US Patent:

48864625, Dec 12, 1989

Filed:

Feb 1, 1988

Appl. No.:

7/150889

Inventors:

Joseph Fierro - Trenton NJ

Assignee:

Heinemann Electric Company - Lawrenceville NJ

International Classification:

H01R 909

US Classification:

439 79

Abstract:

A connector receptacle is provided with one flat external side for application to a printed circuit board. The connector receptacle has enclosing guiding walls terminating in a latch element. At least a pair of conductive female connectors are provided within slots in the connector receptacle. Each of these pieces providing the connectors consists of a pair of aligned female conductors integral with a pin connector support interconnected through a bridge and is formed of a single piece of sheet metal. The bridge also extends between the aligned pair of female conductors and supports a transversely extending spring tab which is used to enter a transverse slot in the connector receptacle to hold the integral piece in place. The female connector pieces are reversible for use in the slots provided on opposite sides of the connector receptacle. The circuit breaker, having electric terminal connectors which cooperate with the female connectors of the receptacle, is modified to provide a latch element extending in the direction of the terminal connectors from the circuit breaker and cooperative with the latch element on the connector receptacle to engage and hold the circuit breaker in position with the terminal connectors engaged with the female connectors of the connector receptacle.

Appl. No.:

7/428067

Inventors:

Joseph Fierro - Trenton NJ

Assignee:

Heinemann Electric Company - Lawrenceville NJ

International Classification:

H01H 3308

US Classification:

200293

Abstract:

A circuit protector employs molded resinous parts including a base and a support frame structure. Advantageously the circuit protector support frame structure may include a medial plane frame providing space for two circuit protectors, one on each side of the frame and a common back plane mutually perpendicular to the medial frame and the base along one edge of the base. A cover fits over the support frame and base and snugly accommodates the base at its terminal edges except immediately along the back plane. The back plane is provided with a slot through the back plane in the vicinity of each pair of contacts which communicates to a space between the cover and the back plane of the base permitting venting of gases generated by arcing. Grooves are supplied in the medial plane frame and the back plane to accommodate edge flanges of an arc suppressing grid to hold the grid in place to bracket the contacts.

Heinemann Electric Company - Lawrenceville NJ

International Classification:

H01H 7116

US Classification:

Abstract:

A two pole breaker employs molded resinous parts including a base and support frame structure. Supported to a medial plane frame by a pin is a rocker handle having a linkage crank arm at each side of the medial plane and a rotatable latch lever having trip surfaces accessible to a bi-metallic overload actuator of each pole. A rocker member generally transverse to the normal position of the latch lever has a latch surface which cooperates with a latch keeper on the latch lever which is held engaged by a spring between the latch lever and the medial plane. The rocker has parallel side members, each supporting a switch actuator surface on each side of the medial plane frame. Identical linkage connections on each side of the medial plane connect the crank arms to the respective side pieces of the rocker. Overload causes a bi-metal actuator to move the latch lever in opposition to its spring to release the rocker to a position to which the guide slot directs it allowing the contacts to open and moving the handle and linkage pins to a position where they are moved back over center. The handle movement pulls the rocker back up into position to relatch with the latch lever, moving the latch lever out of the way against the action of the spring, if needed.
