Abstract
Abstract The contact apparatus has at least two contact bodies and at least one segmented body. The latter possesses bars separated from each other by slots and having a curved central area. Furthermore, the bars have the form of a three-dimensional curve. In their end areas, the bars possess in each case a section curved in the opposite sense to said curved central area. Besides, the bars are linked together at their ends by means of edge strips. Moreover, the slots extend up to the curved section. In this way, points of contact clearly defined as regards their position and values are assigned to the convexity as well as the end areas of each bar. These measures lead to an improvement of the mechanical and electrical characteristics of the contact apparatus.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
Electric contact apparatus comprising at least one segmented body having a plurality of oblong contact bars, determined by and separated from each other by slots and being arranged side by side in at least one row, said contact bars in their central portion having a shape curved in a plane across the direction defined by said row and being linked together at each one of their ends through a linking strip extending over said row of contact bars, in which said contact bars in at least one of their end ranges adjacent one of said linking strips include a section having a shape curved in a sense opposite to said curved central portion thereof, said linking strip having apertures each extending from the outer edge of the linking strip transverse to the direction defined by said row into the end section of one of said contact bars so as to overlap in a direction transverse to said row with the slots determining said contact bar.
Claim 2
Dependent Claim
165 words
Electric contact apparatus comprising at least one segmented body having a plurality of oblong contact bars, determined by and separated from each other by slots and being arranged side by side in at least one row, said contact bars in their central portion having a shape curved in a plane across the direction defined by said row and being linked together at each one of their ends through a linking strip extending over said row of contact bars, in which said contact bars in at least one of their end ranges adjacent one of said linking strips include a section having a shape curved in a sense opposite to said curved central portion thereof, said linking strip having apertures each extending from the outer edge of the linking strip transverse to the direction defined by said row into the end section of one of said contact bars so as to overlap in a direction transverse to said row with the slots determining said contact bar.
Claim 3
Dependent Claim
28 words
Electric contact apparatus according to claim 1 in which said apertures extend from said outer edge of the linking strip into said curved section of the contact bar.
Claim 4
Dependent Claim
185 words
Electric contact apparatus comprising at least one segmented body having a plurality of oblong contact bars, separated from each other by slots and being arranged side by side in at least one row, said contact bars in their central portion having a shape curved in a plane across the direction defined by said row and being linked together at each one of their ends through a linking strip extending straight over said row of contact bars and substantially parallel to the direction defined by said row, in which at least one of said linking strips includes a section extending along said linking strip and having a cross-sectional profile curved in a direction transverse to the direction defined by said row and in a sense opposite to said curved central portion of said contact bars, said linking strip having apertures each extending from the outer edge of the linking strip transverse to the direction defined by said row into the end section of one of said contact bars so as to overlap in a direction transverse to said row with the slots determining said contact bar.
Claim 5
Dependent Claim
185 words
Electric contact apparatus comprising at least one segmented body having a plurality of oblong contact bars, separated from each other by slots and being arranged side by side in at least one row, said contact bars in their central portion having a shape curved in a plane across the direction defined by said row and being linked together at each one of their ends through a linking strip extending straight over said row of contact bars and substantially parallel to the direction defined by said row, in which at least one of said linking strips includes a section extending along said linking strip and having a cross-sectional profile curved in a direction transverse to the direction defined by said row and in a sense opposite to said curved central portion of said contact bars, said linking strip having apertures each extending from the outer edge of the linking strip transverse to the direction defined by said row into the end section of one of said contact bars so as to overlap in a direction transverse to said row with the slots determining said contact bar.
Claim 6
Dependent Claim
28 words
Electric contact apparatus according to claim 3, in which said apertures extend from said outer edge of the linking strip into said curved section of the linking strip.
Claim 7
Dependent Claim
35 words
Electric contact apparatus according to one of claims 1, 2, 3, or 4, characterized in that, in a horizontal projection, the slots of the segmented body are straight and extend oblique-angled to the linking strip.
Claim 8
Dependent Claim
29 words
Electric contact apparatus according to one of claims 1, 2, 3, or 4, characterized in that the slots of the segmented body have the form of a three-dimensional curve.
Claim 9
Dependent Claim
23 words
Electric contact apparatus according to one of claims 1, 2, 3, or 4, characterized in that the apertures have the form of slots.
Claim 10
Dependent Claim
25 words
Electric contact apparatus according to one of claims 1, 2, 3, or 4, characterized in that the apertures have the form of a gear cutting.
Claim 11
Dependent Claim
41 words
Electric contact apparatus according to one of claims 1, 2, 3, or 4, characterized in that at least one of said linking strips includes an outer longitudinal edge comprising a row of successive projections and recesses having a substantially trapezodial contour.
Claim 12
Dependent Claim
41 words
Electric contact apparatus according to one of claims 1, 2, 3 or 4, characterized in that at least one of said linking strips includes an outer longitudinal edge comprising a row of successive projections and recesses having a substantially triangular contour.
