Semiconductor Device Terminal Attachment Member Inner Region Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional semiconductor devices have limited flexibility in attaching screw block and pin terminals, as they are typically fixed to the outer peripheral portion of the case member, restricting the degree of freedom in terminal positioning.
Innovation Solution
The semiconductor device incorporates a terminal attachment member with second terminal fixing portions that allow terminals to be attached to the inner region of the base plate, providing increased flexibility in terminal positioning without adding complexity to the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminals are fixed only on the outer peripheral portion of the case member, then the structure remains simple, but the degree of freedom in terminal positioning is limited
Solution Approach 1:
The patent extends terminal fixing functionality from the traditional outer peripheral portion (one-dimensional boundary) into the inner region of the base plate (two-dimensional area). The terminal attachment member spans from the outer peripheral portion inward, creating multiple fixing positions along its length, thereby adding spatial dimensionality to terminal positioning options.
Solution Approach 2:
The terminal attachment member acts as an intermediary component that bridges the case member and the terminals. It provides second terminal fixing portions in its inner region that can fix terminals without requiring direct modification of the case member structure, thus maintaining case member simplicity while enabling flexible terminal positioning.
2Ease of operation
If terminals are attached only on the outer peripheral portion, then the case member structure is simple, but terminal attachment flexibility is reduced
Solution Approach 1:
The terminal attachment functionality is segmented into two distinct portions: first terminal fixing portions on the outer peripheral portion of the case member, and second terminal fixing portions on the inner region of the base plate via the terminal attachment member. This segmentation allows terminals to be fixed at different locations depending on requirements, enhancing attachment flexibility.
Solution Approach 2:
The invention transitions from fixing terminals only at the peripheral boundary to fixing terminals across the inner area of the base plate. The terminal attachment member extends from the periphery inward, creating a gradient of fixing positions that expand the operational flexibility for terminal arrangement.

AI summary
On a case member of a semiconductor device, a screw block terminal or the like for connection to external equipment is attached. The screw block terminal or the like arranged on a region inside a base plate is attached to a terminal attachment member. Terminal attachment member has wall-like bodies, similar to wall-like bodies formed on a sidewall portion, formed along the direction of extension of terminal attachment member. On one end of terminal attachment member in the direction of extension, a side fitting portion is formed that corresponds to the wall-like body, and by fitting the side fitting portion to a space between sidewall portion and the wall-like body, terminal attachment member is fixed on case member. Thus, a semiconductor device is provided that allows high degree of freedom with simpler structure, as to the position of attaching a screw block terminal or a pin terminal to the case member.
