Description

Technical Field

[0001] The utility model relates to the fields of a housing, a POE power supply and a POE power supply group, and in particular to a housing that can be infinitely spliced, a POE power supply that can be infinitely spliced and a POE power supply group. Background Art

[0002] POE utilizes existing Ethernet CAT-5 cabling infrastructure to simultaneously transmit data and supply power over a single, unmodified Ethernet cable. This ensures that the cable not only transmits data signals for Ethernet and IP-based terminals but also provides DC power to these devices. When power cord adapters are inconvenient to deploy, Ethernet cables can easily provide power over distances up to 100 meters. Existing power supply housings are often independent of other housings and cannot be spliced together, making installation difficult. Furthermore, spliced housings often have complex structures and are costly.

[0003] Chinese Patent Publication No. CN207460204U discloses a POE power supply comprising a power supply housing, a power cover mounted on the top of the housing, a movable bolt mounted on the front surface where the power supply housing and the power supply housing meet, an indicator light mounted on the front surface of the housing, an Ethernet input port mounted below the indicator light, an Ethernet output port mounted to the right of the Ethernet input port, and a power switch mounted to the right of the Ethernet output port, a charging plug mounted at the bottom of the housing, a heat dissipation hole mounted below the charging plug, fixing screws mounted at the four corners of the bottom of the housing, a power supply port mounted on the rear surface of the housing, a small fan mounted inside the housing, a resistor mounted on the central axis of the housing, and a wire jack mounted inside the housing. This POE power supply has diverse functions, high power supply efficiency, and is safe and reliable. The POE power supply described in this patent cannot be connected to other POE power supplies during use, making installation and connection inconvenient when multiple POE power supplies are required.

[0004] Chinese Patent Publication No. CN114598133A discloses an intelligent splicing adaptive power adapter, comprising a power adapter body, a connecting wire disposed on the power adapter body, a fixed frame disposed on the power adapter body, a sliding frame disposed on the fixed frame, and a storage frame disposed on the sliding frame for storing the connecting wires. A drive assembly is disposed within the fixed frame for driving the sliding frame to perform directional movement, so that the drive assembly drives the storage frame to move synchronously through the sliding frame. A power assembly is disposed on the fixed frame for operating the drive assembly. In this intelligent splicing adaptive power adapter, the sliding frame drives the storage frame to perform directional movement through the cooperation of the power assembly and the drive assembly. Turning the knob one circle causes spherical body 1 to engage with spherical body 2, so that trapezoidal block 1, as the drive plate descends, squeezes trapezoidal block 2, causing the gear body to engage the rack body to drive the sliding frame to move, and the storage frame slides out to store the connecting wires. Although this patent achieves the splicing of power adapters, its splicing structure is relatively complex, costly, and prone to failure, resulting in the inability to achieve splicing.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The preferred embodiment of the present invention is a shell that can be infinitely spliced, a POE power supply and a POE power supply group; Figure 1-3 and Figure 10-11 As shown, the POE power supply group includes at least two groups of spliced and connected POE power supplies 1. Each group of POE power supplies 1 includes a shell, with through holes set on the left and right sides of the shell, and a control board 17 set inside. The shell is formed by connecting a bottom shell 10 and a top cover 11. The control board is placed in the bottom shell, and a power socket 15 and a network interface 12 are respectively set on both sides of the control board. There are two groups of network interfaces, namely POE interface and LAN interface. The POE power supply is powered by connecting to the mains through the power socket and works through the network interface. A splicing slot assembly 14 is provided on the left side of the shell, and a splicing column 16 is provided on the right side corresponding to the splicing slot assembly. The two groups of POE power supplies can be spliced by inserting the splicing column into the splicing slot assembly. Since each group of shells is provided with a splicing slot assembly and a splicing column on both sides, the POE power supplies can be spliced infinitely to form a POE power supply group.

[0032] Specifically, such as Figure 1-2 As shown, the splicing slot assembly 14 includes an upper card post 140 and a lower card post 141 arranged on the left side of the housing. A slot is formed between the upper card post and the lower card post, and both the upper card post and the lower card post are L-shaped, so that the slot is arranged in a T-shape. The splicing column is arranged on the right side of the housing, and the slot corresponding to the splicing column is also arranged in a T-shape. The splicing column can be inserted into the slot to connect the splicing column to the splicing slot assembly, thereby realizing the splicing of two sets of POE power supplies. It should be noted that the slot can also be set to be L-shaped, in which case the splicing column is correspondingly L-shaped.

