Capacitor carrier assembly with connection terminals

Abstract

This invention relates to a capacitor carrier assembly with connection terminals. The capacitor carrier assembly includes a carrier, a capacitor disposed within the carrier, and conductive connection terminals. The connection terminals support the carrier relative to another electronic component or device, such as a printed circuit board, holding the various carrier portions in an assembled configuration and providing an electrical connection between the capacitor and the electronic component. Each connection terminal includes a resilient member projecting from a surface of the connection terminal and engaging with the carrier, a serrated region disposed on an opposite edge of the terminal engaging with the carrier, and a flange projecting from the surface in a direction perpendicular to a first surface. The edge of the flange includes an insulation displacement connector (IDC) header for connection to capacitor leads.

Description

Background Technology

[0001] Capacitors used in electronic devices include capacitor leads that are electrically connected to a printed circuit board (PCB) or other electronic components or devices. For example, capacitor leads may be electrically connected to connection terminals located on the PCB. To maintain the electrical connection, the capacitor may be mechanically secured to prevent movement relative to the PCB due to vibration or shock. In some applications, capacitor carriers mounted to the PCB are used to mechanically secure the capacitor relative to the PCB.

[0002] In some electronic devices that use capacitors, tin whiskers may grow near the capacitor leads (e.g., where the leads exit the capacitor casing). Additionally, tin whiskers may grow where the capacitor leads are electrically connected to connection terminals (e.g., at the far end near the capacitor leads). Furthermore, tin whiskers may grow where connection terminals are electrically connected to the PCB. If the tin whiskers become broken, they can form undesirable electrical connections between leads or components on the PCB, such as by creating electrical short circuits. While it is possible to prevent tin whisker growth by applying a coating to the capacitor leads and / or using a soldering process to form certain electrical connections, such preventative measures can be expensive in terms of materials and / or labor.

A first connection terminal is configured to be electrically connected to the first lead, and a second connection terminal is configured to be electrically connected to the second lead. A second end of each of the first and second connection terminals is configured to form an electrical connection with the printed circuit board.

[0025] In some aspects, a capacitor carrier is configured to support a capacitor. The capacitor includes a housing, first capacitor leads, and second capacitor leads. The first and second capacitor leads protrude from one end of the housing. The carrier includes wall structures configured to encapsulate at least a portion of each of the first and second capacitor leads.

[0026] In some embodiments, the carrier includes a conductive first connection terminal and a conductive second connection terminal. Each of the first and second connection terminals is supported by the carrier. The first connection terminal includes: a first body portion configured to be electrically connected to a first capacitor lead at a first connection location; and a first device connection portion protruding from the carrier. The second connection terminal includes: a second body portion configured to be electrically connected to a second capacitor lead at a second connection location; and a second device connection portion protruding from the carrier. The wall structure is configured to provide an encapsulation chamber for at least a portion of encapsulating the capacitor, and the first and second connection locations are located within the encapsulation chamber when the capacitor is disposed in the carrier.

[0027] In some embodiments, the carrier is configured to support the capacitor such that at least a portion of the housing is disposed outside the encapsulation chamber.

[0028] In some embodiments, the encapsulation chamber includes a first region and a second region, the second region being isolated from the first region by at least one of the wall structures, a first connection location being disposed in the first region, and a second connection location being disposed in the second region.

[0029] In some embodiments, the encapsulation chamber includes a third region that is isolated from the first and second regions by at least one of the wall structures. The third region is configured as part of the encapsulated capacitor, the portion including the location where each of the respective first and second capacitor leads exits the capacitor housing.

[0030] In some embodiments, the wall structure includes a first portion and a second portion. The first portion of the carrier's wall structure is arranged to provide a first container portion. The second portion of the carrier's wall structure is arranged to provide a second container portion. The second container portion is configured to be assembled with the first carrier portion such that a capacitor can be disposed between the first container portion and the second container portion.

[0031] In some embodiments, each of the first container portion and the second container portion includes: a semi-cylindrical portion configured to receive and support at least a portion of the housing; and a rectangular prism portion configured to receive at least a portion of the first capacitor lead and the second capacitor lead.

[0032] In some embodiments, the semi-cylindrical portion includes a first side and a second side, the second side being parallel to and spaced apart from the first side. Additionally, the semi-cylindrical portion includes a third side extending between the first and second sides. The third side includes a curved portion configured to partially surround a longitudinal axis perpendicular to the first and second sides.

[0033] In some embodiments, the semi-cylindrical portion includes a separating member that protrudes from the inner surface of the third side. The separating member includes a separating member cutout whose curvature and dimensions correspond to the shape and dimensions of a portion of the housing. The separating member cutout is configured to face that portion of the housing. The separating member of the first container portion cooperates with the separating member of the second container portion to form an inner wall parallel to the first and second sides, and this inner wall is one of the wall structures encapsulating capacitor leads.

[0034] In some embodiments, the rectangular prism portion includes: a first longitudinal wall portion; a second longitudinal wall portion parallel to the first longitudinal wall portion; and a first transverse wall portion. The first transverse wall portion is perpendicular to the first and second longitudinal wall portions and extends between the first and second longitudinal wall portions. The rectangular prism portion includes a second transverse wall portion that is parallel to the first transverse wall portion and extends between the first and second longitudinal wall portions. The rectangular prism portion includes a third longitudinal wall portion that is parallel to the first longitudinal wall portion and extends between the first and second transverse wall portions. The third longitudinal wall portion is disposed between the first and second longitudinal wall portions. Additionally, the rectangular prism portion includes a base plate portion. The first longitudinal wall portion, the second longitudinal wall portion, the first transverse wall portion, and the second transverse wall portion are arranged to form a closed rectangular segment. The base plate portion closes one end of the closed rectangular segment. The rectangular prism portion of the first container portion cooperates with the rectangular prism portion of the second container portion to provide a first encapsulation region for encapsulating a portion of a first capacitor lead and a second encapsulation region for encapsulating a portion of a second capacitor lead, wherein the second encapsulation region is separated from the first encapsulation region by a third longitudinal wall portion.

[0035] In some respects, the capacitor carrier assembly includes the carrier described above and the capacitor disposed in the carrier.

[0036] In some aspects, a capacitor carrier is provided that encapsulates a portion of the capacitor including a junction interface where tin whisker growth can occur. By encapsulating the capacitor including the junction interface where tin whisker growth can occur, tin whiskers present in the device are held within the carrier in an enclosed space, thereby avoiding the risk of electrical short circuits.

[0037] The carrier is configured to securely and mechanically support the capacitor relative to an electronic component or device (such as a PCB) and provide an electrical connection between the capacitor and the electronic device. The carrier is a receptacle comprising: a sidewall; a cover that closes the open end of the sidewall; and a bracket portion that projects from the sidewall and cooperates with the cover to retain the capacitor within the carrier. In some embodiments, the cover is formed separately from the sidewall, and in other embodiments, one edge of the cover is connected to the sidewall via a movable hinge.

