DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following clearly and completely describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained based on the embodiments of the present application without the need for creative efforts by those skilled in the art are all within the scope of protection of the present application.

[0033] The terms used in the embodiment section of this application are used only to interpret specific examples of the application, and are not intended to limit the application.

[0034] For ease of understanding, the relevant technical terms in the embodiments of the present application will first be explained and explained.

[0035] Strong electricity is primarily intended to provide power, and the power provided by strong electricity may be understood as electricity that can cause household electrical appliances to emit light, generate heat, move, etc. For example, light bulbs, water heaters, motors, etc. all require strong electricity.

[0036] The weak current is mainly for providing signals, and the signals provided by the weak current may be understood as information such as voice, data, images, etc. For example, a wireless AP device in a home can transmit signals through a network, a doorbell in a home can transmit voice, a television can transmit images, etc.

[0037] Here, strong electricity can operate independently, but weak electricity generally cannot operate independently and requires power from strong electricity. For example, a light bulb can emit light when powered, but a wireless AP device cannot operate normally with just a communication cable (e.g., a LAN cable) and must be powered before it can be used.

[0038] The distinction between strong and weak electricity should be made based not only on the magnitude of the voltage but also on the application. For network access devices such as wireless AP devices, voltages greater than 36V may be called strong electricity, and voltages less than or equal to 12V may be called weak electricity. Strong electricity in the embodiments of the present application may include AC strong electricity, for example, 220V AC power, and also includes Ethernet power supply (abbreviated as Power over Ethernet, PoE), for example, 48V DC power supplied by PoE.

[0039] It should be noted that there may be a certain deviation in the classification of low-power network access devices such as wireless AP devices depending on the manufacturer, for example, a voltage of 24V or less may be called low-power. In this application, there is no particular limitation on the classification of low-power network access devices such as wireless AP devices.

[0040] Junction temperature refers to the actual temperature of a chip (wafer, die) in an electronic device, and may be expressed as Tj. It is generally higher than the temperature of the chip's packaging case. The temperature of the chip's packaging case may be expressed as Tc. The junction temperature can evaluate the time and thermal resistance required for heat dissipation from the chip to the device's packaging case, and the lower the chip's junction temperature, the better.

[0041] After a chip (wafer, die) in an electronic device operates and generates heat, the environmental temperature where the chip is located in the electronic device may be represented as Ta.

[0042] As described in the background art, embedded wireless AP devices have the advantages of beautiful installation and space saving, and are therefore widely applied in people's daily life and work.

[0043] The pain points of users in the conventional embedded wireless AP device are mainly in the performance and operation and maintenance of the whole device. The conventional embedded wireless AP device has an integrated structure, and the embedded wireless AP device is entirely installed in a terminal box of a wall. Due to the limitation of the thickness of the wall and the size of the terminal box, the volume of the conventional embedded wireless AP device is small, so that when the embedded wireless AP device is operating, the heat generated from the internal circuit board assembly is difficult to be discharged, which seriously affects the heat dissipation performance of the conventional embedded wireless AP device.

[0044] It should be understood that for an embedded wireless AP device, when the same hardware is configured, the higher the heat dissipation performance, the higher the performance of the entire device. Accordingly, when the heat dissipation performance is low, a temperature control policy is formulated based on the maximum temperature that the circuit board assembly can withstand, and the speed of the entire embedded wireless AP device is limited. At this time, the performance of the entire device of the conventional embedded wireless AP device is affected and it cannot perform its functions better.

[0045] In addition, when a high-voltage failure occurs in the conventional embedded wireless AP device (for example, the function of changing high voltage to low voltage fails due to damage to the power module of the circuit board assembly), the conventional embedded wireless AP device needs to be completely removed from the terminal box. Since the conventional embedded wireless AP device uses electrical connections with both the power cable and the communication cable in the terminal box, the process of completely removing the conventional embedded wireless AP device is complicated and requires on-site repair by a professional operation and maintenance technician, which makes the operation and maintenance of the conventional embedded wireless AP device difficult.

[0046] Therefore, in order to solve the problem of the high difficulty of operation and maintenance of the conventional built-in wireless AP device, the related art proposes the installation of a separate built-in wireless AP device, in which the main device and the mounting bracket of the separate built-in wireless AP device are installed separately, and the mounting bracket is installed inside the wall. The power module of the separate built-in wireless AP device is located in the mounting bracket and electrically connected to the power cable (e.g., neutral line and live line) in the terminal box, and the mounting bracket is inserted into the main device through a Type-C interface.

[0047] However, the above-mentioned separate type built-in wireless AP device still has certain defects in terms of operation and maintenance, which will be described in detail below.

[0048] For a separate type embedded wireless AP device, the power module is located in the mounting bracket and is mainly used to convert the strong AC power (e.g., 220V AC power) input from the power cable into weak DC power (e.g., 12V DC power) and then transmit it to the main device via the Type-C interface. If a strong power failure occurs in the mounting bracket (e.g., damage to the power module), a professional operation and maintenance technician will be required to visit and repair the device, which makes the operation and maintenance of the separate type embedded wireless AP device very difficult.

