The SHIELD-KON GSB 5219 SR INNENHÜLSE shield connection connector from Lapp is a two-part cable lug, specifically designed for processing shielded cables in the fields of telecommunications and railway applications. It serves as the inner sleeve in the shield connection connector system and is used together with an outer sleeve to create a secure and durable connection between the cable shield and the connection point. The inner sleeve is made of a hard, stable material that absorbs the crimping pressure and protects the internal conductors of the cable from mechanical damage. The silver-colored finish ensures good electrical conductivity and corrosion-resistant connections.

Applications
This product is intended for use in applications requiring reliable shield connections, particularly in telecommunications and railway sectors. It is suitable for shielded cables with a dielectric diameter between 1.1 mm and 9.4 mm, i.e., after removal of the outer shield. This range covers a wide variety of cable types used in industrial and infrastructure installations.

Features and Equipment in Detail
The inner sleeve features a stable, hard construction that absorbs pressure during crimping, thereby protecting the internal conductors of the cable from mechanical stress. The combination of a hard inner sleeve and a soft outer sleeve ensures optimal load distribution and prevents the conductors from being punctured or damaged. The silver-colored surface enhances electrical conductivity and the corrosion resistance of the connection.

Technology Explained Simply
The inner sleeve functions as the central component in the shield connection connector system. It is slid over the cable core after the shield has been removed and absorbs the pressure of the crimping process. This prevents the internal conductors from being damaged by the crimping force. This design ensures a durable and reliable shield connection, which is critical for signal integrity in sensitive applications such as telecommunications or railway systems.

Compatibility and Accessories
The shield connection connector is designed for processing shielded cables with a dielectric diameter of 1.1 to 9.4 mm. It is part of the SHIELD-KON system and is used together with a matching outer sleeve. The exact selection of the outer sleeve depends on the cable type and requirements for mechanical and electrical connection. The inner sleeve is not intended for direct use as a standalone component but must be combined with the outer sleeve to fulfill its intended function.

Installation and Mounting
Installation involves several steps: First, the outer shield of the cable is removed, exposing the dielectric core. The inner sleeve is then slid over the cable core and positioned. Subsequently, the outer sleeve is slid over the inner sleeve and crimped hexagonally using an appropriate crimping tool. The crimping process must follow the specified crimp geometry to ensure a secure and conductive connection. Precise crimping is crucial for the functionality and lifespan of the connection.

Operational Advantages
Using the inner sleeve in the SHIELD-KON system provides the advantage of a mechanically stable and electrically conductive connection that protects the internal conductors of the cable. The hexagonal crimping of the outer sleeve ensures even load distribution and prevents the inner sleeve from being punctured. This maintains signal integrity and ensures the connection is resistant to mechanical stress and environmental influences. The silver-colored surface supports corrosion resistance and electrical conductivity, which is particularly beneficial in demanding environments.