[0038] The sidewalls and caps include wall structures that enclose the capacitor leads, thereby preventing contact between the whiskers and the PCB and its components in the event of whisker formation.

[0039] The carrier includes conductive connection terminals for electrically connecting capacitor leads to a PCB. The cover is held in a closed position relative to a sidewall via the connection terminals. In some embodiments, the cover held in the closed position relative to a sidewall via the connection terminals further includes a latch for securing the cover to the sidewall; in other embodiments, the latch may be omitted.

[0040] In some embodiments, the carrier housing is an assembly of two container-shaped housing portions, and these housing portions are identical in shape and size. As a result, a single part can be used for both housing portions, thereby simplifying manufacturing logistics and reducing costs compared to embodiments in which the two housing portions differ.

[0041] In some embodiments, the mating edges of the two container-shaped housings are “shingled,” which allows the carrier housing to expand or contract to accommodate capacitors of various diameters while still enclosing the capacitors within the carrier housing. As used herein, the term “shingled” refers to the edges that provide an acute-angled mating or connection of housing portions such that the edges of the connection overlap when the carrier housing is viewed in a side view.

[0074] refer to Figure 1-5The capacitor carrier assembly 1 mechanically supports the capacitor 2 relative to an electronic component or device (such as PCB 18) and provides an electrical connection between the capacitor 2 and the PCB 18. The capacitor carrier assembly 1 includes a carrier 20 and the capacitor 2 disposed within the carrier 20. Additionally, the capacitor carrier assembly 1 includes conductive connection terminals 80 and support terminals 100. The connection terminals 80 are supported by the carrier 20 and provide an electrical connection between the leads 8 of the capacitor 2 and the contact sockets 19 of the PCB 18. The support terminals 100 are supported by the carrier 20 and, together with the connection terminals 80, mechanically secure the carrier 20 to the PCB 18. The carrier 20 is a housing that receives and holds the capacitor 2 relative to the PCB 18. Furthermore, the carrier 20 includes wall structures that enclose the capacitor leads 8, as discussed further below, thereby preventing contact between the whiskers and the PCB 18 and its components in the event of whisker formation.

[0075] Capacitor 2 may be, for example, an electrolytic radial capacitor. Capacitor 2 includes a capacitor housing 4 having a generally cylindrical shape, comprising a closed first end 5 and an opposing open second end 6. The capacitor housing 4 is elongated along a longitudinal axis 15 perpendicular to the first end 5 and the second end 6, and collinear with the centerline of the housing 4. The second end 6 is plugged by a rubber stopper 7, and the housing 4 is press-fitted around the stopper 7 to form an hermetically sealed area between the housing 4 and the stopper 7. At the press-fitted location, the housing 4 includes an annular region 14, the diameter of which decreases relative to the diameter of the housing 4 at each end 5, 6. The annular region 14 extends around the circumference of the capacitor 2 and is positioned near the second end 6 (e.g., between the second end 6 and the midpoint of the capacitor 2).

[0076] The capacitor 2 includes a pair of capacitor leads 8 that project longitudinally and linearly from a plug 7 disposed in the second end 6 of the housing. Each of the capacitor leads 8 includes: a proximal end 10 corresponding to the position where the capacitor lead 8 exits the capacitor 2; and a distal end 12 opposite to the proximal end and spaced apart from the plug 7.

[0077] Also refer to Figure 6-15 The carrier 20 includes a wall structure 21, which is configured to support and at least partially surround the capacitor 2.

[0078] The wall structure 21 includes sidewalls 23 arranged to form a closed rectangular segment. For this purpose, the sidewall 23 includes a first side 24 and a second side 25, the second side 25 being parallel to and spaced apart from the first side 24 and the longitudinal axis 15 of the capacitor. The sidewall 23 includes a third side 26 facing the second end 6 of the capacitor. The third side 26 connects the first side 24 to the second side 25 and is perpendicular to both the first and second sides 24. The sidewall 23 includes a fourth side 27 facing the first end 5 of the capacitor. The fourth side 27 is parallel to and spaced apart from the third side 26 and connects the first side 24 to the second side 25.

[0079] The first side 24 includes a connection terminal opening 36 located near the third side 26 and a support terminal opening 38 located near the fourth side 27. Similarly, the second side 25 includes a connection terminal opening 37 located near the third side 26 and a support terminal opening 39 located near the fourth side 27. Openings 36, 37, 38, and 39 receive and hold the corresponding connection terminal 80 and support terminal 100, as discussed in detail below.

[0080] The sidewall 23 also includes a bracket 33 that projects inwardly from the sidewall 23 and is configured to support the capacitor 2 within the sidewall. The bracket 33 includes: a first bracket portion 33a that projects inwardly from a first sidewall 24; and a second bracket portion 33b that projects inwardly from a second sidewall 25. Figure 9 Although the first bracket portion 33a and the second bracket portion 33b extend toward each other, a gap exists between them. Each of the first bracket portion 33a and the second bracket portion 33b defines a curved, capacitor-facing surface 33c, which is concave and, when in cross-section ( Figure 12 When viewed from within, it has a partially circular outline. More specifically, the shape of the surface 33c facing the capacitor corresponds to the shape and size of a portion of the surface of the capacitor housing 4. When the capacitor 2 is placed in, as shown in... Figure 2 When the capacitor 2 is placed in the carrier 20 as shown, it is mounted on the bracket 33 and surrounded by the first side 24, the second side 25, the third side 26 and the fourth side 27.

[0081] In addition to the sidewall 23, the wall structure 21 also includes a cover 40 that selectively closes one end (e.g., the upper end) of the sidewall 23. The cover 40 closes one end of the sidewall 23 and includes a curved portion 48 and a planar portion 49. Figure 2The planar portion 49 of the cover 40 covers the capacitor leads 8 and the base plate member 59a, which will be discussed below. The planar portion 49 includes a pair of elongated openings 43, 44, which are configured to receive and retain the ends of the connection terminals 80, as discussed in detail below. The curved portion 48 of the cover 40 covers the bracket 33 and the capacitor 2 supported thereon. The inward-facing surface 41 of the curved portion 48 is concave, and when in cross-section ( Figure 12 When viewed from within, it has a partially circular outline. More specifically, the shape of the inward-facing surface 41 of the curved portion 48 corresponds to the shape and size of a portion of the surface of the capacitor housing 4. The curved portion 48 also includes cover openings 47, which advantageously allow for visual inspection to determine whether the capacitor 2 is housed in the carrier 20 (even when the cover 40 is closed). In the illustrated embodiment, the cover 40 includes three relatively large cover openings 47. For example, the sum of the three areas defined by the cover openings 47 is at least half the total area of ​​the curved portion 48. Additionally, the curved portion 48 includes an elongated opening 45 at a location covering the first sidewall 24. The opening 45 is configured to receive and retain one end of one of the support terminals 100, as discussed in detail below.