[0049] In addition, when the power supply module of the separate type embedded wireless AP device in the related art operates, a lot of heat is generated, which causes the heat generation of the mounting bracket to be large. Because the mounting bracket is attached to the wall, the heat of the mounting bracket is difficult to dissipate, which affects the heat dissipation performance of the entire separate type embedded wireless AP device, and limits the performance of the entire embedded wireless AP device.

[0050] Therefore, the embodiments of the present application provide a network access device, and by improving the structure of the network access device, the difficulty of operation and maintenance of the network access device can be reduced, and there is no need for professional operation and maintenance personnel to visit and repair the network access device, thereby not only solving the defects existing in the conventional embedded wireless AP device, but also improving the heat dissipation performance of the network access device.

[0051] The network access device may include a wireless network access device or a wired network access device, where the wireless network access device may include a wireless AP device or other wireless device capable of providing a network signal to the electronic devices mentioned above.

[0052] Hereinafter, taking a wireless AP device as an example, the structure of the network access device of the present application will be further described with reference to the drawings.

[0053] 1 and 2 are schematic diagrams showing the assembly of the network access device 100 on a wall from different angles. Here, in order to easily observe the assembly of the network access device 100 on the terminal box 200, FIG. 2 shows a cross-sectional view of the terminal box 200 in the AA direction in FIG. 1.

[0054] 1 and 2, a network access device 100 includes a terminal block 1 and a device body 2, and the terminal block 1 is configured to be mounted in a wall and electrically connected to cables in the wall, thereby realizing mounting of the device body 2 in the wall. The cables in the wall may include a power cable and a communication cable. The communication cable may include a LAN cable. The terminal block 1 may be fixed in the wall by fasteners, locks, or other methods. The fasteners may include, but are not limited to, screws, bolts, etc.

[0055] 1 and 2 are schematic diagrams showing the assembly of the network access device 100 on the terminal box 200 on the wall from different angles. Here, in order to easily observe the assembly of the network access device 100 on the terminal box 200, FIG. 2 shows a cross-sectional view of the terminal box 200 in FIG. 1 in the AA direction.

[0056] 1 and 2, the terminal block 1 may be further configured to be mounted in a terminal box 200 in a wall and electrically connected to a cable in the terminal box 200, thereby realizing the mounting of the device main body 2 in the wall and realizing the electrical connection between the terminal block 1 and the cable. The terminal box 200 may be understood as a hidden box that is embedded in the wall in advance when interior construction work is performed, and the cables required for the network access device 100 can be electrically connected.

[0057] FIG. 3 shows an exploded view of the network access device 100. Referring to FIG. 3, the device body 2 may be understood as a part of the network access device 100 other than the terminal block 1. There is a circuit board assembly (not shown) in the device body 2, and the circuit board assembly includes a power supply board (not shown). The device body 2 is inserted into the terminal block 1 to conduct the power supply board and the cable. The terminal block 1 is attached to a wall and electrically connected to the cable, and when the device body 2 is inserted into the terminal block 1, the device body 2 can be attached to the wall via the terminal block 1, thereby realizing the assembly of the network access device 100 on the wall.

[0058] The terminal block 1 is mounted in a wall (e.g., a terminal box 200) and can be hidden in the wall, which facilitates electrical connection between the terminal block 1 and the cable, and ensures that the overall appearance of the network access device 100 is simple and highly integrated with the indoor environment. Therefore, the network access device 100 has the advantages of being beautifully mounted and not taking up much space.

[0059] At the same time, a circuit board assembly is installed in the device body 2, so that the device body 2 has the function of the network access device 100. When the device body 2 is inserted into the terminal block 1, the access device 100 can provide wireless network signals to electronic devices such as mobile phones, tablet computers, smart wearable devices, and computers, and ensure the normal use of these electronic devices. The smart wearable devices may include, but are not limited to, smart watches and virtual reality devices (abbreviated as VR).

[0060] Compared with the separate-type embedded wireless AP device mentioned above, the embodiment of the present application installs a power supply board in the circuit board assembly, and when the device main body 2 and the terminal block 1 are inserted, the power supply board and the cable are electrically connected, so that the strong voltage input from the cable can be relayed to the power supply board of the device main body 2, and the power supply board can provide electrical energy to other parts of the circuit board assembly.

[0061] In addition, since the power supply board is installed inside the device body 2, when a high-voltage failure occurs and operational maintenance is required, the user can complete removal of the device body 2 and terminal block 1 simply by pulling out the device body 2 from inside the terminal block 1, and then mail the device body 2 to the manufacturer of the network access device 100 for repair. When the user receives the repaired device body 2 or a new device body 2, the user can replace it by himself, and it can be used continuously by simply inserting it directly into the terminal block 1.

[0062] Compared with the above-mentioned embedded wireless AP device and separate embedded wireless AP device, the network access device 100 of the present application does not require a professional operation and maintenance technician to visit for repair when a high-voltage fault occurs, which reduces the difficulty of operation and maintenance of the network access device 100, improves the convenience of after-sales service for the network access device 100, and improves the user experience.

