Description

带USB充电装置的墙壁电源插座 技术领域
本实用新型涉及一种电源插座，特别涉及一种带USB充电装置的墙壁电源插座。
背景技术
为了用电安全，世界各国对电源插座都制定了标准。对于单体墙式电源插座，在很多国家都规定了电源插座的外形尺寸，以及墙体内用于安装插座的预留空间尺寸。在欧标、法标或德标中，单体墙式电源插座的中间面板为55×55毫米，墙体内都会预先设置用于安装墙壁电源插座的直径65毫米左右、深度55毫米左右的圆柱筒。这样的每个单体墙式电源插座上只能设置一个用于连接用电器插头的电源插槽，且电源插座的中心与面板的中心基本重合。
现在移动电子设备日益普及，电子设备需要经常充电，随时携带电源适配器很不方便。如果在已经装修好的墙面再安装墙面USB充电插座，就需要另外在墙上挖洞、布线，会很麻烦。如果将现有的墙壁电源插座拆除，改装成USB充电墙壁插座，又会减少连接用电器插头的电源插槽，给日常工作和生活带来新的麻烦。
实用新型内容
本实用新型提供了一种带USB充电装置的墙壁电源插座，在不改变现有墙壁电源插座外形尺寸，也无需更换或增加墙体内预制的、用于安装电源插座的圆柱筒，也不减少原有的连接用电器插头的电源插槽的数量的情况下，解决上述问题。
根据本实用新型的一个方面，提供了一种带USB充电装置的电源插座，包括面板和与设于面板后侧的底盖；面板上设有电源插槽和USB充电插孔；面板与底盖形成的容置空间内设置有USB充电装置、火线金属片、零线金属片和地线金属片；USB充电装置包括USB接口，以及与USB接口连接的USB充电电路板；USB接口与USB充电插孔位置对应；电源插槽内分别设有与火线金属片、零线金属片和地线金属片的位置与形状对应的通孔；电源插槽中心与面板中心的距离为2～5毫米。
本实用新型的墙壁电源插座将电源插槽中心相对于面板中心的 偏移2～5毫米，在面板的一侧留出了设置USB插孔的位置，在面板与底盖形成的容置空间内、与USB插孔位置相应的一侧留出了安装USB充电电路板和USB接口的空间，使得增加了USB充电功能的墙壁电源插座的外形没有发生改变，可以直接替换那种仅设有连接外接用电器插头的电源插槽的墙壁电源插座，使单体墙壁电源插座也可以同时具备USB充电功能和给外接用电器供电的功能，更加适应现代生活的需要。
在一些实施方式中，本实用新型的电源插槽中心相对于面板中心向下的偏移量为2～5毫米；USB充电插孔设于电源插槽上方。电源插槽向下偏心，在面板的上部为USB充电插口留出设置空间。
在一些实施方式中，本实用新型的两个USB充电插孔分别水平设于面板上部的两个夹角处。USB充电电路板包括第一电路板和第二电路板，第一电路板与第二电路板呈L形连接，第一电路板位于底盖上侧面的内侧，第二电路板位于底盖后底面的内侧；第一电路板呈U形；两个USB接口分别设于第一电路板的两个自由端。这种设置充分利用了面板与底盖形成的容置空间中，由于电源插槽中心相对于面板中心下移而在火线金属片和零线金属片上定位成的空间，以及火线金属片和零线金属片后方的空间，就是有效利用了面板与底盖形成的容置空间上部和后部的空间，第一电路板呈U形，给可以给地线金属片留出安装位置，地线金属片的上部位于U形开口内，有效利用空间。
在一些实施方式中，本实用新型的第二电路板上设置有变压器、电容、工字电感、共模电感、IC芯片、Y电容和X电容，第一电路板上设置有固态电容。这些电器元件可以组成充电稳压滤波电路，使电子设备的充电过程更安全。这些体积较大的电器元件多集中安装在第二电路板上，可以充分利用火线金属片和零线金属片后方的空间。
在一些实施方式中，本实用新型的USB接口的输出为分别2100毫安和4200毫安。USB接口的输出电流大，可以实现快速充电。
在一些实施方式中，本实用新型的两个USB充电插孔分别倾斜地设于面板上部的两个夹角处；地线金属片上方设有整体呈“Π”形的USB支架；地线金属片与USB支架接触的部位设有相互适配的台阶；USB充电电路板包括相互连接的第一电路板和第二电路板；两个第一电路板分别与两个USB接口连接，分别倾斜地设于USB支架的上方两端；第二电路板上设有变压器，位于火线金属片和零线金属 片上方。这种设置可以有效利用面板与底盖形成的容置空间上部的空间。地线导电金属片既可以导电，也可以在USB支架和底盖间起连接作用，避免插座内部零件过多。台阶可以使USB支架与地线金属片的相对位置更稳定。
在一些实施方式中，本实用新型的第一电路板上设有定位通孔，USB支架上设有与定位通孔适配的定位凸块。这种设置可以使USB接口在被插拔时能够保持位置固定。
