Also shown is a power module 12A that is attached by magnetic force, however, the power module 120 can also be attached to the support structure 22 in any desired manner. If it is desired to use more than one support structure 22 in the energy consuming assembly, a jumper device 320 can also be magnetically supported on the support structure 22 to connect one support structure 22 to another adjacent support structure ( Not shown). Energy consuming device 20 can be an LED device. It will be appreciated that the illustrated embodiment is suitable for use in a track lighting application because the energy consuming opening 20 can be easily positioned, installed, and moved back and forth along the support 22 .

—對由殼體38支撐的磁體42a、 42b ;以及一對由殼體38支撐的端子62a、62b。如需照明， 耗能模組40可包括LED陣列（LED陣列可為按所需圖案設置 的一個或多個LED)，但也可為其它耗能裝置，諸如不限制 於無線電設備、照相機、感測器，而且耗能裝置20也可根 據需要通過包含諸如揚聲器'圖像投影儀之類的器件來投 影圖像或發出聲音。可為裝飾性的蓋體46，定位在殼體38 上並遮蓋耗能模組40和磁體42a、42b。如本領域中公知的， 可設置有透鏡或其它光造型元件48，並且能由殼體38和/或 蓋體46支撐，以將來自耗能模組40(如果被設定為LED陣列） 的光加以引導。 殼體38可採用各種形狀，例如如第1圖所示的圓形、如 8 M436129 第2圖所示的矩形、正方形、三角形、橢圓形等。殼體％包 括.一基部50，具有内表面52和外表面54 ; —孔56，穿過 基部50 ;磁體座58a、58b，設置在基部50的每一端並由中 心孔56隔開；以及第一和第二端子孔60a、60b及其相關的 端子62a、62b。應注意的是，儘管示出為雙磁體座，但在 一個貫施例令’殼體38可以另外的方式構造成設置單個磁 體座。例如，但不限於殼體38的一端能經由支撐結構22提 供的唇緣來保持且隨後單個磁體座及相關磁體將足以將殼 體38固定定位。可替代地，一磁體座可位於殼體38上的中 心位置’以使得力均句地分佈於兩端（以及熱橋，如果包含 的話）。耗能模組40的一部分經由孔56延伸穿過基部50。 磁體42a安置在磁體座58a中；磁體42b安置在磁體座 58b中。如所示出的磁體42a、42b橫截面為矩形，以有益於 方便地製造該元件，然而，也可以採用其它各種不同形狀 的磁體42a、42b。各磁體座58a、58b形成為自内表面52延 伸的凹部。各磁體座58a、58b具有：多個側壁64，自内表 面52延伸；以及一介面壁66。各磁體座58a、58b優選與磁 體42a、42b的形狀一致’且磁體42a、42b可如所示出地自 殼體38的内表面52伸出或者與殼體38的内表面52齊平。 蓋體46可採用各種形狀以容納耗能模組40和可選的光 學器件（optic)48。例如但不限於，蓋體46可完全為平的，蓋 體46也可基本上是平的並具有升高的中心部分來容納光學 器件48 ’而且蓋體46也可為凹形或凸形。所示出的蓋體46 包括：一蓋壁68，具有内表面70和外表面72 ; —個孔，穿 9 M436129 過蓋壁68的中心，透鏡或其它光造型元件48安裝於所述孔 中；磁體座74a、74b，設置在蓋壁68的各端並由所述中心 的孔隔開；以及侧壁75a、75b、75c、75d，自蓋壁68的邊 緣延伸。 當蓋體46安置在殼體38上時，磁體42a保持在磁體座 74a中’磁體42b保持在磁體座74b中，並且側壁75a、75b、 75c、75d與殼體38的邊緣配合。各磁體座74a、74b具有自 内表面70延伸出的側壁76，同時内表面70形成所述凹部的 底壁。側壁75b、75d的一部分形成相應磁體座74a、74b的 一部分。然而’可以意識到的是，儘管蓋體46的側壁75b、 75d示出為磁體座74a、74b的一部分，但是也可在蓋體46上 設置單獨的壁，以形成磁體座74a、74b的其餘部分。各磁 體座74a、74b優選與磁體42a、42b的形狀一致。由此，可 以意識到的是，磁體42a、42b被夾在内表面70和介面壁66 之間’且由此被保持定位。另外的約束由側壁76、75b、75d k供’然而’任何可取的約束都是合適的。例如，磁體42a、 42b利用黏接劑或其它緊固系統被附接。將磁體42a、42b保 持在殼體38和蓋體46之間的益處在於能降低製造成本。 如所示出的，耗能模組40被設定為固態照明元件，所 述固態照明元件包括板78，LED陣列安置在板78上並受蓋 體46保護。板78可為熱傳導性材料，諸如覆蓋有絕緣層的 鋁，在所述絕緣層上放置所述LED陣列。可替代地，如果 耗能模組40對熱衰減較不敏感，則板78可為電路板或一些 其它複合結構。熱橋82(其可為但不限於導熱墊或導熱膏) 10 可設置在耗能模組40的外表面（例如在板78的下表面上）。熱 橋82可為熱傳導性黏接墊片，諸如，例如3M導熱膠帶 8810。如所示出的，熱橋82將板78連接到底壁3〇。在所示 出的實施例中，因板78被設定為使板78和所述LED陣列之 間具有較低的熱阻(優選地所述板將具有大於5〇瓦/米-開爾 文((W/(m K))的熱傳導率’且更優選地將具有大K1〇〇w/(m K)的熱傳導率），且熱橋82有效地將板78連接到底壁30，所 述LED陣列和底壁3 0之間的總熱阻將低於3 c /w且優選低於 2C/W。另外，如果使熱橋82保持薄形並選擇具有相對高的 熱傳導率的材料’則可使總熱阻低於1C/W。例如，若採用 普私光電（BRIDGELUX)LED陣列與合適的熱橋組合以及由 磁體42a、42b施加足夠的力，則這種設計就是可行的。由 此，可以意識到的是，所示出的設計一般允許具有非常有 效的熱傳遞设什的磁性支揮耗能裝置2〇，允許使用在亮度 大於500流明的照明裝置上，同時還具有非常緊湊的介面， 所述介面具有低於3C/W且優選低於2C/W且有潛力低於 1C/W的熱阻。板78安置在凹室83内，凹室83圍繞中心孔 56，以使得板78大體與殼體38的最下外表面齊平。 端子孔60a接近磁體座58a但與磁體座58a間隔開；端子 孔60b也接近磁體座58b但與磁體座58b間隔開。端子孔6〇a 鄰近於基部50的一個邊緣，而端子孔6〇b鄰近於基部5〇的另 一相對邊緣。各端子孔6〇a、60b自内表面52到外表面54延 伸穿過基部50。 各端子62a、62b由導電材料形成且具有第一部分84、 M436129 第二部分86和第三部分88。各端子62a、62b的第一部分84 設置於且接合於基部50的接近相應的端子孔60a、60b的内 表面52。第二部分86自相應的第一部分84延伸且相對於對 應的第一部分84成一角度。第二部分86延伸穿過相應的端 子孔60a、60b。第三部分88自相應的第二部分86延伸且被 設定為與一電力接觸件接合。各第三部分88彎曲並自外表 面54向外延伸。第二部分86和第三部分88可相對第一部分 84撓曲，以使得第三部分88在撓曲距離的範圍内能合適地 與一電力接觸件接合。在一個實施例中，第二部分86和第 三部分88對於所述撓曲範圍具有至少〇.4mm的容許範圍 (tolerance)。端子62a、62b穿過安裝部到達基部50(例如焊錫） 且經由設置在殼體38上表或内部的導電線路89，從而電連 接於耗能模組40，諸如LED陣列的陽極或陰極。在一個實 施例中，蓋體46和基部50可被設定為圍繞在端子62a、62b 的第二部分86和第三部分88外周的口袋形。在這種實施例 中，蓋體46安裝於所述殼體38，所述蓋體46在所述磁體 42a、42b之上方延伸，以遮蔽所述磁體42a、42b。通過殼 體38和蓋體46在它們之間形成密封梁（sealed beam)來阻止 水或灰塵經由孔56進一步進入到所述總成中。在一個實施 例中’這可通過嚴格控制殼體38和蓋體46之間的配合間隙· 來實現。而在另一實施例中，所述密封可通過採用墊圈來 達成。將蓋體46壓靠在基部50上以使得端子62a、62b夾在 蓋體46和殼體38之間的一個優點在於夾持力提供了用於將 端子62a、62b的第一部分84固定定位的進一步支撐，這使 12 M436129 得作用在第一部分84上的任何其它壓力難以對耗能裝置2〇 的基部50和端子62a、62b之間的接合點造成損害。 耗能裝置20被放置在支撐結構22上，以致磁體42a、42b 處於兩電力接觸件26、28之間且接近於軌道24的底壁30。 磁體42a、42b和執道24之間的磁性吸引提供了將耗能裝置 20固定於執道24的力。介面壁66最好足夠薄以使得不干擾 前述磁性力。如果需要，可設置穿過各介面壁66的孔，以 允許磁體部分延伸穿過介面壁66。然而一般而言，介面壁 66可不設置這種孔。熱橋82定位在電力接觸件26、28之間 的底壁30上並可填充在板78和底壁3〇之間的任意空間。這 確保板78和底壁30之間具有較低的熱阻。根據耗能裝置2〇 的尺寸，可在介面壁66和軌道24之間設有氣隙，只要所述 氣隙不負面影響前述磁性力即可。 端子62a與電力接觸件26配合；端子62b與電力接觸件 28配合。端子62a、62b與電力接觸件26、28接合時，其第 二部分86和第三部分88可在它們的容許範圍内相對第一部 分84撓曲。這將確保端子62a、62b與電力接觸件％、28之 間具有良好的電接觸。 在工作期間，電力（p〇wer)流經電力接觸件26、28、經 過端子62a、62b、沿導電線路89到達耗能模組4〇。耗能模 組40產生的熱必須散發出去（否則耗能裝置2〇的壽命將會 被縮減）。耗能模組40產生的熱經由熱橋82傳遞至底壁3〇。 軌道24起到散熱器的作用。翅片允並不是必需的但可以 用來提供額外的散熱面積。當然，轨道24(和可選的翅片36) 13 M436129 可以根據適當的裝飾設計設計為任何形狀。 通過使用者拉動耗能裝置20離開切結構22來克服所 述磁性力，耗能裝置20可輕易地在支撐結構22上來回運 動。耗能裝置20可隨後容易地重新定位在支撐結構二上。 如果熱橋82设置在耗能裝置2〇上，則希望有足夠的力 來確保耗能裝置20和支撐結構22之間的可靠熱連接。磁體 42a、42b提供了這種力，同時避免在安装期間移動（例如轉 動或滑動)耗能裝置2〇(如果熱橋82是順從性的、具有附著性 質或者在這種移動過程中會變形，這樣將會是優點）^在所 示出的實施例中，磁體42a、42b與軌道24之間的吸引提供 的最小 3psi(0.021MP)、優選 5psi(0.034MP)、且更優選 10psi(0.〇69MP)的壓力有益於提供可靠的熱連接。然而有益 的力的大小取決於耗能裝置20的質量、需要散發的熱量、 以及附接於耗能裝置2〇的所述散熱器的效率。 如第7至15圖所示，供電模組120安置在平的底壁30上 和電力接觸件26、28上。供電模組120包括：下介電殼體 138 ;上介電殼體Π9 ;電源140，由下介電殼體138支撐並 延伸穿過上介電殼體139 ;

