Solution Overview
Problem
Existing multipolar connectors face issues with deformation and positional displacement of pin-shaped terminals due to external forces, leading to connectivity problems when connecting circuit boards in electronic systems like electric power steering apparatuses.
Innovation Solution
A multipolar connector design featuring protection sections that extend from the hold member to cover and protect pin-shaped terminals, preventing deformation and positional displacement by absorbing external forces, ensuring stable insertion into through holes on circuit boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If pin-shaped terminals are made thin to reduce size, then the connector becomes more compact, but the terminals become prone to deformation and positional displacement under external forces
Solution Approach 1:
The patent applies beforehand cushioning by providing protection sections that extend from the hold member to cover the pin-shaped terminals before external forces are applied. These protection sections act as pre-positioned cushioning structures that absorb and distribute external forces, preventing deformation and positional displacement of the thin terminals while maintaining the compact connector design
2Reliability
If protection sections are added to protect pin-shaped terminals, then terminal stability improves, but device complexity increases
Solution Approach 1:
The patent merges the protection sections with the hold member into a single integrated structure. The protection sections extend from the hold member as a unified component, combining the functions of terminal positioning and terminal protection in one structure, thereby improving reliability without proportionally increasing device complexity

AI summary
A multipolar connector is provided. It is possible to prevent deformation of a particular pin-shaped terminal of plural pin-shaped terminals arranged in a line in a direction perpendicular to a connection direction of the multipolar connector, and also possible to prevent positional displacements of the particular pin-shaped terminal and other pin-shaped terminals. The multipolar connector (101) includes plural pin-shaped terminals (110) arranged in a line in a direction (arrow X direction) perpendicular to a connection direction (arrow Y direction) of the multipolar connector to extend in the connection direction, and a hold member (120) configured to extend in the direction perpendicular to the connection direction and hold the plural pin-shaped terminals (110) at a predefined pitch. A protection section (121) to protect a particular pin-shaped terminal (110) of the plural pin-shaped terminals (110) is provided at a part of the hold member (120) to extend from the hold member (120) to protrude in the connection direction of the particular pin-shaped terminal (110) to be protected and cover around the particular pin-shaped terminal (110).
