Abstract: In this breaker device, a pair of stationary electrodes (35, 35) are arranged while the protruding wall (32) is interposed between them and the U-shaped movable electrode (60) is engaged with them so as to close an electric circuit. The protective protruding section (61) is arranged at an upper end of the stationary electrode (35), and the protrusions (62) are provided on both sides of the protective protruding section (61). When the movable electrode (60) is engaged, it is elastically expanded and deformed when it comes into contact with the protrusion (62). Even in a case in which the protrusion (62) is scraped away by the friction caused between the protrusion (62)and the movable electrode (60), since the protrusion (62) is located at a position shifted from the stationary electrode (35), the scraped powder never gets into between the movable electrode (60) and the stationary electrode (35).

Abstract: A connecting tube has a middle portion in the direction of length thereof, which is preliminarily narrowed, and is fixed by being press-fitted into a mounting hole of a shield wall. At a terminal of a shielded cable, an exposed end portion of the shield layer is turned up and put upon a C-ring for underlaying fitted into an end portion of an outer sheath. The shielded cable, on which such terminal processing is performed, is inserted into the connecting tube. A narrowed portion of the connecting tube is caulked so that the shield layer is sandwiched between the narrowed portion of the connecting tube and the C-ring. At that time, at both the front and rear end portions of the caulked portion of the connecting tube, tapering portions, or bellmouths are formed so that their radial dimensions gradually increase in opposite directions, respectively.

Abstract: In a breaker apparatus, from the state where the main circuit is closed, in case where a drive member is moved, in the process while the drive member is moved to an energization preventive position, a driven pin moves within a loose fit groove. While maintaining the state in which two electrodes are not shifted from each other in their separating direction, the relay circuit starts its opening operation to thereby close the main circuit. After then, in case where the drive member is moved further, due to the engagement between the driven pin and inclined groove, the electrodes are separated from each other. Due to provision of the loose fit groove, there can be secured sufficient time to open the main circuit while maintaining the electrodes in their mutual fit state.

Abstract: In the breaker device, a pair of stationary electrodes 20, 21 are arranged on the front and the rear side of the protruding wall 18, that is, the pair of stationary electrodes 20, 21 are collected at one place. Therefore, the pair of stationary electrodes 20, 21 have a space round both the stationary electrodes in common. Accordingly, the size of the breaker device can be reduced. Further, when the radius of curvature of the continuity section 73 connecting the pinching pieces 71, 72 is made large, concentration of stress in the movable electrode 70 can be relieved. Therefore, the pinching forces of both the pinching pieces 71, 72 can be increased. Accordingly, it is possible to ensure a sufficiently high contact pressure between the movable electrode 70 and the stationary electrodes 20, 21.

Abstract: In a circuit breaker, fixed electrodes 14 in pair are secured in a male housing 13. A female housing 21 which contains a moving electrode 30 is fitted into the male housing 13, whereupon the moving electrode 30 contacts and straddles the fixed electrodes 14 to make a short circuit. The moving electrode 30 comprises in integral combination retainer pieces 32 that are retained in an electrode retainer tube 22 in the female housing 21, a contact lug 31 that either contacts or detaches from the fixed electrodes 14, and a narrow-width joint 33 that joints the retainer pieces 32 and the contact lug 31 to make an integral unit. The narrow-width joint 33 flexes to deform, thereby absorbing the positional offset that develops when the contact lug 31 comes into engagement with the fixed electrodes 14.

Abstract: To securely lock connectors for charging, a charging connectors 1 is engaged with a vehicle-side connector 25, lock balls 9 are engaged with an engaging groove 28 and a locking member 10 is engaged with the lock balls 9. As a result, the connectors 1 and 25 are locked. Since the connectors 1 and 25 are locked by a ball lock mechanism taking advantage of the engagement of the lock balls 9, the connectors can be more securely locked even if the connectors and wires are heavy as compared to a prior art locking mechanism adopting an elastically deformable resin lance or engaging member and, therefore, a better reliability can be ensured.

Abstract: A breaker device excellent in safety and contained in a compact casing. In a casing 1, a pair of fixed electrodes 11a, 11b is projected, and a movable electrode 31, which is fitted with and detached from the fixed electrodes, is arranged. A handle 40 is inclinably supported by a supporting shaft 45. On the top surface of an upper casing 3, a pair of poles 70 is erected, and rectangular solid sliding projections 71 are projected, while guiding grooves 73 are formed in side faces of the handle 40. In each of the guiding grooves 73, an arc-shaped portion allowing the sliding projection 71 to rotate about the supporting shaft 45 is provided at an upper end of a linear portion which allows the sliding projection 71 only to slide therealong. When the movable electrode 31 is inserted with the handle being erected, the sliding projections are guided by the linear portions, while the handle 40, maintained in an erected state, is inserted.

Abstract: A slidable element is provided for easy positioning in a guide slot when a handle is withdrawn. A handle 40 is inclinably provided on a mount body 35 bearing a movable electrode 31 by a support shaft 45. The support shaft 45 is loosely movable with respect to the mount body 35 by being fixed to the handle 40 and being inserted through oblong holes 42 formed in bearing portions 41 of the mount body 35. In order to withdraw the handle 40, it is necessary to position slidable projections 70 at the bottom ends of linear portions 75 of guide slots 74 while the handle 40 is pulled up. Since the support shaft 45 is movable upward within the oblong holes 42, the handle 40 can singly be pulled up while the movable electrode 31 is still engaged with the fixed electrodes 11a, 11b. During this time, the slidable projections 70 can be positioned and passed through the linear portions 75 of the guide slots 74 with a small force.

Abstract: A breaker device is provided to prevent an insufficient engagement of electrodes. The device, according to the invention, is excellent in safety because of its construction in which a conductive path is located inside the casing 1 and is allowed to have a compact configuration of particularly low height because a handle 40 can be inclined to its resting position. When the handle 40 is inclined to the resting position while a movable electrode 31 is insufficiently engaged, engaging portions 77 come into contact with receiving portions 75 and a lever action works with the contact positions of the engaging portions 77 and the receiving portions 75 as a fulcrum. As a result, a rotating force applied to an operable portion 40A is translated into a downward acting engaging force applied to the movable electrode 31 via rotation center shafts 45 and a mount body 35.

Abstract: A compact breaker device includes a pair of fixed electrodes 11a, 11b are placed upright at one side of the casing 1, and a fuse 12 is accommodated at the other side thereof. A movable electrode 31 including a pair of fittable terminals 32a, 32b connected with each other is mounted on a mount body 35. By engaging and disengaging the fittable terminals 32a, 32b with and from the fixed electrodes 11a, 11b through the ceiling wall of the casing 1, a breaker switch for connect and disconnect the fixed electrodes 11a, 11b is formed. The fuse 12 is connected in series with the breaker switch. A handle 40 is inclinably mounted on the upper surface of the mount body 35. The handle 40 is firmly held in a standing position and a resting position by a spring member 47 provided between it and the mount body 35. The handle 40 is inclined to the resting position when the breaker device is used, while being held upright when the breaker switch is turned on and off.
