Solution Overview
Problem
Existing connection terminals lack sufficient mechanical strength and secure mounting capabilities, leading to potential instability and failure under pressure.
Innovation Solution
A connection terminal design featuring a primary locking portion with a first stopping portion, reinforcing portion, and secondary locking structures, including a retreat prevention protrusion, is implemented. This design includes a support base, mounting side wall, and support wall with specific protrusions and holes for enhanced stability and secure fitting within a housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple connection terminal structure is used, then manufacturing cost is reduced, but mechanical strength and mounting security deteriorate
Solution Approach 1:
The connection terminal is divided into multiple functional segments: a body portion, a primary locking portion with first stopping portion, a secondary locking portion with second stopping portion, and a wire connecting portion. Each segment performs a specific function, allowing the structure to achieve high mechanical strength through distributed load paths while maintaining manufacturing efficiency through modular design
Solution Approach 2:
The locking portions are nested within the body structure, with the first stopping portion integrated into the primary locking portion and the second stopping portion integrated into the secondary locking portion. This nesting eliminates the need for separate mounting brackets or additional fastening components, reducing overall part count and manufacturing complexity while maintaining structural integrity
2Device complexity
If a simple connection terminal structure is used, then device complexity is reduced, but mounting security and reliability deteriorate
Solution Approach 1:
The first stopping portion is pre-configured with an inclined segment that automatically engages with the housing during the insertion process. This preliminary action ensures that the primary locking occurs before the terminal is fully inserted, providing immediate mounting security. The second stopping portion similarly provides a secondary preliminary locking action that further secures the terminal in place
Solution Approach 2:
The locking portions are designed with dynamic engagement characteristics. The inclined segment of the first stopping portion allows for smooth insertion while the parallel segment provides rigid locking once inserted. The second stopping portion similarly transitions from insertion to locked position, creating a dynamic mounting process that ensures reliable fixation without requiring complex adjustment mechanisms
3Strength
If reinforcement structures are added to the connection terminal, then mechanical strength is improved, but manufacturing complexity increases
Solution Approach 1:
The reinforcing portions are merged with the locking portions as integral structures. The first reinforcing portion is combined with the first stopping portion, and the second reinforcing portion is combined with the second stopping portion. This merging provides structural reinforcement to enhance mechanical strength while avoiding the need for separate reinforcement components, thereby maintaining manufacturing simplicity
Solution Approach 2:
The reinforcing portions are strategically positioned at specific locations where mechanical strength is most needed: the first reinforcing portion is located at the first stopping portion to strengthen the primary locking mechanism, and the second reinforcing portion is located at the second stopping portion to strengthen the secondary locking mechanism. This localized reinforcement provides maximum structural benefit with minimal added complexity
