Rotating Pin Header Connector for PCB Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic controllers with connectors integrated into one casing member restrict the opening direction of the connector to a vertical orientation, limiting the selection of connectors and making it difficult to set the opening direction along the electronic circuit board.
Innovation Solution
Incorporating a guiding projection and guiding portion on the pin header and casing member, allowing the pin header to turn and align with the housing, enabling the connector's opening direction to be set along the electronic circuit board, even when the housing is formed integrally with one casing member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the housing is formed integrally with one casing member and the electronic circuit board is sandwiched between the pair of casing members, then the connector structure is simplified and manufacturing is easier, but the opening direction of the connector is restricted to vertical direction only
Solution Approach 1:
The pin header is designed to be rotatable relative to the electronic circuit board through a turning mechanism. During assembly, the pin header rotates from an initial position to a final position where its opening direction aligns with the electronic circuit board plane. This dynamic adjustment capability allows the connector opening direction to be changed from vertical to horizontal, resolving the contradiction between simplified integrated structure and limited opening direction.
2Ease of manufacture
If the pin header is mounted in advance on the electronic circuit board, then the assembly process is simplified, but the pin header necessarily interferes with the cover when the electronic circuit board is assembled to the cover
Solution Approach 1:
The pin header is designed with rotational capability around a turning axis. During the assembly process, the pin header rotates dynamically to change its opening direction from vertical to horizontal, allowing it to pass through the cover without interference and then settle into its final position where the terminals extend horizontally. This dynamic movement resolves the spatial interference problem while maintaining the pre-mounted assembly advantage.
3Adaptability or versatility
If the opening direction of the connector is set to horizontal direction, then more connector selections are available, but the pin header necessarily projects from the outer shape of the electronic circuit board
Solution Approach 1:
The pin header utilizes the thickness direction of the electronic circuit board as a turning axis. By rotating the pin header 90 degrees around this axis, the opening direction changes from vertical to horizontal while the pin header remains contained within the outer shape boundaries of the electronic circuit board. The terminals extend horizontally in the plane of the circuit board without projecting beyond its outer轮廓, thus achieving both horizontal opening capability and compact外形.

AI summary
Provided is an electronic controller which enables an opening direction of a connector to be set along an electronic circuit board. The electronic controller includes first guiding projections (7a) and second guiding projections (7b) formed on a cover (2), and first guiding grooves (8a) to be brought into engagement with the first guiding projections (7a) and second guiding grooves (8b) to be brought into engagement with the second guiding projections (7b), which are formed on pin headers (4). The first guiding projections (7a) and the second guiding projections (7b) move respectively along the first guiding grooves (8a) and the second guiding grooves (8b). As a result, the pin headers (4) turn to be assembled to housings (14).