[0082] The movable hinge 34 extends along the rear edge 46 of the cover 40 and connects the rear edge 46 of the cover 40 to the second side 25 of the sidewall 23. Therefore, the cover 40, the movable hinge 34, and the sidewall 23 are integrally formed. In the illustrated embodiment, the movable hinge 34 is a single, continuous hinge extending along the curved portion 48, while the flat portion 49 is hingeless. In other embodiments, the movable hinge 34 may be discontinuous. The movable hinge 34 is thin relative to the thickness of the second sidewall 25 or the cover 40, making the movable hinge 34 easy to fold.

[0083] Wall structure 21 also includes base plate members 59a, 59b and 59c ( Figure 10 These base plate members enclose a portion of the end (e.g., the lower end) of the sidewall 23 opposite to the cover 40. The first base plate member 59a is a planar member located below the cover planar portion 49. The first base plate member 59a extends between the first sidewall 24 and the second sidewall 25, and abuts the third sidewall 26. The second base plate members 59b and 59c are bent to conform to the shape and dimensions of the outer surface of the capacitor 2 and are located below the cover bend portion 48. The second base plate members 59b and 59c extend between the first sidewall 24 and the second sidewall 25. The second base plate member 59b is positioned between the first base plate member 59a and the bracket 33, and supports the second end 6 of the capacitor 2. The third base plate member 59c is positioned between the bracket 33 and the fourth sidewall 27, and supports the first end 5 of the capacitor 2.

[0084] The wall structure 21 also includes a first separation member 29 and a second separation member 42. Figure 1 and Figure 11 The first and second separating members are configured to engage the capacitor housing 4 along the annular region 14, thereby holding the capacitor 2 in a desired longitudinal position relative to the capacitor carrier 20.

[0085] Specifically, the first separating member 29 protrudes from the second base plate member 59b toward the cover 40. The first separating member 29 is in the form of a planar wall parallel to the third side 26 and the fourth side 27 of the side wall. The fixed edge of the first separating member 29 abuts the first side 24 of the side wall, the second base plate member 59b, and the second side 25 of the side wall. The first separating member 29 includes a free edge 29a facing the cover 40, and the free edge 29a includes a curved first cut 29b. The shape and size of the first cut 29b correspond to the shape and size of the capacitor annular region 14.

[0086] The second separating member 42 protrudes from the curved portion 48 of the cover 40 toward the second base plate member 59. The second separating member 42 is in the form of a planar wall parallel to the third side 26 and the fourth side 27 of the side wall. The fixed edge of the second separating member 42 abuts the inner surface of the curved portion 48 of the cover. The second separating member 42 includes a free edge 42a facing the second base plate member 59b, and the free edge 42a includes a curved second cut 42b. The shape and size of the second cut 42b correspond to the shape and size of the capacitor annular region 14.

[0087] The first cut 29b and the second cut 42b are received within the annular region 14 of the capacitor and extend together along approximately the entire circumference of the capacitor 2 within the annular region 14. With this configuration, the first separating member 29 and the second separating member 42 cooperate to form an inner wall 32 that tightly surrounds the capacitor 2 within the annular region 14. As a result, the capacitor 2 is held in a desired longitudinal position relative to the third sidewall 26 and the fourth sidewall 27. Furthermore, any whiskers formed at the proximal end 10 of the capacitor lead 8 are held between the inner wall 32 and the third sidewall 26.

[0088] Wall structure 21 also includes T-shaped lead wire support wall 52 ( Figure 1 and Figure 9 The T-shaped lead wire support wall protrudes from the first base plate member 59a and is positioned within the carrier 20 between the inner wall 32 and the third side 26 of the side wall 23. A small gap exists between the upper edge of the lead wire support wall 52 and the planar portion 49 of the cover 40. As used herein, references to directions such as up, down, top, bottom, above, below, above, below, etc., are about... Figure 2 The orientation of the capacitor carrier assembly 1 shown is determined by this. It should be understood that the capacitor carrier assembly 1 is not limited to the orientation shown. Figure 2 The orientation shown is adopted.

[0089] The lead support wall 52 has a transverse portion 54 parallel to the third sidewall 26 and the fourth sidewall 27. Small gaps exist between the lateral ends of the transverse portion 54 and the corresponding first sidewall 24 and second sidewall 25. Additionally, the lead support wall 52 has a longitudinal portion 53 parallel to the first sidewall 24 and the second sidewall 25 and extending between the third sidewall 26 and the transverse portion 54. The longitudinal portion 53 abuts the transverse portion 54 at its midpoint and the third sidewall 26 at its midpoint. The transverse portion 54 of the lead support wall 52 faces the second end 6 of the capacitor and includes a first lead receiving cutout 55 and a second lead receiving cutout 56 open along the upper edge of the transverse portion 54. The first lead receiving cutout 55 is disposed between the longitudinal portion 53 and the first sidewall 24, and the second lead receiving cutout 56 is disposed between the longitudinal portion 53 and the second sidewall 25. When the capacitor 2 is placed in the carrier 20, the first extension of the capacitor lead 8 passes through the first lead receiving cutout 55, and the second extension of the capacitor lead 8 passes through the second lead receiving cutout 56.

[0090] With this configuration, the proximal end 10 of the capacitor lead 8 is positioned on the side of the lateral portion 54 opposite to the distal end 12. Additionally, the connection terminal 80 is positioned on the opposite side of the lateral portion 54 of the lead support wall 52. The proximal end 10 and the distal end 12 of the capacitor lead (including the location where the capacitor lead 8 connects to the connection terminal 80 (e.g., the connection location)) are enclosed in a closed internal space, hereinafter referred to as the encapsulation chamber 50. The encapsulation chamber 50 is defined between the inner wall 32 and the third side wall 26, between the portion of the first side wall 24 and the second side wall 25 adjacent to the third side 26, and between the first base plate member 59a and the cover plane portion 49.

[0091] The encapsulation chamber 50 is configured to hold any whiskers that may form on the capacitor leads 8, thereby preventing contact between the whiskers and the PCB 18 and its components. Furthermore, the encapsulation chamber 50 (which includes the lateral portion 54 of the lead support wall 52) isolates the locations where the capacitor leads 8 are connected to the connection terminals 80 from the lead proximal ends 10. Further, the encapsulation chamber 50 (which includes the longitudinal portion 53 of the lead support wall 52) isolates the locations where the capacitor leads 8 are connected to the connection terminals 80 from each other. Isolating the locations where the capacitor leads 8 are connected to the connection terminals 80 from the lead proximal ends 10 and from each other prevents whiskers from forming electrical short circuits between the capacitor leads 8.

