实施例一
如图1-4所示,本申请实施例提供的开关元件,包括:相互扣合的底壳10和面板80,底壳10和面板80之间依次设置有强电板20、隔离板30、弱电板40、垫片50、开关键60和盖板70,开关键60穿过盖板70并伸出面板80;强电板20上设置有强电区和弱电区,隔离板30朝向强电板20的一侧设置有第一隔板32,隔离板30与强电板20接触时,第一隔板32将强电区与弱电区分隔开。
本申请实施例的开关元件中,强电板20和弱电板40之间设置有隔离板30,隔离板30实现了强 电板20和弱电板40之间的隔离,此外,隔离板30上设置有第一隔板32,当将开关元件装配完成后,第一隔板32与强电板20接触,将强电板20上的强电区与弱电区隔离开。
与现有技术中的开关元件相比,由于本申请实施例提供的开关元件中,使用隔离板30将强电板20与弱电板40隔离,且使用隔离板30上的第一隔板32将强电板20上的强电区与弱电区隔离,因此无需通过距离实现强电与弱电的隔离,从而使得开关元件的结构可以更为紧凑,整体尺寸更小。
下面依次说明本实施例提供的开关元件中的各结构:
隔离板30上设置有连接孔34,连接孔34为方形孔,并且连接孔34位于隔离板30的角部上,强电板20与连接孔34相对的区域设置有第一连接器21,弱电板40与连接孔34相对的区域设置有与第一连接器21配合的第二连接器41;隔离板30朝向强电板20的一侧设置有第二隔板33,第二隔板33用于将强电板20的设置有第二连接器41的区域与弱电区隔离。
如图3-6所示,在强电板20上设置有第一连接器21,第一连接器的外轮廓为立方体状,第一连接器21为插接位,插接位上设置有多个插接口,在弱电板40上相应的位置设置有第二连接器41,第二连接器41包括多个插接针。装配时第一连接器21的插接位经由隔离板30的连接口伸出,弱电板40上的插接针插入对应的插接口中,从而实现强电板20与弱电板40的连通。
强电板20远离隔离板30的一侧设置有电路元件,强电板20分为强电区和弱电区;隔离板30靠近强电板20的一侧板面上设置有第一隔板32,第一隔板32从隔离板30上延伸至强电板20,用于分隔强电区和弱电区。
本实施例的可选方案中,隔离板30靠近强电板20的一侧板面上设有凸台36;凸台36的延伸端顶靠强电板20,使隔离板30与强电板20之间留有与凸台36等高的间距。
具体地,凸台36为四个,分别设置在靠近隔离板30四条边的边沿处。凸台36的延伸端能够顶靠强电板20,因此,强电板20与隔离板30之间的距离即为凸台36的高度,凸台36的高度可根据根据强电板20上元器件凸出板面的高度来决定。
进一步地,凸台36上设有沉头孔37,强电板20与沉头孔37对应的位置上设有螺纹孔,隔离板30与强电板20通过螺钉连接。
为实现隔离板30与强电板20之间的连接,减少隔离板30的厚度,在凸台36上设置沉头孔37。如若将沉头孔37设置在隔离板30的板面上,根据沉头孔37和螺钉的国标要求,隔离板30必然具有一定的厚度,过厚的隔离板30不仅增加了整个开关元件的重量,还增大了整理的体积。因此,将沉头孔37设置在已经具备一定高度的凸台36上,即实现了隔离板30与强电板20之间的连接,又大大地节约了空间。
强电板20背离隔离板30的一侧安装有电路元件,在该侧的还设置有多个接线柱组件,多个接线柱22沿强电板20的宽度方向间隔设置,各个接线柱组件均与强电板20螺纹连接。
作为一种实施方式,接线柱组件包括接线柱22、固定螺栓23和压接螺栓24,固定螺栓23用于将接线柱22固定到强电板20上,压接螺栓24用于将外接的导线与接线柱22压到一起,使得导线与接线柱22连通。
具体地,导线进入孔27设置在接线柱22顶部;压接孔28设置在接线柱22外侧壁上,且压接孔28的轴线与导线进入孔27的轴线垂直;压接螺栓24与压接孔28螺纹连接。外部导线插入到导线进入孔27中,并进入到压接孔28的底部位置,压接螺栓24与压接孔28螺纹连接,拧动压接螺栓24直至与外部导线接触并压紧。具体地,导线进入孔27为圆孔,外部导线压接后与导线进入孔27内壁的接触面相比与平面接触的面积,接触面积更大,导电效果更好。同理,在压接螺栓24的端部设置一个接触挡片,该接触挡片呈圆弧状,其弯曲半径与外部导线的半径相等,压接螺栓24通过该接触挡片与外部导线压紧,进一步增加了与导线的接触面积,因此进一步提高了导电性能,从而提高整体的可靠性。
