PCB Cable Connector Locking Clamp for Secure Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable assemblies on printed circuit boards are often not secured to cable connectors, leading to potential disconnection issues.
Innovation Solution
A locking device comprising a clamp member and a frame with complementary locking features that apply a compressive force to secure the cable assembly to the connector, preventing disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is added to secure the cable assembly to the cable connector, then the reliability of the connection is improved, but the device complexity increases
Solution Approach 1:
The locking device is integrated within the cable connector housing, with the clamp member and frame nested together to form a compact assembly. The clamp member fits inside the frame, and both components are contained within the cable connector structure, eliminating the need for separate external locking mechanisms while maintaining connection reliability.
Solution Approach 2:
The locking features of the clamp member and frame are combined to form an integrated locking mechanism. The complementary locking features (protrusions and recesses) merge the two components into a unified structure that secures the cable assembly, eliminating the need for separate locking devices and reducing overall complexity.
2Adaptability or versatility
If the locking device is designed to accommodate different sizes of components, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The locking device incorporates adjustable elements that allow the gap between the clamp member and frame to be modified. The clamp member can be positioned at different locations along the frame, and the locking features can engage at multiple positions, enabling the device to adapt to different component sizes while maintaining secure locking. This dynamic adjustability eliminates the need for multiple fixed-size components.
Solution Approach 2:
The clamp member and frame are designed with universal locking features that can accommodate various component sizes. The complementary locking features are configured to work with different gap dimensions, allowing a single locking device design to serve multiple cable assembly and connector size configurations, thereby reducing manufacturing precision requirements while maintaining adaptability.

AI summary
A locking device for securing a cable assembly to a cable connector of a printed circuit board (PCB) includes a clamp member and a frame. The clamp member includes a baseplate and at least one arm extending from the baseplate that has a clamp locking feature. The frame is configured to fit over the clamp member and includes at least one latching member extending therefrom that has a frame locking feature. When the frame is fit over the clamp member, the at least one arm of the baseplate extends through an aperture defined in the frame such that the at least one arm is parallel to the at least one latching member of the frame. The clamp locking feature of the at least one arm is configured to mate with the frame locking feature of the at least one latching member to lock the frame to the clamp member.
