Fire Detector Mounting Base With Rotating Locking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire detector and alarm installation bases require lengthy assembly times due to the need for precise alignment and securement of wires, which is inefficient and time-consuming.
Innovation Solution
The installation base features a locking assembly that rotates and/or presses to switch between locked and released positions, utilizing conductive assemblies to quickly establish electrical connections and facilitate maintenance by holding wires in place when locked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal fasteners and mechanical structures are used to press wires onto a metal guide plate, then electrical connection is realized, but assembly time becomes relatively long due to alignment and securing requirements
Solution Approach 1:
The patent combines the mechanical fastening function and the electrical conduction function into a single integrated assembly. The locking assembly includes both a fastening component (locking member with locking portion) and a conductive component (conductive plate with conductive portion), which work together as one unit to simultaneously secure the wire mechanically and establish electrical connection, eliminating the need for separate fastening and wiring operations.
Solution Approach 2:
The locking assembly serves multiple functions: it acts as both a mechanical fastener (securing the wire to the guide plate) and an electrical conductor (providing the electrical connection path). The locking member and conductive plate are designed to perform both structural support and electrical conduction simultaneously, reducing the number of components and assembly steps required.
2Reliability
If precise alignment and securement of wires are performed manually, then reliable electrical connection is achieved, but installation efficiency decreases
Solution Approach 1:
The locking assembly is designed to automatically guide and position itself during installation. The locking member fits into the installation hole and the locking portion engages with the guide plate in a self-aligning manner, reducing the need for manual alignment operations. The integrated design allows the assembly to self-position and self-secure while establishing electrical contact.
Solution Approach 2:
The locking assembly is pre-configured with the conductive plate and locking member in fixed spatial relationships. The conductive plate is positioned to make contact with the guide plate, and the locking member is arranged to engage with the installation hole, so that when the assembly is installed, the electrical connection and mechanical fastening occur simultaneously without requiring sequential adjustment operations.

AI summary
The present application provides an installation base, and a fire detector or a fire alarm. The installation base includes: a base body, which has a plurality of installation holes; locking assemblies, which are arranged in the installation holes of the base body, and which are switched between a locked position and a released position relative to the installation holes when the locking assemblies are rotated and/or pressed; and conductive assemblies, which hold wires when the locking assemblies are switched to the locked position so that electrical conduction is realized. In the installation base for a fire detector or a fire alarm according to the present application, through a cooperation of the locking assemblies, the base body and the conductive assemblies, quick electrical connection and maintenance of the installation base are realized.
