Integrated Cable Connector Housing for Stress-Resistant Plugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors require separate manufacturing and assembly of two-piece housings, leading to complex assembly processes and potential disintegration due to overstressing of elastic elements when deviating from the correct plugging direction.
Innovation Solution
A cable connector with a metal housing that is integrally formed, featuring a plug end with elastic elements extending backward from a ring portion, allowing for simplified manufacturing and assembly, and preventing deformation by reversing the stress direction during plugging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cable connector uses a two-piece housing structure (first housing and second housing), then the manufacturing flexibility is improved, but the assembly process becomes complicated and the housing may separate after repeated plugging and unplugging
Solution Approach 1:
The patent merges the first housing and second housing into a single integrated housing structure. The housing includes a body portion and a cap portion that are formed as one piece, eliminating the need for separate assembly steps and preventing separation after repeated use. This resolves the contradiction by prioritizing structural integrity and assembly simplicity over manufacturing flexibility.
2Force
If the elastic elements extend forward from the ring portion toward the cable connector plug end, then the plugging force is improved, but the elastic elements are overstressed and deformed when the plugging direction deviates
Solution Approach 1:
The patent inverts the extending direction of the elastic elements. Instead of extending forward from the ring portion toward the plug end, the elastic elements extend backward from the ring portion toward the sleeve end. This inversion changes the stress distribution so that during normal plugging, the force is applied through the body portion rather than directly overstressing the elastic elements, thereby improving their durability while maintaining plugging functionality.
3Volume of moving object
If the distal end of each elastic element is close to the ring portion, then the elastic element structure is compact, but the distal end directly bears the stress of deviated cable connector during plugging
Solution Approach 1:
The patent changes the spatial arrangement by having the elastic elements extend backward from the ring portion rather than forward. This dimensional repositioning moves the distal ends of the elastic elements away from the high-stress plugging region, allowing them to maintain a compact structure while avoiding direct bearing of plugging stress, thus resolving the contradiction between compactness and stress resistance.

AI summary
A cable connector includes a metal housing, an insulator, and a cable. The metal housing includes a sleeve end, a main body, and a plug end integrally formed from rear to front. The plug end includes an end body having a plurality of holes formed therethrough, a ring portion extending forward from the end body, and a plurality of elastic elements extending backward from the ring portion. The cable is accommodated in the metal housing and fixed to the insulator. Therefore, by the metal housing integrally formed, the manufacturing steps and the assembly steps of the cable connector are simplified. Furthermore, by the design that each elastic element extends backward from the ring portion, the deformation of each elastic element due to the excessive stress during plugging is avoided.
