Plug Connector Housing With PCB Receiving Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connectors, particularly plug and receptacle connectors, face issues such as damage during transportation due to the lack of securement of printed circuit boards and unfavorable structures that affect manufacturing and signal transmission reliability.
Innovation Solution
The connectors are designed with a receiving space between the upper and lower housings to secure the printed circuit board, and the receptacle connector's structure is improved with features like partially outwardly bent side walls, inlaid terminals, and shielding plates to enhance connection reliability and signal stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the printed circuit board is not secured to the housing, then the connector structure is simpler and easier to manufacture, but the printed circuit board may collide with the housing during transportation and cause damage
Solution Approach 1:
The housing is divided into an upper housing and a lower housing that can be assembled together to form a receiving space. This segmentation allows the printed circuit board to be securely positioned between the two housing parts through simple assembly operations, resolving the contradiction between ease of manufacture and reliability by creating a secure mounting structure without complex manufacturing processes.
Solution Approach 2:
The printed circuit board is nested within the receiving space formed by the upper and lower housings. This nesting arrangement naturally secures the printed circuit board in place during transportation while maintaining a simple overall structure that is easy to manufacture, as the housing parts themselves provide the securing function rather than requiring additional complex fastening mechanisms.
2Ease of manufacture
If the receptacle connector uses traditional structure, then the manufacturing process is simpler, but the connection reliability and signal transmission stability are insufficient
Solution Approach 1:
The receptacle connector incorporates a shielding plate at specific locations within the housing to improve signal transmission stability and connection reliability. This local quality enhancement adds shielding functionality only where needed for signal integrity, rather than requiring complete restructuring of the entire connector, thus maintaining relative manufacturing simplicity while achieving improved reliability.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical support, forms the receiving space for the printed circuit board, and when combined with the shielding plate, provides electromagnetic shielding. This multi-functionality allows the connector to achieve improved connection reliability and signal stability without proportionally increasing manufacturing complexity, as the same structural elements perform multiple roles.

AI summary
Disclosed are a plug connector component, a receptacle connector component, and a connector assembly. The plug connector comprises: an inserting portion; a printed circuit board, one portion of which is coupled to the inserting portion; an upper housing; and a lower housing, on which the upper housing is jointed, a receiving space for receiving the printed circuit board being formed between the upper housing and the lower housing, a side wall of the lower housing being partially outwardly bent to form a receiving groove on the side wall of the lower housing, a side of the printed circuit board being received in the receiving groove, the inserting portion being secured at a front end of the upper housing and the lower housing. The receptacle connector comprises a second metal shell having a joint chamber and a first module and a second module that are secured in the second metal shell, wherein: a first terminal is inlaid and insert molding in the first module; a second terminal is inlaid and insert molding in the second module, a contact portion of the first terminal overlapping a contact portion of the second terminal in a height direction perpendicular to an insertion direction; and a shielding plate is further inlaid and insert molding in the second module.
