Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only preferred embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

Accordingly, referring to fig. 1 to 5, the packaging apparatus of the network signal transformer of the present embodiment includes:

the rubber shell 10 is provided with a shell groove 12 in the middle, and the side wall of the rubber shell is provided with a plurality of U-shaped grooves 11 corresponding to and replacing the positions of the existing pins; the front side wall and the rear side wall of the present embodiment are symmetrically provided with 8U-shaped grooves 11, respectively.

A coil (not shown) which is arranged in the shell groove of the rubber shell and is reserved with a plurality of leads; and each lead of the coil is implanted into the U-shaped groove on the side wall at the corresponding position of the rubber shell. In the embodiment, the lead wires correspond to 16 lead wires, and the front 8 lead wires correspond to 8U-shaped groove positions on the front side wall; the back 8 lead wires correspond to 8U-shaped groove positions of the back side wall, and each lead wire is correspondingly implanted into the U-shaped groove respectively. A coil (coil) is a continuously wound insulated wire that is a layer of non-conductive material wrapped uniformly and hermetically around the wire. A plurality of thread packages are arranged in the shell groove of the rubber shell.

The bottom surface of the PCB 20 is upwards embedded into the rubber casing for fixing, lead wires and the bonding pads 21 on the PCB 20 are provided with lead-free solder paste, and then reflow soldering is carried out to ensure that the lead wires and the bonding pads 21 on the PCB are fixedly conducted.
