Electrical Connector Movable Member Wire Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical connectors that connect conducting wires to printed circuit boards (PCBs) face difficulties in easily releasing the wire due to the barb structure of the conductive clamp, making it hard to pull out the wire and manually open the clamp, especially as connectors become miniaturized.
Innovation Solution
An electrical connector design featuring a housing with a conductive clamp, movable member, and sliding channels that allows the conducting wire to be easily detached by moving a movable member to open the clamping pieces, facilitated by oblique sliding channels and a reset mechanism, enabling convenient clamping and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a barb structure is used in the conductive clamp to secure the conducting wire, then the wire connection reliability is improved, but the ease of operation deteriorates because it becomes very difficult to pull out the conducting wire and manually open the clamp
Solution Approach 1:
The conductive clamp is designed with movable first clamping pieces that can dynamically change their position between a clamping state (secured by the movable member) and an opening state (released by the movable member). This dynamic capability allows the clamp to both securely hold the wire during use and enable easy detachment when needed, resolving the contradiction between connection reliability and ease of operation.
Solution Approach 2:
The movable member acts as an intermediary mechanism between the operator and the first clamping pieces. By interacting with the releasing pieces on the clamping pieces, the movable member mediates the force transmission to open or close the clamping pieces, enabling easy wire detachment without requiring direct manual manipulation of the barbed clamp structure.
2Volume of moving object
If the electrical connector is miniaturized to reduce size, then the volume is reduced, but the ease of operation deteriorates because it becomes difficult for operators to manually open the conductive clamp
Solution Approach 1:
The movable member provides a dynamic amplification mechanism that allows operators to easily open the clamp even in miniaturized connectors. The movable member's movement translates into amplified force on the releasing pieces, enabling manual operation of the clamp despite the reduced size of the overall connector structure.
Solution Approach 2:
The movable member serves as a mechanical intermediary that amplifies the operator's input force to effectively open the clamp. This intermediary mechanism compensates for the size reduction, allowing easy manual operation of miniaturized connectors without requiring excessive force from the operator.
3Reliability
If the first clamping pieces are designed to tightly clamp the conducting wire, then the connection reliability is improved, but the device complexity increases due to the need for additional releasing pieces and movable member mechanisms
Solution Approach 1:
The movable member combines multiple functions into a single component: it directly clamps the conducting wire, indirectly controls the opening/closing of the first clamping pieces through interaction with releasing pieces, and provides the mechanical advantage needed for easy operation. This merging reduces the number of separate components needed while maintaining both tight clamping and ease of operation.
Solution Approach 2:
The movable member is designed as a multi-functional component that simultaneously performs clamping, releasing control, and force amplification functions. This universal design achieves tight wire connection and easy detachment capability without requiring separate dedicated mechanisms for each function, thereby controlling device complexity.

AI summary
An electrical connector includes a housing which is provided with an installation cavity and a jack. A conductive clamp and a movable member are configured in the housing. The conductive clamp is provided with at least one pair of first clamping pieces and at least one pair of releasing pieces. The first clamping pieces and the releasing pieces extend into the installation cavity. The movable member is capable of moving back and forth along the installation cavity. A conducting wire is capable of passing through the jack and is inserted into one pair of first clamping pieces. The movable member is capable of moving forward along the installation cavity, and abutting on one pair of releasing pieces, to force the releasing pieces and drive the first clamping pieces to open outward, so that the conducting wire is capable of detaching from the first clamping pieces.
