其中，基座100包括背板110以及设置于背板110底端的若干安装槽120，背板110上设置有挂钩1101和导向槽1102，安装电表400时，电表400背面的导向条440可沿导向槽1102滑动，对电表400的位移提供导向作用，电表400安装到位时，挂钩1101可钩挂于电表400背面的挂孔420内，对电表400进行定位。
为避免挂钩1101凸起会造成电表400与背板110分离，或挂钩1101误入挂孔420内，影响电表400的安装，本实施例中，该挂钩1101设置于第一弹性板11011上，第一弹性板11011的底端固定于背板110，顶部可沿背板110的前后摆动，第一弹性板11011的顶部固定有挡块11012，安装电表400时，电表400的背面抵接于挡块11012，使第一弹性板11011顶部向后摆动，至挡块11012和挂钩1101后移至低于背板110前表面，使电表400能够与背板110相贴合，避免挂钩1101对电表400的移动造成影响。
值得一提的是，本实施例中，绝缘板300可滑动地安装于背板110上，在未安装电表400的状态下，绝缘板300能够定位于位置A，罩设于柱形接插头 220上方；安装电表400时，绝缘板300能够由电表400带动下移至位置B，使柱形接插头220能够顺利插入电表400的接线孔410内，本实施例中，位置B为绝缘板300与基座100相抵接，无法下移时的位置；在取出电表400时，绝缘板300能够由电表400带动上移，并在电表400被取出时，恢复至位置A的状态。
本实施例中，电表快速更换底座还包括固定于背板110两侧的侧挡板130，该侧挡板130的前端向内倾斜，使电表400能够紧贴背板110，且侧挡板130的前端设置有向内弯折的前挡板131，可避免电表400从基座100上脱落。侧挡板130的固定方式可选用与基座100一体成型，也可选择其他现有的固定连接方式。
图3为本发明提供的电表快速更换底座第一视角的内部拆分结构示意图，图4为本发明提供的电表快速更换底座第二视角的内部拆分结构示意图，参考图3和图4所示，本实施例中，安装槽120的前后两端凸出于背板110的前后两侧，安装槽120前端的顶部开设有避让孔121，安装槽120上还开设有第一进线孔123。本实施例中，安装槽120的底部为开口，第一进线孔123开设于安装槽120的后端，在其他实施例中，安装槽120的开口还可以设置于其他位置，如安装槽120的前端等，第一进线孔123也可以根据需要开设于安装槽120的底端等位置。
接线模块200包括模块本体210以及固定装配于模块本体210的柱形接插头220，其中，模块本体210能够从安装槽120的开口处插入并卡接于安装槽120内，模块本体210上开设有与第一进线孔123位置相对应的第二进线孔215，导线500能够穿过第一进线孔123和第二进线孔215与柱形接插头220电连接；柱形接插头220由导电的金属制成，柱形接插头220的尺寸与电表400的接线孔410尺寸相匹配，柱形接插头220从避让孔121向上伸出，使用时，该柱形接插头220插接于电表400底端所设接线孔410内。
本实施例所提供的电表快速更换底座，接线模块200为模块化的设计，可通过整体组装的方式安装至安装槽120内，能够应用于有着不同柱形接插头220数量的电表快速更换底座的制作；同时，可通过简单的操作实现接线模块200与安装槽120的装配定位，进一步简化电表快速更换底座的安装过程，提高电表快速更换底座的生产效率。
继续参考图3和图4所示，本实施例中，安装槽120和/或背板110上开设 有若干卡孔，模块本体210上设置有若干卡块，模块本体210可通过卡孔与卡块卡接于安装槽120内。
具体的，本实施例中，安装槽120的前端开设有第一卡孔122，背板110上开设有第二卡孔112，模块本体210上设置有第一卡块211和第二卡块212，该第一卡块211卡接于第一卡孔122内，第二卡块212卡接于第二卡孔112内，使模块本体210能够定位于安装槽120内。
当然，本发明不限于此，在其他一些实施例中，也可以在安装槽120和/或背板110的其他位置开设卡孔，并在模块本体210上设置有与卡孔位置相对应的卡块，使模块本体210能够通过卡孔与卡块卡接于安装槽120内，便于模块本体210的快速组装。
进一步的，本实施例中，柱形接插头220由星型槽分隔成四个弹性接插片，弹性接插片的插入端沿周向向外凸起形成凸起部2201。该设计的目的在于，使用时，该凸起部2201能够抵接于电表400的接线孔410侧壁上，以提高柱形接插头220和接线孔410插接的牢固度和紧密性，保证电流传输的通畅。
