Understanding 141A4810-56: A Comprehensive Guide to Industrial and Aerospace Connector Components

-

 In the world of industrial and aerospace parts, precise component identification and description play a vital role in procurement, maintenance, and compliance. Among such identifiers lies 141a4810-56, a part number that has emerged in supply chains, catalogs, and technical references. In this article, we explore what this designation represents, how it connects to broader categories like backshell electrical connectors and electrical connector systems, and why understanding related components is crucial for engineers, procurement specialists, and maintenance teams.

What Is 141A4810-56? An Introduction to Part Numbering

Part numbers like 141a4810-56 are used extensively in aerospace, aviation, and industrial engineering to identify specific component assemblies within complex systems. These structured identifiers often follow internal or supplier coding rules that encode manufacturer, part family, configuration, and revision details.

In some public inventory and distribution references, 141a4810-56 appears linked with airframe components, notably sliding windshield assemblies or window assembly parts used on commercial aircraft models such as those from Boeing. Multiple supplier and parts catalog listings identify entries similar to this part number in contexts associated with aircraft structural and cockpit components.

However, unlike standardized stock numbers such as NSN (National Stock Number) used for parts like backshell electrical connectors within connector families, 141a4810-56 is not easily found in major public NSN electrical component catalogs. Its presence is more common in aircraft physical inventory and OEM distribution records tied to mechanical assemblies.

This distinction underscores an important topic in parts management: a part number may represent a mechanical or structural assembly rather than an electrical connector sub-component, even though it may be used in tandem with electrical systems during integration or installation.

What Are Electrical Connectors and Backshell Electrical Connectors?

To better frame the universe in which parts like 141a4810-56 may intersect particularly in an aerospace context  it is essential to understand foundational components such as electrical connectors and backshell electrical connectors.

Electrical Connectors: The Core of Circuit Interfacing

An electrical connector is a precision device engineered to join electrical conductors, enabling current or signal flow between multiple parts of an electrical circuit or disparate circuits altogether. These connectors may be temporary (plug-and-socket), permanent, or specialized for specific signal or power requirements. They are characterized by parameters like pin count, contact type, material, and environmental resistance.

In professional industrial and aerospace applications, connector systems must deliver:

  • Mechanical Durability — Withstanding vibration, shock, and thermal stress.

  • Electrical Performance — Maintaining stable continuity, insulation, and low resistance.

  • Environmental Protection — Guarding against moisture, dust, EMI (Electromagnetic Interference), and RFI (Radio Frequency Interference).

Quality standards and military specifications such as MIL-DTL-5015 and other MIL-SPEC families govern acceptable performance levels for robust connectors used in demanding environments.

Backshell Electrical Connectors: Shielding and Strain Relief

A backshell electrical connector refers to a connector accessory that surrounds and reinforces the rear portion of a cable-to-connector assembly. Backshells serve several critical functions:

  • Strain Relief: Preventing stress on wire terminations.

  • Environmental Sealing: Protecting splices and cable jackets from contaminants.

  • EMI/RFI Mitigation: Reducing interference that could disrupt signal integrity.

Backshell products are often cataloged under dedicated part types in NSN inventories. For example, catalogs list dozens of backshell electrical connector variants distinguished by thread size, style (straight, right angle), plating, and mounting characteristics.

Some notable examples include parts like 10-035952-141 and 10-130380-141, which are recognized backshell electrical connectors from aerospace brands such as Amphenol Corporation.

How 141A4810-56 Fits Into the Broader Aerospace Parts Landscape

Although 141a4810-56 does not map directly to a standard electrical connector or backshell NSN category, its placement in aircraft component inventories suggests several takeaways:

Identifier Use Across Multiple Domains

The same base number often with revision or suffix descriptors may be applied to vastly different component types. For instance:

  • 141a4810-XX families are found in cockpit windshield assemblies based on Boeing aircraft documentation.

  • Other numeric series within the same pattern may belong to electrical control modules or mechanical interfaces.

This highlights a key point: part numbering conventions vary widely between mechanical, structural, and electrical systems, and part number similarity does not necessarily imply functional similarity.

Integration: Structural and Electrical Systems

In aerospace platforms, assemblies such as cockpit windows, airframe components, and electrical systems frequently integrate with one another mechanically and electronically. Cables and electrical assemblies may pass through structural apertures, necessitating connectors and backshells to protect and terminate them properly.

Experienced procurement and engineering teams, therefore, must carefully correlate part numbers against detailed BOMs (Bills of Materials) or CAD models to ensure the correct component type whether structural, electrical, or accessory is ordered, installed, and compliant with required specifications.

Best Practices for Procurement and Components Management

Whether your role involves sourcing, engineering design, or field maintenance, these practices help ensure accuracy and reliability:

Cross-Reference Part Numbers

Maintain authoritative cross-reference tables between OEM part numbers (like 141a4810-56), NSNs, and supplier equivalents. This eliminates mistakes where a part number could refer to unrelated systems.

Consult Industry Standards

Use internationally recognized electrical and mechanical standards including MIL-SPEC, IEEE connector standards, and aerospace manufacturer requirements to validate part performance, tolerances, and interchangeability.

Use Accredited Distribution Channels

Trusted distribution partners and accredited suppliers (e.g., AS9120B, ISO 9001:2015 accredited) help guarantee traceability and compliance of parts such as backshell electrical connectors, and reduce risk of counterfeit or non-compliant components entering critical systems.

Conclusion

141a4810-56 serves as an excellent example of how part numbers play a pivotal role in part identification, but also how they must be interpreted in context. While this particular identifier is linked with sliding windshield and structural assemblies in aerospace catalogs, related terminology  such as backshell electrical connector and electrical connectors  represents core elements of aerospace and industrial electrical systems. Understanding both the naming conventions and the functional categories behind these parts is essential for accurate procurement, maintenance, compliance, and system integrity.
