WHAT ARE THE STEPS IN CRIMPING RJ-45 CONNECTOR?

RJ-45 Connector

The "RJ" in RJ45 stands for "registered jack," since it is a standardized networking interface. The "45" simply refers to the number of the interface standard. This is an eight wire connector commonly used to connect devices into a local area network (LAN).

RJ45 is a type of connector commonly used for Ethernet networking including connection with PC network cards, data switches, Wi-Fi access points, and routers. It is connected to each end of Ethernet cables and acts as the main source for transferring data. It looks similar to a telephone jack, but is slightly wider. Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are sometimes also called RJ45 cables.

Crimping Tool

A crimping tool is a device used to conjoin two pieces of metal by deforming one or both of them to hold each other. The result of the tool's work is called a crimp. 

Two Types of Ethernet Cable:

Straight-Through Cable

Straight through cable is a type of  twisted pair cable that is used in a local area networks to connect different type of computer devices to a network hub such as router. Straight through refers to cables that have the pin assignments on each end of the cable. In other words, Pin 1 connector A goes to Pin 1 on connector B, Pin 2 to Pin 2. etc. Straight through wired cables are most commonly used to connect a host to a client.

Crossover Cable

Crossover cable is a commonly used in most computer bet working transmission. Crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type, e.g. two computers or two same type, e.g. two computers or two switches to each other such as router to router. The internal wiring of crossover cables reverses the transmission and receive signals.

Crimping RJ-45 Connector Using Scissor:

-------------------------------------------------------------

Step 1: Cut 1 inch (25mm) into the outer sheath.

Gently cut into the plastic sheath, cut it about 1 inch (25 mm) from the end of the cable. When the scissors penetrate the sheath rotate the cable and scissors to create a cut around the cable. Don't cut too deep, make sure you don't cut into the wires inside. Then, stick your fingertips under the sheath and pull it off towards the end.

-------------------------------------------------------------

Step 2: Separate and straighten out the wires.

Use your fingers to untwist and straighten the exposed wires after you remove the sheath. If there is a plastic core or wire separator cut it away with your scissors.

------------------------------------------------------

Step 3: Put the wires in the right order.

Arrange the wires from left to right, the color order is up to you, its either the color codes of the straight-through or crossover cable that you will use. They need to be fixed in a specific order to be properly crimped into the RJ-45 connector.

------------------------------------------------------

Step 4: Trim the wires 1/2 inch (13 mm).

Combine the wires and hold it with your thumb and forefinger. Then, use your scissors to cut them. Make sure they are cut evenly. The wires need to be even to fit the grooves in the connector If you cut the uneven wires move further down and cut it again so that their ends are in a straight line.

------------------------------------------------------

Step 5: Fit the wires into the grooves.

Hold the connector so that the metal pins or brackets are facing up and the clip is facing down. Hold the small wires together in the correct order and slide them into the connector. They should fit into the connector grooves, with the end of the cable sheath fitting just beyond the base of the connector.

------------------------------------------------------

Step 6: Press the pins down.

Locate the small metal pins at the ends of the connector grooves. Use a thin, flathead screwdriver to push each of the pins down. Push the pins 1 by 1 to press them all the way into each wire. Be careful not to crack or break the plastic connector.

------------------------------------------------------

Step 7: Tug on the end to make sure it's secure. 

Double check that all the pins are pressed into the wires, and pull lightly on the connector to make sure it won't slide. Each of the pins must be inserted at the same level to form an even line. Lightly shake the cable and listen for any rattling that may indicate that one of the pins is not secure.
