Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board): QMS-104-05.75-L-D-A

Rectangular connectors can be used in a variety of applications, from simple wire-to-board connections to complicated multi-directional devices. They are versatile, reliable, and have varying power requirements. The QMS-104-05.75-L-D-A is a particular type of rectangular connector, designed for edge-type, mezzanine applications.

Application Field

The QMS-104-05.75-L-D-A is designed for use in edge-type, mezzanine applications. This connector is typically used in data-intensive applications, consumer electronics, and medical devices. The connector is also used in industrial applications such as robots or machine vision systems.

Construction

The QMS-104-05.75-L-D-A connector uses a modular construction. The PCB connector consists of two parts: the pitch, which forms the base of the connector, and the conductors, or pins/sockets. The pitch of the connector can vary from 4.75mm to 95mm, allowing for a variety of configurations to be used. The conductors can also vary in pitch, from 0.25mm to 1.27mm. This gives the connector a high level of flexibility when being used in a range of applications.

Contact Termination

The QMS-104-05.75-L-D-A utilizes various types of metal contacts for termination. These contacts are designed to provide a secure connection to both sides of the connector. The primary contact termination method for this connector is press-fit, which is a combination of surface mount, through-hole, and screw-terminal. Additional types of contact termination such as crimping or soldering can also be used. The contact termination method used will depend on the application and the environment in which the connector is being used.

Environmental Performance

The QMS-104-05.75-L-D-A is designed to be used in harsh environments, where it must endure temperature extremes, weather/moisture, and vibration/shock. The metal contacts used on this connector are designed to provide superior performance in extreme environments. The press-fit components provide increased mechanical strength and low contact resistance, while the crimping contacts provide reliable performance in extreme temperatures and harsh vibration. Additionally, this connector meets the RoHS environmental protection and RoHS2 requirements for hazardous materials.

Working Principle

The QMS-104-05.75-L-D-A works on the principle of providing mechanical and electrical connection between two boards. This is typically done by using a press-fit method, which involves inserting the connector’s contacts into holes in the board. When the force is applied, the contacts are securely held in place. This provides a reliable electrical connection between the two boards. The press-fit method is also advantageous because it simplifies manufacturing processes and reduces assembly costs.Overall, the QMS-104-05.75-L-D-A is a versatile and reliable rectangular connector designed for edge-type, mezzanine applications. It provides a secure, mechanical and electrical connection between two boards. Its modular construction allows for a variety of configurations, while its press-fit contact termination methods ensure reliable performance in extreme environments. This connector is ideal for data-intensive applications and other mission-critical operations.
