The heart of an RJ45 module is a modular jack. Gold-plated wires or socket holes maintain a stable and reliable electrical connection to the modular socket clips. The electrical contact is further enhanced as the plug is inserted due to the friction between the spring and the jack.
The jack body is designed with an integral locking mechanism so that when the modular plug is inserted, maximum pull strength is created outside the interface of the plug and jack. The wiring module on the RJ45 module connects the twisted pair through the "U"-shaped wiring slot, and the locking shrapnel can fix the RJ45 module on the information outlet device such as the panel.
