Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing structure of fixing electrical components, such as coil assemblies, to a housing using press-fit terminals is prone to dislodgment under external forces, leading to potential dropping off from the control board.
Innovation Solution
An electrical component assembly with an adhesive margin facing the base body, combined with a protruding rib for press-fitting into a housing groove, ensures secure fixation and accurate positioning of the connection terminal, preventing dislodgment and allowing for easy connection to the control board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical component is fixed to housing only through press-fit terminal connection, then assembly structure is simple, but electrical component may drop off under excessive external force
Solution Approach 1:
The patent combines two fixation methods: press-fit terminal connection and adhesive bonding. The electrical component is simultaneously connected to the housing via press-fit terminals and bonded using adhesive material, merging mechanical connection with chemical bonding to achieve both structural simplicity and fixation reliability.
Solution Approach 2:
The patent applies adhesive material in advance to the housing or electrical component before assembly. This preliminary action ensures that the adhesive is already in position and ready to bond, preventing the electrical component from dropping off while maintaining a simple press-fit terminal connection structure.
2Manufacturing precision
If electrical component is securely fixed to base body, then connection terminal positioning is accurate, but manufacturing process becomes more complex
Solution Approach 1:
The patent introduces adhesive material as an intermediary substance between the housing and electrical component. This intermediary enables precise positioning of the connection terminal while the adhesive compensates for minor positioning variations, achieving accurate terminal alignment without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The patent changes the bonding parameter from purely mechanical (press-fit) to a combination of mechanical and chemical (adhesive bonding). This parameter change allows for accurate terminal positioning through the adhesive's bonding characteristics while maintaining ease of manufacture through the simplicity of the press-fit connection.

Function Achieved in This Case
This configuration effectively prevents electrical components from dropping off while maintaining a simple connection structure, improving fitting efficiency and reducing costs by ensuring precise terminal placement and secure adhesion.
Implementation Method 1
the electrical component and the housing are fixed to a surface of a base body, the electrical component includes a connection terminal to be press-contacted into a throughhole of a control board provided in the housing, and the direction of the connection terminal being inserted into the throughhole is the same as that of the electrical component being fitted to the housing, characterised in that the electrical component is provided with an electrical component adhesion margin facing said surface of the base body, so as to be fixed to the base body by an adhesive interposed between the base body and the electrical component adhesion margin
Implementation Method 2
the electrical component is provided on the outer surface thereof, perpendicular to the direction of said assembling, with a protruding rib to be press-fitted into a groove of the housing

AI summary
An electrical component assembly suitably prevents electrical components from dropping off, while adopting a simple structure of connection by a connection terminal to a control board. The electrical component assembly includes a housing (202) in which the electrical components are fitted, and the electrical components and the housing are fixed to a surface of a base body (100). The electrical component includes a connection terminal to be press-contacted into a throughhole (201a) of a control board (201) of the housing (202). The electrical component is provided with an electrical component adhesion margin (S2) facing said surface of the base body 100, so as to be fixed to the base body (100) by an adhesive interposed between the base body (100) and the electrical component adhesion margin (S2).
