Electrical Terminal Bending Wings Notch Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical terminals in connectors are difficult to install and fix in small spaces due to their plate-shape configuration, which limits assembly efficiency and requires additional space between terminals.
Innovation Solution
The electrical terminal design includes bending wings with notches and a mounting portion with a fixing member, which assists in position orientation and secure fixation within the connector base, using guiding grooves and pin holes to prevent incorrect insertion and enhance alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plate-shape electrical terminals are used to increase contact area for large-current transmission, then electrical contact performance is improved, but installation difficulty increases and assembly time is extended
Solution Approach 1:
The electrical terminal is segmented into multiple functional parts: a plate-shaped terminal body for electrical contact, bending wings for positioning, notches for fixation, and a mounting portion for connection. This segmentation allows each part to perform its specific function efficiently, resolving the contradiction between maintaining large contact area and enabling easy installation.
Solution Approach 2:
The bending wings are pre-formed on the lateral edges of the terminal body, and notches are pre-provided on the bending wings. These preliminary structural features enable the terminal to be self-positioning and self-fixing during assembly, eliminating the need for complex installation procedures and reducing assembly time while maintaining reliable electrical contact.
2Reliability
If plate-shape electrical terminals are used to increase contact area, then electrical transmission capability is improved, but space requirements increase making installation in small spaces difficult
Solution Approach 1:
The bending wings extend laterally from the terminal body in a direction perpendicular to the main electrical contact surface. This dimensional extension allows the terminal to occupy minimal space in the primary plane while providing positioning and fixation functions through the laterally projecting wings, enabling dense arrangement of terminals in small spaces.
Solution Approach 2:
The notches are formed within the bending wings, creating a nested structure where the fixing feature is integrated into the positioning structure. This nesting allows the terminal to be fixed securely within the base without requiring additional space for separate fixing mechanisms, enabling compact terminal arrangement.
3Stability of the object's composition
If fixing holes are provided in the terminal body for fixation, then terminal fixation is enabled, but installation complexity increases
Solution Approach 1:
The bending wings with notches serve dual functions: they provide positioning during insertion and enable fixation when the wings bend to engage with the base structure. The terminal is self-positioning and self-fixing through its own structural features, eliminating the need for separate fixing holes and complex installation procedures.
Solution Approach 2:
The bending wings are designed to be flexible rather than rigid, allowing them to bend during insertion and then maintain a fixed position after installation. This dynamic characteristic enables simple insertion without pre-drilled holes, as the wings naturally engage with the base structure to provide secure fixation.

AI summary
An electrical terminal includes a terminal body and a mounting portion. The terminal body includes a front end, a rear end, and two lateral edges opposite to each other. The front end and the rear end are arranged opposite to each other, and the two lateral edges are connected to the front end and the rear end. The terminal body further includes one or more bending wings formed on one of the two lateral edges. The bending wing is provided with a notch, one side of the notch corresponding to the front end is closed. The mounting portion is extended from the rear end, and the mounting portion is provided with a fixing member. An electrical connector is also disclosed, which includes the electrical terminal provided with the notch to achieve the fixing operation of the electrical terminal.
