[0028] Reference Figure 1 and Figure 2, a combined socket structure, including two or more power modules 1 that can be plugged in sequentially. The power modules 1 are respectively provided with a power supply line and a power supply line for supplying power to the power modules 1, and the power supply line and the power supply line are independent, that is, even if the power modules 1 are reliably connected, all the power modules 1 cannot obtain power. The power supply lines and power supply lines of adjacent power modules 1 are connected to the terminal block 3 through the corresponding terminals 2 to achieve communication. In order to ensure that the connection between the power modules 1 is more reliable and will not cause loosening, etc., a locking structure is also provided between the adjacent power modules 1 to ensure that the terminals 2 are reliably connected to the terminal block 3. As mentioned above, since the power supply line of the power supply line and the power supply line of the power module 1 are still not connected after the adjacent power modules 1 are plugged in, this can prevent the power safety problems caused by the improper installation of the power module 1, and also prevent the electric shock problems caused by the indiscriminate use of the power module 1 by children. After the user has checked that all the power modules 1 are correctly connected, the user finally plugs the fuse module 4 into the power module 1 at the rear, and connects the power lines of the general power modules 1 and the corresponding power supply lines of the power line through the fuse module 4, so that all the power modules 1 can obtain power supply to ensure the user's power safety. In order to facilitate the plugging of the fuse module 4 with the power module 1, the fuse module 4 also uses the structure of the terminal 2 or the terminal seat 3 to connect with the power module 1.

[0029] As mentioned above, the power supply line of the power supply circuit and the power circuit of the power module 1 are not connected, and can be a live wire and / or a neutral wire. However, the generally adopted solution is to use at least a live wire, that is, the neutral wire can be connected to the power circuit in the power module 1. Figure 7 and Figure 8 , the insurance module 4 is provided with a connection line for connecting the disconnected line, that is, the live wire, that is, the insurance module 4 is provided with a connection line, which can connect the terminal 2 of the live wire of the power supply line and the terminal 2 of the live wire in the power line. The insurance module 4 is inserted into the terminal 2 or the terminal seat 3 of the power module 1 that is inserted last to connect the above-mentioned lines. At the same time, in order to facilitate the user to observe whether the insurance module 4 has been correctly inserted and is working properly, the insurance module 4 is also provided with a terminal 2 connected to the neutral wire of the power supply line, and a display light 5 is connected to the terminal 2 of the neutral wire and the terminal 2 of the live wire. When the insurance module 4 is correctly inserted and the relevant lines are connected, the display light 5 will be connected in series to the live wire and the neutral wire of the power supply to obtain power and display, and the user can understand whether the insurance module 4 is working properly by observing the status of the display light 5.

[0030] Reference Figure 2 and Figure 3After the adjacent power modules 1 are inserted, they are reliably connected through the locking structure. The specific locking structure is that the plug-in surfaces of the adjacent power modules 1 are respectively provided with mutually matching bosses 6 and grooves 7. The bosses 6 are inserted into the grooves 7 to connect and fix the adjacent power modules 1. There are also buckles 8 and buckle grooves 9 that are buckled with each other between the bosses 6 and the grooves 7. After the bosses 6 are inserted into the grooves 7, the buckles 8 and the buckle grooves 9 cooperate to lock the positions of the bosses 6 and the grooves 7. In order to realize the unfastening of the buckles 8 and the buckle grooves 9, the buckles 8 are provided with a button 10. By pressing the button 10 to disengage the buckles 8 from the buckle grooves 9, the bosses 6 can be pulled out from the grooves 7, thereby disassembling the adjacent power modules 1 that were originally connected together.