The support structure 22 can be easily attached to a support surface such as a wall, ceiling, cabinet, or the like. It should be noted, however, that the support surface can be of any desired shape and can even be configured to allow a socket-like shape or a configuration of a single energy consuming device to be mounted thereon, if desired, The support surface can be recessed within the housing (it should be understood that the heat dissipation benefits provided by the rails 24 may need to be provided by other structures). As shown, the track 24 is comprised of a bottom wall 3〇 (which is shown as being flat) and side walls 32, 34 extending perpendicularly from opposite edges of the bottom wall 30. A plurality of fins 36 M436129 extend outwardly from the sidewalls 32,34. The track 24 is thermally conductive and may also be electrically conductive, and if electrically conductive, the pair of elongated electrical contacts 26, 28 are electrically insulated from the obstruction 24 via a suitable insulator 37, such as A non-conductive double-sided tape, paint or anodic oxide disposed on the track 24. The track 24 can be formed from an extruded plastic that has a clock (e.g., plated with nickel and tin), the track 24 can be formed entirely of metal, or can be a hybrid combination of a plastic piece and a metal piece. While the side walls 32, 34 are shown as being straighter than the bottom wall 30, it should be understood that in certain embodiments, the side walls & 34 may be eliminated or may be at other angles relative to the bottom wall 30. The energy consuming device 20 is disposed on the bottom wall 30 and the electrical contacts 26, 28. The track 24 can act as a heat sink for the energy consuming device 2A as described herein. The energy consuming device 20 includes: a housing % formed of a dielectric material; an energy consuming module 40 supported by the body 38; - a magnet 42a, 42b supported by the housing 38; and a pair supported by the housing 38. Terminals 62a, 62b. For illumination, the energy consuming module 40 can include an array of LEDs (the LED array can be one or more LEDs arranged in a desired pattern), but can be other energy consuming devices, such as not limited to radios, cameras, senses. The detector, and the energy consuming device 20 can also project an image or emit a sound by including a device such as a speaker 'image projector as needed. A decorative cover 46 can be positioned over the housing 38 and cover the energy consuming module 40 and the magnets 42a, 42b. A lens or other light styling element 48 can be provided as is known in the art and can be supported by the housing 38 and/or the cover 46 to direct light from the energy consuming module 40 (if set to an LED array). Guided. The housing 38 can take a variety of shapes, such as a circular shape as shown in Fig. 1, a rectangle, a square, a triangle, an ellipse, and the like as shown in Fig. 2 of Fig. The housing % includes a base 50 having an inner surface 52 and an outer surface 54; a hole 56 extending through the base 50; and magnet holders 58a, 58b disposed at each end of the base 50 and separated by a central aperture 56; One and second terminal holes 60a, 60b and their associated terminals 62a, 62b. It should be noted that although shown as a dual magnet holder, the housing 38 may be otherwise configured to provide a single magnet holder. For example, but not limited to, one end of the housing 38 can be retained via the lip provided by the support structure 22 and then a single magnet holder and associated magnet will be sufficient to securely position the housing 38. Alternatively, a magnet holder can be located at a central location on the housing 38 such that the force is evenly distributed across the ends (and the thermal bridge, if included). A portion of the energy consuming module 40 extends through the base 50 via the aperture 56. The magnet 42a is disposed in the magnet holder 58a; the magnet 42b is disposed in the magnet holder 58b. The magnets 42a, 42b are shown as being rectangular in cross section to facilitate the manufacture of the element, however, other various shapes of magnets 42a, 42b may be employed. Each of the magnet holders 58a, 58b is formed as a recess extending from the inner surface 52. Each of the magnet holders 58a, 58b has a plurality of side walls 64 extending from the inner surface 52 and an interface wall 66. Each of the magnet holders 58a, 58b preferably conforms to the shape of the magnets 42a, 42b' and the magnets 42a, 42b may extend from the inner surface 52 of the housing 38 or be flush with the inner surface 52 of the housing 38 as shown. The cover 46 can take a variety of shapes to accommodate the energy consuming module 40 and an optional optic 48. For example, without limitation, the cover 46 can be completely flat, the cover 46 can also be substantially flat and have a raised central portion to receive the optical device 48' and the cover 46 can also be concave or convex. The illustrated cover 46 includes a cover wall 68 having an inner surface 70 and an outer surface 72; a hole through which the 9 M436129 passes through the center of the cover wall 68 into which the lens or other light shaping element 48 is mounted. The magnet holders 74a, 74b are disposed at respective ends of the cover wall 68 and are separated by the center hole; and the side walls 75a, 75b, 75c, 75d extend from the edge of the cover wall 68. When the cover 46 is