Rectangular connectors are a popular type of electrical connectors available in either male or female housing. A common example is the SBH51-LPSE-D43-ST-BK, which is a header with male pins and is typically used in applications ranging from medical to general electronics. This article discusses the SBH51-LPSE-D43-ST-BK\'s application field and working principle.

Application Field

The SBH51-LPSE-D43-ST-BK is a header with 4 pins, and is ideal for applications dealing with low current requirements, such as power converters, digital circuitry, communications equipment, and computer systems. It offers excellent signal integrity for data and control transmissions due to its low crosstalk and reduced noise. It also offers excellent interconnection reliability when connected with a PCB board or other mating connector. Additionally, its durability and corrosion-resistance make it suitable for harsh industrial environments, such as marine and automotive applications.

Working Principle

The SBH51-LPSE-D43-ST-BK consists of aPCB board with four equally spaced holes, and a male pin connected to each of the four holes. The four male pins are connected to individual copper foil strips or metallized lines. These lines are surrounded by an insulation shield to provide protection from spills, shocks, and other environmental influences. When the SBH51-LPSE-D43-ST-BK is correctly inserted into the mating connector, the contact points of the pins should align with the contact points of the female connector. The pins should then make a strong mechanical connection, and an electrical connection—which enables power and data to flow between the two components.

The electrical connection between SBH51-LPSE-D43-ST-BK and the mating contact is facilitated by the contact pressure between the pins and the contact. This contact pressure is generated by two main forces: the cone force, which is generated by the force of the pins entering the contact; and the spring force, which is generated by the tension of the spring present in the mating part of the connector. Normally, the cone force is greater than the spring force so that it pushes the pins into the mating contacts more firmly.

In addition, the SBH51-LPSE-D43-ST-BK is designed with locking features, such as detents, so that the pins will be held securely in place when they are inserted into the mating connector. The detents along the flange of the male pin provide a lateral locking force that resists against any stress or shock that may be applied to the header. This feature ensures that the electrical connection between the two components is secure, and prevents any unnecessary interferences or disruptions.

When considering which type of rectangular connectors is best suited for an application, factors such as performance, durability, and price should be taken into consideration. The SBH51-LPSE-D43-ST-BK is an ideal choice for applications requiring highly reliable electrical connections, and is suitable for both low and high current requirements. It is a cost-effective, yet reliable solution for many types of electrical boards and applications.
