Cable Connector Latch With Pulling Member For High Retaining Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable connectors with resilient latches cannot withstand the increased force required to detach them from electronic or storage components as the number of pins increases, leading to premature detachment of the latch before the connector is fully removed.
Innovation Solution
The design incorporates a casing with a resilient latch and a pulling member, where the latch is securely fixed using protrusions and hooks, allowing the latch to withstand larger pulling forces by adjusting its position and maintaining engagement with the casing, ensuring the connector detaches from the socket when the pulling member is pulled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of pins in the cable connector is increased to improve transmitting capacity, then the transmitting capacity is improved, but the pulling force required to detach the connector increases and the resilient latch cannot withstand such force
Solution Approach 1:
The latch is divided into a resilient latch portion and a rigid latch portion, separating the functions of engagement (resilient) and force transmission (rigid). This segmentation allows the resilient latch to engage the socket while the rigid latch transmits the pulling force from the pulling member to detach the connector, solving the problem of the resilient latch being unable to withstand the increased pulling force from multiple pins.
Solution Approach 2:
The latch combines materials with different mechanical properties - a resilient material for the resilient latch portion and a rigid material for the rigid latch portion. This composite structure allows the latch to both engage the socket resiliently and transmit the high pulling forces required when multiple pins are connected, resolving the contradiction between resilience and force withstanding capability.
2Force
If the resilient latch is made more robust to withstand larger pulling force, then the force resistance is improved, but the volume of the connector increases
Solution Approach 1:
By segmenting the latch into resilient and rigid portions, each with optimized dimensions for its specific function, the overall volume is minimized while achieving the required force resistance. The rigid latch portion can be slender since it only needs to transmit force, while the resilient portion is compact as it only needs to engage the socket.
Solution Approach 2:
The rigid latch portion and resilient latch portion are merged into a single integrated latch structure, allowing force transmission and engagement functions to be combined in a compact arrangement that reduces overall connector volume compared to using separate components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables the resilient latch to endure larger pulling forces, ensuring the connector can be reliably detached from electronic or storage components without separating from the casing, even when the connector is tightly clamped.
Implementation Method 1
The resilient latch comprises a lower portion and an upper portion... the lower portion has a lower through hole... the upper portion has at least one upper through hole... While the pulling member is pulled away from the latch along a first direction, the pulling member pulls the upper portion toward the lower portion along a second direction so as to adjust a position of the protrusion

AI summary
A cable connector configured to secure a cable is provided. The cable connector has a casing, a latch, and a pulling member. The casing is configured to secure an end of the cable. The latch has a lower portion and an upper portion. The lower portion is secured on the casing and has a lower through hole. The upper portion has at least one upper through hole and at least one protrusion. The pulling member is connected with the upper through hole and penetrates the lower through hole. While the pulling member is pulled away from the latch along a first direction, the pulling member pulls the upper portion toward the lower portion along a second direction, so as to adjust a position of the protrusion. Thus, the latch may not be separated from the casing when a user pulls the pulling member.
