Rectangular Connectors - Headers, Receptacles, Female Sockets encompass a wide variety of interconnection products that can be used for electronic devices. While the specific components used in connector assemblies have changed over the years, the basic purpose of connecting two or more circuit elements has remained unchanged. This article will provide information on the 5-146138-3 application field and working principle.

The 5-146138-3 is a two-piece interconnection system consisting of a 3-position header and a corresponding receptacle. The header is designed to accept a mating 16 AWG signal lead for each position while the receptacle comes with corresponding polarized inner contact points to ensure that the inserted leads are securely anchored. The polarizing feature also serves to enable proper mating of the connector assembly.

The 5-146138-3 can primarily be used for joining and interconnecting printed circuit boards (PCBs) and chassis with electrical components. It is a popular choice for applications that have limited space, since its relatively small surface area provides a smaller, more compact fit onto the PCB or chassis. The 5-146138-3\'s two-piece connector design also assists in the simplification of cable assembly and reduces the installation labor cost.

The 5-146138-3 header and receptacle can be secured together either manually or with a crimping tool. To connect the header to the PCB, the user could use fasteners such as screws and washers mounted on the PCB. To secure the receptacle to the PCB, press-fit mount pins can be used to fit the receptacle into pre-defined holes in the PCB. The press-fit pins ensure a secure bond between the PCB and the header/receptacle connector assembly.

The working principle of the 5-146138-3 is relatively straightforward and involves a few basic steps. When the female plug is inserted into the header, the depression on its mating surface allows the receptacle\'s polarized inner contact points to be engaged. As the plug is inserted further, the corresponding polarized inner contact points are engaged onto the mating surface, thus ensuring a secure and reliable connection between the PCB and the two components. This connection is then securely held by a locking clip, which also ensures the assembly remains firmly in place.

The 5-146138-3 connector assembly provides a reliable connection between electrical components in a variety of industrial applications. This versatile assembly is suitable for use in a wide range of circuit board designs as well as for joining multiple chassis and printed circuit boards. With its two-piece design, fastening the two components is relatively easy and efficient, while the press-fit mount pins provide a secure attachment to the PCB. Thanks to its polarizing feature, the 5-146138-3 ensures that the correct connection is made on the first attempt. Taking all these advantages into consideration, it is easy to understand why the 5-146138-3 has become a widely-used two-piece connector system.