placed on the housing 38, the magnet 42a is held in the magnet holder 74a. The magnet 42b is held in the magnet holder 74b, and the side walls 75a, 75b, 75c, 75d are engaged with the edges of the housing 38. Each of the magnet holders 74a, 74b has a side wall 76 extending from the inner surface 70 while the inner surface 70 forms the bottom wall of the recess. A portion of the side walls 75b, 75d form a portion of the respective magnet holders 74a, 74b. However, it will be appreciated that although the side walls 75b, 75d of the cover 46 are shown as part of the magnet holders 74a, 74b, separate walls may be provided on the cover 46 to form the remainder of the magnet holders 74a, 74b. section. Each of the magnet holders 74a, 74b preferably has the same shape as the magnets 42a, 42b. Thus, it can be appreciated that the magnets 42a, 42b are sandwiched between the inner surface 70 and the interface wall 66 and are thus retained in position. Additional constraints are provided by the side walls 76, 75b, 75d k. However, any desirable constraints are suitable. For example, the magnets 42a, 42b are attached using an adhesive or other fastening system. The benefit of retaining the magnets 42a, 42b between the housing 38 and the cover 46 is that manufacturing costs can be reduced. As shown, the energy consuming module 40 is configured as a solid state lighting element that includes a plate 78 that is disposed on the board 78 and protected by a cover 46. The plate 78 can be a thermally conductive material, such as aluminum covered with an insulating layer on which the array of LEDs is placed. Alternatively, if the energy consuming module 40 is less sensitive to thermal decay, the board 78 can be a circuit board or some other composite structure. A thermal bridge 82 (which may be, but is not limited to, a thermal pad or thermal paste) 10 may be disposed on the outer surface of the energy consuming module 40 (eg, on the lower surface of the plate 78). Thermal bridge 82 can be a thermally conductive adhesive gasket such as, for example, 3M thermal tape 8810. As shown, the thermal bridge 82 connects the plate 78 to the bottom wall 3〇. In the illustrated embodiment, the plate 78 is configured to have a lower thermal resistance between the plate 78 and the LED array (preferably the plate will have greater than 5 watts/meter - Kelvin ((W) / (m K)) thermal conductivity 'and more preferably will have a large K1 〇〇 w / (m K) thermal conductivity), and the thermal bridge 82 effectively connects the plate 78 to the bottom wall 30, the LED array and The total thermal resistance between the bottom walls 30 will be less than 3 c /w and preferably less than 2 C/W. In addition, if the thermal bridge 82 is kept thin and a material having a relatively high thermal conductivity is selected, then the total The thermal resistance is less than 1 C/W. For example, if a BRIDGELUX LED array is used in combination with a suitable thermal bridge and sufficient force is applied by the magnets 42a, 42b, this design is feasible. As a result, the illustrated design generally allows a magnetic snubber device 2 with a very efficient heat transfer arrangement, allowing for use on illuminators with brightness greater than 500 lumens, while also having a very compact interface. The interface has a thermal resistance of less than 3 C/W and preferably less than 2 C/W and a potential of less than 1 C/W. The plate 78 is placed in the recess 83 The recess 83 surrounds the central aperture 56 such that the plate 78 is generally flush with the lowermost outer surface of the housing 38. The terminal aperture 60a is adjacent to the magnet holder 58a but spaced apart from the magnet holder 58a; the terminal aperture 60b is also proximate to the magnet holder 58b but It is spaced apart from the magnet holder 58b. The terminal hole 6〇a is adjacent to one edge of the base 50, and the terminal hole 6〇b is adjacent to the other opposite edge of the base 5〇. Each of the terminal holes 6〇a, 60b is from the inner surface 52 to The outer surface 54 extends through the base 50. Each terminal 62a, 62b is formed of a conductive material and has a first portion 84, a M436129 second portion 86 and a third portion 88. The first portion 84 of each terminal 62a, 62b is disposed and bonded to the base portion The inner surface 52 of the corresponding terminal holes 60a, 60b is adjacent to the second terminal portion 60. The second portion 86 extends from the corresponding first portion 84 and is at an angle relative to the corresponding first portion 84. The second portion 86 extends through the corresponding terminal hole 60a, 60b. The third portion 88 extends from the respective second portion 86 and is configured to engage a power contact. Each third portion 88 is curved and extends outwardly from the outer surface 54. The second portion 86 and the third portion 88 can Flexing relative to the first portion 84 to The third portion 88 is suitably engageable with a power contact within a range of flexural distance. In one embodiment, the second portion 86 and the third portion 88 have an allowance of at least 〇4 mm for the deflection range. The terminals 62a, 62b pass through the mounting portion to the base 50 (e.g., solder) and