[0002] In the existing controller, in order to facilitate the layout of various electronic components, all electronic components are usually installed on a PCB board. As a result, the overall size of the controller is large, which increases the installation conditions of the controller and is inconvenient for the installation of the controller. In addition, since all electronic components are installed on a PCB board, the mass of the PCB board is large. In order to facilitate the staff to assemble and repair the controller, it is necessary to set a guide rail on the shell of the controller to assist and guide the PCB board when loading and unloading the PCB board, so as to reduce the difficulty of the staff to assemble and repair the controller. However, this will increase the manufacturing cost of the controller. For this reason, there is an urgent need for a small controller that is easy to install, can reduce the size, make the structure more compact, and reduce the production cost. Utility Model Content

[0005] With the above structure, the electronic components can be installed on the first circuit board and the second circuit board respectively, and then the first circuit board and the second circuit board are connected by plugging and unplugging through the first electrical connector and the second electrical connector, so that the first circuit board and the second circuit board are electrically connected. Therefore, it is not necessary to install all the electronic components on a large circuit board, but only to install the electronic components on the first circuit board and the second circuit board of smaller size, so that the size of the small controller can be reduced and the structure of the small controller can be more compact.
[0006] In addition, by providing the first circuit board and the second circuit board, the electronic components are installed on the first circuit board and the second circuit board respectively, so that all the electronic components can be avoided from being concentrated on one circuit board, so that the weight of the first circuit board and the second circuit board is small, so that it is convenient for the staff to install the first circuit board and the second circuit board, and the difficulty of assembly and maintenance is reduced. At the same time, since the weight of the first circuit board and the second circuit board is small, it is not necessary to set a guide rail in the shell to assist the installation of the circuit board.

[0016] With the above structure, by arranging the third connection terminal at a position close to the second module on the panel, when repairing the small controller, it is only necessary to remove the heat sink corresponding to the second circuit board, and then the second module and the third connection terminal can be in the open position after the heat sink is removed. This makes it convenient for the staff to repair the small controller.
[0017] In some embodiments, the second module is a communication module, the third connection terminal is an SMA terminal, one end of the third connection terminal inside the housing is electrically connected to the second module through a wire, and one end of the third connection terminal outside the housing is used to connect to an antenna.
[0018] With the above structure, when the communication module and the SMA terminal need to be repaired, it is only necessary to remove the heat sink corresponding to the second circuit board, so that the communication module and the SMA terminal are in the open position after the heat sink is removed.

