具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1至图3所示，本申请实施例一提供一种线圈组件，该线圈组件包括线圈本体10、插针结构20和引线30，插针结构20的一端与线圈本体10电连接。引线30包括绝缘皮和多个导线，绝缘皮包裹在导线的外侧。引线30具有相对设置的第一连接端31和第二连接端，第一连接端31的导线与插针结构20的另一端电连接，且第一连接端31的导线与插针结构20的端部部分叠置，第一连接端31的导线与插针结构20在叠置的位置处固定连接。
应用本申请的技术方案，插针结构20的一端与线圈本体10电连接，插针结构20的另一端与引线30的第一连接端31的导线电连接，插针结构20的端部与第一连接端31的导线部分叠置，这样插针结构20与引线30的第一连接端31的导线直接连接。采用上述结构，能够增大二者连接的接触面积，保证插针结构20与引线30连接的稳定性，避免插针结构20与引线30在长时间工作后或因外力导致的接触不良。在现有技术中，插针结构20与引线30连接通常采用连接板或者端子和连接器等连接方式连接，这样会使得插针结构20在与连接板或者端子和连接器连接处的电阻偏大，导致连接处发热较快，提高了线圈组件被烧毁的风险，同时采用连接板或者端子和连接器等连接方式进行连接，生产工艺较多，所需零部件数量较多，提高了组装难度。并且在本申请中，将插针结构20与引线30直接连接，减少了生产工艺，其加工简单、便于组装，提高了装配效率。其中，一根引线30内包括多个导线，引线的一端与线圈本体10连接，引线的另一端与其他设备连接。
其中，线圈组件还包括连接件40，连接件40设置在引线30和插针结构20之间，且连接件40套设在第一连接端31与插针结构20叠置的位置处，插针结构20和引线30通过连接件40固定。如此设置，能够减少生产工艺和零部件的数量，同时能够保证引线30和插针结构20连接的稳定性，便于对线圈组件进行拆卸和安装，便于对线圈组件进行维修。
进一步地，一根导线包括多个线芯，多个线芯之间固定连接。如此设置，能够避免不同的导线之间彼此接触产生短路。可选地，可以采用锡焊方式先对多个导线进行预处理，将多个零散的导线固定为一体结构，在避免不同的导线之间彼此接触产生短路的同时，加工工艺简单，便于对线芯进行加工。
具体地，插针结构20包括插针21，插针21具有顺次连接的连接段211和折弯段212，连接段211和折弯段212之间具有夹角，连接段211与线圈本体10电连接，折弯段212与第一连接端31的导线电连接，连接件40套设在折弯段212和第一连接端31上。连接端和折弯段212之间具有夹角能够便于连接段211与线圈本体10电连接和折弯段212与第一连接端31的导线电连接，避免在连接过程中线圈本体10和引线30产生干涉影响线圈组件的正常运行，并且能够减小线圈组件的体积，便于线圈组件后续的安装与使用。
进一步地，插针21的表面设置有凹槽结构213，第一连接端31上的导线部分位于凹槽结构213内。其中，凹槽结构213的延伸方向可以插针21的延伸方向相同，也可以与插针21的延伸方向具有夹角，在本申请中凹槽结构213的延伸方向与相同。第一连接端31的导线与插针21连接时，第一连接端31的导线部分位于凹槽结构213内，如此能够增加第一连接端31的导线与插针21的连接强度，进一步地避免引线30与插针结构20接触不良。其中，插针21的横截面可以为圆形，也可以为多边形，在本申请中，插针21的横截面为圆形。
在本实施例中，插针21环形设置有多个侧面，每个侧面上均设置有凹槽结构213，如此能够使工作人员可选择地将第一连接端31的导线放置在其中一个凹槽结构213内进行固定。可选地，也可以在插针21上设置多个凹槽结构213，凹槽结构213与插针21的延伸方向垂直，工作人员将第一连接端31的导线与插针固定连接时，第一连接端31的导线部分位于凹槽结构213内，如此能够提高第一连接端31的导线与插针21的连接强度。
