Description
本發明是有關於一種膠套，且特別是有關於一種電容器元件之膠套。The present invention relates to a rubber sleeve, and more particularly to a rubber sleeve for a capacitor element.
電容器是一種在兩金屬板之間存在絕緣介質的儲能元件，在電路中用於調諧、濾波、耦合、旁路、能量轉換和延時。目前，已被普遍應用於各種電子裝置。A capacitor is an energy storage element that has an insulating medium between two metal plates for tuning, filtering, coupling, bypassing, energy conversion, and delay in the circuit. At present, it has been widely applied to various electronic devices.
依據電容器特性原理的不同，可分為化學電容器與非化學電容器二大類。化學電容器是指採用電解質作為電容器陰極的一類電容器，如電解電容器。非化學電容器則是例如陶瓷電容器、紙介電容器、塑膠薄膜電容器、半導體電容器等。According to the principle of capacitor characteristics, it can be divided into two major categories: chemical capacitors and non-chemical capacitors. A chemical capacitor refers to a type of capacitor that uses an electrolyte as a cathode of a capacitor, such as an electrolytic capacitor. Non-chemical capacitors are, for example, ceramic capacitors, paper capacitors, plastic film capacitors, semiconductor capacitors, and the like.
現今電解電容器以鋁質電解電容器最為常見。鋁質電解電容器是以鋁當陽極，並以乙二醇、丙三醇、硼酸及氨水等所組成的糊狀物當作電解液。電解液發生化學反應，使鋁表面產生一種極薄的氧化鋁膜為介質。電解電容器外部以膠套包覆以絕緣。Today, electrolytic capacitors are most commonly used in aluminum electrolytic capacitors. The aluminum electrolytic capacitor is made of aluminum as an anode, and a paste composed of ethylene glycol, glycerin, boric acid, ammonia water or the like is used as an electrolyte. The electrolyte reacts chemically to produce an extremely thin aluminum oxide film on the aluminum surface. The outside of the electrolytic capacitor is covered with a rubber sleeve to insulate.
圖1是習知之一種電容器之示意圖。習知之電容器100之膠套120以熱縮方式包覆於電容器元件110。由於電容器元件110與膠套120之間存在氣體，熱縮過程中氣體被膠套120包覆而無法逸散，因此膠套120可能發生無法完全貼合電容器元件110之狀況。此時，膠套120之一部份會受氣體擠壓而膨脹形成一變形處130。1 is a schematic view of a conventional capacitor. The rubber sleeve 120 of the conventional capacitor 100 is coated on the capacitor element 110 in a heat shrinkable manner. Due to the presence of gas between the capacitor element 110 and the rubber sleeve 120, the gas is covered by the rubber sleeve 120 during heat shrinkage and cannot escape. Therefore, the rubber sleeve 120 may not fully conform to the capacitor element 110. At this time, a portion of the rubber sleeve 120 is squeezed by the gas to expand to form a deformation 130.
本發明提供一種膠套，可服貼地包覆於電容器元件外。The invention provides a rubber sleeve which can be wrapped around a capacitor element in a conformable manner.
本發明提供一種電容器，其膠套可緊密貼合於電容器元件。The present invention provides a capacitor whose rubber sleeve can be closely attached to a capacitor element.
本發明提出一種膠套用於包覆一電容器元件。膠套包括一本體，本體具有多個孔洞。當膠套包覆電容器元件時，電容器元件與膠套之間的氣體適於自孔洞排出。The invention proposes a rubber sleeve for coating a capacitor element. The rubber sleeve includes a body having a plurality of holes. When the rubber sleeve covers the capacitor element, the gas between the capacitor element and the rubber sleeve is adapted to be discharged from the hole.
本發明更提出一種電容器包括一電容器元件以及一膠套。膠套包覆於電容器元件，膠套包含一本體，且本體具有多個孔洞。電容器元件與膠套之間的氣體適於自孔洞排出。The invention further provides a capacitor comprising a capacitor component and a rubber sleeve. The rubber sleeve is coated on the capacitor component, the rubber sleeve comprises a body, and the body has a plurality of holes. The gas between the capacitor element and the rubber sleeve is adapted to be discharged from the hole.
基於上述，本發明之電容器及膠套直接在本體上設置孔洞，不但仍可維持原有包覆電容器元件的功能，更可在膠套熱縮包覆電容器元件時，使電容器元件與膠套之間的氣體自孔洞排出，以避免膠套變形而影響電容器外觀。Based on the above, the capacitor and the rubber sleeve of the present invention directly provide holes in the body, not only can maintain the function of the original coated capacitor component, but also enable the capacitor component and the rubber sleeve when the rubber sleeve is heat-shrinked and coated with the capacitor component. The gas is discharged from the hole to avoid deformation of the rubber sleeve and affect the appearance of the capacitor.
為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
本發明提出一種膠套，用於包覆一電容器元件。圖2是依照本發明之第一實施例之一種膠套的俯視示意圖。請參閱圖2，本實施例之膠套200包括一本體210。本體210具有多個孔洞220，且孔洞220以陣列之方式排列。在本實施例中，本體210之材料為熱縮材料，當受熱時膠套200緊縮而貼合於電容器元件。The invention proposes a rubber sleeve for coating a capacitor element. 2 is a top plan view of a rubber sleeve in accordance with a first embodiment of the present invention. Referring to FIG. 2, the rubber sleeve 200 of the embodiment includes a body 210. The body 210 has a plurality of holes 220, and the holes 220 are arranged in an array. In the present embodiment, the material of the body 210 is a heat shrinkable material, and when heated, the rubber sleeve 200 is tightened to fit the capacitor element.
