附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

图2是本申请一种实施例提供的USB接口的内部结构图;
图3是本申请另一种实施例提供的USB接口的内部结构图;
图4是本申请另一种实施例提供的USB接口的内部结构图。
具体实施方式
为使得本申请的发明目的、特征、优点能够更加的明显和易懂,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而非全部实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
需要说明的是,本申请实施例中的充电适配器包括:电源适配器、充电器、IPAD、智能手机等能够输出电源信号以对电芯(移动终端的电芯)进行充电的终端。
需要说明的是,本申请实施例提供的串行总线(Universal Serial Bus,USB)接口可以是插座或者插头。该USB接口可以设置于电源适配器上,也可以设置于移动终端上,当该USB接口设置于移动终端上时,可用于数据传输和充电。为了实现大电流充电,该USB接口可支持包括具有至少两个插接部的电源线插舌和具有至少两个插接部的地线插舌的USB插头,进而使用本申请实施例提供的该电源线插舌和该地线插舌能够与该USB插头形成至少两个充电回路,实现3A以上的大电流充电。与此同时,该USB接口还可与现有的MICRO USB插头配合使用。
结合图1示出的本申请实施例提供的通用串行总线USB接口的结构示意图,同时结合图2示出的USB接口(未包含USB接口主体1和插接外壳2)的内部结构,需要说明的是,图1和图2仅为了示意本申请实施例提供的USB接口,从而只给出了具有两个插接部的电源线插舌、具有两个插接部的地线插舌、具有两个电源针脚以及具有两个地针脚的结构示意图。
本申请实施例提供的通用串行总线USB接口,包括:USB接口主体、用以外接电源线的电源线插舌、用以外接接地线的地线插舌,所述电源线插舌的底部和所述地线插舌的底部边缘固定于所述USB接口主体,所述电源线插舌包括P个插接部,且P大于或者等于2,所述地线插舌包括Q个插接部,且Q大于或者等于2;
所述电源线插舌还包括绝缘部,所述绝缘部使得所述P个插接部之间相互绝缘,和/或所述地线插舌还包括绝缘部,所述绝缘部使得所述Q个插接部之间相互绝缘。
另外,还需要说明的是,现有的移动终端常采用MICRO USB接口进行充电,由于该MICRO USB接口仅包含:具有一个插接部的电源线插舌、具有一个插接部的地线插舌、与电源线插舌相接的一个电源针脚、以及与地线插舌相接的一个地针脚,因此,现有的MICRO USB 接口只能通过一条电源通路和一条地通路形成的一路充电回路进行充电,从而只能最大支持3安培(A)的充电电流,因此,充电速度慢,浪费时间。
现有技术中为了提高充电速度,在现有的USB接口上设置具有至少两个插接部的电源线插舌以及具有至少两个插接部的地线插舌。从而在使用该USB接口充电时,能够同时通过电源线插舌中的多个插接部接收电信号,并通过多个电源针脚分担电流,能够支持3安培以上的大电流充电,但是当使用该USB接口连接普通的插头或者插座中的USB接口时,由于普通的插头或者插座中的USB接口的接插部的数量少于该USB接口中插接部的数量,使该USB接口中的部分接插部处于悬空状态,导致在传输电信号时电信号仍然会流经处于悬空状态的接插部出现输出端输出信号不稳定以及USB接口发热的现象。
