Cable Assembly Housing Closure Without Casting Weld Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for holding cable harnesses or similar elongated elements are prone to breakage due to weld lines formed during casting, especially under high operating forces and low temperatures, leading to insecure closures.
Innovation Solution
The device features a receptacle design with a web connected to the casing at one end and two side segments extending in different directions, eliminating the formation of weld lines by diverging material flows, and incorporates detent elements to ensure secure closure even under torsional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a ring-segment-shaped receptacle connected at both ends is used, then the closure structure is complete, but weld lines form during casting making it susceptible to breakage
Solution Approach 1:
The receptacle is segmented into a web portion and two side segments. The web is connected to the housing at one end only, while the side segments extend from the web in different directions. This segmentation prevents the formation of a continuous ring structure that would require material flow from both ends, thereby eliminating weld lines and improving strength.
Solution Approach 2:
Instead of connecting the receptacle at both ends to the housing (conventional design), the invention inverts the connection approach by connecting only at one end. The web is attached to the housing at its first end, while the second end remains open, allowing material flow from a single direction and preventing weld line formation.
2Ease of manufacture
If conventional casting methods are used with ring-segment receptacles, then manufacturing is simple, but the casting material forms weld lines that reduce reliability
Solution Approach 1:
The receptacle geometry is segmented into distinct portions (web and side segments) that guide material flow in a controlled manner. This segmentation allows the casting process to remain simple while eliminating the harmful weld line effect by ensuring material flows from only one end through the web to the side segments.

AI summary
The invention relates to a device (1) for accommodating a cable assembly. The device comprises: a casing (2) having a receiving portion (3) with a connecting piece (4), which is connected to the casing (2) by its first end and extends away from the casing (2) towards the second end, two side sections (5a, 5b) which are each connected at one end to the connecting piece (4), extend away from the connecting piece (4) towards the other end and extend in different directions; and a cover (6) having an insertion part (7) for inserting into the receiving portion (3), the insertion part (7) having two sub-sections (8a, 8b) and each sub-section having an engaging element (9a, 9b). The device (1) is designed in such a way that the insertion part (7) can be pushed into the receiving portion (3), wherein the connecting piece (4) is then positioned between the sub-sections (8a, 8b). In addition, the engaging elements (9a, 9b) prevent the insertion part (7) from sliding out if the insertion part is pushed in far enough that each engaging element (9a, 9b) has passed beyond a side section (5a, 5b),
