High Frequency Plug Cable Organizer With Guide Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high frequency plugs experience interference among the 8 wires, leading to deformation of the cable and disruption of signal transmission due to unchanged twist pitch when the holding down block is stamped against the cable.
Innovation Solution
A high frequency plug design featuring an electrically insulative housing, a load bar, and a cable organizer with top, bottom, left, and right guide grooves, and a vertical opening hole, which maintains the twist pitch of the twisted pairs and reduces cross-talk between specific wire pairs, using a holding down block with a smoothly arched recess to prevent deformation and enhance signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding down block is stamped against the cable to secure it, then the cable is firmly held in position, but the cable deformation disrupts the twist pitch of twisted pairs and causes signal transmission disruption
Solution Approach 1:
The cable securing function is segmented into multiple components: the holding down block secures the cable bundle, while guide grooves in the cable organizer secure individual twisted pairs. This segmentation allows each component to perform its function without deforming the cable structure, maintaining twist pitch uniformity while achieving reliable cable holding.
Solution Approach 2:
The cable organizer acts as an intermediary between the holding down block and the twisted pairs. It provides guide grooves that gently guide and secure each twisted pair without direct stamping pressure, preventing deformation while maintaining secure positioning. This intermediary structure resolves the contradiction between firm holding and pitch preservation.
2Reliability
If the twist pitch remains unchanged during cable securing, then signal transmission is maintained, but the cable cannot be firmly secured against interference
Solution Approach 1:
The cable management system is segmented into the holding down block for overall cable securing and the cable organizer with guide grooves for individual twisted pair management. This segmentation allows the cable to be firmly secured against external interference while the guide grooves maintain the twist pitch of each pair, preventing signal transmission disruption.
Solution Approach 2:
The cable organizer serves as an intermediary structure that provides mechanical support and positioning for twisted pairs. Its guide grooves gently constrain the cables without deformation, allowing firm securing while maintaining signal transmission quality through preserved twist pitch.
3Ease of manufacture
If conventional cable securing methods are used, then assembly is simple, but cross-talk between wire pairs increases and transmission quality deteriorates
Solution Approach 1:
The cable organizer merges multiple functions into a single component: it provides guide grooves for securing twisted pairs, maintains their geometric arrangement, and reduces cross-talk between pairs. This integrated structure achieves improved transmission quality without significantly complicating the assembly process, as the cable organizer is installed as a single piece.
Solution Approach 2:
The cable organizer acts as an intermediary structure that improves transmission quality by providing guided pathways for twisted pairs. It maintains proper spacing and orientation between pairs, reducing cross-talk while preserving the simplicity of the overall assembly process through its pre-formed structure.

AI summary
A high frequency plug formed of a housing, a load board and a cable organizer is disclosed. The cable organizer has top, bottom, left and right guide grooves for guiding the four twisted pairs of the cable, and a vertical opening hole in communication between the top and bottom guide grooves to enhance cross talk between the pair of the third and sixth wires and the pair of the fourth and fifth wire, thereby achieving de-embedded effect and improving the transmission quality. The cable organizer is molded from plastic with conductive material or EMI/RFI shielding material, eliminating interference and improving the transmission quality.
