Description

一种天线连接结构及其电子产品
技术领域
本实用新型属于通讯领域，特别涉及一种天线连接结构及其电子产品。
背景技术
NFC(Near Field Communication，近距离无线通信)移动支付技术现在越来越多的运用在手机上，为实现这一功能，组装上需要增加一个NFC天线，天线厚度为0.2-0.5mm左右。
目前NFC天线在手机上的组装方式有两种。第一种：将NFC天线贴在电池盖内侧上；另一种：将NFC天线贴在电池表面。
两种方式均使整机厚度增加0.2-0.5mm左右；且采用第一种方式长时间使用NFC天线容易脱落，可靠性差。采用第二种方式只能使用原装电池，不能使用第三方电池，使用受到限制。
实用新型内容
本实用新型的目的是提供了一种厚度小、结合牢固的天线连接结构。
本实用新型还提供一种电子产品。
为了实现上述目的，一方面是：
一种天线连接结构，包括天线及IML（In-Mould-Label，模内装饰成型技术)模片，所述IML模片上粘贴有所述天线，所述天线外围的IML膜片上设有注塑层。
结合第一方面，在第一种可能实现的方式中，所述天线四周的IML膜片上设有注塑层。
结合第一种可能实现的方式，在第二种可能实现的方式中，所述注塑层的厚度比天线的厚度大0.2~0.4mm。
结合第一方面，在第三种可能实现的方式中，所述天线的下表面及四周的4个面均设有注塑层。
结合第三种可能实现的方式，在第四种可能实现的方式中，所述天线的上表面设有注塑层，所述天线上表面的2个信号接触点裸露在所述注塑层外。
结合第一方面、第一种可能实现的方式、第二种可能实现的方式、第三种可能实现的方式及第四种可能实现的方式，在第五种可能实现的方式中，所述天线为近距离无线通信NFC天线。
结合第五种可能实现的方式，在第六种可能实现的方式中，所述NFC天线为硬板NFC天线。
另一方面是：
本实用新型还提供一种电子产品，包括所述的天线连接结构。
结合另一方面，在第一种可能实现的方式中，所述电子产品为手机。
本实用新型实施例提供的技术方案的有益效果是：
本实用新型采用IML模片上粘贴天线，消除了天线组装厚度，使产品的厚度小；在天线周围的IML模片上设置注塑层，在保证天线牢固固定的同时，保证了产品的强度。
附图说明
为了更清楚地说明本实用新型实施例的技术方案，下面将对实施例中使用的附图作一简单地介绍，显而易见地，下面所列附图仅仅是本实用新型的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本实用新型实施例提供的天线连接结构的结构示意图；
图2是本实用新型实施例提供的组装天线连接结构的流程示意图。
附图中，各标号所代表的组件列表如下：
1.天线；
2.IML模片，20.IML模，21.印刷层；
3.注塑层；
4.模具。
具体实施方式
为使本实用新型的目的、技术方案和优点更加清楚，下面将结合附图对本实用新型实施方式作进一步地详细描述。
参见图1，一种天线连接结构，包括天线1及IML模片2，IML模片2上粘贴有天线1，天线1外围的IML膜片2上设有注塑层3。
本实用新型在IML模片上粘贴天线，减小了产品组装的厚度，在IML模片与天线的结合处保证了产品的强度，在天线周围的IML模片上设置注塑层，保证产品的整个强度及天线与IML模片的结合力，使天线不易脱落，提高了使用可靠性。
本实施例是在上述实施例的基础上，天线1四周的IML膜片2上设有注塑层3。
本实施例仅在天线四周设置注塑层，将天线固定在IML膜片上。
本实施例是在上述实施例的基础上，天线1四周的注塑层3的厚度比天线1的厚度大0.2mm以上。优选为0.2-0.4mm之间。
本实施例注塑层3的厚度比天线1的厚度大，天线组装后，可增加天线5-10mm的识别距离。
本实施例是在上述实施例的基础上，天线1的下表面及四周的4个面均设有注塑层3。
本实施例的天线一般会设置在电池安装区，在注塑的过程中，塑件会将天线5个面都包裹，结合力会更好。
本实施例是在上述实施例的基础上，天线1的上表面也可以设有注塑层3，天线1上表面的2个信号接触点裸露在注塑层3外。
也可以采用天线全部被注塑层包裹，此时则需要将天线的2个信号接触点裸露出来，以便天线与手机主板接通。全部包裹结合力会很强，但同时会增加整体厚度，一般只包裹5个面，其结合力也会很好。
本实用新型的天线为NFC天线。优选硬板NFC天线。
硬板NFC天线可增加产品的整体强度。
本实用新型还提供一种电子产品，该电子产品中使用所述的天线连接结构。
该电子产品可以为手机。
参见图2，本实用新型的组装加工过程：
1)：使用业界通用的硬板NFC天线；
2)：先将NFC天线与IML膜片贴合；
3)：将贴合好的组件放在模具内注塑；
生产流程参见图2：
IML膜20上设有印刷层21，对设有印刷层21的IML膜20依次进行热压成型和冲贴，得到IML膜片2，然后IML膜片2与NFC天线1贴合，再将贴合后的产品放入到模具4中，模具4合模，模具4内注入塑胶，注塑成型，形成塑胶层3，最后模具4开模，产品取出，得到成品，即本实用新型的天线连接结构。
加工后的成品可以作为手机的后盖使用。
本实用新型具有以下的优点：
1、本实用新型设计上消除了NFC天线组装厚度，而且保证了产品的强度；
2、可增加NFC天线5-10mm的识别距离；
3、本实用新型中NFC天线为硬板，天线材料硬度比注塑层的塑胶要好，因此会增加整个天线结构形成壳体的整体强度，从而保证了产品的强度。
设计上用NFC天线替代部分塑胶，从而达到节省塑胶材料的目的。
4、NFC天线与IML膜片先贴合，后一起再做模内注塑，保证了NFC天线与IML膜片之间的结合力。
以上所述仅为本实用新型的较佳实施例，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
