prevent debris from entering, thereby ensuring aesthetics.

[0043] It is further provided that the edges of both sides of the surface mounting plate 26 are recessed with shear grooves 27 .

[0044] The beneficial effects of such arrangement are as follows: the shear groove further reduces the thickness of the edges of the surface-mounted board on both sides, making it easy to remove the surface-mounted board while ensuring that the surface-mounted board will not fall off, further facilitating surface-mounted wiring.

[0045] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