在一些实施方式中，本实用新型还包括套设于面板外侧的面框，面框的上边框的前沿设有挡片。当电子设备充电的时候，可以将其放置在面框上方，面框上的挡片可以避免其滑落。

具体实施方式
下面结合附图对本实用新型作进一步详细的说明。
图1～图4示意性地显示了根据本实用新型的一种实施方式的带USB充电装置的电源插座的结构。
如图1～图4所示，该墙壁电源插座为欧式规格，包括面板10，以及设置在面板10后方的底盖70。面板10的长度和宽度均为55毫米，底盖70的长度和宽度均为46.5毫米。插座的入墙深度为50毫米。面板10后设置有安装架20。
如图1和图2所示，面板10上设置了连接用电器插头的电源插槽11和两个USB充电插孔12。线aa为面板10的水平中线，线bb为电源插槽11的水平中线。线aa与线bb之间的距离D为3毫米。两个USB充电插孔12水平设置在电源插槽11的上方面板10的夹角处。
如图3和图4所示，面板10与底盖70形成的容置空间内的设置了USB充电装置，以及火线金属片51、零线金属片52和地线金属片53。USB充电装置包括USB充电电路板和两个USB接口61。两个USB接口61与面板10上的USB插孔12位置对应。
USB充电电路板包括第一电路板601和第二电路板602。第一电路板601与第二电路板602呈L形连接。如图4所示，第一电路板601位于底盖70上侧面的内侧，第二电路板602位于底盖后底面的内侧。第一电路板601呈U形。两个USB接口61分别设于第一电路板601的两个自由端。
第二电路板602上设置有IC芯片69、变压器64、两个电容68、工字电感67、共模电感66、Y电容62和X电容65；第一电路板601上设置有两个固态电容63。火线金属片51、零线金属片52和地线金属片53安装在支架40上。电源插槽11内分别设有与火线金属片51、零线金属片52和地线金属片53位置对应的通孔。
由于电源插槽11中心相对于面板10中心下移，火线金属片51、零线金属片52和地线金属片53也相应地整体下移，就在火线金属片51、零线金属片52和地线金属片53上方留出了空间。这种设置可以有效利用面板10与底盖70形成的容置空间上部和后部的空间。第一电路板601呈U形，可以给地线金属片53留出安装位置，地线金属片53的上部位于第一电路板601的U形开口内，有效利用空间。
在本实施例中，墙壁电源插座的电源插槽11的中心相对于面板 10中心的偏移量为3毫米，在面板10与底盖70形成的容置空间内留出了安装USB充电装置的空间，使得增加了USB充电功能的墙式电源插座的外形没有发生改变，可以直接替换那些仅设有连接用电器插头的电源插槽的墙式电源插座，可以使墙式电源插座同时具备USB充电功能和给外接用电器供电的功能，更加适应现代生活的需要。
在其它实施例中，电源插槽11的中心也可以根据需要相对于面板10的中心向下或向面板10的某一个夹角的偏移，偏移量D可以为2～5毫米。USB充电插孔12的数量也可以是一个或三个等。USB充电插孔12可以水平设置，或者以其它角度倾斜设置。
底盖70呈L形，通过螺钉与支架40连接。底盖70内设置了安装定位条72，便于安装固定第一电路板601。底盖70的四个角设置成圆角，便于在安装墙壁电源插座的时候旋转调节安装的角度。底盖70上设置了散热窗71，利于散热。
电源插槽11与火线金属片51和零线金属片52之间设有防误插保护装置90。
面板10通过螺钉与支架40连接。螺钉穿过防误插保护装置90和地线金属片53。
在本实施例中，USB接口61的输出为分别2100毫安和4200毫安。相对于USB接口61输出电流较小的电路里的电器元件，本实施例中的IC芯片69、变压器64、两个电容68、工字电感67、共模电感66、Y电容62和X电容65等电器元件的体积和功率都要大，而且高压电路与低压电路之间的距离要大于6毫米。所以，在本实施例中，更要合理安排电源插座的内部结构，给这些电器元件设置较大的空间。
如图5所示，当墙体内预先设置的用于安装电源插座的圆柱筒的深度比电源插座的厚度浅时，电源插座的面板10过于突出墙面，面板10的后表面不能与墙体接合，可以在面板10后方、安装架20的前方加装适当厚度的垫框80，用于填充面板10与墙体之间的缝隙，以适合墙壁内预先设置的圆柱筒的安装深度。
图6～8示意性地显示了根据本实用新型的另一种实施方式的带USB充电装置的电源插座的结构。
