As shown in fig. 1 to 2, a power supply module 1 for an intelligent control panel, the power supply module 1 includes a power supply base 11, a power supply board 12 and a surface cover 13, the power supply board 12 is disposed in the power supply base 11, the surface cover 13 is mounted on an opening of the power supply base 11, the power supply board 12 is provided with at least two terminals 121, an isolation slot 111 is disposed in the power supply base 11, and the terminals 121 are located in the isolation slot 111; an insulating partition board is arranged in the isolation groove 111, and the insulating partition board 1111 isolates the adjacent posts 121.

Specifically, the intelligent control panel comprises a power supply assembly 1 and a shell assembly 2, wherein the power supply assembly 1 supplies power for being installed on the shell assembly 2. The power supply base 11 is a hollow shell structure with an opening at the lower end, the power supply board 12 is installed inside the power supply base 11, the surface cover 13 covers the opening of the power supply base 11 to ensure the sealing performance of the power supply assembly 1, and the power supply board 12 is electrically connected with a wire to provide energy for the intelligent control panel.

In this embodiment, the power board 12 is provided with 4 terminals 121, the position corresponding to the terminals 121 in the power socket 11 is provided with an isolation slot 111, three insulation partition plates 1111 are arranged in the isolation slot 111 and distributed at equal intervals, and the isolation slot 111 is divided into four parts which just correspond to the 4 terminals 121. When the power panel 12 is installed in the power socket 11, an insulating partition 1111 is disposed between the adjacent posts 121, and the insulating partition 1111 separates the adjacent posts 121. Because control panel's structural design's very compactness, so the interval between adjacent post 121 is little, leads to taking place easily to interfere between the adjacent post 121, leads to the short circuit, and sets up isolation groove 111, keeps apart post 121, avoids taking place the short circuit of circuit, has improved intelligent control panel's stability in use.

Preferably, the insulating partition 1111 is made of a known insulating material.

Furthermore, the power socket 11 is provided with a wiring hole 112 communicating with the isolation groove 111, and a wire passes through the wiring hole 112 and is electrically connected with the terminal 121.

Specifically, the terminal 121 is located on the power board 12, the power board 12 is installed in the power socket 11, the power socket 11 isolates the power board 12 from the outside, the power board 12 needs to be electrically connected to a wire, and the wire provides power to the power board 12, so as to drive the intelligent control panel. In order to facilitate the connection of the wires with the terminals 121, the power socket 11 is provided with wiring holes 112 communicating with the isolation groove 111 at positions corresponding to the terminals 121, each wiring hole 112 individually corresponds to one terminal 121, and adjacent wiring holes 112 are not communicated with each other to isolate the wires. A lead penetrates through the wiring hole 112 to be electrically connected with the wiring post 121, and the diameter of the wiring hole 112 is larger than that of the lead, so that the lead can smoothly pass through the wiring hole 112; meanwhile, the wire shields the wiring hole 112, so that the power socket 11 forms a relatively closed space to protect the power board 12.

Further, a groove 115 recessed downward is formed in the upper end surface of the power socket 11, and the wiring hole 112 is formed in the groove 115.

Specifically, the power socket 11 is usually installed in the wall body, for the stability of installation, too many gaps can not be left between the upper end face of the power socket 11 and the wall body, the space left for the wire is very small, the wire can be extruded like this, the wire can lead to the insecure connection of the wire and the wiring terminal 121 after being extruded for a long time, so a groove 115 of the downward sunken stroke of the upper end face of the power socket 11, the wiring hole 112 is opened in the groove 115, a containing cavity is formed between the groove 115 and the wall body, the wire can be contained in the containing cavity, the wire can not be extruded like this, and therefore, the connection firmness between the wiring terminal 121 and the wire is improved.

Furthermore, a fixing member 122 for fixing a wire is further installed on the binding post 121, an adjusting hole communicated with the isolation groove 111 is formed in the power supply seat 11, and the fixing member 122 can be adjusted through the adjusting hole to adjust the tightness degree of the wire and the binding post 121.

Specifically, in order to make the installation between the lead and the post 121 more stable, the post 121 is further provided with a fixing member 122. In this embodiment, the terminal 121 is a hollow cylinder, the cylinder is provided with a threaded through hole, a fixing member 122 is inserted into the threaded through hole, the fixing member 122 is a screw, and the length of the fixing member 122 is longer than the depth of the threaded through hole. When the wire is inserted into the space of the binding post 121, the tightness degree between the wire and the binding post 121 is adjusted by adjusting the position of the fixing member 122 on the binding post 121, and the threaded connection is a detachable fixed connection which is widely used, and has the advantages of simple structure, reliable connection, convenient assembly and disassembly and the like.

Because the binding post 121 is arranged inside the power supply seat 11 and the fixing member 122 is also positioned inside the power supply seat 11, an adjusting hole communicated with the isolation groove 111 is formed in the power supply seat 11, so that an operator can conveniently adjust the tightness degree of the wire and the binding post 121; and each adjusting hole individually corresponds to one fixing member 122, and adjacent wiring holes 112 do not communicate with each other.

Furthermore, the power socket 11 is provided with a heat sink 114.

Specifically, the power supply base 11 and the surface cover 13 are combined into a closed space, and the power supply board 12 is installed between the power supply base 11 and the surface cover 13. The power board 12 generates a large amount of heat during operation, because the power board 12 is located between the power socket 11 and the surface cover 13, the heat generated by the operation of the power board 12 cannot be discharged, so that the temperature in the power socket 11 rises continuously until the optimum operating temperature of the power board 12 is exceeded. In order to avoid the damage of the power board 12 due to high temperature, when the temperature is too high, the power board 12 will automatically reduce the working power to reduce the heat generation, so that the temperature in the power socket 11 is reduced to the optimum working temperature of the power board 12, and the power board 12 will recover to the normal working power. Resulting in the power strip 12 not maintaining maximum operating efficiency for a long period of time. Therefore, the heat sink 114 is disposed on the power socket 11 to exchange the cold air outside the power socket 11 with the hot air inside the power socket 11. The temperature in the power socket 11 is reduced, so that the temperature in the power socket 11 is always kept at the optimal working temperature of the power board 12, and the power board 12 can always keep the highest working power.
