fig1 shows an initial embodiment of an arrangement with a capacitor assembly 3 , a bearing ring 5 and a carrier 1 . the carrier 1 , which is not shown completely in fig1 , has a plurality of circular through - passages 4 that are arranged in rows and columns next to one another . a bearing ring 5 , preferably made of electrically insulating material , is arranged in one of these through - passages 4 , namely the bottom left through - passage 4 shown in fig1 , so that the bearing ring 5 extends through the through - passage 4 ( in the axial direction ) wherein one subsection 6 a of the bearing ring 5 is located in the illustration in front of the through - passage 4 and an additional subsection 6 b is located in the illustration behind the through - passage 4 . using this bearing ring 5 , one preferred arrangement of bearing rings is described that could also be implemented differently . the bearing ring has on its outside circumference in at least one subsection 6 a a plurality of slots 7 located around the circumference . this facilitates the manual installation of the holding connection . as an alternative or in addition to this , a subsection 6 a of the bearing ring 5 is designed so that the subsection 6 a cannot be inserted through the through - passage 4 because the diameter of the subsection 6 a is greater than the inner diameter of the through - passage 4 . it can be seen in fig4 that the material 9 at the end of the subsection 6 a defines a contact surface 10 running around the through - passage 4 and making contact with the material of carrier 1 without being present inside the through - passage 4 . the design of the bearing ring 5 can also be seen in fig2 that depicts the bearing ring 5 alone . the arrangement as per fig1 includes a mounting ring 15 , which cannot be seen in fig1 , that is made of metal for example and that has a plurality of projections 16 tapering to a point at their free end distributed on the radially inner side of the ring around the inner circumference . in this respect , the projections 16 do not extend only radially inward but also in an axial direction . this weir 15 is pressed into a slot 19 ( see fig4 ) in a section 20 of the bearing ring 5 projecting radially inward by inserting additional projections 17 distributed around the circumference of the weir 15 and extending in the axial direction opposite to the direction that the projections 16 extend . next , the bearing ring 5 prepared in this way with the weir 15 on the one hand and the assembly 3 to be held on the other hand are moved in an axial direction relative to one another ( wherein the assembly 3 is inserted inside the bearing ring 5 ) such that the projections 16 dig into the surface of the assembly 3 and the desired axial relative position on the external circumference of the assembly 3 as shown in fig4 . either the bearing ring 5 with the weir 15 it contains is inserted in the through - passage 4 of the carrier 1 before inserting the assembly 3 in the bearing ring 5 or after inserting the assembly 3 . the completely installed arrangement can be seen in the illustration of fig4 . optionally , the subsection 6 b that is moved through the through - passage 4 to reach the completely installed position can also have sections projecting outward that , however , still allow the section 6 b to move through . for example , these sections may allow slight elastic deformation and / or be moved through the through - passage 4 by scraping under radial pressure so that unintended movement of the bearing ring 5 in the opposite direction is hindered or impossible . a second embodiment is shown in the fig5 to 10 . the arrangement has one carrier 31 . a bearing ring 45 extends through the carrier 31 . the held capacitor assembly 3 extends inside the bearing ring 45 through a through - passage 4 in the carrier 31 . in the same manner , the assembly 3 can be mounted at its back end in a second carrier . a clamp ring 36 is provided in the through - passage 4 for the secure and permanent mounting of the assembly 3 but this ring ( as shown in fig6 and 7 ) does not extend into the through - passage 4 . despite this , when installed , it generates a clamping action , that is , forces that act particularly in the radial direction and that hold the assembly 3 to the carrier 31 by means of the clamping action . in this process , the clamping force is transferred from the radial outside to the radial inside first from the carrier to the bearing ring 45 , then from this ring to the clamp ring 36 and then from this ring to the outer surface on the circumference of the assembly 3 . a clamping force is not transferred directly from the bearing ring 45 to the assembly 3 . fig8 depicts an exemplary embodiment of a bearing ring 45 that , with regard to the shape of the outer circumference , may be designed like the bearing ring 5 as per fig2 . particularly , the bearing ring may have a first section 46 a and a second section 46 b wherein only the second section 46 b , but not the first section 46 a , can be inserted through the through - passage 4 of the carrier 31 . even more characteristics described using fig2 or the description of the bearing ring 5 may be present either individually or in any combination with the bearing ring as per fig8 , too . as shown in fig8 , the exterior design , that is , the design on the outside circumference of the bearing ring 45 may deviate from the design of the bearing ring 5 . in particular , this bearing ring has engaging members 48 on the transition section between the first section 46 a and the second section 46 b that project in an axial direction from the first section 46 a . two of these are visible in fig8 . for example , two additional engaging members are located at the same angular intervals around the longitudinal axis on the outer circumference of the bearing ring 45 . the quantity of such projections , however , is not limited to four . rather , one single such projection is sufficient in principle . however , a plurality of such projections may also be provided at different angular intervals . in each case , the inside edge of the through - passages or at least one through - passage of the carrier 31 ( as indicated , for example , by the reference number 39 on carrier 31 in fig5 ) has at least one corresponding notch so that all projections on the bearing ring can fit into one of the notches 39 and , in this way , prevent unintended rotation of the bearing ring about the longitudinal axis running in the axial direction . similar to the bearing ring 5 as per fig2 , sections 49 projecting radially outward may be formed on the outer circumference of the second section 46 b , these sections , for example directed in the axial direction to the first section 46 a , rising from the level of the outer circumference 46 b and having an edge extending in the radial direction on their end adjacent to the first section 46 a . in this respect , the distance of the edge from the first section 46 a is preferably as large as the thickness of the through - passage in the carrier 31 in the axial direction . in this way , the bearing ring 45 , with the free end of the second section 46 b in front , can be inserted through the through - passage 4 until the face area of the first section 46 a makes contact with the material of the carrier 31 . in this case , the projection 49 with its edge prevents the bearing ring 45 from being unintentionally removed from the through - passage again or from moving in an axial direction within the through - passage . another characteristic also explained using the exemplary embodiment as per fig8 just like the other characteristics described before but also present in other embodiments individually or in combination with other characteristics is an internal thread in the portion of the first section 46 a extending from the free end of the bearing ring 45 in the direction of the second section 46 b . the internal thread is identified in fig8 by the reference number 50 . corresponding to the internal thread , the clamp ring 36 shown in fig9 has an external thread on its outer circumference . however , in the exemplary embodiment shown in fig9 , the external thread 51 does not extend to the free end of the clamp ring 36 in the axial direction . rather , the clamp ring 36 has a plurality of ring - shaped segments 54 on this free end that are each separated from the adjacent segments 54 by a notch 55 . as shown in fig1 , one projection 59 of an assembly tool 58 can be inserted into each of these notches 55 . the assembly tool 58 is designed to be circular and has a through - passage 61 in its center area wherein the through - passage 61 is formed by a hexagonal - shaped material to allow , for example , the placement of a wrench . if the assembly tool is used , a contact pin 30 projecting in an axial direction ( also see fig1 , fig5 and fig1 ) extends at least into the through - passage 61 . this contact pin 30 of the capacitor assembly 3 serves as the electrical connection for the assembly 3 . using the assembly tool 58 , the clamp ring 36 can be screwed into the bearing ring 45 in an axial direction whereby members 69 , located on the front end in the axial direction facing the rear end in the axial direction with the segments 54 , said members being tongue - shaped , i . e ., running to a point ( as shown in fig6 and 7 ), are forced between the material of the bearing ring 45 and the assembly 3 , generating the desired clamping action in this manner . in general , not just in the embodiment of the clamp ring shown in fig6 , 7 and 9 , a clamp ring may have at its front end in the axial direction at least one section that tapers in the direction of the free end , in particular , tapers such that the thickness of the free end measured in the radial direction decreases . such a tongue - like design allows generation of the desired clamping action in a simple way . optionally and , for example , as shown in the exemplary embodiment as per fig6 and 7 , the bearing ring can have on its inner circumference a surface section running in an axial longitudinal sectional view obliquely from radially outside to radially inside and , the same time , in the axial direction , the tongue - like free end of the clamp ring moving along this section during its axial motion . such a beveled surface section is identified in fig6 and 7 , for example , using the identification number 64 . in the completely installed position shown in fig7 , the free end of the clamp ring 52 even extends beyond the beveled section of the bearing ring 45 . in the exemplary embodiment shown in fig9 , the tongue - like members 69 are distributed uniformly around the circumference and are in each case separated from one another by a notch 70 around the circumference . in particular , if the plastic material used , for example , undergoes plastic deformation due to the clamping pressure , the notches 70 may be eliminated . another embodiment of a bearing ring and a corresponding arrangement are now described using fig1 and 12 . the bearing ring 85 has two areas 86 a , 86 b located one behind the other in the axial direction . the area 86 b of the bearing ring is inserted in the axial direction through the corresponding through - passage 4 of a carrier 81 until an abutment surface 91 of the first area 86 a contacts the material of the carrier 81 . as can easily be seen particularly in fig1 , the bearing ring 85 has on its inner circumference a plurality of sections 98 projecting linearly in the axial direction . the ends lying inside in the radial direction of these sections 98 are positioned such that a capacitor assembly 3 held by the bearing ring 85 is held by the clamping action of the sections 98 ( also see fig1 ). in addition , the section 86 b immediately in front of the abutment surface 91 around its outer circumference has a plurality of sections 99 projecting radially outward that the bearing ring 85 uses for support by creating a clamping action on the inner edge of a through - passage 4 of the carrier 81 when the bearing ring is installed in the through - passage 4 . both the material of the sections 99 and of the