Abstract
It is aimed to enable a connecting operation to be easily performed while achieving high connection reliability between a connecting member and a mating connecting member. An electrical connection unit is to be connected to a mating connecting member and includes a connecting member capable of contacting the mating connecting member and a biasing member for applying a contact pressure between the mating connecting member and the connecting member. The biasing member is made of shape-memory alloy memorizing a shape to enhance the contact pressure by a temperature increase.
Claims9
An electrical connection unit to be connected to a mating connecting member, the electrical connection unit being a component for connecting a rotating electric machine and an inverter in a mechanically and electrically integrated unit obtained by integrating the rotating electric machine and the inverter, comprising:
- a connecting member capable of contacting the mating connecting member;
- and
- a biasing member for applying a contact pressure between the mating connecting member and the connecting member,
- the biasing member being made of shape-memory alloy memorizing a shape to enhance the contact pressure by a temperature increase, and
- the biasing member being configured to memorize the shape to enhance the contact pressure by Joule heat of electricity flowing in the mating connecting member and the connecting member in a first connected state of the mating connecting member and the connecting member after the biasing member is attached to the connecting member.