具体地,强电板20上设置有多个通孔25,通孔25为圆形通孔,接线柱22位于强电板20的一侧,接线柱22的底部设有内螺纹,固定螺栓23从强电板20的另一侧穿过通孔25以与接线柱22的底部的内螺纹螺纹连接,以将接线柱22固定在强电板20上。
接线柱22、强电板20和固定螺栓23顺序设置;接线柱22方形柱体,方形柱体的其中一个端部设置了内螺纹,固定螺栓23由强电板20的底部穿过通孔25,与内螺纹进行螺纹连接,从而将接线柱22固定在强电板20上。相比传统将接线柱22直接焊接在强电板20上的方式进行连接,本申请实施例将接线柱22通过固定螺栓23进行连接的方式使接线柱22更不易从强电板20上松脱,且拆 装更加方便。外部接入的导线通过固定螺栓23进行导电。基于此,本申请实施例较之原有技术,具有连接牢固、可靠性高的优点。
一般将接线柱22直接焊接在强电板20上的方式,强电板20上焊接部位必然向外凸出一定的厚度,接线柱22上的引脚过长,则焊接部位向外凸的厚度大;接线柱22上的引脚过端,则不便于焊接,容易焊不严实,从而造成导电的可靠性降低。本实施例对接线柱22的连接方式进行改进,将原本焊接方式改为利用固定螺栓23的方式将接线柱22固定在强电板20上,该固定螺栓23优选为平头螺栓。
作为另一种实施方式,接线柱组件,包括接线柱22、强电板20、固定螺栓23、压接螺栓24和限位挡板;接线柱22的底部设有内螺纹,强电板20上设置有通孔25,固定螺栓23穿过通孔25与内螺纹配合,以将接线柱22固定在强电板20上;接线柱22的一个端面设有导线进入孔27,接线柱22外侧壁上设置有压接孔28,压接孔28与导线进入孔27连通;压接螺栓24与压接孔28螺纹连接;限位挡板设置在压接螺栓24的外部,且限位挡板上与压接螺栓24相对应的位置上设置有第一通孔,第一通孔的直径小于压接螺栓24的螺钉头直径。
传统的接线过程,压接螺栓24从底壳10外部拧入,当需要拧松压接螺栓24进行调整时,若把握不好,容易使压接螺栓24脱出,给安装和维修造成很大的不便。本实施例在压接螺栓24的外部设置挡板,该挡板上与压接螺栓24对应的位置设置了第一通孔,该第一通孔的直径小于压接螺栓24的螺钉头直径,螺钉头到挡板的距离能够需能够防止螺钉脱扣掉出。
接线柱22远离导线进入孔27的端面设有内螺纹,强电板20上设置有通孔25,固定螺栓23穿过通孔25与内螺纹配合,以将接线柱22固定在强电板20上。
接线柱22、强电板20和固定螺栓23顺序设置;接线柱22方形柱体,方形柱体的其中一个端部设置了内螺纹,固定螺栓23由强电板20的底部穿过通孔25,与内螺纹进行螺纹连接,从而将接线柱22固定在强电板20上。相比传统将接线柱22直接焊接在强电板20上的方式进行连接,本申请实施例将接线柱22通过固定螺栓23进行连接的方式使接线柱22更不易从强电板20上松脱,且拆装更加方便。外部接入的导线通过固定螺栓23进行导电。本申请实施例较之原有技术,具有连接牢固、可靠性高、不易脱扣的优点。
相对地,隔离板30朝向强电板20的一面上设置有多个螺栓容纳槽35,多个螺栓容纳槽35沿隔离板30的宽度方向间隔设置,并且多个螺栓容纳槽35与多个固定螺栓23一一对应设置,以用于容纳固定螺栓23的头部。为了达到更好的隔离效果,第一隔板32同时用于隔离强电板20上各个接线柱组件的安装区域,举例来说,第一隔板32包括横板和纵板,横板和纵板围成多个接线柱隔离区,每个接线柱隔离区内对应设置有一个螺栓容纳槽35。各接线柱22所在区域均为强电区,因此,第一隔板32在将强电板20上的强电区与弱电区隔离开的同时,也将各接线柱22对应的区域隔离开,从而提高隔离效果。
