You’re probably talking about connecting a network cable (Ethernet cable) to an internet connection (such as a network socket or router port) and how a screwdriver might be used, especially when installing a keystone module or network socket, where the individual cable wires need to be connected.

It’s important to understand that a standard screwdriver is NOT intended for directly connecting an Ethernet cable to a router or network socket. Special tools are used for this task.

Direct connection (plug to socket): To simply connect a pre-wired Ethernet cable (with RJ45 connectors) to a router or network socket, you don’t need a screwdriver. You simply insert the plug into the appropriate socket until it clicks into place.

Where a screwdriver could come into play (but shouldn’t, without the right tool):

A screwdriver could be used when installing a network socket or keystone module, where the 8 individual wires of a network cable are connected to special terminals. These terminals are designed to cut through the insulation of the wires and create an electrical connection.

However, there are special insertion tools for this task (also called LSA insertion tools or Krone tools). A regular screwdriver is unsuitable for this task and can even cause damage:

Damage to the terminals: The sharp edges of a screwdriver can bend or break the delicate contacts in the terminal.
Damage to the wires: The screwdriver cannot cleanly cut through the insulation or damage the wires themselves.
Insecure connection: A poorly established connection leads to network problems (slow speed, packet loss, dropped connections).
Risk of injury: Slipping with the screwdriver can cause injury.
If you really need to connect the individual wires of a cable in a network socket or keystone module, follow these steps (but please use the correct tools):

Tools you actually need:

LSA insertion tool (Krone tool): This is the essential tool for this task. It presses the wire securely into the terminal and simultaneously cuts off the excess wire.
Wire strippers: For removing the outer cable insulation.
Side cutters: If the LSA tool does not have a cutting function.
Instructions for connecting the wires (using the correct tools):

Cable preparation:
Measure the required length of cable.
Carefully strip approximately 3-5 cm of the outer insulation of the network cable with wire strippers, taking care not to damage the inner wire pairs.
Untangle the four twisted pairs of wires and arrange them according to the color code indicated on the network outlet or keystone module (usually T568A or T568B). The codes are usually color-coded.
Installing the wires:


Place each individual wire into the corresponding notch of the terminal on the network outlet or keystone module. Ensure the color sequence is correct.
Take your LSA insertion tool. Place it on the wire in the notch and press down firmly. The tool will push the wire into the terminal and cut through the insulation, establishing contact. At the same time, the tool will trim off any excess wire.
Repeat this for all 8 wires.
Verification:


Visually check that all wires are securely connected and that the correct color sequence has been observed.
For professional installation, a cable tester should be used to verify continuity and correct wiring.
In summary: “Connecting” an internet connection with a screwdriver is not a recommended or safe method when installing Ethernet cables in network outlets or keystone modules. Special LSA insertion tools are essential to ensure a reliable and permanent connection. If you’re installing a pre-wired connector, you don’t need any tools at all
