Compression Connector Substrate Fixing Without Nuts or Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression connectors require separate nuts and screws for attachment, leading to increased work hours and risk of nut loss during assembly.
Innovation Solution
A connector design with press-fit pins or slip-stop pins that secure the connector to the substrate, eliminating the need for nuts and reducing assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screwing method is used to fix the compression connector to the substrate, then the connector can be securely attached, but the attachment work becomes complex and time-consuming due to the need for separate nuts and screws
Solution Approach 1:
The patent integrates the screw and nut functions into a single integrated screw component. The screw includes an integrated nut portion formed directly on the screw body, eliminating the need for separate nuts. This merging of components simplifies the attachment structure while maintaining secure fixation capability.
Solution Approach 2:
The patent extracts the nut function from being a separate component and incorporates it directly into the screw structure. The integrated nut portion is formed as part of the screw body, allowing the screw to perform both fastening and nut functions simultaneously, thereby reducing the number of parts and assembly complexity.
2Reliability
If screwing method with separate nuts is used, then secure attachment is achieved, but work manhours increase and nuts are likely to be lost during assembly
Solution Approach 1:
The patent combines the screw and nut into a single integrated component. The integrated screw includes an integrated nut portion that is formed directly on the screw body, eliminating the need for separate nuts. This reduces the number of components to be handled during assembly, improving productivity and reducing the risk of nut loss.
Solution Approach 2:
The integrated screw design allows the screw itself to provide both the fastening function and the nut function. The integrated nut portion is self-contained within the screw structure, eliminating the need for separate nut components that could be lost during assembly operations.
3Reliability
If multiple separate components (nuts and screws) are used for attachment, then secure fixation is achieved, but the attachment process becomes more difficult and time-consuming
Solution Approach 1:
The patent merges the screw and nut into a single integrated screw component. The integrated nut portion is formed directly on the screw body, allowing the operator to perform attachment with a single component instead of coordinating multiple separate parts, thereby improving ease of operation.
Solution Approach 2:
The patent extracts the nut function from being a separate handleable component and incorporates it into the screw structure. This eliminates the need for operators to separately handle and coordinate nuts during assembly, making the attachment operation simpler and more intuitive.
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 easy and secure attachment of the compression connector to the substrate with reduced man-hours and no risk of pin loss, enhancing workability and stability.
Implementation Method 1
The elastic spring section (23) having a spring property is provided between the substrate connecting section (22) and the contact section (24). The elastic spring section (23) of the contact (20) exerts the spring property to generate a contact pressure between the second circuit board (40) and the contact (20).
Implementation Method 2
at least one or more fixing parts piercing through a hole formed in the substrate and functioning as slip-off prevention for the compression corrector with respect to the substrate are formed on the substrate side of the vertical surface

AI summary
A compression connector is fixed to a substrate with a small motion. In a connector with substrate, a compression connector pressed against and connected to a connection target object and a substrate are attached. The connector with substrate includes a substrate including a hole; and a compression connector disposed on the substrate and including contacts that are in contact with the substrate, a housing to which the contacts are fixed, and a cover shell that has a top surface disposed in parallel to the substrate and a vertical surface vertically extending to the substrate from the top surface, and that covers an upper surface portion of the housing. The vertical surface includes at least one fixing part at a substrate side, piercing through the hole formed in the substrate, and functioning as slip-off prevention for the compression corrector with respect to the substrate.
