Connector Shield Plate with Bent Portion for Bolt Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector connection structures face challenges in closing openings of casings while maintaining device storage performance, as the space opposite to the wall surface is often insufficient for tightening bolts, especially when other devices are arranged nearby.
Innovation Solution
A connector connection structure featuring a case with intersecting surfaces, a closing portion with a bent portion, and a fastening member inserted from a different direction, allowing the closing portion to deform and tightly adhere to the surface, ensuring the opening is closed while allowing easier access for fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closing member is fixed to the casing by a bolt inserted from the same direction as the connector terminal, then the opening can be closed to ensure shielding feature, but it becomes difficult to tighten the bolt when other devices are arranged nearby, reducing device storage performance
Solution Approach 1:
The patent applies dimensionality change by inserting the fastening member from a direction different from the connector terminal insertion direction. Specifically, the fastening member is inserted from the opposite side of the casing wall, while the connector terminal is inserted from the front side. This spatial separation in different directions resolves the conflict between achieving proper shielding closure and maintaining ease of tightening operation, as the fastening operation no longer interferes with connector insertion space and vice versa.
2Ease of operation
If a great space is reserved at the position opposite to the wall surface for performing tightening work, then the bolt can be tightened easily, but the device storage performance is reduced
Solution Approach 1:
The patent resolves this contradiction by changing the spatial dimension of the fastening operation. Instead of requiring lateral space adjacent to the wall surface for bolt tightening, the fastening member is inserted from the opposite side of the casing (through the wall thickness direction). This allows tightening operations to be performed without reserving additional lateral space, thereby maintaining optimal device storage performance while ensuring ease of fastening operation.
3Device complexity
If the closing member is fixed by a bolt inserted from the same direction as the connector terminal, then the structure is simplified, but the connector terminal and fastening member interfere with each other when space is tight
Solution Approach 1:
The patent addresses this contradiction by implementing fastening member insertion from a different direction (opposite side of the casing) compared to the connector terminal insertion direction (front side). This directional separation eliminates interference between the two components during installation and operation, enhancing space adaptability. While this adds slight structural complexity compared to same-direction insertion, it enables the system to function effectively in tight spaces where component interference would otherwise be unavoidable.

Function Achieved in This Case
This configuration enables effective closure of the opening while improving device storage performance by ensuring sufficient space for fastening, even in tight spaces, thereby enhancing the storage and shielding features.
Implementation Method 1
the first portion of the closing portion can be deformed so as to conform to the first surface positioned around the opening, thereby causing the first portion to tightly adhere to the first surface

AI summary
A connector connection structure includes: a case having a side surface and a top surface, respectively extending in directions crossing each other at a first angle, and an opening; a connector terminal portion inserted into the case from the opening; a shield plate closing the opening; a bolt fastening the case and the shield plate; and a terminal block arranged in the case and connected to the connector terminal portion. The shield plate has a first portion extending along the side surface and closing the opening, a second portion extending along the top surface, and a bent portion positioned between the first portion and the second portion and bent at a second angle being smaller than the first angle. The bolt fastens the case and the second portion of the shield plate.
