Problems solved by technology
However, the traditional existing equipment used in receiving and sending, all kinds of power supply circuits have the following disadvantages: the coil is wound on the graphite rod, and then the end pin of the coil is directly welded on the circuit board, or the Coils are wound on magnetic rods and magnetic beads, and then the end legs of the coils are directly welded on the circuit board. Equipment using this circuit method has large losses, consumes power, occupies space for components, is troublesome to process, and costs a lot. high

The invention discloses a three-in-one network next-generation internet of things power supply device. On the basis of an existing three-in-one network next-generation internet of things branch distributor, a coil inductor, winding a graphite rod and a magnetic rod, on a circuit and a coil inductor, winding a magnetic bead, of the circuit in the prior art are replaced by chip inductors, wherein a coil end pin of the coil inductor winding the graphite rod and the magnetic rod is directly welded to a circuit board, and a coil end pin of the coil inductor winding the magnetic bead is directly welded to the circuit board. The power supply device has the advantages of saving energy, being small in size and the like, and also overcomes the defect that in the prior art, an inductance element emits heat due to the fact that the coil of the inductance element winds the graphite rod and the coil end pin is directly welded to the circuit board, or the coil of the inductance element winds the magnetic rod and the magnetic bead, and the coil end pin is directly welded to the circuit board.
Description
technical field [0001] The invention relates to the three-networks-in-one Internet of Things, specifically the power supply for the signal reception and transmission of the Internet of Things, and more specifically the triple-networks-in-one next-generation Internet of Things power supply suitable for two-way interactive signal transmission of audio and video "three-networks-in-one" power supply. Background technique: [0002] At present, the triple play project is rapidly developing in full swing, and the next-generation Internet of Things business is gradually being realized, which makes the connection of the entire network wider and wider, and the signals are transmitted in a two-way interactive manner. Sending quality technical requirements are getting higher and higher. However, the traditional existing equipment used in receiving and sending, all kinds of power supply circuits have the following disadvantages: the coil is wound on the graphite rod, and then the end pi...