are electrically connected to the energy consuming module 40, such as an LED array, via conductive traces 89 disposed on the surface or interior of the housing 38. The anode or cathode. In one embodiment, the cover 46 and the base 50 can be configured to surround the outer circumference of the second portion 86 and the third portion 88 of the terminals 62a, 62b. In such an embodiment, a cover 46 is mounted to the housing 38 and the cover 46 extends over the magnets 42a, 42b to shield the magnets 42a, 42b. A sealed beam is formed between the shell 38 and the cover 46 to prevent water or dust from entering the assembly further through the aperture 56. In one embodiment, this can be achieved by tightly controlling the fit clearance between the housing 38 and the cover 46. In yet another embodiment, the sealing can be achieved by the use of a gasket. One advantage of pressing the cover 46 against the base 50 such that the terminals 62a, 62b are sandwiched between the cover 46 and the housing 38 is that the clamping force provides for secure positioning of the first portion 84 of the terminals 62a, 62b. Further support, this makes it difficult for 12 M436129 to act on the first portion 84 to cause damage to the joint between the base 50 of the energy consuming device 2 and the terminals 62a, 62b. The energy consuming device 20 is placed on the support structure 22 such that the magnets 42a, 42b are between the two electrical contacts 26, 28 and proximate to the bottom wall 30 of the track 24. The magnetic attraction between the magnets 42a, 42b and the obstruction 24 provides the force to secure the energy consuming device 20 to the lane 24. The interface wall 66 is preferably thin enough so as not to interfere with the aforementioned magnetic forces. If desired, holes can be provided through each of the interface walls 66 to allow the magnet portions to extend through the interface wall 66. In general, however, the interface wall 66 may not be provided with such holes. The thermal bridge 82 is positioned on the bottom wall 30 between the electrical contacts 26, 28 and can fill any space between the plate 78 and the bottom wall 3A. This ensures a lower thermal resistance between the plate 78 and the bottom wall 30. Depending on the size of the energy consuming device 2A, an air gap may be provided between the interface wall 66 and the rail 24 as long as the air gap does not adversely affect the aforementioned magnetic force. Terminal 62a is mated with power contact 26; terminal 62b is mated with power contact 28. When the terminals 62a, 62b are engaged with the power contacts 26, 28, the second portion 86 and the third portion 88 can flex relative to the first portion 84 within their tolerances. This will ensure good electrical contact between the terminals 62a, 62b and the power contacts %, 28. During operation, power flows through the power contacts 26, 28, through the terminals 62a, 62b, and along the conductive line 89 to the energy consuming module 4A. The heat generated by the energy-consuming module 40 must be dissipated (otherwise the life of the energy-consuming device 2〇 will be reduced). The heat generated by the energy consuming module 40 is transferred to the bottom wall 3 via the thermal bridge 82. The track 24 functions as a heat sink. Finning is not required but can be used to provide additional heat dissipation area. Of course, track 24 (and optional fins 36) 13 M436129 can be designed in any shape according to the appropriate decorative design. The energy consuming device 20 can be easily moved back and forth over the support structure 22 by the user pulling the energy consuming device 20 away from the cutting structure 22 to overcome the magnetic force. The energy consuming device 20 can then be easily repositioned on the support structure 2. If the thermal bridge 82 is disposed on the energy consuming device 2, it is desirable to have sufficient force to ensure a reliable thermal connection between the energy consuming device 20 and the support structure 22. The magnets 42a, 42b provide such force while avoiding moving (e.g., rotating or sliding) the energy consuming device 2(b) during installation (if the thermal bridge 82 is compliant, has adhesive properties, or deforms during such movement, This would be an advantage. In the illustrated embodiment, the attraction between the magnets 42a, 42b and the track 24 provides a minimum of 3 psi (0.021 MP), preferably 5 psi (0.034 MP), and more preferably 10 psi (0. The pressure of 〇69MP) is beneficial to provide a reliable thermal connection. However, the amount of beneficial force depends on the mass of the energy consuming device 20, the amount of heat that needs to be dissipated, and the efficiency of the heat sink attached to the energy consuming device. As shown in Figures 7 through 15, the power supply module 120 is disposed on the flat bottom wall 30 and the electrical contacts 26, 28. The power supply module 120 includes a lower dielectric housing 138, an upper dielectric housing Π9, and a power supply 140 supported by the lower dielectric housing 138 and extending through the upper dielectric housing 139; supporting the magnets 142a, 142b Between the lower dielectric housing 138 and