In addition, in one or more embodiments, the particular features, structures, or characteristics can be combined in any appropriate manner, as will be apparent to one of ordinary skill in the art from this disclosure.
[0032] Below, in conjunction with the accompanying drawings, the specific structure of each embodiment of the small and medium controller 10 of the present application is described in detail.
[0033] Figure 1 This is a schematic diagram of the three-dimensional structure of the small controller 10 in the embodiment of the present application; Figure 2 for Figure 1 An exploded schematic diagram of the small and medium-sized controller 10. Figure 1 , Figure 2 As shown, the small controller 10 in the present application includes a housing 100, a first circuit board 200 and a second circuit board 300. The first circuit board 200 is installed in the housing 100, and a first electrical connector (not shown) is provided on the first circuit board 200. A second electrical connector (not shown) is provided on the second circuit board 300, and the second electrical connector is pluggably connected to the first electrical connector.
[0034] As described above, the electronic components can be mounted on the first circuit board 200 and the second circuit board 300 respectively, and then the first circuit board 200 and the second circuit board 300 are plugged and connected through the first electrical connector and the second electrical connector, so that the first circuit board 200 and the second circuit board 300 are electrically connected. Therefore, it is not necessary to mount all the electronic components on a large circuit board, but only to mount the electronic components on the first circuit board 200 and the second circuit board 300 of smaller size, so that the size of the small controller 10 can be reduced, and the structure of the small controller 10 can be made more compact.
[0035] In addition, by providing the first circuit board 200 and the second circuit board 300, the electronic components are installed on the first circuit board 200 and the second circuit board 300 respectively, so that all the electronic components can be avoided from being concentrated on one circuit board, so that the weight of the first circuit board 200 and the second circuit board 300 is relatively small, so that it is convenient for the staff to install the first circuit board 200 and the second circuit board 300, and the difficulty of assembly and maintenance is reduced. At the same time, since the weight of the first circuit board 200 and the second circuit board 300 is relatively small, it is not necessary to provide a guide rail in the housing 100 to assist the installation of the circuit board. As a result, the structure of the housing 100 can be simplified, thereby reducing the production cost of the small controller 10.
[0036] like Figure 2 As shown, in some embodiments, the first circuit board 200 and the second circuit board 300 are arranged in parallel, the first circuit board 200 is provided with a first connection terminal 210, the second circuit board 300 is provided with a second connection terminal 310, and the first connection terminal 210 and the second connection terminal 310 are respectively arranged on two opposite surfaces of the first circuit board 200 and the second circuit board 300. Thus, by making the first circuit board 200 and the second circuit board 300 arranged in parallel, and respectively arranging the first connection terminal 210 and the second connection terminal 310 on two opposite surfaces of the first circuit board 200 and the second circuit board 300, the distance between the first circuit board 200 and the second circuit board 300 can be reduced during installation. Thus, the space required for installing the first circuit board 200 and the second circuit board 300 can be reduced, and the structure of the small controller 10 can be made more compact, and the volume of the housing 100 and the small controller 10 can be reduced.
[0037] like Figure 2 As shown, in some embodiments, the first connection terminal 210 and the second connection terminal 310 are respectively arranged at the edge of the same side of the first circuit board 200 and the second circuit board 300. Therefore, by arranging the first connection terminal 210 and the second connection terminal 310 at the edge of the same side of the first circuit board 200 and the second circuit board 300, the first circuit board 200 and the second circuit board 300 can be connected to other devices on the same side, so that the installation and connection of the small controller 10 can be facilitated.
[0038] like Figure 2As shown, in some embodiments, a first module (not shown) is disposed on the first circuit board 200, and a second module 320 is disposed on the second circuit board 300, and the first module and the second module 320 are respectively disposed on two opposite surfaces of the first circuit board 200 and the second circuit board 300. The housing 100 includes a heat sink 110, and two heat sinks 110 are disposed in parallel. The first circuit board 200 and the second circuit board 300 are located between the two heat sinks 110, and the first module and the second module 320 are respectively connected to the corresponding heat sinks 110 by thermal conduction. Therefore, by respectively arranging the first module and the second module 320 on two opposite surfaces of the first circuit board 200 and the second circuit board 300, it is possible to avoid obstruction between the first circuit board 200 and the second circuit board 300, thereby reducing the distance between the first circuit board 200 and the second circuit board 300, making the structure of the small controller 10 more compact, so as to reduce the volume of the small controller 10.
[0039] like Figure 2 As shown, in some embodiments, the two heat dissipation plates 110 have the same shape. Thus, by making the two heat dissipation plates 110 on both sides have the same shape, the number of molds for producing the heat sink is reduced, thereby reducing the production cost.
[0040] like Figure 2 As shown, in some embodiments, the housing 100 further includes a panel 120, and a plurality of panels 120 are provided, which are fixedly connected to the heat sink 110 around the edges of the two heat sinks 110. A third connection terminal 121 is provided on one panel 120, and the third connection terminal 121 is electrically connected to the second module 320, and the third connection terminal 121 is provided at a position close to the second module 320 on the panel 120. Thus, by providing the third connection terminal 121 at a position close to the second module 320 on the panel 120, when the small controller 10 is repaired, it is only necessary to remove the heat sink 110 corresponding to the second circuit board 300, so that the second module 320 and the third connection terminal 121 are in an open position after the heat sink 110 is removed. Thus, it is convenient for the staff to repair the small controller 10.
[0041] like Figure 2 As shown, in some embodiments, the second module 320 is a communication module, the third connection terminal 121 is an SMA terminal, one end of the third connection terminal 121 inside the housing 100 is electrically connected to the second module 320 through a wire, and one end of the third connection terminal 121 outside the housing 100 is used to connect an antenna. Therefore, when the communication module and the SMA terminal need to be repaired, it is only necessary to remove the heat sink 110 corresponding to the second circuit board 300, so that the communication module and the SMA terminal are in the open position after the heat sink 110 is removed. Therefore, it is convenient for the staff to perform maintenance.
[0042] like Figure 2 As shown, in some embodiments, the heat sink 110 and the panel 120 are rectangular, and four panels 120 are provided and fixed around the edges of the four sides of the two heat sinks 110, so that the housing 100 forms a rectangular parallelepiped.
[0043] like Figure 2 As shown, in some embodiments, a through-hole-shaped connection port 122 is provided on the panel 120 at a position corresponding to the first connection terminal 210 and the second connection terminal 310, and the first connection terminal 210 and the second connection terminal 310 are exposed through the connection port 122. Therefore, by providing the connection port 122 on the panel 120, it is convenient to connect to the first connection terminal 210 and the second connection terminal 310 through the connection port 122.
[0044] like Figure 2 As shown, in some embodiments, the connection port 122 and the third connection terminal 121 are located on two different panels 120. Therefore, by arranging the connection port 122 and the third connection terminal 121 on two different panels 120, the connection port 122 and its corresponding first connection terminal 210, second connection terminal 310 and third connection terminal 121 can be separated, so as to avoid the first connection terminal 210 and the second connection terminal 310 from affecting the third connection terminal 121 after being connected to other devices.
[0045] The above contents, combined with Figure 1 , Figure 2 The possible embodiments of the small and medium-sized controller 10 of the present application are described by way of example.

