Technical Field
[0001] This utility model belongs to the field of MTCA chassis technology, specifically relating to a plug-in MTCA chassis. Background Technology
[0002] In existing MTCA chassis, hot-swapping fan modules often requires connecting them via a fan adapter plate before inserting them into the chassis. This process is cumbersome, requiring not only an additional fan adapter plate but also ensuring accurate connections between the adapter plate, the fan module, and the chassis. This makes the operation difficult and hinders routine chassis maintenance. Furthermore, the numerous connection points necessitate providing sufficient operating space within the chassis, resulting in a relatively large chassis size that may not meet the needs of some users.
[0003] Therefore, there is an urgent need for a plug-in MTCA chassis that is compact, small in size, and easy to assemble with fan modules. Utility Model Content

Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1
[0025] like Figures 1-4As shown, a plug-in MTCA chassis includes a rear panel 1, a front panel 2, a power module 3, a fan module 4, and a housing 5. The power module 3 and fan module 4 are existing technologies. The power module 3 mainly consists of a circuit board, power conversion circuit, control circuit, filter circuit, protection circuit, and various interfaces 301, etc. These components work together to ensure stable and reliable power output, meeting the power requirements of the equipment. The fan module 4 consists of fan blades, a motor, control circuit, housing, and protective mesh, etc. These components cooperate to achieve normal fan operation and heat dissipation. In this technical solution, the power module 3 is located on the back of the rear panel 1. One end of the housing 5 is connected to the rear panel 1 and covers the power module 3. The front panel 2 is connected to the other end of the housing 5, and the front panel 2, rear panel 1, and housing 5 form a box-shaped structure. It is important to note that multiple expansion cards 201 are inserted into the front panel 2. A fan mounting position 205 for inserting the fan module 4 is reserved between the front panel 2 and the end opening of the housing 5. The edges of the multiple expansion cards 201 and the inner wall of the housing 5 can form a guide channel corresponding to the fan mounting position 205. The connector 401 on the fan module 4 can move along the guide channel to connect with the interface 301 on the power module 3. The reserved fan mounting position 205 between the front panel 2 and the end opening of the housing 5, and the guide channel formed by the edges of the expansion cards 201 and the inner wall of the housing 5, allow the fan module 4 to be accurately inserted along the guide channel during installation, reducing the installation difficulty and improving the assembly and disassembly efficiency. Furthermore, integrating the connector 401 for connecting the fan module 4 onto the power module 3 allows the connector 401 of the fan module 4 to quickly and accurately connect with the interface 301 on the power module 3 along the guide channel. The entire process is convenient and quick, requiring no complex operations to complete the installation, facilitating chassis assembly and daily maintenance.
[0026] Furthermore, such as Figure 3 As shown, in order to further improve the accuracy of the connection between the connector 401 on the fan module 4 and the interface 301 on the power module 3, the inner wall of the housing 5 is provided with a limiting rib 501 arranged along the connection direction between the fan module 4 and the guide channel, and the fan module 4 is provided with a limiting recess 402 that can slide and cooperate with the limiting rib 501, so as to guide the connector 401 on the fan module 4 and the interface 301 on the power module 3 to be accurately connected.
[0027] The above, such as Figure 1 , Figure 2 As shown, the housing 5 is provided with honeycomb heat dissipation holes 502 corresponding to the fan module 4, so that the fan module 4 can guide the heat inside the box structure to the outside.
[0028] It should be noted that in this technical solution, if... Figure 2As shown, there are two fan modules 4, one of which guides air from the external environment into the box-shaped structure, while the other fan module 4 guides air from the box-shaped structure into the external environment. Simultaneously, multiple boards 201 are sandwiched between the two fan modules 4, with gaps between adjacent boards 201 to allow airflow, thus forming a unidirectional airflow path to increase the heat dissipation efficiency of the boards 201, power module 3, and other structures.
[0029] In this embodiment, when the connector 401 on the fan module 4 can move along the guide channel to be inserted into the interface 301 on the power module 3, one end of the fan module 4 is flush with the front panel 2, and a hand-tightening bolt 403 that can be threaded into the housing 5 or the front panel 2 is provided on the side of the fan module 4 that is flush with the front panel 2. This is to fix the position of the fan module 4 after the connector 401 on the fan module 4 is inserted into the interface 301 on the power module 3, and to ensure the stability of the electrical connection between the fan module 4 and the power module 3.
[0030] Furthermore, in this technical solution, to facilitate the assembly and disassembly of the entire box structure, the shell 5 and the front panel 2, and the rear panel 1 and the shell 5 can be detached and connected by fastening bolts. Example 2
[0031] like Figures 1-4 As shown, based on Embodiment 1, a handle 6 is provided on the housing 5 and / or the rear panel 1 to facilitate handling by the operator. Meanwhile, the front panel 2 is provided with indicator lights and switches corresponding to the working status of the board 201, so that the operator can intuitively understand the working status of the board 201.
[0032] Working principle: A fan mounting position 205 is reserved between the front panel 2 and the end opening of the housing 5, and the edge of the board 201 forms a guide channel with the inner wall of the housing 5, so that the fan module 4 can be accurately inserted along the guide channel during installation, reducing the installation difficulty of the fan module 4 and improving the disassembly and assembly efficiency of the fan module 4. At the same time, the connector 401 for connecting the fan module 4 is integrated into the power supply module 3, so that the connector 401 of the fan module 4 can be quickly and accurately plugged into the interface 301 on the power supply module 3 along the guide channel. The whole process is convenient and quick, and the installation can be completed without complicated operations, which facilitates the assembly and daily maintenance of the chassis.
[0033] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
