Terminal Block Leaf Spring Movement Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing terminal block design increases manufacturing costs due to the need for additional components to support the housing's opening surface, which complicates the structure and raises production expenses.
Innovation Solution
A terminal block design featuring a housing with integrated insulation, a holding portion, and a leaf spring mechanism that includes a terminal electrode and leaf spring portion, where the leaf spring's moveable portion is restricted in the width direction by a movement restriction portion, eliminating the need for separate support components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support portion is added to cover the opening surface and support members in the holding portion, then the structural stability is improved, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The support portion is integrated into the housing as a unified structure. The housing includes both the opening surface and the support portion that extends to support the terminal electrode portion and leaf spring portion, eliminating the need for separate support components while maintaining structural stability.
Solution Approach 2:
The housing serves multiple functions: it provides the opening surface for wire insertion, acts as a support structure through its integrated support portion, and maintains the positional relationship between various components. This multi-functionality reduces the need for additional specialized support components.

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
This design reduces the number of components and manufacturing costs while maintaining functionality by preventing the leaf spring from falling off and ensuring accurate connection status display through a linear motion of the display-use moveable member.
Implementation Method 1
a leaf spring portion (30) arranged in the holding portion (10)... a moveable portion (32) that is provided at the other end of the leaf spring portion (30) and is disposed between the fixed portion (31) and the terminal electrode portion (20)... being moveable relative to the fixed portion (31)

AI summary
A terminal block includes a housing having insulation properties, the housing having a holding portion provided in the housing and a terminal connection surface, a first opening portion through which a conductor portion of an electric wire can be inserted and pulled out and a second opening portion that is adjacent to the first opening portion and through which a jig can be inserted and pulled out being arranged in series in an array direction on the terminal connection surface and each communicating with the holding portion, and an opening surface being provided on a side of the holding portion in a width direction intersecting the array direction and a direction intersecting the terminal connection surface, and a terminal electrode portion and a leaf spring portion arranged in the holding portion. The housing is provided with a first movement restriction portion that restricts the movement of the moveable portion of the leaf spring portion in the width direction.
