Abstract
A contact bounce reduction system including: a movable member, and a contact bounce damping device including: a body, a first ball and a second ball, a first resilient member and a second resilient member, a piston. The first resilient member holds the first ball in the seat and the second resilient member holds the second ball in the seat when the piston is in a default extended position, and a third resilient member biases the piston towards the default extended position. The movable member actuates the piston towards the retracted position, causing the first ball and the second ball to move radially out from the seat, and the third resilient member to accumulate energy.
Claims12
A contact bounce reduction system comprising:
- a movable member, and
- a contact bounce damping device comprising:
- a body,
- a first ball and a second ball arranged in the body,
- a first resilient member and a second resilient member,
- a piston partly arranged in and extending from the body, the piston being configured to be moved linearly between a default extended position and a retracted position relative to the body, and wherein the piston has a radial seat configured to partly receive the first ball and the second ball,
- wherein the first resilient member is configured to act with a radial force onto the first ball to hold the first ball in the seat when the piston is in the default extended position,
- wherein the second resilient member is configured to act with a radial force onto the second ball to hold the second ball in the seat when the piston is in the default extended position, and
- a third resilient member configured to bias the piston towards the default extended position;
- wherein the movable member is configured to move from a non-contact position relative to the piston to contact the piston and actuate the piston from the default extended position towards the retracted position with a force greater than a threshold value, causing the first ball and the second ball to move radially out from the seat, and the third resilient member to accumulate energy, and
- the contact bounce reduction system further comprising a contact ring slidably arranged around the piston, and a fixed contact member electrically connected to the contact ring.