因此,本申请为了解决上述技术问题,通过对现有MICRO USB接口(插座或者插头)进行改进后得到的USB接口,具有至少两个插接部的电源线插舌,具有至少两个插接部的地线插舌,并在电源线插舌的插接部之间或者地线插舌的插接部之间设有绝缘部。从而在使用该USB接口充电时,能够同时通过电源线插舌中的多个插接部接收电信号,并通过多个电源针脚分担电流,从而通过具有电源插舌和地插舌形成至少两个充电回路,能够支持3安培以上的大电流充电,并且在与普通的USB接口连接进行充电时,通过设置在电源线插舌的接插部之间或者地线插舌的接插部之间设置绝缘部,使正在通电的接插部与悬空的接插部之间处于绝缘状态,减少了流经正在通电的接插部的电流流过悬空的接插部导致的USB接口发热的现象。
另以图1和图2提供的USB接口为例,为了与快充接口进行对接,本申请实施例在现有USB接口提供的电源线插舌上增添一个插接部,设计制成时相当于增大了电源线插舌的底部的电流流过面积;同时为了增大了地线插舌的底部的电流流过面积,以在现有USB接口提供的地线插舌上也增添一个插接部;进而相对于现有的MICRO USB接口,电流流过面积增大后的电源线插舌3和地线插舌7,有效提高了最大能够承受的充电电流,其能够支持的充电电流比现有MICRO USB接口支持的充电电流大两倍及以上,满足大电流充电的需求。
另外以图1至图4提供的USB接口为例,在进行大电流充电(例如3A以上的充电电流)时,通过电源线插舌3的插接部31和插接部33与USB插头中对应的两条电源线连接以接收充电适配器通过该USB插头输出的大电流的电源信号;与此同时,通过地线插舌7的插接部71和插接部73与USB插头中对应的两条地线连接以形成大电流的充电回路,在进行普通充电时,仅通过电源线插舌3的插接部31和地线插舌7的插接部71进行充电,此时,为了防止电源线插舌3的插接部33和地线插舌7的插接部73处于悬空端时对流经的电流产生热量导致USB接口发热,可以采用以下几种方案,如图2所示,第一种方案是将电源 线插舌中的P个插接部之间设置绝缘部34,使P个插接部之间相互绝缘;如图3所示,第二种方案是将地线插舌Q个插接部之间设置绝缘部74,使Q个插接部之间相互绝缘;如图4所示,第三种方案是将电源线插舌中的P个插接部之间以及地线插舌Q个插接部之间均设置绝缘部34和绝缘部74;通过以上三种方案可以使该USB接口在与普通USB接口对接时,由于普通USB接口的接插部较少,例如通常为5个,该USB接口的接插部多于USB接口的接插部,当该USB接口与普通的USB接口连接时,该USB接口中与普通USB接口未连接的接插部处于悬空状态时,通过在电源线插舌的接插部之间或者地线插舌的接插部之间设置绝缘部,使正在通电的电源线插舌或者地线插舌的接插部与悬空的接插部之间处于绝缘状态,减少了流经正在通电的接插部的电流流过悬空的接插部导致的USB接口发热的现象。
优选的是,所述电源线插舌和所述地线插舌均采用磷青铜制成。值得说明的是,现有的用于对移动终端的电芯充电的MICRO USB接口中的电源线插舌和地线插舌均采用导电率不到20%的金属铜箔制成。然而,本申请实施例提供的USB接口所包含的所有电源线插舌和地线插舌均采用导电率能够达到50%的磷青铜制成;因此相对于现有的MICRO USB接口,本申请实施例提供的USB接口能够承受更大的充电电流。更优选的是,所述电源线插舌和所述地线插舌均采用磷青铜C7025制成。
优选的是,所述电源线插舌和所述地线插舌均采用铬青铜制成。由于本申请实施例提供的USB接口所包含的所有电源线插舌和地线插舌均采用导电率能够达到70%的铬青铜制成;因此相对于现有的MICRO USB接口,发明实施例提供的USB接口能够承受更大的充电电流。更优选的是,所述电源线插舌和所述地线插舌均采用铬青铜C18400制成。
优选的是,绝缘部34以及绝缘部74可以为设置在电源线插舌或者地线插舌的插接部之间的不导电的绝缘片、绝缘介质或者绝缘材料,绝缘材料可以为塑料、树脂以及有机化合物等。
