Description

电感元件的连接结构
技术领域
本发明是有关一种连接结构,尤指一种电感元件的连接结构。
背景技术
请参见图1所示,其为相关技术的逆变器并网系统的电路方块图。如图1所示的逆变器并网系统系用以将直流电源Vdc,例如太阳能、风能…等再生能源所产生的直流电源,转换为交流电源Vac,以馈入交流电网使用。在直流电源Vdc,转换为交流电源Vac的过程,前级的直流对直流转换器11A用以调整直流电源Vdc的电压大小,例如使用升压转换器对直流电源Vdc升压。次级的直流对交流转换器12A用以将升压后的直流电源转换为交流电源。最后,再通过后级的滤波器13A对转换后的交流电源提供滤波,而得到可并入交流电网使用的交流电源Vac。
上述所使用的直流对直流转换器11A通常需要配合升压电感的使用,并且滤波器13A通常需要配合滤波电感的使用。然而,无论是升压电感或滤波电感除了提供升压与滤波的功用外,也是系统内产生不必要干扰的来源。
请参见图2A与图2B所示,分别为相关技术的电感器与电路板的组合剖视图与上视图。图2A与图2B所示为一种电感器20A与电路板10A连接的方式,电感器20A通过线材21A与电路板10A电性连接。在此种应用中,需要在电路板10A上破孔,使线材21A能够穿过电路板10A而与电路板10A进行电性连接的锁固。然而,由于需要将线材21A穿过电路板10A上的破孔,因此,不仅增加工序流程,也可能造成线材21A破损的可能性。
请参见图3A与图3B所示,分别为相关技术的电感器与电路板的另一种组合剖视图与上视图。有别于图2A与图2B所示的组合方式,为了避免在电路板10A上破孔,因此则需要通过将线材21A绕设的方式以达成电感器20A通过线材21A与电路板10A电性连接。然而,此种组合方式则因为增加线材21A的长度而造成成本的增加,且过长的线材21A亦造成额外的电能损耗。
此外,无论是图2A(图2B)或者图3A(图3B)所示电感器20A与电路板10A连接的方式,由于线材21A直接延伸于电路板10A上,因此长距离的布线方式,将使得线材21A流经的高频电流所造成的电磁耦合效应对设置于电路板10A上的电路元件的电磁干扰,使电源转换器的电磁干扰严重且降低整体效率。
发明内容
本发明的目的在于提供一种电感元件的连接结构,解决缩短线材长度降低材料成本以及降低电磁干扰的问题。
为达成前揭目的,本发明所提出的电感元件的连接结构,其包含电路基板、电感元件、支撑件、容置件、对位件、连接件及锁附件。电路基板具有通孔。电感元件具有至少一线材,且至少一线材非连接电感元件的一端具有固定端子。支撑件固定于座体上。容置件形成于支撑件上,提供容置空间。对位件容置于容置空间,具有对位部。连接件具有第一连接部与第二连接部,第一连接部与对位部对接,以夹固固定端子。锁附件具有锁附部,锁附部与第二连接部对接,以锁固于电路基板上。
藉由所提出的电感元件的连接结构,能够大幅地缩短线材长度降低材料成本以及降低电磁干扰。
为了能更进一步了解本发明为达成预定目的所采取的技术、手段及功效,请参阅以下有关本发明的详细说明与附图,相信本发明的目的、特征与特点,当可由此得一深入且具体的了解,然而所附图式仅提供参考与说明用,并非用来对本发明加以限制者。

具体实施方式
兹有关本发明的技术内容及详细说明,配合图式说明如下。
请参见图4与图5所示,其系分别为本发明电感元件的连接结构的第一实施例的立体分解图与组合剖视图。电感元件的连接结构(之后简称连接结构)包含电路基板10、电感元件20、支撑件30、容置件40、对位件50、连接件60以及锁附件70。电路基板10可系为印刷电路板(printed circuit board,PCB),或者其他可承载电路元件的板体。其中,电路基板10具有通孔11。电感元件20,例如电感器,其具有铁心及绕设于铁心上的线圈。其中,铁心的型态可为U型铁心、方块(Block)型铁心…或者其他型态。
电感元件20具有至少一线材21,其可为缆线(cable)线材。具体地,至少一线材21可通过引脚(未图示)连接铁心上的线圈,藉此引出电感元件20的输出电气参数,例如输出电压或输出电流。至少一线材21具有两端,其中一端系连接铁心上的线圈,另一端(即非连接电感元件20的一端)具有一固定端子22。在一实施例中,固定端子22系可为环型压接端子,其中,所记载的固定端子22不限制仅能为环型压接端子,亦可采用C型、U型或V型等端子。
