Abstract: An electronic component handler includes a region where an electronic component placement unit on which an electronic component is placed is capable of being disposed. A laser light source emits light toward the electronic component placement unit placed in the region. A capturing unit is capable of capturing an image of the electronic component and irradiated with the light. A processor determines the presence or absence of the electronic component in the electronic component placement unit based on the image. In the image, the processor sets a first candidate region and a second candidate region from an electronic component placement region which is a region where the electronic component is placed, determines a selected region by comparing the first candidate region and the second candidate region to each other, and performs the determination based on the selected region.

Abstract: A circuit breaker includes a rectangular box-shaped intermediate housing and lower housing; a power supply side fixed contact and a load side fixed contact disposed in the intermediate housing and facing each other; and a movable contact housed in the lower housing for bridging the power supply side fixed contact and the load side fixed contact. The lower housing has arc gas emission holes formed in front and rear walls thereof, and is connected to a lower part of the intermediate housing via an engagement part such that the lower housing covers the lower part of the intermediate housing. A thin wall portion is formed in each of the front and rear walls to eject arc gas by bending.

Abstract: A breaking mechanism includes a latch receiver engaging a latch to allow a movable contact shoe to be closed, and a tripping device for rotationally driving the latch receiver to disengage the latch to open the movable contact shoe. An engaging surface of the latch engaging the latch receiver is formed as a projecting circular surface, whereas an engaging surface of the latch receiver engaging the projecting circular surface is formed as a recessed circular surface having a radius of curvature greater than that of the projecting circular surface. The center of the curvature of the recessed circular surface coincides with the axis of a support shaft supporting the latch receiver. The loads causing a tripping device to drive the latch receiver do not change even if the location of an engaging point is changed.

Abstract: A circuit breaker is formed of a main body case made of resin and divided into a lower case, an upper cover, and an intermediate case, into which parts of the circuit breaker are integrated. The intermediate case has pocket shaped sockets formed on a top surface side thereof, into which the tips of the interphase partition walls provided in the upper cover are fitted. Also, the intermediate case has recessed grooves formed on a bottom surface side thereof to fit over upper edges of the interphase partition walls provided in the lower case. Thus, the circuit breaker can be assembled easily and becomes more rigid.

Abstract: In a slow-make type circuit breaker for opening and closing a main circuit contact in synchronism with the manual operation of a rotary operation handle, a ratchet unit 12 as an artificial quick-make means for forcibly increasing the operating force of the operation handle in the middle of a stroke for ON operation of the contact is constituted by a convex cam 11 made of metal and coupled with the operation handle 5, a ratchet 12b made of metal and disposed at a point close to an ON position of the operation handle so as to face the cam, a driving spring 12c for pressing the ratchet toward a rotary movement path of the cam, and a ratchet case 12a in which these parts are incorporated. The unit is fabricated inside a cover 1b of a circuit breaker body. Here, the cam and the ratchet are formed as common parts, and the driving spring is selected in accordance with the kind of circuit breaker.

Abstract: In a circuit breaker, a rotary-operating handle is linked with an opening and closing mechanism via a driving gear so that main circuit contacts can be opened and closed by rotating an opening and closing lever. A vertically moving handle lock lever is arranged between a tip of the opening and closing lever and the driving gear directly coupled to the operating handle, so that when the main circuit contacts are opened after being welded, the lock lever abuts against the driving gear to restrain the operating handle to the vicinity of the ON position, thereby restricting the movement to a contact-open indicating position. Further, an upward-inclined surface is formed in a stopper section located at a tip of the lock lever, so that if the contact welding is not severe, the lock lever can be pushed down to forcibly open the contacts.

Abstract: A circuit breaker includes an opening and closing mechanism section with an opening and closing lever, and an alarm-outputting plate operating in response to a tripping operation. A case for the circuit breaker has a plurality of switch housing sections formed on a top side thereof, in which are installed an auxiliary switch for detecting an ON/OFF state of a main circuit contact and/or an alarm switch for detecting a tripping operation. The opening and closing lever and the alarm-outputting plate have outputting projecting pieces, respectively, laterally spaced apart from each other corresponding to the respective housing sections, for transmitting mechanical output signals to the switches. When the auxiliary and alarm switches are installed, the auxiliary switch is linked to the outputting projecting piece of the opening and closing lever, while the alarm switch is linked to the outputting projecting piece of the alarm-outputting plate.

Abstract: A handle-operating mechanism for a circuit breaker includes a rotary operating handle for opening and closing a main-circuit contact of a circuit breaker, a rotating gear operably connected to the operating handle and having a first engaging device, and a contact opening-and-closing mechanism having a toggle gear meshing with the rotating gear. A clutch gear is connected to the operating handle to be interposed between the operating handle and the rotating gear, and has a second engaging device. An idle stroke is formed such that when the circuit breaker is turned on, the operating handle runs idly after rotation of the operating handle has been started and before the second engaging device engages the first engaging device to drive the rotating gear for actuating the toggle gear.
