摘要： PURPOSE:To perform hot-line work easily only through rejoint of connectors by screwing the end section of a branch wire to a branch sleeve and providing a power source connector. CONSTITUTION:A branch sleeve 10 is connected integrally with sleeve members 10a, 10b from the opposite sides of a conductive wire 2 and secured by applying pressure from the outside. A screw hole 11 is made through the side section of the sleeve member 10a and the threaded section 16 of a power source side connector 15 is screwed therein thus providing a power source side connector 15 integral with the branch sleeve 10. The tip of the power source side connector 15 is projected from an insulating member 3 covering the branch section 5 and a protective cover 7 covering the surface of the insulating member 3 and connected with the connector 20 of a feeder line 21 through the projecting section of the power source side connector 15. By such arrangement, it can cope easily with increase of power demand by rejointing a feeder connector having different power conduction capacity.

摘要： PURPOSE:To maintain good contact with a conductive wire and to facilitate joint work by applying pressure around a sleeve thereby pressure jointing a joint integrally with the conductive wire and connecting them electrically. CONSTITUTION:A branch sleeve 10 is pressure jointed to a conductive wire 2. Upper and lower dies 17, 18 are arranged respectively above and below the branch sleeve 10. The dies 17, 18 are supported respectively by upper and lower boards 17a, 18a, where the lower die 18 is moved with respect to the upper die 17 through a hydraulic mechanism (not shown). When the branch sleeve 10 is mounted on the conductive wire 2, two sleeve members 10a, 10b are combined and inserted into the recesses of the upper and lower dies 17, 18 with a screw made of hard material being engaged with the insertion hole 11 of one sleeve member 10a thus providing jointing function of the sleeve member 10 and pressure contacting function with the conductive wire 2. By such arrangement, the conductive wire 2 inserted into the hole of the branch sleeve 10 is compressed and the branch sleeve 10 can be secured while being connected electrically with the conductive wire 2.

摘要： PURPOSE:To cope with the variation of the capacity of feeder line only through rejoint of a connector by providing a source side connector for a branch wire and connecting the feeder line through a load side connector. CONSTITUTION:When a feeder 24 is branched from a main cable 1, a branch line 20 is provided integrally through a branch sleeve 10. When the branch line 20 is connected, insulating member 3 of the main cable 1 is removed to form a stripped section 5 where a conductor 2 is exposed, then the conductor 2 is covered by the stripped section 5 and the branch sleeve 10 is secured. A source side connector 22 is provided at the end of the branch line 20 led out from the main cable 1 through the branch sleeve 10. When a load side connector 23 arranged at the end of the feeder line 24 is connected with the source side connector 22, jointing work of the feeder line 24 with the main cable 1 is facilitated. By such arrangement, it can cope with variation of the capacity of feeder line by simply connecting the feeder line at the side of high capacity load.

摘要： PURPOSE:To make it possible to check up visually a state of loaded power supply and to enable employment of an overcurrent breaker by the same branch circuit, when an electric apparatus is used, by providing an indicting par for indicating the loaded state so that this state can be known. CONSTITUTION:An electric connector 1 is disposed in a place necessitating supply of electricity, e.g. in each room of an intelligent building, so that the electricity can be supplied at any time when it is needed. This connector 1 is equipped with a receptacle 2 and an indicator 3 for indicating a state of loaded current. In a distribution board 4, a loaded current detector 5 is provided and it is connected with the connector 1 disposed in each place where it is needed, by a wiring 6 connected to an overcurrent breaker 6 and by a transmission line 7. Each receptacle 2 and the state of use thereof are detected by the detector 5 in the distribution board 4 through the wiring 6 and a loaded current signal thereof is sent out to the indicator 3 of the connector 1 through the transmission line 7.

摘要： PURPOSE:To reduce mounting area by connecting cabinet panel bodies, which include circuit breakers and switches, between main cables and loads so that their housing frames can be turned with turning mechanisms at the side of the cabinet panel bodies. CONSTITUTION:Main cables 5 supported with cable racks 4 are arranged along the wall of a sectioned room 3 and cabinet panel bodies 1 are installed in front of them. The cabinet panel bodies 1 have hollow rotation shafts 16 rotatably supported by upper and lower rotation shaft bearings 18 on the right of housing frames 17 and turn from the positions shown by the solid lines in the Figure to the positions shown by the broken lines. Branch cables 12 are drawn in from the hollows 23 of the upper bearings 18 and drawn out from the hollows 24 of the lower bearings 18 via primary wiring breakers 8, neutral switches 9, and branch wiring breakers 15. Thereby the sectioned room is made shallower, mounting area is reduced, the shorter branch cables are distributed, and the reliability improves.

摘要： PROBLEM TO BE SOLVED: To provide a clean room structure wherein an opening for maintenance is formed in a clean room for shortening an evacuation route and securing bi-directional evacuation routes without causing the disturbed distribution of an air flow in a room or the agitation of the air flow in a clean room space. SOLUTION: A walking area 5 for workers is provided on the lower side of a floor 2 of the clean room in such a manner that an air flow passing through the floor flows down in the walking area. A stairway 30 or a lifting means is provided for the workers to move up and down between the clean room space 1 and the walking area, and the stairway or the lifting means is partitioned form the walking area with partitioning means 35, 36, 37 having ventilation characteristics. The ventilation characteristics of the partitioning means are set so that the air flow toward the walking area via the opening 33 of the stairway or the lifting means is subjected to air resistance corresponding to the ventilating resistance of the floor.