the upper dielectric housing 139; and a pair of terminals 162a, 162b supported by the lower dielectric housing 138. A dielectric cover 146 is positioned over the lower housing 138 and the upper dielectric housing 139 and covers the power source 140, the magnets 142a, 142b, and the pair of terminals 162a' 162b. The upper dielectric housing 138 includes a generally flat bottom wall 150 having an inner surface 152 and an outer surface 154, magnet holders 15 8a, 158b disposed on opposite sides of the two 14 M436129 of the bottom wall 150, and first and second terminals Holes 16A, 160b and their associated terminals 162a, 162b. Power source 140 is disposed within recess 156 in bottom wall 150. The magnet 142a is disposed in the magnet holder 158a, and the magnet 142b is disposed in the magnet holder 158b. As shown, the magnets 142a, 142b are preferably rectangular in cross-section for ease of manufacture, however, other shapes for the magnets 142a, 142b are also contemplated, and unless otherwise stated, The shape is limited. Each of the magnet holders 158a, 158b is formed as a recess extending from the inner surface 152. Each of the magnet holders 158a, 158b has a plurality of side walls 164 extending from the inner surface 152 and a flat bottom wall 166. Each of the magnet seats 158a, 158b preferably conforms to the shape of the magnets 142a, 142b, and the magnets 142a, 142b may extend from the inner surface 152 of the lower dielectric housing 138 or may be associated with the lower dielectric housing 138 as shown. The inner surface 152 is flush. The terminal hole 160a is close to the magnet holder 158a but spaced apart from the magnet holder 158a; the terminal hole 160b is close to the magnet holder 158b but spaced apart from the magnet holder 158b. The terminal hole 160a is adjacent to one side edge of the bottom wall 150, and the terminal hole 160b is adjacent to the opposite other side edge of the bottom wall 150. Each of the terminal holes 16A, 160b extends from the inner surface 丨52 to the outer surface 154 through the bottom wall 15A. As can be appreciated from Figure 14, each of the terminals 1623, 162b is formed of a conductive material and has: a flat base 184; a first portion 186, a second portion 188, a third portion 19A extending from the base 184; And a pair of collecting portions 192 and 194. The bases 184 of the respective terminals i62a, 162b are disposed in the recesses 196a, 196b in the inner surface 152 of the bottom wall 150 that are adjacent to the respective terminal holes 16a'' 16b. The first portion 186 extends perpendicularly from the base 184. The second portion 188 extends from the respective first portion 186 and is at an angle relative to the respective first portion 15 M436129. The third portion 190 extends from the respective second portion 188 and is generally perpendicular to the corresponding first portion 186. Each of the third portions 190 is curved and extends through the respective terminal holes 160a, 160b. The third portion 190 extends outwardly from the outer surface 154. The second portion 188 and the third portion 190 can flex relative to the first portion 186. Preferably, the second portion 188 and the third portion 190 have a deflection tolerance of at least 〇, 4 mm, which will be discussed in greater detail below. The hub portions 192, 194 are connected to wires or blade switches (not shown). The terminals 162a, 162b are electrically connected to the power source 140 via conductive lines disposed on the inside or the inside of the lower dielectric case 138. Alternatively, terminals 162a, 162b may be coupled to power source 140 via insulated conductors (e.g., insulated wires). The upper dielectric housing 139 is disposed over the lower dielectric housing 138 and covers the magnets 142a, 142b and the terminals 162a, 162b. The upper dielectric housing 139 can include a hole 199 through itself to allow the power source 140 to pass therethrough. When the upper dielectric housing 139 is placed over the lower dielectric housing 138, the magnets 142a, 142b are sandwiched between the lower dielectric housing 138 and the upper dielectric housing 139. The cover 146 covers the lower dielectric housing 138 and the upper dielectric housing 139 and is properly attached to them. The power supply module 120 is mounted on the support structure 22, and the magnets 142a, 142b are disposed on the power contacts 26 of the track 24, Above the 28th. The magnetic attraction between the magnets 142a, 142b and the track 24 provides the force to secure the power module 12 to the track 24. The bottom wall 166 is sufficiently thin to not interfere with the magnetic force. Terminal 162a mates with power contact 26; terminal 162b mates with power contact 28. When the terminals 162a, 162b are engaged with the power contacts 26, 28, the second portion 188 and the third portion 190 flex relative to the first portion 186 within their tolerances. This ensures good electrical contact between the terminals 162a, 162b and the power contacts 26, 28 of 16 M436129. It will be appreciated that during the I operation, current flows from the power source 140 along the wires or conductive lines that are connected to the contacts i6a, 16 through the contacts 