Abstract
An engageable drive engageable operating mechanism for converting a movement of a linear translation operating handle to a rotating handle movement relative to the operative front face engageable with a molded-case circuit breaker. The mechanism includes an external rotating adapter external rotating operating member or alternatively an engageable drive engageable operating mechanism incorporating a handle assembly external rotating operating member, interchangeable with each other; and a gear, a support movable movement-converting support including a rack portion, and a structural support base, wherein the structural support base includes a built-in side opening chamber.
Claims15
An operating mechanism for a molded-case circuit breaker having an operating handle comprising:
- an external rotating operating member having first and second radially opposing flaps, a support base, and an engageable cross-shaped cavity
- a gear having teeth, a cross-shaped latch, a passing hole, and a ring, wherein the gear being locked and secured to the center of the external rotating operating member;
- a movable movement-converting support having a rack portion having teeth, a through hole, and an adaptation cavity, wherein the rack portion is coupled to the gear;
- a structural support base having a side chamber, and first and second passage recesses;
- wherein as a result of a rotational operating movement of the external rotating operating member, the movable movement-converting support slides linearly in a path analogous to the operating handle of the molded-case circuit breaker, through the adaptation cavity;
- and
- wherein the side chamber incorporates a side opening for the introduction of the movable movement-converting support.
An operating mechanism for a molded-case circuit breaker having an operating handle comprising:
- an external rotating operating member having a center;
- a gear being locked and secured to the center of the external rotating operating member;
- a movable movement-converting support comprising:
- a rack portion coupled to the gear;
- and
- an adaptation cavity;
- a structural support base comprising a side chamber;
- wherein as a result of a rotational operating movement of the external rotating operating member, the movable movement-converting support slides linearly in a path analogous to the operating handle of the molded-case circuit breaker, through the adaptation cavity;
- and
- wherein the side chamber incorporates a side opening for the introduction of the movable movement-converting support.
A method of assembling an external operating mechanism for a molded-case circuit breaker comprising:
- prepositioning a gear having teeth on a movable movement-converting support such that a longitudinal center line T of a cross-shaped latch of the gear is tilted with respect to a longitudinal center line S of a rack portion having teeth of the movable movement-converting support, so that the gear with teeth is positioned between the teeth of the rack portion of the movable movement-converting support so as to allow concentricity between a through hole of the movable movement-converting support with a passing hole of the gear;
- inserting the movable movement-converting support and the gear into a side chamber of a structural support base until a ring of the gear is concentric with a through hole of the structural support base;
- inserting an external rotating operating member into the structural support base through an upper part of the external operating mechanism, from the coincidence of first and second radially opposing flaps of the external rotating operating member in first and second passage recesses of the structural support base until a support base of the external rotating operating member engages a support ring of the support base, where the external rotating operating member is previously inserted so that an engageable cross-shaped cavity of the external rotating operating member is configured coincident with the cross-shaped latch of the gear, assembled together, to provide a mechanical movement engagement between the external rotating operating member and the gear;
- and
- setting a first fixing member in the passing hole of the gear, which passes through the through hole of the movable movement-converting support, both preposed in the side chamber of the structural support base to be fixed next to the passing hole of the gear.
