A wafer connector terminal is a crucial component in various types of electrical equipment such as printed circuit boards (PCBs) and electronic devices that require many connections. A wafer connector terminal is responsible for connecting multiple circuits on a single printed circuit board (PCB) in a very compact and efficient manner. It is also known as a "board-to-board connector" or a "housing connector". The connector has contacts that interface with the circuitry on a printed circuit board, while the housing provides mechanical support and proper orientation. The wafer connector terminal has contact spacing of usually 1.25 mm (0.049 in) for the conductor pitches, which makes it ideal for applications that require high-density packaging.
Wafer connector terminals are used widely in the electronics industry for various applications. They are used for connecting a variety of electronic components such as resistors, capacitors, and transistors. They are also used in applications such as multiple LED arrays, LCD displays, and other electronic devices.
Characteristics of Wafer Connector Terminal
1. Compact in Size
Wafer connector terminals are compact-sized because they have a small pitch size, which allows interconnection of a higher number of terminals within a small space.
2. High-density packaging
The wafer connector terminal is one of the packed interconnection technologies available in the market. It has a high-density packaging style, which allows the accommodation of a high number of connections per unit volume.
3. Easy Assembly
The wafer connector terminal has features such as locking mechanisms that make it easy to assemble, disassemble, and replace when necessary.
The wafer connector terminal has the flexibilities of connecting multiple components on a single PCB in a highly efficient and compact manner.
Wafer connector terminals are built with high-quality materials such as stainless steel, brass, and copper that make them highly durable, corrosion-resistant, and long-lasting.
Components of a Wafer Connector Terminal
The wafer connector terminal comprises several components, including the housing, contacts, shields, and locking clips.
A housing is the outer structure of a wafer connector terminal that provides a framework for the contacts in the connector. The housing can be made of plastic, aluminum or other materials. It has different sizes, shapes, and mounting options that are based on the number of contacts needed.
Contacts are the metallic parts of the wafer connector terminal that facilitate electrical connections between two terminals. It comprises an insert molded wire, a spring contact, and a bare wire that is welded together.
Shields are metal pieces that are placed around the contacts in the wafer connector terminal to minimize electrostatic discharge (ESD).
4. Locking Clips
Locking clips are plastic or metal strips that are used for locking the connector terminals in place.
Types of Wafer Connector Terminals
There are different types of wafer connector terminals available in the market that are used for various applications. Some of these types include:
1. Vertical Wafer Connector Terminal
This wafer connector terminal has a vertical orientation and is used where space is an issue, and the circuit size is limited.
2. Surface Mount Wafer Connector Terminal
The Surface mount wafer connector terminal is usually mounted in the surface of PCBs because of its low profile, making it ideal for cramped spaces.
3. Through-hole Wafer Connector Terminal
Through-hole type wafer connector terminal is used in applications where the PCB circuitry has or requires through-holes for leads to pass, especially when the soldering process is needed.
4. Right-angle Wafer Connector Terminal
The Right-angle-type wafer connector terminal is used when there is a need for a cable to enter the system at right angles to the PCB or other components. This type of connector is commonly used in audio, video, and communications equipment.
Applications of Wafer Connector Terminal
Wafer connector terminals are commonly used in various electronic applications. Here are some examples of their applications:
1. Personal Computers (PCs)
Wafer connector terminals are used in personal computers (PCs) to connect the computer's CPU to various peripherals such as the monitor, printer, and keyboard.
2. Motor Control Applications
Wafer connector terminals are used in motor control applications to connect multiple sensors to various control systems. This allows for the monitoring of the motor's speed and torque.
3. Automotive Industry
Wafer connector terminals are used in the automotive industry to connect various components of the engine and electronic control systems.
4. Telecommunications Industry
Wafer connector terminals are used in the telecommunications industry to connect communication systems, such as cell phones, telephone lines, and other electronic communication equipment.
Wafer connector terminals are an essential component in the electronics industry, especially for printed circuit boards (PCBs), where multiple connections need to be made within a small space. With their compact size, high-density packaging, and easy assembly, they have become a popular component in various applications, such as computer peripherals, automotive, telecommunications, and motor control systems. The versatility of wafer connector terminals has made them an indispensable part of many electronic devices, and innovation in design and development is expected to bring even more improvements in functionality and reliability.