162a, 162b to the power contacts %, 28, and subsequently reach The device 20 can be installed. As described above, the terminals can be flexed within a predetermined range and as described, provide a reliable electrical contact at about the same time. Although it is more likely to ride # for a smaller allowable range of m, it has been confirmed that an allowable range of more than 0.5 mm and preferably greater than 〇.8 mm is advantageous for ensuring the support surface provided by the branch structure 22 (such as the bottom wall 3G). Good thermal contact is formed between them. This is because A, when using T-compression heat bridge Japanese temple, is beneficial to ensure that the terminal is engaged with the power contact, but once it has a good electrical connection, the focus of consideration is changed to ensure that the thermal bridge can provide better Hot interface. This may involve having the thermal bridge have some compression range. By allowing the terminals to flex within the disclosed range while still providing good electrical contact, then controlling various tolerances while still ensuring low thermal resistance (which is beneficial for a longer life of the energy consuming device) will become It's simpler. This allows the thermal bridge to provide higher thermal conductivity while providing less compressibility. Overcoming the magnetic force by the user pulling the power supply module 120 away from the support structure 22 The power supply module 120 can easily move back and forth over the support structure 22. The power supply module 120 can then be easily repositioned on the support structure 22. Alternatively, the lower dielectric housing 138 and the cover 146 can include ears 200, 202 through which the fasteners (not shown) can securely attach the power module no to the track 24. If the outer module 2, 202 is used to fix the power module 120 to the branch structure 22, the magnets 142a, 142b can be omitted. 17 M436129 Although the magnets 142a, 142b are shown disposed above the power contacts 26, 28 'but it will be appreciated that the magnets 142a, 142b may be disposed on the lower dielectric housing 138 such that the magnets 142a, 142b are disposed in the electrical contacts Above the track 24 between 26 and 28. However, for rails 24 that are not ferrite based materials and power contacts 26, 28 are ferrite based materials, it may be beneficial to position magnets 142a, 142b above power contacts 26, 28. Jumper device 320 is shown in Figures 14 and 16-18. Jumper device 320 provides a means for attaching one support structure 22 to another support structure (not shown). Jumper device 320 is disposed above bottom wall 30 and power contacts 26, 28. The jumper device 320 includes: a dielectric housing 338; a pair of magnets 342a, 342b supported in the dielectric housing 338, a pair of terminals 362a, 362b and a dielectric cover 346 to which the dielectric cover 346 is attached The dielectric housing 338 covers the magnets 342a, 342b and the terminals 362a, 362b. The dielectric housing 338 includes: a bottom wall 350 that is planar in shape, having an inner surface 352 and an outer surface 354, two magnet seats 358a, 358b disposed on opposite sides of the bottom wall 350; and first and first Two terminal holes 360a, 360b and their associated terminals 362a, 362b. As shown, the magnet 342a is disposed in the magnet holder 358a and the magnet 342b is disposed in the magnet holder 358b. As shown, the magnets 342a, 342b may be rectangular in cross section for ease of manufacture; however, other shapes for the magnets 342a, 342b are also suitable. Each of the magnet seats 358a, 358b is formed as a recess extending from the inner surface 352. Each of the magnet seats 358a, 358b has a plurality of side walls 364' extending from the inner surface 352; and a flat bottom wall 366. The outer shape of each of the magnet seats 358a, 358b preferably conforms to the shape of the 18 M436129 of the magnets 342a, 342b, and the magnets 342a, 342b may extend from the inner surface 352 of the dielectric housing 338 or may be 352 with the inner surface 352 of the dielectric housing 338. Qi Ping. The terminal hole 360a is close to the magnet holder 358a but spaced apart from the magnet holder 358a; the terminal hole 360b is close to the magnet holder 358b but spaced apart from the magnet holder 35. The terminal hole 360a is adjacent to one side edge of the bottom wall 350, and the terminal hole 360b is adjacent to the opposite side edge of the bottom wall 350. Each of the terminal holes 36A, 36B extends from the inner surface 352 to the outer surface 354 through the bottom wall 35A. The terminals 362a, 362b may be identical in construction to the terminals shown in Fig. 14 and thus will not be repeated here. The bases 384 of the respective terminals 362a, 362b are disposed in the recesses 396a, 396b in the inner surface 352 of the bottom wall 350 that are adjacent to the respective terminal holes 36a, 360b. Each of the third portions 390 extends through respective terminal holes 360a, 360b and extends outwardly from the outer surface 354. The hub portions 392, 394 are connected to a wire or knife switch (not shown) connected to the power supply module 12A