Ribbon Wire Cable Structure
Flat Design
A ribbon wire cable is flat and wide. It looks like a thin strip, like a ribbon. This shape helps it fit into small spaces in computers. The cable bends easily. You can move it around corners or under parts.
Tip: The flat shape keeps wires neat and stops mess inside devices.
The flat design changes how signals move in the cable. Ribbon wire cables carry signals well for short distances. They work best at low frequencies. When return wires are between signal wires, they work better. At high frequencies or with lots of electrical noise, round cables protect signals more. Ribbon wire cables are best for short runs where you need flexibility and neatness.
Here is a table with common sizes for ribbon wire cables:
| Parameter | Value |
|---|---|
| Conductor Gauge | 28 AWG (stranded 7/36 strands) |
| Number of Conductors | 20 conductors |
| Cable Width | 26.92 mm |
| Insulation Thickness | 0.030 inches (extruded flame retardant PVC) |
| Pitch Between Conductors | 0.050 inches (1.27 mm) |
| Overall Cable Thickness | 3 mm |
| Voltage Rating | 300 V |
| Operating Temperature | -40°C to 105°C |
| Insulation Material | PVC (Polyvinyl Chloride) |
Parallel Conductors
Inside a ribbon wire cable, many wires run side by side. They stay in one layer. The wires do not twist or cross. Each wire carries its own signal. All wires stay parallel from end to end. This makes it easy to connect many places at once. That is why ribbon wire cables are used in computers and printers.
The space between wires is called pitch. Most ribbon wire cables use a pitch of 0.050 inches (1.27 mm). This matches the pins on standard connectors. Some cables use other pitches, like 1.00 mm or 2.54 mm, for different devices. The table below shows common wire spacing:
| Typical Conductor Spacing | Equivalent Metric Value | Common Application / Notes |
|---|---|---|
| 0.05 inch | 1.27 mm | Most usual spacing; matches IDC connector pin spacing |
| 1.00 mm | 1.00 mm | Used in floppy disk drive cables and some custom ATA cables |
| 2.54 mm (0.1 inch) | 2.54 mm | Standard pitch for many ribbon cables, aligns with two-row connectors |
Note: The parallel layout makes it easy to match with connectors. But it can pick up electrical noise if used for long distances.
Materials and Connectors
Manufacturers use special materials to make ribbon wire cables strong. The wires inside are usually copper. Copper carries electricity well. The insulation protects the wires and keeps signals apart. Common insulation materials are:
- PVC (Polyvinyl Chloride)
- Polyethylene
- Teflon (PTFE)
- Polyolefin
These materials help the cable resist heat, chemicals, and bending. Some cables use advanced materials for better performance. These are used in high-speed or high-temperature places.
Ribbon wire cables connect to devices with special connectors. The most common types in computers are:
- DB25 connectors
- DB9 connectors
- DB15 connectors
- Centronics 50 connectors
- IDE type connectors
- IDC 2×17 connectors
These connectors let the cable snap in fast and tight. The flat cable matches the connector pins. This makes installation easy and safe.
Tip: Manufacturers test ribbon wire cables by bending them and checking for breaks. They also check the insulation and connectors. This makes sure the ribbon wire cable will last a long time.
Ribbon Cable Types
Standard Ribbon Cables
A standard ribbon cable has many wires in a flat strip. The wires run next to each other. Most standard ribbon cables look gray. They work best for short distances. These cables do not have extra shielding. They fit well where EMI is not a problem. Many computers and printers use them inside. The flat shape lets you connect many wires at once.
Standard ribbon cables are light and bend easily. They cost less than shielded cables and are quick to install.
The table below shows the differences between standard and shielded ribbon cables:
| Feature | Standard Ribbon Cable (Unshielded) | Shielded Ribbon Cable |
|---|---|---|
| Construction | Multiple parallel conductors without additional shielding | Conductors surrounded by a conductive layer (foil or mesh) |
| Purpose | Used where EMI is not a significant concern | Protects against EMI and external interference |
| Flexibility and Weight | Lightweight and flexible | More robust and less flexible |
| Typical Use | Short distance, low EMI environments | High-speed, sensitive data transmission, high EMI areas |
| Cost | Cost-effective | Generally more expensive due to shielding |
Shielded Ribbon Cables
Shielded ribbon cables have a special layer around the wires. This layer can be foil or metal mesh. The shield blocks outside electrical noise. It keeps the signals inside safe. Shielded ribbon cables work best in places with lots of EMI. Factories and data centers use them often. These cables are thicker and bend less than standard ones. They cost more and need careful setup.
| Aspect | Shielded Cables | Unshielded Cables |
|---|---|---|
| EMI Protection | Has a conductive barrier that conducts noise to ground | No physical shield present |
| Noise Immunity | Better in high-EMI environments | Can perform well if designed properly |
| Installation Considerations | Heavier, less flexible, requires grounding | More flexible, easier to install |
| Risk Factors | Improper grounding can cause problems | Less risk of unwanted noise pickup |
| Typical Use Cases | Industrial, high-EMI areas | Office, low-EMI areas |
Bonded ribbon cable is a kind of shielded ribbon cable. The wires are stuck together with strong glue. This keeps the wires in place and makes the cable stronger. Bonded ribbon cable works well in tough places.
Color-Coded Ribbon Cables
Color-coded ribbon cables make wiring and repairs faster. Each wire has a different color or a stripe. The first wire often has a red or blue stripe. This shows where to start connecting the cable. Color coding helps match each wire to the right pin.
- Color-coded ribbon cables help stop mistakes when installing.
- The colors help people find and fix problems fast.
- A multimeter can test each wire for breaks or wrong spots.
- Notches and color stripes help avoid errors together.
