Rectangular connectors, also referred to as headers, male pins, and ribbon, are devices used for connecting and routing electrical signals and power, which are integral to modern electronic systems. The HTSW-118-08-F-S-RA connector from Hirose Electric Co., Ltd is a type of single row male mini-pin right angle (RA) series connector designed to enable easy signal transmissions and power connections. This article seeks to explore the HTSWR-118-08-F-S-RA application field and working principle.

Application Field

With its 3.45mm centerline pitch, the HTSW-118-08-F-S-RA is ideal for board-to-board and wire-to-board applications in the automotive and computing industries—particularly in applications involving tight styling requirements. It features a low profile of just 8.25mm, making it an ideal solution for PCBs (printed circuit boards) with limited build space. The compact design also makes the connector suitable for portable devices and applications where space is limited.

The HTSW-118-08-F-S-RA can handle effective signal transmissions up to a 9.42A. It is rated up to 10kHz and can simultaneously support both AC and DC signals. It also features a unique blocking construction, which holds mating connectors securely to prevent vibration-induced misalignment. This adds to the reliability and durability of the device, allowing it to stand up to harsh environments and conditions.

Working Principle

The working principle of the HTSW-118-08-F-S-RA can be divided into two general steps. The first step refers to the electrical connection between the two components. The second step refers to preserving the integrity of the connection itself, through a process of contact protection. In the first step, the male pin header mates with a female socket, creating an electrical connection between the two components.

The positive and negative terminals of the male pin header are then lined up with the appropriate pins of the female socket. The pins must be lined up and inserted correctly in order to create the desired electrical connection. After this first step is completed, the second step involves the process of contact protection. This involves a series of steps that is designed to keep the pins from moving or disconnecting from the female socket due to vibration, shock, or another external force.

One way to protect the connection is through the use of a wire spring clip. This clip provides a releasable yet secure connection between the two components. The clip is inserted through the female socket and mounted on the male pin header. When the clip is installed, it forms a solid contact between the male pin header and the female socket. This helps to maintain the integrity of the connection and prevents accidental disconnection.

The HTSW-118-08-F-S-RA series connector is a reliable and robust solution for board-to-board and wire-to-board applications. Its design complies to both industrial and automotive standards, making it an ideal choice for many applications. The compact size and low profile allow users to install the device with minimal effort, while the contact protection feature helps to maintain the long-term integrity of the connection.
