The QTH-020-07-H-D-DP-A is a type of rectangular connector arrays, edge type, mezzanine (board to board). It\'s a great plug-in connector with reliable contact function and helpful installation design. This kind of connector is widely used for the high density board-to-board interconnections. Understanding the QTH-020-07-H-D-DP-A\'s application field and working principle can help you make the most cost effective and reliable electronic interconnection design for your products.

QTH-020-07-H-D-DP-A has full range of pitch and pin count, 1.5mm and 7 pins. This kind of connector can provide a zero insertion force for reliable contact and high density connection. It comes with the nickel plated brass contact, which provides a great electrical and mechanical performance. There are both surface mount and right angle version of QTH-020-07-H-D-DP-A, which together provide flexibilities for board-to-board connections.

QTH-020-07-H-D-DP-A is mainly used for high-density board-to-board connections, computer or digital electronic technical fields, such as servers, laptop, mobile phones, and other portable electronic products. This connector can effectively reduce the whole connection space, which helps save production costs. Thus, it is ideal for products with high-density miniaturization requirements.

QTH-020-07-H-D-DP-A\'s working principle is based on the structure of the contact system. It adopts a two-row contact, which consists of a low contact system and an upper contact system in all the pins. The bottom contact system consists of plunger contact and wafer spring, which provides a zero insertion force connection. While inserting the male connector, the plunger contact and the wafer spring contact will be compressed and the resilient fork will contact the pin terminal of male connector, thus securely electrically connect male and female connectors. The high contact system consists of female contact, which is clamped on the circuit board. The male contact has a bent tail and a soldering collet. When the male connector is inserted correctly, the bent tail of the female contact will press the male contact tightly and the soldering collet is soldered to the printed circuit board. This provides the second contact between the female and male connector and ensures the connection.

In conclusion, QTH-020-07-H-D-DP-A is a high-performance rectangular connector array, edge type, mezzanine (board to board), it has high population density and high insertion forces. It is widely used for high-density board-to-board connections in computer or digital electronic technical fields. Its working principle is based on the structure of the contact system, which uses a low-contact and high-contact system to securely electrically connect the male and female connectors. The zero insertion force of this connector makes it an ideal choice for applications with miniaturization requirements.
