Push-In Jig Detection Structure for Connector Item Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional joint connectors face challenges in identifying different item numbers without enlarging the housing, as dedicated shapes are considered for identification, which can lead to increased size.
Innovation Solution
A different-item-number detection structure using a push-in jig with a detection portion that distinguishes between regular and irregular combinations by contacting an insulation wall, allowing for identification without altering the housing shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated shape is provided to the connector housing for identifying item numbers, then identification capability is improved, but the housing size is enlarged
Solution Approach 1:
The patent moves the identification function from the housing (spatial dimension) to the jig (operational dimension). The detection portion on the jig interacts with the insulation wall in a specific operational configuration, enabling item number identification without adding spatial features to the housing. This transforms a spatial identification problem into an operational detection problem.
Solution Approach 2:
The push-in jig serves as an intermediary tool that mediates between the operator and the connector housing. The detection portion on the jig indirectly detects item numbers by contacting or not contacting the insulation wall, allowing identification without direct observation or measurement of the housing itself.
2Measurement precision
If the connector housing is enlarged to accommodate identification features, then item number identification is enabled, but manufacturing cost increases
Solution Approach 1:
The push-in jig is designed to perform multiple functions: pushing busbars into the housing and detecting item numbers. The detection portion serves dual purposes by being positioned to both apply force during insertion and detect the insulation wall configuration. This multi-functionality eliminates the need for separate identification features, reducing manufacturing complexity and cost.
Solution Approach 2:
The insulation wall structure within the housing serves the dual purpose of electrical insulation and item number identification. The same structural element that provides functional insulation also provides the detection feature, eliminating the need for additional identification components and reducing overall manufacturing cost.
3Manufacturing precision
If a detection structure is added to identify housing types, then assembly accuracy is improved, but device complexity increases
Solution Approach 1:
The detection function is merged with the push-in operation. The detection portion is integrated into the jig body, and the same operational motion of pushing the busbar also performs the detection. This merging eliminates separate detection mechanisms and simplifies the overall system while maintaining assembly accuracy.
Solution Approach 2:
The patent uses the presence or absence of contact between the detection portion and insulation wall as a binary parameter change to indicate different item numbers. This simple parameter change (contact vs. no contact) provides clear identification without requiring complex detection electronics or multiple detection states.

AI summary
A different-item-number detection structure for detecting whether a combination of a connector and a push-in jig is regular, wherein the connector includes a plurality of busbars and a housing including a plurality of busbar accommodation rooms, the housing includes a housing main body formed and an insulation wall to partition an inside of the housing main body to insulate the busbars from each other, the push-in jig includes a jig main body, a plurality of push-in portions provided to protrude from the jig main body for pushing in the busbars, and a detection portion provided in the jig main body and configured to detect whether or not the housing is regular, when the push-in jig is pushed toward the housing, in a case in which the detection portion is not in/in contact with the insulation wall, it is detected that the housing and the push-in jig form a regular/irregular combination.
