Connector Housing Concave Surface for Cylindrical Member Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector housings struggle to maintain an appropriate posture when fixed to a cylindrical member, such as a corrugated tube, due to the rigidity difference between the housing and the tube, leading to instability and difficulty in secure attachment.
Innovation Solution
The connector housing features a concave surface on its outer circumferential surface that curves in an arc shape, allowing it to be pressed against the cylindrical member in alignment with its extending direction, combined with ribs on the top wall to prevent tape miswinding, ensuring stable fixation and posture maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the connector housing is pressed against the outer circumferential surface of the cylindrical member, then the connector housing can be fixed to the cylindrical member, but the cylindrical member does not deform to follow the configuration of the connector housing due to rigidity difference, causing instability in posture
Solution Approach 1:
The connector housing incorporates a concave surface with an arc shape that curves inwards, matching the cylindrical shape of the cylindrical member. This curved surface allows the connector housing to conform to the cylindrical member's geometry, enabling stable fixation while maintaining proper posture alignment between the two components.
2Device complexity
If the connector housing is fixed to the cylindrical member without a concave surface, then the structure is simpler, but the connector housing cannot maintain appropriate posture when the cylindrical member's direction deviates
Solution Approach 1:
The concave surface with arc shape provides adaptability to posture variations by conforming to the cylindrical member's curvature, allowing the connector housing to maintain proper alignment even when the cylindrical member's direction deviates slightly, without requiring complex adjustment mechanisms.
3Reliability
If the connector housing is fixed to the cylindrical member, then the connection is secure, but it is difficult to fix the connector housing while keeping it in an appropriate posture
Solution Approach 1:
The concave surface automatically guides the connector housing into the correct posture relative to the cylindrical member during the fixation process. The curved geometry provides a self-aligning mechanism that simplifies installation while ensuring reliable connection, eliminating the need for precise manual positioning.

AI summary
A connector housing includes a cylindrical side wall. The cylindrical side wall includes a concave surface on one side of an outer circumferential surface of the cylindrical side wall in a first direction. The concave surface curves inwards into an arc shape and extends in a second direction, so that the concave surface is to be pressed against a cylindrical member with the second direction aligned with a direction in which the cylindrical member extends.
