Abstract
Abstract In order to compress electric conductors (22) like strands by means of ultrasonics and/or weld them together in a joining knot it is suggested that the sonotrode (10) of an ultrasonic welding device has a surface (18) preferably positioned centrally above or below the longitudinal axis of the sonotrode (14), which surface being coordinated with a surface (20) of an anvil (12) for the upper and lower bounding of a compression chamber (24) for the lodging of the conductors (22). The compression chamber (24) is laterally limited by cheeks of which at least one is movably designed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
A device for the joining of electrical conductors such as strands comprising a sonotrode for generating sound vibrations, a counter-electrode serving as an anvil for cooperation with said sonotrode, limiting elements, a compression chamber defined between a portion of said sonotrode and anvil and said limiting elements to receive the electrical conductors, one of said limiting elements lying opposite and spaced from said other limiting element and said sonotrode and said anvil lying opposite one another and spaced from each other to thereby define said compression chamber, one of said limiting elements and one of said sonotrode and anvil of the compression chamber being movably mounted whereby said device is able to accommodate conductors for varying cross-sections.
Claim 2
Independent Claim
117 words
A device for the joining of electrical conductors such as strands comprising a sonotrode for generating sound vibrations, a counter-electrode serving as an anvil for cooperation with said sonotrode, limiting elements, a compression chamber defined between a portion of said sonotrode and anvil and said limiting elements to receive the electrical conductors, one of said limiting elements lying opposite and spaced from said other limiting element and said sonotrode and said anvil lying opposite one another and spaced from each other to thereby define said compression chamber, one of said limiting elements and one of said sonotrode and anvil of the compression chamber being movably mounted whereby said device is able to accommodate conductors for varying cross-sections.
Claim 3
Dependent Claim
51 words
The apparatus as claimed in claim 1 wherein the sonotrode is provided with means for engaging the electrical conductors and said anvil as means complementary to said means for engaging said respective means of said sonotrode and said anvil together defining the upper and lower limiting areas of said compression chamber.
Claim 4
Dependent Claim
41 words
The apparatus as claimed in claim 1 wherein said limiting elements are shaped in the form of cheeks which laterally bound the compression chamber, one of said limiting elements being mounted for movement vertically to the longitudinal axis of said sonotrode.
Claim 5
Dependent Claim
27 words
The apparatus as claimed in claim 1 wherein said compression chamber has a longitudinal axis and is channel-like and extends parallel to the conductors to be joined.
Claim 6
Dependent Claim
19 words
The apparatus as claimed in claim 1 wherein said sonotrode and said anvil have facing surfaces which are concave.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 1, characterized thereby that the distance between the areas defined by the limiting elements can be adjusted according to the thickness of the conductors to be joined.
Claim 8
Dependent Claim
15 words
An apparatus according to claim 1, characterized thereby that the apparatus is a mobile construction.
Claim 9
Dependent Claim
31 words
An apparatus according to claim 1, characterized thereby that the sonotrode generating the sound vibrations, operating together with a booster to amplify amplitudes, is integrated with the booster to a unit.
