In the world of video cables, understanding how to create your own connections can save you both time and money. Today, we’re diving deep into the process of making BNC compression connector cables. This guide will cover everything you need to know, including the tools required, types of connectors, and step-by-step instructions. Whether you’re working on a home project or in the security industry, mastering this skill is essential.
Types of Connectors for Video Cables
When it comes to making video cables, there are three main types of connectors you’ll encounter:
- Compression Connectors: These connectors provide a secure and reliable connection, commonly used in professional setups.
- Screw-On Connectors: While easier to use, they are less durable and not weatherproof.
- Crimp-On Connectors: These require precise handling and offer a strong connection, but mistakes can lead to starting over.
For our discussion, we will focus primarily on making cables with BNC compression connectors. However, the principles can apply to other types as well.
Essential Tools for Making BNC Cables
Before you start, make sure you have the following tools on hand:
- Coaxial wire (we will use RG59 for this guide)
- A wire cutter
- A wire stripper
- A compression crimping tool
- F connectors, BNC connectors, or RCA connectors with compression backs
If you’ve purchased a field installation kit, it’s likely that most of these tools are included. Using the right tools is crucial for achieving a successful connection.
Understanding Coaxial Cables
When dealing with analog cameras, you might come across various types of coaxial cables. The most common ones are:
In this guide, we will specifically use RG59. Remember, if you opt for a different type of wire, the gauge size for both the wire and the connector will vary. Using the right size connectors for the correct wire is essential; otherwise, your connection may fail.
Preparing the Cable
Once you have the appropriate length of cable, it’s time to prepare the ends. This is where a coaxial cable stripper comes in handy. A good stripper is designed to fit the wires and strip the ends efficiently. After stripping the cable, be sure to pull back the copper shielding. This step is crucial to prevent video signal problems.
To speed up this process, consider attaching a piece of Velcro to the back of your wire stripper. This makes handling the wire much easier than doing it by hand.
Making BNC Compression Connector Cables
Now that you’ve prepared your cable, let’s move on to making a cable with a BNC compression connector. Here’s a step-by-step guide:
- Put the BNC connector firmly onto the wire.
- Using the compression crimping tool, ensure you have the right adapter attached. The flat adapter is specifically for BNC connectors.
- Once you compress the connector, there’s no going back. If you mess up, you’ll need to start over, so take your time with this step. It’s advisable to order a few extra connectors for practice.
Congratulations! You’ve just made a cable with a BNC connector. This method provides a strong and reliable connection, essential for video signals.
Using Screw-On Connectors
The easiest cable to make is one using screw-on connectors. While they are simple to assemble, they are also the easiest to damage and are not weatherproof. Here’s how to make a cable with screw-on connectors:
- Strip the cable ends as previously discussed.
- Firmly insert the wire into the base of the connector.
- Twist the connector until it no longer turns. This will secure the connection.
While this method isn’t 100% weatherproof, you can enhance its durability. Sealing the base of the connector with self-adhesive rubber splicing tape will help prevent water ingress. This tape can be found in the electrical department of your local hardware store.
Crimp-On Connectors: A Challenging Option
Among the three types, using crimp-on connectors is often considered the most challenging. Similar to compression connectors, these are a one-time deal; if you mess up, you must start over. Here’s how to make a cable with crimp-on connectors:
- First, slide the crimping sleeve over the wire before stripping the cable. This makes the process easier.
- Strip the outer casing at about 2 cm, then pull down the copper casing.
- Strip the inner casing at about 1 cm.
- Insert the connector on the exposed wire in the center and ensure it is secure.
- Slide the crimping sleeve over the base of the BNC. Don’t worry about the copper shielding showing; you can clean it off later.
- Using the crimping tool, grip firmly at the base of the BNC and crimp the sleeve.
After crimping, don’t forget to cut off any exposed copper wires. This will help maintain a clean connection.
Now you know how to make video cables with BNC compression connectors, screw-on connectors, and crimp-on connectors. Each method has its pros and cons, but mastering these techniques will equip you with the skills needed for various projects, especially in the security industry.
