Reliable electrical connectors are critical in vehicles, connecting various electrical systems such as engine control units, sensors, and communication networks. The automotive industry demands connectors with robust environmental resistance, preventing failures caused by temperature fluctuations, vibrations, and exposure to chemicals.

Aerospace Industry

In the aerospace sector, reliable connectors are vital for the safe and uninterrupted operation of mission-critical equipment and systems. Connectors used in aerospace applications must meet stringent standards for durability, electrical performance, and resistance to extreme temperatures, shock, and vibration.

Telecommunications Industry

With the increasing demand for faster and more reliable communication networks, dependable electrical connectors are crucial in the telecommunications industry. Connectors used in fiber optic cables and high-speed data transmission must offer low insertion loss, high bandwidth, and strong mechanical stability to ensure efficient data transfer and network performance.

Industrial Applications

In industrial settings, reliable electrical connectors play a fundamental role in powering and controlling machinery and equipment. Connectors used in industrial applications must withstand heavy-duty operations, while ensuring secure and stable connections to prevent downtime and optimize productivity.

Components of Connector

Shell

The electrical connector shell refers to the housing, nut, and tail attachment of the plug and socket. The role of the shell is to protect the internal parts of the insulators and contact bodies from damage. The positioning keyway is for the plug and the socket, and the nuts are used to connect and disconnect the socket. The tail attachment is used to protect the connection point of the wire and the contact body from damage and also used to fix the cable.

The shell also has a certain electromagnetic shielding effect. It is generally made of aluminum alloy through machining, cold extrusion, die casting. Steel shells are mostly used for glass sealing and high-temperature resistant electrical connectors.

Insulator

The insulator consists of a pin insulator, jack insulator, interface seal body, and line seal body, etc. It is used to keep the pin and jack at the set position and create electrical insulation among each contact body and between the contact body and the shell. The interface seal body and line seal body are added to the insulator to improve the environmental resistance of the electrical connector.

In order to achieve high-temperature and low-temperature resistance, flame retardancy, and ensure the stability of the geometric dimensions of parts, most insulators are molded from thermoset plastic, and the interface seal body and the line seal body are molded from silicone rubber.

Contact Body

The contact body includes a male contact piece and a female contact piece sometimes called a pin and a jack. And the connection methods are divided into the welding type, the crimping type, the press-in type, and the winding type, etc., to realize circuit connection.

The pin and the jack are the key component of the electrical connector, which directly affects reliability. Most of the pin and jack are machined from elastic copper alloy materials with good conductivity, and the surface is silver-plated or gold-plated to achieve low contact resistance and anti-corrosion. Generally, there are slotted jack, wire spring jack, crown spring jack, and punched jack.

What are the Common Electrical Connector Materials?

Brass

Brass is the cheapest metal you can use in terms of weight. Generally, the zinc content in brass can range between 5% to 40% based on the application. Brass offers considerable strength, good spring and adequate electrical properties.

Brass connectors are mainly used for KK terminals.

Phosphor Bronze

Phosphor bronze is tough and offers increased strength compared to brass. It comes with impressive conductibility and superior fatigue resistance. Phosphor bronze also has excellent elasticity making it suitable for use in electrical contact springs.

Beryllium Copper

Beryllium copper is the best type of copper alloy for spring terminals. It contains around 0.5% to 3% beryllium with other elements. The alloy offers high strength and is cheaper than phosphor bronze.

High Copper Alloy

High copper alloys contain a high percentage of copper (more than 96%) and are suitable for demanding applications. The alloys have high strength coupled with excellent thermal and electrical properties. You can also use them in high-temperature settings as they don’t soften easily.

How Do You Maintain Connector?

Regular Inspections

Regularly inspect your connector for signs of damage or wear, such as cracks or breaks in the housing. Ensure all contacts are secure and undamaged Check to see if the over-molding is working to protect your connection system as it was intended (e.g. water resistant).

Cleaning

Establish a cleaning schedule to remove any accumulated dirt, dust, or debris is important. Use a soft-bristled brush or a lint-free cloth for this purpose, and avoid using abrasive cleaners or solvents that could potentially harm the connector.

Protection

Protect your connector from moisture and other environmental elements that could cause corrosion or damage. When not in use, store your connector in a dry, cool place and use protective caps.

The Considerations for Buying

Environmental Protection

Depending on your electrical project, the connection may require additional environmental protection from external factors. For example, harsh environments can expose connectors to extreme weather. So, it is important to look for electrical connectors that can create the type of seal you need for your circuit.

Whether you are looking for weatherproof, waterproof, or UV resilient, these considerations will influence the choice of your connectors. Typically, heat shrink wire connectors and heat shrink connector kits are preferred for their environmental protection features, keeping rain, wind, and more at bay.

Durability

Electrical connectors must be resistant. If they are part of a permanent circuit, they need to be able to remain in place even when exposed to some tugging, stretching, or any other external pressure.

Here again, the focus is on working with electrical connectors that can guarantee a tight and secure connection designed for long-term usage. This is where heat shrink connectors can elevate your installation.

Ease of Installation

Essentially, electrical connectors need to be easy to use.

Frequently Asked Questions

Q: What are Application of Connectors?

