相关申请的交叉引用
本申请主张在2014年7月1日在中国提交的中国专利申请号No.201410312557.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及移动通信技术领域，尤其涉及一种耳机插座及其应用的移动终端。
背景技术
现如今，为了提升用户语音通话以及媒体播放的品质，耳机插座已经成为了集成在移动终端的重要零件之一。然而，随着移动终端越做越薄，因机身空间较为有限，耳机插座一般均采取一体式的塑胶支架，这使得体积相对较大的耳机插座本体占用了机壳本体绝大部分空间，机壳已经没有足够的空间来保护耳机插座并对其进行结构支撑，传统的塑胶支架的耳机插座无法满足严苛的强度可靠性要求。如何在超薄移动终端上实现高强度可靠性的耳机插座成为一个亟待解决的问题。
发明内容
本公开的一个目的在于提供了一种耳机插座，其结构简单，具有高强度可靠性。
本公开所述的一种耳机插座的技术方案是这样实现的：
一种耳机插座，包括用于固定支撑耳机插头的第一插接件和第二插接件，所述第一插接件和/或第二插接件上设有用于固定所述耳机插座的安装部，所述第一插接件还包括一耳机插入口和由所述耳机插入口向内延伸形成的第一插入通道，所述第二插接件还包括设于第一插入通道延伸方向上的第二插入通道。
本公开的另一个目的在于提供了一种移动终端。
本公开所述的一种移动终端的技术方案是这样实现的：
一种移动终端，包括一移动终端本体和设于移动终端本体内的一耳机插座，所述耳机插座包括用于固定支撑耳机插头的第一插接件和第二插接件，所述第一插接件和/或第二插接件上设有用于固定所述耳机插座的安装部，所述第一插接件还包括一耳机插入口和由所述耳机插入口向内延伸形成的第一插入通道，所述第二插接件还包括设于第一插入通道延伸方向上的第二插入通道。
本公开所述的一种耳机插座及其应用的移动终端与现有技术相比具有如下优点：
1、通过将耳机插座由现有的一体式设计变更为包括第一插接件和第二插接件的分体式设计，不同的插接件可固定在移动终端的不同结构上，且各插接件均有各自的受力点对耳机插头进行有效的、单独的支撑，整体结构强度更高；
2、通过将耳机插座分体式设计，能在移动终端轻薄化的前提下有效的保证耳机插座的结构强度，适用范围较现有的一体式耳机插座更广，具有更好的应用前景。
