RJ-45 Connector Terminal Supporting Portion Misplugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RJ-45 electrical connectors face issues with misplugging, particularly when an RJ-11 plug is inserted, causing deformation of contact terminals and potential interconnection failure, and existing solutions increase production costs by adding separate position limiting members.
Innovation Solution
An RJ-45 electrical connector design featuring terminals with a built-in stop structure, including a supporting portion that extends from the terminal to prevent excessive downward deviation of the contact portion, reducing the need for additional components and lowering production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate position limiting member is provided below the contact portion to prevent excessive deviation, then the contact terminal deformation is prevented, but the components of the electrical connector are increased and production costs increase
Solution Approach 1:
The patent merges the position limiting function into the terminal structure itself by providing a supporting portion that extends from the insulating body to support the contact portion. This eliminates the need for separate position limiting members while maintaining the function of preventing excessive deviation and deformation of contact terminals.
Solution Approach 2:
The terminal structure serves itself by incorporating the supporting portion directly into the terminal design. The supporting portion automatically prevents excessive deviation of the contact portion without requiring external components, making the system self-sufficient and reducing overall component count.
2Reliability
If a separate position limiting member is provided below the contact portion, then the contact portion excessive deviation is blocked, but the production costs of the electrical connector are increased
Solution Approach 1:
The position limiting function is merged into the terminal structure through the supporting portion that extends from the insulating body. This integration reduces the total number of components that need to be manufactured and assembled, thereby lowering production costs while maintaining effective position control of the contact portion.
Solution Approach 2:
The supporting portion serves multiple functions: it provides mechanical support for the contact portion, prevents excessive deviation, and integrates with the insulating body structure. This multi-functionality eliminates the need for dedicated position limiting members, reducing manufacturing complexity and cost.

AI summary
An electrical connector includes an insulating body provided with an accommodating cavity for insertion of a mating connector; and a plurality of terminals retained in the insulating body. At least one of the terminals has a retaining portion, an extending portion extending forward from the retaining portion, a contact portion bending upward from a front end of the extending portion and obliquely extending backward into the accommodating cavity, and a supporting portion bending upward and extending from one side of the extending portion. The supporting portion is located below the contact portion. When a non-matching mating connector is inserted into the accommodating cavity, the contact portion abuts the supporting portion, and the supporting portion is configured to block the contact portion from excessive downward deviation.
