Single-Board Connector Terminal for Vibration-Stable Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage connectors with complex terminal structures face high production costs and manufacturing difficulties, and suffer from poor electrical contact due to vibration-induced changes in the gap between terminal boards.
Innovation Solution
A terminal design featuring a single terminal board with a locking member and elastic contact member, which simplifies the structure, reduces costs, and maintains reliable electrical contact even in vibration environments through the use of integral stamped parts and elastic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal body with two terminal boards is used, then the locking function is achieved, but the structure becomes complex and production cost increases
Solution Approach 1:
The patent combines two terminal boards into a single terminal board structure. The locking member is integrated directly onto the single terminal board, eliminating the need for a separate second terminal board while maintaining the locking function through the cooperative interaction between the locking member's locking block and the mating terminal's locking groove.
Solution Approach 2:
The single terminal board is designed to perform multiple functions: it provides the electrical connection function through the elastic contact member and the locking function through the integrated locking member. This multi-functional design replaces the need for separate terminal boards that would otherwise be required for these distinct functions.
2Reliability
If a terminal body with two terminal boards is used, then the locking function is achieved, but manufacturing difficulty increases
Solution Approach 1:
By merging the locking member and elastic contact member onto a single terminal board, the patent reduces the number of separate components that need to be manufactured and assembled. This integration simplifies the manufacturing process while ensuring the locking function is maintained through the designed interaction between components.

AI summary
The present invention discloses a terminal, a connector and a connector assembly. The terminal comprises of: a single terminal board (1) having a top surface (la) and a bottom surface (lb) opposite to each other in its thickness direction (Z); a locking member (2) fixed to the terminal board (1) and comprising a top plate (21) located above the top surface (la) of the terminal board (1); and an elastic contact member (3) which is installed on the top surface (la) of the terminal board (1) and faces the top plate (21) of the locking member (2). The elastic contact member (3) is used for electrical contact with a mating terminal (21) inserted between the elastic contact member (3) and the locking member (2) to achieve electrical connection between the terminal and the mating terminal. In the present invention, the terminal body of the terminal only includes a single terminal board, thus simplifying the structure of the terminal, reducing production cost and manufacturing difficulty. Moreover, the terminal of the present invention can also make reliable electrical contact with the mating terminal in vibration environments.
