Embodiment Construction

[0053] figure 1 A specific structure of the flexible flat cable 1 is shown, while Figure 2 to Figure 4 The basic structure of an ultrasonic welder 3 for connecting a flexible flat cable to an element to be connected, such as a busbar 2, is shown. Flexible flat cable 1, such as figure 1 As shown, a conductive element 4 made of copper foil having a thickness of 35 μm is covered by an insulating cover layer 5 made of, for example, PET (polyethylene terephthalate).

[0054] Such as figure 2 As shown, the ultrasonic welding machine 3 has an anvil 6 on which elements to be welded such as busbars 2 are placed, and an arm 7 for compressing the conductive element 4 of the flexible flat cable 1 and Busbar 2 is in contact. Tapering or converging protrusions 8 having a (preferably approximately right-angled) isosceles triangular cross-section are formed on the upper surface of the anvil 6 (the surface facing the bus bar 2 and / or the flexible flat cable 1), while the bus bar 2 On ...

Abstract

A flexible flat cable connecting method includes stripping an insulation coating (5) surface of a flexible flat cable (1) to be connected with a busbar (2) to expose a conductive element (4). The method continues by introducing the flexible flat cable (1) and the busbar (2) between a horn (7) and an anvil (6) of an ultrasonic welding machine (3), and then transmitting an ultrasonic vibration to the horn (7). The horn (7) has a plurality of elongated projections (9) of tapered cross-section pressed in contact with the insulation coating (5) of the flexible flat cable (1). Thus, the elongated projections (9) bite into the insulation coating (5) to weld the conductive element (4) ultrasonically into the busbar (2)

Description

technical field [0001] The invention relates to a method for connecting flexible flat cables with an ultrasonic welding machine and an arm structure of the ultrasonic welding machine. Background technique [0002] In the case of connecting a flexible flat cable to an element to be connected, such as a bus bar, wherein a conductive element, such as a copper foil having a thickness of about Covered with an insulating coating, usually using ultrasonic welding, in which the conductive elements are exposed by peeling off the insulating covering made of, for example, PET to a specified extent; the flexible flat cable and the elements to be connected are introduced into the ultrasonic welding machine between the anvil and the arm, while the exposed surface of the conductive element remains in contact with the upper surface of the element to be connected; ultrasonic vibration is applied to the arm while the flexible flat cable and the element to be connected are compressed, thereby ...
