[0035] In existing technologies, traditional GPON equipment mainly focuses on data transmission. For cable TV access to CATV signals, additional set-top box equipment is required, resulting in more lines and more complex wiring.

[0036] This utility model proposes a GPON-based device.

[0037] Please see Figures 1 to 4As shown, in one embodiment of this utility model, the GPON-based device includes: a housing 100, a main control board 200, a CATV connector 210, and a network connector 220. The housing 100 has a cavity, and the outer bottom of the housing 100 protrudes towards the cavity, forming a receiving groove 130 on the outer wall of the housing 100. The receiving groove 130 has an opening 131 that communicates with the cavity. The main control board 200 is disposed within the cavity and fixedly connected to the housing 100. The main control board 200 is electrically connected to a first optical fiber cable, which connects to an external optical fiber at the opening 131. The receiving groove 130 is used to receive the external optical fiber. The CATV connector 210 is electrically connected to the main control board 200 and is used to connect a television. The network connector 220 is electrically connected to the main control board 200 and is used to connect a local area network (LAN) cable.

[0038] In practical implementation, a cavity is formed inside the housing 100 to accommodate the main control board 200, preventing damage to the main control board 200. The CATV connector 210 and network connector 220 are mounted on the main control board 200 and electrically connected to it. The CATV connector 210 is used to connect a television, and the network connector 220 is used to connect a network cable for network transmission. Multiple network connectors 220 are provided, allowing connection to multiple electronic devices. It is understood that clearance openings are also provided on the sidewalls of the housing 100 to facilitate the connection of the corresponding cables to the CATV connector 210 and network connector 220. The outer bottom wall of the housing 100 protrudes into the cavity, forming a receiving groove 130 at the bottom of the housing 100. It should be noted that the external optical fiber has a connector, and the external optical fiber and connector are located within the receiving groove 130. An opening 131 is provided on the sidewall of the receiving groove 130 to facilitate the connection of the external optical fiber to the first optical fiber cable. Furthermore, in the specific implementation process, a groove is recessed at the bottom of the housing 100, and the external optical fiber is distributed along the groove. In this way, pulling the external optical fiber will not damage the connection between the external optical fiber connector and the first optical fiber cable, ensuring the stability of optical fiber transmission, and also facilitating the management of the external optical fiber cable. Further, multiple cable clips are arranged along the extension direction of the groove, with the clips spaced apart. The free ends of the cable clips are bent towards the groove to prevent the external optical fiber from leaving the groove on its own.

[0039] This invention employs a design where the outer bottom of the housing 100 protrudes towards the cavity, forming a receiving groove 130 on the outer wall of the housing 100. The receiving groove 130 accommodates a first optical fiber cable. An external optical fiber connects to the first optical fiber cable through the receiving groove 130 and the through-hole 131, electrically connecting the external optical fiber to the main control board 200. The CATV connector 210 is also electrically connected to the main control board 200. Thus, the GPON-based device has CATV functionality, allowing connection to a television set, and also enables network transmission via the network connector 220. No additional routing equipment is required, and the wiring and connections are simple and easy to install.

[0040] In one embodiment, the GPON-based device further includes a connector 300, which is disposed within the cavity. A first optical fiber cable is connected to the connector 300, and one end of the connector 300 is disposed at a port 131, so that an external optical fiber can be plugged into the connector 300 through the port 131.

[0041] In practical implementation, connector 300 is used to connect the first optical fiber cable and the external optical fiber, facilitating the insertion and removal of the external optical fiber and also facilitating equipment installation. The plug of the external optical fiber is plugged into connector 300. The first optical fiber cable can be plugged into connector 300 or directly electrically connected; this is not limited in this embodiment.

[0042] Further, refer to Figure 3 As shown, a limiting component 400 is provided inside the housing 100. The limiting component 400 includes a surrounding plate 410 and a limiting plate 420. The surrounding plate 410 surrounds to form a limiting groove 411. The connector 300 is provided with a limiting ear 310, which is movably disposed in the limiting groove 411 to limit the displacement of the connector 300 in the horizontal plane. One end of the limiting plate 420 is connected to the surrounding plate 410, and the other end extends to the top of the connector 300 and bends in the direction of the connector 300 to form a limiting hook 421 to limit the displacement of the connector 300 in the vertical direction.