本实施例所提供的接线模块200除模块本体210外还包括弹片，该弹片整体弯折，其一弯折端从另一弯折端上开设的穿孔内穿过；柱形接插头220的底端固定有金属的连接片，该连接片插接于穿孔内，被夹紧于弯折端和穿孔之间。使用时，导线500能够被夹持于弯折端和连接片之间，与连接片和柱形接插头220电连接。模块本体210内开设有安装腔213，连接片和弹片从安装腔213侧边所设开口插入安装腔213内，形成模块化的接线模块200结构。
具体的，如图5-图7所示，作为一种具体的实施方式，接线模块200除模块本体210外还包括第一弹片230，该第一弹片230整体弯折，其第二弯折端232从第一弯折端231上开设的第一穿孔2311内穿过；柱形接插头220的底端固定有金属的第一连接片221，该第一连接片221插接于第一穿孔2311内，被夹紧于第二弯折端232和第一穿孔2311之间。使用时，导线500能够被夹持于第二弯折端232和第一连接片221之间，与第一连接片221和柱形接插头220电连接。模块本体210内开设有安装腔213，第一连接片221和第一弹片230从安装腔213侧边所设开口插入安装腔213内，形成模块化的接线模块200结构。
作为一优选方案，本实施例中，第一连接片221的自由端设有勾板2211，该勾板2211向下弯折，且勾板2211的宽度小于第一连接片221的宽度，该勾 板2211可卡接于第一穿孔2311的底端，并由第二弯折端232的端部进行压紧，便于组装时对第一连接片221和第一弹片230进行定位。
另外，该接线模块200还包括推块240，且该接线模块200中，第二弯折端232从安装腔213的顶部向下弯折，且与推进孔214的位置相对应，该推块240插接于模块本体210上所开设的推进孔214内，向内推动推块240，能够推动第二弯折端232远离第一连接片221，在第二弯折端232和第一连接片221之间形成间隙，便于对导线500进行插接和抽取。
如图8和图9所示，作为另一种具体的实施方式，接线模块200除模块本体210外还包括第二弹片250，该第二弹片250整体弯折，其第四弯折端252从第三弯折端251上开设的第二穿孔2511内穿过；柱形接插头220的底端固定有金属的第二连接片222，该第二连接片222插接于第二穿孔2511内，被夹紧于第四弯折端252和第二穿孔2511之间。使用时，导线500能够被夹持于弯折端和连接片之间，与第二连接片222和柱形接插头220电连接。模块本体210内开设有安装腔213，第二连接片222和第二弹片250从安装腔213侧边所设开口插入安装腔213内，形成模块化的接线模块200结构。
模块本体210上开设有供条形压片工具伸入的工具孔216，第三弯折端251从安装腔213的顶部向下弯折，且与工具孔216的位置相对应，该压片工具能够推动第三弯折端251下移，使第二穿孔2511的底端远离第二连接片222，便于对导线500进行插接和抽取。
作为一优选方案，本实施例中，第二连接片222的两侧设置有限位凸起2221，使第三弯折端251能够被限位于限位凸起2221与安装腔213侧壁形成的通道内，从而使得第三弯折端251受力时，能够沿着被限定的通道下移，进而保证第二穿孔2511能够与第二连接片222迅速分离。
在另一些实施例中，如图10和图11所示，接线模块200除模块本体210外，还包括压接框260和螺纹件270，其中，压接框260位于模块本体210所开设的竖直滑孔2133内，可沿该竖直滑孔2133上下移动，螺纹件270设置于模块本体210底部所开设的定位孔2135内，螺纹件270旋于压接框260底部所设螺纹孔261内，旋拧螺纹件270能够带动压接框260升降。
具体的，该定位孔2135的顶部设置有卡板2134，定位孔2135内设置向定位孔2135内凸起的卡环21351，由于模块本体210由具有一定弹性的塑料等材质制成，因此，安装螺纹件270时，定位孔2135和卡环21351受挤压变形， 使得螺纹件270的帽端能够进入并卡接于卡环21351以及卡板2134之间，并能够沿其轴向旋转。
柱形接插头220的底端固定有金属的第三连接片223，该第三连接片223插接于压接框260内，导线500能够被夹持于压接框260顶部和连接片之间。插接导线500时，通过旋拧螺纹件270可带动压接框260升降，从而改变压接框260顶部和连接片之间的距离，以便于对导线500进行插接和抽取。