为进一步缩短强电板20与隔离板30之间的距离,可在隔离板30上靠近强电板20的一侧表面设置用于容纳固定螺栓23的螺钉头的螺栓容纳槽35。没有设置螺栓容纳槽35前,强电板20与隔离板30之间的空间必须保证能够容纳螺钉头的厚度,因此,本实施例通过在隔离板30上设置用于容纳固定螺栓23的螺钉头的螺栓容纳槽35,以进一步减少强电板20与隔离板30之间的距离,从而进一步提高了开关元件的整体紧凑性。
本实施例的可选方案中,隔离板30相对的两条边上对称设置有弧形槽38。弧形槽38方便操作者抓取隔离板30。同理强电板20和弱电板40相对的两条边上也可对称设置弧形槽38。
本实施例的可选方案中,隔离板30靠近弱电板40的一侧板面镀有一层隔离膜。为进一步提高隔离板30隔离强弱电的效果,在隔离板30靠近弱电板40的一侧镀上一层隔离膜。
底壳10朝向强电板20的一侧设置有多个接线柱容纳腔11,容纳腔11包括横板和纵板,横板、纵板和底壳10的内侧壁围成多个接线柱容纳腔11,每个接线柱组件对应位于一个接线柱容纳腔11中,底壳10上每个接线柱容纳腔11内均设置有接线孔12和固定孔13。如此设计,接线孔12用于容纳固定螺栓23的头部,固定孔13用于容纳压接螺栓24的头部,各接线柱组件均位于各自对应的接线柱容纳腔11中,接线柱容纳腔11将多个接线柱组件一一隔离,从而实现各接线柱22之间良好地隔绝作用,且对各接线柱组件起到限位作用。此外,底壳10上还设置有散热口14,散热口14设置在底壳10的侧壁上,散热口14为矩形散热口,并且散热口14为多个,多个散热口14间隔设置。
接线柱22与压接螺栓24螺纹连接,压接螺栓24的头部朝向固定孔13设置,固定孔13为圆形 通孔,固定孔13设置在底壳10的内侧壁上,固定孔13的直径小于压接螺栓24的头部的最大直径,从而防止压接螺栓24从固定孔13中掉出。
接线孔12为圆形盲孔,接线孔12设置在底壳10的朝向强电板20的一面上,接线柱22与固定螺栓24螺纹连接,固定螺栓23的头部朝向接线孔12设置,接线孔12用于容纳固定螺栓23的头部。
本实施例的可选方案中,压接螺栓24的螺杆上设置有两段螺纹,两段螺纹之间为光滑区。两段螺纹的设置能够进一步防止脱扣。具体的,在接线柱22上的螺纹孔内的螺纹仅有一段,压接螺栓24拧入后,压接螺栓24上靠近头部的一段螺纹与螺纹孔内的螺纹连接,另一段螺纹不与螺纹孔内的螺纹连接;拧松压接螺栓24时,若靠近头部的一段螺纹脱出,由于两段螺纹之间设置了光滑区,操作者容易判断此时压接螺栓24已经到了一定位置,该位置能够使外部导线插入,又因第二段螺纹的存在,压接螺栓24无法从螺纹孔内脱出,方便了安装和维修。
进一步的,所述两段螺纹的旋向相反。若两段螺纹的旋向相同,操作者在第一段螺纹脱出时没有及时察觉出螺纹已脱扣而继续朝着原来的方向拧动压接螺栓24,最终还可能导致压接螺栓24完全脱扣。因此,本实施例将两段螺纹的旋向设置为相反的旋向,在第一段螺纹脱出时,若继续朝一个方向拧动压接螺栓24,则压接螺栓24无法脱出。
在接线柱22上设置有引脚221,引脚221为多个并设置在接线柱22朝向强电板20的一面上,每个引脚221的外轮廓为立方体状,且引脚221的边缘处设有圆角强电板20上设置有引脚孔26,引脚孔26为矩形孔,且矩形孔的角部设有圆角,在装配过程中,先将引脚221插到引脚孔26中,然后再使用固定螺栓23将接线柱22和强电板20固定在一起,每个固定螺栓23的两侧分别设有两个引脚221,引脚221与引脚孔26的配合,在装配过程中起到定位作用,在装配完成后,引脚孔26对引脚221起到限位作用,从而对接线柱22起到限位作用。
为了进一步提高接线柱22与强电板20的连接可靠性,可以将引脚221直接焊接在强电板20上,万一固定螺栓23松脱,由于引脚221与强电板20直接焊接,接线柱22也不会轻易从强电板20上脱落,因此保证了接入其中的导线在工作过程中始终处于导通状态。