[0063] Furthermore, compared to the separate built-in wireless AP device mentioned above, since the circuit board assembly is the main heat source of the network access device 100, the present application has the circuit board assembly located within the device itself, thereby concentrating the heat source of the network access device 100 within the device body 2 and avoiding excessive heat generation when the terminal block 1 is in operation. Therefore, the embodiment of the present application can improve the heat dissipation performance of the network access device 100 and the performance of the entire device, so that the network access device 100 has the characteristics of high heat dissipation and excellent performance of the entire device.

[0064] In addition, the terminal block 1 is mounted in the wall, but when the device body 2 is inserted into the terminal block 1, the device body 2 can be exposed to the surface of the wall, so that the volume of the device body 2 is not limited by the thickness of the wall and the size of the terminal box 200. Therefore, the volume of the device body 2 and the available space of the circuit board assembly in the device body 2 can be increased according to the actual needs during design, which helps the circuit board assembly to dissipate heat. Compared with the conventional embedded wireless AP device mentioned above, the network access device 100 in the embodiment of the present application has better heat dissipation performance.

[0065] There is a heat dissipation hole 21 on the device body 2, which is located outside the terminal block 1, so that the heat of the circuit board assembly can be dissipated to the outside of the device body 2 through the heat dissipation hole 21, further improving the heat dissipation performance of the network access device 100 and the performance of the entire equipment.

[0066] Continuing to refer to FIG. 3, the number of heat dissipation holes 21 may be multiple, and the multiple heat dissipation holes 21 may be uniformly distributed on the top 22 and / or at least one side wall of the device body 2, so that the air inside the device body 2 can convect with the air outside the device body 2 through the multiple heat dissipation holes 21, further improving the heat dissipation performance of the network access device 100 and the performance of the entire device.

[0067] It should be noted that in some embodiments, besides the top 22 and / or sidewall of the device body 2, the heat dissipation holes 21 may also be distributed on the bottom 23 of the device body 2, thereby further improving the heat dissipation performance of the network access device 100 and the performance of the entire device. The heat dissipation holes 21 may be circular holes, elongated holes, square holes or other shapes of openings, and the present application is not particularly limited on the shape and installation position of the heat dissipation holes 21.

[0068] 4, there is a terminal board (not shown) in the terminal block 1 that is inserted into the power supply board, and there is an electrical connector 11 on the terminal board that is exposed on the surface of the terminal block 1. Here, the electrical connector 11 includes a power cable connector 111 that is configured to be electrically connected to a power cable in a cable. When the device main body 2 is inserted into the terminal block 1, the power supply board and the power cable are electrically connected via the power cable connector 111, so that a strong AC voltage (e.g., 220V AC power) output from the power cable is relayed to the power supply board via the power cable connector 111, and thus the power supply board can meet the power supply demand of other devices other than the power supply board in the circuit board assembly.

[0069] Here, the circuit board assembly may further include a main board (not shown), which may be understood as a control circuit board for controlling and handling each function of the network access device 100 in the device body 2. Many electronic devices may be mounted on the main board, and the electronic devices may include chips and electronic elements. Exemplarily, the chips mounted on the main board may include, but are not limited to, a central processor (abbreviated as Central Processing Unit, CPU), a data transmission physical layer chip (abbreviated as Physical Layer Chip, PHY), a double data rate (abbreviated as Double Data Rate, DDR) memory, a flash memory (abbreviated as flash), an Ethernet (abbreviated as Media Access Control, MAC) chip, and the like. The electronic elements may include, but are not limited to, a capacitor, a resistor, and the like. The capacitor may include, but is not limited to, an electrolytic capacitor (abbreviated as CD). For the functions and connections of these electronic devices on the main board, reference may be made to the relevant description of the conventional wireless AP device, and the description will be omitted here.

[0070] It should be clarified that the main board may be a single-layer circuit board, or a laminated two-layer or multi-layer circuit board, and the present application does not place any particular limitation on the structure of the main board.

[0071] By connecting the main board to the power supply board, the power supply board can be connected to the electronic device mounted on the main board, thereby providing electrical energy to the electronic device mounted on the main board to meet the power consumption demand of the electronic device on the main board, thereby providing the device body 2 with the functionality of a network access device 100.

[0072] In some embodiments, the main board may be connected to the power board by a flexible circuit board, a frame-shaped circuit board with pads on its surface and metal via holes inside, or other methods, and this application is not particularly limited to the method of connection between the main board and the power board.

[0073] In some embodiments, when the main board is conductive to the power supply board via a frame-shaped circuit board, the main board may be stacked on the side of the power supply board away from the terminal block 1 to form a circuit board assembly having at least two layers, thereby saving the projection area on the wall of the device body 2 and reducing the mounting space on the wall of the device body 2.

[0074] In some embodiments, if there is no particular requirement for the mounting space on the wall of the device body 2, the main board may further be integrated with the power supply board into one circuit board to form a circuit board assembly. The embodiments of the present application do not particularly limit the structure of the circuit board assembly.

[0075] The structure of the network access device 100 will be further described below by taking an example in which a main board is stacked on a circuit board.

[0076] 3, there is a power module (not shown) on the power board. When the power board is inserted into the terminal board, the power module is configured to be conductive to the power cable via the power cable connector 111 and convert the strong AC voltage input from the power cable into weak DC voltage to meet the power consumption demand of the electronic devices on the main board. Here, the strong AC voltage input from the power cable may be 220V AC power. The power module can convert the strong AC voltage of 220V into 12V or other weak DC voltage to meet the power consumption demand of various electronic devices on the main board. In the embodiment of the present application, there is no particular limitation on the voltage of the weak DC voltage converted by the power module.