配合参见图6所示,其为本发明电感元件的连接结构的第一实施例固定于座体上的组合剖视图。图6相较于图5最大的差异在于图6绘示出座体90。座体90系可为壳体的内底座,其中,内底座可为非导电或导电的材质。而座体90可使用压铸成型所制成,但不限于此。所述壳体用以装设电感元件20、电路基板10以及上述的该些元件。支撑件30设置于座体90上,承前所述,支撑件30系可设置于壳体的内底座的表面上。此外,可通过在壳体的空间内灌(注)胶,对电感元件20提供固定与散热的功效。
复见图4与图5,容置件40形成于支撑件30上,提供容置空间41。在不同的实施例中,支撑件30与容置件40系为一体成型或可分离地接合所形成者。举例来说,支撑件30与容置件40可以射出或压铸的方式一体成型,使得容置件40具有容置空间41,且容置件40形成于支撑件30上。或者,支撑件30与容置件40可为分开(可分离)形成的两件式结构,经接合后使得容置件40形成于支撑件30上。
对位件50容置于容置件40的容置空间41,且对位件50具有对位部51。如图4所示的实施例,容置件40的俯视横截面为六边形截面,对应地,对位件50的俯视横截面亦为六边形截面,藉此,对位件50可容置于容置件40的容置空间41。在一实施例中,对位件50系可为六角形螺帽,且不限定为塑料螺帽或金属螺帽。在其他实施例中,对位件50的俯视横截面亦可为其他边形截面或其他材质的螺帽,且容置件40亦对应对位件50的结构设计形成。
连接件60具有第一连接部61与第二连接部62。连接件60的第一连接部61与对位件50的对位部51对接,且穿设固定端子22,以夹固固定端子22,以本实施例而言,固定端子22为环型压接端子。如图4与图5所示的实施例,连接件60的俯视横截面为六边形截面,且第一连接部61外凸于连接件60的一端,具有外螺纹。对位件50的对位部51为内凹结构,承前所述,若以对位件50为六角形螺帽为例,对位部51则为六角形螺帽的内螺纹。因此,外凸于连接件60一端且具有外螺纹的第一连接部61系穿设过固定端子22,且与六角形螺帽的内螺纹(即对位部51)螺接。当第一连接部61与对位部51螺接紧固时,能够将固定端子22夹固于两者(第一连接部61与对位部51)之间。
锁附件70具有锁附部71。锁附件70的锁附部71与连接件60的第二连接部62对接,且穿设电路基板10的通孔11,以锁固于电路基板10上。如图4与图5所示的实施例,连接件60的第二连接部62为内凹结构,若以连接件60为六角柱体为例,第二连接部62则为连接件60(即六角柱体)另一端的内螺纹。锁附件70的锁附部71外凸于锁附件70的一端,具有外螺纹。在本实施例中,锁附件70系可为螺丝。因此,外凸于锁附件70一端且具有外螺纹的锁附部71穿设过电路基板10的通孔11,且与六角柱体的内螺纹(即第二连接部62)螺接。当锁附部71与第二连接部62螺接紧固时,能够将电路基板10夹固于两者(锁附部71与第二连接部62)之间,此时,锁附件70则锁固于电路基板10上。
请参见图7、图8与图9所示,其系分别为本发明电感元件的连接结构的第二实施例、第三实施例与第四实施例的局部立体分解图。该些实施例与图4(或图5)所示的第一实施例最大的差异在于对位件50的对位部51、连接件60的第一连接部61与第二连接部62以及锁附件70的锁附部71彼此对应匹配的结构不同。
具体地,图7所示第二实施例的对位件50的对位部51为内凹结构,因此对应匹配的连接件60的第一连接部61为外凸结构。再者,连接件60的第二连接部62为外凸结构,因此对应匹配的锁附件70的锁附部71为内凹结构。
具体地,图8所示第三实施例的对位件50的对位部51为外凸结构,因此对应匹配的连接件60的第一连接部61为内凹结构。再者,连接件60的第二连接部62为内凹结构,因此对应匹配的锁附件70的锁附部71为外凸结构。
