FPC (Flat Flexible) Connectors: HLW20R-2C7LF Application Field and Working Principle
Flexible Flat Cable (FFC) and Flexible Printed Circuit (FPC) connectors have exploded in popularity in electronic design, replacing any type of discrete wiring and offering a secure, cost-effective way of connecting large numbers of high-density assemblies. This article will discuss the application fields of a particular type of FPC connector, the HLW20R-2C7LF, as well as the connector’s working principle.
1. Application fields
The HLW20R-2C7LF is a type of FPC connector designed to meet stringent demands for reliable high-density mounting and mating. It is a vertical-style FPC connector that can handle up to 20 pins, and its main applications include computer system, notebook, and other digital products which require density applications, and where compaction and low profile height distance between FPC and PWB is necessary.
The HLW20R-2C7LF is designed with a slim body profile to deliver a height of only 3.1 mm in the mounted position. This makes it ideal for applications that require high-density while also leaving a small profile. On top of that, the connector is capable of withstanding 20 insertion/extraction cycles, ensuring repeatable connections with minimal wear and tear. The body has an inner metal cover to protect the spring sections so it can be used for longer periods of time.
The HLW20R-2C7LF also features a robust low-insertion force mechanism which makes it easier to connect, regardless of the position of the device. In addition, the connector has a secure retention mechanism to ensure that the FPC is firmly held in place for maximum reliability. The connector is also designed with a mounting structure that increases stability by reducing the torque generated by the weights and forces of the FPC.
2. Working Principle
The working principle of the HLW20R-2C7LF is based on the male-female connection formed between its two main components: the contacts and the FPC. When the FPC is inserted into the connector, the male pins enter the mating holes of the FPC to establish an electrical connection. The friction between the pins and the mating holes creates a secure mechanical connection that ensures reliable and consistent contact for the duration of the connection.
The HLW20R-2C7LF is designed with a robust spring-loaded arm that helps lock the FPC into place and provides a secure and reliable connection. The latch arm has a dual-axis mechanism that helps secure the FPC in both lateral and rotational directions, so that it stays firmly in place even when exposed to physical stress or external forces.
Moreover, the connector is designed with a low-profile lock mechanism that is recessed so the FPC is not pushed out when the latch arm is engaged. This ensures that the connector can withstand repeated mating and unmating cycles with minimal wear and tear.
In sum, the HLW20R-2C7LF is a type of FPC connector designed for high-density applications where a small profile is required. It features a secure retention mechanism, robust spring-loaded latch arm, and a low-profile lock mechanism to ensure reliable and consistent electrical connections.
