Innovation Solution
A connector design featuring a first housing with a wire terminal and a second housing with a board terminal, where the first connector is moved vertically and then horizontally to establish contact, utilizing a rotatable actuator for secure locking and simplified structure, reducing size and cost while ensuring reliable contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional wire-to-board connectors use shells attached to housings to improve electromagnetic shielding characteristics, then electromagnetic shielding is improved, but device complexity and size increase
Solution Approach 1:
The invention extracts and eliminates the shell component from the connector structure. Instead of using separate shells attached to housings for electromagnetic shielding, the patent achieves shielding through the housing structure itself and terminal arrangement, thereby simplifying the overall connector structure while maintaining electromagnetic shielding effectiveness
Solution Approach 2:
The invention merges the electromagnetic shielding function into the housing structure rather than requiring separate shell components. The housing is designed to provide both structural support and electromagnetic shielding, consolidating multiple functions into a single component and reducing overall complexity
2Reliability
If conventional connectors maintain reliable contact conditions for high-speed signals, then transmission reliability is improved, but structure becomes complex and costly
Solution Approach 1:
The invention implements preliminary positioning features in the housing structure that guide the wire connector into proper alignment before terminal contact is established. This preliminary action ensures reliable contact conditions are achieved automatically during the connection process, eliminating the need for complex adjustment mechanisms
Solution Approach 2:
The connector design enables self-alignment and self-contact through specially designed terminal geometries and housing features. The terminals are configured to automatically establish reliable contact when the connectors are mated, without requiring complex external positioning or adjustment mechanisms
3Ease of manufacture
If the contact part extends straight in the vertical direction, then manufacturing is simplified, but the transmission path becomes longer and signal transmission is degraded
Solution Approach 1:
The invention transitions the transmission path from a purely vertical arrangement to a three-dimensional crank-shaped configuration. The terminal contact parts are designed to extend in multiple directions (vertical and horizontal segments), creating a folded transmission path that reduces the effective signal distance while maintaining manufacturability through standard terminal fabrication processes
4Reliability
If a two-step fitting process (vertical then horizontal movement) is used, then reliable contact is ensured, but operation becomes more complex
Solution Approach 1:
The invention incorporates flexible or resilient terminal components that can dynamically adapt during the two-step fitting process. The terminals are designed to flex or deform elastically during vertical engagement and then lock into place during horizontal engagement, making the two-step process intuitive and reliable without requiring complex manual manipulation

AI summary
A connector includes a first connector including a first housing, a wire held by the first housing, and a first terminal held by the first housing, including the main body part connected to a conductive wire of the wire and a contact part extending in a first direction; and a second connector including a second housing and a second terminal held by the second housing, including a contact part extending in the first direction, which is mounted on the surface of the circuit board, where the first connector is moved in the first direction with respect to the second connector, and then moved in a second direction orthogonal to the first direction with respect to the second connector to be fitted to the second connector, and the contact part of the first terminal is brought into contact with the contact part of the second terminal, when the first connector is moved in the second direction with respect to the second connector.
