Hollow Shell Reinforcement for Electrical Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connector devices often experience separation of the protective casing and signal terminal housing during plugging or unplugging, leading to exposure of the communication cable and potential electrical contact failures.
Innovation Solution
A hollow shell is integrated into the protective casing with a second opening at the front end to receive the signal terminal housing, featuring a shield plate and lateral plates to enhance protection and prevent separation, ensuring the protective casing and signal terminal housing remain connected during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the protective body is configured to sleeve around the terminal body without additional reinforcement, then the device structure is simple and easy to manufacture, but the protective body is prone to separate from the terminal body during plugging or unplugging operations
Solution Approach 1:
The shell is nested within the protective casing, with the shell's outer surface fitting into the inner cavity of the protective casing. This nested structure provides reinforcement while maintaining a compact, integrated design that prevents separation during plugging or unplugging operations.
Solution Approach 2:
The device is divided into distinct components (protective casing, shell, signal terminal housing) that are separately manufactured but precisely fitted together. The shell acts as a reinforcing segment within the protective casing, creating a modular structure that enhances stability without excessive complexity.
2Strength
If the protective casing is designed without reinforcement structures, then the manufacturing process is simple and cost-effective, but the protective casing lacks sufficient strength and the signal terminal housing is prone to damage
Solution Approach 1:
The shell is nested within the protective casing to provide reinforcement. This approach strengthens the protective casing without requiring a complete redesign of the manufacturing process, as the shell can be inserted into the existing protective casing structure.
Solution Approach 2:
The device combines different components (protective casing and shell) to create a composite structure that enhances strength. The shell material complements the protective casing material, providing additional reinforcement where needed while maintaining ease of manufacture through standardized components.
3Reliability
If the protective casing and signal terminal housing are connected without additional structures, then the device structure is simple, but the communication cable is easily exposed and electrical contact failures occur during plugging or unplugging
Solution Approach 1:
The shell is nested within the protective casing to create a more secure connection structure. This nested configuration prevents the protective casing from separating from the signal terminal housing during plugging or unplugging operations, thereby protecting the communication cable and ensuring reliable electrical contact.
Solution Approach 2:
The shell is pre-positioned within the protective casing to establish a secure connection before the signal terminal housing is attached. This preliminary structural preparation ensures that the protective casing and signal terminal housing remain firmly connected during subsequent plugging or unplugging operations, preventing cable exposure and electrical contact failures.

AI summary
An electrical connector device of the present invention is characterized that a shell is disposed at a second opening of a front end of a protective casing of the electrical connector device. The shell is hollow, and a third opening is disposed at a front end of the shell and is used to receive a rear end of a signal terminal housing of the electrical connector device. A second round hole corresponding to a first round hole of a rear end of the protective casing is disposed at a rear end of the shell. As a result, the shell is configured to reinforce strength of the protective casing. A life of use of the electrical connector device is prolonged since the protective casing and the signal terminal housing of the electrical connector device are difficult to be separated when the signal terminal housing is plugged or unplugged.
