Connector Housing With Cable-Restricted Claws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for high-voltage and high-current electric cables require multiple components and complex assembly processes, including bolt tightening, which increases production complexity and component count.
Innovation Solution
A connector design featuring a tube-like metal cover and a flexible resin housing with engageable claws that use the electric cable to restrict position, eliminating the need for additional bolts and simplifying assembly by using the cable to secure the cover and housing in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple metal components (shell and shield stopper) are used to form the cover, then the connector achieves water-proof and oil-proof protection, but the number of components increases
Solution Approach 1:
The patent combines the shell and shield stopper into a single integrated cover member that provides both shielding and protective functions. The cover member is formed as one piece with continuous metal material, eliminating the need for separate components while maintaining water-proof and oil-proof protection capabilities.
2Stability of the object's composition
If bolts are used to tighten the shell and shield stopper, then the cover structure is secured, but the production process becomes complicated
Solution Approach 1:
The cover member is formed as a single integrated component through molding or forming processes, eliminating the need for assembly operations involving bolts. The unified structure achieves structural stability without requiring fastening operations, thereby simplifying the production process.
Solution Approach 2:
The patent replaces the mechanical fastening system (bolts and bolt holes) with a monolithic structure formed by molding or forming processes. This substitution eliminates the need for mechanical assembly and tightening operations, reducing production complexity while maintaining structural integrity.
3Quantity of substance
If a single-component tube-like cover is used, then the number of components is reduced, but the assembly certainty may be compromised
Solution Approach 1:
The single-component cover member is designed to self-align and self-secure with the housing through integrated features such as engagement protrusions and recesses. The cover member's own structure provides the necessary positioning and fixation capabilities without requiring additional components or complex assembly procedures.

AI summary
A connector 1 includes a metal terminal part 12 on which conductive wires 22 exposed outside at an end of an electric cable 2 are pressure-contacted; a housing 10 for accommodating the end of the electric cable 2 and the metal terminal part 12; and a tube-like metal cover 11 for covering the housing 10 and fixing the housing 10 to an electric device M. The housing 10 has an electric cable insertion hole 10e through which the electric cable 2 is insertable. The housing 10 includes an engageable claw 10d as position restriction means for restricting relative positions of the housing 10 and the metal cover 11. The engageable claw 10d is restricted, by the electric cable 2 inserted into the electric cable insertion hole 10e, from being displaced.
