所述护套主体上包括有至少一个插针套；护套主体上插针套的数量不多于该绝缘护套对应的插头的插针数量。上述结构根据不同插头对插针套需求的不同，能够带有不同数量的插针套，主要保护容易漏电的或漏电危害较大的插针，主要能够有效保护火线和零线。
所述插针套内的插针孔的形状对应于插头的插针。根据不同规格的插针定制成与之相匹配的插针套的形状和大小，保证绝缘护套的紧密性和安全性。
插头的插针包括圆插插针、扁插插针、棱柱型插针；比如：单项两级扁插、单项两级带接地扁插、英式插头的插针、或美式插头的插针、英式插头的插针、或美式插头的插针、欧式插头的插针、南非标准插头、澳大利亚标准插头。上述列举较为大众的几种共用插头，但不仅仅限于上述型号的插头插针的样式。
所述护套主体的两面分别为正侧面和背侧面，插针套设于护套主体的正侧面，在护套主体的背侧面的边缘设置有凸起于护套主体背侧面的护边。上述护边的结构能够将绝缘护套更加紧密的包裹在插头的绝缘部分上，有效的提高密封性，保证防水性和防触电性。
设于护套主体背侧面的护边呈环形、齿型或爪型，该护边用于紧密包裹在插头的绝缘部分上。上述结构能够根据插头的绝缘部分的不同进行固定，从而提高绝缘防护套的兼容性。
护边凸起于护套背侧面的凸起高度不小于1mm；护边的厚度不小于0.05mm；在护边的内侧壁上设置有凸条。该结构的凸起能够向插头的绝缘侧翻起，更有效的防止水从绝缘护套和插头的橡胶部分之间进入，影响其安全性和防水性。
护套主体的背端面与插头的绝缘部分紧密贴合，插针套紧密包裹于插头的插针的根部；护套主体的正端面和背端面分别为护套主体相对的两面。上述结构将护套主体制作的平整，使护套主体的背端面与插头的绝缘部分贴合的更加紧密，有效的保证绝缘护套的防水性。
插头的插针凸起于插头的插针安装面上；插针套设于护套主体的正端面，护套主体的背端面与插头的橡胶部分紧密贴合。上述结构是将背端面贴合在插针的安装面上，由于该面较为平整，与背端面贴合后具有更好的贴合效果，有效的提高防水性。
插针从护套主体的背端面经过插针孔穿入、从插针套的自由端穿出并漏出金属部分，该金属部分的长度不少于插针长度的30％。上述结构时插头的金属部分漏出，且该漏出的位置刚好为插头与插座中导电的位置，在有效的提高防水性的同时，不影响插头的导电性。
所述护套主体的背端面设置有粘连层，在粘连层上覆盖有用于保护其粘连性的薄膜层，该薄膜层可取下。上述结构的粘连层进一步的提高了护套本体的贴合程度，提高护套主体防水性。
所述粘连层呈膜状覆盖护套主体背端面上，或者粘连层由多个相互间隔的环状构成；该粘连层的厚度不小于0.05mm。该粘连层及其布局能够防止护套主体发生褶皱时产生的造成密封性和防水性降低的情况。
所述护套主体和插针套为一体成型的整体。该一体成型的结构能够有效的提高绝缘护套的防水性，降低身产的难度和生产时间，降低生产成本。
所述护套主体和插针套为组合式结构，护套主体上设置用于安装插针套的安装孔，在插针套一端的侧面设置凸起，该凸起用于与护套主体配合安装。该组合式的绝缘主体能够有效的提高设备的自由度，能够根据插头的实际情况选择合适的、匹配的护套主体和插针套，能够方便使用者的使用。
所述护套主体和插针套具有绝缘性、耐压性、耐磨性、刚性、耐高温、和韧性。
所述护套主体和插针套的耐压电阻值不小于200兆欧，耐压值不小于5kv，耐高温程度不小于300℃。

具体实施方式
下面结合附图，对本实用新型作详细的说明。
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型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实用新型，并不用于限定本实用新型。
具体实施例1：
如图1-4所示，本实用新型的一种用于双孔插头4的插头的绝缘护套，包括护套本体1和插针套2，护套本体1呈片状，该片状的护套本体1的两面分别为正端面和背端面；插针套2连接在护套本体1上，该插针套2垂直于护套本体1的正端面；插针套2的中部设置有用于装配插针的插针孔3，该插针孔3穿过插针套2与护套本体1的连接处并分别连通插针套2的自由端和护套本体1的背端面，插针套2分为火线插针套21和零线插针套22，在火线插针套21和零线插针套22的中部设置的插针孔3分别为火线插针孔31和零线插针孔32；护套本体1的正端面平整，插针套2凸起于护套本体1的背端面，其插针套2的凸起高度不小于2mm或者其凸起的高度不小于使用该绝缘护套的插针高度的10％。
护套本体1和插针套2采用一体成型的工艺在300℃以上高温条件下制成，其耐高温程度不小于300℃，护套本体1的厚度不小于插针套2的厚度；插针套2和护套本体1的厚度不小于0.05mm；或者，当插针为国标的扁插插针时，插针套2和护套本体1的厚度不小于插针厚度的10％，当插针不为国标的扁插插针时，插针套2和/或护套本体1的厚度不小于插针厚度的5％且大于0.05mm。
