Rectangular connectors comprise a class of electrical connectors featuring flat, usually rectangular-shaped contact areas. Two or more pieces of these connectors come together in order to connect two or more electrical circuits. Depending on its design, a rectangular connector can provide various levels of contact and insulation protection. Rectangular connectors come in various types, including headers, male pins, and others. 770858-2 is an example of the latter. This article will explore the application field and working principle of 770858-2.

770858-2, also known as the RB-145 series of rectangular connectors, is a 2-pin type connector designed for use in general-purpose applications. It features a 5.9mm centerline spacing and a 5.9mm diameter barrel connector plug. This connector can accommodate wire-to-board connections with a maximum rated current of 18..1A, a maximum voltage of 250VAC, and a maximum ambient temperature of 85°C. Additionally, its two contact points are designed to make low-resistance contact for reliable connections.

The main application field of 770858-2 is in the production of electronic assemblies, such as DIN-rail mounted meters and controllers. This connector is a suitable choice for connecting electric modules that require a reliable and robust connection. Its two contact points also make it suitable for applications that require the connection of two electric signals, such as the input and output of a signal or power converter.

The working principle of 770858-2 is simple and relies on direct contact between the two contact points. When the mating plug is inserted into the barrel of the connector, the contact points are forced into direct contact with each other. This, in turn, creates an electrical connection between the two circuits. Additionally, depending on the design of the mating plug, the connector can be designed to provide either single-layer or multi-layer insulation protection.

In conclusion, 770858-2 is an example of a rectangular connector designed for general-purpose use. It is most commonly used in the production of electronic assemblies and is suitable for applications that require a reliable and robust connection. It works on the principle of direct contact between the two contact points and is capable of providing various levels of insulation protection.