[0092] refer to Figure 5 and Figure 16The capacitor carrier assembly 1 includes a pair of conductive connecting terminals 80 and a pair of conductive supporting terminals 100. The connecting terminals 80 and the supporting terminals 100 mechanically secure the carrier 20 to the PCB 18. Additionally, the connecting terminals 80 electrically connect the capacitor leads 8 to the PCB contact socket 19. Furthermore, one of the supporting terminals 100 and the connecting terminals 80 mechanically secure the cover 40 to the sidewall 23. The connecting terminals 80 and the supporting terminals 100 will now be described in detail.

[0093] At a position near the second terminal 6 of the capacitor and the capacitor lead 8, the connecting terminal 80 is press-fitted into the connecting terminal openings 36 and 37 provided in the carrier 20.

[0094] Each connection terminal 80 is a conductive sheet comprising a first end 81, a second end 82 opposite to the first end 81, and a midpoint 78 disposed between the first end 81 and the second end 82. Each connection terminal 80 includes a first side edge 90 extending between the first end 81 and the second end 82; and a second side edge 91 parallel to the first side edge 90 and extending between the first end 81 and the second end 82. The connection terminal 80 is elongated such that the distance between the first side edge 90 and the second side edge 91 is less than the distance between the first end 81 and the second end 82. Each connection terminal 80 includes a first surface 93 and a second surface 94 opposite to the first surface 93. The first surface 93 and the second surface 94 are defined by the first end 81, the second end 82, the first side edge 90, and the second side edge 91.

[0095] The second end 82 of the connection terminal includes a plug 89 configured to be press-fitted into a conductive receptacle. In the illustrated embodiment, the second end 82 of the connection terminal includes a pair of plugs 89 arranged side-by-side and configured to be received in a contact receptacle 19 of the PCB 18. In use, the plugs 89 provide electrical and mechanical connections between the connection terminal 80 and the PCB 18.

[0096] Each connecting terminal 80 includes a first side edge 90 and a second side edge 91 comprising a serrated region 98. Specifically, the serrated region 98 is disposed on each of the first side edge 90 and the second side edge 91 at a location between the first end 81 and the midpoint 78. The serrated region 98 includes a series of closely spaced protruding ridges 74, wherein each ridge 74 terminates in a apex 76.

[0097] Each connection terminal 80 includes a cover retaining portion 83, a PCB connection portion 84, and a body portion 85 disposed between the cover retaining portion 83 and the PCB connection portion 84.

[0098] The connector terminal cover retaining portion 83 includes a first end 81 of the connector terminal and a serrated region 98. The cover retaining portion 83 is configured to be received and held within corresponding openings 43, 44 in the cover 40, as discussed further below.

[0099] The PCB connection portion 84 includes a second end 82 of the connection terminal 80, which includes the pair of connector plugs 89 received in the contact socket 19 of the PCB 18.

[0100] The connection terminal body portion 85 extends between the cover retaining portion 83 and the PCB connection portion 84, and includes a flange 92 projecting from the side edge 90 of the connection terminal 80. The flange 92 projects in a direction perpendicular to the second surface 94 (e.g., the capacitor-facing side of the body portion 85). The body portion 85 (except for the flange 92) is coplanar with the cover retaining portion 83 and the PCB connection portion 84, and resides in a plane parallel to the first sidewall 24 and the second sidewall 25.

[0101] Flange 92 provides an Insulation Displacement Connector (IDC) 88 configured to receive and electrically connect to capacitor lead 8. In the illustrated embodiment, IDC 88 is a narrow V-shaped cutout opening upwards, for example, facing carrier cover 40. In use, body portion 85 is electrically connected to capacitor lead 8 at connection location 86 corresponding to the connector between the respective capacitor lead 8 and IDC 88. Since capacitor lead 8 forms an electrical connection to connection terminal 80 via IDC 88, capacitor 2 is electrically connected to PCB 18 via connection terminal 80. Flange 92 (including connection location 86) is housed within encapsulation chamber 50, thereby encapsulating the electrical connection between capacitor lead 8 and connection terminal 80.

[0102] The portion of the body 85 located between the flange 92 and the PCB connection portion 84 is a flat plate, the shape and size of which are suitable for press-fitting into the connection terminal openings 36, 37 provided in the side wall 23 at a position adjacent to the second end 6 of the capacitor, thereby fixing the carrier 20 to the corresponding connection terminal 80.

[0103] The support terminal 100 is a conductive terminal that is press-fitted into the support terminal openings 38 and 39 provided in the side wall 23 at a position adjacent to the first end 5 of the capacitor.

[0104] The support terminal 100 is similar to the connecting terminal 80. For this reason, common elements are referred to by common reference numerals, and descriptions of common elements are not repeated. The support terminal 100 differs from the connecting terminal 80 in that the support terminal 100 does not include the flange 92 or IDC 88. Additionally, the first side edge 90 and the second side edge 91 of the support terminal 300 each include a shoulder 95 corresponding to the widened portion of the body portion 85. The shoulder 95 is positioned between the serrated region 98 and the second end 82 of the support terminal.

[0105] Furthermore, although the support terminal 100 is conductive and the support terminal plug 89 is received in the contact socket 19 of the PCB 18, the support terminal 100 is not electrically connected to the capacitor 2. Therefore, the support terminal 100 provides a mechanical connection between the carrier 20 and the PCB 18, but not an electrical connection between the capacitor 2 and the PCB 18.

[0106] Although the cover 40 is secured to the side wall 23 by two connecting terminals 80 and the foremost support terminal 100, the cover 40 may also include a latch 60. The latch 60 is a supplementary securing feature that ensures the cover 40 remains secured to the side wall 23 regardless of extreme usage conditions (e.g., in applications involving large vibrations or mechanical shocks), thereby allowing the capacitor carrier 20 to function reliably (e.g., holding the capacitor 2 therein and maintaining the electrical connection to the PCB contact socket 19). The latches 60 are located on the side of the carrier 20 opposite the movable hinge 34 and are spaced apart from each other.

