背景技术Background technique
充电器一般包括用于交流转直流的充电座以及与充电座插接的充电线。The charger generally includes a charging base for alternating current to direct current and a charging cable that is plugged into the charging base.
目前许多的充电座均使用USB母座,只需要将充电线的USB插头插入 USB母座中就可以为手机等终端进行充电。参见图1,根据标准,现行的USB 母座一般包括用于接地的母座金属壳体101,母座金属壳体101的底部设有向上翘起的接地弹片1011。母座金属壳体101的内部设有第一母座PIN针102、第二母座PIN针103、第三母座PIN针104和第四母座PIN针105。其中:第一母座PIN针102常用于提供稳定的直流电压,第二母座PIN针103常用作数据传输负极管脚,第三母座PIN针104常用作数据传输正极管脚,第四母座PIN针常用于接地。参见图2,现行的USB插头包括插头金属壳体201,插头金属壳体201内依次设有与第一母座PIN针102对应的第一插头PIN针 202、与第二母座PIN针103对应的第二插头PIN针203、与第三母座PIN针 104对应的第三插头PIN针204和与第四母座PIN针105对应的第四插头PIN 针205。At present, many charging bases use USB sockets, and terminals such as mobile phones can be charged only by inserting the USB plug of the charging cable into the USB socket.

当前的USB母座与USB插头插接时具有方向性,即只有当插头PIN针和母座PIN针相对时,USB插头才能插入USB母座中,此时第一母座PIN针 102与第一插头PIN针202接触连接、第四母座PIN针105与第四插头PIN 针205接触连接,第一母座PIN针102、第一插头PIN针202、待充电的电子设备、第四插头PIN针205和第四母座PIN针105依次串联以形成充电回路。如果USB插头的上下方向与USB母座不对应,则USB插头会与USB母座相互干涉,于是出现USB插头无法插入USB母座中的情况。因此,在进行USB 插头与USB母座之间的插接之前,往往需要先分别观察一下USB插头和USB 母座的方向,再以正确的方向将USB插头插入USB母座中,显然,必须要先观察然后才能正确插入的对接方式十分麻烦。The current USB socket is directional when it is inserted into the USB plug, that is, the USB plug can be inserted into the USB socket only when the PIN pin of the plug and the PIN pin of the socket are opposite to each other. The
因此,需要对现有的充电器进行改进,以解决传统插头不能正反双向插入传统母座中的问题。Therefore, the existing charger needs to be improved to solve the problem that the traditional plug cannot be inserted into the traditional female socket in both directions.

需要说明的是,本实用新型提供的充电插头、充电线及充电器,一方面,不在舌板301的外围设置插头金属壳体201,有利于舌板301可以正反双向插入USB母座的插入空间中,解决了传统插头反向无法插入传统母座中的结构干涉问题;另一方面,充分利用第一母座PIN针102和接地弹片1011在USB 母座的容置槽中一上一下中心对称布置的现有条件(具体地,第一母座PIN 针102位于容置槽的左上角,接地弹片1011位于容置槽的右下角),将第一导电端子302和第二导电端子303分别固定在舌板301的正反面,只要适当控制第一导电端子302和第二导电端子303的位置就可以使得充电插头正面朝上和背面朝上插入插入空间中均可实现与USB母座的电连接,解决了传统插头反向插入无法与传统母座电导通的电路导通问题。因此,本实用新型提供的充电插头可以正反双向插入USB母座中并能实现充电功能。It should be noted that, in the charging plug, charging cable and charger provided by the present invention, on the one hand, the
