Description
本發明係關於一種電子元件之部件,且尤其係關於一種感應線圈及其製造方法。
電子設備中常常需要具有磁心之感應線圈。使用該等感應線圈且將其裝配於元件之部件、印刷電路板或其他裝置中。常常在夾緊感應線圈且將其置放至所要位置之裝置的幫助下進行插入及附著過程。舉例而言,在置放之後,其可經自動焊接以建立電連接。
當在自動裝置之幫助下移動感應線圈時,可產生高速度,尤其是亦可產生急動加速度。歸因於急動加速度的產生,感應線圈磁心存在被擲出感應線圈繞組的危險。通常,感應線圈磁心實際上稍長於感應線圈繞組,但利用自動構件之夾緊通常發生在感應線圈之長度之中部,且因此發生在感應線圈繞組上。
為了允許夾緊感應線圈繞組,已知之為在亦可為封膠(DE 9410532)之黏著劑的幫助下將一塊塑料板附著於感應線圈繞組的頂側上。
本發明之任務在於設計一種尤其適合於自動組裝之電子元件之部件。
為了完成此任務,本發明提議一種具有如請求項1所述之特徵之元件的部件及/或具有如請求項11之特徵的方法。本發明之進一步實施例為附屬項之目標。
可藉由夾持器將元件固持於固持組件上且可將其移動至組裝點。
電子元件可(例如)為電容器。本發明尤其適合於安裝感應線圈。
通常,繞組彼此鄰近地位於感應線圈內部以便利用最小空間。根據本發明,提供為(例如)可在感應線圈之縱向方向上繞組之兩個部分之間或亦在兩個鄰近繞組之間的一點處獲得間隔。藉由此間隙,感應線圈磁心向外為自由的,以使得固持組件可連接感應線圈磁心與兩個鄰近感應線圈繞組。藉由在此點處射出成形而應用塑料固持組件。其變為與感應線圈磁心及兩個鄰近繞組相連接。以此方式在感應線圈磁心與感應線圈繞組之間提供一牢固連接以使得可不再發生先前所提及之困難。
對於自動組裝而言,所提供之感應線圈一般經設計以允許吾人識別出何感應線圈側預定組裝至印刷電路板上。吾人可(例如)識別出此側,因為感應線圈繞組之兩個連接端與感應線圈磁心成切線地伸展且位於單一平面中。本發明同樣提議固持組件應射出成形於感應線圈的相反側上,或換言之,提議自此側射出成形固持組件。以此方式導致亦有可能使用固持組件來形成用於夾緊裝置(例如,吸入管)的作用點。
根據本發明,在另一實施例中可提供為固持組件伸展過感應線圈之圓周的至少一部分。
在本發明之另一實施例中,可提供為固持組件僅伸展過感應線圈之長度的一部分。因此,感應線圈之剩餘部分尤其是感應線圈繞組仍然不受固持組件之材料的約束,以使得鑒於散熱能力而言並無任何限制。
亦可提供為固持組件延伸過感應線圈之整個圓周,以使得亦圍繞感應線圈而射出成形。
在本發明之另一實施例中,可提供為固持組件在線圈之遠離組裝側的側上呈現平表面。此平表面為吾人所需的且夾持器適合於作用於此平表面上。
根據本發明,亦可提供為自塑料射出成形固持組件,其中塑料在較高溫度下,例如在對應於焊接溫度之溫度下顯現出黏合作用。以此方式導致感應線圈額外地機械連接於另一點處,且同時由於焊接而產生其與印刷電路板的電連接。
對於製造感應線圈而言,本發明提議首先由導線製成感應線圈繞組以使得至少在兩個鄰近繞組之間之縱向方向上的一個點處呈現一間隙。隨後,將感應線圈磁心插入至此感應線圈繞組中並將包含感應線圈繞組及感應線圈磁心的單元插入至一注入模具中。可將感應線圈繞組與感應線圈磁心的許多類似單元插入至此注入模具中。此後,將固持組件射出成形於上文所提及之兩個繞組與兩個相鄰繞組之間的間隙上。
圖1展示具有例如由肥粒鐵製成之感應線圈磁心1的感應線圈。感應線圈磁心1配置為圓柱桿。其含有兩個平面表面2。感應線圈磁心1為感應線圈繞組3所圍繞,其展現為相互鄰近的複數個感應線圈繞組4。感應線圈繞組3之兩個末端5、6成切線地遠離感應線圈磁心1。兩個末端5、6可為更長的,圖示僅為示意性的。其位於一個平面內。此平面描繪感應線圈之組裝側。