进一步的,每个接线柱22上的引脚221为两个;两个引脚221关于接线柱22的轴线对称设置;每个接线柱22上的引脚孔26为两个;两个引脚孔26关于通孔25的圆心对称设置。引脚孔26靠近接线柱22的一端为上端,远离接线柱22的一端为下端,本实施例中,引脚孔26的下端开口小于上端开口,具体的,引脚孔26的上端开口大于引脚221的横截面积,引脚孔26的小端开口等于或略小于引脚221的横截面积。引脚221从上端开口穿入,从小端开口穿出时,由于下端开口等于或略小于引脚221的横截面积,引脚221被仅仅的卡接在小端开口处,使得引脚221在焊接过程中不轻易松脱。
实际应用时,为了对开关元件的内部电路板进行良好地密封,如图7所示,本申请实施例提供的开关元件中,底壳10朝向盖板70的一侧设有容纳台,且容纳台设有多条第一支撑筋15;盖板70位于面板80与底壳10之间、且放置在容纳台处,盖板70与容纳台接触的一面设有与多条第一支撑筋15匹配对应的第二支撑筋。上述第一支撑筋15和第二支撑筋的设置,也有利于热量的扩散,起到良好地散热效果。
其中,为了便于开启盖板70,盖板70的边沿可以设有凹槽76,从而通过该凹槽76可以便捷地将盖板70翘起,也即实现盖板70的开启。
具体地,盖板70的上边沿和下边沿可以分别设有一个凹槽76,盖板70的左边沿和右边沿可以分别设有两个对称分布的凹槽76。此种设置,便于从各个方向通过凹槽76将将盖板70翘起。当然,上述凹槽76的具体数量和分布位置,在此不做限制,也可以为其它合理形式。
在弱电板40上设置有接触片,垫片50位于接触片上方,垫片50上设置有限位块51,限位块51为多个,多个限位块51沿垫片50的长度方向间隔设置,并且限位块由底座和凸块组成,底座为立方体状底座,凸块固定在底座上,且凸块为十字形凸块,垫片50与限位块51为一体结构,由柔性材质一体成型制成。开关键60扣合于限位块51上。
盖板70与垫片50的边缘相对的区域设置有环形凸台71,环形凸台71上设置有限位凸起72,限位凸起72为多个,多个限位凸起72沿环形凸台71的周向间隔设置,垫片50上设置有与限位凸起72配合的限位孔52。在装配完成后,环形凸台71压在垫片50上,限位凸起72插入限位孔52中,从而使得盖板70与垫片50之间的密封性更好。
盖板70上设置有供开关键60通过的第一开关过孔73,面板80上设置有供开关键60通过的第 二开关过孔81,在盖板70背离垫片50的一侧位于第一开关过孔73周围的区域设置有环形槽74,对应地,在面板80朝向盖板70的一侧位于第二开关过孔81的周围的区域设置有环形凸块82。在开关元件装配完成后,环形凸块82抵在环形槽74中,从而增强了盖板70与面板80之间的密封性,防止灰尘经由开关键60与面板80之间的缝隙进入开关元件中设置有强电板20或弱电板40的区域。

实际应用时,为了有效提高面板80的强度,本申请实施例提供的开关元件中,上述面板80的四周可以分别设有加强筋,从而通过该加强筋起到良好地加固作用,进而有效提高面板80的强度。
其中,为了保证加强筋85的加强效果,本申请实施例提供的开关元件中,上述面板80的每侧边沿均可以分别设有三个加强筋85,且三个加强筋85均匀分布。当然,上述加强筋85的具体数量和分布位置,在此不做限制,也可以为其它合理形式。

本申请实施例的开关系统的开关元件中,强电板和弱电板之间设置有隔离板,隔离板实现了强电板和弱电板之间的隔离,此外,隔离板上设置有第一隔板,当将开关元件装配完成后,第一隔板与强电板接触,将强电板上的强电区与弱电区隔离开。
与现有技术中的开关系统相比,由于本申请实施例提供的开关系统的开关元件中,使用隔离板将强电板与弱电板隔离,且使用隔离板上的第一隔板将强电板上的强电区与弱电区隔离,因此无需通过距离实现强电与弱电的隔离,从而使得开关元件的结构可以更为紧凑,整体尺寸更小。
实施例三
本申请实施例提供了PCB隔离板组件,包括了实施例一中所述的强电板20、隔离板30和弱电板40,实施例二所描述的技术方案也属于该实施例。本实施例,包括顺序设置的强电板20、隔离板30和弱电板40;强电板20靠近隔离板30的一侧板面设置有第一连接器21,隔离板30上与第一连接器21对应的位置设置有连接孔34,弱电板40靠近隔离板30的一侧板面设置有与第一连接器21配合的第二连接器41。
