Adjustable Electrical Connector for Varying PCB Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with fixed latch spacing are unable to securely attach to circuit boards of varying thickness, leading to potential damage from improper force application and increased manufacturing costs for custom molds.
Innovation Solution
An electrical connection device featuring a limiting element with an inclined abutting-retaining face and a positioning mechanism allowing for adjustable placement in the front-rear direction, ensuring secure attachment to circuit boards of different thicknesses through a receiving groove and one-way latching teeth mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed spacing distance between the latch element and the insulative body is used, then the electrical connection is reliable for a specified circuit board thickness, but it cannot accommodate circuit boards with different thickness specifications
Solution Approach 1:
The latch element is designed to be movable relative to the insulative body along the clamping direction, transitioning between a first position for clamping the circuit board and a second position for releasing it. This dynamic adjustment capability allows the connector to adapt to different circuit board thicknesses while maintaining reliable electrical connection through the movable latch mechanism that can be positioned appropriately for each thickness variation
2Adaptability or versatility
If the latch element position is adjusted for different circuit board thicknesses, then adaptability is improved, but the structure becomes more complex
Solution Approach 1:
The limiting element is integrated into the insulative body as a unified structure, where the limiting element and insulative body work together to guide and limit the movement of the latch element. This merging of components provides the positioning function without requiring separate complex positioning mechanisms, thus achieving adaptability while controlling structural complexity
3Manufacturing precision
If custom molds are designed for different thickness specifications, then manufacturing precision is improved, but manufacturing cost increases
Solution Approach 1:
The connector is designed with a universal structure that can accommodate multiple circuit board thickness specifications through the adjustable latch element mechanism. Instead of requiring custom molds for each thickness, the same mold produces a universal connector that can be adjusted to work with different thicknesses, thereby reducing manufacturing costs while maintaining the necessary precision through the positioning mechanism

AI summary
An electrical connection device comprises an electrical connector, a receiving portion, and a limiting element. The electrical connector comprises a housing, a plurality of terminals supported by the housing, and a mounting face positioned at a bottom side thereof. The receiving portion is provided to the bottom side of the electrical connector and positioned in front of the mounting face and has a receiving groove extending in a front-rear direction. The limiting element is provided through the receiving groove and positioned in the receiving portion and has an abutting-retaining face inclined to the ground and facing the mounting face. When the electrical connection device is mounted to a circuit board, the mounting face is mounted to an upper surface of a circuit board, and the abutting-retaining face abuts against a front edge of a lower surface of the circuit board.
