Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable feedthroughs lack flexibility in adapting to different application situations and often fail to provide a secure mounting on separating elements, especially in environments with vibrations or impacts.
Innovation Solution
A cable feedthrough design featuring a feedthrough housing with a dividing component and sealing elements, secured by a screw-in and locking component, allowing for individual adaptation and secure mounting through a screw connection, with sealing elements made of elastic material for effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a cable feedthrough uses a simple grommet and guide part design, then the device complexity is reduced, but the adaptability to different application situations deteriorates
Solution Approach 1:
The cable feedthrough is divided into distinct functional modules: a feedthrough housing containing a dividing component with multiple receptacles, each receptacle holding a separate sealing element. This segmentation allows independent configuration of each cable passage while maintaining a unified mounting structure, enabling adaptation to different application scenarios without redesigning the entire device.
Solution Approach 2:
The feedthrough housing with multiple receptacles and sealing elements serves multiple functions simultaneously: it provides sealed passages for multiple cables, offers a standardized mounting interface via the distal screw-thread portion, and allows flexible configuration through the dividing component. This multi-functionality enables the same basic structure to adapt to various application situations.
2Ease of manufacture
If a cable feedthrough uses a simple mounting design without screw connection, then the ease of manufacture is improved, but the reliability of mounting under vibrations or impacts deteriorates
Solution Approach 1:
The distal screw-thread portion is pre-integrated into the feedthrough housing during manufacturing, preparing the mounting interface in advance. This preliminary action allows the feedthrough to be securely fastened to the separating element using a standardized screw connection, ensuring reliable mounting under vibrations or impacts while maintaining ease of manufacture through the pre-prepared threading.
3Reliability
If sealing elements are made of elastic material, then the sealing effect is improved, but the device complexity increases due to additional material requirements
Solution Approach 1:
The sealing elements are made of elastic material, changing the material parameter from rigid to flexible. This parameter change enables the sealing elements to deform and conform to the cable surfaces and receptacle geometries, creating effective seals. The elastic material compensates for manufacturing tolerances and cable variations, maintaining reliable sealing without requiring complex adjustment mechanisms.

Function Achieved in This Case
The design enables flexible adaptation to various applications and ensures secure mounting, even in conditions with vibrations or impacts, by securing the dividing component and sealing elements, while maintaining a sealing effect around the cables.
Implementation Method 1
a seal arranged on the feedthrough housing, on which seal the sealing elements, when arranged in the receptacle, sealingly come to rest against

AI summary
The invention relates to a cable feedthrough for feeding cables through a separating element, comprising: a feedthrough housing (2), which has a housing interior (7), which is delimited by a lateral housing wall (8) and a housing bottom (9) having a bottom opening (10) for feeding a plurality of cables through; a dividing component (3), which is arranged in the housing interior (7) opposite the housing bottom (9) and provides receptacles (15); and sealing elements (4), which are each arranged in one of the receptacles (15) and which each have a cable passage (19), which is designed to sealingly receive a cable. In one embodiment, a screw-in and locking component (5) is provided, which has a proximal screw-thread portion (22) and a distal screw-thread portion (23) with respect to the feedthrough housing (2), the proximal screw-thread portion (22) being screwed into an internal screw-thread portion (11) of the feedthrough housing (2) in such a way that the dividing component (3) and the sealing elements (4) are thus secured in the housing interior (7) by means of the screw-in and locking component (5), and the distal screw-thread portion (23) being designed to form, with a threaded connection partner, a screw connection for mounting the feedthrough housing (2) in the region of an opening (28) in a separating element (1). The invention further relates to an assembly.
