CHTAR are manufacturer of heavy duty connectors. CHTAR supply full sets of heavy duty connectors. Insert Heavy Duty Connectors also named internal terminals or contacts in heavy duty connectors. They are the core electrical and mechanical interface of heavy duty connectors. They house the individual male (pin ) and female (socket) contacts that make the actual electrical connection.
Insert Heavy duty connectors typically made from high-conductivity brass pins and plated with silver. Silver plaiting is common for signal contacts for reliable low-voltage mating, while is used for higher-power contacts due to its excellent conductivity and cost-effectiveness.

CHTAR are manufacturer and factory who produce components by ourselves. We design in our factory. We design precision-engineered with specific geometries. Common types include standard pin&socket. The crimp contacts is gas-tight connections to wire strands, screw clamp contacts is for solid and stranded wires, allowing tool-less or simple screwdriver termination. Spring cage contacts is utilized a tension spring for fast, reliable, and vibration-proof wire insertion.
CHTAR supply different pins of insert heavy duty connectors. There are different pins connectors. They are 3, 4, 5, 6, 10, 16, 24, 32 and 48 and so on. They will be assembled in different type of housing or shell of heavy duty connectors to protect working.
Insert Heavy duty connectors or terminals inside are often individual components inserted into modular insulator housings within the mail shell. This allows for custom configurations mixing power ,signal,data,and even coaxial or fiber optic contacts in a single connector. The insert terminal block and individual contacts are designed with specific shapes and positions to ensure correct mating and prevent misplugging.
They will be made in gray color what will be control color and the color matching is done during the raw material preparation stage.
Insert heavy duty connectors are working to supply a low-resistance,reliable path for electrical current (power) or signals between the cable and the mating connector equipment. To physicallyy secure the wire or PCB lead, ensuring the connection remains intact under vibration, shock and repeated mating cycles. They creates a standardized ,repeatable interface between equipment or cable harnesses, simplifying manufacturing and maintenance. The insulating housing around the terminals provides electrical isolation between poles (preventing short circuits ) and protects the contacts from physical damage during handling.

Insert heavy duty connectors advantages are high reliability and safety, excellent current carrying capacity, vibration and shock resistance, long service life& high mating cycles, ease of installation and maintenance and flexibility design. The insert terminal section of heavy duty connectors transforms the rugged external aluminum housing into an intelligent, flexible, and supremely reliable electrical interface. It is the key component that enables the HDC’s core benefits of reliability, modularity, and ease of use in demanding applications.
CHTAR is ready to supply competitive prices and good quality connectors.
