Standing Electrical Connector Positioning on Circuit Board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional standing-type electrical receptacle connectors are prone to detachment from circuit boards under impact forces due to inadequate positioning.
Innovation Solution
The design incorporates a metallic shell with an insulated housing and an outer shell featuring extending sheets and positioning portions that securely attach to the circuit board, enhancing stability and structural strength through soldering and optional locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector is positioned only by soldering terminals to the circuit board, then the manufacturing process is simple, but the connector becomes easily detached under impact force
Solution Approach 1:
The connector is divided into separate functional components: the insulated housing containing terminals, the metallic shell providing structural support, and the outer shell with positioning portions. This segmentation allows each part to perform its specific function - the positioning portions engage with the circuit board to prevent detachment, while terminals handle electrical connection, resolving the contradiction between stability and simplicity
Solution Approach 2:
The positioning portions extend from the outer shell in a direction perpendicular to the circuit board surface, adding a new dimensional element for mechanical engagement. This extends the connection from merely vertical solder joints to include lateral mechanical support, preventing detachment under impact while maintaining manufacturing simplicity
2Strength
If the metallic shell and outer shell are integrated into one piece, then the structure is simpler, but the manufacturing complexity increases and structural strength is reduced
Solution Approach 1:
The connector shell is segmented into a metallic shell and an outer shell that can be manufactured separately and assembled. This allows each component to be optimized for its specific material properties and manufacturing process, improving overall structural strength while enabling more flexible and potentially simpler manufacturing of individual parts
Solution Approach 2:
The connector employs a composite structure combining metallic shell material with outer shell material. This composite approach allows each material to be selected for its optimal properties - the metallic shell provides structural strength and EMI shielding, while the outer shell provides positioning features and insulation, resolving the contradiction between strength and manufacturing complexity

AI summary
A standing-type electrical receptacle connector includes a metallic shell, an insulated housing, and an outer shell. The metallic shell defines a receiving cavity therein. The insulated housing is received in the receiving cavity and includes a base portion and a tongue portion extending from one side of the base portion. The outer shell includes a sleeve enclosing the metallic shell, two or more extending sheets respectively extending from two sides of the sleeve, and two or more positioning portions at the extending sheets. The extending sheets are abutted against a circuit board. The circuit board defines positioning holes positioned with the positioning portions.
