Pull Strap Connector Pressing Member for Controlled Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull strap connectors face challenges in controlling the pulling direction of the pull strap during unlocking, making the process complex and difficult to manufacture.
Innovation Solution
A pull strap connector design that includes a pull strap pressing member fixed to the rear wall, allowing the pull strap to unlock the unlocking device in a downward direction, driving the locking protrusion downwardly, and constraining the pull direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pull strap connector uses a traditional integrated design without a separate pull strap pressing member, then the structure is simpler, but the control over pull strap direction during unlocking is poor and manufacturing is more difficult
Solution Approach 1:
The pull strap connector is divided into separate functional components: the insulating body, the pull strap pressing member, and the pull strap unlocking device. The pull strap pressing member is provided separately from the insulating body and fixed to the rear wall, allowing independent optimization of each component's function and facilitating assembly while achieving precise control over pull strap direction during unlocking.
2Quantity of substance
If the pull strap connector integrates the pull strap pressing member with the insulating body, then the number of parts is reduced, but the manufacturing complexity increases
Solution Approach 1:
The pull strap pressing member is provided separately from the insulating body rather than being integrated into it. This separate provision allows each component to be manufactured independently using optimized processes, then assembled together, reducing overall manufacturing complexity despite increasing the number of discrete parts.
Solution Approach 2:
The pull strap pressing member is pre-formed as a separate component with the specific pressing structure required for controlling pull strap direction, then fixed to the rear wall during assembly. This preliminary preparation of the pressing member simplifies the overall manufacturing process compared to attempting to integrate the pressing function directly into the insulating body molding.
3Ease of manufacture
If the pull strap connector lacks a separate pull strap pressing member, then the manufacturing process is simpler, but the unlocking operation becomes difficult
Solution Approach 1:
By separating the pull strap pressing member from the insulating body, the design achieves precise control over pull strap direction during unlocking through the specifically designed pressing member structure, while maintaining manufacturing simplicity through independent fabrication and assembly of standardized components.
Solution Approach 2:
The pull strap pressing member acts as an intermediary component between the pull strap and the pull strap unlocking device. It mediates the unlocking action by controlling the direction of the pull strap, ensuring that the pulling force is correctly directed to drive the locking protrusion downward, thereby facilitating easy unlocking operation.
4Ease of operation
If the pull strap pressing member is provided separately and fixed to the rear wall, then the pull direction is constrained and unlocking is easier, but the device structure becomes more complex
Solution Approach 1:
The pull strap pressing member serves as a mediating component that constrains the pull strap direction by pressing against it, ensuring the pulling force is correctly directed to drive the locking protrusion downward. This intermediary structure, while adding complexity, enables reliable and easy unlocking operation by controlling the force transmission path.
Solution Approach 2:
The pull strap pressing member provides localized directional control at the specific location where the pull strap interacts with the unlocking mechanism. By concentrating the directional constraint function in this local pressing structure rather than redesigning the entire connector, the solution achieves improved unlocking ease with minimal added complexity.

AI summary
A pull strap connector includes an insulating body, a tongue plate, a cable, a pull strap unlocking device and a pull strap. The insulating body includes a mating space and a rear wall. The tongue plate includes a tongue portion extending into the mating space. The pull strap unlocking device includes a locking piece, and the locking piece includes a locking protrusion. The pull strap connector further includes a pull strap pressing member provided separately from the insulating body and fixed to the rear wall. The pull strap passes through the pull strap pressing member. The pull strap is configured to unlock in a downward direction to move the locking protrusion downwardly. A method of making the pull strap connector is also disclosed.
