Electromagnetic Contactor Integrated Shock-Absorbing Rib
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic contactors require a separate shock-absorbing material, increasing the number of components and manufacturing costs.
Innovation Solution
An electromagnetic contactor with a first and second frame made of synthetic resin, where a shock-absorbing rib is integrally formed in the bottom portion of the first frame to support the fixed core, eliminating the need for a separate shock-absorbing member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate shock-absorbing rubber member is disposed in the fixed insulating base, then the shock-absorbing effect is achieved, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The shock-absorbing function is merged into the frame structure by forming shock-absorbing ribs integrally with the frame body. This eliminates the need for a separate shock-absorbing member while maintaining the shock-absorbing effect, directly resolving the contradiction between achieving shock absorption and reducing component count
Solution Approach 2:
The frame is designed to serve multiple functions: structural support, positioning, and shock absorption. The shock-absorbing ribs are formed as an integral part of the frame, allowing the frame to simultaneously provide mechanical support and absorb impact forces, thereby reducing the total number of components needed
2Object-affected harmful factors
If a separate shock-absorbing rubber member is disposed in the fixed insulating base, then the shock-absorbing effect is achieved, but manufacturing cost increases
Solution Approach 1:
The shock-absorbing function is merged into the frame structure through integral formation of shock-absorbing ribs. This eliminates the need for separate procurement, inventory management, and assembly operations for a dedicated shock-absorbing member, thereby reducing manufacturing costs while maintaining the shock-absorbing effect
Solution Approach 2:
The shock-absorbing ribs are formed from the same material as the frame body, eliminating the need for additional materials. This single-material approach simplifies the manufacturing process and reduces material costs compared to using separate rubber components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated shock-absorbing rib reduces the number of components and manufacturing costs while providing a shock-absorbing effect, effectively absorbing impact forces during core collisions.
Implementation Method 1
a shock-absorbing rib integrally formed in a bottom portion of a bottomed tubular section of the first frame to support the fixed core of the operating electromagnet
Implementation Method 2
an operating electromagnet in which a fixed core is fixed in the first frame and a movable core is disposed in the second frame

AI summary
An electromagnetic contactor in which a shock-absorbing member is integrally formed in a frame. The electromagnetic contactor includes a first frame in which an operating electromagnet is disposed and coil terminals which supply power to a coil of the electromagnet is formed to project from a side surface, and a second frame in which a contact mechanism having an auxiliary contact is disposed and has power source side terminals on one end side and load side terminals on the other end side, and in the first frame and the second frame, a snap fit is formed which can attach the second frame to the first frame in both of a normal direction coupled state where the coil terminals and the power source side terminals face the same direction and a reverse direction coupled state in which the coil terminals and the load side terminals face the same direction.
