Joint Connector Ferrite Core Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joint connectors are complicated and costly due to strict dimension control requirements and are larger than general-purpose connectors due to wider intervals between needle shape terminal portions, which are not compatible with standard connectors.
Innovation Solution
A joint connector design featuring a terminal with a busbar and needle shape terminal portions, where a first ferrite core is placed at the base end and a second ferrite core at the intermediate portion, arranged alternately to reduce the interval between terminal portions to match general-purpose connectors, allowing for miniaturization and compatibility with standard connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single ferrite component with through holes is used, then the structure becomes complicated and dimension control becomes strict, but the noise reduction function is achieved
Solution Approach 1:
The ferrite component is divided into multiple separate ferrite beads that are串接 (series-connected) on the needle-shaped terminal portions. Instead of using a single complex ferrite component with through holes, the invention segments the noise reduction function into multiple simple ferrite beads, each sliding onto the terminal portions without requiring through holes or strict dimension control.
2Object-affected harmful factors
If a single ferrite component with through holes is used, then the noise reduction function is achieved, but the manufacturing cost increases

3Object-affected harmful factors
If wider interval between needle shape terminal portions is used, then the ferrite component can be fitted, but the joint connector becomes larger than general-purpose connector
Solution Approach 1:
The ferrite beads are arranged in a multi-dimensional configuration along the needle-shaped terminal portions, utilizing the length dimension of the terminals rather than requiring increased spacing between terminals. This allows the noise reduction function to be achieved without increasing the overall connector footprint, maintaining compatibility with general-purpose connector dimensions.
4Object-affected harmful factors
If wider interval between needle shape terminal portions is used, then the ferrite component can be fitted, but the compatibility with general-purpose connector is lost
Solution Approach 1:
The ferrite beads are arranged in a multi-dimensional configuration along the needle-shaped terminal portions, utilizing the length dimension of the terminals rather than requiring increased spacing between terminals. This allows the noise reduction function to be achieved without increasing the overall connector footprint, maintaining compatibility with general-purpose connector dimensions.

AI summary
For providing a joint connector which is miniaturized and general-purpose by designing an interval between needle shape terminal portions same as an interval between terminals of the general-purpose connector, the joint connector 1 includes a terminal 3 with a ferrite core 10, and a connector housing 2 receiving the terminal 3. The terminal 3 includes a busbar 28 and a plurality of needle shape terminal portions 29 extending from the busbar 28 at intervals along a direction of lengthwise of the busbar 28. The ferrite core 10 includes a first ferrite core 10a arranged at a base end 29a of the needle shape terminal portion 29 and a second ferrite core 10b arranged at an intermediate portion 29b of the needle shape terminal portion 29. The first ferrite core 10a and the second ferrite core 10b are arranged alternately at each of the plurality of needle shape terminal portions 29.
