下面参考图1-图7描述根据本申请第一方面实施例的插头组件100。
如图1-图7所示，根据本申请实施例的插头组件100，包括插头本体1和至少一个连接柱2。
插头本体1上形成有至少一个安装通孔10，连接柱2穿设在安装通孔10内，每个连接柱2的一端位于安装通孔10内以适于与压缩机201的接线端2011插接相连，每个连接柱2的另一端延伸至超出安装通孔10以适于与控制板101相连。
例如，如图1-图7所示，安装通孔10可以贯穿插头本体1的轴向两端，每个安装通孔10内可以穿设有一个连接柱2，连接柱2的一部分位于安装通孔10内、连接柱2的另外一部分伸出安装通孔10外，从而当插头组件100应用于压缩机启动器200时，连接柱2的位于安装通孔10内的一端可以与压缩机201的接线端2011直接插接相连，连接柱2的位于安装通孔10外的一端可以配合在压缩机启动器200的控制板101的安装孔内以与控制板101固定连接，方便了压缩机启动器200与压缩机201之间的连接，同时保证了压缩机启动器200与压缩机201之间的连接可靠性。
根据本申请实施例的插头组件100，通过在插头本体1上设置至少一个安装通孔10、并将连接柱2穿设在安装通孔10内，使得连接柱2的一端位于安装通孔10内、连接柱2的另一端延伸至超出安装通孔10，从而当插头组件100应用于压缩机启动器200时，连接柱2的上述一端可以与压缩机201的接线端2011插接相连、连接柱2的上述另一端可以与压缩机启动器200的控制板101相连，方便了压缩机启动器200与压缩机201之间的连接，保证了压缩机启动器200与压缩机201之间的连接可靠性。
在本申请的一些实施例中，安装通孔10为三个，三个安装通孔10呈三角形布置。例如，如图1-图5所示，在插头组件100的横截面上、依次用直线连接相邻两个安装通孔10的中心轴线的投影以形成三角形，使得插头本体1结构简单，便于插头组件100更好地与压缩机201的接线端2011相适配。
例如，在图1-图5的示例中，三个安装通孔10呈正三角形布置，也就是说，在插头组件100的横截面上、依次用直线连接相邻两个安装通孔10的中心轴线的投影以形成正三角形，从而简化了插头本体1的结构，便于插头本体1的加工，同时三个连接柱2呈正三角形布置，使得插头组件100更好地与压缩机201的传统的接线端2011相适配，提升了插头组件100的适用性。
在本申请的一些实施例中，如图1-图5所示，插头本体1包括彼此间隔开且平行设置的三个安装部11，三个安装部11可以呈三角形布置，每个安装部11上形成有沿安装部11的轴向贯通的一个安装通孔10。三个安装部11之间通过三个第一连接板12和三个第二连接板13相连，在插头本体1的轴向上、第一连接板12、第二连接板13和 安装部11的长度可以均相等。三个第一连接板12的一端相连且三个第一连接板12的上述一端与三个安装部11的中心连线所围成的三角形的内心重合，三个第一连接板12的另一端与对应的安装部11的外周壁相连，从而三个第一连接板12可以将三个安装部11相连，同时三个第一连接板12可以支撑相应的安装部11，以提高插头本体1的强度；相邻两个安装部11之间通过第二连接板13相连，即第二连接板13的一端与相邻两个安装部11中的其中一个相连、第二连接板13的另一端与相邻两个安装部11中的另外一个相连，三个第一连接板12位于三个第二连接板13和三个安装部11围成的图形的内侧。由此，进一步简化了插头本体1的结构，保证了插头本体1的强度。
例如，在图1-图5的示例中，三个安装通孔10呈正三角形布置，三个第一连接板12的一端相连且三个第一连接板12的上述一端与三个安装部11的中心连线所围成的正三角形的中心重合，从而保证了插头本体1的强度。
例如，如图1-图5所示，每个安装部11横截面的外轮廓形状为圆形，每个第二连接板13形成为朝向三个安装部11的中心连线所围成的三角形的内部凹入的弧形板，且每个第二连接板13与与其相连的两个安装部11分别相切，第二连接板13的外表面的一端可以与与其相连的两个安装部11中的其中一个的外周壁相切、第二连接板13的外表面的另一端可以与与其相连的两个安装部11中的另外一个的外周壁相切，使得第二连接板13与与其相连的两个安装部11之间圆滑过渡，使得插头本体1具有良好的持握感，便于用户的操作。
