Abstract: Provided is a novel power conversion device that enables estimation of a temperature of a power device without using a temperature sensing diode and can accurately estimate a temperature and a current of a current sensing element that observes a main current. A measurement voltage (Vref) is applied between source terminals (31s and 49s) of a main control element 31 and a current sensing element 49 in a state in which the main control element 31 and the current sensing element 49 are turned off, and a temperature of a power device 30 is estimated from a current (Ib) flowing between the source terminals (31s and 49s) of the main control element 31 and the current sensing element 49 at the time of the application by using the fact that a resistance value of a semiconductor substrate between the source terminals of the main control element 31 and the current sensing element 49 has temperature dependency.

Abstract: A connector has a male housing (10) with a forwardly open receptacle (11) and a female housing (40) with a terminal accommodating portion (42) that fits into the receptacle (11). A front wall (70) is mounted on a front of the terminal accommodating portion (42) and provides terminal insertion holes (55). Fitting projections (20) are formed on an inner peripheral surface of the receptacle (11), and fitting grooves (60) are formed on an outer peripheral surface of the terminal accommodating portion (42) for receiving the fitting projections (20). Backlash preventing ribs (61) are formed on inner surfaces of the fitting grooves (60) and are squeezed between inner surfaces of the fitting grooves (60) and outer surfaces of the fitting projections (20). The front wall (70) has escaping grooves (80) configured to allow the fitting projections (20) to be passed therethrough with a clearance and inserted into the fitting grooves (60).

Abstract: A lever (4) mounted on a cover (3) is held at a standby position and, in that state, the cover (3) is fitted to a housing (1) in a connecting direction to a position where the cover (3) is not aligned with the housing (1). At this position, gear teeth of the lever (4) and rack teeth of sliders (2) do not interfere with each other and are not engaged. If the cover (3) is subsequently moved in a direction perpendicular to the connecting direction via a guiding action of the engagement of guide receiving portions (9) of the connector housing (1) and U-shaped guide portions (15) formed on the cover (3), the cover (3) is smoothly mounted at a proper mounting position. At this time, since the guide portions (15) vertically sandwich the guide receiving portions (9), upward detachment of the cover (3) is prevented.

Abstract: A retainer (40), a rubber plug (60) and a rubber plug pressing member (70) are mounted in a housing (10). The retainer (40) is movable between a partial locking position and a full locking position, and the rubber plug pressing member (70) is movable between an initial position and a pushed-in position. The rubber plug pressing member (70) is formed with arm portions (74) projecting therefrom. The retainer (40) is formed with unlock linking portions (46) for linking a movement of this retainer (40) from the full locking position to the partial locking position and a movement of the rubber plug pressing member (70) from the pushed-in position to the initial position with each other by coming into sliding contact with the arm portions (74).

Abstract: A wire fixing portion (17) is so formed with a slit (24) as to minimize a tightening diameter at the wire fixing portion (17) by narrowing the slit (24). Thus, there is no likelihood of displacing a fixing band (25) fastened to a middle part of the wire fixing portion (17) toward a side where the tightening diameter is larger. Accordingly, displacements of the fixing band (25) relative to the wire fixing portion (17) are restricted, wherefore displacements of the wires (W) relative to the wire fixing portion (17) are suppressed.

Abstract: A terminal fitting (1, 110, 111, 210) is provided with a wire barrel (4, 131, 231) to be crimped into connection with a core (7, 142, 242) made of a plurality of metal strands and exposed at a leading end portion of a wire (W, 140, 240), and an inner conductive portion (9-12, 134, 135, 235) connected with a wall surface of the terminal fitting (1, 110, 111, 210) and to be held in electrical contact with the metal strands by extending into the inside of the core (7, 142, 242) at an inner side of the wire barrel (4, 131, 231) crimped into connection with the core (7, 142, 242).

Abstract: A door handle device (S) has a handle-side connector (30) fixed to a door handle (10) that is hinged to a handle frame (20). Thus, the door handle device (S) is displaceable as the door handle (10) is turned. A frame-side connector (40) is located in the handle frame (20) and is connectable with the handle-side connector (30) for displacement with the handle-side connector (30) as the door handle (10) is turned. A clamp (60) has a wire retaining portion (61) for retaining a wire group (80) drawn out through an end surface of the frame-side connector (40) and a handle attaching portion (62) continuous with the wire retaining portion (61) for attachment to the door handle (10). Thus, a relative position of the wire retaining portion (61) to the door handle (10) is invariable.

Abstract: A wire cover (1) has a connector-side fixing portion (10) to be fixed to a connector, a wire pressing portion (20) to be held in contact with wires (W), and a connecting portion (30) connecting the connector-side fixing portion (10) and wire pressing portion (20). Resilient engaging pieces (23) project from the wire pressing portion (20) and are formed with engaging holes (25) that can engage engaging projections (42) of a mating member (40) to fix the wire pressing portion (20) to the mating member (40). Catching holes (26) are formed at the leading ends of the resilient engaging pieces (23) and can be caught by a jig (50) inserted from the base side of the resilient engaging piece (23) to displace the resilient engaging piece (23) in a direction to disengage the engaging hole (25) and engaging projection (42).

Abstract: An insertion area for an unlocking jig (D) differs depending on whether unlocking is effected using a first fulcrum portion (22) as a fulcrum or using a second fulcrum portion (27) as a fulcrum. Since this enables an unlocking operation to be carried out by inserting the unlocking jig (D) into the selected one of the different insertion areas, restriction on the insertion area for the unlocking jig (D) can be alleviated and consequently restriction in terms of the arrangement of parts can be alleviated as compared to the case where the insertion area is limited to one spot.
