简介:随着科技的发展,手机的使用越来越普遍了。可是由于某些原因,手机通话的价格依然很高,这就使得大家不得不使用一些包月的方式来降低手机通话费用。同样,很多朋友在外地工作的时候也常常需要更换外地的手机卡以达到节省费用的目的。但是,常常更换手机卡不但麻烦,而且容易造成手机卡与手机接触不良造成手机损坏而不能使用!那么是不是就没有办法解决多个卡号切换的问题呢?答案是否定的,笔者在网上看见这样一套软件和设备可以将多个手机号码烧在一张SIM卡上,从而达到轻松切换
简介:摘要SIM卡连接器是一种供用户识别模块卡(SIM卡,SubscriberIdentificationModuleCard)插置的连接器,是手机中的重要连接器之一。由于手机越来越小型化、轻薄化,用户群体越来越大众化,生产越来越大量化,所以对手机使用的元器件,包括SIM卡连接器在内,在小型化方面提出越来越严格的要求。SIM卡的小型化也进一步的要求了SIM卡连接器的小型化和轻薄化,SIM卡连接器体积的减小对其端子的分布、耐用性等方面均提出了更高的要求。本文主要针对SIM卡连接器的技术发展路线,通过检索、统计、分析了SIM卡连接器的专利申请,重点梳理了重要申请人、技术分布等状况等信息,同时阐述了重点专利的技术发展脉络。
