可选地，连接段222通过端子22的一端翻边形成，工艺简单，节省焊接工序。
请参阅图2-图5，电子水泵还包括插座组件10，端子22与插座组件10连接，插座组件10穿设于后盖33中，端子22的内部开设有腔体221，腔体221的开口朝向插座组件10设置。
具体地，插座组件10包括插针11和插座12，插针11与插座12连接，并插入腔体221中，用于使插座12与端子22以及控制板20电路连接。
进一步地，插针11包括本体部113以及第一弯折部111，第一弯折部111连接于本体部113的一端，本体部113和腔体221的内壁抵接，第一弯折部111远离本体部113的一端抵靠于腔体221的内壁。如此设置，使得插针11卡接于腔体221内，采用插接接触的方式，连接牢固，装配简单，且避免了锡焊焊接容易产生的虚焊、焊渣飞溅等风险，从而降低了生产线的次品率，提高产品质量。
本体部113与第一弯折部111之间设有第一圆弧段，本体部与第一弯折部111之间通过第一圆弧段114连接。如此，能够缓解本体部113与第一弯折部111之间的应力集中问题，防止本体部113与第一弯折部111在长期使用过程而发生折断。
插针11还包括第二弯折部112，第二弯折部112一端与第一弯折部111连接，第二弯折部112远离第一弯折部111的一端靠近本体部113并与本体部113抵接，从而形成三角形的形状，当插针11受到横向的压力，第二弯折部112与本体部113之间的抵接能够在一定程度上抵抗压力，从而使三角形形状的插针11具备一定弹性，最终使插针11与腔体221的内壁抵接更为紧密。
第一弯折部111与第二弯折部112之间设有第二圆弧段110，第一弯折部111与第二弯折部112之间通过第二圆弧段110连接。同样地，如此设置，能够缓解第一弯折部111与第二弯折部112之间的应力集中问题，防止第一弯折部111和第二弯折部112在长期使用过程发生折断。
更进一步地，第二弯折部112包括第一段1121和第二段1122，第一段1121与第一弯折部111相连接，第二段1122连接于第一段1121远离第一弯折部111的一端，第二段1122至少部分侧面与本体部113贴合。如果第二弯折部112的端部直接与本体部113抵接，由于接触面积较小，两者之间压强较大，容易造成插针11磨损，并且，由于压强加大，第二弯折部112会直接戳住本体部113，从而影响插针11的弹性。在本申请中，第二弯折部112分成第一段1121和第二段1122，第二弯折部112通过第二段1122与本体部113贴合，增大了第二弯折部112与本体部113的接触面积，减少了两者之间摩擦产生的磨损，延长了产品的使用寿命，并且，至少部分第二段1122与本体部113平行，使得第二段1122能够沿着本体部113的侧面运动，对于整个第二弯折部112的运动起到导向作用。
在本实施例中，第一弯折部111和第二弯折部112均通过插针11弯折形成，无需新增部件，结构简单，成本低廉。在其他实施例中，第一弯折部111和第二弯折部112也可以通过部件依次焊接的方法形成，而不限于本实施例中弯折的方法。
第一段1121与第二段1122之间设有第三圆弧段1123，第一段1121与所述第二段1122通过第三圆弧段1123连接。不仅能够缓解两者之间的应力集中问题，而且，能够进一步防止第一段1121的端部戳住本体部113而影响插针11的弹性。
更具体地，第一弯折部111与本体部113的夹角α为锐角，第一弯折部111与第一段1121的夹角β为锐角，第一段1121与第二段1122的夹角γ为钝角，以此形成一个三角形结构，保证插针11良好的弹性，并且使插针11与腔体221紧密贴合，减少插针11的体积，保证电信号的传导。
在其他实施例中，各部件之间的角度也可以设置为：第一弯折部111与本体部113的夹角α为锐角，第一弯折部111与第一段1121的夹角β为钝角，第一段1121与第二段1122的夹角γ为锐角，只需要能够形成具有弹性的三角形即可，而不限于本实施例所述的角度设置方式。
在本实施例的电子水泵100的装配过程中，先将泵头31和泵壳32连接，然后将控制板20固定于泵壳32远离泵头31的一侧，再将插针11弯折成三角形，插入端子22的腔体221内部，与控制板20电连接，然后盖上后盖33，将后盖33与泵壳32螺纹连接，限位住插座组件10与控制板20。
相较于相关技术，本申请提供的电子水泵100，采用插接接触的方式，连接牢固，装配简单，且避免了锡焊焊接容易产生的虚焊、焊渣飞溅等风险，从而降低了生产线的次品率，提高产品质量。
如图8所示，本申请还提供一种热管理系统200，包括上述的电子水泵100。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
