Optical Fiber Terminal Box Independent Base Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access terminal boxes require detachment of the protective cover to separate the base from the base plate, risking damage to coiled fibers during mounting and detachment by non-professional personnel.
Innovation Solution
The access terminal box design includes a protective cover with a first detachable structure that allows the base to be fastened inside an open-mouthed box structure, and a second detachable structure using locking hooks and slots that enable secure fastening without requiring detachment of the protective cover, allowing safe mounting and detachment by non-professionals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base is fastened to the base plate using a locking hook and locking slot that require detachment of the protective cover, then the fastening is secure, but the ease of operation deteriorates and fiber damage risk increases
Solution Approach 1:
The detachable structure is divided into two independent parts: a locking hook on the base and a locking slot on the base plate. This segmentation allows the base to be detached from the base plate directly without requiring removal of the protective cover, resolving the contradiction between secure fastening and ease of operation.
2Stability of the object's composition
If the locking hook is hidden inside the protective cover, then the protective cover provides complete enclosure, but the ease of operation deteriorates as non-professional personnel cannot easily access the locking mechanism
Solution Approach 1:
The locking hook is extracted from inside the protective cover and repositioned on the base, with its locking tip extending outward. This allows non-professional personnel to easily access and operate the locking mechanism without removing the protective cover, while still maintaining complete enclosure when locked.
3Ease of operation
If the base is detached from the base plate by first removing the protective cover, then the locking mechanism is accessible, but the fiber coiled on the base is likely to be damaged
Solution Approach 1:
The detachable structure separates the locking function from the protective cover, allowing the base to be detached from the base plate independently. This eliminates the need to remove the protective cover during detachment operations, thereby protecting the coiled fiber from damage by non-professional personnel.

AI summary
The present invention discloses an access terminal box and pertains to the communications field. The access terminal box includes a protective cover, a base, and a base plate, where the protective cover includes a cover plate and side walls that are disposed around the cover plate, the cover plate and the side walls form an open-mouthed box structure, the base is fastened inside the open-mouthed box structure of the protective cover by using a first detachable structure, the base is fastened to the base plate by using a second detachable structure, the second detachable structure includes a first locking hook that is arranged to protrude from a bottom plane of the base and a first locking slot that is correspondingly arranged on the base plate, and the first locking hook and the first locking slot lock to fasten the base to the base plate. In embodiments of the present invention, when the base is to be detached from the base plate, it is not required to first detach the protective cover; therefore, a fiber coiled on the base can be better protected, damage to the fiber can be avoided, and it is suitable for non-professional personnel to detach the access terminal box.