[0043] In this embodiment, the limiting component 400 is used to fix the connector 300, preventing the connector 300 from moving and affecting the connection of the external cable. Specifically, the surrounding plate 410 protrudes from the inner wall of the cavity, forming a limiting groove 411. The connector 300 has a limiting ear 310 on its side, which engages with the limiting groove 411, thus limiting the connector 300 and restricting its displacement in the horizontal plane. One end of the limiting plate 420 is connected to the surrounding plate 410, and the other end extends vertically to above the connector 300. The end of the limiting plate 420 is bent toward the connector 300 to form a limiting hook 421. The projection of the limiting hook 421 in the horizontal plane is projected onto the connector 300, thus limiting the vertical displacement of the connector 300.

[0044] In the specific implementation process, the housing 100 is provided with two sets of limiting components 400, and the two sets of limiting components 400 are symmetrically arranged. The connector 300 is located between the two sets of limiting components 400. In addition, the limiting hook 421 is provided with an inclined surface, which connects the top surface and the side surface of the limiting hook 421 respectively. The limiting hook 421 has a certain degree of elasticity. When installing the connector 300, the inclined surface can play a guiding role, which facilitates the installation of the connector 300.

[0045] In one embodiment, the inner wall of the housing 100 is further provided with a limiting groove 411, and the connector 300 is disposed in the limiting groove 411. The limiting groove 411 is formed by the recess in the inner wall of the housing 100. The contour of the limiting groove 411 is adapted to the connector 300. The connector 300 is located in the limiting groove 411, which facilitates the installation of the connector 300.

[0047] Specifically, the first heat sink 500 is bonded to the main control board 200 with thermally conductive silicone to facilitate heat exchange. The main control board 200 exchanges heat with the first heat sink 500, thus dissipating heat and preventing the main control board 200 from overheating. The second heat sink is bonded to the top surface of the main control board 200 for heat dissipation. In this embodiment, several ventilation holes 140 are provided on the top, side walls, and bottom of the housing 100 to facilitate airflow between the cavity and the outside, improving heat dissipation.

[0048] In the specific implementation process, the first heat sink 500 is an aluminum heat sink, and the second heat sink 510 is a nano carbon heat sink. Both are used to dissipate heat from the main control board 200 and improve the heat dissipation effect of the main control board 200.

[0049] In one embodiment, the housing 100 includes an upper housing 110 and a lower housing 120, which are fastened together and surround each other to form a cavity.

The main control board 200 has multiple indicator lights, which emit light to the outside through the light guide pillars 111 and the display ports.

[0050] In practical implementation, both the upper shell 110 and the lower shell 120 are equipped with multiple snap-fit ​​devices. The upper shell 110 and the lower shell 120 are connected by snap-fit ​​devices, facilitating installation and disassembly. The lower shell 120 includes a base plate and a side plate, with the side plate surrounding the base plate. The upper shell 110 is connected to the side plate, and the base plate, side plate, and upper shell 110 together form a cavity. Multiple limiting posts are provided on the side of the upper shell 110 facing the cavity. The limiting posts are in contact with the main control board 200, limiting the displacement of the main control board 200. The lower shell 120 also has a fixing groove, in which foot pads 170 are installed. The foot pads 170 are made of flexible materials such as silicone or rubber to increase friction with the tabletop, providing anti-slip and shock absorption and noise reduction effects.

[0051] One end of the light guide post 111 is connected to the upper shell 110, and the other end extends toward the cavity. When the upper shell 110 is installed on the lower shell 120, the other end of the light guide post 111 is close to the indicator light on the main control board 200, and the light from the indicator light is emitted through the light guide channel.

[0052] Furthermore, in one embodiment, the upper shell 110 is provided with a connecting groove 112, and a decorative film 150 is provided inside the connecting groove 112. The decorative film 150 is light-transmitting. The connecting groove 112 is formed by a recess in the outer wall of the upper shell 110 away from the cavity. The display port is located at the bottom of the connecting groove 112, and the decorative film 150 is adhered inside the connecting groove 112. The indicator light passes through the decorative film 150. In a specific implementation, the decorative film 150 is made of PVC material. In another embodiment, a lampshade is installed at the display port to prevent debris from entering the cavity through the display port and to prevent debris from blocking the indicator light, thus affecting its use.

[0053] In one embodiment, the main control board 200 is also electrically connected to a telephone line connector 230 and an antenna. The telephone line connector 230 connects to a telephone, and the antenna is used to transmit wireless signals. In a specific implementation, an antenna rod 160 is also connected to the side wall of the housing 100. One end of the antenna rod 160 is connected to a connecting seat, which is rotatably connected to the housing 100.
