Electrical Connector Terminal Module Assembly Without Elastic Arm Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges with easy assembly due to interference between elastic arms and the insulating body, leading to deformation and assembly complexity.
Innovation Solution
The electrical connector design includes an insulating body with distinct receiving spaces and mating ports, allowing terminal modules to be installed through specific openings, reducing interference and facilitating assembly by aligning with the force direction of contact points, thus maintaining elastic arm reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic arms are assembled through elastic deformation to mate with the insulating body, then the terminal module can be securely installed, but the elastic arms are prone to deformation and failure due to interference during assembly
Solution Approach 1:
Instead of inserting terminal modules through mating ports from the front, the patent opens the insulating body from the rear to allow terminal modules to be installed from the back. This inversion of the assembly direction eliminates interference between elastic arms and the insulating body during assembly, preventing deformation while maintaining secure installation through the same elastic deformation mechanism
2Reliability
If elastic arms are designed to interfere with the insulating body during installation, then secure mating is achieved, but assembly complexity increases and time is consumed
Solution Approach 1:
The patent inverts the assembly approach by opening the insulating body from the rear and installing terminal modules from the back. This eliminates interference-based assembly complexity while maintaining secure mating through proper elastic arm engagement, significantly reducing assembly time without compromising reliability
3Device complexity
If terminal modules are installed through mating ports, then the connector structure is compact, but the elastic arms interfere with the insulating body causing deformation risk
Solution Approach 1:
The patent maintains the compact connector structure by keeping the overall insulating body design intact, but inverts the installation approach by opening from the rear and installing terminal modules from the back. This resolves the reliability issue by eliminating interference during assembly while preserving the compact form factor through the same structural design

AI summary
An electrical connector includes an insulating body and a first terminal module. The insulating body includes a first receiving space, a first mating port and a second mating port. The first mating port is configured to receive a first mating module. The second mating portion is configured to receive a second mating module. The insulating body includes a top wall portion. The top wall portion has a first opening communicating with the first receiving space. The first terminal module is installed into the first receiving space through the first opening. An opening direction of the first opening is different from opening directions of the first mating port and the second mating port. As a result, the electrical connector has high structural reliability and is easy to assemble.