本申请实施例的PCB隔离板组件,强电板20和弱电板40之间设置有隔离板30,隔离板30实现了强电板20和弱电板40之间的隔离,此外,隔离板30上设置有第一隔板32,当将开关元件装配完成后,第一隔板32与强电板20接触,将强电板20上的强电区与弱电区隔离开。
与现有技术中的PCB隔离板组件相比,由于本申请实施例提供的PCB隔离板组件中,使用隔离板30将强电板20与弱电板40隔离,且使用隔离板30上的第一隔板32将强电板20上的强电区与弱电区隔离,因此无需通过距离实现强电与弱电的隔离,从而使得PCB隔离板组件的结构可以更为紧凑,整体尺寸更小。
下面依次说明本实施例提供的PCB隔离板组件中的各结构:
隔离板30上设置有连接孔34,连接孔34为方形孔,并且连接孔34位于隔离板30的角部上,强电板20与连接孔34相对的区域设置有第一连接器21,弱电板40与连接孔34相对的区域设置有与第一连接器21配合的第二连接器41;隔离板30朝向强电板20的一侧设置有第二隔板33,第二隔板33用于将强电板20的设置有第二连接器41的区域与弱电区隔离。
如图3-6所示,在强电板20上设置有第一连接器21,第一连接器的外轮廓为立方体状,第一连接器21为插接位,插接位上设置有多个插接口,在弱电板40上相应的位置设置有第二连接器41,第二连接器41包括多个插接针。装配时第一连接器21的插接位经由隔离板30的连接口伸出,弱电板40上的插接针插入对应的插接口中,从而实现强电板20与弱电板40的连通。
强电板20远离隔离板30的一侧设置有电路元件,强电板20分为强电区和弱电区;隔离板30靠近强电板20的一侧板面上设置有第一隔板32,第一隔板32从隔离板30上延伸至强电板20,用于分隔强电区和弱电区。
本实施例的可选方案中,隔离板30靠近强电板20的一侧板面上设有凸台36;凸台36的延伸端顶靠强电板20,使隔离板30与强电板20之间留有与凸台36等高的间距。
具体地,凸台36为四个,分别设置在靠近隔离板30四条边的边沿处。凸台36的延伸端能够顶靠强电板20,因此,强电板20与隔离板30之间的距离即为凸台36的高度,凸台36的高度可根据根据强电板20上元器件凸出板面的高度来决定。
进一步地,凸台36上设有沉头孔37,强电板20与沉头孔37对应的位置上设有螺纹孔,隔离板30与强电板20通过螺钉连接。
为实现隔离板30与强电板20之间的连接,减少隔离板30的厚度,在凸台36上设置沉头孔37。如若将沉头孔37设置在隔离板30的板面上,根据沉头孔37和螺钉的国标要求,隔离板30必然具有一定的厚度,过厚的隔离板30不仅增加了整个开关元件的重量,还增大了整理的体积。因此,将沉头孔37设置在已经具备一定高度的凸台36上,即实现了隔离板30与强电板20之间的连接,又 大大地节约了空间。

具体地,底壳10与面板80卡接扣合后,卡爪16处于缺口83内,且卡爪16与缺口83之间留有缝隙。由此分析可知,使用本申请实施例提供的开关元件时,当需要将扣合的面板80与底壳10再次分离时,可以通过螺丝刀等工具(例如一字改锥)插入卡爪16与缺口83之间的缝隙中,方便地将面板80与底壳10撬开并分离,从而在不破坏开关壳体的情况下,实现开关壳体地轻松拆卸,不仅使用方便,而且能够有效延长开关壳体的使用寿命。
其中,本申请实施例提供的开关壳体中,上述卡爪16可以位于底壳10的底侧边沿,且对称分布有两个;相应地,上述缺口83可以位于面板80的底侧边沿,且对称分布有两个。此种设置,比单独只设置有一个卡爪16和一个缺口83,对开关壳体的保护作用更好,受力更均匀。
当然,卡爪16可以为一个,也可以为多个,缺口83可以为一个也可以为多个,上述卡爪16和缺口83的具体数量和分布位置,在此不做限制,也可以为其它合理形式。
实际应用时,为了较好地实现面板80与底壳10之间的扣合,上述面板80的边沿可以设有凸起84,相应地,上述底壳10的边沿可以对应该凸起84处设有卡槽17,从而实际装配时,能够通过凸起84与卡槽17的卡接配合,以实现面板80与底壳10之间的卡接扣合。