感應線圈繞組3之繞組4捲繞於點7上以使得在感應線圈之縱向方向上出現間隔。藉此形成一間隙,藉由此間隙可看到感應線圈1之表面的一部分。
圖2展示自圖1之底部、因此自相移90°的方向所觀看到之圖1之感應線圈的視圖。在此,可觀看到兩個相鄰繞組4之間的間隔是如何形成的。在此點處繞組之梯度增大且最後再次減小至正常值。
圖1及圖2所描繪之包含感應線圈磁心1及感應線圈繞組3的單元隨後與複數個其他類似單元一起置放於一注入模具中。在此注入模具中,將固持組件8射出成形於感應線圈繞組3之兩個相鄰繞組4之間之間隔的點7上。圖3中可看到之固持組件8的頂側9為平坦的。在縱向方向上,固持組件8向下越過相鄰繞組之間的間隙且至少越過兩個相鄰繞組,較佳地達到鄰接繞組之間的凹陷處。固持組件8由塑料製成,且建立與磁心1及感應線圈繞組的接觸。所以,感應線圈繞組3亦與磁心1連接。在圖3之實施例的情況下,固持組件8在圓周方向上僅延伸過感應線圈之一部分。
圖4展示一實施例,其中固持組件18射出成形於感應線圈的整個圓周周圍。再次地,圖4下方之固持組件18之遠離組裝側的側具備平坦表面9,其中夾持器可作用於平坦表面9上。
在兩個實施例中,固持組件8、18僅延伸過感應線圈之長度的一部分,以使得感應線圈繞組3之剩餘繞組仍為自由的且可耗散熱量。
舉例而言,可概述為固持組件8、18借助於感應線圈附著至電子元件之部件。然而,此種固持組件亦可附著至其他電子元件之部件。
圖4所描繪之固持組件18可為射出成形塑料,其在對應於焊接溫度之溫度下顯現出黏合作用。若將感應線圈安裝至印刷電路板上且隨後焊接於其中,則其同時在固持組件18之幫助下結合至印刷電路板之表面。以此方式在印刷電路板上創建感應線圈之特別良好的機械安全性。借助於由在較高溫度下顯現出黏合作用的塑料製成的固持組件的此類連接亦可應用於其他電子元件之部件,而並非僅應用於具有感應線圈磁心的感應線圈中。
圖1至圖4所說明之用於感應線圈之水平配置的情形明顯地亦可用於感應線圈之垂直配置。在水平配置中,感應線圈磁心及感應線圈繞組之軸平行於其上附著有感應線圈的表面而運轉。在垂直配置中,此軸垂直於該表面而運轉。在垂直配置的情況下,同樣可能如圖1至圖3所示之對準固持組件。甚至,夾持器可夾緊固持組件之工作表面9並將感應線圈置放於所要位置及點處。
亦可能將固持組件附著至不同點處。此將參看圖5及圖6加以說明。圖5展示感應線圈之正視圖,其中可看到感應線圈磁心1之面表面2。此處之感應線圈繞組的兩個末端5、16以不同於先前實施例中所說明之方式配置。雖然連接端5仍與感應線圈磁心1成切線地伸展,但連接端16徑向向外伸展且自彼處向下彎曲,此參見圖6之側面圖。雖然圖5展示射出成形固持組件之前之具有感應線圈磁心的感應線圈,但圖6展示如此部分所示之已射出成形有固持組件28的側面圖。圖5中可看出,此處之感應線圈繞組之繞組4的部分經配置以使得其間之磁心1為自由的。因此,吾人可在此點處射出成形固持組件28,其隨後遠遠地向旁側延伸以使得達到頂端感應線圈繞組4。以此方式亦安全地固定感應線圈繞組3而使其不在磁心1上相移。
固持組件28可(例如)圍繞整個圓周覆蓋反向感應線圈的安裝表面,以使得其形成一類罩子。此固持組件28僅伸展過直徑範圍而超出表面端部亦可為足夠的,以使得左右兩邊仍保持為自由區域。
同樣在圖6所描繪之此類配置的情況下,若吾人意欲獲得與根據圖4之實施例相同的安裝類型,則類似於根據圖4之實施例的固持組件可延伸直至達到圖6中之下部面表面2上的一點處。
參看圖4至圖6所舉例說明之用於感應線圈之情形亦可應用於不同的電子元件之部件,例如應用於亦呈現連接端的電容器,此在夾持器之幫助下進行元件插入期間及焊接期間所發生的結合期間均為可能的。
