Slider Electrical Connector for Shorter Contact Tails and Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from reduced signal transmission performance due to the presence of useless residual sections in conductive terminals, which are prone to deformation and damage from foreign objects, especially when transmitting high-speed signals.
Innovation Solution
The electrical connector design includes a slider mechanism that moves conductive terminals in and out of the insertion space, with contact tails that are short enough to avoid protruding before insertion, minimizing residual sections and reducing the risk of damage, and incorporates a slider mechanism to protect the terminals during insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the end portion of the conductive terminal extends for a relatively long length to form a bell mouth for guiding insertion, then the tongue plate can be inserted smoothly, but the contact portion is still susceptible to deformation or failure due to contact with foreign objects and the extended portion becomes a useless residual section affecting signal transmission performance
Solution Approach 1:
The patent extracts and removes the useless residual section (end portion) from the conductive terminal. The contact portion is designed to extend only to the necessary length for contact, eliminating the extended bell mouth portion that caused signal transmission degradation while maintaining insertion guidance through other means such as the insulating body structure.
Solution Approach 2:
Instead of extending the contact portion forward to form a bell mouth for guidance, the patent inverts the approach by providing guidance structures on the insulating body or tongue plate, allowing the contact portion to be shortened to the minimum necessary length for electrical contact, thereby eliminating the harmful residual section.
2Ease of operation
If the contact portion extends into the insertion space before tongue plate insertion, then insertion guidance is provided, but the contact portion is exposed to foreign objects causing deformation or failure
Solution Approach 1:
The patent implements preliminary protection by designing the insulating body with protective structures (such as recesses or covers) that shield the contact portion before insertion. The guidance function is achieved through these protective structures rather than through extension of the vulnerable contact portion into the insertion space.
Solution Approach 2:
The insulating body acts as an intermediary between the external environment and the contact portion. It provides both insertion guidance and protection from foreign objects, allowing the contact portion to remain protected while still enabling proper insertion through the insulating body's guidance structures.
3Reliability
If the end portion is shortened to eliminate residual sections, then signal transmission performance improves, but insertion guidance capability may be reduced
Solution Approach 1:
The patent transitions the insertion guidance function from the longitudinal dimension (extended contact portion) to other dimensions such as lateral guidance structures on the insulating body or angular orientation features, allowing the contact portion to be shortened while maintaining guidance capability through different spatial arrangements.
Solution Approach 2:
The insulating body is designed to perform multiple functions: it provides structural support, electrical insulation, insertion guidance through its geometry, and protection of the contact portion. This multi-functionality compensates for the removal of the extended bell mouth portion, maintaining guidance capability without requiring a long contact portion extension.

AI summary
An electrical connector includes an installation body, a first conductive terminal and a slider. The installation body defines an insertion space. The first conductive terminal includes a first contact tail. The first contact tail includes a first contact area and a first extending stub. When the slider is located at a first position, the first contact tail does not protrude into the insertion space. When the slider is located at the second position, the first contact tail protrudes into the insertion space. The present disclosure shortens the useless residual section on the first conductive terminal and thus improves the performance when transmitting high-speed signals.