[0033] Furthermore, if Figure 1-2 As shown, the upper clamping column 140 is set on the top cover 11, and the lower clamping column 141 is set on the bottom shell 10, which facilitates mold opening and formation. After the bottom shell and the top cover are connected and locked, a fixed slot can be formed between the upper clamping column and the lower clamping column. In order to prevent the POE power supply from being spliced in reverse, the lengths of the upper clamping column and the lower clamping column in the vertical direction should be set to be different, and the vertical heights of the two sides of the splicing column set on the top cover are also different, but the heights on both sides are the same as the vertical heights of the upper clamping column and the lower clamping column. For example, when the splicing column is L-shaped or T-shaped, the upper and lower heights are different. Specifically, the splicing column can only be inserted into the splicing slot assembly when the top covers of the spliced POE power supplies are on the same surface, thereby achieving a fool-proof effect for POE power supply splicing. An arc groove 143 is provided on the lower clamping column 141, and a convex column 160 is provided on the splicing column corresponding to the arc groove. When the splicing column is inserted into the slot 142, the convex column is sensed to be stuck in the arc groove, indicating that the POE power supply is spliced. This facilitates the splicing of the POE power supply.

[0034] Furthermore, if Figure 3-5 and Figure 7-8 As shown, the bottom shell 10 is provided with multiple sets of limiting posts 101, and the control panel 17 is provided with limiting slots 171 corresponding to the limiting posts. When installing the control panel, the limiting slots are snapped into the limiting posts to secure the control panel within the bottom shell, preventing the control panel from shaking. Furthermore, the bottom of the bottom shell is provided with multiple sets of support posts 102, and the lower end surface of the control panel is placed on the support posts. The support posts create a hollow space between the control panel and the bottom shell, preventing direct contact between the control panel and the bottom shell and improving the control panel's heat dissipation capacity. An indicator light 170 is also provided near the side of the network interface 12. Since there are two sets of network interfaces, the distance between the left and right sides of the control panel is relatively small. Placing the indicator light there reduces the space required for the indicator light and increases its brightness. A light-transmitting plate 110 is provided on the top cover corresponding to the indicator light, allowing the indicator light to be used to observe the working status of the POE power supply. At the same time, display marks 111 are provided on the top shell corresponding to the different network sockets to facilitate the use of the network sockets.

[0035] Furthermore, if Figure 3-5 and Figure 7-8 As shown, the other end of the control board 17 is connected to the power socket 15, and the end of the power socket is connected to a fixing plate 150. A socket fixing groove 104 is provided on one side of the bottom shell and the top cover corresponding to the fixing plate, and a socket support platform 103 is provided in the shell corresponding to the power socket. The upper and lower ends of the power socket are in contact with the two sets of socket support platforms, and the fixing plate is placed in the socket fixing groove. Oblique clamping blocks 151 are provided on the left and right sides of the power socket, and a socket clamping groove 105 is formed inside the socket fixing groove. The socket clamping groove generates a clamping force on the oblique clamping block, so that the connection of the power socket on the bottom shell is more stable, and multiple plugging and unplugging will not affect the connection of the power interface.

[0036] Furthermore, if Figure 5-6 and Figure 8-9As shown, the bottom shell 10 has a sealing post 106 on the side facing the top cover, which is equipped with multiple sets of ultrasonic welding blocks 107. The top cover is provided with a sealing groove 112 corresponding to the sealing post. The sealing post is inserted into the sealing groove to seal the shell, and the bottom shell and top cover are connected and fixed by ultrasonic welding. An inner baffle 113 is provided inside the sealing groove. The inner baffle is higher than the outer baffle. When connected, the bottom shell and top cover can only move perpendicular to the bottom shell and cannot move in the left or right direction due to the blocking force of the inner baffle, thus ensuring a unique assembly direction.

[0037] Furthermore, if Figure 1-2 As shown, mounting blocks 13 are provided on both the front and rear sides of the bottom shell 10. The mounting blocks are integrally formed with the bottom shell, and the two groups of mounting blocks are diagonally arranged. The mounting blocks are connected to the bottom shell by reinforcing ribs 130 to increase the strength of the mounting blocks. Fixing holes are provided on the mounting blocks, and the mounting blocks are fixed through the fixing holes, so that the POE power supply is installed in the position to be installed, and due to the presence of the reinforcing ribs, its strength is also guaranteed. A sunken surface 100 is provided on the upper end face of the top cover, and information such as the nameplate of the product can be pasted on the sunken surface. It should be noted that in the present utility model, the shell is applied to the POE power supply, and can also be applied to other power adapters that need to be spliced. The application of the above shell to splice other electronic products should also fall within the protection scope of the present utility model.

[0038] It should be understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
