Patent number: 9865942Abstract: A shield wire for use with a terminal fitting has a ring (7) is fit laterally to an outer cover (4), and a braided wire (3) is folded onto an outer peripheral surface of the ring (7). A hooking edge (9) protrudes over the entire circumference on a front end part of the ring (7). A barrel (15) of an outer conductor terminal (12) is crimped to the folded braided wire (3).

Patent number: 7141919Abstract: A piezoelectric electroacoustic transducer includes a piezoelectric sounding body in which bending vibration is generated by applying an alternating signal between two electrodes, a case housing the piezoelectric sounding body, and a pair of terminals insert-molded in the case. In the piezoelectric electroacoustic transducer, internal connection portions of the pair of terminals are exposed on the inside surface of the side wall portion of the case so as to extend in a direction that is substantially perpendicular relative to the piezoelectric sounding body, and the internal connection portions of the terminals are electrically connected to the electrodes of the piezoelectric sounding body by using conductive adhesive. The internal connection portions of the terminals do not largely extend inside the case and accordingly, the dimensional difference between the case and the piezoelectric sounding body is minimized.Type: GrantFiled: May 12, 2003Date of Patent: November 28, 2006Assignee: Murata Manufacturing Co., Ltd.Inventors: Kazuaki Hamada, Tetsuo Takeshima, Manabu Sumita, Keiichi Kami, Mitsunori Ishimasa

Patent number: 7064276Abstract: A communication cable having a communication wire and an armor including at least two synthetic resin layers, and protects the communication wire in a loose state. The communication wire protecting tube includes at least two synthetic resin layers, and inserts the communication wire in a loose state. The most hard resin layer of the armor has a crosswise or spiral annular groove or cut portion continuous in the longitudinal direction to reach the radially inner face, and the outermost layer of the armor is formed of a protective layer made of a softer resin than the hard resin layer. The adjoining edge portions of the annular groove or the cut portion come, when the communication wire is to be bent, into contact with each other so that it may be prevented from being bent to a predetermined or smaller bend radius.Type: GrantFiled: December 18, 2003Date of Patent: June 20, 2006Assignee: Sumitomo Electric Industries, Ltd.Inventors: Itaru Sakabe, Hisashi Tanji, Toshiaki Kakii, Hiroki Ishikawa, Kazuaki Hamada, Nobuhiro Akasaka
