Title: Cable connecting contact, contact assembly and multi-core cable connector and crimp tool
Inventor: HAGA GORO
IPC: H01R4/18
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To make the contact of a multi-core connector for a cable high in density, and crimp capable wires in the contact high in density with pressure. SOLUTION: A barrel as the wire crimping portion of a contact for a cable connector is formed into a cylindrical barrel 1a. By this constitution, its horizontal width can be made smaller as compared with that of a current open barrel in an upward V shape, and the arrangement interval of each contact can thereby be made smaller by that amount. And since the width and depth of the recessed part of a crimp tool can be made smaller as compared with a current crimp tool which introduces a current barrel opened in a V shape into its recessed part, gradually makes small the width of the barrel so as to perform crimping while the barrel is being arranged in a certain form. The teeth strength of the crimp tool will never be degraded even if the arrangement pitch P of each contact is made smaller.

Title: Subscriber line polarity detection circuit for telephone exchange
Inventor: SUGIMOTO SHIGERU
IPC: H04Q3/42
Filed: 1987-12-24
Abstract: PURPOSE:To decrease mis-detection by connecting a Zener diode to a path of a detection circuit through which a current flows when a subscriber line reaches a negative potential. CONSTITUTION:A Zener diode ZD operated by a prescribed potential difference is connected in series with a parallel circuit comprising the 1st and 2nd diodes D1, D2. One subscriber line L2 is drawn to the ground potential by the 1st diode D1 and when the subscriber line L2 reaches a prescribed negative potential, the Zener diode ZD is activated, a current flows to the 2nd diode D2 to detect the arrival to the prescribed negative potential. When the negative potential is caused due to an error or a fault and the potential difference from the ground potential does not reach the operating voltage of the Zener diode ZD, the current through the 2nd diode D2 is blocked by the Zener diode ZD. Thus, mis-detection is reduced.
