HLW22R-2C7LF Application Field and Working Principle

Flat Flexible Connectors (FFC, FPC) are electrical connectors designed to provide electrical connectivity in a range of industries from consumer electronics, medical equipment, computer and communications, automotive, and more. They are distinctly different from standard wire-to-wire and board-to-board connectors in that they provide a reliable, interference-free link between two rigid surfaces, enabling them to be used in designs where traditional connectors are not suitable.The HLW22R-2C7LF is one example of flat flexible connectors, which is designed to provide high current-carrying capability in high speed, low-impedance, and high reliability applications. The HLW22R-2C7LF connector is typically used in a variety of high current or power distribution applications including processor-based systems, power supplies, and I/O interfaces. Additionally, it is also designed for harsh environments that demand reliability, vibration resistance, EMI / RFI shielding, flexibility, durability, and value.

HLW22R-2C7LF Design and Features

The HLW22R-2C7LF flat flexible connector consists of two mating components: a male header with solder pins and a female receptacle or housing. The female receptacle is constructed with a unique, low-insertion-force, highly reliable flex circuit technology that reduces soldering time while improving connection reliability. The flex circuit is made of two conductive layers and a dielectric layer that are laminated together and secured to a flexible PCB. The male header is composed of a one-piece stamped metal housing containing multiple solder pins for reliable electrical connectivity.The HLW22R-2C7LF connector features a dual-contact mating design for superior signal integrity and reliability in high-performing applications. The contacts are staggered for zero-deflection force mating, and are engineered to securely clamp onto the flex circuit for improved signal integrity and vibration resistance. Additionally, the dual-contact design prevents accidental disconnect which is particularly important in high current applications. The connector is also filled with special high-dielectric material which provides superior EMI / RFI shielding.

HLW22R-2C7LF Working Principle

The HLW22R-2C7LF flat flexible connector enables a reliable electrical connection between two rigid surfaces without the need for wires or cabling. The connector is designed so that components can be connected without soldering or crimping. The male header and the female receptacle are mated together by simply inserting the male header into the female receptacle. This is done by first aligning the male header with the female receptacle, then pushing the male header in until it reaches the connector\'s stop point. The dual-contact design of the connector ensures that the pins and contact areas are securely in place once the connector is mated.Once the male header and the female receptacle are connected, the contacts on the male header make contact with the flex circuit of the female receptacle, enabling the connection of components within the housing. The connection established creates a low-resistance electrical connection with superior signal integrity and interference-free performance. The high-dielectric material used in the connector provides superior EMI/RFI shielding, thereby making sure that the connection is robust and reliable.

Conclusion

The HLW22R-2C7LF flat flexible connector provides a reliable, high-performance connection between two rigid surfaces. It is designed for harsh environments and features dual-contact mating, zero-deflection force mates, and superior shielding for superior signal integrity. It is ideal for high current or power distribution applications in industries such as consumer electronics, medical equipment, computer and communications, automotive, and more.
