The QTE-040-04-F-D-A series of rectangular connectors are part of the array, edge type, mezzanine (board to board) category of connectors. These connectors are designed for a variety of applications, ranging from communications and distributed data processing systems to computer system boards.

The connectors offer space saving limitations and fast, easy installation in highly populated applications. Features include a four sided hinged connector with a versatile tongue and grove locking mechanism which allows for vertical and horizontal locking. The connector has two rows of 16 contacts, arranged in a matrix of 4 x 8, in two levels. The contacts are dual crimped, tin plated and polarization for secure mating.

The QTE-040-04-F-D-A connectors offer superior shock and vibration resistance and are highly reliable and durable. When properly mated, the connectors are watertight, providing complete protection against EMC/EMI. The design also allows for more connector contacts to be integrated within a smaller profile due to its high density fine pitch design.

The application field and working principle of the QTE-040-04-F-D-A series of connectors is based on the principles of power and signal transmission through a hinged array interface. The connectors feature signal contacts that are gold plated which provide superior electrical performance and are suitable for both digital and analog applications. The power contacts are copper alloy which provide maximum power carrying capacity. The dual row design is also advantageous as it allows the transfer of four different signals while accommodating only two mounting levels.

The working principle of the connectors involves mulitple mating components. The two mating halves consist of an insulator housing and a terminal strip. The insulator housing is composed of dielectric material and typically consists of a mated set of hinged matrixed terminals. One half of the terminal strip is then inserted into the corresponding insulator housing. The terminals are sprung to ensure a tight grip of the contacts and a secure mated connection. The contacts inside the housing act as a backplane and a connection terminal between the various circuits. Additionally, the flexible locking mechanism allows for fine tuning stability and ensures secure mating.

The QTE-040-04-F-D-A series of connectors are widely used in a variety of applications that require reliable power and signal transmission. They represent a cost-effective alternative to traditional wiring and are designed to reduce cabling and installation time significantly. The high degree of durability and reliability as well as the superior electrical performance of the connectors ensure that users will achieve long-term reliability and peace of mind. With their space saving design and quick installation, the QTE-040-04-F-D-A series of connectors are ideal for use in a variety of distributed data processing and communications applications.
