Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push-in connectors face issues with secure and stable electrical connections, especially in changing environments, as they often rely on 'one-point-and-one-line' positioning mechanisms that can lead to conductor deformation and increased impedance, causing potential fires and malfunctions.
Innovation Solution
A 'two-points-and-one-line' push-in terminal and connector design, featuring a terminal body with U-shaped slits and spring fingers, securely positions the conductor at the stripped end of an electric wire, preventing axial rotation and ensuring stable electrical connections even in vibrating environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional 'one-point-and-one-line' positioning mechanism is used, then the connector structure is simple, but the conductor becomes deformed and twisted in violent environments
Solution Approach 1:
The patent transitions from a one-point-and-one-line positioning mechanism to a two-points-and-one-line positioning mechanism. This adds another constraint point in the same dimensional space, creating a more stable triangular constraint system that prevents conductor rotation and deformation while maintaining structural simplicity.
2Productivity
If the conductor is pushed into the connector without proper positioning, then the connection process is fast, but the conductor transmits electrical signals unstably
Solution Approach 1:
The patent implements preliminary positioning action through the two-points-and-one-line mechanism that establishes the correct conductor position before electrical connection is made. This pre-positioning ensures stable signal transmission from the start without requiring additional adjustment steps, maintaining fast connection speed while ensuring reliability.
3Ease of operation
If the conductor is allowed to rotate axially in the connector, then the insertion process is easy, but the impedance increases and fires may occur
Solution Approach 1:
The patent applies preliminary anti-action by designing the two-points-and-one-line positioning mechanism to preemptively prevent axial rotation of the conductor. The second positioning point creates a constraint that counteracts any rotational force before it can cause impedance increase or heating, while still allowing easy insertion through the connection port.

AI summary
A two-points-and-one-line push-in terminal capable of secure positioning includes a terminal body and a busbar, and can be mounted in a housing to form a connector. The terminal body is formed by stamping and bending an elastic metal plate, has a U-shaped longitudinal cross section, and includes a front upstanding insertion leg, a horizontal joining foot, and a rear upstanding insertion leg. The elastic metal plate can be divided by at least two slits into at least four independent sections, each having a U-shaped slit defining a pressing spring finger and a pressing frame. The busbar can be mounted on the horizontal joining foot. An electric wire can be passed through a corresponding pair of the U-shaped slits so as to abut against the free ends of the corresponding pressing spring fingers and the busbar and be restrained in the corresponding pressing frames, which serves as the two-points-and-one-line positioning mechanism.
