Solution Overview

Problem

Conventional wiring terminals lack overall structural strength and exhibit loose connections, resulting in insufficient clamping force and poor contact during signal transmission due to their open shape and composition of separate parts.

Innovation Solution

A wiring terminal structure featuring an integrally formed box with a leaf spring and a plugging element, where the leaf spring extends from the box to form a clamping end that abuts against a convoluted recess, providing enhanced structural integrity and clamping force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the body is made open in shape to simplify structure, then ease of manufacture is improved, but overall structural strength deteriorates

Engineering Contradiction:
Improveease of manufactureVSAvoidoverall structural strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent merges the body and closing member into a unified structure where the closing member integrates with the body to form a closed shape. This combining approach maintains ease of manufacture through simple assembly while achieving the structural strength of a closed configuration, directly resolving the contradiction between open shape simplicity and structural integrity.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If the wiring terminal is composed of different parts to facilitate assembly, then ease of manufacture is improved, but structural looseness increases

Engineering Contradiction:
Improveease of manufactureVSAvoidstructural looseness
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The closing member is designed to be pre-formed with specific geometric features that complement the body structure. When assembled, these pre-configured features interlock to eliminate interstices and prevent structural looseness, maintaining ease of assembly while achieving tight structural integration.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If separate parts are used to form the wiring terminal, then ease of manufacture is improved, but clamping force deteriorates

Engineering Contradiction:
Improveease of manufactureVSAvoidclamping force
Core Design Contradiction:
Ease of manufactureVSForce

Solution Approach 1:

The leaf spring is integrated with the closed structure formed by the body and closing member, creating a unified force transmission path. This merging eliminates energy loss at interfaces between separate parts, ensuring that the elastic force generated by the leaf spring is fully transmitted to the clamping action, thereby maximizing clamping force while maintaining manufacturing simplicity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A wiring terminal structure of the present invention includes a box and a plugging element. The box is an integrally formed unitary unit and includes an upper wall, side walls, a lower wall, a hole, and a leaf spring. The upper wall, the side walls, and the lower wall define a space. The hole is formed on the upper wall and enables communication between the space and the outside of the box. The leaf spring extends upward from the lower wall to reach the space and forms an end protruding from the hole. The plugging element includes a plugging portion and a clamping portion having upper and lower clamping leaf springs. The plugging portion is inserted into the space and plugged into the box. The end of the leaf spring abuts against the plugging portion and is pressed downward by the plugging portion to lie in the space.
