Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
MPO fiber optical connectors have insufficient structural strength at welded portions, and the housing and PCB are not fixedly positioned, leading to signal loss due to misalignment of insertion cores.
Innovation Solution
A fiber optical connector design featuring a one-piece connector housing with pins and mechanical engaging structures for precise alignment, including positioning blocks and a fixation socket member, which ensures stable assembly and precise alignment with the PCB, enhancing structural strength and manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If welding is used to manufacture the housing, then the housing can be assembled from two shells, but the structural strength at the welded portion is insufficient and burrs are easily formed
Solution Approach 1:
The patent merges two separate shell structures into a single integrated housing body. The housing is designed as one piece with a receiving space formed directly within it, eliminating the need for welding two shells together. This integration resolves the technical contradiction by providing both ease of manufacture (through single-piece molding) and high structural strength (without weak welded joints).
2Device complexity
If the housing and PCB are not fixedly positioned, then the assembly process is simpler, but the PCB may swing relative to the housing causing misalignment of insertion cores and signal loss
Solution Approach 1:
The patent incorporates positioning blocks directly into the housing structure during the molding process, before assembly. These positioning blocks protrude into the PCB and pre-establish the correct spatial relationship between the housing and PCB. This preliminary positioning action ensures that when the PCB is installed, the insertion cores are automatically aligned with high precision, resolving the contradiction between simple assembly and precise alignment.
3Extent of automation
If mechanical engaging structures are used for assembly, then automatic manufacturing is enabled, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into integrated structures: the positioning blocks are formed directly in the housing during molding, the pins are pre-assembled on the housing, and the receiving space is built-in. This integration reduces the number of separate components and assembly steps, enabling automatic manufacturing while actually simplifying the overall device complexity compared to traditional multi-component designs.

AI summary
A fiber optical connector includes a connector housing and an optical-fiber component. The connector housing includes a receiving space. Two ends of the connector housing respectively form a first connector opening and a second connector opening. The first connector opening and the second connector opening communicate with the receiving space. Plural pins are assembled on a side surface of the connector housing, and the optical fiber component is inserted into the receiving space from the first connector opening. The connector housing has an improved structural strength. The assembling between the pins and the circuit board allows the connector to be fixedly positioned with the circuit board.
