Heavy Duty Connectors - Housings, Hoods, Bases

Heavy duty connectors are used in a variety of applications, often in hazardous, high voltage environments. Examples of these applications include communications systems and industrial machinery. The 1678127 heavy duty connector housing, hood, and base are a specific type of connector manufactured by Amphenol Industrial Products Group (AIPG).

1678127 Connector Overview

The 1678127 series is designed for harsh environments such as road and off-road vehicles, mobile radio equipment, and control systems. It offers a rugged design, superior performance, low leakage current, and cost-effective assembly. This fixture contains four separate parts: the housing, the hood, the rear base shell, and the snap-in base.

Housing

The housing is the primary component of this connector and is the structural foundation of the system. It is molded from a high-impact, UL 94V0 thermoplastic and is designed to allow easy field acceptance and installation. The housing is shaped to provide a sealed interface between the hood and base shells, ensuring a high level of environmental protection and insulating against electric shock.

Hood

The hood is the second part of the 1678127 series connector. It is designed to provide extra protection from splashes, rain, and other environmental hazards. The hood also has shielding features which reduce the chance of electrical interference and provide additional insulation. It is made from a lightweight ABS plastic and is available in single-part or split-module configurations.

Base

The rear base shell is a strong and durable aluminum alloy shell. It provides excellent shielding and is also equipped with a number of strain relief features. The snap-in base is used to secure the electrical contact, cable, and other components of the connector. It is made from a rugged UL94V-0 thermoplastic and has excellent sealing capabilities.

Assembly

Assembly of the 1678127 series heavy duty connector is designed to be easy and cost-effective. The housing, hood, and base shells are connected together and secured with screws. The snap-in base is then connected to the housing with a key-lock mechanism. Once assembled, the 1678127 series connector provides superior environmental protection, as well as excellent electrical conductivity and resistance to shock and vibration.

Application Field and Working Principle

The 1678127 series heavy duty connector is designed for use in a variety of demanding applications. It is suitable for use in harsh environments such as off-road vehicles, mobile radio equipment, and control systems. The series provides superior performance, low leakage current, and excellent insulation protection to ensure reliable operations even in challenging conditions. The series is also easy to install and cost-effective. The working principle of the 1678127 series connector consists of the housing, hood, and base shells being connected together and secured with screws, while the snap-in base connects the electrical contact, cable, and other components of the connector. Once assembled, the connector provides superior environmental protection, electrical conductivity, and resistance to shock and vibration.