[0107] Each latch 60 includes a hook portion 62 and a ring portion 63 that engages the hook portion 62, thereby preventing the cover 40 from pivoting about the movable hinge 34. The hook portion 62 protrudes outward from the outer surface of the first sidewall 24. When the carrier 20 is viewed facing the first sidewall 24, the hook portion 62 has a rectangular profile. The hook portion 62 has an angled outward-facing surface 66. The upper end of the outward-facing surface 66 is flush with the first sidewall 24, and the lower end of the outward-facing surface 66 is spaced apart from the first sidewall 24, thereby giving the hook portion a right-angled triangular profile in cross-section. The lower edge 68 of the hook portion 62 is parallel to the first base plate member 59a and provides an engaging surface for the surface of the ring portion 63. The ring portion 63 is a straight ring that hangs down from the forward-facing surface of the cover 40 and defines a through opening 64. When the cover 40 closes the open end of the sidewall 23, the ring portion 63 covers the first sidewall 24 at the position corresponding to the respective hook portion 62. Additionally, when the cover 40 is closed, the hook portion 62 is received within the through opening 64, and the upward-facing edge 65 of the through opening 64 engages the lower edge 68 of the hook portion 62 along the lower end of the ring portion 63, thereby preventing the cover 40 from pivoting about the movable hinge 34.

[0108] Although carrier 20 is shown as having two latches 60, it should be understood that carrier 20 may include more or fewer latches depending on the needs of a particular application. Furthermore, it is contemplated that there are applications in which latches can be omitted, for example, as shown in the capacitor carrier of the second embodiment described below.

[0109] refer to Figure 17-32 The capacitor carrier assembly 201 in the alternative embodiment includes a carrier 220 and a capacitor 2 disposed in the carrier 220. Additionally, the capacitor carrier assembly 201 includes a connection terminal 280 and a support terminal 300 in the alternative embodiment. Figure 17-32 The capacitor carrier assembly 201 shown is related to the above description. Figure 1-16 The capacitor carrier assembly 1 described herein is similar in that the connecting terminal 280 is supported by the carrier 220 and provides an electrical connection between the lead 8 of the capacitor 2 and the contact socket 19 of an electronic component or device (such as PCB 18). The support terminal 300 is supported by the carrier 20 and, together with the connecting terminal 280, mechanically secures the carrier 220 to the PCB 18. Like the carrier 20, the carrier 220 is a holder that receives and holds the capacitor 2 relative to the PCB 18. Additionally, the carrier 220 includes wall structures that enclose the capacitor lead 8, as discussed further below, thereby preventing contact between the whiskers and the PCB 18 and its components in the event of whisker formation.

[0110] The carrier 220 includes: a first container portion 222(1) configured to receive and support a first portion of the capacitor 2; and a second container portion 222(2) configured to receive and support a second portion of the capacitor 2. The first container portion 222(1) and the second container portion 222(2) are each a half-shell having an open side 227, and when assembled together define an internal space configured to receive and hold the capacitor 2.

[0111] The first container portion 222(1) and the second container portion 222(2) each have the same shape and size, making the first container portion 222(1) and the second container portion 222(2) identical. As compared to, for example, the previously described embodiments, by using two identical parts to provide the carrier 220, manufacturing costs are reduced and parts logistics and assembly are simplified. Since the first container portion 222(1) and the second container portion 222(2) have the same shape and size, only the first container portion 222(1) will be described in detail, and it will be referred to as "container portion 222".

[0112] The container portion 222 includes a wall structure 221 that provides: a semi-cylindrical portion 204 whose shape and size are adapted to receive and support a portion of the capacitor housing 4; and a rectangular prism portion 206 whose shape and size are adapted to receive a first capacitor lead and a second capacitor lead.

[0113] The wall structure 221 providing the semi-cylindrical portion 204 forms a hollow structure having a generally semi-cylindrical shape. Specifically, the wall structure 221 providing the semi-cylindrical portion 204 defines half of a cylinder, wherein the cylinder has been cut in half along its height direction. As a result, the wall structure 221 includes: a generally planar first side 224; a generally planar second side 225 parallel to and spaced apart from the first side 224; and a third side 226 extending between the first side 224 and the second side 225. The third side 226 is curved to partially surround the longitudinal axis 234 of the container portion, which is parallel to the height direction of the cylinder and perpendicular to the first side 224 and the second side 225.

[0114] When capacitor 2 is placed in carrier 220, the corresponding inner surfaces 224a, 225a, and 226a of the first side 224, the second side 225, and the third side 226 face capacitor 2. The corresponding outer surfaces 225b and 226b of the second side 225 and the third side 226 define portions of the outer surface of the container portion 222. The first side 224 shares similarities with the rectangular prism portion 206, thereby forming part of the encapsulation chamber 250, as discussed below.

[0115] The first side 224 has a free or exposed first edge 261, and the second side 225 has a free or exposed second edge 262. The curved third side 226 has a free or exposed third edge 263 and a free or exposed fourth edge 264, which are parallel to and spaced apart from the third edge 263. When the container portion 222 is viewed facing the open side 227, the corresponding first edges 261, second edges 262, third edges 263, and fourth edges 264 of the semi-cylindrical portion 204 together form a rectangular profile. The first edges 261, third edges 263, and fourth edges 264 form acute angles with respect to the corresponding inner and outer surfaces 224a, 224b, 225a and 225b, 226a and 226b of the corresponding first side 224, second side 225, and third side 226. In addition, the third edges 263 and fourth edges 264 are parallel to each other.

[0116] The inner surface 226a of the curved third side 226 provides a bracket 233, which is configured to support the capacitor 2 within the sidewall. When viewed in cross-section, the bracket 233 has a partially circular profile. Figure 26More specifically, the shape of the bracket 233 corresponds to the shape and size of a portion of the surface of the capacitor housing 4.

[0117] In some embodiments, the bracket 233 may include a deformable capacitor support structure that prevents the capacitor 2 from moving within the carrier during use under conditions of vibration and / or shock. For example, in the illustrated embodiment, the bracket 233 includes two circumferentially spaced crush ribs 233a that project radially inward from the third side inner surface 226. Figure 21 , Figure 22 The compression ribs 233a have a generally triangular profile, and the apex of each compression rib 233a is configured to compress or deform to accommodate capacitors of different diameters. As an alternative to using compression ribs 233a, the bracket 233 may include a resilient spring feature (not shown) that protrudes inward from the inner surface 226a of the third side and resiliently accommodates capacitors of different diameters.

[0118] When capacitor 2 is placed in such a position Figure 18 When the capacitor 2 is placed in the carrier 220 as shown, it is mounted on the bracket 233 and partially surrounded by the first side 224, the second side 225, the third side 226 and encircled by their respective edges 261, 262, 263, 264.

[0119] The outer surface 226b of the third side 226 is truncated to provide a flat portion 218 parallel to the open side 227. The third side 226 also includes a single container opening 247 disposed on the flat portion 218. The container opening 247 advantageously allows for visual inspection to determine whether the capacitor 2 is disposed in the carrier 220.

