Abstract: The connector comprises a connector housing (1) having a plurality of terminals (2) arranged therein and a connector cover (3) removably mounted on said connector housing. Said connector cover has a pressure blade (30) capable of being inserted into an insertion space (24). Said pressure blade (30) of the connector cover (3) is pushed into a completely inserted position within said space (24) so that the pressure blade displaces each terminal (2), thereby resiliently holding flat conductors (38) on said cable (4) between a contact portion (14) of each terminal and said blade (30) and electrically connecting said flat conductors and said contact portions of said terminal. The flexible flat cable (4) is provided with a lock hole (40) between said flat conductors (38) thereon and the connector has a lock plate (15) having a projection (18) on a free and thereof mounted between said terminals (2). In addition, a support blade (34) is mounted at the position under said pressure blade (30) of the connector cover (3). When the flexible flat cable is inserted into said space and the connector cover is pushed deeply into the connector housing (1), said lock hole (40) of the cable becomes engaged with the projection (18) of the lock plate (15). Thus the electrical connector realizes a highly reliable mechanical engagement of the flexible flat cable (4) with the terminals (2) at the completely inserted position. Therefore detachment of the flat cable from the terminals is completely eliminated. In addition, at the insertion start   position, a clearance is present between the contact portion (14) of the terminal (2) and the upper wall (5) of the connector housing (1) so that a low insertion force for the flexible flat cable is also realized.

Abstract: Process for the racemization of an optically active amino acid amide by reacting the amino acid amide with a carboxylic acid in the presence of a solvent, of water and of 0.5-4 equivalents of an aldehyde, calculated relative to the quantity of amino acid amide. Instead of an amino acid amide, the Schiff base of an amino acid amide and an aldehyde can also be used, in which case no extra aldehyde has to be added and the required quantity of water amounts to at least 1 equivalent relative to the quantity of Schiff base. This process gives fast racemization and a high yield of salt of the racemized amino acid amide and the carboxylic acid.