可以理解的是，每个第二连接板13还可以形成为平板，以简化第二连接板13的结构，同样方便了用户的操作。
例如，每个第一连接板12形成为平板，从而在保证插头本体1强度要求的前提下、进一步简化了插头本体1的结构，节省了插头本体1的用材量，降低成本。
在本申请的一些实施例中，如图1-图5所示，三个安装通孔10的中心轴线彼此平行，相邻两个安装通孔10的中心轴线之间的距离为x，x满足x＝11.6±0.5mm，也就是说，11.1mm≤x≤12.1mm，使得安装通孔10之间具有合适的加工精度，方便了安装通孔10的加工，同时由于压缩机201传统的接线端2011的三个接线柱中相邻两个接线柱的中心轴线之间的距离为11.66mm，使得插头组件100更好地与压缩机201的传统的接线端2011相适配，保证了插头组件100的通用性，同时插头组件100与接线端2011连接可靠，保证压缩机201的正常运行。
在本申请的一些实施例中，连接柱2包括同轴设置的第一连接柱21和第二连接柱22，安装通孔10包括同轴设置的第一安装孔10a和第二安装孔10b，第一连接柱21配 合在第一安装孔10a内，第二连接柱22的一部分配合在第二安装孔10b内、另一部分延伸超出第二安装孔10b，第一安装孔10a的外周壁位于第二安装孔10b的外周壁的外侧。例如，如图1-图7所示，安装通孔10可以形成为阶梯孔，第一连接柱21可以与第一安装孔10a相适配，第二连接柱22可以与第二安装孔10b相适配，第一连接柱21的外周壁可以位于第二安装孔10b的外周壁的外侧，当连接柱2自安装通孔10的一侧穿设在安装通孔10内时、无法自安装通孔10的另一侧穿出，从而当插头组件100应用于压缩机启动器200、第二连接柱22的伸出安装通孔10的一端与控制板101相连时，连接柱2可以限制插头本体1沿其轴向的移动，避免插头本体1与连接柱2脱离配合，保证了插头组件100的使用可靠性。
例如，如图4和图6所示，第一安装孔10a和第二安装孔10b均形成为圆形孔，以便于第一安装孔10a和第二安装孔10b的加工，其中第一安装孔10a的孔径为d，d满足d＝2.2±0.5mm，即1.7mm≤d≤2.7mm，使得第一安装孔10a具有合适的加工精度，第二安装孔10b的孔径小于第一安装孔10a的孔径；第一连接柱21和第二连接柱22的横截面分别与第一安装孔10a、第二安装孔10b相适配，使得第一连接柱21和第二连接柱22的外周壁均形成为圆形，第一连接柱21的外径为D，D满足D＝2.2±0.5mm，即1.7mm≤D≤2.7mm，第二连接柱22的外径小于第一连接柱21的外径，从而第一连接柱21具有合适的加工精度，且第一连接柱21可以很好地与第一安装孔10a配合，同时第一连接柱21可以更好地与压缩机201的传统的接线端2011相适配，保证了插头组件100的通用性。
在本申请的一些实施例中，如图6所示，第一安装孔10a的轴向长度为h，h满足h＝8.5±0.5mm，即8mm≤h≤9mm，使得第一安装孔10a具有合适的加工精度，同时压缩机201的接线端2011可以伸入第一安装孔10a内以与第一连接柱21插接相连，使得第一安装孔10a可以对第一连接柱21及压缩机201的接线端2011起到一定的保护作用，保证了压缩机201的接线端2011与连接柱2之间的连接可靠性。
例如，在图6的示例中，第一安装孔10a与第二安装孔10b之间形成有台阶部10c，台阶部10c上形成为凹槽10d，凹槽10d为环形且凹槽10d环绕第二安装孔10b设置，凹槽10d可以由台阶部10c的轴向一端的部分表面朝向台阶部10c的轴向另一端凹入形成，凹槽10d可以形成为筒状结构且凹槽10d可以与第二安装孔10b内外间隔设置，从而当插头组件100应用于压缩机启动器200以与压缩机201相连时，在装配过程中、连接柱2由于外力作用而相对于安装通孔10发生倾斜，此时凹槽10d发生变形使得连接柱2与安装通孔10可以不同轴设置。由此，通过在台阶部10c上设置环形凹槽10d， 凹槽10d的变形减小了连接柱2与安装通孔10之间的作用力，避免连接柱2与安装通孔10的作用力较大而损坏连接柱2或安装通孔10，有效保护了连接柱2和插头本体1。
