Description

可正反方向对插的USB插头 技术领域：
本实用新型涉及电连接器技术领域，尤其涉及一种可正反方向对插的USB插头。
背景技术：
USB(Universal Serial BUS，通用串行总线)，是一个外部总线标准，用于规范电脑与外部设备的连接和通讯，是应用在PC领域的接口技术。USB接口支持设备的即插即用和热插拔功能。当今用于数据传输与数据交换的外设接口中，通用串行总线接口(USB)无疑是在计算机及周边电子消费品领域应用最为广泛的接口之一。计算机周边外设绝大多通过USB连接计算机进行数据传输与交换，如鼠标、键盘，U盘、打印机，手机、相机等等。那么就需要在计算机上安装USB插座，在计算机周边外部设备上安装插头，连接时插头***插座，使两者产生电连接。目前，用于手机、平板电脑等便携式移动设备的传输通讯、充电通电等连接器接口中，微型通用串行总线(MICRO USB)接口连接器已经被广泛应用。
由于插头插座本身设计电连接点是一一对应的，插错了会造成无效甚至将设备烧坏等重大危险。为了防止人们在使用USB接口对接时插错，USB接口特意进行了防呆设计，即插头、插座会因为其单面对插的特性而需要对准方向才能插进去，这就需要浪费很多的检查 和校对的时间。这样，用户在使用时，往往需要查看插座是哪一方向的，再将插头调整到同一方向再***，或者一插不对换个方向再插，有时换来换去还会因为硬插用力过猛把插头或插座给插坏了，造成很***烦。
实用新型内容：
本实用新型的目的就是针对现有技术存在的不足而提供一种能够正反两面任意插到USB插座上的可正反方向对插的USB插头。
为了实现上述目的，本实用新型采用的技术方案是：

所述插芯的上下两端面上每排导电端子各为4根，插芯上端面由左到右第1根、第2根、第3根、第4根导电端子分别依次与插芯下端面由右到左第1根、第2根、第3根、第4根导电端子一一对应连接。
所述绝缘本体尾端固定有电路板，各个导电端子的后端分别与电路板电连接。
所述插芯上下两端面中对应连接的导电端子之间为一体成型结构。
所述插芯上下两端面中对应连接的导电端子的后端连接在一起， 其中，插芯下端面对应导电端子的前端向前引出到插芯下端面，插芯上端面对应导电端子的前端先向后引出再弯折到插芯上端面。
所述插芯上端面导电端子的弯折处上方盖设有盖子，盖子卡合在绝缘本体上端面上。
所述绝缘本体通过一体注射成型方式与导电端子结合成一体结构。
各个导电端子的前端均嵌入在插芯中，导电端子前端向外侧凸起形成导电凸部，位于插芯上端面的导电端子的导电凸部凸伸出插芯上端面，位于插芯下端面的导电端子的导电凸部凸伸出插芯下端面。
所述金属壳体向内凹陷形成有多个卡点，卡点紧压绝缘本体将绝缘本体固定在金属壳体内。
所述金属壳体的上下端面和两侧面上均设有卡点。
本实用新型有益效果在于：本实用新型的可正反方向对插的USB插头包括有金属壳体、设置在金属壳体内的绝缘本体、导电端子，绝缘本体的前端凸伸出有插芯，插芯的上下两端面各设置一排导电端子，插芯上端面的导电端子按由左到右的顺序分别依次与插芯下端面的导电端子按由右到左的顺序一一对应连接，本实用新型的插芯双面都能进行电连接，使得插头从正反任一方向***插座均能有效电连接，使用方便，不会出现方向插错的现象，有效保护插头和插座，连接简单方便，耐用，提高操作效率。

具体实施方式：
下面结合附图对本实用新型作进一步的说明，见图1～4所示，本实用新型的可正反方向对插的USB插头，包括有金属壳体1、设置在金属壳体1内的绝缘本体2、导电端子3，绝缘本体2的前端凸伸出有插芯21，插芯21的上下两端面各设置一排导电端子3，插芯21上端面的导电端子3按由左到右的顺序分别依次与插芯21下端面的导电端子3按由右到左的顺序一一对应连接，使得插头从正反任一方向***插座均能正确电连接。
插芯21的上下两端面上每排导电端子3各为4根，插芯21上端面由左到右第1根、第2根、第3根、第4根导电端子3分别依次与插芯21下端面由右到左第1根、第2根、第3根、第4根导电端子3一一对应连接，以实现当正面***时第1根导电端子3与反面***时的第1根导电端子3正确连接在同一端子位上。

绝缘本体2为耐高温耐磨材料，绝缘本体2通过一体注射成型方式与导电端子3结合成一体结构，从而将导电端子3固定在绝缘本体2上，保证导电端子3不松动，长期插拨使用不会破坏导电端子3结构，适合于大量自动化生产，成本低，性能好。
各个导电端子3的前端均嵌入在插芯21中，导电端子3前端向外侧凸起形成导电凸部31，位于插芯21上端面的导电端子3的导电凸部31凸伸出插芯21上端面，位于插芯21下端面的导电端子3的导电凸部31凸伸出插芯21下端面。
金属壳体1的上下端面和两侧面上均向内凹陷形成有多个卡点11，卡点11紧压绝缘本体2将绝缘本体2固定在金属壳体1内，以克服装配中因制造公差所产生的配合间隙，达到绝缘本体2与金属壳体1紧密结合并保持对称，使得对插母座连接器***时，无论从哪一面***都是一样的力度。
本实用新型的插芯21双面都能进行电连接，使得插头从正反任一方向***插座均能有效电连接，使用方便，不会出现方向插错的现象，有效保护插头和插座，连接简单方便，耐用，提高操作效率。
作为本实用新型的另一实施方式，见图5～7所示，与上一实施方式不同的是，插芯21上下两端面中对应连接的导电端子3的后端连接在一起，其中，插芯21下端面对应导电端子3的前端向前引出到插芯21下端面，插芯21上端面对应导电端子3的前端先向后引出再 弯折到插芯21上端面。制作导电端子3时，下端面导电端子3的从前端引出，上端面导电端子3从后端引出，与绝缘本体2结合后再将上端面导电端子3向前弯折到插芯21上端面，结构简单，加工和装配方便。插芯21上端面导电端子3的弯折处上方盖设有盖子5，盖子5卡合在绝缘本体2上端面上。
绝缘本体2为耐高温耐磨材料，绝缘本体2通过一体注射成型方式与导电端子3结合成一体结构，从而将导电端子3固定在绝缘本体2上，保证导电端子3不松动，长期插拨使用不会破坏导电端子3结构，并且将上端面导电端子3空出来，然后将上端面导电端子3前端向前弯折到插芯21上端面，再在弯折处的上方盖上盖子5。
当然，以上所述仅是本实用新型的较佳实施例，故凡依本实用新型专利申请范围所述的构造、特征及原理所做的等效变化或修饰，均包括于本实用新型专利申请范围内。
