Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire connection terminal structures face issues with structural weakness, difficulty in configuration design, and increased operational labor due to wear and tear, leading to unsmooth operation and potential damage.
Innovation Solution
A wire connection terminal structure featuring a metal-made electro-conductive module with arcuate slide guide slots, a rotary button, and an abutment leaf spring, which enhances structural strength and allows for precise and secure guidance of the pin, reducing the required operation force through a gradual increase in the arm of the operation force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If slide slots are made to slightly protrude from the inner wall of the case body to guide the pin, then the guide effect is achieved, but the structural strength of the slide slots deteriorates and they are apt to wear
Solution Approach 1:
The patent introduces a separate guide slot component that acts as an intermediary between the case body and the pin. This guide slot component is detachably mounted to the case body, concentrating the wear on this replaceable part rather than on the case body itself. The guide slot component provides precise guidance for the pin while maintaining the structural integrity of the case body.
Solution Approach 2:
The patent changes the material parameter of the guide slot component by using a metal material instead of the plastic case body material. This material parameter change significantly enhances the structural strength and wear resistance of the guide slots, resolving the contradiction between guide precision and structural strength.
2Measurement precision
If the pin moves gradually close to the rotational axis of the spring support, then the guide effect is achieved, but the arm of the abutment force is shortened requiring increased application force
Solution Approach 1:
The patent employs an arcuate guide slot shape instead of a straight line guide path. This curved geometry allows the pin to follow an arc-shaped trajectory that maintains a more favorable moment arm throughout the motion process. The arcuate shape of the guide slot optimizes the mechanical advantage, reducing the required application force while still achieving precise guidance.
3Ease of manufacture
If the slide slots are disposed on the plastic case body, then the configuration design is simplified, but the structural strength and wear resistance deteriorate
Solution Approach 1:
The patent segments the guide slot function from the case body by using a separate, detachably mounted guide slot component. This segmentation allows the case body to maintain its simple plastic construction for ease of manufacture, while the separate guide slot component provides the required structural strength and wear resistance. The guide slot component can be independently manufactured and replaced when worn.

AI summary
A wire connection terminal structure includes a case main body. Wire plug-in ports are connected with an electro-conductive module. Arcuate slide guide slots are disposed on the electro-conductive module. Rotary buttons are pivotally disposed in the case main body. Each rotary button has a movable section. A pin is disposed on the movable section. The pin is extended into the slide guide slot. At least one abutment leaf spring is pivotally disposed between the rotary button and the electro-conductive module. When a conductive wire passes through the wire plug-in port into the lateral side of the electro-conductive module, the rotary button can be driven to make the movable section gradually displace from a section of the abutment leaf spring near the pivotally rotational center to an outer lateral side. The abutment leaf spring is pushed to engage with the conductive wire.