其中,为了保证面板80与底壳10扣合后的稳定性,上述凸起84可以位于面板80的顶侧边沿和底侧边沿,且每侧边沿可以分别对称分布有两个,上述卡槽17可以位于底壳10的顶侧边沿和底侧边沿,且每侧边沿可以分别对称分布有两个。当然,上述凸起84和卡槽17的具体数量和分布位置,在此不做限制,也可以为其它合理形式。
具体地,为了便于将面板80与底壳10撬开并分离,上述两个凸起84可以优选为位于两个缺口83之间,相应地,上述两个卡槽17可以优选为位于两个卡爪16之间。

实施例七
本申请实施例提供一种接线柱组件,包括实施例一中所述的接线柱22、压接螺栓24和限位挡板;实施例一所描述的技术方案也属于该实施例。
本实施例提供的接线柱组件,包括接线柱22、强电板20、固定螺栓23、压接螺栓24和限位挡板;接线柱22的底部设有内螺纹,强电板20上设置有通孔25,固定螺栓23穿过通孔25与内螺纹配合,以将接线柱22固定在强电板20上;接线柱22的一个端面设有导线进入孔27,接线柱22外侧壁上设置有压接孔28,压接孔28与导线进入孔27连通;压接螺栓24与压接孔28螺纹连接;限位挡板设置在压接螺栓24的外部,且限位挡板上与压接螺栓24相对应的位置上设置有第一通孔,第一通孔的直径小于压接螺栓24的螺钉头直径。
传统的接线过程,压接螺栓24从底壳10外部拧入,当需要拧松压接螺栓24进行调整时,若把握不好,容易使压接螺栓24脱出,给安装和维修造成很大的不便。本实施例在压接螺栓24的外部设置挡板,该挡板上与压接螺栓24对应的位置设置了第一通孔,该第一通孔的直径小于压接螺栓 24的螺钉头直径,螺钉头到挡板的距离能够需能够防止螺钉脱扣掉出。
接线柱22远离导线进入孔27的端面设有内螺纹,强电板20上设置有通孔25,固定螺栓23穿过通孔25与内螺纹配合,以将接线柱22固定在强电板20上。
接线柱22、强电板20和固定螺栓23顺序设置;接线柱22方形柱体,方形柱体的其中一个端部设置了内螺纹,固定螺栓23由强电板20的底部穿过通孔25,与内螺纹进行螺纹连接,从而将接线柱22固定在强电板20上。相比传统将接线柱22直接焊接在强电板20上的方式进行连接,本申请实施例将接线柱22通过固定螺栓23进行连接的方式使接线柱22更不易从强电板20上松脱,且拆装更加方便。外部接入的导线通过固定螺栓23进行导电。本申请实施例较之原有技术,具有连接牢固、可靠性高、不易脱扣的优点。
实施例八
本申请实施例提供一种接线柱组件,包括实施例一中所述的接线柱22、固定螺栓23和压接螺栓24;实施例一所描述的技术方案也属于该实施例。
本实施例提供的接线柱组件,包括接线柱22、固定螺栓23和压接螺栓24,固定螺栓23用于将接线柱22固定到强电板20上,压接螺栓24用于将外接的导线与接线柱22压到一起,使得导线与接线柱22连通。
具体地,导线进入孔27设置在接线柱22顶部;压接孔28设置在接线柱22外侧壁上,且压接孔28的轴线与导线进入孔27的轴线垂直;压接螺栓24与压接孔28螺纹连接。外部导线插入到导线进入孔27中,并进入到压接孔28的底部位置,压接螺栓24与压接孔28螺纹连接,拧动压接螺栓24直至与外部导线接触并压紧。具体地,导线进入孔27为圆孔,外部导线压接后与导线进入孔27内壁的接触面相比与平面接触的面积,接触面积更大,导电效果更好。同理,在压接螺栓24的端部设置一个接触挡片,该接触挡片呈圆弧状,其弯曲半径与外部导线的半径相等,压接螺栓24通过该接触挡片与外部导线压紧,进一步增加了与导线的接触面积,因此进一步提高了导电性能,从而提高整体的可靠性。

接线柱22、强电板20和固定螺栓23顺序设置;接线柱22方形柱体,方形柱体的其中一个端部设置了内螺纹,固定螺栓23由强电板20的底部穿过通孔25,与内螺纹进行螺纹连接,从而将接线柱22固定在强电板20上。相比传统将接线柱22直接焊接在强电板20上的方式进行连接,本申请实施例将接线柱22通过固定螺栓23进行连接的方式使接线柱22更不易从强电板20上松脱,且拆装更加方便。外部接入的导线通过固定螺栓23进行导电。基于此,本申请实施例较之原有技术,具有连接牢固、可靠性高的优点。
