Terminal Block Connector With Pullable Caps For Wire Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal blocks require disassembly and complex procedures for wire connection and disconnection, leading to inefficiencies and increased labor costs, especially when connecting flexible and hard wires, and lack stability in connections.
Innovation Solution
A terminal block connector with pullable caps that create a downward pressing force when pulled upward, allowing wires to be inserted smoothly between flexible metal strips without resistance, and securely fixed upon cap return, enabling instant and stable connections without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional terminal blocks use screw bolts and rivets for wire connection, then wire connection can be achieved, but the connection process becomes complicated and requires disassembly, increasing labor input and time consumption
Solution Approach 1:
The patent extracts the wire insertion function from the traditional screw-fastening mechanism. The terminal block is designed with a insertion hole that directly receives the wire, separating the wire insertion action from the fastening action. This allows wires to be inserted directly without requiring disassembly or complex fastening procedures, significantly simplifying the connection process and reducing time consumption.
Solution Approach 2:
The terminal block is segmented into functional components: an insertion hole for wire reception, a pressing component for clamping, and a limiting component for positioning. This segmentation allows each component to perform its specific function independently, enabling simple wire insertion while maintaining secure connection through the coordinated action of separate pressing and limiting mechanisms.
2Ease of operation
If terminal blocks require disassembly for wire connection, then wire connection can be achieved, but labor input and manufacturing cost increase
Solution Approach 1:
The patent merges the wire insertion function with the connection function into a single integrated structure. The insertion hole is formed directly in the terminal block body, combining the receptacle and the mounting structure into one piece. This eliminates the need for separate fastening components and disassembly steps, simplifying both the manufacturing process and the operation while maintaining secure wire connection.
3Productivity
If existing terminal blocks are used for connecting flexible and hard wires, then wire connection can be achieved, but coordination between two terminal blocks becomes troublesome and connection efficiency decreases
Solution Approach 1:
The terminal block is designed with universal applicability through its standardized insertion hole and multi-functional pressing-limiting mechanism. The same terminal block structure can connect different wire types (flexible and hard wires) without requiring coordination with additional terminal blocks. The limiting component ensures proper positioning for various wire types, enabling single-terminal-block connections that reduce system complexity and improve productivity.

AI summary
A terminal block connector, having a front shell, a rear shell, a metal contact assembly, wire insertion openings, and pullable caps. The metal contact assembly is formed by front flexible metal strips and rear metal strips. The front flexible metal strips are tilted upwardly. Top portions of the rear metal strips have protruding strips. The tilted portions of the front flexible metal strips are positioned below the protruding strips and are in contact therewith. Bulges are provided on the top portion of the front shell each having two troughs on its two sides. One end of a pullable cap is a pulling grip, another end of which contains two symmetrical press strips. The symmetrical press strips are inserted into corresponding troughs. A press tip is formed at a bottom part of each press strip. Recesses corresponding to the press tips are provided on the front flexible metal strips.
