Abstract
The bushing includes a plurality of electrically conductive elements and at least one ultrasonic welding joint. The at least one ultrasonic welding joint is formed between one electrically conductive element and another electrically conductive element and mechanically and electrically connects the electrically conductive elements with each other.
Claims9
A bushing comprising:
- a plurality of electrically conductive elements,
- at least one ultrasonic welding joint formed between and mechanically and electrically connecting one electrically conductive element and another electrically conductive element,
- wherein the other conductive element is a metal braid, a section of the metal braid adjoining the ultrasonic welding joint is a solidified section in which the threads of the metal braid are connected to each other in a material locking manner.
A method for producing a bushing comprising:
- providing electrically conductive elements,
- ultrasonically welding one of the conductive elements to another one of the conductive elements, wherein
- the other conductive element is a metal braid, wherein before the ultrasonic welding, a section of the metal braid to be ultrasonically welded is solidified by connecting the threads of the metal braid in this section in a material locking manner.
