Cable Connector Cover Structure for Screwless Stable Cable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector devices face challenges with cumbersome cable fixation methods, leading to potential positional misalignment and loosening due to external forces, which reduces productivity and increases the likelihood of wobbling and floating of the inner housing.
Innovation Solution
A cable connector device featuring a cover member with a first and second cover part, including a periphery wall, raised portions, and an elastic movable piece, which stabilizes the cable connector by sandwiching the cable and engaging with a counterpart connector, eliminating the need for screwing and reducing wobbling through precise positioning and engagement mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable clamp is screwed onto a fixation base to fix the cable, then the cable fixation is achieved, but the assembly process becomes cumbersome and productivity decreases
Solution Approach 1:
The patent replaces the screwing mechanical system with a snap-fit engagement system. The inner housing has engaging protrusions that fit into engaging recesses on the base case, eliminating the need for screws and cable clamps. This substitution maintains fixation reliability while dramatically improving assembly speed and productivity.
Solution Approach 2:
The inner housing is designed to be self-fixing through its engaging protrusions that automatically engage with the base case upon insertion. The elastic deformation of the inner housing material enables self-locking without requiring external fastening operations, making the assembly process self-service and highly efficient.
2Productivity
If the inner housing is elastically mounted on the base case with engaging protrusions, then assembly is simplified, but the inner housing may wobble or float before cable fixation
Solution Approach 1:
The patent implements preliminary positioning features on the base case, including positioning protrusions and positioning recesses, that guide and stabilize the inner housing before final engagement. This preliminary action prevents wobbling and floating during the assembly process, ensuring positional stability before the elastic snap-fit engagement completes the mounting.
Solution Approach 2:
The patent applies different local qualities to different parts of the mounting structure. The base case has rigid positioning features for stability, while the inner housing has elastic properties for secure engagement. This combination of rigid positioning and elastic fixation at different locations resolves the contradiction between assembly speed and positional stability.
3Manufacturing precision
If multiple components are assembled with precise positioning, then engagement accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple positioning functions into integrated features. The positioning protrusions and recesses are formed as integral parts of the base case and inner housing, combining positioning, guiding, and engagement functions into unified structures. This merging achieves precise engagement positioning without proportionally increasing device complexity.

Implementation Method 1
An elastic movable piece that manipulates a movable engaging portion that engages with a predetermined portion of the counterpart connector
Implementation Method 2
part of the periphery wall where the elastic movable piece to be positioned when the main body of the cable connector is mounted on the mount surface is formed as a cantilever-like elastic piece that manipulates the elastic movable piece

AI summary
A cover member includes a first cover part and a second cover part. The first cover part includes: a mount surface on which a main body of a cable connector is mounted; a periphery wall which is provided to lie substantially along an outer edge of the main body of the cable connector mounted on the mount surface and which is raised from the mount surface toward a side on which the first cover part is combined with the second cover part; a cable outlet and a connection port; an engaging portion that engages with a predetermined portion of the second cover part; and a pair of raised portions raised from the mount surface toward the side on which the first cover part is combined with the second cover part, the pair of raised portions being provided at positions which sandwich a cable extending out from the main body of the cable connector mounted on the mount surface and which are at or near the cable outlet.