[0120] The wall structure 221 providing the semi-cylindrical portion 204 includes a separating member 229 configured to engage the capacitor housing 4 along the annular region 14, thereby holding the capacitor 2 in a desired longitudinal position relative to the capacitor carrier 20. Specifically, the separating member 229 protrudes from the inner surface 226a of the third side 226 towards the open side 227 in a direction perpendicular to the inner surface 226a of the third side. The separating member 229 is parallel to the first side 224 and the second side 225 and includes a free edge 229a facing the open side 227. The free edge 229a includes a curved (semi-circular) separating member cutout 229b. The shape and size of the separating member cutout 229b correspond to the shape and size of a portion of the circumference of the housing 4. Specifically, the shape and size of the separating member cutout 229b correspond to the shape and size of a portion of the circumference of the annular region 14 of the capacitor.

[0121] The wall structure 221 providing the rectangular prism portion 206 includes four sidewall portions arranged to form a frame (e.g., a closed rectangular segment). Specifically, the four sidewall portions include: a first transverse portion corresponding to a first side 224 that shares similarities with the semi-cylindrical portion 204; and a planar second transverse portion 251 parallel to the first side 224. The first side 224 and the second transverse portion 251 each extend in a direction transverse to the longitudinal axis 234.

[0122] The four sidewall portions include a planar first longitudinal portion 252 that extends between a first side 224 and a second transverse portion 251 in a direction parallel to the longitudinal axis 234 and is slightly inward relative to a third edge 263. Additionally, the four sidewall portions include a planar second longitudinal portion 253 that extends between the first side 224 and the second transverse portion 251 in a direction parallel to the longitudinal axis 234 and is slightly inward relative to a fourth edge 264. The wall structure 221 providing the rectangular prism portion 206 also includes a planar third longitudinal wall portion 254 that extends between the first side 224 and the second transverse portion 251 in a direction parallel to the longitudinal axis 234 and is positioned between the first longitudinal portion 252 and the second longitudinal portion 253.

[0123] When capacitor 2 is placed in carrier 220, the outer surface 224b of the first side 224, the inner surface 251a of the second transverse portion 251, and the corresponding inner surfaces 252a and 253a of the first longitudinal portion 252 and the second longitudinal portion 253 face capacitor leads 8. When capacitor 2 is placed in carrier 220, a third longitudinal portion 254 is placed between capacitor leads 8. The corresponding outer surfaces 252b, 253b, and 251b of the first longitudinal portion 252, the second longitudinal portion 253, and the second transverse portion 251 define portions of the outer surface of container portion 222.

[0124] The wall structure 221 providing the rectangular prism portion 206 includes a base plate member 259 that closes one end of the frame opposite the open side 227. The base plate member 259 is planar and parallel to the open side 227. The periphery of the base plate member 259 is adjacent to each of the first side 224, the second transverse portion 251, the first longitudinal portion 252, and the second longitudinal portion 253.

[0125] The first longitudinal portion 252 has a fifth free or exposed edge 265, the second longitudinal portion 253 has a sixth free or exposed edge 266, and the third longitudinal portion 254 has a seventh free or exposed edge 267. When the container portion 222 is viewed facing the open side 227, the corresponding first edge 261, fifth edge 265, sixth edge 266, and seventh edge 267 of the rectangular prism portion 206 together form a rectangular profile. Each of the fifth edge 265, sixth edge 266, and seventh edge 267 forms an acute angle with respect to the inner and outer surfaces 252a and 252b, 253a and 253b, and 254a and 254b of the corresponding first longitudinal portion 252, second longitudinal portion 253, and third longitudinal portion 254. In addition, the fifth edge 265, sixth edge 266, and seventh edge 267 are parallel to each other.

[0126] The first side 224 (corresponding to the first transverse portion) has a first free or exposed edge 261, and the second transverse portion 251 has an eighth free or exposed edge 268. Furthermore, the first side 224 and the second transverse portion 251 each have a discontinuity in height dimension. As a result, the first portions 261(1), 268(1) of the corresponding first edge 261 and the eighth edge 268 have a first height dimension, and the second portions 261(2), 268(2) of the first edge 261 and the eighth edge 268 have a second height dimension, wherein the height dimension corresponds to the distance of the corresponding edge 261, 268 from the base plate member 259, and wherein the first portions 261(1), 268(1) are the portions closest to the third edge 263, and the second portions 261(2), 268(2) are the portions closest to the fourth edge 264. In the illustrated embodiment, the first portions 261(1), 268(1) are shorter than the second portions 261(2), 268(2).

[0127] Each of the first portions 261(1), 268(1) of the first edge 261 and the eighth edge 268, and the second portions 261(2), 268(2) of the first edge 261 and the eighth edge 268, forms an acute angle with respect to the inner and outer surfaces 224a and 224b, 251a and 251b of the corresponding first side 224 and the second transverse portion 251. The first portion 261(1) of the first edge 261 is parallel to the first portion 268(1) of the eighth edge 268, and the second portion 261(2) of the first edge 261 is parallel to the second portion 268(2) of the eighth edge 268, wherein the angles of the first portions 261(1), 268(1) are opposite to the angles of the second portions 261(2), 268(2).

[0128] The first portion 261(1) and the second portion 261(2) of the first edge 261 each include a curved cutout 270, the shape and size of which are adapted to receive the capacitor lead 8 in a gap-fit ​​manner.

[0129] The first container portion 222(1) and the second container portion 222(2) are assembled together such that the free edges of the first container portion face the corresponding free edges of the second container portion 222(2). Specifically, the first edge 261 of the first container portion 222(1) is adjacent to and parallel to the first edge 261 of the second container portion 222(2), the second edge 262 of the first container portion 222(1) faces and is parallel to the second edge 262 of the second container portion 222(2), the third edge 263 of the first container portion 222(1) is adjacent to and parallel to the fourth edge 264 of the second container portion 222(2), and the fourth edge 264 of the first container portion 222(1) is adjacent to and parallel to the third edge 263 of the second container portion 222(2). The fifth edge 265 of the first container portion 222(1) is adjacent to and parallel to the sixth edge 266 of the second container portion 222(2), the sixth edge 266 of the first container portion 222(1) is adjacent to and parallel to the fifth edge 265 of the second container portion 222(2), the seventh edge 267 of the first container portion 222(1) is adjacent to and parallel to the seventh edge 267 of the second container portion 222(2), and the eighth edge 268 of the first container portion 222(1) is adjacent to and parallel to the eighth edge 268 of the second container portion 222(2). As a result, when the first container portion 222(1) and the second container portion 222(2) are assembled together, each of the connecting edges 261, 263, 264, 265, 266, 267, and 268 is “shingled” such that when viewed along a plane 235 including the open side 227 (e.g., from a point in that plane), the connecting edges 261, 263, 264, 265, 266, 267, and 268 overlap. Because each of the connecting edges 261, 263, 264, 265, 266, 267, and 268 is shingled, the carrier 220 can be expanded to accommodate capacitors 2 of various sizes while still enclosing the capacitors 2.

