Problems solved by technology

[0003] However, due to the application of RJ type connectors, it is easy to be affected by external noise interference and affect the quality of network signal transmission. The reasons for noise interference can be roughly divided into two major parts, one is from the RJ type The electromagnetic wave interference around the connector, the second is the internal interference of the RJ type connector, which makes the RJ type connector easy to generate high-frequency waves that can interfere with other electrical equipment, and the signal of the RJ type connector itself is also easily transmitted by the external transmission line. Affected by the noise generated, therefore, there is a research and development design based on the metal shielding shell on the outer edge of the RJ-type connector and the filter module installed in the connector to solve the above shortcomings, so that the RJ-type connector can be used The received external network signal is filtered to filter out unnecessary noise and retain the actual useful signal. A filter module is installed inside the RJ type connector, and it is connected with the original multiple signal terminals and multiple transmission terminals, etc. , during the remanufacturing process, it is necessary to repeatedly enter the reflow furnace for surface-mount welding processing operations, and each high-temperature surface-mount welding processing operation is likely to be affected by the high temperature of subsequent welding operations, resulting in the completion of the previous welding. The dissolution of the solder at the position leads to the loss of the solder at the first soldering position due to high temperature dissolution, which instead causes the phenomenon of inaccurate soldering at the first soldering position, or the terminal loosens and falls off due to the loss of solder, which will cause RJ The defect of the type connector, becoming a defective product, also increases the product failure rate and increases the manufacturing cost

[0004] Therefore, how to solve the problem and trouble that the current RJ-type electrical connector must go through multiple surface-mounting welding operations, which causes inaccurate welding at the first welding position, and because the RJ-type connector is equipped with filter modules, light-emitting diodes and multiple terminals, etc. , resulting in an increase in the number of welding operations, resulting in the lack of high temperature that can easily affect the quality of various electronic components, which is the direction that relevant manufacturers in this industry want to study and improve.
