Terminal Block Observation Port for Reliable Wire Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal blocks have confined operation spaces that make it difficult for wiring operators to observe the connection between wires and the terminal block, leading to poor contact and unreliable abutting, which complicates wiring operations and reduces efficiency.
Innovation Solution
A terminal block design featuring an observation port, limiting structures, and an elastic piece with clamping and centering sections, ensuring correct assembly and direct visual inspection of the connection, facilitated by interference structures that prevent incorrect mounting and ensure reliable clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wiring hole of the terminal block has a confined operation space, then the terminal block structure is compact, but it is inconvenient for the wiring operator to directly observe the connection between the wire and the terminal block
Solution Approach 1:
The terminal block is segmented to include a separate observation port distinct from the wiring hole. The observation port provides a dedicated viewing area where wiring operators can directly observe the connection between wires and terminal block without interfering with the compact wiring hole structure.
Solution Approach 2:
A transparent or translucent insulating shell is used as an intermediary that allows visual observation through the shell material. This enables wiring operators to see the connection status through the insulating shell without opening the compact structure, thus maintaining both compactness and observability.
2Productivity
If the joint of the wire is inserted into the wiring hole, then the wire connection is established, but it is easy for the elastic piece and the conductor to pinch the insulating layer of the wire
Solution Approach 1:
The insulating shell is designed with a specific structure that prevents the elastic piece and conductor from pinching the insulating layer. The shell includes guiding structures and spacing features that pre-prevent the harmful pinching action before it can occur during wire insertion, ensuring both wiring efficiency and contact reliability.
3Strength
If the elastic piece and the conductor clamp the joint of the wire, then the wire connection is secured, but the abutting between the elastic piece and the joint of the wire is unreliable
Solution Approach 1:
The elastic piece is pre-configured with specific geometric features and mounting structures that ensure proper positioning and reliable abutting with the wire joint. The conductor and elastic piece are pre-assembled with precise tolerances to guarantee consistent clamping force and reliable electrical contact before the wiring operation begins.
