Description

Technical Field

[0001] The utility model relates to the technical field of PoE power supply, in particular to a novel external MOS tube PoE power supply. Background Art

[0002] An external MOS tube is a MOS tube device that is independent of the main circuit board. It usually consists of high load capacity, low on-resistance and extremely low switching loss. A PoE power supply is a device used to supply power to a device. A traditional PoE power supply contains an integrated power module and MOS tube for transmitting power to the Ethernet cable, while an external MOS tube PoE power supply separates the MOS tube, providing greater flexibility. By using an external MOS tube PoE power supply, the device can be easily upgraded and maintained. If the MOS tube fails or needs to be upgraded, only the external MOS tube needs to be replaced without replacing the entire power module. A slot is usually set on the side of the PoE power supply, and a plug-in terminal is set in the slot. The plug-in terminal is connected to the main circuit board inside the PoE power supply through a wire to achieve power transmission and control. The design of the plug-in terminal allows the MOS tube to be inserted into the slot and connected to the plug-in terminal to provide power and control signals.

[0003] In the existing PoE power supply design, when the power supply falls or is impacted by external force, the MOS tube and the plug-in terminal in the slot are easily disengaged. In this case, the existing power supply usually cannot promptly warn that the MOS tube and the plug-in terminal are disengaged, which will cause power transmission to be interrupted. For devices that rely on PoE power supply, this will cause the device to lose power immediately, affecting its normal operation.

[0004] In order to solve the above problems, this application proposes a new type of external MOS tube PoE power supply. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a novel external MOS tube PoE power supply.

[0009] Preferably, the pressure warning component includes a pressure sensor and an alarm, the pressure sensor is installed on the inner wall of the cavity, the alarm is installed on the outer periphery of the fixed cylinder, and the alarm is electrically connected to the pressure sensor.

[0010] Preferably, the elastic pressure piece includes a connecting rod, a piston and a spring, the piston is slidably arranged in the cavity and abuts against the pressure sensor, the connecting rod is installed at the end of the piston away from the pressure sensor, the end of the fixed cylinder is provided with an opening connected to the cavity, the end of the connecting rod away from the piston slides through the opening, the spring is sleeved on the connecting rod and placed in the cavity, and the two ends of the spring are respectively connected to the piston and the inner wall of the end of the fixed cylinder, and the limit block is installed at the end of the connecting rod away from the piston.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] like Figure 1 and Figure 2 As shown, the utility model proposes a novel external MOS tube PoE power supply, including a power supply body 1;

[0020] In this embodiment, a slot is provided on the side of the power supply body 1, and the MOS tube body 2 is inserted into the slot.

[0021] In this embodiment, a fixing cylinder 3 is installed at the bottom of the power supply body 1, and a cavity is opened in the fixing cylinder 3. A pressure warning component 4 and an elastic pressure component 5 abutting against the pressure warning component 4 are installed in the cavity. The end of the elastic pressure component 5 slides through the end of the fixing cylinder 3 and is connected to a limiting block 6, and the limiting block 6 abuts against the MOS tube body 2.

[0022] In this embodiment, the pressure warning component 4 includes a pressure sensor 41 and an alarm 42. The pressure sensor 41 is installed on the inner wall of the cavity, and the alarm 42 is installed on the outer periphery of the fixed cylinder 3, and the alarm 42 is electrically connected to the pressure sensor 41. The elastic pressure component 5 includes a connecting rod 51, a piston 52 and a spring 53. The piston 52 is slidably arranged in the cavity and abuts against the pressure sensor 41. The connecting rod 51 is installed at the end of the piston 52 away from the pressure sensor 41. The end of the fixed cylinder 3 is provided with an opening connected to the cavity, and the end of the connecting rod 51 away from the piston 52 slides through the opening. The spring 53 is sleeved on the connecting rod 51 and placed in the cavity, and the two ends of the spring 53 are respectively connected to the piston 52 and the inner wall of the end of the fixed cylinder 3. The limit block 6 is installed at the end of the connecting rod 51 away from the piston 52.

[0023] It should be noted that: when the power supply body 1 accidentally falls to the ground, the MOS tube body 2 can be limited by the limit block 6. When the MOS tube body 2 is separated from the plug-in terminal in the slot, the position of the limit block 6 against the MOS tube body 2 will change, and the spring 53 will also undergo elastic deformation. The pressure value of the piston 52 pressing on the pressure sensor 41 will change, and the alarm 42 can be used to give a timely warning to remind the staff that the MOS tube body 2 is separated from the plug-in terminal. This structure can give a timely warning when the MOS tube body 2 is separated from the plug-in terminal, thereby ensuring the normal operation of the equipment.

[0024] In a specific embodiment, the end of the fixing tube 3 is connected with an air pipe 7 which is communicated with the cavity and the slot respectively.

[0025] It should be noted that when installing the MOS tube body 2, the connecting rod 51 can be pulled outward through the limit block 6, so that the piston 52 can move in the fixed cylinder 3, pushing the gas in the fixed cylinder 3 into the slot along the air pipe 7, so that dust can be blown out of the slot, effectively preventing poor contact.

[0026] In a specific embodiment, a rubber layer is provided on one side of the limiting block 6 close to the MOS tube body 2 .

[0027] The provided rubber layer can increase the friction between the limiting block 6 and the MOS tube body 2 .

[0028] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