在本申请另一实施例中,所述USB接口还包括:通过端子向移动终端中的电芯充电的电源针脚,用于形成对所述电芯充电的充电回路的地针脚;所述电源针脚为M个,M大于或等于2,每个电源针脚均与所述电源线插舌的底部相接;
和/或,所述USB接口还包括:与所述地线插舌底部相接的地针脚;所述地针脚为N个,N大于或等于2,每个所述地线插接部最多与1个地针脚电连接。
以图1和图2提供的USB接口为例,每个电源线插接部最多与1个电源针脚电连接,作为一种实施方式,每个电源线插接部与其同列的电源针脚电连接,两个电源针脚(电源针脚8和电源针脚9)分别与所述电源线插舌3的底部32相接,具体的,电源针脚8与电源插舌3的插接部33一一对应连接,电源针脚9与电源插舌3的插接部31一一对应连接, 从而通过电源针脚8和电源针脚9将从电源线插舌接收到的电源信号分两路传输以对移动终端的电芯充电。于此同时,作为同一个技术方案或者并列技术方案,每个地线插接部最多与1个地针脚电连接,两个地针脚(地针脚13和地针脚14)分别与所述地线插舌7的底部72相接,作为一种实施方式,每个地线插接部与其同列的地针脚电连接,具体的,地针脚13与地线插舌7的插接部71一一对应连接,地针脚14与地线插舌7的插接部72一一对应连接,移动终端的电芯的负极可在经过电路与两个地针脚形成电通路后,进而能够与两个电源针脚(电源针脚8和电源针脚9)、电源线插舌3以及地线插舌7一起作为对电芯充电的充电回路中的部分电路。
进而以此类推,根据对移动终端的电芯充电所需的充电电流,增添电源针脚的数量和地针脚的数量,形成至少两个对电芯充电的充电回路,有效减少功率损耗,减少发热,避免烧毁充电电路。
优选的是,每个电源针脚和每个地针脚均采用磷青铜制成。值得说明的是,现有的用于对移动终端的电芯充电的MICRO USB接口中的电源针脚和地针脚均采用导电率不到20%的金属铜箔制成。然而,本申请实施例提供的USB接口所包含的所有电源针脚和地针脚均采用导电率能够达到50%的磷青铜制成;因此相对于现有的MICRO USB接口,本申请实施例提供的USB接口在对移动终端的电芯进行充电时,能够支持更大的充电电流。更优选的是,每个电源针脚和每个地针脚均采用磷青铜C7025制成。
优选的是,每个电源针脚和每个地针脚均采用铬青铜制成。由于本申请实施例提供的USB接口所包含的每个电源针脚和每个地针脚均采用导电率能够达到70%的铬青铜制成;因此相对于现有的MICRO USB接口,发明实施例提供的USB接口能够承受更大的充电电流。更优选的是,所述电源线插舌和所述地线插舌均采用铬青铜C18400制成。
在本申请另一实施例中,电源线插舌3上设有绝缘部34时,电源线插舌3的绝缘部34形成在电源线插舌底部32,电源线插舌3的绝缘部34通过在电源线插舌底部3内填充绝缘介质形成;

作为本申请一实施例,当电源线插舌底部32中的绝缘部34或者地线插舌底部72中的绝缘部74在与快充USB接口连接进行快充充电时即充电电压值大于等于预设值时处于导通状态,当绝缘部34或者绝缘部74在与普通USB接口连接进行普通充电时即充电电压值小于预设值时处于绝缘状态,具体的,作为一种实施方式,绝缘部34或者绝缘部74可以为一种绝缘材料,具体的,该绝缘材料由纳米复合聚乙烯材料交联而成;纳米复合聚乙烯材料按质量份数计包括100份低密度聚乙烯、0.1-0.5份抗氧化剂以及0.1-3份纳米粒子,纳米粒子选自表面改性处理或表面未改性处理的纳米氮化硼,通过调节纳米粒子的含量进而调节绝缘部的导电率,其中,纳米粒子优选为2份,使其在普通充电时即充电电压较小时处于绝缘状态,在快速充电时即充电电压较大时处于导通状态,本实施方式通过设置绝缘材料的成分实现了不同充电电压的选择导通,在普通充电时绝缘材料处于绝缘状态,避免充电电流流经悬空端,在快速充电时处于导通状态,增大充电电流的流经面积;作为另一种实施方式,该绝缘部可以为绝缘片,在绝缘片中设置有继电开关,继电开关通过设置在绝缘片上的输入端和输出端连接两个区域,该继电开关在进行快充充电时即充电电压大于或者等于预设值时处于导通状态,以使绝缘片两侧的区域处于导通状态,可以实现电流流过面积增大,该继电开关在进行普通充电时即充电电压小于预设值时处于关断状态,以使绝缘片两侧的区域处于绝缘状态,可以实现进行普通充电时充电插接部与非充电插接部 