Embodiment Construction

[0037] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numerals refer to like elements throughout.

[0038] As noted above, one problem associated with conventional techniques for resistance welding multi-strand cables 10 to much smaller diameter individual wires 20 is that it is difficult to maintain the position of thinner wires 20 during welding, as Figure 7 shown. In addition, due to the large diameter difference, the contact surface with the corresponding positive and negative welding electrodes is also different, such as Figure 7 indicated by the m...

Abstract

An apparatus for compact wire embedding welding of electrical wires is provided having a set of pre-welding electrodes (100) for pre-forming, via compression, a cross-section of a first wire segment (110) to have a pre-welding shape, the pre-welding shape comprising a recess (115) for a second wire segment (120) to be welded. Furthermore, the apparatus comprises a set of welding electrodes (200) for loading the preformed first segment and the second segment of wire located in the recess and allowing the preformed cross-section of the first segment to be changed to a welding shape adapted to apply a welding current adapted to weld the first segment and the second segment, and a uniform distribution of the welding current density is achieved at the contact surface between the first section and the second section. A method of compact wire embedding welding using the pre-welding electrode (100) and / or the welding electrode (200A) is also provided.

Description

technical field [0001] The present invention relates to resistance welding of cables and / or wires, and more particularly to apparatus and methods for forming joints by resistance welding between wires of different cross-sections and / or made of different materials, such as in multi-strand cables and solid between core wires. Background technique [0002] Resistance welding is commonly used in a wide variety of applications to electrically interconnect wires and / or wires. In particular, cables / wires made of different materials or sizes are often interconnected by resistance welding, such as in automotive applications where thin wiring of sensor devices requires thicker cables electrically connected to the vehicle interface. [0003] In conventional resistance welding techniques used to form welded joints, two cables and / or wires are placed in an overlapping fashion between welding electrodes that apply a welding current sufficient to generate heat in the overlapping area (see...