A: As we have seen, there are a lot of Connector types. Because there are so many different types of Connectors, they tend to have unique roles. We will now see some unique applications of Connectors.

You can find Connectors on every computer and laptop.

We are all aware of the Universal Serial Bus, also known as USB, which is also a standard Connector.

Connectors are also used as radio frequency Connectors. These Connectors help prevent the change of the transmission line’s impedance.

The Connectors named eight positions/ eight conductors (8P8C) are used in ethernet cables and CAT5. They look like RJ45 cables but the socket of 8P8C is different from RJ45.

D-Subminiature is the Connectors used in modem ports and IBM-compatible computers. There are different types of D-subminiature Connectors. These are thermocouple contact options, PCB and crimp mounts, solid machined contacts, etc.

The DC Connectors and AC power sockets/ plugs are installed to prevent people from getting shocked when they come in contact with energized conductors.

Q: What are the connection methods of electrical connector?

A: Welding

The most common type of welding is tin soldering, and the most important thing for it is the continuity between the solder material and the soldered surface. Therefore, for electrical connectors, solderability is important.

Tin alloys, silver, and gold are the most common coatings on the soldering end of connectors. The reed contact pair has a welding end of solder tab, punching solder tab, and notched solder tab type, while the pinhole contact has a drilled arc notch type for the common welding end.

Crimping

Crimping is a technique to connect wires to contact pairs for compressing and displacing metal within the limits. Good crimping can produce intermetallic fusion flow so that the wires and contacts material deform symmetrically. This kind of connection is similar to a cold welding connection, which can get better mechanical strength and electrical continuity, and can withstand more severe environmental conditions.

At present, it is generally believed that crimping is better than soldering, especially on high-current occasions. Special crimping tools or automatic or semi-automatic crimping machines must be used in crimping. And the wire barrel should be selected correctly according to the cross-section of the wire. It should be noted that crimping is a permanent connection and can only be used once.

Winding

Winding is to wind the wire directly on the winding post of the angular contact. The wire is wound under the tension, and pressed into and fixed at the corners of the winding post to form an airtight contact. There are several requirements for wire winding.

the nominal value of the wire diameter should be in the range of 0.25mm -1.0mm;

when the wire diameter ≤ 0.5mm, the elongation of the conductor material is ≥ 15%;

when the wire diameter is > 0.5mm, the elongation of the conductor material is ≥ 20%.

Tools for winding include wire wrap tools and fixed winding machines.

Puncture Connection

Puncture connection, also known as insulation displacement connection(IDC), is a novel end technology invented in the United States in the 1960s with high reliability, low cost, and ease of use. It has been widely used in various electrical connectors for printed boards and is suitable for the connection of ribbon cables.

It is not necessary to strip the insulation layer of the cable during the connection, instead, penetrate the tip of the U-shaped contact spring of the connector into the insulation layer to make the cable conductor slide into the groove of the contact spring and be clamped so that a tight electrical connection is formed between them. It requires only simple tools but must use cables with a specified wire gauge.

Q: How do you remove pins from electrical connectors?

A: If you need to remove pins from a connector, there are a few things you'll need to do. First, find a small screwdriver that fits into the pin's slot. After that, locate the tab that holds the pin in place and gently pry it up. Once the tab is lifted, the pin should come out quickly.

Q: What are the essential features of connectors?

A: Some of the basic features for a good connector are reliability and low cost, high return and low insertion losses, easy to operate and install and low sensitivity for environmental conditions. These connectors also help in quicker disconnection and connection and align at the cores to allow light to pass through it.

Q: What factors should be considered when purchasing an electrical connector?

A: Cost

Cost is usually an important consideration for many engineers and manufacturers. After all, you want to have the best at the lowest price possible, right?

Even that is your goal, don’t make the mistake of choosing your connectors based on the only cost. You may end up with cheap products which don’t do their job and lead to the failure of your project.

So always look for quality and try to strike a balance with cost to enjoy the maximum cost-effectiveness.

Electrical connector–Environment

The environment where you will use the connectors is also crucial. Will the connectors be used on bare ground or in the water? Or in a boat? Will the connectors encounter extreme weather? Will the project involve vibrations and shocks?

Select the best connectors based on your use environment. You should go for connectors with environmental sealing if you need protection against dust, vapor, liquids or combustible gases.

Determine the level of safety you require and then choose the connectors. Also, keep the operating temperature range in mind while making your selection.

Signal Type

You will need to choose the connectors based on the signal they transmit. Signals can be analog, digital, or a combination of both. If the signal is analog, then what is the frequency? Does it involve audio or RF? What is the bit rate or clock speed for analog signals?

The type of signal decides the type of connector, pinout, and wiring you will need.

Remember that you cannot use certain signal combinations in the same connector. You will need to consider clearance distances and creepage for high-voltage pins. You can also go for a custom solution based on your unique needs and design specifications.

Power Level

The level of current passing through your connector will also influence your choice. For high current paths, you will need multiple larger and thicker pins. If you are dealing with high voltage, then go for a connector with more insulation. For high voltage pins, you may also need to consider clearance distances and creepage.

Ruggedness

The frequency of your terminals determines the strength of the connectors you need. Will the terminal be often plugged in and plugged out? Choose a connector with appropriate ruggedness based on your application.
