Connector Holder Structure to Prevent PCB Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector structures for circuit boards lack securement mechanisms, leading to a risk of electrical connection loss due to detachment of the circuit board from the housing.
Innovation Solution
A connection structure that includes a holder with a circuit board restricting part to prevent the circuit board's separation and a connector restricting part to prevent the connector's separation from the board, utilizing a flange and projecting piece to ensure secure engagement and reliable electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the circuit board is not secured to the housing, then the structure is simpler and easier to manufacture, but the electrical connection may be lost due to detachment
Solution Approach 1:
The holder is divided into multiple functional parts: a body portion that supports the circuit board, a circuit board restricting part that prevents board detachment, and a connector restricting part that prevents connector separation. This segmentation allows each part to perform its specific function independently, securing the electrical connection while maintaining manufacturing simplicity.
Solution Approach 2:
The circuit board restricting part and connector restricting part are designed to engage with the circuit board and connector respectively, creating preliminary mechanical constraints that prevent detachment before any electrical connection failure can occur. This preliminary mechanical securing ensures reliability without requiring complex additional mechanisms.
2Reliability
If restricting parts are added to prevent detachment, then electrical connection stability improves, but the device complexity increases
Solution Approach 1:
The circuit board restricting part and connector restricting part are integrated into a single holder structure rather than being separate components. This merging reduces the overall number of parts and assembly steps while still providing both restriction functions, thereby improving connection stability without proportionally increasing device complexity.
Solution Approach 2:
The holder serves multiple functions: it supports the circuit board, restricts circuit board movement, restricts connector movement, and maintains electrical connection. By designing the holder as a multi-functional component, the patent avoids the need for separate structures for each function, thus improving reliability without excessive complexity increase.

AI summary
A connection structure for a connector to be connected to a connection part of a circuit board supported by a holder, wherein the connection part and the connector are detachably joined, and the holder is provided with: a circuit board restricting part configured to engage with the circuit board electrically connected to the connector to restrict movement of the circuit board in a direction separating from the connector; and a connector restricting part configured to engage with the connector electrically connected to the circuit board to restrict movement of the connector in a direction separating from the circuit board.
