Design

When designing an electronic connector, manufacturers must consider several factors. First, they need to assess the environment in which the connector will operate, including:

• The components to which the connector must attach
• The range of ambient temperatures it will encounter
• The expected level of mechanical stress
• Compatibility with any existing connectors
• The frequency with which users will plug and unplug the connector

Based on these and other considerations, manufacturers will determine technical specifications such as pitch (the distance between the centers of separate connector contacts, both female and male), durability/mating cycles (how long the connector is expected to last under normal use), versatility, voltage type, and current type. Additionally, manufacturers must decide on the size and materials of the connectors.

To enhance the versatility of an electronic connector, manufacturers can incorporate custom features such as additional contacts, adaptability options, seals between the enclosure and insert to protect against oil, water, and moisture, corrosion-resistant anodized shells, and strain relief features, which prevent harmful mechanical forces from reaching the connector. Customization can also involve altering the number and types of pins. For more information on custom electronic connector design possibilities, consult your potential suppliers.

Features

There are various types of electronic connectors, but they generally consist of a few key components: contacts or terminals, housing, locking features, and keying features.

Contacts or terminals are the parts of the connector responsible for creating the connection. Male connector contacts are often referred to as “pinouts” because they typically consist of extended metal pieces resembling pins or prongs.

The contact system is one of the most crucial parts of an electronic connector, as it determines the density requirements, contact forces, and other mechanical characteristics of the connector.

Manufacturers almost exclusively make contacts and terminals from highly conductive, non-corrosive metals, such as phosphor-bronze, beryllium copper, modified copper, or brass.

Housings encase the contacts and protect them from exposure to or collision with external elements or people. Typically, housings are made from plastic, but sometimes manufacturers use dielectric or insulating materials instead.

Locking features are designed to secure a mating connection in place. Without these features, the connection could unintentionally disconnect.

Keying features, also known as polarizing features, ensure that connections can only be mated when properly aligned and oriented. This prevents users from incorrectly plugging in a connector and potentially damaging it.
