Striplight Printed Circuit Board Fixing Without Snap Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing striplight structure is complicated and costly due to the need for snap rings to fix the printed circuit board, which also increases assembly time and reduces aesthetics.
Innovation Solution
A striplight design featuring insulated lamp holders with mounting slots and metal sockets that securely hold the printed circuit board without snap rings, using elastic metal members for electrical connections and a protective ring for enhanced waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If snap rings are used to fix the printed circuit board in the lamp tube, then the printed circuit board can be securely fixed, but the structure becomes complicated and the cost of raw materials increases
Solution Approach 1:
The patent integrates the fixing function directly into the lamp holder structure by designing mounting slots that receive the printed circuit board. The lamp holder body itself becomes the fixing mechanism, merging the support and fixation functions into a single component, thereby eliminating the need for separate snap rings and reducing structural complexity.
Solution Approach 2:
The patent removes the snap ring component from the assembly by incorporating its fixing function directly into the lamp holder. The mounting slots are formed directly in the lamp holder body, extracting the unnecessary intermediate component and simplifying the overall structure while maintaining fixation stability.
2Stability of the object's composition
If snap rings are used to fix the printed circuit board, then the board can be secured in place, but the assembly process becomes more complicated and assembly time increases
Solution Approach 1:
The lamp holder is designed with integrated mounting slots that perform both support and fixation functions simultaneously. During assembly, the printed circuit board is inserted directly into the mounting slots formed in the lamp holder body, combining multiple operations into a single step and improving assembly efficiency.
3Stability of the object's composition
If snap rings are provided inside the lamp tube, then the printed circuit board can be fixed, but the aesthetics of the striplight are decreased
Solution Approach 1:
The patent removes the visible snap ring component from the lamp tube interior by integrating its fixation function into the lamp holder structure. The mounting slots are formed within the lamp holder body, hiding the fixation mechanism and maintaining the aesthetic appearance of the striplight while still securing the printed circuit board effectively.

AI summary
This application discloses a striplight, which includes a lamp tube, a printed circuit board arranged in the lamp tube, a light-emitting element arranged on the printed circuit board, two insulated lamp holders respectively inserted at both ends of the lamp tube, and metal sockets connected with the insulated lamp holders; both ends of the printed circuit board have electrical connectors electrically connected with the metal sockets; the inner wall of the insulated lamp holder has at least one mounting slot, and the printed circuit board is inserted into the mounting slot. A mounting slot adapted to the edge of the printed circuit board is provided inside the insulated lamp holder, i.e., the edge of the printed circuit board is accurately inserted into the mounting slot after the insulated lamp holder and the lamp are assembled, to fix the printed circuit board in the tube. The printed circuit board is fixed in the lamp tube without snap rings or other components, thereby effectively simplifying the structure of the striplight and reducing the cost of the striplight.
