Connector Shield Grounding via Integrated Bus Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection of shield members to grounding terminals in shield attached flat cables is complex and time-consuming, requiring additional steps beyond connecting signal lines, increasing man-hours and complicating the assembly process.
Innovation Solution
A connector design featuring a bus bar and press-connecting blades integrated into a housing with a cover that simultaneously connects signal lines and shield members by exposing the shield member to the bus bar, reducing the need for separate grounding connections and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shield member is connected to the connector side grounding terminal using traditional methods, then the grounding connection is established, but the assembly process becomes complicated and requires additional steps beyond connecting signal lines
Solution Approach 1:
The patent merges the grounding connection function into the connector housing structure itself by providing a grounding terminal that is integrated with the housing and a grounding plate that contacts the shield member during the same insertion operation as signal line connection. This eliminates the need for separate grounding connection steps while ensuring reliable grounding.
Solution Approach 2:
The connector housing is designed to perform multiple functions simultaneously: it houses the signal terminals, provides the grounding terminal, and structures the grounding plate to contact the shield member. This multi-functionality allows both signal and grounding connections to be established through a single insertion operation, simplifying the assembly process.
2Reliability
If the shield member is connected to the connector side grounding terminal using traditional methods, then the grounding connection is established, but the man-hours required for connection increase
Solution Approach 1:
The grounding terminal and grounding plate are pre-integrated into the connector housing structure before assembly. This preliminary configuration ensures that when the plug connector is inserted into the socket connector, the grounding connection is automatically established simultaneously with the signal line connections, eliminating the need for additional manual grounding connection steps and reducing assembly time.
3Reliability
If a drain line is used to connect the shield member to the grounding terminal, then the grounding connection is established, but the constitution becomes complicated
Solution Approach 1:
The patent extracts the grounding connection function from the cable structure (removing the need for a dedicated drain line within the flat cable) and relocates it to the connector structure. The grounding plate in the socket connector directly contacts the shield member, establishing the grounding path externally without requiring internal drain line configuration within the cable, thereby simplifying the cable structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design significantly reduces the man-hours required for connection and simplifies the assembly by allowing a single operation to establish both signal and shield connections, preventing unnecessary external forces on the press-connecting parts and enhancing the structural integrity of the connection.
Implementation Method 1
a pressing force which makes the press-connecting blades that penetrate the insulators to be press-connected to the signal lines
Implementation Method 2
makes the shield member that is exposed from the shield attached flat cable contact the bus bar

AI summary
A connector housing, terminals which have press-connecting blades that are exposed from the back end surface of the connector housing, a bus bar plate which is mounted to the back end surface of the connector housing, and a cover which is mounted by a pressing force which makes the press-connecting blades that penetrate insulators to be press-connected to signal lines of a shield attached flat cable, and makes a shield member contact the bus bar, and which holds and fixes an electric wire sheath attached part between the cover and the connector housing are included.
