Description

Technical Field

[0001] The present invention relates to the technical field of network interfaces, and in particular to a multi-port network connector. Background Art

[0002] In network connection technology, people need network connectors as a transmission bridge to realize data transmission. The most common is the RJ45 type network port commonly used in the market, which is widely used in our daily life. When it is necessary to connect external electronic devices, a connector with a network interface will be used. In some office places or emergency situations, it greatly improves people's needs and brings convenience to life and work. Nowadays, with the trend of electronic products developing towards small size and thinness, as well as in conference rooms with a large number of people or places such as broadband switches, hubs, servers and communication applications, traditional network connectors with large size and few ports can no longer meet the needs of users.

[0003] However, as the number of ports increases, the number of plugged signal lines also increases. At this time, not only will the connector be pulled from multiple directions, but the space at the port will also become larger, making it easy for dust to enter. After a long time, it will cause poor contact at the connector interface. Therefore, we propose a new type of network connector for multi-port connection to solve the problem of loose ports caused by pulling in multiple directions. Summary of the invention
