Rectangular Connectors
Rectangular connectors are standardized interface devices used to transmit power, signals, or data. Their shells are rectangular or square in design and have multiple regularly arranged contact terminals. They are commonly used in industrial equipment, aerospace, energy, and electronic equipment.
1. Rectangular Connectors Overview
Appearance Features: Different from circular connectors, rectangular connectors are designed based on rectangular geometry and are suitable for scenarios that require multiple pins or compact arrangements.
Sub-types: According to international standards (such as IEC TR 62380), rectangular connectors can be classified in parallel with other types (such as circular and coaxial connectors), and their failure calculation methods are consistent.
2. What are the Technical Characteristics of Rectangular Connectors?
1)Combination Design: The typical structure includes a plug (male end) and a socket (female end), and keyed alignment is used to ensure the correct plugging direction, such as by fixing with locking screws to improve connection stability.
2) Performance Parameters:
Electrical Characteristics: The operating voltage can reach 954 VDC, the terminal rated current is up to 5A, and the contacts are gold-plated to improve conductivity and corrosion resistance.
Mechanical Properties: Supports vertical PCB installation, and the shell material is mostly nickel-plated to meet the durability requirements in industrial environments.
3. What are Rectangular Connectors Used for?
Industrial Scenarios: Widely used in industrial automation, communication equipment, and power systems, such as connecting sensors, controllers, and actuators.
Electronic Equipment: As a board-to-board connector (Board-to-Board or Wire-to-Board), it serves the internal circuit interconnection in the fields of computers, medical equipment, etc.
4. Typical Product Examples for Rectangular Connectors
Standardized Products: Such as TE Connectivity’s CY8561 series, which includes a female end housing kit and a keyed alignment interface, supports wire-to-wire connection, and is suitable for EME installation environments.
Industrial-grade Components: Lear Corporation’s 18280.050.000 model demonstrates the adaptability of rectangular connectors in automotive electronics and complex electrical systems.
5. Customization and Compatibility of Rectangular Connectors
Some manufacturers (such as TXGA) provide customization services, which can adjust the contact termination form (such as crimping, welding) or protection level according to specific application conditions (such as high temperature, sealing requirements), shortening the development cycle.
