Right-Angle Connector Fastener Structure for Compact Shielded Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors at the battery pack end require large installation spaces due to non-disassemblable metal bars, hinder miniaturization, and lack functions like waterproof sealing, electromagnetic shielding, and finger protection.
Innovation Solution
A fastener with an outer flange and screw rod for vertical fastening, a conductive sleeve, and an insulation end cap, combined with a connector design featuring an outer shielding shell and insulation inner housing, allowing for disassembly and assembly, thus reducing size while providing waterproof sealing, electromagnetic shielding, and finger protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal bars are bent 90 degrees as a single piece, then right angle electrical connections are achieved, but installation space increases and connector size becomes too large
Solution Approach 1:
The metal bar is divided into separate segments (first metal bar and second metal bar) that can be independently positioned and connected through the conductive sleeve, eliminating the need for a single large bent piece and reducing overall connector volume
Solution Approach 2:
The conductive sleeve is inserted into the conductive terminal, and the second metal bar passes through the conductive sleeve, creating a nested structure that compactly accommodates multiple components in a small space while achieving the right angle connection
2Reliability
If connectors include multiple functions (waterproof sealing, electromagnetic shielding, high-voltage interlocking, finger protection), then safety and functionality are improved, but device complexity increases
Solution Approach 1:
The conductive terminal is designed to simultaneously provide electrical connection, electromagnetic shielding through its conductive material, high-voltage interlocking through its structural configuration, and finger protection through the insulation end cap, allowing one component to fulfill multiple functions
Solution Approach 2:
Multiple protective and functional features (insulation end cap, conductive shielding, interlocking mechanisms) are merged into a single integrated connector assembly, reducing the number of separate components while maintaining all required functions

AI summary
The present invention discloses a fastener, an electrical connection module and a connector. The fastener (33) has an outer flange (33c) and a threaded hole (33a) located at one end, as well as a screw rod (33b) located at the other end; the screw rod (33b) of the fastener (33) is adapted to pass through a conductive sleeve (32) and be threaded with a conductive terminal (31), and the outer flange (33c) of the fastener (33) is adapted to axially rest on one end of the conductive sleeve (32), so that the fastener (33) can vertically fasten the conductive sleeve (32) to the conductive terminal (31); the threaded hole (33a) of the fastener (33) is suitable for threaded connection with a bolt, so that a mating terminal can be fastened to one end of the conductive sleeve (32) through the bolt. In the present invention, the fastener, the conductive sleeve, and the conductive terminal can be disassembled and assembled, thus requiring less installation space and reducing the size of the connector, achieving miniaturization of the connector. In addition, the connector of the present invention not only has a compact structure, but also has functions such as waterproof sealing, electromagnetic shielding, high-voltage interlocking, and finger protection.
