Optical Connector Spring Pressing Portion Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical connectors with a coil spring and spring pressing portion face interference issues during the terminating operation of the optical ferrule due to the close proximity of the spring pressing portion and the coil spring, making it difficult to securely attach and grind the optical fibers.
Innovation Solution
The optical connector features a spring pressing portion formed from two half bodies that combine to create an optical fiber inserting through-hole and a spring reception portion, allowing for easier assembly and termination of the optical ferrule without interference, with engagement protrusions and recessions for secure coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the spring pressing portion is made as an integral molding article, then the structure is simple and easy to manufacture, but the optical fiber inserting through-hole has no room for passing the coating portion of the optical fiber cord, causing interference during terminating operation
Solution Approach 1:
The spring pressing portion is divided into two separate half-bodies that are assembled together. This segmentation allows the optical fiber inserting through-hole to be formed with sufficient space for the coating portion of the optical fiber cord, eliminating interference during the terminating operation while maintaining manufacturing simplicity through modular assembly
2Device complexity
If the spring pressing portion and coil spring are disposed close to each other, then the device complexity is reduced, but the terminating operation of the optical ferrule is interfered with
Solution Approach 1:
By segmenting the spring pressing portion into two half-bodies, the design maintains compact arrangement of components while providing sufficient space for the optical fiber cord coating portion to pass through without interfering with the terminating operation of the optical ferrule
3Length of moving object
If the optical fiber portion length is regulated to predetermined length or less, then the assembly is compact, but there is no room for passing the coating portion in the optical fiber inserting through-hole
Solution Approach 1:
The spring pressing portion is segmented into two half-bodies, creating an optical fiber inserting through-hole with sufficient cross-sectional area to accommodate the coating portion of the optical fiber cord, enabling easy passage even when the optical fiber portion length is regulated to predetermined length or less

AI summary
An optical connector includes a connector housing; an optical ferrule that is housed in the connector housing; a coil spring that is housed in the connector housing and impresses the optical ferrule in a forward direction; and a spring pressing portion that is attached to an rear end of the connector housing, has an optical fiber inserting through-hole and a spring reception portion, and receives a reaction force of the coil spring. The spring pressing portion is divided into two half bodies. Since the spring pressing portion is divided into two parts, at the time of assembly of the optical connector, the optical ferrule is attached to the optical fibers and is terminated, and then the optical fibers can be covered with the spring pressing portion. At the time of the terminating operation, since there is no spring pressing portion that causes interference in the operation, it is easy to perform the terminating operation of the optical ferrule.
