Electrical Connector Base Positioning via Integrated Ribs and Trenches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in positioning terminal pins due to the lack of complex structures in plastic bases, leading to stress and assembly issues during insertion and detachment, which affects production yield and results in defective products.
Innovation Solution
A base with a combination of a body and a front cover featuring positioning members, such as protruding ribs and recessed trenches, that form a terminal insertion hole, allowing for precise alignment and secure positioning of terminal pins without additional fixing elements, simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an external fixing pin is inserted into the base to hold terminal pins, then terminal pin positioning is improved, but assembly complexity and difficulty increase
Solution Approach 1:
The patent merges the positioning function into the base structure itself by forming positioning protrusions directly on the inner wall of the through hole. This eliminates the need for separate external fixing pins, thereby maintaining precise terminal pin positioning while reducing assembly complexity and the number of components.
Solution Approach 2:
The patent extracts the positioning function from a separate external component (fixing pin) and integrates it directly into the base structure through positioning protrusions formed on the through hole inner wall. This reduces the number of parts and simplifies the assembly process while maintaining positioning effectiveness.
2Stability of the object's composition
If an external fixing pin is used to position terminal pins, then positioning stability is improved, but production yield decreases due to assembly failures
Solution Approach 1:
By integrating positioning protrusions directly into the base structure, the patent eliminates separate assembly steps for installing external fixing pins. This reduces assembly failures and improves production yield while maintaining stable terminal pin positioning through the built-in protrusion structures.
3Ease of manufacture
If a plastic base is used for the electrical connector, then manufacturing simplicity is improved, but positioning capability for terminal pins deteriorates
Solution Approach 1:
The patent applies local quality by creating positioning protrusions on the inner wall of the through hole in the plastic base. These localized structural features provide precise positioning capability at specific locations while maintaining the overall simplicity of plastic injection molding manufacturing for the base structure.

AI summary
A base of an electrical connector includes a body and a front cover. An installation trough is formed on a first side surface of the body. The body further includes one or more first through holes communicating the installation trough and a second side surface of the body. One or more first positioning members are disposed on an inner wall of the installation trough. The front cover includes a front surface, a rear surface, and one or more second through holes communicating the front and the rear surfaces. One or more second positioning members are disposed on an outer wall of the front cover for combining with the first positioning member. The front cover is embedded into the installation trough with the rear surface facing the body, such that the second positioning member combines with the first positioning member, and the second through hole communicates the first through hole.
