Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connector assembly process is hindered by the difficulty in operating and correctly aligning small fixing pins, leading to failed directional matching and rework during the assembly of electrical terminals.
Innovation Solution
A base for the electrical connector featuring a fixing pin with latches and a stopping element, along with a base body having installation troughs and a pin hole, allows for simple and secure insertion of the fixing pin, ensuring correct alignment and fixation through a stepped segment and stopper block mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If small fixing pins are used to fix electrical terminals, then the assembly process becomes more compact, but the difficulty of operating the fixing pin increases and directional matching becomes unreliable
Solution Approach 1:
The fixing pin is segmented into multiple functional parts: a pin body for insertion, latches for engagement with stopper blocks, and a stopping element for positioning. This segmentation allows each part to perform its specific function effectively, resolving the contradiction between small size and ease of operation.
Solution Approach 2:
The latches act as intermediary elements between the fixing pin and the stopper blocks. They provide a mechanical interface that ensures reliable engagement and directional matching, making the small fixing pin easy to operate and position correctly during assembly.
2Volume of moving object
If small fixing pins are used to fix electrical terminals, then the overall connector size is reduced, but the reliability of directional matching decreases leading to reworks
Solution Approach 1:
The latches are positioned asymmetrically on the pin body at specific locations that correspond to the stopper blocks in the pin hole. This asymmetric design ensures correct directional matching during insertion, preventing misalignment and reworks while maintaining a compact fixing pin size.
Solution Approach 2:
The latches are pre-positioned on the pin body during manufacturing to align with the stopper blocks. This preliminary positioning ensures that when the fixing pin is inserted, the directional matching occurs automatically without requiring precise manual alignment, thereby improving reliability.
3Reliability
If traditional fixing methods are used, then the electrical terminals can be fixed, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The fixing pin combines multiple fixation functions into a single component: insertion through the pin hole, engagement with stopper blocks via latches, and positioning via the stopping element. This merging of functions into one integrated component simplifies the assembly process and increases productivity while maintaining reliable fixation.
Solution Approach 2:
The latches are designed to be elastic or flexible, allowing them to deform during insertion and then snap into engagement with the stopper blocks. This dynamic behavior enables quick, tool-free assembly while ensuring secure fixation of the electrical terminal.

AI summary
A base of an electrical connector includes a fixing pin and a base body. The fixing pin includes a pin body, a stopping element and one or more latches. The pin body includes a lower end and an upper end, the stopping element is disposed at the upper end, and the latch is disposed on the pin body in a protruding manner. One or more installation troughs are formed on a rear surface of the base body and the installation trough is in communication with a front surface of the base body through an insertion hole. The base body further includes a pin hole formed on an outer peripheral surface of the base body, and the pin hole is intersected with and in communication with the installation trough. The latch is adapted to be engaged with a stopper block formed on an inner wall of the pin hole.
