Cable Retention Frame for Electronic Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During electronic assembly, electrical cables, such as coaxial cables, often get pinched between enclosure portions, preventing proper seating and causing interference with the assembly's electrical components, leading to performance issues and manufacturing challenges.
Innovation Solution
The electronic assembly incorporates a frame with arcuate members and grooves that act as retainers to securely hold coaxial cables, preventing them from interfering with the seating of enclosure portions and maintaining a stable path to reduce radio frequency coupling, using materials like plastics and elastomers for elastic deformation, and includes thermal pads for heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical cable is routed between connector and internal circuitry during manufacturing, then electrical connection is established, but cable becomes pinched between enclosure portions or prevents proper seating
Solution Approach 1:
The frame with arcuate members is pre-configured to receive and retain the cable before enclosure portions are mated together. This preliminary action ensures the cable is secured in its proper path prior to assembly, preventing pinching and interference during the mating process.
Solution Approach 2:
The frame acts as an intermediary structure between the cable and the enclosure portions. It provides a dedicated retention mechanism that isolates the cable from potential pinching points, allowing the cable to be routed through the assembly without interfering with enclosure seating.
2Reliability
If cable is secured tightly to prevent movement, then cable retention is improved, but cable flexibility and signal transmission may be compromised
Solution Approach 1:
The arcuate members provide a curved retention path for the cable, allowing the cable to bend smoothly along the arc rather than being rigidly constrained. This curved geometry maintains cable flexibility and signal transmission while still providing stable positional retention during assembly.

AI summary
An electronic assembly comprises a circuit board having one or more electronic components mounted on the circuit board. The circuit board has a first side and a second side opposite the first side. The electronic assembly has a lower enclosure and an upper enclosure for mating with the lower enclosure to form a housing to hold the circuit board. A frame overlies the first side or the second side of the circuit board. The frame comprises a first retainer for retaining coaxial cable. The first retainer comprises a first pair of opposing arcuate members extending from the frame.
