Electrical Connector Single Rear Plug Terminal Pin Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connecting apparatuses require two rear plugs to fix three rows of conductive terminals, complicating the assembly process due to the need for highly concentrated holes for long and thin terminals.
Innovation Solution
An electrical connecting apparatus with an insulating body featuring step portions arranged in groups and a rear plug with a warped surface, allowing a single rear plug to fix three rows of terminal pins by positioning them between the step portions and the warped surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two rear plugs are used to fix three rows of terminal pins, then all terminal pins can be secured, but the device complexity and assembly process become complicated
Solution Approach 1:
The patent combines the functions of two separate rear plugs into a single integrated rear plug structure. This single rear plug includes a body with multiple fixing portions that can simultaneously secure three rows of terminal pins, eliminating the need for two separate plugs and simplifying the overall device structure while maintaining the capability to fix all terminal pins reliably
Solution Approach 2:
The single rear plug is designed with multi-functional capabilities to perform the work of two traditional rear plugs. It includes multiple fixing portions (first fixing portion for first row, second fixing portion for second row, third fixing portion for third row) that can accommodate and secure terminal pins from three different rows simultaneously, making it a universal fixing component
2Device complexity
If holes are highly concentrated on one rear plug to accommodate three rows of terminal pins, then one rear plug can fix all terminals, but the manufacturing precision requirement increases
Solution Approach 1:
The single rear plug is segmented into multiple distinct fixing portions, each dedicated to a specific row of terminal pins. The first fixing portion fixes the first row, the second fixing portion fixes the second row, and the third fixing portion fixes the third row. This segmentation distributes the fixing functions across different regions of the rear plug body, reducing the need for highly concentrated holes and thereby lowering manufacturing precision requirements
Solution Approach 2:
The patent utilizes the spatial dimension by arranging fixing portions in different locations on the rear plug body corresponding to different rows of terminal pins. Instead of concentrating all fixing features in one area, the design spreads them out across the rear plug structure, using dimensional distribution to reduce precision demands while maintaining effective fixing capability

AI summary
An electrical connecting apparatus of the invention comprise an insulating body, a rear plug, and a plurality of conductive terminals. The insulating body comprises at least one first inserting portion, and a plurality of step portions being disposed at a back side of the insulating body. The step portions are arranged in the front and rear and divided into at least three groups. The rear plug, installed onto the back side of the insulating body, has a warped surface on a front side thereof. The first conductive terminals are correspondingly accommodated in the first inserting portion. Each of the first conductive terminals respectively comprises a mating portion accommodated in the first inserting portion and comprises a terminal pin extended and bent downward from the mating portion to the back side of the insulating body. The terminal pins are correspondingly disposed between one of the step portions and the warped surface.