[0077] Here, the power supply module has a positive electrode and a negative electrode that are conductive to the power cable connector 111, so that the power supply module can be electrically connected to the neutral and live wires of the power cable via the power cable connector 111, thereby accepting high AC current input from the power cable.

[0078] 4 shows a structural schematic diagram of the terminal block 1. Referring to FIG. 4, there may be two power cable connectors 111, one of which is a positive connector and the other is a negative connector. The positive pole of the power module may be electrically connected to the live line of the power cable through the positive connector, and the negative pole of the power module may be electrically connected to the neutral line of the power cable through the negative connector, thereby realizing the conduction between the power module and the power cable.

[0079] In some embodiments, when the power module is input with high AC power, the distance between the positive and negative poles of the power module meets the requirements of the safety standard distance (abbreviated as the regulated distance). The regulated distance may be understood as the minimum safety standard distance between the positive and negative poles of the power module. Some standards stipulate that when the power module is input with high AC power, the regulated distance between the positive and negative poles of the power module is 3.6 mm. The measurement standard for the distance between the positive and negative poles may refer to the measurement standard stipulated in the conventional regulated distance, and the description here is omitted. The distance between the positive and negative poles of the power module in the embodiment of the present application is equal to or greater than the regulated distance between the positive and negative poles, so that the power module and the network access device 100 have reliability and safety during operation. For example, the distance between the positive and negative poles of the power module may be 3.6 mm, 3.7 mm, 3.8 mm, etc., and the present application does not particularly limit the distance between the positive and negative poles of the power module, and the distance between the positive and negative poles of the power module may be equal to or greater than the regulated distance between the positive and negative poles.

[0080] Continuing to refer to FIG. 4, the electrical connector 11 may further include a communication cable connector 112, which is configured to be electrically connected to a communication cable in a cable, so that when the device main body 2 is inserted into the terminal block 1, a network input signal of the communication cable can be relayed to the power supply board via the communication cable connector 112, and further relayed to the main board via the power supply board, so that the main board can output a network signal after processing the network input signal, for use by the electronic device.

[0081] In some embodiments, the communication cable connector 112 and the power cable connector 111 are held on the terminal block 1. By holding the communication cable connector 112 and the power cable connector 111 on the terminal block 1, it is possible to avoid a direct electrical connection of the device main body 2 via the communication cable connector 112 and the power cable connector 111. When it is necessary to remove the device main body 2, it may be directly pulled out from above the terminal block 1, and there is no need to operate the communication cable connector 112 and the power cable connector 111.

[0082] 4, the communication cable connector 112 may be exposed on the top surface of the terminal block 1, and the power cable connector 111 may be exposed on a side surface of the terminal block 1. Alternatively, the communication cable connector 112 and the power cable connector 111 may be simultaneously exposed on the side surface or other positions of the terminal block 1. In the present application, there is no particular limitation on the exposed positions of the communication cable connector 112 and the power cable connector 111 on the terminal block 1.

[0083] Also, referring to FIG. 1, at least a portion of the terminal block 1 is fitted into a wall, and the electrical connector 11 is exposed on the side of the terminal block 1 facing the cable to electrically connect the electrical connector 11 to the power cable and the communication cable in the cable, while at least a portion of the terminal block 1 can be hidden in the wall (e.g., the terminal box 200 in the wall), thereby providing the network access device 100 with the advantages of being beautifully installed and not taking up space.

[0084] 1 shows a structure in which the terminal block 1 is entirely fitted in a terminal box 200 in a wall. In some other embodiments, only a portion of the terminal block 1 provided with the electrical connector 11 may be fitted in the terminal box 200, and at this time, a portion of the terminal block 1 may be fitted in the wall. Compared with a mode in which only a portion of the electrical connector 11 of the terminal block 1 is fitted in the terminal box 200, when the terminal block 1 is entirely fitted in the terminal box 200, the terminal block 1 is completely hidden in the terminal box 200, and the thickness of the network access device 100 exposed outside the wall surface can be reduced, so that the network access device 100 is lighter and more aesthetically pleasing.

[0085] The structure of the network access device 100 will be further described below by taking as an example a case in which the terminal block 1 is entirely fitted into a terminal box 200.

[0086] Continuing to refer to FIG. 4, the electrical connector 11 of the terminal block 1 is provided with a first bypass opening 12, and the electrical connector 11 is exposed through the first bypass opening 12 to facilitate electrical connection between the electrical connector 11 and the terminal box 200.

[0087] When the communication cable connector 112 and the power cable connector 111 are far apart in the terminal block 1, one first escape port 12 may be provided at each of the locations corresponding to the communication cable connector 112 and the power cable connector 111 of the terminal block 1. The shape of the first escape port 12 is adapted to (is the same as or similar to) the shape of the corresponding communication cable connector 112 or the power cable connector 111, so that the communication cable connector 112 or the power cable connector 111 can be exposed to the surface of the terminal block 1 through the corresponding first escape port 12.