图12为本发明提供的电表快速更换底座的整体拆分结构示意图，参考图12所示，本实施例中，绝缘板300能够扣设于柱形接插头220的顶部和外周，用于对柱形接插头220进行遮挡，防止操作者触碰到柱形接插头220造成触电。
具体的，本实施例中，电表防手指绝缘板还包括设置于绝缘板300两侧的卡件340，其中，绝缘板300由顶板301、前板302和两侧板303围设成簸箕状，顶板301上开设有用于柱形接插头220穿过的接插孔310，该绝缘板300能够沿背板110上下移动。
卡件340位于背板110上所开设的二级限位槽117内，且卡件340不高于背板110的前表面，以避免造成安装时电表400翘起，卡件340上开设有限位孔341；
该卡件340被配置为，当电表400和绝缘板300移动至位置B，电表400背部两凸起的第一装配孔430卡接于限位孔341内，卡件340和绝缘板300能够被凸起的第一装配孔430带动上移；
当卡件340移动至二级限位槽117的顶端，凸起的第一装配孔430能够从限位孔341内脱离，绝缘板300能够悬停于位置A；当绝缘板300悬停于位置A时，顶板301位于柱形接插头220上方，前板302遮挡于柱形接插头220的前侧；
绝缘板300与背板110间设置有卡位结构，绝缘板300能够通过卡位结构悬停于位置A，且绝缘板300能够在电表400插入时从卡位结构上脱离。
本实用新型提供的电表防手指绝缘板，插装电表400时，绝缘板300从卡位结构上落下，柱形接插头220从接插孔310内伸出，插入电表400底端的接线孔410内；取出电表400时，电表400背部两凸起的第一装配孔430带动卡件340和绝缘板300上移，并通过卡位结构定位于柱形接插头220上方。
该电表防手指绝缘板，能够始终对柱形接插头220进行遮挡，且不会影响电表400的安装操作，可降低电表400安装过程中的触电风险，提高电表400 安装的安全性；同时，绝缘板300的移动和定位均能够在电表400插装和取出时自动完成，无需另行进行安装和拆卸，减少电表400拆装时的操作步骤，加快电表400拆装效率。
继续参考图12所示，为限定绝缘板300的移动轨迹，本实施例中，背板110上开设有滑槽114，该滑槽114为截面呈楔形的楔形槽，位于背板110背面的一端外扩，绝缘板300上设置有滑块320，该滑块320与滑槽114的形状相匹配，滑块320插接于滑槽114内，沿滑槽114的长度方向上下滑动，以避免滑块320从背板110的前面脱出。
同时，为避免滑块320从滑槽114的顶端脱出，滑槽114上方的背板110上设置有第二弹性板113，该第二弹性板113由开设于背板110上的U形槽形成，第二弹性板113的顶端固定于背板110，底部可沿背板110的前后摆动，第二弹性板113的底端与滑槽114顶端之间的距离小于滑块320的长度。使用时，可通过压接第二弹性板113使其向背板110后方摆动，进而将滑块320插入滑槽114内，滑块320插入滑槽114后，第二弹性板113恢复至竖直状态，可阻挡滑块320从滑槽114顶部脱离。
本实施例中，卡位结构包括第三弹性板115，该第三弹性板115由开设于背板110上的U形槽形成，第三弹性板115的顶端固定于背板110，底部可沿背板110的前后摆动；第三弹性板115的前表面上设置有弧形凸起1151，第三弹性板115的底端设置有向背板110前方伸出的限位块1152，该限位块1152能够通过卡接阻止绝缘板300下移。
该限位块1152被配置为，当弧形凸起1151与背板110的前平面位于同一平面时，限位块1152后移至不高于背板110的前平面，不会对绝缘板300形成阻挡作用。在应用时，电表400插接时推动弧形凸起1151和第三弹性板115向背板110的后方摆动，限位块1152失去对绝缘板300的卡接作用，绝缘板300下落，使柱形接插头220露出。
当然，本实用新型不限于此，该卡位结构也可以是能够沿背板110的前后伸缩的弹性件，通过在绝缘板300上设置卡槽对弹性件进行卡接，且该弹性件能够在电表400安装时，受到向下的推力从卡槽内脱离。
作为一优选方案，该第三弹性板115的数量为两个，对称设置于背板110的两侧，以保证对绝缘板300定位的平稳性。
图13为本实用新型提供的电表防手指绝缘板的挑件和豁口的位置结构示 意图，参考图13所示，本实施例中，为避免第三弹性板115无法恢复至竖直状态，进而造成限位块1152失去对绝缘板300的卡接作用，该绝缘板300上还设置有挑件330，该挑件330包括向绝缘板300的后上方呈L型弯折的横杆331和竖杆332，竖杆332的顶端设有向背板110的后上方弯折的弯折端333，第三弹性板115的底端开设有向上延伸的豁口1153，挑件330能够伸入豁口1153内并沿豁口1153上下滑动；
