[0027] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] The PoE power supply is a power supply module based on the PoE technology. The RJ-45 interface set on the PoE power supply is inserted with an RJ-45 connector containing a wire for connecting network devices and transmitting power. Traditional PoE power supplies on the market all use desktop adapter solutions, that is, the PoE power supply is placed on the desktop for use. This type of PoE power supply is not conducive to installation in a weak current box or other distribution cabinet, and there are installation limitations when used; and the outer shell of the PoE power supply is made of plastic shell, and the heat dissipation performance of the plastic shell is not ideal. When used for 90W power supply, the temperature rise of the components is relatively high, and the high temperature of the components will affect the stability of use; and if the RJ-45 interface set by the PoE power supply is not inserted with an RJ-45 connector, dust is easy to accumulate in the RJ-45 interface during long-term placement. When used again, the dust will cause poor contact between the RJ-45 interface and the RJ-45 connector, causing network instability and other faults. In order to solve the problems existing in the above-mentioned prior art, this application proposes a new type of guide rail PoE power supply.

[0029] Refer to the instruction manual Figures 1 to 8 A novel guide rail PoE power supply comprises a PoE power supply body 1, an RJ-45 interface is arranged on the PoE power supply body 1, the RJ-45 interface is used to connect the RJ-45 connector, a clip 2 is fixedly arranged on the PoE power supply body 1, the clip 2 is fixedly installed on the PoE power supply body 1 by screws, and the clip 2 is used to fix the PoE power supply body 1 on the guide rail; a dustproof mechanism 3 is arranged on the PoE power supply body 1, and the dustproof mechanism 3 comprises a positioning member, a mounting plate 31 and a dustproof plate 32, the dustproof plate 32 is slidably arranged on the mounting plate 31, the positioning member is used to position the dustproof plate 32 on the mounting plate 31, and the dustproof plate 32 is used to shield the RJ-45 interface;

[0030] The PoE power supply body 1 is also provided with a fixing mechanism 4 , which includes an adapter seat 41 , on which a card seat 42 is fixedly provided, and a card slot 21 is provided on the fastener 2 , and the adapter seat 41 is tightly fitted with the inner wall of the card slot 21 .

[0031] It should be noted that the fastener 2 is configured as a butterfly spring guide rail fastener. After the guide rail compatible with the fastener 2 is installed in the specified position, the fastener 2 is installed on the guide rail to achieve the positioning of the PoE power supply body 1, which is conducive to installing the PoE power supply body 1 in a low-voltage box or other distribution cabinet.

[0032] The specific implementation scenario is as follows: when the RJ-45 interface set on the PoE power supply body 1 is not fully used, the dustproof plate 32 is driven to move by the positioning member, so that the dustproof plate 32 moves to the front of the RJ-45 interface, and the RJ-45 interface is shielded by the dustproof plate 32, effectively preventing external dust from entering the RJ-45 interface. When the PoE power supply body 1 needs to be installed in a weak current box or other power distribution cabinet, a track is set in the weak current box or power distribution cabinet. At this time, it is necessary to install the fastener 2 on the PoE power supply body 1, first fit the fastener 2 with the PoE power supply body 1, and then drive the adapter seat 41 to move, so that the adapter seat 41 and the fastener 2 are tightly fitted, and the fastener 2 is assisted in positioning by the adapter seat 41, and then the fastener 2 is fixed to the PoE power supply body 1 with screws, and finally the fastener 2 is installed on the guide rail to complete the positioning and installation of the PoE power supply body 1.

[0033] Refer to the instruction manual Figure 5 and Figure 6 In order to facilitate the adjustment of the position of the dustproof plate 32 according to the use requirements and to position the dustproof plate 32, specifically, the dustproof mechanism 3 also includes a limiting shaft 331, the mounting plate 31 is fixedly arranged on the PoE power supply body 1, a through hole 311 is opened on the mounting plate 31, a positioning hole 312 is opened on the inner wall of the through hole 311, a slide groove 321 is opened on the dustproof plate 32, a moving seat 33 is slidably arranged in the slide groove 321, the limiting shaft 331 is fixedly arranged on the moving seat 33, the limiting shaft 331 is adapted to the positioning hole 312 and the through hole 311, an elastic member 34 is arranged in the slide groove 321, the elastic member 34 is arranged as a spring, the spring is fixedly arranged with the moving seat 33, and one end of the spring away from the moving seat 33 is fixedly arranged with the inner wall of the slide groove 321.

[0034] It should be noted that a limiting groove is provided on the mounting plate 31, and a guide seat is fixedly arranged on the dustproof plate 32. The guide seat is slidably arranged in the limiting groove. A guide rod is also fixedly arranged in the limiting groove. The guide seat is slidably sleeved on the guide rod. The guide seat guides and limits the movement of the dustproof plate 32 on the mounting plate 31. The limiting means preventing the dustproof plate 32 from moving out of the mounting plate 31.