[0088] A first escape hole 12 is provided at each of the positions corresponding to the positive and negative connectors of the terminal block 1, ensuring that both the positive and negative connectors are exposed on the surface of the terminal block 1 and reducing the number of openings on the terminal block 1.

[0089] In some embodiments, when the communication cable connector 112 and the power cable connector 111 are close to each other, the communication cable connector 112 and a part of the power cable connector 111 may share one first escape port 12. In the embodiments of the present application, there is no particular limitation on the shape and installation position of the first escape port 12.

[0090] Figure 5 shows a structural schematic diagram of two first adapters 3. Figure 6 shows a structural schematic diagram of two second adapters 4. With reference to Figures 5, 6 and 4 together, the network access device 100 further includes at least one adapter assembly (not shown), which includes a first adapter 3 and a second adapter 4. The number of adapter assemblies may be one or more than two as shown in Figures 5 and 6, and the embodiment of the present application is not particularly limited to the number of adapter assemblies.

[0091] 5, 6 and 3, the first adapter 3 is located on the power supply board and exposed on the surface of the device body 2. For example, the first adapter 3 and the power supply module may both be located on the surface of the power supply board facing the second adapter 4. The second adapter 4 is located on the terminal board and exposed on the surface of the terminal block 1. The first adapter 3 and the second adapter 4 are inserted into each other to conduct the terminal board and the power supply board, realizing the insertion of the device body 2 and the terminal block 1, and the power supply board can be conducted to the cable via the adapter assembly and the terminal board, so that the high AC voltage input from the power cable in the cable can be relayed to the power supply board via the terminal board and the adapter assembly. The connection between the device body 2 and the terminal block 1 can be realized by the adapter assembly.

[0092] 6 and 5, the second adapter 4 has an insertion part 41 on it, and the first adapter 3 has a socket 31 at a position corresponding to the insertion part 41. At least a part of the insertion part 41 is inserted into the socket 31 and is conductive to the socket 31 to realize the mutual insertion of the first adapter 3 and the second adapter 4, and to realize the transmission of AC power and network input signals between the insertion part 41 and the socket 31, thereby establishing electrical continuity between the terminal board and the power supply board. For the structure and conduction principle of the insertion part 41 and the socket 31, reference may be made to the relevant description of the conventional plug-and-play adapter, and the description will be omitted here.

[0093] The electrical connector 11 is electrically connected to at least one insertion part 41. For example, the positive connector and the negative connector may be electrically connected to one insertion part 41, respectively. The communication cable connector 112 may be electrically connected to eight insertion parts 41, thereby fulfilling the transmission of the input signal. The number of insertion parts 41 in the adapter assembly may exceed the total number of insertion parts 41 required when electrically connecting the electrical connector 11. For example, when the adapter assembly is electrically connected to the positive connector, the negative connector, and the communication cable connector 112 at the same time, the number of insertion parts 41 required when electrically connecting the electrical connector 11 is ten, and at this time, the number of insertion parts 41 in the adapter assembly may exceed ten. For example, the number of insertion parts 41 in the adapter assembly may be twelve as shown in FIG. 6, and at this time, two second adapters 4 having six insertion parts 41 may be selected in the adapter assembly. Or, the adapter assembly may have eleven insertion parts 41 or other numbers greater than ten. When an extra number of insertion parts 41 are installed, it is possible to satisfy that different electrical connectors 11 are electrically connected to the corresponding insertion parts 41, and to reserve the extra insertion parts 41 and sockets 31, thereby facilitating adjustment of the corresponding electrical connection positions of the positive connector and the negative connector on the adapter assembly, and ensuring that the distance between the positive pole and the negative pole of the power module can meet the regulated distance requirements when the power module has a high AC power input.

[0094] Compared with the Type-C interface, in the embodiment of the present application, the distance between two adjacent insertion parts 41 in the second adapter 4 is relatively large, which can meet the relay requirements of the adapter assembly for high AC power or other high power (e.g., 48V DC power), and ensure that the high AC power input from the power cable can be transmitted to the power module through the adapter assembly.

[0095] 3, the device body 2 has a second escape opening 241 at a position corresponding to the first adapter 3, and the shape of the second escape opening 241 is adapted to (is the same as or similar to) the shape of the first adapter 3. Exemplarily, the shape of the second escape opening 241 may include, but is not limited to, a rectangle. By providing the second escape opening 241, the first adapter 3 can be exposed to the surface of the device body 2 through the second escape opening 241, and the opening area on the device body 2 can be reduced.

[0096] The terminal block 1 has a third avoidance opening 13 at a position corresponding to the second adapter 4, and the size of the third avoidance opening 13 may be equal to or larger than the size of the second adapter 4, thereby exposing the second adapter 4 to the surface of the terminal block 1 through the third avoidance opening 13 and facilitating the insertion and connection of the second adapter 4 and the first adapter 3.

[0097] 3, there is a protruding mounting part 24 on the side of the device body 2 facing the terminal block 1, and the power supply board is exposed on the surface of the mounting part 24 to facilitate insertion of the power supply board and the terminal board. The mounting part 24 is removably mounted in the terminal block 1. When the network access device 100 is in an operating state, the mounting part 24 is mounted in the terminal block 1, and when a fault occurs in the network access device 100, such as a fault in high-voltage conversion, a fault in the communication main body, or a fault in the control circuit, the mounting part 24 may be removed from the terminal block 1.

