Description

Integrated module of miniaturized Ethernet network transformer

Technical Field

The utility model relates to a miniaturized ethernet network transformer's collection moulding piece belongs to ethernet network transformer technical field.

Background

Electronic components are now widespread in various electronic devices, are the most basic parts of electronic devices, and have a decisive influence on the electronic devices and information systems. The rapid development of electronic information technology has brought higher requirements for the number of instructions executed by equipment per second, power consumption, heating condition, shape and size and the like in recent years, so that the demand for miniaturization of electronic components is more and more strong, the miniaturization and high integration development of electronic components has become a necessary trend, and in order to meet the miniaturization requirement of a system, an Ethernet transformer is integrated through the cross fusion of the process maturity of a chip, a transformer, a capacitor and a resistor, a component fault mode, welding reliability and risk assessment and packaging technology.

The traditional structural design is that an enameled wire is wound on a large magnetic ring and a small magnetic ring to form a combined magnetic ring coil, the combined magnetic ring coil is fixed in a plastic base, the free end of the enameled wire is electrically connected to a metal terminal, and the metal terminal is fixedly connected to two sides of the bottom of the plastic base. The transformer inside adopts special waterproof casting glue to fix and protect for reach the plastic envelope purpose, the condenser passes through reflow soldering in advance and welds on the PCB board, and on another end metal terminal table pasted the transformer to the PCB board, the PCB board linked through welding and product base, constitutes complete ethernet transformer. When the transformer is welded, the inductor is easy to desolder to cause product failure due to the need of reflow soldering. Meanwhile, the overall height of the product is too high, and the miniaturization requirement cannot be realized.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: an integrated module of a miniaturized ethernet network transformer is provided to solve the above-mentioned problems in the prior art.

The utility model discloses the technical scheme who takes does: the utility model provides an integrated module of miniaturized ethernet network transformer, includes magnetic ring solenoid, PCB board and condenser, and the magnetic ring solenoid adopts a plurality ofly, and fixed connection is in PCB board both sides respectively, and the condenser welding is on the PCB board, is provided with the contact pin of connecting magnetic ring solenoid line tail on the PCB board, and PCB board fixed connection just the contact pin passes the base bottom on the base.

Preferably, the base is of a U-shaped structure, and the inner cavity of the base is in full plastic package.

Preferably, the tops of the two sides of the base are respectively provided with an inverted L-shaped clamping tongue, and the inverted L-shaped clamping tongues are clamped with the PCB.

The utility model has the advantages that: compared with the prior art, the utility model discloses constitute complete ethernet transformer. When the solenoid is welded, reflow soldering is not needed, so that the problem that the inductor is easy to desolder to cause product failure is solved. Meanwhile, the product height is reduced, and the miniaturization requirement is realized.