sections 98 may undergo elastic deformation during the creation of the clamping action . on its free end , the section 86 b has sections 92 a , 92 b running radially inward . in the exemplary embodiment , two such sections 92 are formed facing each other on opposite sides in the radial direction . the sections 92 prevent a capacitor mounted in the bearing ring 85 from escaping from the free end of the second section 86 b . in a particular embodiment of the sections 92 , at least one section 92 has a projection 94 on its radially inward edge and this section can move in the axial direction if an appropriate pressing force is applied by the mounted capacitor assembly on the projection 94 . in this respect , the free end of the projection 94 is not under stress if no axial force is being exerted on it in an axial position in front of ( in the illustration of fig1 , below ) the section 92 . for this reason , the capacitor assembly , if it cannot exert the force required to deform the projection 94 or if it can only exert part of this force , can touch only the projection 94 but not the section 92 . depending on the axial force , the capacitor assemblies may be mounted in a different axial position in the bearing ring 85 . for example , fig1 shows a capacitor assembly 3 a on the left that also makes contact with the section 92 while a capacitor assembly 3 b is shown on the right in fig1 that only makes contact with the projections 94 but not the section 92 . in this way , it is possible to implement reliable reverse voltage protection ( that is , protection against connecting the incorrect electrical connections of different capacitor assemblies ). for example , the connector 30 a of the capacitor assembly 3 a is equipped with a projecting contact pin as well as a ring - shaped section 96 having a larger outer diameter than the contact pin 95 . this ring 96 indicates that this involves the terminal post of the first type ( for example , the positive post ). on the other hand , the terminal post 97 of the capacitor shown on the right in fig1 does not have such an additional ring . an electrical terminal post of the other type ( for example , the negative post ) is identified in this way . for example , the capacitors 3 a , 3 b are to be connected in series . to do this , the connecting member 100 illustrated above in fig1 is used and this member has one through - passage for each of the contact pins 95 , 97 . for example , fig1 shows the installed state . as the front , free end of the ring - shaped section 96 is located at a different axial position ( higher , in fig1 ) than the front surface of the capacitor 3 b , the connecting member 100 has two bends in its central area along its length so that while both ends 101 a , 101 b run parallel to one another but are not in the same plane . the bends are identified by the reference numbers 102 a , 102 b . this design of the connecting member 100 also contributes to reverse voltage protection . if the two capacitor assemblies to be connected in series were positioned with the same post next to one another ( for example , the positive post ) differently than shown in fig1 , this situation would be obvious because both posts would have either one ring - shaped section 96 or none at all . when fastening the connecting member 100 with the bent center section to the contact pins ( for example , by screwing nuts onto the outer thread of the contact pins ), the surface of the connecting member 100 would not make contact with as complete a surface as possible either on the front end of the ring - shaped sections or the front end of the assembly housing and would thus be easy to recognize . expressed in other terms , the design with two bends for the connecting members to the axial ends of the assemblies with the opposite circumstances would lead to the situation that the assemblies are brought into an appropriate axial position because of the fastening of the connecting members to the contact posts . if the assemblies are of incorrect polarity , that is , mounted in an inverted position , the surface of at least one of the contact members would not make as complete a surface contact as possible on one of the assemblies . it can be seen in fig1 that the sections 92 of the bearing rings 85 extending inward in the radial direction leave some free space open between them over which the connecting member 100 can extend when installed . it can be seen in fig1 how a capacitor assembly 3 with the help of two bearing rings , for example , of the type of bearing rings that were described using fig1 and fig1 , and with the help of two carriers 81 a , 81 b can be held securely . the carriers 81 have additional through - passages 106 between the through - passages 4 for installing the capacitor assemblies . for example , using stud bolts 107 and nuts 108 , the carriers 81 a , 81 b are screwed to one another so that the assemblies cannot escape unintentionally from the bearing rings 85 . fig1 shows the installed state with a total of four installed capacitor assemblies 3 of which the assemblies above one another are connected electrically to one another on the axial side at the front by means of a connecting member 100 with two bends . in this figure , the connecting members 100 have not yet been screwed tight or fastened in another manner to the front contact surfaces of the assemblies 3 . fig1 shows an axial longitudinal view through an axial end section of a capacitor assembly 3 and a bearing ring 85 arranged in this end section . on the left in the figure can be seen the section 92 extending inward in the radial direction with the projection 94 being slightly offset in the axial direction . in general , it is valid that the projections 94 make it possible for the capacitor assembly to be shifted slightly in the axial direction , in particular if one or more such projections are located on both opposite axial ends of the assembly . for example , the shift in the axial direction , as mentioned , is effected by the connecting members 100 when these are fastened to the contact pins .
