Cable Clamp Structure for Signal Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic apparatuses with wireless communication, cables tend to displace from their shields, leading to increased noise in signal transmission and interference with other components.
Innovation Solution
The electronic apparatus incorporates a support member with first and second clamp portions to securely attach the cable, where the second clamp portion's upper surface is positioned superior to the first clamp portion's lower surface, preventing upward movement and minimizing interference.

Engineering Contradiction Analysis
1Reliability
If a simple shield structure is used to cover the circuit substrate, then the shield can prevent noise from occurring in the signal, but the cable may be displaced from the shield leading to increased noise and interference
Solution Approach 1:
The clamp portion is divided into multiple functional segments: a first clamp portion with an inner surface that contacts the cable, and a second clamp portion with an outer surface that contacts the shield. This segmentation allows each portion to perform its specific function independently while working together to secure the cable to the shield, preventing displacement and maintaining signal quality.
Solution Approach 2:
The clamp portion is positioned within the groove of the shield, with the first clamp portion nested between the groove's opposing surfaces and the second clamp portion extending outward. This nested arrangement integrates the cable fixation mechanism into the existing shield structure, providing stable cable positioning without adding significant external complexity.
2Stability of the object's composition
If the cable is secured to the shield, then cable displacement is prevented, but the clamp portion may interfere with other parts if not properly positioned
Solution Approach 1:
The clamp portion is specifically positioned at a location where the groove is formed on the shield, placing the cable securing function at the optimal location. The first clamp portion is positioned to contact the cable within the groove space, while the second clamp portion extends to contact the shield's outer surface, ensuring proper positioning that prevents interference with other components.
Solution Approach 2:
The clamp portion utilizes three-dimensional spatial arrangement: the first clamp portion is positioned in the radial direction within the groove, while the second clamp portion extends in the axial direction to contact the shield's outer surface. This multi-dimensional positioning secures the cable effectively while avoiding interference with other parts through proper spatial coordination.

AI summary
An electronic apparatus includes a support member, and a cable mounted on the support member. The support member includes a first clamp portion and a second clamp portion mounting the cable on the support member. The first clamp portion includes a first portion being located at upper side of the cable and restricting upward movement of the cable. The second clamp portion is located on the lower side of the cable. At least part of an upper surface of the second clamp portion is located at a level superior to a lower surface of the first portion of the first clamp portion.
