Damper component for reducing bouncing effect on circuit breaker contacts during switch on process

A circuit breaker, comprising:

• a switch;
• a linkage assembly coupled to the switch;
• a set of stationary contacts;
• a set of moving contacts coupled to the linkage assembly;
• a spring coupled to the set of moving contacts;
• and
• a damper component comprising a shock absorbing material and coupled to the linkage assembly;
• wherein:
• the switch rotates from an off position corresponding to an off mode of the circuit breaker to an on position corresponding to an on mode of the circuit breaker,
• in response to the rotation of the switch, the linkage assembly moves from a first position corresponding to the off mode of the circuit breaker to a second position corresponding to the on mode of the circuit breaker,
• the movement of the linkage assembly from the first position to the second position reduces a force applied by the linkage assembly on the spring causing the set of moving contacts to engage with the set of stationary contacts,
• the engagement of the set of moving contacts with the set of stationary contacts produces a shock, and
• the damper component collides with an element of the linkage assembly to absorb at least a portion of the shock thereby reducing a bouncing effect between the set of moving contacts and the set of stationary contacts.

A method of manufacturing a circuit breaker that reduces a bouncing effect between a set of moving contacts and a set of stationary contacts of the circuit breaker, the method comprising:

• positioning a switch configured to rotate from an off position corresponding to an off mode of the circuit breaker to an on position corresponding to an on mode of the circuit breaker;
• coupling a linkage assembly to the switch, the linkage assembly configured to, in response to a rotation of the switch, move from a first position corresponding to the off mode of the circuit breaker to a second position corresponding to the on mode of the circuit breaker;
• coupling the set of moving contacts to the linkage assembly;
• coupling a spring to the set of moving contacts;
• and
• coupling a damper component comprising a shock absorbing material to the linkage assembly;
• wherein:
• the movement of the linkage assembly from the first position to the second position reduces a force applied by the linkage assembly on the spring causing the set of moving contacts to engage with the set of stationary contacts,
• the engagement of the set of moving contacts with the set of stationary contacts produces a shock, and
• the damper component collides with an element of the linkage assembly to absorb at least a portion of the shock thereby reducing the bouncing effect between the set of moving contacts and the set of stationary contacts.