[0035] In this embodiment, the default position of the limit shaft 331 is in the positioning hole 312 located below, that is, the default state of the dust cover 32 blocks the RJ-45 interface to prevent external dust from entering the RJ-45 interface. When the RJ-45 interface needs to be used, the dust cover 32 needs to be adjusted. First, the limit shaft 331 is pushed toward the through hole 311. The movement of the limit shaft 331 drives the moving seat 33 to move. During the movement of the moving seat 33, the elastic member 34 is compressed. When After the limiting shaft 331 is located in the through hole 311, the limiting shaft 331 is pushed upward along the length direction of the through hole 311, and the dustproof plate 32 is driven to move upward during the upward movement of the limiting shaft 331. When the limiting shaft 331 and the positioning hole 312 located above are at the same horizontal height, the limiting shaft 331 is pushed to move to the left, and the limiting shaft 331 is assisted to move under the action of the elastic force of the elastic member 34. The limiting shaft 331 is clamped with the positioning hole 312 located above, thereby realizing the positioning of the dustproof plate 32.

[0036] Refer to the instruction manual Figure 2 and Figure 3 When the PoE power supply body 1 needs to be inspected and maintained, in order to facilitate the disassembly of the shell of the PoE power supply body 1, specifically, the PoE power supply body 1 includes a shell, the shell includes a shell 11 and a cover plate 12, the shell 11 and the cover plate 12 are fixed by screws, a connecting seat 111 is fixedly provided on the shell 11, and a connecting seat 2 121 is fixedly provided on the cover plate 12, and the connecting seat 111 is adapted to the connecting seat 2 121.

[0037] It should be noted that a PCB board is fixedly arranged in the shell 11, and the PCB board is electrically connected to the Ethernet power supply PSE controller, capacitors and high-voltage capacitors, magnetic beads, filter capacitors, DC input sockets and indicator lights. A thermal pad 112 is fixedly arranged in the shell 11, and the thermal pad 112 is in contact with the PCB board, and the thermal pad 112 can assist in cooling the PCB board. A plurality of heat dissipation holes are arranged on the shell 11, and a dustproof net is fixedly arranged in the heat dissipation holes, and the heat dissipation holes can accelerate the heat dissipation in the PoE power supply body 1.

[0038] It should also be noted that the shell 11 and the cover plate 12 are both configured as galvanized metal plates. The galvanized metal plates not only have a good heat dissipation effect, but are also anti-corrosive and anti-rust, thereby extending the service life.

[0039] In this embodiment, when the shell 11 and the cover plate 12 need to be assembled, the second connecting seat 121 is aligned with the corresponding first connecting seat 111, and then the shell 11 and the cover plate 12 are fixed by screws.

[0040] Refer to the instruction manual Figure 7 and Figure 8The operation of installing the snap-fit ​​component 2 on the PoE power supply body 1 by screws is relatively complicated. In order to reduce the operating steps of installing the snap-fit ​​component 2 on the PoE power supply body 1 and make the operation simpler, specifically, the fixing mechanism 4 includes an elastic component 2 43, a guide groove 122 is opened on the cover plate 12, the adapter seat 41 is slidably set in the guide groove 122, and an elastic component 2 43 is set between the guide groove 122 and the adapter seat 41. The elastic component 2 43 is set as a spring, and the spring is fixed to the adapter seat 41. One end of the spring away from the adapter seat 41 is fixed to the inner wall of the guide groove 122.

[0041] It should be noted that if it is necessary to fix the fastener 2 on the PoE power supply body 1, first push the two sockets 42 to move the two sockets 42 away from each other. During the movement of the sockets 42, the elastic member 43 is compressed. When the sockets 42 move to a certain position, place the fastener 2 at the specified position on the PoE power supply body 1, and then release the socket 42. Under the action of the elastic force of the elastic member 43, the two sockets 42 approach each other, and the socket 42 positions the fastener 2. Using the socket 42 instead of screws to fix the fastener 2 on the PoE power supply body 1 makes the operation simpler and more convenient.

[0042] Refer to the instruction manual Figure 7 In order to further assist in installing the snap fastener 2 on the PoE power supply body 1, specifically, the fixing mechanism 4 also includes a limit seat 1 44 and a limit seat 2 45, both of which are in contact with the snap fastener 2, and both of which are fixedly arranged on the cover plate 12.

[0043] It should be noted that the fastener 2 is placed between the first limiting seat 44 and the second limiting seat 45 , and the first limiting seat 44 and the second limiting seat 45 cooperate to limit the fastener 2 , which makes the installation of the fastener 2 more efficient.

[0044] Refer to the instruction manual Figure 7 Since the limit seat 1 44 and the limit seat 2 45 are set on the cover plate 12, the back side of the cover plate 12 is not flat enough, and the cover plate 12 may not be stable enough when placed on the desktop. In order to stably place the cover plate 12, four support columns 123 are fixedly set on the cover plate 12, and the four support columns 123 are symmetrically arranged in pairs.

[0045] It should be noted that the support column 123 provides stable support for the PoE power supply body 1 .

[0046] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
