本申请基于申请号为201911046819.0、申请日为2019年10月30日的中国专利申请提出，并要求中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及一种智能电表及其载波模块。
背景技术
绝大多数的智能电表都安装有载波模块，做载波通信之用，而载波模块上装有导光柱。目前，单相智能电表上的载波模块上有两个如图1所示的导光柱1，为了制造方便，两个导光柱1是分开生产、安装的，两个导光柱1之间的距离是有要求的，所以需要专门的工序去控制，这样使作业效率比较低，并且使用自动化安装设备进行生产时，可能会产生定位不准确的问题。
授权公告号为CN103698566B，授权公告日为2016.09.21的中国专利公开了一种智能电表的一体化模块盒，该模块盒包括上盒、下盒和导光柱，导光柱设置在上盒的内部，上盒表面开设有抓取凹槽；导光柱两侧设有紧固凸台；该模块盒整体简洁大方，牢固可靠，能够很好满足智能电表对功能模块一体化及互换性的要求，但导光柱需要依靠其两侧的紧固凸台紧固，但是由于操作空间较小，安装紧固件操作不便，安装效率较低。
授权公告号为CN203298195U，授权公告日为2013.11.20的中国专利公开了一种导光柱排和导光结构，该导光柱排包括N个导光柱，其每一个导光柱都具有相同的形状，且布置为使得每一个导光柱的纵轴相互平行，且每一个导光柱的下端部都位于同一平面上N-1个筋条，其每一个否在同一水平上沿3导光柱的纵轴方向连接两个临近的导光柱，且使得N个导光柱连接为一个直线的导 光柱排。该导光结构能将多个导光柱制成一体式结构，使导光柱以较为简单的方式安装，节约装配时间、降低装配成本，减少错误出现的几率。
但是模块盒体安装导光柱的部分空间较小，在使用自动化装置或者是人工将导光柱安装到载波模块的过程中，这种结构的导光柱在安装时需要依靠每个导光柱以及连接导光柱的筋条进行定位，定位面比较多，定位面积较大，造成定位比较困难，且如果在导光柱的加工有偏差的情况下，安装时容易产生倾斜或是安装不上去的情况，影响装配速率。
发明内容

本申请通过在导光元件上设置定位凹槽或是定位凸起，在模块盒体上设置适配凸起或适配凹槽，使凹槽和凸起相互配合起到定位作用，减小定位面的面积，由此增加定位精度，避免了因导光元件的定位面面积较大而产生的定位困难的状况，使导光元件的插接安装过程比较简单。
作为本申请上述智能电表的进一步改进，所述导光元件上设有定位凹槽，所述模块盒体上设有适配凸起，所述适配凸起在导光元件插接方向的尺寸大于所述定位凹槽在导光元件插接方向上的尺寸。这样一来使导光元件和载波模块上的定位用的凹槽或凸起的加工比较简单，凸凹适配，结构比较合理，在将导光元件插接到模块盒体上的时候，首先是导光元件上的定位凹槽和模块盒体上的适配凸起相互配合，实现对导光元件的定位，由于定位面的面积较小，定位 精准且安装简单。
作为本申请上述智能电表的进一步改进，所述定位凹槽的与导光元件插接方向垂直的截面轮廓为三角形，所述适配凸起的与导光元件插接方向垂直的截面轮廓为三角形。这样一来，在对导光元件进行安装时，三角形的凸起或凹槽可以快速的对其进行定位，并且依靠定位凹槽和适配凸起的两个面进行定位，定位面比较少，定位面的面积较小，由此仅需保证导光元件和模块盒体的定位面的加工精度即可，降低了其余表面的加工精度要求，并且可以达到很好的定位效果。
作为本申请上述智能电表的进一步改进，所述导光元件的连接体上设有退料槽，所述退料槽位于与柱状导光体排列方向垂直的侧面。这样一来使毛刺集中在退料槽处，连接体其它各轮廓面的表面质量较好，在对导光元件进行插装时，不会因为表面的毛刺影响定位，影响安装效率。
作为本申请上述智能电表的进一步改进，所述退料槽的截面轮廓为矩形。这样一来，矩形的退料槽加工比较简单，且可以与定位用的定位凹槽区别开来。
作为本申请上述智能电表的进一步改进，所述模块盒体上设有用于与导光元件的连接体适配的卡槽。这样一来，模块盒体上的卡槽也可以与导光元件的连接体形成适配关系，虽然缝隙相对较大，但是在安装时可以对导光元件起到辅助的导向及定位作用，进一步的提高了定位的准确度。
作为本申请上述智能电表的进一步改进，所述连接体的轮廓为矩形，所述卡槽的轮廓为矩形。由此对连接体和卡槽的矩形的轮廓加工都比较简便。
作为本申请上述智能电表的进一步改进，所述定位凹槽设置在所述矩形的连接体的两侧，所述适配凸起设置在矩形的卡槽的两侧。这样一来，导光元件安装时由两侧定位，减少定位面的面积，增大定位精度。

具体实施方式
下面结合附图对本申请的实施方式作进一步说明。
本申请的载波模块的具体实施例1，如图2至图8所示，载波模块包括模块盒体2和设置在模块盒体2上的导光元件3，导光元件3包括两个导光柱34和与两个导光柱34固定连接的连接体32，连接体32的轮廓为矩形， 矩形的轮廓较便于加工且在安装时定位比较准确。两个导光柱34并排设置在连接体32的两侧，两个导光柱34沿连接体32的矩形轮廓的中心对称，连接体32的与导光柱34排列方向一致的两侧的侧面上设有两个对称的定位凹槽33，定位凹槽33的与导光元件3的插接方向垂直的方向上的截面形状为三角形，模块盒体2上设有供导光元件3的导光柱34穿过的穿孔22和用于与导光元件3的连接体适配的矩形的卡槽20，卡槽20的两侧设有用于与定位凹槽33适配的适配凸起21，同样的，适配凸起21的与导光元件3的插接方向的垂直方向上的截面形状也为三角形，三角形截面的定位凹槽33和适配凸起21使导光元件3在安装时定位面比较少，定位面的面积较小，由此仅需保证导光元件3和模块盒体2的定位面的加工精度即可，降低了其余表面的加工精度要求，降低加工难度，并且可以达到很好的定位效果。适配凸起21在导光元件3的插接方向的尺寸大于所述卡槽20在导光元件3插接方向上的尺寸。在将导光元件3插接到模块盒体2上的时候，首先依靠的是导光元件3上的定位凹槽33和适配凸起21进行定位，定位面较少，定位面积小，但定位精准且安装简单。
矩形轮廓的其余两个侧面的其中一侧的中间设有退料槽31，退料槽31为矩形缺口，退料槽31与连接体32的外轮廓的连接处设置有倒圆角，从而避免了连接体32上的应力集中，影响导光元件3的质量。退料槽31减少了生产过程中产生的毛刺，将毛刺集中在退料槽31处，降低了毛刺对导光元件3的性能的影响。导光柱34为一体式结构，包括设置在连接体32两侧的上部主体341和下部主体342两个部分，上部主体341和下部主体342为圆柱形，且上部主体341的轴线和下部主体342的轴线相重合，两个导光柱34的轴线相互平行，两个导光柱34的上表面和下表面在同一平面上。
