Abstract: In an insulation displacement connector including a connector housing, a connector housing rear half portion for receiving slots of contacts is provided on a side more rear than a support portion and an elastic arm in a locking mechanism. Electric wire insertion holes communicating with the slots are opened in a first outer wall surface located at one end of the connector housing rear half portion in a heightwise direction. A portion, corresponding to the slots, of a second outer wall surface opposite to the first outer wall surface is provided as a pressure-receiving wall for receiving an insulation displacement load.

Abstract: Process for production of, from inexpensive raw materials of high commercial availability, N-cyclopropylanilines which are an important intermediate in producing a quinolonecarboxylic acid having a cyclopropyl group at the 1-position, a fluorine atom at the 6-position, and an alkyl group, an alkoxy group or a fluorine-substituted methoxy group at the 8-position (this quinolonecarboxylic acid is a useful synthetic antibacterial agent); and intermediates therefor. For example, a process for producing an N-cyclopropyl-3,4-difluoroaniline represented by the formula (4): ##STR1## includes reacting, in the presence of an acid in an alcohol type solvent, a 3,4-difluoro-2-substituted-aniline with a 1-alkoxy-1-trialkylsilyloxycyclopropane to produce an N-alkoxycyclopropylaniline represented by the general formula (3): ##STR2## and then reducing the N-alkoxycyclopropylaniline.