在本申请的一些实施例中，如图6所示，在安装通孔10的径向上、凹槽10d的外周壁与第一安装孔10a的外周壁平齐，也就是说，在安装通孔10的横截面上、凹槽10d的外周壁的投影与第一安装孔10a的外周壁的投影的形状和大小均相同，从而方便了凹槽10d的加工。
可以理解的是，在安装通孔10的径向上、凹槽10d的外周壁还可以与第一安装孔10a的外周壁不平齐，例如，在安装通孔10的径向上、凹槽10d的外周壁还可以位于第一安装孔10a的外周壁的内侧，同样可以有效保护连接柱2和插头本体1。此外，凹槽10d可以与安装通孔10同轴设置、也可以与安装通孔10不同轴设置。
在本申请的一些实施例中，凹槽10d朝向第一安装孔10a敞开。例如，在图6的示例中，凹槽10d的背向第一安装孔10a的一侧封闭、且凹槽10d的朝向第一安装孔10a的一侧敞开，从而凹槽10d的朝向第一安装孔10a的一侧可以相对于第一安装孔10a发生一定的移动以使凹槽10d发生变形，保证凹槽10d的变形可以减小连接柱2和安装通孔10之间的作用力
其中，凹槽10d的横截面形状、大小及凹槽10d的轴向深度均可以根据实际情况具体设置，以更好地满足实际需求。
在本申请的另一些实施例中，凹槽10d朝向第一安装孔10a的一侧封闭、且凹槽10d背向第一安装孔10a的一侧敞开，从而凹槽10d的背向第一安装孔10a的一侧可以相对于第一安装孔10a发生一定的移动以使凹槽10d发生变形，同样可以保证凹槽10d的变形可以减小连接柱2和安装通孔10之间的作用力。
在本申请的一些实施例中，连接柱2的一端敞开以形成插槽21a，插槽21a的外周壁上形成有至少一个开口槽21b，开口槽21b贯穿插槽21a的外周壁。例如，如图3和图7所示，插槽21a可以由连接柱2的上述一端的部分端面朝向连接柱2的上述另一端凹入形成，压缩机201的接线端2011可以插接在插槽21a内；开口槽21b也可以由连接柱2的上述一端的部分端面朝向连接柱2的上述另一端凹入形成，开口槽21b可以自内向外贯穿插槽21a的外周壁且开口槽21b与插槽21a连通，由于压缩机201的接线端2011插接在插槽21a内而使开口槽21b发生变形，使得开口槽21b的沿连接柱2周向的相对两侧壁之间的距离增大，从而接线端2011可以紧密配合在插槽21a内，使得接线端2011与插槽21a之间自动扣紧，提高了连接柱2与压缩机201接线端2011之间的连接可靠性，同时便于压缩机201的接线端2011插接在插槽21a内，提高了装配效率。
例如，如图3和图7所示，开口槽21b为两个，两个开口槽21b沿连接柱2的径向相对设置，使得连接柱2的上述一端形成沿连接柱2的径向相对设置的两个锁紧件211。当压缩机201的接线端2011插接子在插槽21a内时，两个锁紧件211之间的距离增大，使得接线端2011紧密配合在插槽21a内、并将接线端2011与插槽21a之间自动扣紧，保证连接柱2与压缩机201接线端2011之间连接可靠。
可以理解的是，开口槽21b还可以为一个、三个、四个等，当开口槽21b为多个时，多个开口槽21b可以沿连接柱2的周向间隔设置；其中，当开口槽21b为两个时，两个开口槽21b还可以不沿连接柱2的径向相对设置。
在本申请的一些实施例中，连接柱2的一端具有导向部21c，导向部21c的横截面积沿连接柱2的轴向先减小、再增大。例如，在图3和图7的示例中，导向部21c可以大致形成为筒状结构，该筒状结构的横截面积沿连接柱2的轴向先减小、再增大，使得导向部21c的端部形成喇叭口，当插头组件100应用于压缩机启动器200时，便于压缩机201的接线端2011的接线柱插接在第一连接柱21内。