具体地,图9所示第四实施例的对位件50的对位部51为外凸结构,因此对应匹配的连接件60的第一连接部61为内凹结构。再者,连接件60的第二连接部62为外凸结构,因此对应匹配的锁附件70的锁附部71为内凹结构。
综上,在上述所记载的对位部51、第一连接部61、第二连接部62以及锁附部71彼此之间四种不同连接实施例中,所记载的内凹结构不限制仅能以具有内螺纹的螺帽实现,亦即只要具有对接、锁合功能的内凹结构的部件,皆可作为具有内凹结构的对位部51、第一连接部61、第二连接部62以及锁附部71之用。同样地,在上述所记载的外凸结构不限制仅能以具有外螺纹的螺丝实现,亦即只要具有对接、锁合功能的外凸结构的部件,皆可作为具有外凸结构的对位部51、第一连接部61、第二连接部62以及锁附部71之用。换言之,只要能够达成对位部51、第一连接部61、第二连接部62以及锁附部71彼此之间对应匹配的内凹结构和/或外凸结构,皆可作为对位部51、第一连接部61、第二连接部62以及锁附部71之用。
请参见图10所示,其系为本发明电感元件的连接结构的第五实施例的组合剖视图。图10所示的第五实施例与图5所示的第一实施例最大的差异在于线材21自电感元件20延伸出的位置不同。后者(图5)所示的线材21连接于电感元件20远离对位件50(或连接件60、锁附件70)的一侧,即以图5的视角方向观之则为线材21系连接于电感元件20的左侧(即线材21系由电感元件20的左侧延伸至对位件50)。当线材21连接铁心上线圈的引脚较粗而不易弯折的情况下,图5所示的配置有利于缩小电感元件20与连接件60和锁附件70的距离,进一步可节省空间。相较于此,当线材21连接铁心上线圈的引脚容易弯折时,前者(图10)所示的线材21连接于电感元件20邻近对位件50(或连接件60、锁附件70)的一侧,即以图10的视角方向观之则为线材21连接于电感元件20的右侧(即线材21由电感元件20的右侧延伸至对位件50),藉此,通过线材21延伸自邻近对位件50的电感元件20一侧,可减短线材21的长度,以降低线材21的成本。
请参见图11所示,其系为本发明电感元件的连接结构的第六实施例的组合剖视图。图11所示的第六实施例与图6所示的第一实施例最大的差异在于支撑件30设置的位置不同。后者(图6)所示的支撑件30设置于铁心及绕设于铁心上的线圈之间,即电感元件20与支撑件30为接合的组装形态。相较于此,前者(图11)所示的支撑件30非设置于铁心及绕设于铁心上的线圈之间,即电感元件20与支撑件30非为接合的配置形态,即电感元件20与支撑件30为分离的配置形态。综上,支撑件30非限制仅能与电感元件20接合组装,可根据实际的应用状况,例如电感元件20的铁心形态不同或者可使用空间的大小…等,可改变支撑件30与电感元件20的组装形态。而电感元件20可使用例如U型铁心或方块(Block)型铁心,藉此,同样可达到电路基板10、电感元件20、支撑件30、容置件40、对位件50、连接件60以及锁附件70相对应的连接关系。
请参见图12所示,其为本发明电感元件的连接结构的第七实施例的组合剖视图。在此实施例中,电感元件的连接结构更包含金属板80。金属板80系设置于电路基板10与线材21之间,用以提供辐射屏蔽(radiation shielding),藉此大幅地降低线材21流经的高频电流所造成的电磁耦合效应对设置于电路基板10上的电路元件的电磁干扰。综上所述,本发明具有以下的特征与优点:
1、通过电感元件的连接结构,能够缩短线材长度降低材料成本、减少电能损耗。
2、通过电感元件的连接结构,能够降低电源转换器的电磁干扰严重,以提高整体效率。
3、对位部、第一连接部、第二连接部以及锁附部可为内凹结构和/或外凸结构,以增加匹配使用的设计便利性与多样性。
4、在容置电感元件的壳体空间内灌(注)胶,对电感元件提供固定与散热的功效。
以上所述,仅为本发明较佳具体实施例的详细说明与图式,惟本发明的特征并不局限于此,并非用以限制本发明,本发明的所有范围应以下述的申请专利范围为准,凡合于本发明申请专利范围的精神与其类似变化的实施例,皆应包含于本发明的范畴中,任何熟悉本领域的相关技术人员在本发明的领域内,可轻易思及的变化或修饰皆可涵盖在本发明所附权利要求的保护范围。