[0130] refer to Figure 17-18 , Figure 22 and Figure 32When the first container portion 222(1) and the second container portion 222(2) are in the assembled configuration, the corresponding semi-cylindrical portion 204 of each of the first container portion 222(1) and the second container portion 222(2) cooperates to provide a cylindrical chamber for receiving the capacitor housing 4. The separating member 229 of the first container portion 222(1) cooperates with the separating member 229 of the second container portion 222(2) to form an inner wall 232. In addition, the separating member cutout 229b of the first container portion 222(1) and the separating member cutout 229b of the second container portion 222(2) are received within the annular region 14 of the capacitor and extend approximately along the entire circumference of the capacitor 2 within the annular region 14. With this configuration, the respective separating members 229 of the first container portion 222(1) and the second container portion 222(2) cooperate to tightly surround the capacitor 2 within the annular region 14, and the capacitor 2 is held in a desired longitudinal position relative to the carrier 220.

[0131] The proximal end 10 and distal end 12 of the capacitor lead 8 (including the connection position 32 where the capacitor lead 8 connects to the connection terminal 280) are enclosed in a closed internal space, hereinafter referred to as the encapsulation chamber 250. The encapsulation chamber 250 is defined between the inner wall 232 and the second transverse portion 251, between the first longitudinal portion 252 and the second longitudinal portion 253, and between the corresponding base plate members 259 of the first container portion 222(1) and the second container portion 222(2).

[0132] Encapsulation chamber 250 is configured to retain any whiskers that may form on capacitor leads 8, thereby preventing contact between the whiskers and PCB 18 and its components. Furthermore, encapsulation chamber 250 is isolated into three separate encapsulation regions 241, 242, and 243, which separate the corresponding connection locations 86 of capacitor leads 8 from each other and from the proximal ends 10 of capacitor leads 8. Specifically, encapsulation chamber 250 includes a first region 241 defined between corresponding portions of the inner wall 232, the first side 224, and the third side 226. The first region 241 encapsulates the proximal end 10 of each capacitor lead 8. Encapsulation chamber 250 includes a second region 242 defined between the first side 224, the second lateral portion 251, the first longitudinal portion 252, the third longitudinal portion 254, and the corresponding base plate members 259 of the first container portion 222(1) and the second container portion 222(2). The second zone 242 encapsulates the connection position 86 and distal end 12 of one of the capacitor leads 8. Additionally, the encapsulation chamber 250 includes a third zone 243 defined between a first side 244, a second lateral portion 251, a first longitudinal portion 252, a third longitudinal portion 254, and corresponding base plate members 259 of the first container portion 222(1) and the second container portion 222(2). The third zone 243 encapsulates the connection position 86 and distal end 12 of the other capacitor lead 8.

[0133] Each of the first container portion 222(1) and the second container portion 222(2) includes connection terminal openings 236, 237 configured to receive and retain a corresponding connection terminal 280. The first 236 of the connection terminal openings 236, 237 extends through the base plate member 259 adjacent to the first longitudinal portion 252, and the second 237 of the connection terminal openings 236, 237 extends through the base plate member 259 adjacent to the second longitudinal portion 253.

[0134] Additionally, each of the first container portion 222(1) and the second container portion 222(2) includes support terminal openings 238 and 239 configured to receive and retain a corresponding support terminal 300. The first 238 of the support terminal openings 238 and 239 extends through a first boss 248 disposed on the outer surface 226b of the third side 226. The first boss 248 is located at the intersection of the third free edge 263 and the second side 225. The second 239 of the support terminal openings 238 and 239 extends through a second boss 249 disposed on the outer surface 226b of the third side 226. The second boss 249 is located at the intersection of the fourth free edge 264 and the second side 225.

[0135] With this configuration, when the first container portion 222(1) and the second container portion 222(2) are in the assembled configuration, each of the connection terminal openings 236 and 237 of the first container portion 222(1) is aligned with the corresponding one of the connection terminal openings 236 and 237 of the second container portion 222(2). Similarly, when the first container portion 222(1) and the second container portion 222(2) are in the assembled configuration, each of the support terminal openings 238 and 239 of the first container portion 222(1) is aligned with the corresponding one of the support terminal openings 238 and 239 of the second container portion 222(2).

[0136] In addition to the first container portion 222(1) and the second container portion 222(2) of the carrier 220, the capacitor carrier assembly 201 also includes a connection terminal 280 and a support terminal 300.

[0137] refer to Figure 28 and Figure 29 The connecting terminals 280 are press-fitted into the connecting terminal openings 236 and 237. Each connecting terminal 280 is a conductive sheet, including a first end 281, a second end 282 opposite to the first end 281, and a midpoint 278 disposed between the first end 281 and the second end 282. Each connecting terminal 280 includes a first side edge 290 extending between the first end 281 and the second end 282; and a second side edge 291 parallel to the first side edge 290 and extending between the first end 281 and the second end 282. The connecting terminals 280 are elongated such that the distance between the first side edge 290 and the second side edge 291 is less than the distance between the first end 281 and the second end 282. Each connecting terminal 280 includes a first surface 293 and a second surface 294 opposite to the first surface 293. The first surface 293 and the second surface 294 are defined by the first end 281, the second end 282, the first side edge 290, and the second side edge 291.

[0138] The second end 282 of the connection terminal includes a plug 289 configured to press-fit into a conductive receptacle. In the illustrated embodiment, the second end 282 of the connection terminal includes a pair of plugs 289 arranged side-by-side and configured to be received in a contact receptacle 19 of the PCB 18. In use, the plugs 289 provide electrical and mechanical connections between the connection terminal 280 and the PCB 18.

[0139] Each connecting terminal 280 includes a first serrated region 298 and a second serrated region 299 on its first side edge 290 and second side edge 291. Specifically, the first serrated region 298 is disposed on each of the first side edge 290 and the second side edge 291 at a position between the first end 281 and the midpoint 278. Additionally, the second serrated region 299 is disposed on each of the first side edge 290 and the second side edge 291 at a position between the midpoint 278 and the second end 282. Each serrated region 298, 299 includes a series of closely spaced protruding ridges 274, wherein each ridge 274 terminates in a apex 276.

[0140] Each connection terminal 280 includes a first elastic member 272 and a second elastic member 273 protruding from a first surface 293. Specifically, the first elastic member 272 protrudes from the first surface 293 at a position between the first end 281 and the midpoint 278, such that its side surface is serrated with a first serrated region 298. Additionally, the second elastic member 273 protrudes from the first surface 293 at a position between the midpoint 278 and the second end 282, such that its side surface is serrated with a second serrated region 299. Therefore, each elastic member 272, 273 is spaced apart from the first end 281, the second end 282, the first side edge 290, and the second side edge 291. In the illustrated embodiment, the first elastic member 272 and the second elastic member 273 are generally rectangular leaf springs, which are integrally formed with the connecting terminal 280, for example, by a process including the following steps: cutting a portion of the outline of the elastic members 272, 273 in a stamping step, followed by a deformation step, whereby the distal ends 272a, 273a of each of the elastic members 272, 273 are bent to protrude from the first surface 293.