or a wire/knife type switch extending from the adjacent energy consuming device 20. A dielectric cover 346 is disposed over the dielectric housing 338 and conformably attached to the dielectric housing 338. A dielectric cover 346 is placed over the magnets 342a, 342b and the terminals 362a, 362b. When the dielectric cover 346 is placed over the dielectric housing 338, the magnets 342a, 342b are sandwiched between the dielectric cover 346 and the dielectric housing 338. Jumper device 320 is placed over support structure 22, and magnets 342a, 342b are placed over power contacts 26, 28 of way 24. The magnetic attraction between the magnets 342a, 342b and the track 24 provides the force to secure the jumper device 320 to the track 24. The bottom wall 366 is sufficiently thin to not interfere with the magnetic force. Terminal 362a mates with power contact 26; terminal 362b mates with power contact 28. When terminals 362a, 362b are engaged with power contacts 26, 28, terminals 362a, 362b can flex within the tolerance of their 19 M436129. This will ensure good electrical contact between the terminals 362a, 362b and the power contacts 26, 28. In fact, two jumper sets 32 〇 can be used to power two adjacent tracks 24. During operation, current flows from the power source 14 to the terminals 162a, 162b, the power contacts 26, 28 along the first track 24, through the terminals 362a, 362b of the first jumper device 320, and along the turns 192/392 a wire or knife switch between 194/394, passing through terminals 362a, 362b of the second jumper device 320 to the power contacts 26, 28 of the second track 24 (and subsequently reaching the second track 24) Any energy consuming device). Overcoming the magnetic force by the user pulling the jumper device 320 away from the support structure 22' the jumper device 320 can be easily attached to or detached from the wrap structure 22. Although the magnets 342a, 342b are shown positioned above the power contacts 26, 28, it will be understood that the magnets 342a, 342b may be disposed on the dielectric housing 338, the magnets 342a, 342b being positioned on the bottom wall of the track 24. Above 30 (eg 'between power contacts 26, 28'). It will be appreciated that the 'energy consuming device 2', the power supply module 120, the jumper device 320, and the whip structure 22 are all configured to provide a profjie system. This is beneficial in many situations, such as when the space is shallow. To this end, the flat bottom wall 30 and the fins 36 are extended from the bottom wall 30 at least twice the distance from the bottom wall 30 of the electrical contacts 26, 28, together with a relatively small compact energy consuming device 20 - The presently disclosed embodiment presents a simple and elegant decorative appearance that is confirmed to be desirable and feasible. If the fins 36 extend over the bottom wall 3〇 by more than twice the power contacts 26, 28, the appearance would be more desirable 'and if the fins 36 extend up to four times greater than the power contacts 26, 28' More preferably. Additionally, the top of the energy consuming device 20 can extend to at least five times the height of the electrical 20 M436129 force contacts 26, 28 while engaging the bottom wall 30 between the electrical contacts 26, 28 with the thermal bridge 82. For example, if the power contacts %, 28 extend over the bottom wall 30 by about 66 mm, the top of the energy consuming device 20 can be between 6.Omm and 10 mm above the bottom wall 30 (eg, greater than $ times Still less than 20 times the height to provide a beneficial aesthetic appearance). For example, referring to Figures 19 and 20, the system is disclosed as including an energy consuming device 20' mounted to a track 24·. It will be appreciated that upon installation, the energy consuming device 20' extends a height D1 above the bottom wall 30' and the track 24' has fins 34' extending a distance D2 above the bottom wall 3 (in some In an embodiment, D2 will be greater than 1/2 D1 'and D2 is greater than D1 as shown. It will be appreciated that the interface wall 66' of the housing 38' is positioned on the electrical contact 28' and the plate 78' will be hot The bridge 82 is pressed between the plate 78 and the bottom wall 30'. Further, the distance that the 'power contact 28' extends upward from the bottom wall 30' should be kept short so that for an attractive and elegant appearance, the distance D2 It should be at least three times the distance D3, preferably D2 should be more than 10 times that of D3. When the assembly is applied to a visible situation, the shape of the design will be important, especially in a commercial environment. The appearance of the final embodiment will affect the behavior of those who see the design. Figure 21 illustrates an embodiment of a support structure 222 that is functionally similar to the support structure 22 shown in Figure 1. It is appreciated that the support structure 222 is configured to securely support the energy consuming device 220, and the energy consuming device 220 can be as above Specifically, the channel 241 is configured to allow the energy consuming device 220 to be viewed because the channel 241 is in communication with the exterior