Hook-Shaped Connector Shell Layout for Front Impact Wire Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector mounting structures face issues where impacts from the front can cause deformation or breakage of wires and reduce the workability of attaching and detaching connectors, especially in vehicles.
Innovation Solution
A connector mounting structure where the connector is detachably attached to a case with a hook-shaped connector shell that extends outward and bends downward, distributing impact loads and allowing the connector to be attached and detached without reducing workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is disposed on the front side of the case for easy attachment and detachment, then workability is improved, but the wire is vulnerable to deformation or breakage from front impacts
Solution Approach 1:
The patent introduces a bumper as an intermediary component positioned between the case and the connector. The bumper absorbs front impacts before they reach the connector and wire, acting as a mediator that protects the wire from harmful forces while allowing the connector to remain accessible on the front side for easy attachment and detachment
Solution Approach 2:
The patent positions the connector at the edge portion of the case rather than directly on the front surface, utilizing the lateral dimension. This edge positioning allows the connector to be easily accessible while the bumper can effectively shield it from front impacts, resolving the contradiction through spatial reconfiguration
2Object-affected harmful factors
If the connector is disposed on the rear side of the case to protect the wire from impact, then wire protection is improved, but the case becomes an obstacle reducing workability in attaching and detaching the connector
Solution Approach 1:
The patent moves the connector from the rear side to the edge portion of the case, utilizing the lateral dimension instead of the front-rear dimension. This repositioning allows the connector to be protected by the bumper from front impacts while remaining easily accessible at the edge for attachment and detachment operations
3Ease of operation
If the connector is positioned at the edge portion of the case, then both wire protection and workability are improved, but the connector structure becomes more complex
Solution Approach 1:
The patent divides the protective function into separate components: the bumper handles impact absorption while the connector handles electrical connection. This segmentation allows each component to be optimized independently, achieving wire protection and workability without requiring a complex integrated structure

AI summary
A connector mounting structure in which a connector is detachably attached to a case, in which the case has a connector fitting portion provided at an edge portion of an upper surface to be connected to an electrical device and with which the connector is fitted, the connector has a contact attached to the connector fitting portion, and a connector shell accommodating at least a part of the contact and the housing, and the connector shell is formed in a hook shape having an extending portion extending outward from above an edge portion of the upper surface of the case and a bent portion bending the outside of the case downward from the extending portion, and the wire extends downward from the lower end of the bent portion, and the contact protrudes from the lower surface of the extending portion and is fitted into the connector fitting portion from above.
