Description

线缆接头 技术领域
本发明涉及电学技术领域，特别是涉及一种线缆接头。
背景技术
目前的电源适配器，一般具有直线I型和直角L型两种电源线接头。在接头和电源线的连接部分，一般会设计环状的橡胶加固结构，以增加该部分对反复弯曲导致材料疲劳的耐受性。但在实际使用中，由于主机和电源线的走向不确定性，导致无论采用哪种形状的接头，都有可能在接头和电源线的连接处产生异常或大角度的弯曲。
例如电源线走向和电源接头插入主机方向一致(平行)时，如采用L型的电源接头，在接头与电源线连接处会产生至少90度的异常弯曲。同理如果电源线走向与接头插入主机方向垂直，如果采用I型的直线接头，也会产生异常弯曲。上述情况，会大大影响线材的接触性能和使用寿命。
为了解决该问题，目前已有的设计包括在电源线接头处设计可替换的接头，以适应不同的环境或接头插孔形状。但该技术方案的缺陷在于附件较多，容易丢失，且会增加成本，无法做到一套方案适用多种情形。
发明内容
本发明实施例提供了一种线缆接头，以至少解决现有技术中一种接头不能适用多种使用场景的问题。
为解决上述技术问题，本发明提供一种线缆接头，所述线缆接头包括连接在一起的第一线缆和第二线缆；
其中，所述第一线缆与第二线缆之间的接触面为斜面；
所述第一线缆的接触面上设置有凹槽，凹槽内彼此绝缘的导电片分别与所述第一线缆内的各条导线连接；
在所述第二线缆的接触面上安装有转轴，所述转轴的下半部分插入所述第二线缆中，位于所述第二线缆之外的上半部分插入所述凹槽中；所述转轴上彼此绝缘的电极一端分别与所述凹槽中的导电片连接，另一端分别与所述第二线缆中的各条导线连接。
可选地，所述斜面与所述第一线缆和第二线缆之间的夹角均为45°。
可选地，所述转轴与所述第二线缆的接触面保持垂直。
可选地，所述转轴的下半部分包括彼此绝缘的内圈和外圈，其中，内圈和外圈分别与所述第二线缆的两条导线相连接。
可选地，所述转轴的上半部分包括两个凸起，每个凸起两侧的电极都分别与内圈和外圈连接。
可选地，所述第一线缆上凹槽包括两个插孔，所述插孔的形状与所述凸起的形状相同；所述插孔上设置两片有彼此绝缘的导电片，分别与所述凸起上的电极连接。
可选地，所述转轴的下半部分为一个导电插头，其中导电插头被绝缘体分割为多个电极，各个电极分别与所述第二线缆中的各条导线连接。
可选地，所述转轴的上半部分包括一个或多个凸起，每个凸起上彼此绝缘的电极都分别与所述转轴下半部分的电极连接；
可选地，所述第一线缆上凹槽包括一个或多个插孔，所述插孔上设置有彼此绝缘的导电片，分别与所述凸起上的电极连接。
可选地，所述插孔的形状与所述凸起的形状相同。
本发明有益效果如下：
本发明线缆前后两部分通过转轴和凹槽连接，使用时，通过旋转转轴，来调整前后两部分线缆之间的角度，可以保持水平，也可以保持垂直，适用于不同的使用场景，避免了单一接头不适合所有场景的缺陷，也克服了多种接头易丢、更换复杂、成本高等缺陷。

具体实施方式
以下对本发明进行进一步详细说明，应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
如图1所示，本发明实施例涉及一种线缆接头，
包括连接在一起的第一线缆10和第二线缆20；第一线缆10一端为接头端子102，另一端为与第二线缆连接的接触面；第二线缆20一端为电源线202，另一端为与第一线缆10连接的接触面。
其中，第一线缆10与第二线缆20之间的接触面为斜面；斜面与第一线缆10和第二线缆20之间的夹角均为45°；即：第一线缆10与第二线缆20之间的接触面与接头插入方向成45°角。
第一线缆10的接触面上设置有凹槽101，凹槽101内彼此绝缘的导电片分别与第一线缆10内的各条导线连接；
在第二线缆20的接触面上安装有转轴201，所述转轴201的下半部分插入第二线缆20中，位于第二线缆20之外的上半部分插入所述凹槽101中；所述转轴201上彼此绝缘的电极一端分别与所述凹槽101中的导电片连接，另一端分别与第二线缆20中的各条导线连接。第一线缆10(接头前部)可绕转轴201转动。
转轴201与第二线缆20的接触面保持垂直。
转轴201的下半部分与线缆的连接包括以下几种情况：
1、同轴电缆型：
转轴201的下半部分包括彼此绝缘的内圈和外圈，其中，内圈和外圈分别与第二线缆20的两条导线相连接。转轴201的上半部分包括两个凸起，每个凸起两侧的电极 都分别与内圈和外圈连接。第一线缆10的凹槽101包括两个插孔，插孔的形状与所述凸起的形状相同；插孔上设置两片有彼此绝缘的导电片，分别与凸起上的电极连接。
如图2所示，转轴201采用中空结构，内圈2012和外圈2011分别接通电源两级并互相绝缘，与接头前部(第一线缆10)的电极端子1011、1012分别接触，保证接头前部和后部电路畅通；接头前后部发生相对旋转时，仍能保电路的良好联通。
另外，与本实施例相似的，转轴201的下半部分与导线的连接也可以采用类似AV端子的方式进行连接，通过“莲花头(Radio Corporation of American)”接头的连接方式进行连接。
2、耳机插头型：
转轴201的下半部分为一个导电插头，其中导电插头被绝缘体分割为多个电极，各个电极分别与第二线缆20中的各条导线连接；第二线缆20设置为转轴插入的插孔也设置成从外到里彼此绝缘的多个电极，设置为与转轴连接。转轴201的上半部分包括一个或多个凸起，每个凸起上彼此绝缘的电极都分别与所述转轴201下半部分的电极连接；第一线缆10的凹槽101包括一个或多个插孔，所述插孔上设置有彼此绝缘的导电片，分别与所述凸起上的电极连接所述插孔的形状与所述凸起的形状相同。
如图3A、图3B所示，其中，A、B分别表示第一线缆10与第二线缆20处于水平状态时两个电极的连接情况；C、D分别表示第一线缆10与第二线缆20处于垂直状态时两个电极的连接情况。
接头前部绕与接头插入方向成45°角的转轴201旋转，转轴卡锁在接头前部的空腔内，并有一定阻尼。这样接头前部绕转轴旋转180°后，就可以与接头后部成90°角。接头完成了从I直线型到L直角形的变形。
如图4A、图4B所示，接头可以旋转成为I型或者L型以适应不同的主机摆放位置和线材走向，保证线材和接头处总体呈一直线，减少连接处线材异常和大角度的弯曲。降低长时间使用后对线材寿命的损耗和接触不良故障发生的可能性。
本发明用于带有电源线和插入主机的接头的电源适配器，如无线路由器，家庭网关或CPE(Customer Premise Equipment，客户终端设备)设备等。同时也可以将接头和旋转结构的尺寸修改后，应用于带有接头和线材的其它产品或场景，如手机充电器接头，耳机插头，USB(Universal Serial Bus，通用串行总线)或Mini USB(迷你USB)接头等。
尽管为示例目的，已经公开了本发明的优选实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本发明的范围应当不限于上述实施例。
工业实用性
如上所述，本发明实施例提供的线缆接头具有以下有益效果：适用于不同的使用场景，避免了单一接头不适合所有场景的缺陷，也克服了多种接头易丢、更换复杂、成本高等缺陷。
