The male and female RJ45 connectors are two different types of RJ45 interfaces. They have some differences in structure, function, and application scenarios. The following is a detailed introduction:

Structural characteristics

RJ45 male connector: Commonly also known as an RJ45 plug, its shape is similar to a small plastic plug, with 8 metal pins at the front end, which are used to insert into the RJ45 female connector to achieve electrical connection. The casing of the male head is generally made of plastic, which has a certain degree of flexibility and strength to protect the internal metal pins from damage. At the end of the plug, there is usually a device for fixing the network cable, such as a cable clamp or screw, to ensure a firm and reliable connection between the network cable and the plug.

RJ45 female connector: Also known as RJ45 socket or plug hole, it is usually installed on the device panel or network module. There are 8 elastic metal contacts inside the female connector, which are used to closely contact the pins of the RJ45 male connector to achieve data transmission and electrical connection. The casing of the female head is usually designed as an integrated unit with the casing of the device's panel or network module to ensure its stability and durability.

Function and role

RJ45 male connector: Its main function is to transmit the signal of the network cable to the connected device. For instance, when connecting a computer's network card to a network switch or router, a network cable with a male RJ45 connector at one end should be used. Insert the male connector into the female RJ45 connector of the computer's network card to connect the computer to the network, enabling the computer to access network resources.

RJ45 female connector: Its function is to receive the signal sent by the RJ45 male connector and transmit it to the internal circuit of the device for processing. For instance, the front panel of a network switch usually features multiple RJ45 female interfaces, which are used to connect RJ45 male network cables from different devices, enabling network interconnection and data exchange among multiple devices.

Application scenarios

RJ45 male connector: It is often used to make network patch cords, that is, network cables with RJ45 male connectors at both ends, which are used to connect various network devices, such as computers, servers, network printers, etc., to network switches or routers. In addition, in some scenarios where a temporary network setup is required, such as exhibitions and meeting rooms, a large number of network cables with RJ45 male connectors are also used to quickly connect devices and set up a temporary network.

RJ45 female connector: Widely used on the panels of various network devices, such as switches, routers, firewalls, etc., as part of the network interface, it is used to receive connections from the RJ45 male connector. At the same time, RJ45 female connectors are also widely used in network infrastructure such as wall sockets and network patch panels, facilitating users to connect network cables to the building's comprehensive wiring system and achieving network distribution and expansion.
