Cable Connector Multi-Stage Engagement Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors face usability issues due to instability and complexity in mounting cable holders, particularly at temporary fixing positions, which becomes more pronounced with the reduction in apparatus size.
Innovation Solution
A cable connector design featuring a housing with three engagement portions on each side, allowing the cable holder to be positioned at two engagement states: a first position for temporary fastening and a second position for complete latching, using engagement portions on the cable holder and housing to stabilize the cable holder during mounting and usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cable holder is mounted at a temporary fixing position during assembly, then the mounting process becomes simpler and more efficient, but the cable holder becomes unstable and may come off during use
Solution Approach 1:
The engagement structure is divided into multiple engagement portions (first, second, and third engagement portions) arranged in the lead-out direction. This segmentation allows the cable holder to be mounted in stages - first to a temporary fixing position using the first engagement portion, then to a final stable position using the second and third engagement portions, thereby resolving the contradiction between easy mounting and stable fixation
Solution Approach 2:
The cable holder is preliminarily fixed at a temporary fixing position during the mounting process to simplify assembly operations. This preliminary action enables easy initial mounting while subsequent actions (engaging the second and third engagement portions) stabilize the cable holder to prevent it from coming off during use
2Reliability
If the cable holder is designed with multiple engagement portions for stable mounting, then the cable holder stability improves, but the device complexity increases
Solution Approach 1:
Multiple engagement portions (first, second, and third engagement portions) are combined on the cable holder and housing to work together as an integrated engagement system. This merging provides enhanced stability through multiple engagement points while maintaining relatively simple individual structures, resolving the contradiction between stability and complexity
3Volume of moving object
If the apparatus size is reduced, then the portability and compactness improve, but the mounting stability of the cable holder deteriorates
Solution Approach 1:
The engagement portions are arranged in the lead-out direction (a specific dimension) rather than solely in the mounting direction. This dimensional arrangement allows multiple engagement portions to be distributed along the cable lead-out path, providing stable mounting even in compact apparatus with reduced overall size

AI summary
Provided is a cable connector which includes: a housing; and a cable holder capable of holding one end side of the cable. The cable holder includes at least three first to third engagement portions on each of opposing outer side surfaces, in a direction along a lead-out direction where the cable held on the one end side by the cable holder is led out from the cable holder, the first engagement portion is placed on a side far from the cable lead-out side of the cable holder, the second engagement portion is placed on a side near the lead-out side, and the third engagement portion is placed between the first engagement portion and the second engagement portion, the housing includes at least three first to third corresponding engagement portions capable of engaging respectively with the first to third engagement portions, on each of opposing inner side surfaces, it is configured in such a manner that, upon the first to third engagement portions engaging with the first to third corresponding engagement portions, respectively, the cable holder is capable of being placed at least at a first engagement position and a second engagement position with respect to the housing, at the first engagement position, the first and second engagement portions are in engagement with the first and second corresponding engagement portions, respectively, while the third engagement portion has not yet engaged with the third corresponding engagement portion, and at the second engagement position, all the first to third engagement portions are in engagement with the first to third corresponding engagement portions, respectively.
