Introduction

The ESQ-135-23-L-S is a type of rectangular connector used for connecting electroniccircuits and components. It is a header, which is a female socket that typically carries signal and power lines. Connectors such as the ESQ-135-23-L-S are used in applications that require quick and easy electrical connections, such as data processing centers, automation systems, and portable devices. This article presents an overview of the different types of rectangular connectors and their applications, along with the working principles behind them.

Rectangular Connectors and Their Applications

Rectangular connectors (also known as rectangular plugs and sockets) are used to connect various electronic components and circuits. They are designed to allow for easy, reliable and repeatable connections. These connectors exist in a wide range of shapes and sizes, with varying contact counts. The most common shape is the rectangular connectors that are used in consumer electronics, computers, and medical & industrial applications.Consumer applications include devices like televisions, DVD players, game consoles, and home theater systems. Computer applications include laptops, desktops, tablets, and networks. Industrial applications include robots, machines, and process control equipment. Medical applications include imaging, laboratory, and surgical equipment.When it comes to rectangular connectors, the contacts come in two forms: pins and sockets. Pin contacts are typically CPU pins, whereas sockets are generally ribbon cables, board-to-board connectors, printed circuit boards (PCBs), and even spread-out soldering interconnects. In most cases, rectangular connectors are designed to ensure the highest reliability when used in harsh environments. For example, the ESQ-135-23-L-S is designed to protect against dust and liquids as well as provide a firm and secure connection.

Working Principle Behind Rectangular Connectors

The working principle behind rectangular connectors is based on metal spring contacts (pins and sockets). The pins move independently against each other and establish electrical contact whenever they are correctly aligned. This ensures reliable and repeatable electrical connections that can withstand vibration and temperature changes.To ensure the highest reliability and prevent contact damage, most rectangular connectors are designed with two types of protections: mechanical and electrical. Mechanical protection is provided by the connector’s housing, which is made of rigid materials such as metal, plastic, or rubber. Depending on the application, the housing can also be insulated to provide additional protection against electric shocks.The electrical protection is provided by the contacts, which are specifically designed for high-speed connections. To ensure high-speed transfer rates, the contacts need to be resistant to corrosion, oxidation, and wear.

Conclusion

The ESQ-135-23-L-S is a type of rectangular connector used in various applications. It is designed to provide reliable and repeatable electrical connections, and is protected against dust and liquids. The working principle of rectangular connectors is based on the contact between two independent pins. To ensure the highest reliability, these connectors are designed with both mechanical and electrical protections.