[0141] Each connection terminal 280 includes a cover retaining portion 283, a PCB connection portion 284, and a body portion 285 disposed between the cover retaining portion 283 and the PCB connection portion 284.

[0142] The connector cover retaining portion 283 includes a first end 281 of the connector and a first serrated region 298. The cover retaining portion 283 is configured to be received and held within the corresponding connector openings 236, 237 of the first container portion 222(1).

[0143] The PCB connection portion 284 includes a second end 282 of the connection terminal 280, which includes the pair of connector plugs 289 received in the contact socket 19 of the PCB 18.

[0144] The connection terminal body portion 285 extends between the cover retaining portion 283 and the PCB connection portion 284, and includes a second serrated region and a flange 292. The flange 292 protrudes from a first side edge 290 of the connection terminal 280. The flange 292 is positioned between a first serrated region 298 and a second serrated region 299, and protrudes in a direction perpendicular to the second surface 294 of the connection terminal 280. That is, the flange 292 protrudes from the capacitor-facing side of the connection terminal 280. In use, the flange 292 is parallel to the second end 6 of the capacitor.

[0145] Flange 292 provides an Insulation Displacement Connector (IDC) 88 configured to receive and electrically connect to capacitor lead 8. In the illustrated embodiment, IDC 88 is a narrow V-shaped cutout opening upwards, for example, open to the container portion open side 227. In use, connection terminal 280 is electrically connected to capacitor lead 8 at connection location 86 corresponding to the connector between the respective capacitor lead 8 and IDC 88. Since capacitor lead 8 forms an electrical connection to connection terminal 280 via IDC 88, capacitor 2 is electrically connected to PCB 18 via connection terminal 280. Flange 292 (which includes connection location 86) is housed in encapsulation chamber 250, thereby encapsulating the electrical connection between capacitor lead 8 and connection terminal 280.

[0146] In use, the first container part 222(1) and the second container part 222(2) are assembled together, as follows: Figure 17 As shown, the connecting terminal 280 is press-fitted into each of the connecting terminal openings 236 and 237 of the first container portion 222(1), such that the first serrated region 298 engages with the inner surface of the connecting terminal openings 236 and 237 of the first container portion 222(1). Additionally, the connecting terminal 280 is press-fitted into the connecting terminal openings 236 and 237 of the second container portion 222(2), such that the first surface 293 and the second surface 294 are parallel to the longitudinal axis 234, and the second serrated region 299 engages with the inner surface of the connecting terminal openings 236 and 237 of the second container portion 222(2).

[0147] Furthermore, the distal tips 272a and 273a of each elastic member 272 and 273 engage with shoulders 236a and 237a on the inner surface of each of the connecting terminal openings 236 and 237. Figure 29 Shoulders 236a and 237a are parallel to the open side 227 and face away from the open side 227. With this configuration, the first elastic member 272 and the second elastic member 273 cooperate to prevent the first container portion 222(1) from separating from the second container portion 222(2) in a direction perpendicular to the open side 227.

[0148] refer to Figure 30 and Figure 31 The support terminal 300 is similar to the connection terminal 280. For this reason, common elements are referred to by common reference numerals, and descriptions of common elements are not repeated. The support terminal 300 differs from the connection terminal 280 in that the support terminal 300 does not include the flange 292 or IDC 88. Instead, each of the first side edge 290 and the second side edge 291 of the support terminal 300 includes a low-profile rectangular protrusion 392. The protrusion 392 is disposed between the first serrated region 298 and the second serrated region 299 and protrudes in a direction parallel to the second surface 294 of the support terminal 300. The protrusion 392 serves as a stop to prevent the support terminal 300 from being over-inserted into the corresponding support terminal openings 238, 239 of the second container portion 222(2).

[0149] Furthermore, although the support terminal 300 is conductive and the support terminal plug 289 is received in the contact socket 19 of the PCB 18, the support terminal 300 is not electrically connected to the capacitor 2. Therefore, the support terminal 300 provides a mechanical connection between the carrier 220 and the PCB 18, but not an electrical connection between the capacitor 2 and the PCB 18.

[0150] In use, the first container part 222(1) and the second container part 222(2) are assembled together, as follows: Figure 17 As shown, the support terminal 300 is press-fitted into each of the support terminal openings 238 and 239 of the first container portion 222(1), such that the first serrated region 298 engages with the inner surface of the support terminal openings 238 and 239 of the first container portion 222(1). Additionally, the support terminal 300 is press-fitted into the support terminal openings 238 and 239 of the second container portion 222(2), such that the first surface 293 and the second surface 294 are parallel to the longitudinal axis 234, and the second serrated region 299 engages with the inner surface of the support terminal openings 238 and 239 of the second container portion 222(2).

[0151] Furthermore, the distal ends 272a, 273a of each elastic member 272, 273 engage with shoulders 236a, 237a on the inner surface of each of the support terminal openings 238, 239. Figure 31 Shoulders 236a and 237a are parallel to the open side 227 and face away from the open side 227. With this configuration, the first elastic member 272 and the second elastic member 273 cooperate to prevent the first container portion 222(1) from separating from the second container portion 222(2) in a direction perpendicular to the open side 227.

[0152] Therefore, the carrier assembly 1 includes two features that hold the first container portion 222(1) in an assembly configuration with the second container portion 222(2): first, each of the connecting terminal 280 and the support terminal 300 mechanically engages both the first container portion 222(1) and the second container portion 222(2) via a first serrated region 298 and a second serrated region 299; and second, each of the connecting terminal 280 and the support terminal 300 mechanically engages both the first container portion 222(1) and the second container portion 222(2) via elastic members 272, 273.

[0153] In the illustrated embodiment, the capacitor carrier assembly mechanically supports the capacitor 2 relative to the PCB 18 and provides an electrical connection between the capacitor 2 and the PCB 18. It should be understood that the capacitor carrier assembly can support the capacitor 2 relative to other electronic components or devices and is not limited to use with a PCB.

[0154] The foregoing has described selective illustrative embodiments of the capacitor carrier assembly in considerable detail. It should be understood that only structures deemed necessary for illustrating the capacitor carrier assembly have been described herein. Other conventional structures, as well as those in the appendages and auxiliary components of the capacitor carrier assembly, are assumed to be known and understood by those skilled in the art. Furthermore, although working examples of the capacitor carrier assembly have been described above, the capacitor carrier assembly is not limited to the working examples described above, and various design changes may be implemented without departing from the capacitor carrier assembly as set forth in the claims.
