Contact Pin Connector with Integrated Filtering Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contact pin connectors used in automotive applications face challenges in achieving high transmission quality due to mechanical loads and interference suppression, particularly in compact designs where additional interference suppression on the wiring harness is often necessary.
Innovation Solution
The contact pin connector incorporates electrical components such as capacitors and ESD protection devices directly on the connector or printed circuit board, using reflow technology for soldering, which allows for improved signal filtering and suppression without the need for additional interference suppression on the wiring harness, and is designed with a housing made from temperature-resistant materials like liquid crystal polymer and semi-aromatic polyamides for robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional interference suppression components are added to the wiring harness, then signal transmission quality is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent integrates filtering and interference suppression electrical components directly onto the contact pin connector housing or printed circuit board, combining multiple functions (connection, filtering, suppression) into a single integrated unit. This eliminates the need for separate interference suppression components in the wiring harness, reducing overall device complexity while maintaining signal transmission quality.
Solution Approach 2:
The contact pin connector is designed to perform multiple functions simultaneously: electrical connection through contact pins, signal filtering through capacitors, and interference suppression through ESD protection devices. This multi-functional design replaces what would traditionally require separate components, reducing the number of parts needed in the system.
2Reliability
If electrical components are integrated directly on the connector, then transmission quality is improved and wiring harness suppression is reduced, but manufacturing complexity increases
Solution Approach 1:
The electrical components (capacitors, ESD protection devices) are pre-soldered onto the contact pin connector housing or printed circuit board during the connector manufacturing process. This preliminary action ensures that filtering and suppression functions are already integrated into the connector before installation, simplifying the overall assembly process and reducing manufacturing steps required after connector installation.
Solution Approach 2:
The manufacturing process combines the connector housing, contact pins, and electrical components into a single integrated assembly. By soldering the electrical components directly onto the connector housing or PCB during connector production, the patent eliminates separate assembly steps for installing filtering and suppression components, thereby simplifying the overall manufacturing process despite the integrated design.
3Volume of moving object
If compact connector design is implemented, then space requirements are reduced, but interference suppression capability is compromised
Solution Approach 1:
The patent integrates filtering capacitors and ESD protection devices directly onto the compact connector housing or printed circuit board, combining multiple functions (connection, filtering, suppression) into a single space-efficient unit. This integration maintains interference suppression capability while minimizing the overall space required, as the suppression functions are built into the connector itself rather than requiring separate components in the wiring harness.
Solution Approach 2:
The electrical components are strategically positioned at specific locations on the connector housing or PCB where they can most effectively filter and suppress interference for each contact pin. This localized placement ensures that each signal path receives appropriate filtering and suppression while maintaining a compact overall connector design.

AI summary
A contact pin connector (100; 101) has a housing (110, 130) and a plurality of contact pins (140) which are designed and arranged on the housing (110, 130) such that they protrude from the housing (110, 130) for contacting and soldering to a printed circuit board. At least some of the contact pins (140) are electrically coupled to corresponding electrical components (170) for filtering and/or suppressing electrical signals transmitted along the respective contact pins (140). These electrical components (170) are soldered onto a circuit board (160) of the contact pin connector (100; 101) using a reflow process, and the circuit board also electrically contacts the contact pins (140).