之间的绝缘;作为另一种实施方式,该绝缘部可以为绝缘片,该绝缘片内设有控制器、弹簧开关以及导通部,控制器在进行快充充电时即充电电压大于或者等于预设值时控制弹簧开关推动导通部位于绝缘片中的空隙处,以联通绝缘片两侧的区域,使绝缘片两侧的区域处于导通状态,可以实现电流流过面积的增大,控制器在进行普通充电时即充电电压小于预设值时控制弹簧开关拉动导通部离开绝缘片中的空隙处,以隔断绝缘片两侧的区域,以使绝缘片两侧的区域处于绝缘状态,可以实现进行普通充电时充电插接部与非充电插接部之间的绝缘。

优选的是,所述电源线插舌3中长的插接部31、所述地线插舌7中长的插接部71、所述数据线正插舌5的插接部51、所述数据线插舌6的插接部61以及所述数据线负插舌4的插接部41均延插接方向伸出相等长度。
以图1和图2提供的USB接口为例,为了兼容现有的MICRO USB接口,以及提供良好的电接触,地线插舌7中长的插接部71、电源线插舌3长的插接部31、所述数据线正插舌5的插接部51、所述数据线插舌6的插接部61以及所述数据线负插舌4的插接部41为同等长度;优选的是,设计为现有的MICRO USB接口中插舌的插接部的长度。这样,将地线插舌7中长的插接部71、电源线插舌3长的插接部31、所述数据线正插舌5的插接部51、所述数据线插舌6的插接部61以及所述数据线负插舌4的插接部41设计得较长,并且设计为同等长度时,能够保证上述插接部均能与现有的MICRO USB接口进行良好的插接。实现良好的数据通信,以及实现电源信号和地信号的良好传输。
在本申请另一实施例中,所述电源线插舌中所有短的插接部和所述地线插舌中所有短的插接部均延插接方向伸出相等长度。
以图1和图2提供的USB接口为例,所述电源线插舌3中短的插接部33和所述地线插舌7中短的插接部73均延插接方向伸出相等长度。具体地,将所述电源线插舌3中短的插接部33和所述地线插舌7中短的插接部73向外延伸的长度设计得较短;从而,当与现有的MICRO USB接口进行插接后,所述电源线插舌3中短的插接部33和所述地线插舌7中短的插接部73均未与插接的针脚连接,处于空接状态,从而能够实现对现有的、标准的MICRO USB接口兼容。
在本申请另一实施例中,M个所述电源针脚的端子、所述数据负针脚的端子、所述数据正针脚的端子、所述数据针脚的端子以及N个所述地针脚的端子等间距排列。
以图1和图2提供的USB接口为例,电源线插舌3的插接部31插接部33、地线插舌7的插接部71和插接部73、所述数据线正插舌5的插接部51、所述数据线插舌6的插接部 61以及所述数据线负插舌4的插接部41的排列顺序固定后,两个所述电源针脚的端子(电源针脚8的端子82和电源针脚9的端子92)、所述数据负针脚10的端子102、所述数据正针脚11的端子112、所述数据针脚12的端子122以及两个所述地针脚的端子(地针脚13的端子132和地针脚14的端子142)的排序顺序也相应固定;同理,等间距排列的针脚的端子便于标准化生产及使用。优选的是,每两个相邻针脚所对应的端子之间的间距为:现有的MICRO USB接口中相邻针脚所对应的端子之间的间距。
更优选的是,M个所述电源针脚的端子、所述数据负针脚的端子、所述数据正针脚的端子、所述数据针脚的端子以及N个所述地针脚的端子依次等间距排列。
