Vehicle Lamp Connector Restricting Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle lamps with LED light sources face issues of electrical disconnection and connector dislodgment due to vibrations and impacts, leading to potential LED failure and damage to the attachment portions.
Innovation Solution
A vehicle lamp design featuring a housing with a restricting section that acts as a stopper for the male connector, a clamp section to secure the wiring cord, and a retainer to maintain electrical connection between the female and male connectors, preventing dislodgment and ensuring stable connection during vehicle travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the male connector is inserted into the female connector without additional securing mechanisms, then the electrical connection can be established, but the male connector may move or fall out due to vibrations and impacts during vehicle traveling
Solution Approach 1:
The housing is designed with a restricting section that preliminarily prevents the male connector from moving in the insertion direction before vibrations or impacts occur. This proactive structural constraint ensures the connector remains in position throughout vehicle operation, maintaining electrical connection reliability without requiring additional securing mechanisms.
2Stability of the object's composition
If the male connector is securely restrained to prevent falling out, then connection stability is improved, but the attachment portion of the female connector may be damaged due to applied loads
Solution Approach 1:
The restricting function is extracted from the female connector's attachment portion and transferred to a separate restricting section in the housing. This separation allows the male connector to be restrained by the housing structure rather than by the female connector's attachment portion, preventing load-induced damage while maintaining connection stability.
Solution Approach 2:
The housing acts as an intermediary structure that provides the restricting section to constrain the male connector. This intermediary mechanism prevents direct load transmission to the female connector's attachment portion, protecting it from damage while still preventing connector dislodgment during vehicle operation.
3Ease of operation
If the wiring cord is allowed to move freely, then flexibility and ease of installation are improved, but the male connector is more likely to fall out due to wiring cord movement during vehicle traveling
Solution Approach 1:
The housing is segmented into distinct functional sections: a restricting section that constrains the male connector and a clamp section that secures the wiring cord. This segmentation allows the wiring cord to be held in a fixed position relative to the connector, preventing cord-induced dislodgment while maintaining overall system flexibility and ease of installation.

AI summary
A vehicle lamp is a vehicle lamp having a light source unit configured to radiate light forward and disposed inside of a lighting body constituted by a housing having an opened front surface and a lens cover that covers the opening of the housing, the light source unit includes a circuit board to which a female connector is attached, and a wiring cord to which a male connector is attached, and the housing includes a restricting section that serves as a stopper of the male connector at a position facing an end portion of the male connector on a side opposite to the male connector in an insertion direction of the male connector in a state in which the male connector is inserted into the female connector.
