Electrical Connecting Device With Comb Element For Simultaneous Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of electrical connectors without an insulative body is time-consuming, especially with smaller terminals, which complicates manufacturing due to the difficulty in pick and place operations.
Innovation Solution
An electrical connecting device comprising a plurality of electrical connecting elements with a removable component, featuring a comb element and supporting elements that allow for simultaneous placement and soldering onto a printed circuit board, reducing assembly time and enabling free-standing support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If terminals are made smaller to reduce connector size, then the height and size of the electrical connector is reduced, but the difficulty of pick and place operation increases significantly
Solution Approach 1:
Multiple electrical connecting elements are merged into a single integrated component structure where individual terminals are connected through a common base portion, allowing them to be handled and placed as one unit rather than separate small components
Solution Approach 2:
The electrical connecting element is segmented into distinct functional parts (base portion, connecting portions, arm portion) that can be manufactured separately and then assembled, with the base portion serving as a handling feature during assembly
2Manufacturing precision
If terminals are soldered one after another by pick and place operation, then each terminal can be individually positioned, but the assembly process becomes time-consuming
Solution Approach 1:
Multiple electrical connecting elements are combined into a single integrated component that is placed and soldered as one unit, transforming multiple sequential operations into a single simultaneous operation while maintaining precise positioning through the integrated base structure
Solution Approach 2:
The electrical connecting elements are pre-assembled into an integrated component with proper positioning features before placement, allowing the entire assembly to be positioned and soldered in one operation rather than positioning each terminal separately

AI summary
An electrical connecting device includes an electrical connecting member including an electrical connecting element and a removable component connecting to the electrical connecting element. The electrical connecting element includes a base portion extending on a plane, two connecting portions formed on the base portion, and an arm portion extending between the two connection portions. The removable component includes a plurality of finger portions each connecting to one connecting portion of each adjacent electrical connecting element at a connection that is configured to be breakable. A supporting element respectively extend from the end portions of two outermost ones of the finger portions of the comb element and extend adjacent to the plane and beside the arm portions of the electrical connecting elements.