以图1和图2提供的USB接口为例,为了实现与现有的MICRO USB接口兼容,确定插舌的排列顺序后,也相应地确定了针脚的排列顺序为:电源针脚8的端子82、电源针脚9的端子92、所述数据负针脚10的端子102、所述数据正针脚11的端子112、所述数据针脚12的端子122、地针脚13的端子132以及地针脚14的端子142。
在本申请另一实施例中,针对位于边缘的电源针脚(本申请实施例提供的USB接口在现有MIRCO USB接口上新添的)和地针脚(本申请实施例提供的USB接口在现有MIRCO USB接口上新添的),可根据实际使用需要,设定每两个电源针脚之间的距离,以及设定每两个地针脚之间的距离;即设计出的每两个电源针脚之间的距离可不与现有等间距排列针脚的间距距离相等,设计出的每两个地针脚之间的距离可不与现有等间距排列针脚的间距距离相等。这样,在保证USB接口能够与现有MIRCO USB接口兼容的基础上,可以更改电源针脚之间的距离,以及更改地针脚之间的距离。
在本申请另一实施例中,与所述数据负针脚相邻的一个电源针脚的端子的底部宽度小于另外任一个电源针脚的端子的底部宽度;
与所述数据针脚相邻的一个地针脚的端子的底部宽度小于另外任一个地针脚的端子的底部宽度。
以图1和图2提供的USB接口为例,电源针脚8的底部宽度81大于电源针脚9的底部宽度91;地针脚14的底部宽度141大于地针脚13的底部宽度131。具体地,相对于现有MICRO USB接口提供的电源针脚,底部宽度较宽的电源针脚8为新添加的,用于:大电流充电时对大电流进行分流;由于该底部宽度较宽的电源针脚8主要用于大电流充电,从而为了分得大部分充电电流以及为了能够承受住大电流,将该电源针脚8的底部宽度设计的比现有的电源针脚9的底部宽些。
同理,相对于现有MICRO USB接口提供的地针脚,底部宽度较宽的所述地针脚14为新添加的,为了分得大部分充电电流以及承受住大电流,将新添加的地针脚14的底部宽度设计的比现有的地针脚13的底部宽些。
本申请实施例提供的USB接口,在现有的MICRO USB接口的基础上进行改进,具有至少两个电源针脚、至少两个地针脚、包含两个插接部的电源线插舌以及包含两个插接部的地线插舌,增加了导电面积以能够通过大电流,通过设计增加导电面积,至少能够支持3A及以上的充电电流;如果继续增大电源线插舌的底部和地线插舌的底部的导电面积,继续增加电源线插舌所具有插接部的个数,以及继续增加地线插舌所具有插接部的个数,能够支持更大的充电电流。更优的是,如果选用导电率更好的材质(例如磷青铜C7025或铬青铜C18400),可以相应减小电源线插舌的底部和地线插舌的底部的导电面积,或者提供能够支持更大的充电电流的USB接口。
优选的是,在本申请实施例提供的USB接口中,针脚(包括:每个电源针脚、所述数据负针脚、所述数据正针脚、所述数据针脚以及每个地针脚)和插舌(包括:所述电源线插舌、所述数据线负插舌、所述数据线正插舌、所述数据线插舌以及所述地线插舌)均采用工字型设计。这样,由于将本申请实施例提供的USB接口中包含的针脚和插舌采用工字型设计,能够与满足现有设计针脚和插舌的标准,实现对现有MICRO USB接口的良好兼容。
本申请实施例还提供一种移动终端,所述移动终端包括上述的通用串行总线USB接口。
通过该USB接口,可以提供大电流驱动其它的移动终端,以与其它移动终端进行通信;另外,还充电适配器还可以通过该USB接口对移动终端的电芯充电。
以上内容是结合具体的优选实施方式对本申请所作的进一步详细说明,不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说,在不脱离本申请构思的前提下做出若干等同替代或明显变型,而且性能或用途相同,都应当视为属于本申请由所提交的权利要求书确定的专利保护范围。
