Abstract
A method and device for making multiple connections between electrical conductors surrounded by external insulators in overlapping flexible cables by ultrasonic welding. Overlapping conductors to be connected are arranged on a surface of a carrier disposed between a sonotrode and an electrode, the sonotrode and electrode are sequentially aligned the with overlapping points to be welded, and the conductors are ultrasonically welded at each of the overlapping points. The carrier either includes the electrode at least in designated areas, or includes penetrations constructed and arranged to receive an electrode in designated areas.
Claims25
A method for making multiple connections between electrical conductors surrounded by external insulators in overlapping flexible cables by ultrasonic welding, comprising the steps of:
- arranging a plurality of said flexible cables overlapping at a plurality of points at which conductors are to be welded on a surface of a carrier disposed between a sonotrode and an electrode,
- performing relative movement between the sonotrode and carrier so as to sequentially align the sonotrode and electrode with each of the overlapping points to be welded, and
- ultrasonically welding the conductors at each of the overlapping points to be welded,
- wherein the carrier either comprises the electrode at least in designated areas, or comprises penetrations constructed and arranged to receive an electrode in designated areas.
Device for connection of electrical conductors surrounded by external insulators in overlapping flexible cables by ultrasonic welding, comprising:
- a carrier having a surface on which a plurality of flexible cables having conductors are arranged in overlapping manner at a plurality of points at which the conductors are to be welded,
- a sonotrode for generating ultrasonic oscillations for welding of the conductors relatively movable along the surface of the carrier,
- an electrode associated with the sonotrode, positioned such that an area to be welded is disposed between the sonotrode and the electrode, and
- means for moving at least one of the sonotrode and carrier in order to sequentially align each of the points to be welded with the sonotrode and electrode,
- wherein the carrier either has penetrations constructed and arranged to receive an electrode, or comprises the electrode, at least in defined areas.