该豁口1153的其中一个侧壁为楔形体，该楔形体位于背板110背面的一端向豁口内倾斜，弯折端333上移时，楔形体的底端能够与弯折端333顶面相接并沿弯折端333顶面向前滑动至竖杆332前侧，使第三弹性板115恢复竖直状态，第三弹性板115上的弧形凸起1151凸出于背板110的前表面。
优选的，该弯折端333的自由端呈楔形，以便于安装时，该弯折端333能够顺利进入豁口1153内。
图14为本实用新型提供的电表防手指绝缘板的卡件和一级限位槽的位置结构示意图，参考图14所示，本实施例中，背板110上开设有一级限位槽116，二级限位槽117开设于一级限位槽116的槽底；该设计的目的在于降低电表400背部凸起的第一装配孔430与限位孔341的卡接深度，从而降低第一装配孔430从限位孔341内脱出的难度。
为进一步降低第一装配孔430的脱离难度，本实施例中，二级限位槽117槽底的顶部开设有缓冲槽1171，卡件340的顶部能够向缓冲槽1171内摆动。进一步的，该缓冲槽1171的槽底为倾斜面，以避免卡件340弯折时应力集中于缓冲槽1171的外沿造成卡件340折断。
图15为本实用新型提供的电表防手指绝缘板的卡件结构示意图，参考图14和图15所示，本实施例中，限位孔341的上方结构为第一卡条342，该第一卡条342的表面与二级限位槽117的表面齐平，且该第一卡条342的上下两侧壁均为斜面，以便于电表400的第一装配孔430向下进入限位孔341内以及向上从限位孔341内脱离。
进一步的，限位孔341的下方设置有凸起的第二卡条343，避免第一装配孔430从限位孔341的底端滑脱。优选的，该第二卡条343的表面不高于背板110的前平面，以避免造成电表400安装时底端翘起。
图16为本实用新型提供的电表防手指绝缘板的整体结构示意图，参考图16所示，本实施例中，绝缘板300内设置有筋板350，滑块320固定于支撑杆 370的顶端，挑件330和该支撑杆370均固定于筋板350上，以保证挑件330和滑块320的机械强度。
进一步的，本实施例中，该绝缘板300沿安装槽120外壁上下滑动，为提高绝缘板300与背板110底部结构的尺寸适配度，该绝缘板300的顶板301后侧边沿处开设有若干边槽360，该边槽360可提高绝缘板300顶面的延展性，以使得该绝缘板300能够在一定幅度内与设置于背板110底部的结构外壁紧密贴合，保证其上下滑动时的稳定性。
电表400拆装过程：
初始状态下，绝缘板300被限位块1152卡住，处于位置A，扣设于柱形接插头220的上方。
安装时：电表400下移，电表400的背面接触第三弹性板115的前表面上所设弧形凸起1151，第三弹性板115的底端向背板110的后方摆动，限位块1152同时后移，绝缘板300从限位块1152上脱出后下落，柱形接插头220从绝缘板300顶部的接插孔310内伸出，随电表400下移插入电表400底端所设接线孔410内。
当电表400移动至最低端，即位置B，电表400背部两凸起的第一装配孔430从上端卡条342上滑过，并卡接于两卡条342之间。使用螺纹紧固件穿过第一装配孔430并旋于限位槽116底部所开设的第二装配孔118内。
拆卸时：电表400上移，带动卡件340及绝缘板300上移，当卡件340移动至限位槽116的顶端，电表400与弧形凸起1151相离，第三弹性板115恢复至竖直状态，限位块1152前移，卡接于绝缘板300，绝缘板300恢复至安装前的初始状态，即位置A。此时向前拿出电表400即可。
在另一些实施例中，绝缘板300还可以由弹簧(未图示)实现位置A及位置B的互换，该弹簧设置于绝缘板300与基座100间，示例性的，可设置于绝缘板300下方，也可设置于绝缘板300上方。未安装电表时，绝缘板300受下方压缩状态的弹簧的推力，或受上方拉伸状态的弹簧的拉力作用悬于位置A；安装电表400时,电表400下压绝缘板300，克服弹簧作用力，绝缘板300被下压至位置B，并受电表400重力作用保持位置B的状态；拆卸电表400时，电表400拿开后，绝缘板300受弹簧推力或拉力作用恢复至位置A的状态。
注：文中未经明确说明的固定方式，根据需要可选用螺纹连接、焊接或粘接等常见的固定连接方式。
显然，本发明的上述实施例仅仅是为了清楚说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
