Server Rack Power Clip Transmission Mechanism for High Mating Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of rear power modules in server racks are laborious due to the high mating and unmating forces required by multiple connectors, making the process cumbersome.
Innovation Solution
A transmission mechanism comprising sliding rods, a cross rod, power clips, and elastic separators that assist in overcoming these forces by transferring pushing and pulling forces, allowing for easier connection and disconnection of power clips to and from a busbar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connectors are integrated into the rear power module, then the power supply capacity and connectivity are improved, but the mating force and assembly difficulty increase significantly
Solution Approach 1:
The rear power module is divided into multiple independent power clips, each capable of connecting to the busbar separately. This segmentation allows the total mating force to be distributed across multiple smaller connection points rather than requiring one large force application, making assembly more manageable while maintaining multiple power connections.
Solution Approach 2:
A transmission mechanism is introduced as an intermediary device between the user and the power clips. This mechanism includes force transmission components that amplify and distribute the user's input force to multiple power clips simultaneously, reducing the effort required to overcome the total mating force of multiple connectors.
2Adaptability or versatility
If multiple connectors are integrated into the rear power module, then the power supply capacity is improved, but the disassembly labor and time consumption increase
Solution Approach 1:
The power module is segmented into multiple independent power clips that can be disconnected individually. The transmission mechanism allows a single pulling action on the adapter module to simultaneously disengage multiple power clips from the busbar, converting what would be multiple separate disconnection operations into one unified action, thereby reducing disassembly time.
Solution Approach 2:
The transmission mechanism serves as a mediator that translates a single user input force into simultaneous unmating forces applied to multiple power clips. This force multiplication and distribution mechanism reduces the total time required for disassembly by enabling parallel disconnection of multiple connectors through a single operational motion.
3Strength
If a rigid support frame is used in the transmission mechanism, then the structural strength is improved, but the risk of breaking under high mating force increases
Solution Approach 1:
The support frame material parameter is changed from rigid to elastic. This elastic material can dynamically adjust its stiffness to buffer and absorb the high mating forces during assembly and disassembly operations. The elastic deformation capability allows the frame to flex under load and return to its original shape, preventing permanent damage or breaking while maintaining sufficient structural strength to support the transmission mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates faster and more convenient assembly and disassembly of electronic components in server racks by reducing the manual effort needed to connect and disconnect power clips, enhancing the structural integrity with an elastic support frame.
Implementation Method 1
a support frame of the transmission mechanism is made of elastic metal material, which can buffer at least one of a part of the mating force, the pushing force and the pulling force to prevent the cross rod of the transmission mechanism from breaking
Implementation Method 2
a separator of the transmission mechanism can store an elastic force to assist in overcoming an unmating force of the power clip from the busbar

AI summary
A transmission mechanism includes a first sliding rod, a second sliding rod, a cross rod and at least one power clip. The second sliding rod is parallel to the first sliding rod. An end of the cross rod is connected to the first sliding rod, and another end of the cross rod is connected to the second sliding rod. The at least one power clip is fixed to the cross rod. The transmission mechanism may be applied to an adapter module and a data processing device to make the disassembly and assembly of an electronic component and a rack faster and more convenient.
