Referring to fig. 1 and 2, the combined socket structure comprises two or more power utilization modules 1 which can be inserted in sequence. The power supply lines and the power supply lines for supplying power to the power utilization modules 1 are respectively arranged in the power utilization modules 1, and the power supply lines are independent, namely, even though the power utilization modules 1 are reliably connected, the power utilization modules 1 cannot obtain power supply. The power supply lines and the power consumption lines of the adjacent power consumption modules 1 are connected with the terminal base 3 through the corresponding terminals 2 to realize communication. In order to ensure that the connection between the power utilization modules 1 is more reliable without causing loosening or the like, a locking structure for ensuring reliable connection of the terminals 2 and the terminal holders 3 is further provided between adjacent power utilization modules 1. As described above, the power supply line of the power supply line is still not communicated with the power consumption line of the power consumption module 1 after the adjacent power consumption module 1 is plugged, so that the power consumption safety problem caused by incorrect installation of the power consumption module 1 can be prevented, and the electric shock problem caused by disordered use of the power consumption module 1 by a child can be prevented. After the user checks that all the power utilization modules 1 are correctly connected, the safety module 4 is inserted into the power utilization module 1 at the tail, and the power utilization wires of the power utilization modules 1 and corresponding power supply wires of the power supply circuit are connected through the safety module 4, so that all the power utilization modules 1 can obtain power supply, and the power utilization safety of the user is guaranteed. In order to facilitate the insertion of the safety module 4 and the power consumption module 1, the safety module 4 is also connected with the power consumption module 1 by adopting the structure of the terminal 2 or the terminal seat 3.

As mentioned above, the power supply line of the power supply line may be a live line and/or a neutral line, which is not connected to the power line of the power consumption module 1. However, it is generally possible to use at least live wires, i.e. neutral wires, which are connected to the power supply lines in the power module 1. Referring to fig. 7 and 8, the fuse module 4 is provided with a connection line for connecting the disconnected line, i.e., the live line, that is, the fuse module 4 is provided with a connection line for connecting the terminal 2 of the live line of the power line and the terminal 2 of the live line.

Referring to fig. 2 and 3, after the adjacent power utilization modules 1 are inserted, reliable connection is performed through a locking structure, wherein the specific locking structure is that mutually matched bosses 6 and grooves 7 are respectively arranged on the insertion surfaces of the adjacent power utilization modules 1, and the bosses 6 are inserted into the grooves 7 to enable the adjacent power utilization modules 1 to be connected and fixed. The lug boss 6 and the groove 7 are respectively provided with a buckle 8 and a buckling groove 9 which are mutually buckled, and after the lug boss 6 is inserted into the groove 7, the buckle 8 is matched with the buckling groove 9 to lock the positions of the lug boss 6 and the groove 7.

Wherein the contour of the conductive contact piece 13 is matched with the contour of the terminal 2, thereby ensuring that a sufficient contact area exists 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 high current is supplied. Generally, the overall contour of the contact surface adopts a planar design, and the area of the planar surface can be set correspondingly according to the current required by the actual work. The clamping spring piece 12 ensures that the terminal 2 and the conductive contact piece 13 can keep sufficient contact, and meanwhile, loosening and the like are generated when the terminal is placed and used, so that the distance between the clamping spring piece 12 and the conductive contact piece 13 is smaller than the thickness of the terminal 2. The terminals 2 in the power consumption module 1 are generally connected with the plug-in buckle 11 through wires or copper bars, and the corresponding power supply wires or power consumption wires, namely, the conductive metal sheet 19, are communicated, so as to ensure that the conductive metal sheet 19 and the plug-in buckle 11 can have enough contact surfaces, and the outline of one end of the conductive metal sheet 19 connected with the plug-in buckle 11 is matched with the outline of the conductive contact sheet 13 and is contacted with the other side of the conductive contact sheet 13.

In addition, the conductive contact piece 13 of the plug-in buckle 11 is provided with a folding angle 17 at the end, and the corresponding fixing groove 15 is provided with a clamping groove 18 matched with the folding angle 17. The design that the plug-in buckle 11 is fixed in the groove body can ensure that the plug-in buckle 11 can be reliably fixed in the groove body, so that displacement is prevented in the process of plugging.

Various electric devices can be provided for the electric module 1 according to the use requirement. But the most commonly used electrical device is an electrical outlet.
