Abstract

The invention relates to a network transformer shell, a network transformer and a manufacturing method thereof, and belongs to the technical field of network transformers. The network transformer shell comprises a shell body made of thermosetting flame-resistant materials. The shell body is in a box cover shape and comprises a shell side wall, a PIN installation blind hole is formed in the end face of an opening of the shell side wall, the network transformer shell further comprises a conductive PIN, one end of the PIN is inserted into the PIN installation hole, and the PIN and the PIN installation hole are in interference fit. By inserting one end of the PIN into the PIN installation hole, the whole network transformer shell manufacturing process can be completed just through injection and plugging steps, the follow-up magnetic core embedding post-welding procedure can be automatically executed, the number of production procedures is decreased, the production flow is simplified, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of network transformers, in particular to a network transformer casing, a network transformer and a manufacturing method thereof. Background technique [0002] Existing network transformer enclosures such as figure 1 As shown in , it includes shell 1 and PIN pin 2, wherein, PIN pin 2 is shown as two rows in the finished network transformer, and PIN pin 2 is embedded in shell 1 by injection molding, and the manufacturing process is as follows: PIN pins that are punched into right angles 2→Put the PIN pin 2 and the raw materials of the shell 1 together in the injection mold to complete the injection molding→Remove the injection nozzle→Sand blast and deburr→Bend the PIN pin 2 again, cut off more PINs→Electroplating→Break the inner PIN→Complete the production of the shell. The whole production process is relatively complicated, with many processes and low efficiency. Contents of the invention [0003] The in...
