Cable Connector Cantilevered Arm Positioning Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors with separate cable holders face issues with maintaining the position of fixing portions relative to the contact support portion, especially when cables are accidentally pulled, leading to potential displacement during mounting and after.
Innovation Solution
A cable connector design featuring cantilevered arm portions on the cable holders that extend in the mounting direction, allowing them to face and align with the housing along the cable's lead-out direction, facilitating stable positioning and locking mechanisms with protruding portions for temporary and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable holders are mounted on the contact support portion, then the cable can be held and organized, but the positions of the fixing portions may be displaced during mounting or after mounting when cables are accidentally pulled
Solution Approach 1:
The patent applies preliminary action by providing guide portions on the housing that engage with the cable holders before the final locking operation. These guide portions pre-position the cable holders in the correct location and orientation, ensuring accurate positioning is established prior to mounting. This preliminary guiding action prevents displacement during the subsequent locking process and maintains position stability even when cables are accidentally pulled after mounting.
2Ease of manufacture
If extending portions are assembled to determine positions of fixing portions, then assembly is simplified, but the positions may still be displaced as the extending portions do not provide sufficient positional constraint
Solution Approach 1:
The patent introduces guide portions as intermediary elements between the housing and cable holders. These guide portions act as mediators that provide both positioning guidance and mechanical constraint. The guide portions engage with corresponding features on the cable holders to maintain precise positional relationships during assembly and operation, thereby achieving both assembly simplicity and position accuracy simultaneously.

AI summary
For example, the provision of a cable connector where a cable holder can maintain the position of a member where the cable holder is mounted, before and after the mounting. The cable connector includes a housing and paired cable holders. One end of a cable can be mounted in each of the paired cable holders. Each of the paired cable holders includes a cantilevered arm portion extending in a mounting direction of the cable holder on the housing. At least part of the arm portion can come face to face with part of the housing in a direction along a lead-out direction of the cable from the cable holder, at the time and after the mounting of the cable holder on the housing.