[0031] Reference Figure 4 and Figure 5 In order to ensure that the terminal 2 can have good contact after being inserted into the terminal seat 3, and to prevent arcing and overheating caused by poor contact during plugging and unplugging, the terminal seat 3 is provided with a plug buckle 11 corresponding to each terminal 2, and the plug buckle 11 includes a clamping spring 12 and a conductive contact piece 13, respectively. Figure 6 . The contour of the conductive contact piece 13 matches the contour of the terminal 2, thereby ensuring that there is sufficient contact area between the terminal 2 and the conductive contact piece 13, so as to ensure that the resistivity can be reduced as much as possible when a large current is supplied. Generally speaking, the overall contour of the contact surface adopts a planar design, and the area of ​​the plane can be set accordingly according to the current required for actual work. The clamping spring 12 is to ensure that the terminal 2 and the conductive contact piece 13 can maintain sufficient contact, and at the same time, it will not be loosened when placed for use, so the spacing between the clamping spring 12 and the conductive contact piece 13 is less than the thickness of the terminal 2. The terminal 2 in the power module 1 is generally connected to the plug buckle 11 through wires or copper bars, etc., and connected to the corresponding power supply line or power line, that is, the conductive metal sheet 19. In order to ensure that the conductive metal sheet 19 and the plug buckle 11 have sufficient contact surface, the contour of the end of the conductive metal sheet 19 connected to the plug buckle 11 matches the contour of the conductive contact piece 13 and contacts with the other side of the conductive contact piece 13.

[0032] In order to facilitate the smooth insertion of the terminal 2 into the terminal seat 3, the plug buckle 11 is installed in the corresponding fixed slot 14 of the terminal seat 3. The fixed slot 14 is provided with an introduction port 20 for introducing the terminal 2, and the introduction port 20 corresponds to the opening between the clamping spring 12 and the conductive contact piece 13. In order to prevent the plug buckle 11 from shifting in the slot, a fixing groove 15 and a fixing protrusion 16 are respectively provided between the plug buckle 11 and the fixed slot 14, and the fixing groove 15 cooperates with the fixing protrusion 16. In addition, a folded angle 17 is provided at the end of the conductive contact piece 13 of the plug buckle 11, and the corresponding fixing groove 15 is provided with a card slot 18 that cooperates with the folded angle 17. The above design of fixing the plug buckle 11 in the slot can ensure that the plug buckle 11 can be reliably fixed in the slot to prevent displacement during the plugging and unplugging process.

[0033] For the power module 1, various power devices can be set according to the needs of use. But the most commonly used power device is the power socket. The inventor takes into account that different countries have different power supply operation standards and designs, and the power plugs and sockets between different countries are not compatible. Therefore, the utility model is directed to the standards of the above-mentioned different countries, and respectively involves corresponding power sockets for consumers to choose. Even when faced with power device plugs designed for different countries, users can choose power modules 1 designed for corresponding power sockets according to different standards, and the above-mentioned different needs can be met after plugging. For example, when going on a business trip or traveling, you can bring a plug connection line of the local standard to connect the power module 1, and then just choose the power module 1 with the socket of your own country's power standard, you can use the power equipment, such as mobile phone chargers, power adapters, etc., without using less safe conversion plugs, etc., which is very flexible and convenient.

[0034] Another application of the utility model is that some power modules 1 that can convert power can be selected and installed in the first module. The power module 1 can detect and / or adjust and / or filter the voltage and / or current of the power supply before supplying power to the subsequent power modules 1. For example, the power supply voltage of different countries can be adapted without changing the adaptation voltage of the power-consuming equipment. Or if the equipment has high requirements on the quality of the power supply, such as audio equipment has special requirements on the ripple of the power supply, a power module 1 with a ripple filter or a voltage stabilizer can be selected, and the module with power adjustment can be installed before the power module 1 that is plugged into the power-consuming equipment, so as to provide suitable power supply for the subsequent power-consuming equipment.

[0035] The power module 1 may also be provided with a network function, such as a WIFI network module. When the power module 1 is powered on, the WIFI network module provides corresponding network access services. In addition, the power module 1 may also be provided with an inductive charging module and / or a USB power supply module to provide a power charging function for devices such as mobile phones.

[0036] It can be seen that the combined socket structure involved in the utility model can set the corresponding functional modules in the power module 1 according to different user needs, and then meet different usage needs after plugging in and obtaining power, which is very flexible and convenient.

[0037] Of course, the various applications and embodiments listed above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