[0098] In some embodiments, the second avoidance opening 241 may be installed in a corresponding position facing the second adapter 4 of the mounting portion 24, such that the first adapter 3 can be exposed on the side of the mounting portion 24 facing the second adapter 4 through the second avoidance opening 241, thereby facilitating insertion of the first adapter 3 and the second adapter 4.

[0099] In some embodiments, the shape of the third avoidance opening 13 may be larger than the shape surrounded by the outer contour of the mounting portion 24, and may be adapted (the same as or similar) to the shape surrounded by the outer contour of the mounting portion 24. Exemplarily, the shape surrounded by the outer contour of the mounting portion 24 may include, but is not limited to, a rectangle, and in this case, the shape of the third avoidance opening 13 may also be a rectangle. By setting the contour of the third avoidance opening 13, the mounting portion 24 can be mounted in the terminal block 1 through the third avoidance opening 13, and a removable connection between the mounting portion 24 and the terminal block 1 is realized.

[0100] The end of the terminal block 1 facing the device body 2 may be an open end, and the open end may form a third escape opening 13 .

[0101] In some embodiments, the mounting portion 24 can achieve a detachable connection with the terminal block 1 by a lock, a fastener, or other manner. Exemplarily, the fastener may include, but is not limited to, a screw, a bolt, or other structural member having a connecting function. The embodiments of the present application are not particularly limited to the detachable connection between the mounting portion 24 and the terminal block 1.

[0102] The detachable connection between the mounting portion 24 and the terminal block 1 will be further described below by taking locking as an example.

[0103] 3, a cantilever 25 is connected to a side wall of the mounting portion 24, a first locking portion 251 is provided on the cantilever 25, and the terminal block 1 has a first engagement portion 15 at a position corresponding to the first locking portion 251. When the mounting portion 24 is positioned within the terminal block 1, the first locking portion 251 is elastically locked to the first engagement portion 15. The elastic locking between the first locking portion 251 and the first engagement portion 15 further improves the stability of the connection between the device body 2 and the terminal block 1.

[0104] In some embodiments, the first locking portion 251 is a protrusion, and the first engagement portion 15 is a locking groove that can lock with the protrusion. When the mounting portion 24 is mounted in the terminal block 1, the protrusion can be locked in the locking groove to realize the locking between the first locking portion 251 and the first engagement portion 15. Since the cantilever 25 can be elastically deformed toward or away from the mounting portion 24, when the cantilever 25 is elastically deformed under the action of an external force, the elastic locking between the first locking portion 251 and the first engagement portion 15 can be realized.

[0105] In some other embodiments, the first locking portion 251 is a locking groove, and the first engagement portion 15 is a protrusion. In the embodiments of the present application, the structures of the first locking portion 251 and the first engagement portion 15 are not particularly limited.

[0106] The structure of network access device 100 will be further described below by taking as an example a case where first locking portion 251 is a protrusion and first engagement portion 15 is a locking groove.

[0107] 3, an end of the cantilever 25 remote from the terminal block 1 is exposed to the outer surface of the terminal block 1 to form a biasing end 252. The biasing end 252 is configured to release the elastic lock between the first locking portion 251 and the first engagement portion 15, so that a user can quickly remove the device main body 2 from within the terminal block 1 by pressing the biasing end 252 without the need for an attachment / detachment tool.

[0108] When the user needs to pull out the device body 2 from the terminal block 1, the user may press the biasing end 252, which causes the cantilever 25 to elastically deform toward the mounting portion 24, and during the elastic deformation, the first locking portion 251 comes out of the first engagement portion 15. At this time, the elastic lock between the first locking portion 251 and the first engagement portion 15 is released, and the user can pull out the device body 2 from the terminal block 1.

[0109] When the user needs to install the device body 2 in the terminal block 1, the user may align the mounting portion 24 with the third avoidance opening 13, so that the mounting portion 24 can be installed in the terminal block 1 through the third avoidance opening 13. In the process of installing the mounting portion 24 in the terminal block 1, the side wall of the terminal block 1 presses the cantilever 25, so that the cantilever 25 first elastically deforms toward the mounting portion 24 side to avoid the engagement between the first locking portion 251 and the first engagement portion 15, and ensures that the mounting portion 24 can be installed in the terminal block 1. When the mounting portion 24 is installed in the terminal block 1, the cantilever 25 elastically deforms toward the side away from the mounting portion 24 due to the action of a repulsive force, until the first locking portion 251 is engaged with the first engagement portion 15, completing the installation of the device body 2 in the terminal block 1.

[0110] In some embodiments, the end of the cantilever 25 where the first locking portion 251 is not provided may extend along the side wall of the device body 2 toward the side away from the terminal block 1 to form the biasing end 252. In this case, the cantilever 25 is a bent arm that fits the shape of the device body 2 so as to form the biasing end 252. By providing a bent arm that fits the shape of the device body 2, interference during the process of attaching the device body 2 and the terminal block 1 can be reduced, making the attachment easier.

