Automotive Precision Springs

Leaf Springs for Holding

Spring for holding are springs that hold parts in place by pressing down on them. The lineup includes overlapping plate springs, tapered leaf springs, and grid springs. They are used in power control units of electric and hybrid vehicles.

Example of Hold Down Spring Usage

Laminated Leaf Springs (Holding Springs)

Laminated Leaf Springs (Holding Springs)

Laminated leaf springs adhere semiconductors to cooling media in inverters for EV and HEV motor control. Various shapes are available as needed, for example, laminated leaf springs, thin leaf springs, disc springs, and corrugated springs. They can also be applied for pressing for battery cells and fuel cell stacks.

Tapered Leaf Springs (Holding Springs)

Tapered Leaf Springs (Holding Springs)

Serving the same function as laminated leaf springs, i.e. adhering semiconductors to cooling media in inverters for EV and HEV motor control, tapered leaf springs optimize stress by gradually changing the plate thickness into a tapered shape, thereby realizing a single sheet.

Spring Grid Array

Spring Grid Array

The spring grid array is a sheet spring consisting of several hundred small leaf springs. It can be used for applications such as vibration isolation, heat transfer, and electric current conduction.
