Connector Fixing Structure with Wire Binding Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vertical-type connectors require wires to be bent 90 degrees, leading to inconsistent wire lengths and irregular distortions, causing the case to be difficult to engage and fix, and increasing the risk of wires being pulled out unintentionally.
Innovation Solution
A fixing structure for connectors comprising a wire binding block, upper and lower shells with engaging structures, and stopping blocks to securely clamp and prevent wire pull-out, ensuring consistent wire positioning and engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wires are bent 90 degrees to achieve vertical-type connector installation, then the connector can be installed in vertical circumstances, but the wire lengths become inconsistent and the case becomes difficult to engage and fix
Solution Approach 1:
The wire binding block is pre-formed with stopping blocks positioned to engage with the curve section of the wires before insertion. This preliminary preparation ensures that when wires are bent to 90 degrees, the binding block is already configured to secure them at the correct position, preventing case disengagement
Solution Approach 2:
The wire binding block acts as an intermediary component between the wires and the case. It mediates the interaction by clamping the bent wires and using stopping blocks to prevent both the binding block and wires from being pulled out, thus resolving the engagement reliability issue caused by wire bending
2Manufacturing precision
If wires of different lengths are pressed into the case to ensure consistent projecting lengths, then the wire endpoints align, but the wires form curve sections that push the case outward and may be pulled out unintentionally
Solution Approach 1:
The curve section of the bent wires, which initially causes harmful effects by pushing the case outward, is converted into a beneficial feature. The stopping blocks of the wire binding block are designed to engage with this curve section, transforming the outward force into a locking mechanism that prevents the binding block and wires from being pulled out
Solution Approach 2:
The wire binding block extracts the problematic curve section from the case interior by securing it externally. The binding block clamps the wires at their curve section and uses stopping blocks to anchor this section, removing the harmful pushing effect on the case while maintaining wire length consistency
3Reliability
If a wire binding block is used to clamp and fix the curve section of wires, then wire positioning is secured, but the structure becomes more complex
Solution Approach 1:
The wire binding block merges multiple functions into a single component: it clamps the curve section of the wires, positions them securely, and uses integrated stopping blocks to prevent pull-out. This consolidation achieves high wire fixation reliability without proportionally increasing structural complexity

AI summary
A fixing structure of a connector is disclosed. The connector includes an insert portion and multiple wires connected to the insert portion. The fixing structure includes a wire binding block, a lower shell and an upper shell disposed with multiple first engaging structures. The lower shell is disposed with multiple second engaging structures separately corresponding to the first engaging structures and connected with the upper shell to form a chamber for receiving the connector and form a wiring hole for being passed by the wires. The wires are extended from the insert portion toward the wiring hole to form a bend section and a curve section in the chamber. The wire binding block is fixed on the curve section of the wires and clamped by the upper shell and the lower shell through engagement of the first engaging structures and the second engaging structures.