[0111] The biasing end 252 further has a pressing protrusion 253 on the side facing away from the device body 2, which allows the user to better identify the biasing end 252 and press the pressing protrusion 253 to release the elastic lock between the first locking portion 251 and the first engagement portion 15.

[0112] 3, the number of cantilevers 25 may be two, and the two cantilevers 25 are symmetrically distributed on both opposing side surfaces of the device body 2. Accordingly, the terminal block 1 has two first engagement portions 15 symmetrically installed at positions corresponding to the first engagement portions 251 of the two cantilevers 25. The pair of first engagement portions 251 and first engagement portions 15 installed symmetrically can improve the stability of the connection between the device body 2 and the terminal block 1.

[0113] In some embodiments, the top surface of the mounting portion 24 may further include a guide groove 242. The inner wall of the terminal block 1 may be provided with a guide protrusion 14 at a position corresponding to the guide groove 242, and the shape of the guide protrusion 14 is adapted to the shape of the guide groove 242. In the process of mounting the mounting portion 24 into the terminal block 1, the guide groove 242 is mounted along the direction of the guide groove 242, and the engagement between the guide protrusion 14 and the guide groove 242 can guide the mounting direction of the mounting portion 24 in the terminal block 1, and improve the convenience of mounting.

[0114] In some other embodiments, the guide groove 242 may further be located on the inner wall of the terminal block 1, and the guide protrusion 14 may further be located on the surface of the mounting portion 24, similarly guiding the mounting direction of the mounting portion 24 within the terminal block 1.

[0115] The structure of the network access device 100 will be further described below by taking as an example a case in which the guide groove 242 is located on the mounting portion 24 and the guide protrusion 14 is located on the terminal block 1.

[0116] 3 shows a structure in which the guide grooves 242 are located on the top and bottom surfaces of the mounting portion 24, but this is not intended to limit the structure of the device itself. In some embodiments, the guide grooves 242 may also be located on the side walls of the mounting portion 24.

[0117] The structure of the network access device 100 will be further described below, taking as an example a case in which the guide grooves 242 are located on the top and bottom surfaces of the mounting portion 24.

[0118] The number of guide grooves 242 may be one, two or more (two or more), and when the number of guide grooves 242 is two or more, the guide grooves 242 may be uniformly distributed on the top surface and the bottom surface of the mounting portion 24. In the embodiment of the present application, the number of guide grooves 242 is not particularly limited.

[0119] The terminal block 1 is removably connected to the terminal box 200 to facilitate replacement of the terminal block 1. The terminal block 1 can be removably connected to the terminal box 200 by a lock, a fastener, or other methods. The present application is not particularly limited to the removably connected between the terminal block 1 and the terminal box 200.

[0120] The detachable connection between the terminal block 1 and the terminal box 200 will be further described below by taking locking as an example.

[0121] 3 and 4, there may be a second locking portion 16 on the terminal block 1, which is configured to lock into a second engagement portion (not shown) on the inner wall of the terminal box 200 to realize a removable connection between the terminal block 1 and the terminal box 200. In some embodiments, the second locking portion 16 is a protrusion on the terminal block 1, and the second engagement portion may be a locking groove that fits the shape of the protrusion. When the second locking portion 16 is installed in the second engagement portion, the locking between the terminal block 1 and the terminal box 200 is realized.

[0122] In some embodiments, the second locking portion 16 is an elastically deformable protrusion. In the process of attaching and detaching the terminal block 1, the second locking portion 16 can be elastically deformed under the action of an external force, thereby realizing quick attachment and detachment of the terminal block 1.

[0123] In order to verify the improvement of the heat dissipation performance and the overall performance of the network access device 100, the embodiment of the present application further provides a comparative example, where the comparative example adopts the above-mentioned conventional embedded wireless AP device. Below, the heat dissipation performance and the overall performance of the network access device 100 of the present application are tested in conjunction with the comparative example.

[0124] First, under the test condition of 40°C@1800m (area 1800m above sea level, ambient temperature 40°C), a simulation test was conducted on the heat dissipation performance of main chips (e.g. CPU, PHY, DDR, FLASH) and some electronic elements (e.g. CD) in the embedded wireless AP device and network access device 100 of the comparative example, and the results are shown in Table 1. It should be noted that the ambient temperature represented by 40°C here is different from Ta mentioned above, and may be understood as the ambient temperature in which the embedded wireless AP device and network access device 100 of the comparative example exist.

[0125] [Table 1]

[0126] For illustrative purposes, CPU-OSC represents the OSC pin of the CPU, which may be considered as an input and output pin of the CPU, and similarly, PHY-OSC represents the OSC pin of the PHY, which may be considered as an input and output pin of the PHY.

[0127] As can be seen from Table 1, the Tj, Tc and Ta of the main chips (for example) and electronic elements in the network access device 100 of the present application are all smaller than those of the conventional embedded wireless AP device in the comparative example, which shows that the heat dissipation performance of the network access device 100 of the present application is greatly improved compared to the conventional embedded wireless AP device.

[0128] Next, an Internet speed test software is used to perform Internet speed tests on the embedded wireless AP device and the network access device 100 of the comparative example at 2.4G network speed and 5G network speed, respectively, to characterize the performance of the entire device, and the test results are shown in Table 2. The test method of the Internet speed test is a well-known technique for those skilled in the art, and the description is omitted here.

