Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing board mount connectors require complex bending processes to achieve offset contact positions, which complicates manufacturing and reduces productivity due to the need for multiple bending steps.
Innovation Solution
A board mount connector design featuring a terminal with a first contact portion and a second contact portion offset from each other, where the second contact portion is bent around the axis of the first contact portion, allowing for simplified manufacturing and improved productivity by reducing the number of bending steps required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple bending processing steps are performed to create offset contact positions, then the connector can be mounted on circuit boards with offset contacts, but the manufacturing complexity and processing time increase
Solution Approach 1:
The terminal is divided into multiple functional portions: a first terminal portion with a first contact portion for mating with the counterpart terminal, a press-fitting portion for insertion into the housing, and a second terminal portion with a second contact portion for connection to the circuit board. This segmentation allows each portion to be optimized independently and simplifies the overall manufacturing process by enabling single-step bending to achieve the required offset configuration.
Solution Approach 2:
The invention introduces an offset configuration in the thickness direction of the circuit board, positioning the first contact portion and second contact portion at different heights. This dimensional approach allows the terminal to accommodate offset contacts on the circuit board while maintaining a simplified single-bending manufacturing process, rather than requiring multiple bending steps in the same plane.
2Adaptability or versatility
If multiple bending processing steps are performed on the terminal, then the offset contact positions can be achieved, but the productivity of terminal manufacturing decreases
Solution Approach 1:
The terminal is designed with pre-defined bending positions and geometries that can be formed in a single bending processing step. The first terminal portion, press-fitting portion, and second terminal portion are configured such that the offset relationship between contact portions is established through one bending operation rather than multiple sequential operations, thereby improving manufacturing productivity.
3Adaptability or versatility
If the terminal is designed with offset contact portions for circuit board mounting, then the connector can be mounted on circuit boards, but the manufacturing process becomes more complex
Solution Approach 1:
The terminal structure is segmented into distinct functional portions with clear boundaries: the first terminal portion for counterpart terminal connection, the press-fitting portion for housing insertion, and the second terminal portion for circuit board connection. This segmentation simplifies the manufacturing process by allowing each portion to be formed and positioned independently through a single bending operation, making the overall manufacturing easier despite the offset configuration requirement.

AI summary
A board mount connector includes: a housing having a press-fitting hole; and a terminal press-fitted into the press-fitting hole. The terminal includes: a first terminal portion including a first contact portion contacting and conductively connected to the counterpart terminal when the first contact portion is connected to the counterpart terminal, and a press-fitting portion that is press-fitted into the press-fitting hole; and a second terminal portion including a bent portion extending from the first terminal portion and bent around a bending axis along an axis line of the first terminal portion, and a second contact portion located at a position offset from the first contact portion in an intersecting direction intersecting the axis line of the first terminal portion and conductively connected to the conductor pattern when the boar mount connector is mounted on the circuit board.
