Description

Technical Field

[0001] This utility model relates to the field of electrical installation device technology, specifically to a coaxial cable power supply device. Background Technology

[0002] As people's living standards continue to improve, more and more smart home products are entering people's daily lives. Although most smart home products have low power consumption and can be powered by batteries, some smart home appliances still require power cords for continuous operation over long periods. However, most older houses have fixed wiring that was not designed with smart home products in mind, and lack outlets for powering smart home devices. This makes installation difficult, increases costs and time, and sometimes even necessitates changing the preferred installation location or abandoning the installation altogether. Therefore, there is a need to design a device that facilitates power supply for smart home products, reducing the difficulty of installation in older houses and making smart home renovations easier. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a coaxial cable power supply device that can be connected in series with the coaxial cable of satellite digital television, thereby facilitating smart home devices to obtain power from the coaxial cable and reducing the installation difficulty of smart home appliances.

It can then supply power to smart home appliances such as low-power cameras, temperature and humidity sensors, and door and window status sensors located outside the house through the power supply terminals. Since the installation locations of these smart home appliances located outside the house are highly similar to the installation locations of the coaxial cable, the power supply of the satellite system can be shared through the coaxial cable power supply device, thus solving the power supply problem of smart home appliances. This avoids the increase in installation costs and time caused by the lack of reserved power sockets, and simplifies the difficulty of intelligent transformation of old houses.

The input terminal of the first DC voltage regulator circuit is electrically connected to the input connector of the coaxial cable, and the input terminal of the second DC voltage regulator circuit is electrically connected to the output terminal of the first DC voltage regulator circuit.

[0008] The coaxial cable power supply device described above includes a DC-DC power chip of model SY8113B and its peripheral circuits in the second DC voltage regulator circuit.

[0009] In the aforementioned coaxial cable power supply device, an inductor is connected in series between the voltage stabilizing circuit and the coaxial cable input connector.

[0010] In the aforementioned coaxial cable power supply device, both the coaxial cable input connector and the coaxial cable output connector are male F-type connectors.

[0020] 100 Housing, 110 Power terminal, 120 Coaxial cable input connector, 130 Coaxial cable output connector, 140 Heat dissipation holes, 200 Circuit board. Detailed Implementation

[0021] The embodiments of this utility model are described in detail below, with reference to Figure 1 and Figure 2 This utility model provides a coaxial cable power supply device, including a housing 100 and a voltage regulator circuit. The voltage regulator circuit is disposed within the housing 100. The housing 100 is provided with a coaxial cable input connector 120, a coaxial cable output connector 130, and a power supply terminal 110. The coaxial cable input connector 120 and the coaxial cable output connector 130 are directly electrically connected. The input terminal of the voltage regulator circuit is electrically connected to the coaxial cable output connector 130. The voltage regulator circuit is disposed on a circuit board 200 within the housing 100, and the output terminal of the voltage regulator circuit is electrically connected to the power supply terminal 110.

[0022] This coaxial cable power supply device can be connected in series with the coaxial cable in a satellite digital television system, allowing smart home appliances to draw power from the coaxial cable by electrically connecting to the power supply terminal 110 on the device. Since the installation locations of smart home appliances located outside the house often overlap significantly with the layout of the coaxial cable between the set-top box and the satellite antenna, connecting several of these coaxial cable power supply devices in series with the coaxial cable can avoid increased installation costs and timelines, or even abandonment of installation, due to the lack of pre-installed sockets. This coaxial cable power supply device facilitates the installation of smart home appliances such as cameras or sensors located outside the house, solving the power supply difficulties for smart home appliances during the intelligent renovation of older houses, and reducing the time and cost of intelligent renovation of older houses.

[0023] In practice, smart home appliances located outside the house typically have low power consumption and are powered by 5V or 12V DC. Satellite antennas generally operate on a voltage range of 13V to 18V. Therefore, the voltage regulator circuit usually consists of two DC regulator circuits. The input of the first DC regulator circuit is electrically connected to the coaxial cable input connector 120, converting the DC power from the coaxial cable into a stable 12V DC power. The input of the second DC regulator circuit is electrically connected to the output of the first DC regulator circuit, converting the 12V DC power output from the second DC regulator circuit into a stable 5V DC power. The outputs of both the first and second DC regulator circuits are electrically connected to the power terminal 110, allowing 5V or 12V DC power to be supplied to the connected smart home appliances through the power terminal 110. (Refer to...) Figure 4 and Figure 5In this embodiment, the first DC voltage regulator circuit consists of a DC-DC power chip UP1 (model MP2331) and its peripheral circuitry, and the second DC voltage regulator circuit consists of a DC-DC power chip UP2 (model SY8113B) and its peripheral circuitry. Pin 2 of the DC-DC power chip UP1 is electrically connected to the coaxial cable input connector 120. Pin 5 of the DC-DC power chip UP1 is electrically connected to pin 5 of the DC-DC power chip UP2 and the corresponding 12V power supply terminal 110. Pin 6 of the DC-DC power chip UP2 is electrically connected to the corresponding 5V power supply terminal 110 via inductor LP2. (Refer to...) Figure 4 In this embodiment, an inductor L1 is connected in series between pin 2 of the DC-DC power chip UP1 and the coaxial cable input connector 120. The inductor L1 is used to suppress electromagnetic interference and current surges. Capacitors CP12, CP5, and CP6 are also connected in parallel to ground at pin 2 of the DC power chip UP1. These capacitors, together with the inductor L1, form a low-pass filter, blocking high-frequency signals from passing through. This prevents high-frequency signals on the coaxial cable from being transmitted to smart home devices through the voltage regulator circuit, ensuring that the voltage regulator circuit can only obtain low-frequency DC power from the coaxial cable.

[0024] Understandably, the coaxial cable input connector 120 and coaxial cable output connector 130 can be selected as metric or imperial F-type connectors depending on the specifications of the coaxial cable used by the satellite digital television system in the application area. (Refer to...) Figures 1 to 3 In this embodiment, the outer casing 100 is composed of two upper and lower half-shells joined together. To facilitate wiring and installation, a coaxial cable input connector 120 and a coaxial cable output connector 130 are respectively located at both ends of the outer casing 100. Power terminals 110 are located on the side of the outer casing 100. Both the coaxial cable input connector 120 and the coaxial cable output connector 130 are female F-type connectors, i.e., F-type connectors with external threads and internal holes. Heat dissipation holes 140 are provided on both sides of the outer casing 100 for heat dissipation of the voltage regulator circuit.