本發明之膠套200利用本體210上具有孔洞220之設計，使得膠套200熱縮包覆電容器元件時，電容器元件與膠套200之間的氣體可自孔洞220排出。如此，膠套200便可緊密貼合於電容器元件。在本實施例中，電容器元件之種類為電解電容器，但不以此為限。The rubber sleeve 200 of the present invention utilizes a design of the hole 220 in the body 210 such that when the rubber sleeve 200 is heat-shrinked to cover the capacitor element, gas between the capacitor element and the rubber sleeve 200 can be discharged from the hole 220. In this way, the rubber sleeve 200 can be closely attached to the capacitor element. In this embodiment, the type of the capacitor element is an electrolytic capacitor, but is not limited thereto.
圖3是依照本發明之第二實施例之一種膠套的俯視示意圖。請參閱圖3，在本實施例之膠套300中，本體310之孔洞320是以不規則的狀態排列。由圖2與圖3可知，此兩實施例的差異僅在於孔洞220、320之分布方式。3 is a top plan view of a rubber sleeve in accordance with a second embodiment of the present invention. Referring to FIG. 3, in the rubber sleeve 300 of the embodiment, the holes 320 of the body 310 are arranged in an irregular state. As can be seen from FIG. 2 and FIG. 3, the difference between the two embodiments lies only in the manner in which the holes 220 and 320 are distributed.
此外，雖圖2與圖3中所繪製之孔洞220、320之尺寸大小一致，但製造者可視情況改變孔洞220、320之尺寸大小，使得本體210、310具有大小不一的孔洞220、320。只要膠套200、300可包覆電容器元件，並且當膠套200、300熱縮包覆電容器元件時，電容器元件與膠套200、300之間的氣體可自孔洞220、320排出即可。In addition, although the sizes of the holes 220 and 320 drawn in FIG. 2 and FIG. 3 are the same, the size of the holes 220 and 320 may be changed by the manufacturer as the case may be, so that the bodies 210 and 310 have holes 220 and 320 of different sizes. As long as the rubber sleeves 200, 300 can cover the capacitor elements, and when the rubber sleeves 200, 300 heat shrink the capacitor elements, the gas between the capacitor elements and the rubber sleeves 200, 300 can be discharged from the holes 220, 320.
本發明更提出一種電容器，其膠套可緊密貼合於電容器元件。圖4是依照本發明之第一實施例之一種電容器的立體示意圖。請參閱圖4，本實施例之電容器400包括一電容器元件410以及一膠套420。在本實施例中，電容器元件410之種類為電解電容器，但不以此為限。The invention further proposes a capacitor whose glue sleeve can be closely attached to the capacitor element. 4 is a perspective view of a capacitor in accordance with a first embodiment of the present invention. Referring to FIG. 4, the capacitor 400 of the embodiment includes a capacitor element 410 and a rubber sleeve 420. In the present embodiment, the type of the capacitor element 410 is an electrolytic capacitor, but is not limited thereto.
膠套420包含一本體422，且本體422具有多個孔洞424。當膠套420熱縮包覆於電容器元件410時，電容器元件410與膠套420之間的氣體可自孔洞424排出。在本實施例中，孔洞424以陣列之方式排列。The rubber sleeve 420 includes a body 422, and the body 422 has a plurality of holes 424. When the rubber sleeve 420 is heat shrink coated on the capacitor element 410, the gas between the capacitor element 410 and the rubber sleeve 420 can be discharged from the hole 424. In the present embodiment, the holes 424 are arranged in an array.
圖5是依照本發明之第二實施例之一種電容器的立體示意圖。在本實施例之電容器500中，膠套520之本體522的孔洞524是以不規則的狀態排列。由圖4與圖5可知，此兩實施例的差異僅在於孔洞424、524之分布方式。當然，製造者可視情況調整孔洞424、524的分布方式以及尺寸大小。Figure 5 is a perspective view of a capacitor in accordance with a second embodiment of the present invention. In the capacitor 500 of the present embodiment, the holes 524 of the body 522 of the rubber sleeve 520 are arranged in an irregular state. As can be seen from FIG. 4 and FIG. 5, the difference between the two embodiments lies only in the manner in which the holes 424, 524 are distributed. Of course, the manufacturer can adjust the distribution and size of the holes 424, 524 as appropriate.
綜上所述，本發明之電容器及膠套直接在膠套之本體上設置孔洞，使得膠套不但仍可維持原有包覆電容器元件的功能，更可使得膠套熱縮包覆電容器元件時，電容器元件與膠套之間的氣體可自孔洞排出，以避免膠套變形而影響電容器之外觀。In summary, the capacitor and the rubber sleeve of the present invention directly provide a hole in the body of the rubber sleeve, so that the rubber sleeve not only maintains the function of the original cladding capacitor component, but also allows the rubber sleeve to shrink and cover the capacitor component. The gas between the capacitor element and the rubber sleeve can be discharged from the hole to avoid deformation of the rubber sleeve and affect the appearance of the capacitor.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，故本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