一般将接线柱22直接焊接在强电板20上的方式,强电板20上焊接部位必然向外凸出一定的厚度,接线柱22上的引脚过长,则焊接部位向外凸的厚度大;接线柱22上的引脚过端,则不便于焊接,容易焊不严实,从而造成导电的可靠性降低。本实施例对接线柱22的连接方式进行改进,将原本焊接方式改为利用固定螺栓23的方式将接线柱22固定在强电板20上,该固定螺栓23优选为平头螺栓。

实施例十一
图14为本申请实施例提供的智能设备控制装置结构示意图。
参照图14,智能设备控制装置包括:按键1、微处理模块2和双稳态触发芯片4;双稳态触发芯片4配置成将触发按键1生成的脉冲信号转化为第一控制信号,并翻转继电器开关状态值,将当前状态值发送至微处理模块2,并按照第一控制信号控制继电器开关动作;微处理模块2配置成将当前状态值与历史状态值进行比对,判断当前状态值是否发生翻转,在当前状态值未发生翻转的情况 下,将脉冲信号进行处理得到第二控制信号,翻转历史状态值,并按照第二控制信号控制继电器开关动作。
具体地,本申请实施例提供的智能设备控制装置采用双通道控制方式,可以避免微处理模块2或双稳态触发芯片4单个部件无法使用时,不能控制继电器开关,进而不能控制智能设备工作;这里,并不局限于双稳态触发芯片4,通过一个脉冲信号能够产生高低电平信号的各种芯片和实现电路均可替代双稳态触发芯片4,均属此方案的替代方案;其中,双稳态触发芯片4通过内部触发结构将脉冲信号转化为第一控制信号;
进一步的,按键1配置成生成脉冲信号,并将脉冲信号分别发送至双稳态触发芯片4和微处理模块2。具体地,按键1触发生成的脉冲信号,同时发送给双稳态触发芯片4和微处理模块2;进一步的,微处理模块2还配置成在当前状态值发生翻转的情况下,翻转历史状态值。进一步的,还包括选择器3,配置成接收第一控制信号和第二控制信号,并按照预设优先级选择第一控制信号或第二控制信号控制继电器开关动作。进一步的,选择器3为单片机。具体地,根据选择器3内部预设的优先级,对第一控制信号或第二控制信号进优先选择,并通过被选控制信号控制继电器开关动作,进而控制智能设备;进一步的,第一控制信号和第二控制信号为电平控制信号。这里,微处理模块2通过预设的内部程序将脉冲信号转化为高低电平控制信号;进一步的,微处理模块2还配置成在当前状态值未发生翻转的情况下,将故障信号发送至上位机。此时,双稳态触发芯片4处于故障情况,由微处理模块2控制继电器开关动作,并将双稳态触发芯片4的故障情况,以故障信号的形式发送至上位机,以使工作人员及时对双稳态触发芯片4进行检测修复,保证对智能设备的控制可靠性;具体地,微处理模块2采用Zigbee(紫蜂)无线通讯协议,进行信号传输;其中,Zigbee是基于IEEE802.15.4标准的低功耗局域网协议。根据国际标准规定,Zigbee技术是一种短距离、低功耗的无线通信技术。
进一步的,如图16所示,智能设备包括继电器开关。这里,继电器开关和智能设备主体相连接;具体地,智能设备控制装置配置成控制应用继电器开关的智能设备,此类智能设备种类繁多,被广泛应用,因此,含有继电器开关的智能设备的控制尤为重要;其中,应用继电器开关的智能设备包括各类智能插座,如实施例一中的插座;进一步的,微处理模块2和双稳态触发芯片4相互独立地控制继电器开关动作。
具体地,当微处理模块2失效或内部程序跑飞时,双稳态触发芯片4仍能独立工作,产生第一控制信号,控制继电器开关开断进行工作;当双稳态触发芯片4失效时,微处理模块2根据状态值的翻转状态检测到双稳态触发芯片4失效,此时。微处理模块2自动产生第二控制信号,控制继电器开关开断进行工作。只有在微处理模块2和双稳态触发芯片4同时失效的情况下,按键1才不能正确的控制继电器开关工作。
因此,采用此种智能设备控制方式极大的提高了智能设备应用的可靠性。这里,微处理模块2是否存在,并不影响按键1通过双稳态触发芯片4使智能设备正常工作。图15为本申请实施例提供的智能设备控制装置电路结构示意图。
