How to connect a coaxial cable connector？

How to connect a coaxial cable connector. A coaxial cable is a cable covered with an insulating (non-conductive) material shell.

Method 1

1. Select the cable model. The term cable can be a bit confusing. Check the shell of the cable, which generally has instructions about the cable luck. In the family, the most commonly used sizes are RG-6 and rg-59.

RG stands for "radio guide". The number represents the diameter and inner diameter of the wire (59 means 0.059 and 6 means 0.06). This also includes the thickness of the shell and cable, which represents how much signal is lost per unit length.

You will also see the word RF on the cable, which stands for "radio frequency".

Although the finer and lower standard rg-59 is still used in some old houses, most non industrial coaxial cable connectors are best known as RG-6. Commercial installers will use thinner RG cables, such as rg-11 (it is only applicable when the signal source is more than 200 feet away from your terminal).

The RG cable for general purpose for household use shall be 75Ohm (RG-6 or rg-59).

Note that all cables and coaxial cable connectors have different quality, and choose the best quality.

2 select the correct connector. Most home video installation connectors are made of F-type connectors. However, your system may also use n-type connectors.

Note that there are several F-type RG-6 cables available, and the crimped connector is preferred.

The screw connector is easy to use, but it is less safe, and will leave some small air ports. Some people think this will affect the signal quality.

A crimped connector has two parts: a ring (or crimper) and a terminal. They are difficult to install, but as long as they are used correctly, they can get the longest length and the best connection.

Understand that to make a connection, you need the same type of female and male connectors.

The male connector has a center wire, while the female connector has no center wire. Make sure you use the opposite pole. Most cables have male connectors at one end.

For very small cables, use SMA (mini version a) connectors.

Method 2

Peel off the cable

The first step in connecting the connector is to prepare the termination of the coaxial cable.

1. Cut the outer skin of the cable.

2. Peel off 1 / 2 of the skin (usually black).

Be careful not to cut the metal strip inside the appearance. The metal strip may be some "loose" conductor and sheet metal wrapped around the conductor.

3. Carefully pull the inner metal belt (second channel) out of the outer skin. Check to make sure that the metal belt wires are leaking out and the copper wires can be touched.

4. Peel off the insulating plastic (usually white, but may also be transparent) from the inner core cable.

Never scratch or scratch the middle wire. Any wire damage can cause serious signal problems.

5. Push the connector into one end of the cable so that the copper wire in the middle can be pulled out.

Ensure that the insulation (aluminum foil) is stripped off so that the connector terminals can be accessed.

6. Screw the connector to one end of the cable. The threads are embedded in the housing and closely fit together.

Method 3

Use crimped connectors

This is another way to connect coaxial cable connectors.

1. Put the curved ring on one end of the cable.

2. Peel 1 / 4 of the skin.

3. Peel off the shell, conductor skin and insulation layer to expose the internal conductor.

4. Leave 1 / 8 of the insulation.

5. Place the terminal on one end of the conductor so that the copper core can be pulled out of the hole.

6. Push the crimp connector into one end of the cable so that the connector can enter between the paddle box and the outside of the house.

This may be difficult to do. Try holding one end of the cable with pliers or a pair of clips. Don't bend when pushing in.

7. Draw the ring into the outside of the cable.

8. Peel off any loose wires.

9. Cut off the outer skin of the connector end of the inner center wire.

10. Drag the connector to make sure it is connected.

Tips

If you have a high-speed network and exceed the speed of two TVs, make sure you use a high-quality RG-6 connector. When pushing the connector into the cable conductor, it is necessary to make some preparations to get a clear image and a good connection. Use push on connectors available in any popular home repair center. When preparing one end of the wire, make sure not to bend the copper core connector, otherwise it will lead to some network problems, such as intermittent connection and data loss.

You can buy cutters, crimpers and pliers for certain coaxial cables of specific diameter. These tools need practice to know how to use. You don't need special tools to make connectors. As long as you are careful, ordinary pliers can also be used.

Do not use f-nut connectors. If this type of cheap undetected connector is used, the cable signal will "leak out". This can cause the signal to leak from the wire and cause distortion, vertical lines, laterally moving short lines, or random small white spots on the screen.
