Heavy Duty connectors are essential components within the electrical and electronics industry. They are a specific type of electrical connector designed to connect several wires within a closed circuit system for high wattage or long-term voltage power applications. The industry categorized these connectors into different series of insertion modules.

The 1855050 series of inserts and modules are some of the most popular in the industry, due to their ability to interconnect power and signal for both high current and signal charge applications. Developed by TE Connectivity, this series also comes with a range of accessories which allow it to connect with more complicated systems which require greater load currents.

Application Field

The 1855050 series was initially designed as a range of inserts and modules for automotive electrical systems, allowing them to interconnect and control the vast variety of components within the system such as battery power and motor control circuitries. Subsequently, their application has evolved into most other areas of electrical engineering, with increased power carrying capacity and level of reliability.

The inserts and modules of this series are most commonly used for applications requiring mid- to high-voltage electrical power distribution between the source and the user. This can include applications such as industrial power distribution, machine tool components, railway electrical equipment, heavy machinery, electric vehicles, power grid networks, and electric installations in a multitude of industries. In addition, electrical connections between safety circuits, such as ground-fault protection and shock protection, frequently calls for the use of the 1855050 series.

Working Principle

The 1855050 series of heavy duty connectors combines user safety, efficiency and reliability into one device. They are constructed with a unique grounding mechanism which ensures that the power supply remains independent from the signal side in order to avoid interference. Each Insert module contains two metal contacts (male and female) which are coupled with the appropriate enclosure to ensure that they remain in place and protected from external forces.

The key feature of the series is its electrical power interconnect mechanism, which consists of copper alloy contact arms that are specially designed to maximize contact pressure, allowing for an efficient and reliable connection. In addition, the contact arms contain an internal spring that further ensures continuity and prevents arcing between contacts.

The inserts and modules of the 1855050 range also feature dual securing systems with an added benefit of being flame retardant. This allows them to remain durable even in intense and hazardous environments, ensuring the safe transfer of power and signal between the terminals. They are also available in different sizes and wattage limits, enabling users to find a device suitable for whatever their application requirements may be.