参照图15,按键按一下产生一个脉冲信号,双稳态触发芯片检测到脉冲信号时,从Q端输出第一控制信号,选择器通过预设优先级,优先选择第一控制信号,控制继电器开关工作,同时,双稳态触发芯片~Q输出端发送当前状态值(即继电器开关处于工作状态)给微处理模块,微处理模块与上一时刻继电器开关进行比对,判别出当前状态值发生了翻转,并存储继电器开关的当前状态值。
这里,按键触发的脉冲信号,双稳态触发芯片和微处理模块同时接收到,微处理模块接收到按键的脉冲信号,判断从~Q端接收的当前状态值的是否发生翻转,如果发生了翻转,微处理模块记录当前状态值;若从~Q端接收的当前状态值没有发生翻转,则双稳态触发芯片失效,微处理模块产出第二控制信号给选择器,选择器选择第二控制信号控制继电器开关,微处理模块记录继电器开关的当前状态值,并且微处理模块将双稳态触发芯片的故障报告给上位机。
本申请实施例提供了智能设备控制装置和系统,包括按键、微处理模块和双稳态触发芯片;双稳态触发芯片,配置成将触发按键生成的脉冲信号转化为第一控制信号,并翻转继电器开关状态值,将当前状态值发送至微处理模块,并按照第一控制信号控制继电器开关动作;微处理模块,配置成将当前状态值与历史状态值进行比对,判断当前状态值是否发生翻转,在当前状态值未发生翻转的情况下,将脉冲信号进行处理得到第二控制信号,翻转历史状态值,并按照第二控制信号控制继电器开关动作,通过双通道控制智能设备,提高智能设备控制方式的可靠性。

如图20所示,恒流稳压电源系统600包括恒流稳压电源、二极管D1和电容C2,其中,恒流稳压电源系统600包括稳压管ZW、三极管Q1和电容C1;三极管Q1的集电极分别与稳压管ZW的阴极、电容C1的一端、二极管D1的阳极和继电器系统500的继电器J3相连接,三极管Q1的基极与稳压管ZW的阳极相连接,三极管Q1的发射极分别与电容C1的另一端和电容C2的一端相连接并接地,二极管D1的阴极分别与电容C2的另一端以及继电器系统500、AC-DC变换器200和DC-DC变换器300之间的交点相连接。这里,稳压管ZW的电压可以为5.1V,恒流稳压电源可以为5.7V恒流稳压电源。
如图21所示,继电器系统500包括继电器J3和三极管Q2;继电器J1的第一端分别与高压微电源100的整流桥BR和AC-DC变换器200相连接,继电器J1的第二端分别与恒流稳压电源系统600中稳压管ZW的阴极、三极管Q1的集电极、电容C1的一端和二极管D1的阳极相连接,继电器J1的第三端分别与AC-DC变换器200和DC-DC变换器300相连接,继电器J1的第四端与三极管Q2的集电极相连接,三极管Q2的基极与控制系统400相连接,三极管Q2的发射极接地。

单火线取电电路的工作原理为:
将恒流稳压电源与继电器J3串联。当控制系统400使三极管Q2导通,继电器J3线圈通电,继电器J3闭合,此时,恒流稳压电源输出5.7V的电压,并通过二极管D1向控制系统400提供5V的电压供电;
当继电器J3断开时,继电器J3两端形成压差自动切换为高压微电源100供电,即,在负载R没有接通时,负载R的漏电阻提供漏电流,推动AC-DC变换器200输出5V的电压,再通过DC-DC变换器300变换输出3.3V的电压,维持控制系统400工作。
本实施例提供的单火线取电电路在继电器J3导通后,通过恒流稳压电源利用市电的一部分电压来维持控制系统400供电,不需要短暂断开继电器J3来取电,负载R可以一直保持通电,使负载R稳定工作。而且电路结构非常简单,能够节约功耗,提高可靠性。

进一步的,在负载R断开的情况下,控制系统生成断开控制信号,并根据断开控制信号控制三极管Q2断开,继电器J3断电并断开,在继电器J3断开的情况下,负载R的漏电阻向整流桥BR输出漏电流,整流桥BR对漏电流进行整流后输出直流电信号,并将直流电信号传输至AC-DC变换器,AC-DC变换器将直流电信号进行转换后输出5V的第一电压信号,并将5V的第一电压信号传输至DC-DC变换器,DC-DC变换器将5V的第一电压信号进行转换后输出3.3V的第二电压信号,并将3.3V的第二电压信号传输至控制系统。