护套本体1和插针套2采用绝缘，耐压，耐磨，高刚性，耐高温的材料制成，其电阻值不小于200兆欧，耐压值不小于5kv；可以采用PI材料或者聚氨酯材料制备该绝缘护套。
该绝缘护套在使用时，将其安装在国标插头的插针根部，插针设置并凸起于插头的插针安装面上，护套本体1的背端面紧密贴合到插头的插针安装面；插头的插针穿过插针套2中部的插孔，使插针套2紧密套设在插针的根部，插针的自由端超出插针套2并漏出插针的金属部分，其漏出的金属部分至少为插针长度的30％。当相匹配的绝缘护套安装到双孔插 头4上时，火线插针套21套设到火线插针41上，零线插针套22套设到零线插针42上；或者，可以仅将一根插针套设插针套2，另一根插针不套设插针套，同样能起到防触电的效果。
为了增加护套主体与插针安装面的紧密程度，可在护套主体的背端面设置0.05-0.5mm厚的粘连层，并在粘连层上覆盖薄膜层，该薄膜层能够保护粘连层不被氧化或不会降低其粘连性，同时，薄膜层也不会与粘连层粘连到一起使该薄膜层能够被取下；该绝缘护套在使用时，将薄膜层取下，然后将插针套2套设到插针的根部，然后将护套主体的背端面通过粘连层粘连到插针安装面上，形成密封。粘连层可均匀涂抹到护套主体的背端面上，也可以将粘连层呈环状的涂抹到背端面形成以一定间距隔开的多层的粘连环。
具体实施例2：
如图5-8所示，本实用新型的一种用于双孔插头4的插头带护边的绝缘护套，包括薄片状的护套本体1和凸起于护套本体1正端面的插针套2、以及插针孔3，插针可依次穿过护套本体1和插针套2并超出插针套2的自由端漏出插针金属部分。在护套主体上具有至少一个插针套2(一般为三个)，插针孔3位于插针套2的中部，并连通插针套2的自由端和护套本体1的背端面，护套本体1的背端面与正端面相对；插针套2凸起于护套本体1正端面的高度不小于3mm，一般为4-5mm。插针孔3可选为圆孔或方孔或扁平孔，其插针孔3的具体形状和位置分别于国标插头的插针位置相对应。在护套本体1的边缘设置有用于凸起于背端面的护边，该护边可为环状或齿状，该护边用于紧密套入插头的侧面以加强防水防漏电的效果。其护边凸起大于护套本体1背侧面的高度为1-5mm；护边的厚度一般不小于0.05mm。
护套本体1和插针套2可采用实施例1中的一体成型工艺制成一体式结构，另外，护套本体1和插针套2也可以采用组合式结构，即插针套2可拆卸的装配到护套本体1上，在护套本体1与插头的插针相对应的位置设置有安装孔，该安装孔用于安装插针套2；在插针套2的连接端的侧面设置有凸起，插针套2从护套本体1的背侧面插入安装孔中，将凸起贴合到护套本体1上，以便于实现按需要选择合适的插针套2配合，以便于实现世界各国的不同标准的插头。
此外，在护套本体1的背侧面同样可以采用实施例1中的粘连层和薄膜层的结构，以提高绝缘护套的防水性和防漏电性。绝缘护套采用具体实施例1中的材料制成。
具体实施例3：
如图9-12所示，本实用新型的一种三孔插头的绝缘护套，包括片状的护套本体1、插针套2和插针孔3，护套本体1具有正端面和背端面，插针套2凸起护套本体1的正端面上，且其 凸起高度一般为插针长度的10％-60％(一般采用40±5％)，插针套2的位置与三孔插头的插针位置相对应，插针套2包括火线插针套23、零线插针套25和地线插针套24；在插针套2中部设置有插针孔3，该插针孔3连通插针套2的自由端和护套主体的背端面，插针孔3包括火线插针孔33、零线插针孔34和地线插针孔35，并分别对应安装到插头的火线插针51、零线插针53和地线插针52上；插针孔3和设置为不同的形状分别对应于不同国家标准的插头，比如：扁插插针的插头，圆插插针的插头，方插插针的插头，英式插头，美式插头等。
该绝缘护套的插针套2可具有不同的长度，以便于区分插头的各个插针，同时，也可以仅仅设置火线和零线的插针套2，而不设置地线的插针套2，以便于减小绝缘护套的体积。该绝缘护套的材料可使用实施例1中的具有绝缘，耐压，耐磨，高刚性，高韧性的材料(比如具有这些特性的塑料材料)。
如图13-20所示，该用于三孔插头5的绝缘护套可以采用实施例2中的护边结构，其护边可以呈环形或者呈刺形，呈齿形或者爪形反扣到插头的侧面，以便于加强绝缘护套的防水性和防漏电性。该用于三孔插头5的绝缘护套可采用实施例1中的粘连结构和薄膜层结构，有效的加强绝缘性。
该绝缘护套不仅仅限于用于双孔插头4和三孔插头5，同样可适用于四孔或具有更多数量插针的插头，此外，插针孔3的形状和位置以及插针套2的位置根据插头的插针位置不同而不同，并且插针孔3的形状和位置对应于插头的插针。
该绝缘护套在使用时，将插头的插针对应穿过绝缘护套的插针孔3，并从插针孔3的另一端漏出至少40％的金属部分，护套主体的背端面贴紧插头的插针安装面；护套主体的护边反扣到与插针安装面相邻的侧面上，并利用护边的弹性贴紧到该侧面。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