在本申请的一些实施例中，插头本体1的邻近控制板101的一侧设有至少三个凸台14，凸台14的自由端与控制板101相止抵。例如，如图2、图3和图6所示，凸台14可以由插头本体1的邻近控制板101的一侧的部分表面沿插头本体1的轴向凸出形成，当插头组件100应用于压缩机启动器200时，凸台14的自由端的端面与控制板101相止抵，实现了插头组件100相对于控制板101的定位，便于插头组件100与控制板101快速连接；同时由于凸台14的自由端的端面与控制板101相止抵，使得插头组件100与控制板101之间形成的接触面较为平整，避免了插头组件100和控制板101的表面不平整而导致插头组件100与控制板101之间的作用力较大，减小了插头组件100和控制板101的应力变形；而且，由于凸台14的自由端的端面与控制板101相止抵，插头本体1的邻近控制板101的一侧表面与控制板101之间间隔设置，有助于控制板101的散热，保证压缩机启动器200的可靠运行。
这里，需要说明的是，“插头组件100与控制板101之间形成的接触面”是指至少三个凸台14的自由端所共同限定的平面。其中，每个凸台14的高度为t，t满足t≤0.6mm，使得凸台14具有合适的高度，避免了凸台14过高而增加插头组件100的占用空间。其中，每个凸台14的高度可以相等、也可以不完全相等；t可以等于0，也就是说，此时插头本体1的邻近控制板101的一侧没有设置凸台14。
例如，如图2、图3和图6所示，每个凸台14均位于插头本体1的边缘，两个凸台14之间的距离可以较大，从而凸台14可以较好地支撑插头本体1，使得插头组件100 与控制板101相连时、插头本体1具有良好的稳定性。
根据本申请第二方面实施例的压缩机启动器200，包括控制板101和插头组件100，控制板101上设有控制电路1011，插头组件100为根据本申请上述第一方面实施例的插头组件100，插头组件100的连接柱2的另一端与控制板101相连。当压缩机启动器200与压缩机201相连时，控制电路1011可以控制压缩机201的启动。其中，压缩机启动器200可以为电子式启动器，可以降低压缩机启动器200的功耗。
根据本申请实施例的压缩机启动器200，通过采用上述的插头组件100，便于将压缩机启动器200快速与压缩机201相连，同时保证了压缩机启动器200与压缩机201之间的连接可靠性。
根据本申请第三方面实施例的压缩机组件300，包括压缩机201和压缩机启动器200，压缩机201具有接线端2011，压缩机启动器200为根据本申请上述第二方面实施例的压缩机启动器200，插头组件100与接线端2011插接相连。
根据本申请实施例的压缩机组件300，通过采用上述的压缩机启动器200，方便了压缩机组件300的组装，提高了压缩机组件300的组装效率。
根据本申请实施例的压缩机组件300的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。

例如，如图1-图7所示，连接柱2包括同轴设置的第一连接柱21和第二连接柱22，第一连接柱21的后端与第二连接柱22的前端相连，第一连接柱21形成为中空结构以使第一连接柱21的前端形成插槽21a，第二连接柱22可以形成为实心结构或中空结构，第二连接柱22的后端形成有导引面221，导引面221大致形成为圆台面，以便于连接柱2穿设在安装通孔10内。安装通孔10形成为阶梯孔且安装通孔10包括同轴设置的第一安装孔10a和第二安装孔10b，第一安装孔10a和第二安装孔10b均形成为圆形孔，第一安装孔10a的孔径d＝2.2±0.5mm，即1.7mm≤d≤2.7mm，第一安装孔10a的轴向长度h＝8.5±0.5mm，即8mm≤h≤9mm，第一连接柱21配合在第一安装孔10a内，第一连接柱21的外径D＝2.2±0.5mm，即1.7mm≤D≤2.7mm，第二连接柱22的前端配合在第二安装孔10b内、第二连接柱22的后端延伸超出第二安装孔10b，第一安装孔10a的孔径大于第二安装孔10b的孔径。

例如，如图2、图3和图6所示，插头本体1的邻近控制板101的一侧设有三个凸台14，每个凸台14均位于对应安装部11的后端的边缘，且每个凸台14的外表面与对应安装部11的部分外周壁平齐；每个凸台14的高度t≤0.6mm，凸台14的自由端的端面形成为平面且当插头组件100应用于压缩机启动器200时、凸台14的自由端的端面 与控制板101相止抵，此时第二连接柱22的后端穿设在控制板101的安装孔内以与控制板101焊接相连。
