Four Methods to Separate Flight Control Wiring Harnesses in an Aircraft

Posted by John Ashour on August 6, 2018

The F-16 like many aircraft is a “fly by wire” aircraft. Instead of cables and pulleys, the aircraft is controlled by electrical signals. The electrical signals tell the flight control surfaces how to move and how fast to move. There are 5 flight control surfaces on the F-16: (1) leading edge flap, (2) trailing edge … Continue reading “Four Methods to Separate Flight Control Wiring Harnesses in an Aircraft”

Why is Connector Polarization Important in Wiring Harness Design?

Posted by Mike Winters on July 23, 2018

When designing aircraft wiring harnesses, or, in fact, any wiring harness, the main purpose of a wiring harness is to transmit signals or electrical power between components in a system.  However, this cannot be achieved unless the wiring harness can physically connect to these components. There are several ways to make these connections but probably … Continue reading “Why is Connector Polarization Important in Wiring Harness Design?”

What are Connector Disconnects and Why are They Needed?

Posted by David Barnett on July 16, 2018

There are many types of Connector Disconnects in use today in the aircraft industry, from blade to plug and socket.  From here they split into even more types based on their class, size, contact arrangement number and style. Depending on the combination of these variations, they can effectively send and receive data, signals and voltages … Continue reading “What are Connector Disconnects and Why are They Needed?”

Factors to Consider When Choosing a Backshell Disconnect

Posted by Randy Harmon on May 22, 2018

The process for choosing the correct backshell at an electrical component or disconnect whether it be for the F-16, F-15, F-22, B1-B, Cobra, Huey, or any new aircraft, follow the same basic guidelines. The key to successful backshell selection begins with identifying the application. To do this, a complete description of the backshell’s intended use … Continue reading “Factors to Consider When Choosing a Backshell Disconnect”

How Many Empty Contact Cavities Should a Disconnect Have?

Posted by Nam Tran on May 13, 2018

Connectors are used on electrical wiring harnesses or panels… and installed in aircraft. Connectors can be round (e.g. D38999 Series), flat (e.g. 16VE0490 Series) or rectangular (e.g. M83733 Series). They’re used to permit connection or disconnection of single or multiple electric circuits to facilitate communication, control, calibration, troubleshooting, replacement of parts and equipment. Connectors have … Continue reading “How Many Empty Contact Cavities Should a Disconnect Have?”

What is a Contact Cavity?

Posted by Clare McGarrey on August 16, 2016

Do I need to see a dentist? Do I need to see a doctor? No. In our field of expertise, all you need to do is see an assembler. I looked up the word cavity and it said, “A cavity is a hollow in an object.” So, if you are at a dentist office, a cavity … Continue reading “What is a Contact Cavity?”

What is an Insert Arrangement?

Posted by Eric Evans on July 4, 2016

The highly advanced military aircraft of today, such as the Lockheed Martin F-35 fighter or Boeing B-1 bomber, contain a large amount of specialized electrical equipment. Some examples include relay panels, circuit breaker panels, mux transformer panels, audio panels, navigation computers, weapons computers, and many more. This equipment is essential in enabling the aircraft to complete its designed mission, … Continue reading “What is an Insert Arrangement?”

What is a standard part versus a non-standard part?

Posted by Chris Vardy on April 11, 2016

In the 1980’s, the fast food chain Wendy’s had a commercial advertising chicken sandwiches with a tag line stating “parts are parts”. InterConnect Wiring has been assembling wiring harnesses and electrical panels with both standard parts and non-standard parts for the past 23 years. But parts are parts, right? When the Department of Defense started … Continue reading “What is a standard part versus a non-standard part?”

Why is it better to Use Military Connector Part Numbers Instead of Commercial Part Numbers When Either Designing New Aircraft or Updating Existing Aircraft?

Posted by Clare McGarrey on March 14, 2016

InterConnect has been designing and assembling aircraft electrical wiring harnesses now for over 23 years. During this period, we have seen a number of design mistakes dealing with electrical connectors. The biggest mistake is that a customer begins to callout vendor part numbers instead of military connector part numbers on the Bill of Materials (BOM). … Continue reading “Why is it better to Use Military Connector Part Numbers Instead of Commercial Part Numbers When Either Designing New Aircraft or Updating Existing Aircraft?”
