Stacked Connector PCB Positioning Without Intermediate Spacer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors have a complex structure due to an intermediate component that occupies space between built-in circuit boards, making assembly cumbersome.
Innovation Solution
The electrical connector design incorporates a first housing with a first abutting post that partially passes through a first base portion to abut against a second base portion, eliminating the need for an intermediate component and allowing for a stacked arrangement of circuit boards, with tongue portions protruding into a mating space for connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an intermediate component is used to separate and fix the first built-in circuit board and the second built-in circuit board, then the circuit boards are fixed and separated, but the structure becomes complex and assembly becomes cumbersome
Solution Approach 1:
The patent removes the intermediate component from the connector structure, extracting the problematic element that caused structural complexity. The first and second built-in circuit boards are directly mounted on the first and second housings respectively, eliminating the need for the intermediate component while maintaining the fixing and separation function through the housing structures themselves.
Solution Approach 2:
The patent merges the fixing function with the housing structures. The first housing directly fixes the first built-in circuit board, and the second housing directly fixes the second built-in circuit board, combining the support and fixing functions into the main housing structures rather than requiring a separate intermediate component.
2Stability of the object's composition
If an intermediate component is used to separate the first built-in circuit board and the second built-in circuit board, then the circuit boards are separated, but the assembly process becomes cumbersome
Solution Approach 1:
The intermediate component is extracted from the design, simplifying the assembly process. The first built-in circuit board is assembled directly with the first housing and the second built-in circuit board is assembled directly with the second housing, eliminating the additional step of assembling with an intermediate component while maintaining proper separation.
3Stability of the object's composition
If an intermediate component occupies space between the first built-in circuit board and the second built-in circuit board, then the circuit boards are positioned, but the overall connector size increases
Solution Approach 1:
The intermediate component is removed, reducing the overall length of the connector in the direction extending from the first housing to the second housing. The circuit boards are positioned directly on their respective housings, eliminating the additional space occupied by the intermediate component while maintaining proper positioning through the housing structures.

AI summary
An electrical connector includes a housing, a first built-in circuit board and a second built-in circuit board. The housing includes a first housing and a second housing. The first housing includes a first abutting post. The first built-in circuit board includes a first base portion and a first tongue portion. The second built-in circuit board includes a second base portion and a second tongue portion. The first built-in circuit board and the second built-in circuit board are stacked. The first abutting protrusion at least partially passes through the first base portion along a second direction to abut against the second base portion.
