Description

Integrated network transformer

The invention relates to the technical field of network transformers, and in particular to an integrated network transformer.

The network transformer includes a plastic shell and a coil. In the past, the pins were first injection molded on the plastic shell, and then the coil was installed in the plastic shell. Finally, the wires of the coil were wound around the pins. Such products have a complicated manufacturing process, high processing costs, and subsequent assembly is more troublesome.

The invention aims to solve at least one of the technical problems existing in the prior art. To this end, the invention proposes an integrated network transformer, in which the coil assembly and the pins are injection-molded together with a sealing block, thereby eliminating the trouble of subsequent assembly of the network transformer.

According to the first aspect of the present invention, an integrated network transformer includes: a coil group, including a first coil and a second coil, the first coil and the second coil are arranged opposite to each other in the front-to-back direction; a plurality of pins are provided, and the plurality of pins are distributed in pairs on both sides of the coil group, the pins include a packaging part and a contact part, the leads of the first coil and the leads of the second coil are respectively connected to the corresponding packaging parts; a packaging block, used to package the coil group and the packaging part of the pins, and the contact part protrudes from the packaging block.

Such a network transformer is more convenient to connect the first coil and the second coil in the early stage, because only the first coil and the second coil need to be connected to the pins, and the sealing block is formed by glue injection in the later stage to encapsulate the first coil and the second coil. The sealing block can also increase the connection strength between the coil group and the corresponding pins.

According to some embodiments of the present invention, the packaging portion and the contact portion are integrally formed, and the width of the packaging portion is greater than the width of the contact portion, so that the packaging portion can be better packaged, thereby improving the strength of the pin after packaging.

According to some embodiments of the present invention, a rounded corner structure is provided at the connection between the packaging part and the contact part, and the rounded corner structure is used to enhance the connection between the packaging part and the contact part.

According to some embodiments of the present invention, the front end and the rear end of the sealing block are both provided with reinforcement blocks, and the contact portion protrudes out of the reinforcement blocks.

The provided encapsulation block 300 completely encapsulates the first coil 110, the second coil 120 and the lead 200, eliminating the trouble of winding the coil lead on the plastic shell. After the provided lead 200 is connected to the first coil 110 and the second coil 120, the entire network transformer is directly encapsulated by injecting glue, and the encapsulation block 300 is formed after the injection glue is cured. It is more convenient for the press to connect the first coil 110 and the second coil 120 in the early stage, because only the first coil 110 and the second coil 120 need to be connected to the pin 200, and the first coil 110 and the second coil 120 are encapsulated by the encapsulation block 300 in the later stage. The encapsulation block 300 can also increase the connection strength between the coil assembly 100 and the corresponding pin 200. It can be understood that the pin 200 is centrally connected to the corresponding template, and in order to avoid the end of the pin 200 being unable to be immersed in solder during the immersion soldering process, the package part 210 is connected to the corresponding template through an auxiliary sheet.

In some embodiments, there are several coil assemblies 100, and the several coil assemblies 100 are distributed along the left and right directions. It can be understood that the several coil assemblies 100 enable the network transformer to have multiple transformer assemblies, which is convenient for realizing more complex circuits.

In some embodiments, the leads of the first coil 110 and the leads of the second coil 120 are respectively welded to the corresponding packaging part 210, and the welding is convenient and fast. It is understandable that before the encapsulation, welding the leads of the first coil 110 and the leads of the second coil 120 is more convenient and fast, and is conducive to mechanized batch welding, making the manufacturing process of the entire network transformer simpler and eliminating the trouble of manually winding the leads in the past.

In some embodiments, the packaging portion 210 and the contact portion 220 are integrally formed, and the width of the packaging portion 210 is greater than the width of the contact portion 220, so that the packaging portion 210 can be better packaged, thereby improving the strength of the packaged lead 200.

In some embodiments, a rounded corner structure 230 is provided at the connection between the packaging portion 210 and the contact portion 220, and the rounded corner structure 230 is used to enhance the connection between the packaging portion 210 and the contact portion 220.

In some embodiments, the front and rear ends of the sealing block 300 are provided with reinforcement blocks 310, and the contact portion 220 protrudes from the reinforcement blocks 310. It can be understood that the reinforcement blocks 310, i.e., thickening blocks provided at the front and rear ends of the sealing block 300, are used to thicken the thickness of the front and rear ends of the sealing block 300, thereby making the pin 200 more stably connected in the sealing block 300, and cooperating with the structure of the pin 200 to achieve a stable connection of the pin 200.

In some embodiments, the contact portion 220 is provided with a bending step 221, which is used to bend the contact portion 220.