[0129] [Table 2]

[0130] It should be noted that the layout of chips and electronic elements adopted by the conventional embedded wireless AP device in the comparative example is the same as that of the network access device 100 of the present application. Here, the 2.4G Internet speed may be understood as the Internet speed test at the speed of the 2.4G net, and the 5G Internet speed may be understood as the Internet speed test at the speed of the 5G net.

[0131] As can be seen from Table 2, when the configuration is the same, the network access device 100 of the present application has a higher internet speed than the conventional embedded wireless AP device adopted in the comparative example, whether it is 2.4G Internet speed or 5G Internet speed. Therefore, the network access device 100 of the present application has a significantly improved overall device performance compared to the conventional embedded wireless AP device.

[0132] Based on the above, the embodiments of the present application further provide a network access device. The structure of the network access device is further described below in conjunction with the drawings and embodiments.

[0133] Here, Fig. 7 shows an internal schematic diagram of a network access device, and Fig. 8 shows a structural schematic diagram of the network access device. Here, the position shown in the network access device in Fig. 7 may refer to the AA direction in Fig. 1.

[0134] 7 and 8, the network access equipment includes a terminal box 200 and a network access device 100, and the terminal box 200 is configured to be mounted inside a wall. The terminal box 200 is directly embedded in the wall in advance during house construction or interior construction, and a power cable and a communication cable are located inside the terminal box 200. The side of the terminal box 200 exposed on the wall is installed open.

[0135] The terminal block 1 of the network access device 100 is configured to be mounted in the terminal box 200 and electrically connected to the power cable in the terminal box 200, so as to provide high AC current for the network access device 100 through the power cable in the terminal box 200, thereby realizing the power supply of the network access device 100; the communication cable in the terminal box 200 can provide a network input signal for the network access device 100, thereby realizing the function of the network access device 100, and can provide a network signal to mobile phones, tablet computers, smart wearable devices, computers, etc.

[0136] It should be mentioned that since the network access equipment includes the network access device 100, the network access equipment has good heat dissipation performance and excellent overall equipment performance as well.

[0137] The terminal block 1 of the network access device 100 is detachably connected to the terminal box 200 to facilitate replacement of the terminal block 1. For the detachable connection between the terminal block 1 and the terminal box 200, reference may be made to the relevant description above, and the description will be omitted here.

[0138] 7 and 8, in some embodiments, when there are multiple terminal cavities on the terminal box 200, the terminal block 1 may be located in one of the terminal cavities (not shown) having a power cable and a communication cable, and may be removably connected to the inner wall of the terminal box 200 to realize the installation of the terminal block 1 in the terminal box 200. In this case, the network access equipment may further include a switch panel 300, which may be installed in a position corresponding to the other terminal cavities of the terminal box 200, thereby meeting the power consumption needs of the user.

[0139] In some embodiments, the switch panel 300 may cover all the terminal cavities of the terminal box 200, and may further be provided with an opening (not shown) at a position corresponding to the terminal block 1, which is adapted to the shape of the terminal block 1, so that the terminal block 1 can be assembled into the corresponding terminal cavity through the opening, and the network access device 100 can be integrated onto the switch panel 300, so that the network access device 100 has the advantages of being beautifully installed and not taking up space.

[0140] Referring to Fig. 9, Fig. 9 is an exploded view of the device body and the terminal block in the network access device according to the embodiment of the present application. The terminal block 1 further includes a terminal block front case 17, a terminal block bottom case 18, and a first magnet 19, where the first magnet 19 is mounted in the receiving space formed by the terminal block front case 17 and the terminal block bottom case 18. The device body 2 further includes a device body front case 26, a device body bottom case 27, and a second magnet 28, where the second magnet 28 is mounted in the receiving space formed by the device body front case 26 and the device body bottom case 27. When mounted, the polarity of the first surface of the first magnet 19 close to the terminal block front case 17 is a first pole, and the second surface of the first magnet 19 close to the terminal block bottom case 18 is a second pole, and the polarity of the first pole and the second pole are opposite. Accordingly, the polarity of the third surface of the second magnet 28 close to the bottom case 27 of the device body is the second pole, and the polarity of the fourth surface of the second magnet 28 close to the front case 26 of the device body is the first pole. Exemplarily, the first pole is a north pole and the second pole is a south pole, or the first pole is a south pole and the second pole is a north pole. By setting the first surface of the first magnet 19 and the third surface of the second magnet 28 to opposite polarities, the connection stability between the terminal block 1 and the device body 2 can be improved, and they are less likely to fall off during use.

[0141] In some embodiments, in the network access device 100 having the locking structure shown in Fig. 3, a first magnet 19 and a second magnet 28 may be further provided on the terminal block 1 and the device body 2 as shown in Fig. 9. In this embodiment, by adding the first magnet 19 and the second magnet 28, the stability during connection can be further improved.

[0142] In some embodiments, only the first magnet 19 and the second magnet 28 are installed on the network access device 100, but no locking structure is installed. In some application scenarios, especially in power strips, the gap between different sockets is small, so if a locking structure is used, the side may be interfered with by adjacent devices, making it difficult to press and remove.
