Abstract: A protective structure for junctions consists of a terminal holder including a mount, a plurality of joint terminals arranged on the mount, and a hood which receives one end of the joint terminals; an auxiliary terminal holder including a fixing frame and a plurality of auxiliary terminals arranged on the fixing frame in compliance with the joint terminals; a flat cable held between the terminal holder and the auxiliary terminal holder such that its exposed conductors, the joint terminals and the auxiliary terminals are subjected to welding to provide a junction; a hold-down member fittable to the terminal holder transversely to the flat cable; and a protective cover fittable to the terminal holder to cover a part of the flat cable having been bent back around the hold-down member. Stresses are prevented from directly acting via the flat cable on the junction.

Abstract: A cable holding structure of this invention comprises a groove in which a bending portion of a flexible flat cable is to be inserted, a first opening portion through which the flexible cable extending in the X direction as one direction from the bending portion passes and a second opening portion through which the flexible cable extending in the Y direction as the other direction from the bending portion passes, the first and second opening portions being contained in the groove, and a stopper provided on the first opening portion, which contacts a side edge of the flexible cable extending in the Y direction as the other direction of the bending portion so as to prevent the bending portion from slipping out in the X direction as one direction. Consequently, this prevents a residual stress from being generated in the flexible flat cable thereby improving the service life of the flexible flat cable.