The housing 100 is in the shape of a rectangular parallelepiped, including a square heat sink 110 arranged on the left and right sides and panels 120 located on the upper, lower, left and right sides. The two heat sinks 110 have the same shape and are arranged opposite to each other in a parallel state. The four panels 120 are arranged around the four sides of the heat sink 110 and are fixed to the four end faces of the two heat sinks 110 by bolts to form a rectangular shell-like component for mounting and accommodating the first circuit board 200 and the second circuit board 300.
[0047] like Figure 2As shown, the first circuit board 200 and the second circuit board 300 are in the shape of square plates, and the first circuit board 200 and the second circuit board 300 are located between the two heat sinks 110 and are arranged parallel to the heat sinks 110. A first electrical connector is arranged on the right side of the first circuit board 200, and a second electrical connector is arranged on the left side of the second circuit board 300. After the first electrical connector and the second electrical connector are plugged in and out, the first circuit board 200 and the second circuit board 300 can be electrically connected.
[0048] like Figure 2 As shown, a first module (not shown) and a first connection terminal 210 are provided on the first circuit board 200. The first module may be a processor module, a storage module or other modules required by the small controller 10. A plurality of first connection terminals 210 are provided, namely, an HDMI connection terminal, a USB connection terminal and a LAN connection terminal. The plurality of first connection terminals 210 are arranged in a vertical direction along the front edge of the first circuit board 200. The first module and the first connection terminal 210 are all provided on the left side surface of the first circuit board 200 to avoid increasing the distance between the first circuit board 200 and the second circuit board 300 due to the excessive size of the first module or the first connection terminal 210, thereby affecting the connection between the first electrical connector and the second electrical connector.
[0049] like Figure 2 As shown, the second circuit board 300 is provided with a second module 320 and a second connection terminal 310, and the first module can be a 5G / 4G module or a WIFI module.

The first module and the first connection terminal 210 are all arranged on the right side surface of the second circuit board 300 to avoid increasing the distance between the first circuit board 200 and the second circuit board 300 due to the excessive size of the second module 320 or the second connection terminal 310, thereby affecting the connection between the first electrical connector and the second electrical connector.
[0050] like Figure 2 As shown, the panel 120 located on the front side is provided with a through-hole-shaped connection port 122 at a position corresponding to the first connection terminal 210 and the second connection terminal 310. After installation, the end surfaces of the first connection terminal 210 and the second connection terminal 310 can be exposed from the connection port 122 to facilitate connection with other devices.
[0051] like Figure 2As shown, a third connection terminal 121 is also provided on the upper panel 120. The third connection terminal 121 is an SMA terminal.

The third connection terminal 121 is located between the second circuit board 300 and the right heat sink 110 on the panel 120. Therefore, when repairing the second module 320 and the third connection terminal 121, it is only necessary to remove the right heat sink 110 to place the second module 320 and the third connection terminal 121 in an open position, so as to facilitate maintenance and replacement by the staff.

After the second circuit board 300 is connected to the first circuit board 200 by the first electrical connector and the second electrical connector, the second circuit board 300 can be fixed to the first circuit board 200 or directly fixed to the left heat sink 110 by bolts, so that the first circuit board 200 and the second circuit board 300 can be kept fixed. Then, four panels 120 are respectively fixed around the end surface of the left heat sink 110 by bolts, and the panels 120 are fixed to the left heat sink 110. Finally, the right heat sink 110 is fixed to the panel 120 by bolts, and a thermal conductive silicone gasket is arranged between the second module 320 and the three right plates, so that the two sides of the thermal conductive silicone gasket are respectively fitted with the second module 320 and the heat sink 110 to facilitate the second module 320 to transfer heat to the heat sink 110.
