Circuit Breaker Mechanism To Facilitate Automated Assembly

View page
US Patent:
7812272, Oct 12, 2010
Filed:
Sep 15, 2006
Appl. No.:
11/521910
Inventors:
Dennis William Fleege - Cedar Rapids IA,
Eugene Walter Wehr - Cedar Rapids IA,
International Classification:
H01H 9/00
H01H 19/62
H01H 27/00
US Classification:
200 17R, 200401
Abstract:
A layered mechanism for use in a circuit breaker fabricated by automated assembly operations includes a movable electrical contact mounted on a blade for movement relative to a stationary electrical contact. The major portion of the blade is substantially flat, and a handle is coupled to the blade to move said blade. A toggle spring is connected to the blade to apply a biasing force in the plane of the flat portion of the blade. The handle and blade form cooperating opposed surfaces that allow engagement of the handle with the blade so that movement of the handle can move the blade while allowing pivoting movement of the blade relative to the handle, while opposed surfaces resist upward pivoting movement of the blade when the toggle spring is attached to the blade during assembly of the circuit breaker.

US Patent:
2013033, Dec 19, 2013
Filed:
Jun 18, 2012
Appl. No.:
13/526154
Inventors:
Eugene Wehr - Cedar Rapids IA,
Assignee:
Schneider Electric USA, Inc. - Palatine IL
International Classification:
H01H 33/08
H01H 11/00
US Classification:
218157, 29622
Abstract:
A circuit breaker having an increased interrupting rating without increasing the size of the circuit breaker while maintaining full compliance with UL and IEC standards. An adhesive is applied to a bottom surface near the exhaust outlets of interrupters. The interrupter housing is formed by joining two pieces, and the adhesive is applied across both pieces. The adhesive adheres to a bottom interior surface of a base of the circuit breaker, anchoring the interrupter assembly to the base. The adhesive prevents the two pieces of the interrupter housing from separating during an interruption event, and prevents the interrupter assembly from being lifted away from the base during the interruption event. The adhesive can act as a barrier to prevent interruption gas and pollution that do not escape out of the exhaust ports of the base from entering between the bottom of the interrupter assembly and the interior of the base.

Electrical Contact For Use In A Circuit Breaker And A Method Of Manufacturing Thereof

View page
US Patent:
5831186, Nov 3, 1998
Filed:
Apr 1, 1996
Appl. No.:
8/626706
Inventors:
Jon W. Oswood - Cedar Rapids IA
James P. Bodin - Cedar Rapids IA
Randy L. Siebels - Cedar Rapids IA
Eugene W. Wehr - Cedar Rapids IA
Assignee:
Square D Company - Palatine IL
International Classification:
B22F 312
B22F 500
US Classification:
75243
Abstract:
An electrical contact for use in an electrical switching device is provided having low contact resistance, high wear resistance and high anti-weld characteristics. The contact includes a material composition of between 0. 2 and 8% by weight Gr, between 10 and 90% by weight W and the remaining mixture consisting of Ag. The contact is manufactured using a process which yields a unique microstructure characterized by not having an interconnected Gr network around the Ag thereby providing a strong Ag to Ag bond. This process includes the steps of adding the appropriate amounts of Ag, W and Gr powder material together, blending together under low shear conditions to provide a homogenous powder mixture while prohibiting the Gr from smearing onto the Ag, pressing the material mixture to form a contact, and then sintering and coining the contact.

Improved Calibration Means For A Circuit Breaker

US Patent:
5821839, Oct 13, 1998
Filed:
Aug 23, 1996
Appl. No.:
8/697383
Inventors:
James Arthur Heise - Cedar Falls IA
Duane Lee Turner - Cedar Rapids IA
Dennis William Fleege - Cedar Rapids IA
Eugene Walter Wehr - Cedar Rapids IA
Assignee:
Square D Company - Palatine IL
International Classification:
H01H 7512
US Classification:
335 35
Abstract:
A circuit breaker device for interrupting current in a circuit path between a source and a load includes a first contact and a second contact cooperatively arranged in the circuit path so as to provide current from a source to a load. A trip mechanism assembly, which includes an armature, a bimetal and a yoke, is provided for interrupting the current. The armature includes an aperture in which a latch point is provided to engage a latching surface of a trip lever for latching the trip lever thereon. The amount of current that is required to cause the trip mechanism to interrupt the circuit path is determined by the amount of overlap between the latching surface and the latch point. This overlap is adjusted by bending a calibration plate by tightening a calibration screw which extends through an aperture in a circuit breaker housing and a slotted aperture in the calibration plate. A substantially square shaped nut secures the calibration screw tightly against the housing.

In particular, the circuit breaker operating mechanism which operates the contacts thereof to make or break the electric circuit is formed of elements designed to interact in a Z-axis assemblable fashion. The movable contact is defined on a contact carrier or blade assembly which is adapted for Z-axis assembly and also provides increased arc erosion resistance and improved opening of the breaker contacts.

Anti-Rebound Latch

View page
US Patent:
4612430, Sep 16, 1986
Filed:
Dec 21, 1984
Appl. No.:
6/684540
Inventors:
Dallas Sloan - Cameron WI
Donald R. Venzke - Cedar Rapids IA
Eugene Wehr - Cedar Rapids IA
Assignee:
Square D Company - Palatine IL
International Classification:
H01H 7710
US Classification:
200327
Abstract:
An anti-rebound latch having a generally U-shaped housing which defines a central blade path opening between first and second side legs. The housing supports a pivotally mounted generally crescent shaped drive-arm which includes a kicker portion at one end positioned adjacent the top of the blade path opening and a pusher portion at its opposite end. The drive-arm is operatively associated with a blade catcher carried by the first side leg which is reciprocally movable between a first position in which no part of the blade catcher extends into the opening and a second position in which the catcher extends across the opening to the second side leg. The catcher is spring biased to its first position. The opposite side leg may carry a pole face which attracts the catcher in response to the blow-open movement of a contact blade within the opening which hits the kicker portion of the drive-arm causing pivotal movement of the drive-arm which results in the pusher portion of the drive-arm sliding the catcher into the blade path opening towards the second side leg. As a result of electromagnetic forces generated, the pole face attracts the catcher toward its second position which prevents rebound movement of the blade to a closed position.
