摘要： PROBLEM TO BE SOLVED: To provide a connection part structure and the connecting method of a multi-core signal cable involving a solderless connector, which can connect a signal cable while confirming the connection of respective wire cores in a hot-line condition. SOLUTION: A branch route is formed in the middle of a signal cable during an operation by a solderless connector 2 and is checked by a continuity test or the like as to whether the branched signal cable and the signal cable during operation are connected properly to each other. After that, the signal cable during operation is cut off, to be replaced by the branched signal cable. After a signal cable wire core 1 is connected by the solderless connector 2 such as this, the solderless connector 2 is disposed in a protective case 22, and a connection part is formed by injecting a resin 23 in the protective case 22.

摘要： PURPOSE:To form Nb3Sn with a good yield without leaving unreacted Nb and to improve critical current of Nb3Sn super conductive wire, by suitably controlling Sn quantity in used bronze, at manufacturing said wire by bronze method. CONSTITUTION:Circumferences of plural cores 1, 1', 1'' made of Nb or Nb alloy having 0.3-5mum diameter are surrounded with a bronze 2 as matrix contg. 12.8-15.0wt% Cu, 0.05-2.0wt% Sn or further one kind among Ti, Zr, Hf, Ta and having 3.1-4.5 bronze ratio exhibited by a formula (1) to obtain a primary element wire 3, and it is wire drawn to hexagonal shape. The plural wires are bundled while aligning, composited together with a barrier material 4 composed of one kind among Ta, Mo, V and the circumferential Cu stabilizing material 5, wire drawn again so that about 1mum Nb core diameter is attained to obtain unreacted bronze method superconductive wire having about 0.3mm diameter. This is heated at 680 deg.C for 5-300hr to completely convert unreacted Nb to Nb3Sn, and superconductive wire having a large critical current density is manufacture.

摘要： PURPOSE:To produce a superconductive wire of a small wire diameter which obviates the rupture and exposure of core materials by forming holes at equal intervals to a billet having a circular section around the central axial line thereof, inserting the core materials into the respective holes and subjecting the billet to extrusion and area reducing working. CONSTITUTION:The three holes 2a... are formed to the billet 1 made of copper, etc. to have the circular section around the central axial line thereof and (number of holes of the inside layer + 6) pieces of holes 2b... are so formed around the same in such a manner that the adjacent holes are equally spaced. The core materials consisting of the composite bars, etc. formed by embedding the many Nb cores into Cu-Sn bronze matrixes are inserted into the respective holes 2a, 2b. The billet 1 inserted with the core materials is then subjected to extrusion, then to area reducing working to form a wire. The wire is subjected to a diffusion heat treatment. The superconductive wire of the small diameter which obviates the disconnection arising from the rupture of the central core material and the exposure of the core materials is obtd. by the above- mentioned treatment.

摘要： PURPOSE:To easily form the ribs to both sides of a stopping lever by mutually engaging a second core pin with a first core pin and forming the ribs to both sides of the stopping lever. CONSTITUTION:In a connector 20, the upper face of a base part end is formed higher by one step and a stopping lever 21 is freely vertically provided to the upper face of the tip part. A first core pin 3 and a second core pin 4 described hereunder are inserted into a forming mold 1 from the right and left directions for the axial center of the opening/closing directions of the mold. The first core pin 3 is provided with the striplike projection pieces 3a, 3a at the prescribed interval. The second core pin 4 is provided with the projection pieces 4a, 4a engaged with the interval of the projection pieces 3a, 3b of the core pin 3. Thereby the ribs 22, 22 can be easily formed to the tip part of the projection pieces 3a, 3b of the first core pin 3 and to the gap of the tip parts of projection pieces 4a, 4a of the second core pin 4.

摘要： PROBLEM TO BE SOLVED: To facilitate operation for fitting a seal ring, by protruding the terminal housing section out of a sheath tip by the region more than halfway around the perimeter to release at least a part of the perimeter from the sheath. SOLUTION: In the water-proof connector, the tip perimeter 1A of a terminal housing section 1 is protruded out of the tip 3A of a sheath section 3 by a part of the tip perimeter, or preferably the region more than halfway around the perimeter. In other words, a part 31 of the sheath 3 is protruded out of the tip 1B of the terminal housing section 1 to protect a locking section 12, but, in most of the sheath section 3, the tip 3A is recessed backward of the tip 1B of the terminal housing section 1. Therefore, the tip perimeter 1A of the terminal housing section 1 is protruded out of the tip 3A of the sheath section 3 by the region more than halfway around the perimeter. In order to protrude at least a part of the tip perimeter 1A out of the tip 3A of the sheath 3, a part of the tip 3A is recessed backward of 1A of the terminal housing section 1 and also the tip perimeter is made longer to protrude out of the tip 3A.
