Rectangular Connectors - Free Hanging, Panel Mount are two types of connectors that enable efficient and flexible connections between electronic devices and systems. The free hanging type is suitable for scenarios that require flexible wiring or limited space. It is directly suspended and connected through cables for easy installation and maintenance. The panel installation type is designed specifically for fixed installation on equipment panels, secured with screws or other fasteners to ensure a stable and reliable connection. This type of connector typically consists of an insulated housing, conductive contacts, locking mechanisms, and protective devices, among other components. It offers advantages such as flexible installation, high transmission rate, and low contact resistance.

Rectangular Connectors - Free Hanging, Panel Mount are widely used in various fields. In the communication industry, they are commonly used for internal and external connections of devices such as base stations, switches, routers, etc. In the field of industrial automation, rectangular connectors serve as a bridge between devices such as PLCs, sensors, and actuators. In data center servers, rectangular connectors installed on panels are used to connect servers to power distribution units, achieving efficient and stable power supply. In automotive electronic systems, freely suspended rectangular connectors facilitate flexible layout and quick maintenance of complex wiring harnesses inside the vehicle.

• 1. Common packaging methods for rectangular connectors?

  1. Panel-mounted packaging
  Panel-mounted packaging is the most common form of rectangular connector, which allows the connector to be directly fixed to the housing or panel of the device. This packaging method is usually achieved by screw locking, snap-on fixing or crimping to ensure a stable connection between the connector and the panel. The advantages of panel-mounted packaging are easy and quick installation, easy maintenance and replacement, and good mechanical strength and protection level. It is suitable for scenarios that require frequent plugging and unplugging or high protection requirements, such as industrial control equipment, communication equipment, medical equipment, etc.
  
  2. PCB Mounting Package
  PCB mounting packaging is another widely used rectangular connector packaging method. It directly solders the connector on the PCB (printed circuit board) and realizes electrical connection through pins or pads. This packaging method has the advantages of small size, light weight, flexible layout, etc., which can save space to the maximum extent and improve the integration of the circuit board. It is widely used in computers, consumer electronics, automotive electronics and other fields, especially in occasions with extremely high space requirements, such as mobile phones, tablets and other portable devices.
  
  3. Pin header and socket combination packaging
  The pin header and socket combination packaging is a packaging form in which the two parts of the connector (pin header and socket) are designed separately and then electrically connected by plugging. This packaging method is easy to plug and unplug and easy to replace and upgrade, and is particularly suitable for scenarios where frequent module replacement or system upgrade is required. For example, in the fields of test equipment, modular data centers, etc., the pin header and socket combination packaging can significantly improve the flexibility and maintainability of the system.
  
  4. Mixed packaging
  With the continuous development of electronic technology, a single packaging method has been difficult to meet the complex and changing application requirements. Therefore, mixed packaging came into being, which combines multiple packaging methods to form a comprehensive solution. For example, combining panel mounting with printed circuit board mounting not only ensures the stability of the connector, but also improves the integration of the circuit board; or combining the pin and socket combination with modular design to achieve a more flexible and changeable system configuration.
  
  5. Special environmental adaptability packaging
  In some special environments, such as high temperature, low temperature, high humidity, strong electromagnetic interference, etc., higher requirements are placed on the packaging method of rectangular connectors. To this end, a variety of special environmental adaptability packages have been developed, such as high temperature resistant packaging, waterproof packaging, anti-electromagnetic interference packaging, etc. These packaging methods improve the environmental adaptability of the connector by using special materials and optimizing structural design, ensuring that it can still work stably and reliably in harsh environments.

• 3. What is a rectangular connector?

  A rectangular connector is a connector with a basically rectangular shape and a basically rectangular mating surface. It is also an important category in the connector family. There are many varieties and specifications, and it is also widely used. It should be pointed out that the classification of rectangular connectors and printed circuit board connectors, strip connectors, and ribbon cable connectors is sometimes not strictly defined. For the same type of connector, some manufacturers classify it as a rectangular connector (approximately rectangular in shape), some as a printed circuit board connector (used in printed circuits), some as a strip connector (approximately long in shape), and some as a ribbon cable connector (connected with a ribbon cable). It is widely used in indoor cable connections, internal connections of equipment, and occasions where multiple rows of assembly are required.
