Ground Joint Connector Structure to Block Water Stop Material Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ground joint connectors, the application of a water stop material to the support plate portion of a connection member can cause it to flow into and adhere to the tab portions, increasing resistance values.
Innovation Solution
The connector design includes a bent structure in the tab portions, with a first base portion connected to the support plate and a second base portion folded back to overlap, forming a bent portion at the root, which prevents the water stop material from flowing into and adhering to the tab portions during application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water stop material is applied to the support plate portion of the connection member, then water stopping is improved, but the water stop material flows into and adheres to the tab portion, increasing resistance value
Solution Approach 1:
The base portion is divided into a first base portion and a second base portion that are folded back to overlap, creating a physical barrier that segments the flow path of the water stop material and prevents it from reaching the tab portions
Solution Approach 2:
The overlapping base portions act as an intermediary barrier between the water stop material application area and the tab portions, intercepting the water stop material before it can flow into and adhere to the tab portions

AI summary
A connector includes a connection member, and a housing in which a part of the connection member is insert molded. The connection member has a fixing plate portion, a support plate portion raised from the fixing plate portion, and a base portion connected continuously to the support plate portion and in which a plurality of tab portions are formed. The base portion has a first base portion connected continuously to the end portion of the support plate portion, and a second base portion formed on the side portion of the first base portion and folded back. The tab portion is connected continuously to the end portion of the second base portion and formed to be bent with respect to the second base portion, a bent portion is formed at the root portion of the tab portion, and a water stop material application portion is formed in the support plate portion.
