Connection Terminal With Tapered Guide Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection terminals face challenges in insertion workability due to the potential for contact members and male connection bodies to abut during insertion, reducing efficiency and ease of use.
Innovation Solution
A connection terminal design featuring a female connection body with bulging bodies and a contact member that guides the male and contact members during insertion, utilizing tapered guide portions to facilitate smooth insertion and improve workability, with the bulging bodies sandwiching the male connection body for secure electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact portion bulges from the inner circumferential surface of the female connection body, then electrical connection is achieved by sandwiching the male connection body, but insertion workability deteriorates due to abutment between the contact member and male connection body
Solution Approach 1:
The internal space is divided into two distinct regions: a first region containing the contact member for electrical connection, and a second region containing the bulging bodies for guiding and securing the male connection body. This spatial segmentation allows each component to perform its function without interference, resolving the contradiction between reliable electrical connection and ease of insertion.
Solution Approach 2:
The bulging bodies act as intermediary elements that guide the male connection body during insertion and position it correctly before the contact member engages. This intermediary guidance mechanism prevents direct abutment between the contact member and male connection body, improving insertion workability while maintaining reliable electrical connection.
2Ease of manufacture
If the contact member and male connection body are inserted from the opening of the female connection body, then assembly is simplified, but abutment occurs during insertion reducing workability
Solution Approach 1:
The internal space is segmented into a first region for the contact member and a second region for the bulging bodies, allowing both components to be inserted from the same opening without interfering with each other during the insertion process.
Solution Approach 2:
The bulging bodies perform preliminary guiding action during insertion, positioning the male connection body correctly before the contact member engages. This preliminary guidance prevents abutment and facilitates smooth insertion of both components.

AI summary
A connection terminal includes a conductive terminal main body having a female connection body, and a contact member arranged to oppose an inner circumferential surface of the female connection body in one region of an internal space. A first bulging body and a second bulging body protruding from the inner circumferential surface and electrically connected to a male connection body by sandwiching the male connection body with the contact member are provided in the other region of the internal space. The second bulging body has a first guide portion guiding the male connection body while sliding the male connection body, and a second guide portion guiding the contact member while sliding the contact member. Each of the first and second guide portions is formed in a tapered shape.