如图6和图7所示，该墙壁电源插座为欧式规格，包括面板10，以及设置在面板10后方的底盖70。面板10的长度和宽度均为55毫米，底盖70的最大高度为50毫米，宽度为52毫米，插座的入墙深 度为38毫米。面板10后设置有安装架20。面板10上设置了连接用电器插头的电源插槽11和两个USB充电插孔12。两个USB充电插孔12分别位于面板10的两个夹角处，并且呈45度左右的角度倾斜设置。
线aa为面板10的水平中线，线bb为电源插槽11的水平中线。线aa与线bb之间的距离D为3.5毫米。
面板10与底盖70形成的容置空间内的设置了USB充电装置，以及火线金属片51、零线金属片52和地线金属片53。USB充电装置包括USB充电电路板和两个USB接口61。两个USB接口61与面板10上的USB插孔12位置对应。
由于电源插槽11中心相对于面板10中心下移，火线金属片51、零线金属片52和地线金属片53也相应地整体下移，就在火线金属片51、零线金属片52和地线金属片53的上方留出了空间。
如图8所示，地线金属片53上方设有整体呈“Π”形的USB支架30。地线金属片53与USB支架30接触的部位设有相互适配的台阶31。台阶31可以使USB支架与地线金属片53的相对位置更稳定。地线金属片53既可以导电，也可以对USB支架30进行限位，避免插座内部零件过多。
USB支架30上设有两个通孔32，供外接用电器的插头的火线插杆和零线插杆穿过。电源插槽11与火线金属片51和零线金属片52之间设有防误插保护装置90。
图9示意性地显示了现有技术的地线金属片的结构。该地线金属片的两端形状与本实施例的一样，中段是平的。本实施例中对地线金属片53做了结构上的适应性修改。
USB充电电路板包括相互连接的第一电路板601和第二电路板602。两个第一电路板601分别与两个USB接口61连接，分别成45度左右倾斜地设于USB支架30的上方两端。第二电路板602上设有变压器64和其它电气元件，第二电路板602和变压器64位于火线金属片51和零线金属片52上方。
这种设置可以有效利用面板10与底盖70形成的容置空间上部和后部的空间。
在本实施例中，墙壁电源插座的电源插槽11的中心相对于面板10中心的偏移量为3.5毫米，在面板10与底盖70形成的容置空间内留出了安装USB充电装置的空间，使得增加了USB充电功能的墙式 电源插座的外形没有发生改变，可以直接替换那些仅设有连接用电器插头的电源插槽11的墙式电源插座，可以使墙壁电源插座同时具备USB充电功能和给外接用电器供电的功能，更加适应现代生活的需要。
第一电路板601上设有定位通孔，USB支架30上设有与定位通孔适配的定位凸块31。这种设置可以使USB接口61在被插拔时能够保持位置固定。在本实施例中，定位凸块61为8*8*4毫米的四棱柱状，在其它实施例中，也可以根据需要设置成三棱柱体，椭圆柱体等其它形状，以及其它规格。
面板10后方还设置了安装框20，安装框20上方内沿设有卡槽21，USB支架30的上沿设有与卡槽21适配的卡扣31。这种设置可以使USB支架30的位置更加稳定。
安装框20的内框尺寸为51*51毫米，可以避免USB接口61和面板10向内凹陷。
地线金属片53与底盖70固定连接，地线金属片53与面板10上的电源插槽30中心对应的位置设有内螺纹；电源插槽30的中心设有通孔13。可以使用与该内螺纹匹配的螺钉将面板10与地线金属片53连接，便于拆卸和安装面板10，检查插座内部情况。
图10示意性地显示了现有技术的火线导电金属片或零线导电金属片的结构。如图10所示，火线金属片51上用于连接外接用电器的插头的火线插杆插入的触点55是两个弧形相扣的结构，现有技术的火线金属片53的高度大约是触点55高度的两倍。
在本实施例中，为了在面板10与底盖70形成的容置空间内为USB充电装置留出更多的空间，缩短了火线金属片51的高度，同时将外接电源与火线金属片51的接触部位设置在后面，如图11所示。该结构同样适用于零线导电金属片。
本实施例中的结构也可以应用在法式或德式等规格的电源插座上，仅需要对插孔规格做相应的调整。
如图12所示，面板10的四角可以设置成圆角，以适合喜好圆角面板10的用户的需要。
图13所示，是本实用新型的结构用于法式电源插座的结构示意图，将地线金属片53改成法式规格的凸出的圆柱体状。
本实用新型的墙壁电源插座的面板10的外侧还可以设置面框14，面框14的上边框的前沿设有挡片141。当电子设备充电的时候， 可以将其放置在面框14上方，面框14上的挡片141可以避免电子产品滑落。该面框14的结构如图14所示。
以上所述的仅是本实用新型的一些实施方式。对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。
