Integrated Terminal Structure for Stable Nut Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semiconductor apparatus terminal structures using screws and nuts for fastening are complex, time-consuming, and difficult to miniaturize due to the need for multiple components and high torque resistance, which complicates manufacturing and increases costs.
Innovation Solution
A terminal structure with a pair of plate sections and a connection plate section that integrates a nut-holding mechanism, allowing for secure fastening without separate components, using a single plate-shaped body to stabilize the nut in all directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a separate nut and screw are used for fastening the main terminal, then the fastening strength is sufficient, but the number of components increases and the manufacturing complexity increases
Solution Approach 1:
The patent integrates the nut function directly into the terminal structure by forming a nut receiving groove and engagement protrusions on the terminal body itself. This merging of the nut function into the terminal eliminates the need for separate nut and screw components, reducing component count while maintaining fastening strength through the integrated engagement mechanism.
2Device complexity
If a nut is incorporated into a nut housing section in a case member, then the fastening structure is simplified, but the wall thickness increases and miniaturization becomes difficult
Solution Approach 1:
The patent extracts the nut function from the case member structure and relocates it directly to the terminal body. By taking out the nut housing requirement from the case member, the design eliminates the need for thick walls to accommodate nuts, enabling miniaturization while simplifying the fastening structure through direct terminal integration.
3Stability of the object's composition
If square holes are formed in terminal legs to prevent nut spinning, then the nut stability is improved, but the upper part of the terminal bottom is opened and the nut may drop
Solution Approach 1:
The patent segments the nut retention function into multiple components: the nut receiving groove provides lateral stability, engagement protrusions prevent spinning, and a bottom closure wall prevents dropping. This segmentation of retention functions across different structural elements achieves comprehensive nut stability without leaving the terminal bottom open.
4Reliability
If multiple separate components are used for fastening, then the fastening function is reliable, but the preparation and attachment time increases
Solution Approach 1:
The patent merges the nut function into the terminal structure, creating an integrated fastening component that requires fewer assembly steps. This reduction in component count directly decreases preparation and attachment time while maintaining fastening reliability through the engineered engagement protrusions and receiving groove that ensure proper fastener installation.

AI summary
A terminal structure includes a pair of plate sections including first and second plate sections respectively provided spaced apart from each other in a thickness direction of the nut, a connection plate section extending in the thickness direction of the nut and connects respective one ends of the pair of plate sections to each other, a terminal section protruding from the other end of the first plate section of the pair of plate sections and faces the connection plate section, and a holding section provided at at least one of the connection plate section or the terminal section, and restricting rotation of the nut and movement of the nut in a direction intersecting the thickness direction. The pair of plate sections, the connection plate section, the terminal section, and the holding section are constituted by one plate-shaped body.
