Cable Connector Piercing and Positioning Walls for Wearable Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors fail to effectively form electrical connections with thin cables used in wearable smart clothes, leading to functional failures if the connections are not properly established.
Innovation Solution
A cable connector design featuring conductive terminals with a piercing wall and positioning wall, which guide and secure the cable to ensure electrical connection by piercing the outer insulating sheath and positioning the core, minimizing bending or dislocation and maintaining contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connectors are used for thin cables, then the cable can be connected, but the electrical connection is unreliable and the cable may bend or dislocate
Solution Approach 1:
The piercing wall and positioning wall are pre-formed on the conductive terminal before cable insertion. The piercing guiding portion and positioning guiding portion are预先 shaped to guide the cable into the correct position, and the piercing blade portion is ready to pierce the insulating sheath, ensuring reliable electrical connection before the cable is fully inserted
Solution Approach 2:
The positioning wall acts as an intermediary between the conductive terminal and the cable. It includes a positioning guiding portion that guides the cable and a positioning hole that secures the cable, preventing bending and dislocation while ensuring the cable core maintains stable contact with the conductive terminal
2Ease of manufacture
If the connector structure is simplified, then manufacturing is easier, but the ability to securely pierce and position thin cables is compromised
Solution Approach 1:
The piercing wall and positioning wall are merged into a single integrated structure on the conductive terminal. Both walls are formed from the same terminal body, reducing the number of separate components needed while maintaining the precision functions of both piercing and positioning operations
Solution Approach 2:
The conductive terminal serves multiple functions: it provides electrical conduction, includes a piercing wall for penetrating the insulating sheath, and includes a positioning wall for securing the cable. This multi-functionality reduces overall connector complexity while maintaining manufacturing precision

AI summary
A cable connector includes a conductive terminal having a positioning wall and a piercing wall. The piercing wall can pierce an outer insulating sheath of a thin cable to be electrically connected to an inner core of the cable. The positioning wall can position the thin cable to reduce bending or dislocation of the thin cable caused by a force and thus minimize pulling of the core. This ensures electrical connection between the piercing wall and the core of the thin cable, and also prevents the core from being damaged or broken by any pulling force.
