Abstract: A voltage-dividing circuit 60, which is formed of serially connected voltage-dividing resistors R1, R2, R3, is disposed between the source terminal S of a power MOSFET 15 and the ground. The divided voltage Va at a connecting point A is applied to one of the input terminals of a comparator 62, while the divided voltage Vb at a connecting point B is applied to one of the input terminals of a comparator 64. The other input terminals of the comparators 62, 64 are connected to the connecting line between an external terminal P4, to which an external resistor 12 is connected, and an FET 30.

A cover member for covering the front case member except for the transparent window and covering the periphery of a mating surface between the front case member and the rear case member is further provided.

Abstract: Electric equipment 130 is fitted in an opening 121 from a passenger compartment side (outside) of an interior member 120 so that an electric wire connecting unit 134 of the electric unit 130 can be electrically connected to electric wires 110 disposed on a non-passenger compartment side (inside) of the interior material 120. A main unit (a main portion) 132 and the electric wire connecting unit 134 of the electric equipment 130 are separated from each other, whereby the main unit 132 and the electric wire connecting unit 134 are separated from each other by operating them from the passenger compartment side and main units 132 of the electric equipment are replaced with the electric wire connecting unit 134 connected to the electric wires 110 being left attached to the non-passenger compartment side of an interior unit in replacing electric equipment 130 in an automotive vehicle employing the interior unit.

Abstract: A molding device is provided for the manufacture of a connector. Two mold halves are provided movable relative to one another, which provide molding spaces when the molds are closed for forming the connector housing and a retainer. One mold half includes a space with a core portion for forming a retainer insertion hole in the connector housing, and a retainer forming portion for forming the retainer in a position lateral of the core portion. The mold is also provided with inserting means for inserting the retainer into the insertion hole after the molding of the two pieces.

Abstract: A lever-type electrical connector has first and second matable connector parts and a lever. The lever is rotatably mounted on the first connector part and has an actuator bar at one end, and two spaced side members extending from the actuator bar alongside the side walls of the first connector part. The second connector part has a hood portion for housing the first connector part and the lever in the connected position. Support of the hood portion, in use engage end portions of the lever so that when the actuator bar is depressed from a starting position to a fully depressed position the lever pivots on the supports to lever the first connector part into the hood portion.

Abstract: To judge with certainty whether the condition of attachment of each metal terminal is proper, a method and apparatus are provided in which a thinned distal end portion of a lance check pin having guide portions contacts an inner surface of a lance flexing space. The lance check pin, when inserted into the lance flexing space, is kept in a proper posture by the guide portions. Therefore, misjudgment of the terminal position is avoided.

Abstract: A lever includes regulating projections, whereas guide grooves are formed in outer walls of a male connector housing. If the lever is inserted into the male connector housing with force when the former is mounted on the latter, the regulating projections abut against the bottoms of the guide grooves to stop the entrance of the lever. As a result, erroneous entrance of lever support shafts into cam grooves is avoided.

Abstract: A connector cover for a wire harness includes a main cover composed of a hinged pair of half case bodies and a secondary cover composed of a hinged pair of semicylindrical bodies. The main cover is formed with an opening for affixing to the back of the connector and a circular opening with a circular ridge elongating inside surface for passing the wire extending from the connector when the half case bodies are closed. The secondary cover having both ends opened for taking in the wire harness and is formed with a cylindrical opening with a channel grove extending therearound for passing the wire when the semicylindrical bodies are closed, and is connected to the main cover such that the circular ridge of the main cover fits in the channel groove around the cylindrical opening, in a manner easy to rotate with respect to the main cover.

Abstract: For effecting a terminal insertion operation with respect to a connector in which a retainer is disposed in a completely-retained position before inserting metal terminals, the metal terminal is inserted into a terminal receiving chamber. As a result, the metal terminal abuts against a slanting guide surface formed on the retainer. When the metal terminal is further advanced, an engagement force in the completely-retained position is released, so that the retainer is forced back to a provisionally-retained position where an engagement projection piece is retracted from the terminal receiving chamber. The retainer thus disposed in the provisionally-retained position is again pushed into the completely-retained position, thereby finishing the insertion of the metal terminal.

Abstract: A lock arm is integrally formed on an outer surface of a connector housing of an insertable connector through a support leg and is engaged with a lock projection on a relay connector portion. A pair of protective walls are provided respectively on opposite sides of the lock arm and are spaced from the lock arm. The protective walls are disposed at a region corresponding to a gap between the lock arm and the connector housing. The front end portions of these protective walls are interconnected by a bridge portion. With this arrangement, a wire is prevented from being caught in the gap between the lock arm and the connector housing.

Abstract: This invention relates to a filling grease composition for automobile wire harness connector which comprises a petroleum oil having an initial boiling point of 400.degree. C. or more and a gelling agent having the general formula: ##STR1## wherein R is a divalent aromatic group represented by a member: ##STR2## as essential components, and the content of said gelling agent ranging from 5 to 50% by weight on the basis of the whole composition.

Abstract: An electrical connector, particularly adapted for use in motor vehicles, having an outer wall, a housing cap adapted to cover the front end of the housing, and one or more wire assemblies each having a terminal recess on the inside surface thereof. The assembly is adapted to be inserted into the housing from the rear and the housing has a corresponding number of receiving passages extending longitudinally therethrough. There is a narrowed portion of the passages which forces the assemblies being inserted outwardly against a deflectable arm in the outer wall. When the assembly is completely in place, the narrowed portion fits into the terminal recess, thereby permitting the flexible portion of the outer wall to return to its normal position. Thus, unless the assemblies are fully seated, the housing cap cannot be fitted over the housing, thereby preventing misassembly of the connector.

Abstract: A method of fitting a rubber stopper for a water-proof connector terminal onto an end portion of an electric wire includes the steps of: successively feeding a group of rubber stoppers aligned in a row in a state wherein each of the rubber stoppers has its longitudinal axis extending vertically; transferring each of the rubber stoppers into a stopper housing portion; retaining the electric wire disposed on an imaginary line passing through the center of the stopper housing portion; and press-fitting the wire into the rubber stopper, whereby the rubber stoppers are successively and continuously fitted on the respective wires. Also disclosed is an apparatus which may be suitably employed to carry out the above-described method. The apparatus includes an aligned stopper successively feeding section, a stopper transfer section, a rotary conveyor section, and a wire press-fitting section.

Abstract: A connecting device for ignition cables and a component in motor vehicle ignition system having a plurality of ignition cables with a L-shape hood of elastic materials which is attached to each of the cable terminals, housing of connecting device with hood supporting member for holding the hood in a mating alignment to outside terminals, and a locking member in the housing.
