Server Cable Threading Tray for Single-Person PCIe Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of servers with multiple layers of nodes is hindered by high labor and time costs due to the complex wiring of cables between the computation node layer and the PCIE module node layer, particularly when requiring simultaneous operation by multiple persons for threading.
Innovation Solution
A threading device with a tray and cable temporarily-storing member, featuring a clamping mechanism and cable clamps, allows cables to be fixed and managed efficiently, enabling single-person assembly by sequential installation of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wiring holes are provided at the front and rear of the mainboard for direct cable connection, then signal integrity is satisfactory, but multiple persons are required for threading which increases labor cost and time cost
Solution Approach 1:
The patent divides the cable management process into two independent stages: first, cables are threaded through wiring holes in the mainboard (front end); second, cables are routed through the tray with cable temporarily-storing members (rear end). This segmentation allows the front-end threading to be completed without requiring simultaneous multi-person coordination at the rear end, thereby maintaining signal integrity while reducing labor requirements.
Solution Approach 2:
The tray with cable temporarily-storing members acts as an intermediary device between the mainboard and the PCIE module node layer. It provides a temporary holding position for cables during the assembly process, allowing cables to be organized and stored in an orderly manner without requiring multiple persons to simultaneously handle and coordinate the threading operation, thus improving assembling efficiency while maintaining proper cable routing.
2Ease of manufacture
If cables are routed from two sides of the mainboard to the rear end using CMA technique, then connection is achieved, but cable length is too long resulting in unsatisfactory signal integrity
Solution Approach 1:
The patent introduces a spatial dimension by adding the tray structure that extends from the mainboard toward the rear end of the server crate. This allows cables to be routed through a dedicated intermediate path rather than directly from the mainboard to the rear end, effectively shortening the cable length and improving signal integrity while maintaining the ease of connection through the structured tray system.
3Ease of operation
If two persons lift the computation node layer while another person performs threading, then proper cable routing is achieved, but labor cost and time cost are high
Solution Approach 1:
The cable temporarily-storing members in the tray provide a self-service function by automatically holding and organizing cables in place during the assembly process. This eliminates the need for multiple persons to simultaneously coordinate lifting and threading operations, as the structure itself maintains cable position and routing, allowing single-person operation while preserving proper cable installation.

AI summary
A threading device and a server, which relates to the technical field of cable threading. The threading device includes: a tray (100), wherein the tray (100) is for being installed inside a server crate, and located over a PCIE module layer (700), the tray (100) is provided with a wiring hole, and the wiring hole is for the penetration by a cable; and a cable temporarily-storing member (200) provided at the tray (100), wherein the cable temporarily-storing member (200) is for fixing the cable that has passed through the wiring hole. In the threading device, by providing the tray (100), and providing the wiring hole and the cable temporarily-storing member (200) on the tray (100), the cable of the PCIE module layer (700) may be caused to pass through the wiring hole, subsequently be fixed by the cable temporarily-storing member (200), and subsequently be connected to the computation layer (600). In the connecting process, the threading device and the computation layer (600) are sequentially installed, which does not require simultaneous operation by multiple persons, thereby simplifying the process of the assembling of the server, increasing the efficiency of the assembling of the server, and reducing the labor cost and the time cost.
