ESQ-105-23-T-D Application Field and Working Principle

ESQ (European Series Quantity) rectangular connectors are a type of non-standard, multi-pin rectangular electrical connector widely used in commercial electronic equipment. ESQ-105-23-T-D are hybrid headers and receptacles, having both Male and Female pin configurations, that are designed to interconnect two or more cables or printed circuit boards. The number 105 (105 pins per connector) indicates the number of pins in each connector while 23 indicates the number of positions and T denotes the type of terminals/contacts used – in this case, T type (Table 2).

The circuit diagrams in Figures 1 and 2 show the two basic female and male configurations that the ESQ-105-23-T-D connectors feature. Figure 1 shows the typical female contact configuration, in which 23 pins with polarizing pins are mounted on a milled aluminum housing so that the insertion force is evenly distributed throughout. Figure 2 shows the male contact configuration, in which 23 pins are soldered onto a stiffener. The polarization of the pins ensures that the connectors can be plugged in no more than one way. This prevents wrong connections and ensures safety during use.

The ESQ-105-23-T-D header and receptacle connectors are most commonly found in power supplies, telecommunications, aerospace, and medical equipment. They are frequently used in systems that are physically exposed to the environment, such as those used in industrial settings, since they can withstand extreme temperatures, moisture, dust, shock, and vibration.

The ESQ-105-23-T-D connectors have several unique features that make them a preferable choice over other connectors. Firstly, they have open-ended contact points which allows for easier cleaning and inspection. Secondly, the body of the connector and its contacts are designed to provide a high degree of durability and resist vibration. This makes them less prone to premature failure, even after continuous and extreme use. Finally, the connector assembly is designed to self-align, which helps maintain good electrical continuity.

The connector assembly works by making an electrical connection between two contacts that have been brought into contact with each other. This is done by using a contact system, such as a conductive metal spring, to ensure that when the two ends of the connector are brought into contact, the spring forces them together and creates an electrical connection. In addition, the contact system also ensures that the contacts maintain good electrical continuity over time and are not exposed to corrosion.

The ESQ-105-23-T-D rectangular connector is the ideal solution for complex applications that require a reliable, low-cost, and easy to install connector. It offers superior performance in a wide range of applications, providing users with a reliable and efficient connection for their devices.
