Lateral Cable-Soldering Connector Layout for Shorter Insertion Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors are unable to effectively miniaturize while maintaining electrical connection due to their fixed length, which is not adaptable to the narrowing space in modern electronic devices.
Innovation Solution
The electrical connector design features terminals with a clip, connecting, and soldering section, where the cable is soldered laterally to the soldering section, allowing the connector to be miniaturized without compromising electrical connection by arranging terminals in a lateral direction and using a metallic shell for interface assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the electrical connector uses traditional wiring method with terminals arranged along the insertion axis, then the electrical connection relationship is maintained, but the length of the connector cannot be effectively shortened
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional linear arrangement of terminals along the insertion axis to a lateral arrangement perpendicular to the insertion axis. The terminal body extends along the insertion axis while the soldering section extends laterally, creating a three-dimensional configuration that reduces connector length in the insertion direction while preserving electrical connectivity through the lateral soldering path.
2Volume of moving object
If the electrical connector is miniaturized to fit narrow space, then the space requirement is satisfied, but the electrical connection functionality may be compromised
Solution Approach 1:
The patent implements nesting by integrating the soldering section within the terminal structure itself, where the soldering section is formed as an integral part of the terminal body. This nested configuration allows the cable to be soldered directly to the terminal without requiring external connection elements, thereby miniaturizing the overall connector volume while ensuring reliable electrical connection through the integrated soldering path.
3Ease of manufacture
If the terminal structure is simplified for standardized production, then manufacturing complexity is reduced, but the ability to achieve lateral soldering connection may be affected
Solution Approach 1:
The patent applies segmentation by dividing the terminal into distinct functional sections: a terminal body portion that extends along the insertion axis and maintains structural integrity, and a soldering section that extends laterally for cable connection. This segmented design allows each section to be optimized independently - the terminal body for standardized manufacturing and the soldering section for lateral connectivity - while maintaining a unified terminal structure that achieves both manufacturing efficiency and functional adaptability.

AI summary
An electrical connector for soldering with a cable is provided. The electrical connector includes an insulating body, a plurality of terminals, and a metallic shell. The terminals are disposed in the insulating body and arranged in a lateral direction. Each of the terminals has a clip section, a connecting section, and a soldering section. The metallic shell is assembled to the insulating body to form an interface of the electrical connector for connecting to another electrical connector, the clip section is close to the interface, the soldering section is away from the interface, and the cable is soldered to the soldering section of at least one of the terminals in the lateral direction.
