| A circuit breaker for interrupting the flow of current upon the detection of excess current or temperature is provided which comprises a housing, a trip armature plate, a trip armature frame, and a bias spring. The trip armature plate has at least two pivot tabs extending laterally on opposite edges that are inserted into a pivot elongated slot, which is located at an open end of the trip armature frame, and a pivot aperture, which is located at the opposite end of the trip armature frame, respectively. A bias spring is used for securing the pivot tabs into the pivot elongated slot and the pivot aperture, and for urging the trip armature plate pivotably outwardly about the pivot tabs away from the trip armature frame. The circuit breaker also comprises a trip cross bar having at least two fingers that are used to engage optional circuit breaker accessories and that are located asymmetrically to allow the interchangeability of the accessories. During top down assembly, the trip cross bar is the last component that is assembled into the circuit breaker in order to allow the easy installation of other components, including the trip armature frame and trip armature plate. | ||||||

| The insulator comprises three molded segments which are mounted in interlocked end-to-end relation along the drive bar. The two end segments are of fixed length, and the intermediate segment is selectable in length depending upon the length of the drive bar which in turn depends upon the width of the switch. The segments are generally U-shaped in transverse cross-section, and are held in position on the drive bar by a flexible strip of insulating material inserted between spaced shoulders on the end segments after the segments are placed on drive bar. Arc shields may be secured to either or both of the end segments.

| PURPOSE: To reduce manhours for assembling a trip cross bar to a side plate. CONSTITUTION: An L-shaped bending portion 9a is formed in a supporting pin 9 inserted between a supporting fitting 3 of a trip cross bar and a side plate 6 of a switch mechanism for rotatably supporting the trip cross bar 1. The L-shaped bending portion 9a abuts against a stopper surface 13 of an insulating bar 2, thereby preventing the supporting pin 9 from being drawn out. Consequently, it is possible to make unnecessary additional machining, which has been conventionally required in order to plastically deform a part of the insulative bar 2 in the vertical direction to prevent drawing-out, after insertion of the supporting pin 9, and a facility for the additional machining.

| PURPOSE: To reduce damage to a moving contact by providing a projection on the side surface of an intermediate bulkhead, and by abutting a part of a holder thereon, so as to regulate the opening distance of the moving contact. CONSTITUTION: A case 1 made of molded resin is partitioned by an intermediate bulkhead 1a into three-phased breaker chambers, and electrifying pass of each polarity is stored in each breaker chamber. A U-shaped groove 20 for burying an opening shaft 11 that connects a holder 10 to the intermediate bulkhead 1a, is provided in such a way that the upper surface is notched by the groove, and a groove 21 for storing an insulating barrier 26 is formed on the periphery of the U-shaped groove 20. A square stopper part 27 for regulating the opening position of a moving contact by abutting a part of the holder 10 on the outside surface of the intermediate bulkhead 1a, is formed in an integrated manner. A stage part 10a is formed on the side surface of the holder 10, and the stage part 10a is abutted on the stopper part 27 of the intermediate bulkhead 1a at the time of opening the moving contact. By regulating the opening position of the moving contact by abutting a part of the holder 10 on the projection 10a provided on the side surface of the intermediate bulkhead 1a, damage to the moving contact is prevented.

| PURPOSE: To improve the rigidity of a contact to prevent the contact from being damaged by the impact form generated when the contact is closed by providing a beam having a substantially thin section along the whole length, a means connected to the beam to mechanically connect a contact operating mechanism to a horizontal bar, and providing an insulating partitioning means. CONSTITUTION: A horizontal bar 10 has a molded part 12 and a horizontal bar beam 14, and the molded part 12 has four insulating barriers 16, three contact blade mounting parts 20 and two horizontal bar beam insulating parts 22 for insulating the horizontal bar between the insulating barriers 16. The beam 14 has two link mechanism connecting parts 18, a substantially I-shaped beam member 32 and a molding tub 34, and each link mechanism connecting part 18 has two tubs 36 mounted on the beam member 32. Thus, a lightweight type horizontal bar having sufficient rigidity can be provided. COPYRIGHT: (C)1990,JPO | ||||||