其中，折弯段212和连接段211相互垂直设置。如此便于对插针21加工制造，并且插针21的折弯段212和连接段211相互垂直设置能够增大插针21的适用范围，能够增大插针21的通用性。可选地，折弯段212的朝向可以根据实际适用情况确定，可以向上或者向下设置，也可以向左或者向右设置。
如图3所示，插针结构20包括多个插针21，多个插针21位于同一条直线上。这样便于对插针21进行安装，进而便于插针21和引线30进行电连接。
如图4所示，本申请实施例二提供了一种线圈组件，与实施例一不同之处在于：插针结构20包括第一插针21单元和第二插针21单元，第一插针21单元包括并排设置的多个第一插针21，第二插针21单元包括并排设置的多个第二插针21，多个第一插针21和多个第二插针21位于不同直线上，且多个第一插针21和多个第二插针21交错设置。第一插针结构20和第二插针结构20能够位于不同的直线上，这样能够避免第一插针21单元和第二插针21单元在与引线30连接时产生干涉，便于插针结构20与引线30进行电连接。
如图5所示，本申请实施例三提供了一种线圈组件，与实施例一不同之处在于：插针结构20包括多个插针21，多个插针21包括至少一个第一插针21和至少一个第二插针21，第一插针21的连接段211的长度大于第二插针21的连接段211的长度。如此能够进一步地避免第一插针21和第二插针21在与引线30连接时产生干涉，便于插针结构20与引线30进行电连接。其中，插针结构20内的插针21位置以及连接段211的长度可以根据实际使用情况进行确定。
如图6和图7所示，本申请实施例四提供了一种线圈组件，与实施例一不同之处在于：第一连接端31的导线与插针结构20在叠置的位置处采用压力焊或熔接焊焊接固定。可选地，第一连接端31的导线与插针结构20在叠置的位置处可以采用压力焊中的超声波焊接方式进行焊接。如此设置，导线和插针结构20进行超声波焊接时，焊接方式简单，焊接工艺容易实现，并且能够降低第一连接端31的导线与插针结构20在叠置位置处的电阻，提高叠置处的耐温度变化冲击性能，避免叠置处的温度过高而影响线圈组件的正常工作。同时采用上述结构，能够进一步地减少零部件的使用，降低生产成本，同时能够保证引线30与插针结构20连接的稳定性，避免引线30与插针结构20之间接触不良。其中，在本实施例中，插针结构20包括多个插针21，多个插针21位于同一条直线上。
进一步地，多个导线之间采用锡焊方式焊接固定。如此设置，采用锡焊方式对第一连接端31的多个导线进行预处理，将导线多个零散的芯铁固定为一体结构，避免不同引线的导线之间彼此接触产生短路。预处理后的导线再与插针结构20焊接，如此能够进一步地保证线圈组件的正常工作。
如图8所示，本申请实施例五提供了一种线圈组件，与实施例四不同之处在于：插针结构20包括第一插针21单元和第二插针21单元，第一插针21单元包括并排设置的多个第一插针21，第二插针21单元包括并排设置的多个第二插针21，多个第一插针21和多个第二插针21位于不同直线上，且多个第一插针21和多个第二插针21交错设置。第一插针结构20 和第二插针结构20能够位于不同的直线上，这样能够避免第一插针21单元和第二插针21单元在与引线30连接时产生干涉，便于插针结构20与引线30进行电连接。
如图9所示，本申请实施例六提供了一种线圈组件，与实施例四不同之处在于：插针结构20包括多个插针21，多个插针21包括至少一个第一插针21和至少一个第二插针21，第一插针21的连接段211的长度大于第二插针21的连接段211的长度。如此能够进一步地避免第一插针21和第二插针21在与引线30连接时产生干涉，便于插针结构20与引线30进行电连接。其中，插针结构20内的插针21位置以及连接段211的长度可以根据实际使用情况进行确定。
本申请实施例七提供了一种电子膨胀阀，该电子膨胀阀包括上述提供的线圈组件。采用上述线圈组件的电子膨胀阀能够避免引线30和插针21接触不良，保证电子膨胀阀的正常运行，同时工艺流程较短，生产成本较低。其中，线圈组件还包括外壳和灌封料，外壳与线圈本体10的外周固定连接，线圈本体10与外壳之间具有容纳腔，插针结构20位于容纳腔内，灌封料填充在容纳腔内，如此能够对插针结构20进行密封。
