Although there are some plug-in sockets that can be freely plugged in according to the needs of use, since the plug-in sockets need to be electrically connected, it is inevitable that the electrical connection part of the last socket will be exposed to the outside, causing electrical hazards. Of course, there are also manufacturers who will set a cover on the last socket to block the electrical connection part, but there is still a possibility that the electrical connection part between the sockets is not installed properly, which may also cause electrical hazards, and the sealing of the cover cannot solve the above-mentioned electrical safety problems.

The purpose of this utility model is to provide a combined socket structure. Even if the power module has been connected through the terminal and the terminal seat, the power module still cannot be powered. The fuse module needs to be inserted to connect the power supply to the power module.

Claiming priority, short-term patent number: HK30079311, application number 32023068320.5, priority date: February 13, 2023.

Referring to Figures 1 and 2, the combined socket structure includes two or more power modules 1 that can be plugged in sequentially. The power modules 1 are respectively provided with power lines and power lines for supplying power to the power modules 1. The power lines and power lines are independent, that is, even if the power modules 1 are reliably connected, all the power modules 1 cannot obtain power. The power lines and power lines of adjacent power modules 1 are connected to each other through the corresponding terminals 2 and the terminal blocks 3. In order to ensure that the connection between the power modules 1 is more reliable and will not loosen, etc., a locking structure is also provided between the adjacent power modules 1 to ensure that the terminals 2 and the terminal blocks 3 are reliably connected. As mentioned above, since the power supply line of the power circuit and the power supply line of the power module 1 are still not connected after the adjacent power module 1 is plugged in, this can prevent the power module 1 from being installed incorrectly and causing power safety problems, and can also prevent children from using the power module 1 indiscriminately and causing electric shock problems. After the user checks that all the power modules 1 are correctly connected, the fuse module 4 is finally plugged into the power module 1 at the rear, and the power supply line of the universal power module 1 and the power supply line of the power circuit are connected 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 plug-in of the fuse module 4 and 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.

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

Referring to FIG. 2 and FIG. 3, adjacent power modules 1 are reliably connected through a locking structure after being inserted. Specifically, the 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, and the bosses 6 are inserted into the grooves 7 to connect and fix the adjacent power modules 1. There are also mutually buckled buckles 8 and buckle grooves 9 respectively provided 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.

Referring to Figures 4 and 5, in order to ensure that the terminal 2 can have good contact after being inserted into the terminal seat 3, 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, see 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 supplying large current. 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 sheet 13 can maintain sufficient contact, and at the same time, it will be loosened when placed in use, so the distance between the clamping spring 12 and the conductive contact sheet 13 is smaller 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. Similarly, to ensure that the conductive metal sheet 19 and the plug buckle 11 can have sufficient contact surface, the contour of one end of the conductive metal sheet 19 connected to the plug buckle 11 matches the contour of the conductive contact sheet 13 and contacts with the other side of the conductive contact sheet 13.

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 inlet 20 for introducing the terminal 2, and the inlet 20 corresponds to the opening between the clamping spring 12 and the conductive contact sheet 13. In order to prevent the plug buckle 11 from shifting in the slot, a fixed groove 15 and a fixed bump 16 are respectively provided between the plug buckle 11 and the fixed slot 14, and the fixed groove 15 cooperates with the fixed bump 16. In addition, the end of the conductive contact sheet 13 of the plug buckle 11 is provided with a folded angle 17, and the corresponding fixed 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 body can ensure that the plug buckle 11 can be reliably fixed in the slot body to prevent displacement during the plugging and unplugging process.

For the power module 1, various power devices can be set according to the needs of use. However, the most commonly used power device is the power socket. The applicant has taken into account that different countries have different power operation standards and designs, such as China, Hong Kong, the United Kingdom, the United States, etc., and the power plugs and sockets between different countries are not compatible. Therefore, the utility model is aimed at the standards of the above-mentioned different countries and involves corresponding power sockets for consumers to choose. Even when faced with power equipment plugs designed for different countries, users can choose the power module 1 designed with the corresponding power socket according to different standards, and the above-mentioned different needs can be met after plugging. When traveling or on a business trip, you can bring a local standard plug connection line to connect the power module 1, and then just choose a power module 1 with a socket that meets the household electricity standards of your country to use electrical devices such as mobile phone chargers, power adapters, etc., without the need to use unsafe conversion plugs, etc., which is very flexible and convenient.

Another application of the utility model is that some power modules 1 that can convert power can be selected and inserted into the first module, and the power module 1 is used to detect and/or adjust and/or filter the voltage and/or current of the power 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 equipment. Or if the equipment has high requirements on the quality of power supply, such as audio equipment has special requirements on the frequency of power supply, then a power module 1 with a bandpass filter or a voltage stabilizer can be selected, and the module with power adjustment can be installed before the power module 1 for plugging in the electrical equipment, so as to provide appropriate power supply for subsequent electrical equipment.

The power module 1 can also be provided with a network function, such as a WIFI network module. When the power module 1 is powered on, the corresponding network access service is provided through the WIFI network module. In addition, the power module 1 can also be provided with an inductive charging module and/or a USB power supply module to provide power charging function for mobile phones and other devices.

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

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