Cable Fixing Assembly with Rotating Lock Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-detachable cable designs for electronic devices limit appearance options and increase manufacturing costs due to the need for additional assembly procedures and tools, especially when trying to hide cables while maintaining a sleek appearance.
Innovation Solution
A cable fixing assembly featuring a cable head with a stress release portion, joint portion, and lock body, combined with a fixing board having a joint hole, no-return blocks, and hooks, allowing the cable to be securely fixed without being detachable and hiding exposed conductive wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable is fixed using a nut-outer thread design, then the cable can be securely fixed to the lower housing, but additional assembling procedures and tools are required, increasing manufacturing cost
Solution Approach 1:
The invention extracts the threading function from a separate nut component and integrates it directly into the joint portion of the cable. The joint portion is formed with external threads that directly engage with internal threads in the lower housing, eliminating the need for a separate nut component and reducing assembly complexity while maintaining secure fixation
Solution Approach 2:
The invention merges the cable joint portion and the fixing nut into a single integrated joint portion structure. The external threads are formed directly on the joint portion, combining what were previously separate components (cable end and nut) into one unified element, thereby simplifying the assembly process and reducing manufacturing cost
2Reliability
If the cable is fixed at the assembling position of upper housing and lower housing, then the joint portion can be sandwiched between joint notches, but the appearance of the electronic device is largely limited
Solution Approach 1:
The invention segments the cable fixation function from the housing assembly structure. The joint portion with external threads can be independently positioned and fixed at various locations on the lower housing, rather than being constrained to a specific joint between upper and lower housings. This allows the cable to be fixed at different positions (bottom, side, etc.) to achieve desired appearance effects while maintaining secure fixation
Solution Approach 2:
The joint portion is designed with universal threading capability that can engage with corresponding threaded holes in various positions on the lower housing. This multi-functional design allows the same joint portion to be used for fixing the cable at different locations (bottom, side walls, etc.), providing design flexibility for different appearance requirements while maintaining reliable fixation
3Ease of operation
If the cable is made detachable using plug-socket design, then the cable can be easily connected and disconnected, but the manufacturing cost increases
Solution Approach 1:
Instead of designing a detachable plug-socket system, the invention inverts the approach by creating a non-detachable fixed connection using integrated external threads on the joint portion. The cable is permanently fixed to the lower housing through threaded engagement, eliminating the need for separate plug and socket components while reducing manufacturing cost

AI summary
A cable head of a cable of a cable fixing assembly includes a joint portion and a lock body. The lock body is disposed on two opposite side surfaces of one end of the joint portion and extends therefrom. A fixing board of a cable fixing assembly includes a joint hole, a no-return block and a hook. The joint hole is formed through the fixing board. The no-return block is formed adjacent to the joint hole and includes a guiding slope and a no-return surface. The hook is disposed on the fixing board to fix conductive stranded wires in the cable body. The joint portion and the lock body are inserted into the joint hole and are rotated by an angle, and the lock body moves on the guiding slope and then is locked by the no-return surface.