of the support structure 222. As shown, a first lip 233, The first side wall 235 extends outwardly toward the second side wall 235 of the pair of phase 21 M436129; and a second lip 233 extends outwardly from the second side wall 235 toward the opposite first side wall 235. The lip 233 and the second lip 233 are opposite to each other. A first power contact 228 and a second power contact 228 are disposed between the first sidewall 235 and the second sidewall 235; the channel 241 is supported by The side wall 235 of the lip 233 is formed and the lip 233 is integral with the support structure 222. However, as can be appreciated from Figures 24, 30 and 31, a separable interface is also contemplated. For example, a top support structure 222b There will be two heads 290 and a plurality of legs extending between the heads 290, while each leg has an outer edge 296 and an inner edge 295, and the two inner edges 295 form a channel 241. The distance between the heads 290 is sufficiently large that an optional coupler 297 Applying to one or both legs to secure the top support structure 222b to the bottom support structure and to ensure that the legs are held in the desired position. Additionally, it should be noted that the top support structure 222b will be the legs It is arranged to be more u-shaped, such as shown in FIG. 3 'the simultaneous top support structure 322b is mounted to the bottom support structure 322a to form the channel 34. Alternatively, one top support structure 42 is flat and mounted on one The bottom support structure 422a is formed to form the channel 441. The benefit of the one-piece design is that the support structure can be provided in a simple manner. The benefit of the two-piece design is that different components will be formed in one stamping process. Whether the support structure is a one-piece type with a head or a two-piece design (for example, a top support structure and a bottom support structure, the head is disposed therein), and a more desirable one is needed. The locking mechanism secures the various components (instead of or in addition to conventional fasteners). For example, a lock 292 or a comparator 293 can be provided. The lock 22 M436129 can be a conventional key-based lock or require special tools to separate the head 290 from the support structure 222. In addition, it should be noted that the manner in which the head 29〇 supports the terminal can also be similar to the manner in which the contact member is supported in the embodiment shown in Fig. 18 (for example, when the head 290 is mounted, the head 29 will be The terminal block is engaged with the power contact 228 and the terminal will have a hub that allows the terminal to be connected to the power source. Of course, header 290 may contain additional functionality as desired, it being understood that adding functionality will cause head 290 to become larger. In practice, the support structure 222 (which can be shaped in the desired manner in accordance with the desired function and features) is provided with slots 225 (typically two opposing slots but only one if the slot 225 is deep enough) 'slot 225 With respect to the wall opening, and due to the fact that the housing of the energy consuming device 220 cannot be fully rotated or tilted out of the slot 225, the slot 225 allows the energy consuming device 220 to follow the support structure 222 without disabling the energy consuming device 220. The bottom wall 223 of the bottom wall 223 also supports the power contact 228 moves. As can be appreciated from Figures 26 and 27, for example, the energy consuming device 220 has a housing 22a with a surface A' that engages the surface B to prevent the energy consuming device 220 from the support structure 222. Get out of the way. In order to help ensure that the energy consuming device 220 is not operated and subsequently detached, the surface C of the energy consuming device 220 can be placed sufficiently close to the surface D of the support structure 222 to ensure that the surface B prevents the accommodating device 220 from escaping. The distance between surface A and surface B can be adjusted 'to allow energy consuming device 220 to translate along the support structure. Figures 28 and 29 illustrate a system with two slots, and if the energy consuming device attempts to detach from the power contact 228, the surface A will engage the surfaces B and B', while the surfaces c and C' will It is possible to join surfaces D and D', respectively. Thus, as can be appreciated from Figure 29, the distance 301 is the average distance between the energy consuming module 23 and the support structure, and the distance 301 will be set such that the corner 298 cannot pass through the edge 299 during operation. Of course, if the distance 3〇1 is kept small, the distance that the edge 299 extends over the corner 298 can also be reduced. However, to ensure ease of operation when positioning the energy consuming device, it would be appropriate to set the distance 3〇1 to at least 1 mm. The exemplary embodiments are shown and described herein, but it is contemplated that various modifications may be made by those skilled in the art without departing from the scope of the invention.
