Modular Terminal Block Segmentation for Board Size Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing modular DIN rail terminal blocks require separate modules and tooling for different sizes of circuit boards, leading to increased manufacturing and inventory costs due to the need for multiple molds and inventories.
Innovation Solution
The use of standard contact bodies with interchangeable extender bodies of varying lengths to create recesses of different sizes for accommodating various electronic components, allowing for the same modules to support multiple board sizes without the need for multiple molds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate modules are used for different circuit board sizes, then adaptability to different component sizes is improved, but manufacturing complexity and inventory requirements worsen
Solution Approach 1:
The terminal block is divided into a standard contact body and interchangeable extender bodies. The contact body contains the electrical contacts and mounting features, while extender bodies provide different recess depths for different circuit board sizes. This segmentation allows the core electrical function to remain standardized while only the mechanical accommodation portion varies.
Solution Approach 2:
The standard contact body serves multiple functions: providing electrical contacts, mounting the extender body, and supporting different circuit board sizes. By making the contact body universal and compatible with various extender bodies, the system achieves multi-functionality without requiring separate modules for each board size.
2Adaptability or versatility
If separate modules are used for different circuit board sizes, then adaptability to different component sizes is improved, but inventory requirements worsen
Solution Approach 1:
By segmenting the terminal block into a universal contact body and size-specific extender bodies, the inventory burden is reduced. Instead of stocking complete modules for each board size, only extender bodies need to be varied and stored, while the contact body can be a single standardized component.
Solution Approach 2:
The contact body and extender body are combined into a single assembled terminal block unit. This merging allows the standardized contact body to be paired with different extender bodies as needed, reducing the total number of unique components that must be manufactured and inventoried compared to having separate complete modules for each size.
3Adaptability or versatility
If different size modules are used to accommodate different circuit boards, then adaptability is improved, but manufacturing cost worsens
Solution Approach 1:
The terminal block is segmented into a standard contact body that can be manufactured once using a single mold, and interchangeable extender bodies that accommodate different board sizes. This segmentation eliminates the need for multiple complete module molds, reducing tooling costs while maintaining adaptability.
Solution Approach 2:
The contact body is designed as a universal component that can work with extender bodies of various sizes. This universality allows a single contact body design to serve multiple purposes, reducing the number of unique components that need to be manufactured and thereby lowering overall manufacturing costs.

AI summary
A terminal block for mounting on a DIN rail includes a plurality of stacked modules with each module having a contact body and an extender body mounted on the contact body. A circuit board or electronic component is mounted on the contact body and the extender body. Different size extender bodies may be mounted on a common contact body to accommodate mounting different size circuit boards or components on the block.
