Description

旋转式电连接装置及插头、 插座、 插线板 技术领域
本发明涉及电连接装置, 具体涉及一种旋转式电连接装置, 以及插头、 插座、 插线板。 背景技术
一直以来,较为传统的电连接方式以及电连接装置均是采用 直插式连接, 这种传统的连接方式实现和使用均非常简便, 其结 构是通过电极的金属触点自身的弹性和导电性来完成电连接, 用 户通过手持插头垂直插入插座的电极插孔中, 使得插头的金属触 点接触到插座的金属触点, 并被插座的金属触点所夹紧, 以此完 成电连接。
当用户需要断开电连接时, 需要手持插头将插头的金属触点 从电极孔中垂直拔出, 此时插头的金属触点会克服插座的金属触 点的夹紧力, 从插座的金属触点脱离连接。 由于电极孔通常要略 宽于插头电极的厚度, 这样使得用户在插入时如果插入角度不是 垂直于插座, 则可能造成不同的电极完成电连接的时刻不同, 从 而形成电极间拉弧的情况, 而高温的电弧还可能造成电连接装置 的部件失效或熔化, 从而造成火灾的隐患。 发明内容
传统的直插式电连接方式虽然存在一定的安全隐患,但由于 应用的场合通常是小功率电器的电源供应, 因此为人们广泛使用 了很多年。 发明人注意到随着日益增多的大功率电器 (例如空调 等) 进入到人们的办公场所和家庭, 目前大功率电器如果继续釆 用现有的直插式电连接方式, 该方式的安全隐患以及电连接的可 靠性等将可能带来严重的后果。
基于发明人发现的上述技术问题,本发明的一个目的是提出 一种旋转式电连接装置及其插头、 插座、 插线板, 能够改善直插 式电连接方式的电连接可靠性问题, 并尽量消除安全隐患。
为实现上述目的,本发明一个方面提供了一种旋转式电连接 装置, 包括:
插头, 具有插头本体, 在插头的底面设有至少两个第一金属 插座, 具有底座, 在底座内部设有至少两个第二金属触点, 所述底座还设有引导所述第一金属触点从插入位置旋至所述第二 金属触点完成电连接的旋转引导机构。
上述技术方案相比于传统的直插式电连接装置, 由于采用了 先无电插入, 再旋转接通的电连接方式, 基于旋转引导机构可以 使金属触点能够更稳定的接触, 并且尽量排除了由于用户的操作 可能造成的不同的电极完成电连接的时刻不同而产生的电弧, 在 确保了一定的制造精度的情况下, 借助旋转引导机构进行旋转接 电可以尽量保证电极同时完成电连接, 从而尽可能的减少和消除 电弧的产生, 消除火灾隐患, 并且对于小功率或者大功率的电器 均可以适用。

优选的,在所述插座的底座内还设有覆盖在所述第二金属触 点之上的绝缘盖, 通过所述绝缘盖和绝缘隔板将各个第二金属触 点之间分割为封闭的独立电极仓。 通过绝缘隔板和绝缘盖可以增 加各第二金属触点之间的爬电距离和电气间隙, 使其达到安全距 离, 避免电极之间瞬间放电引起的短路, 提高电连接装置的安全 系数, 而且在接通和断开电连接时, 即使产生了电弧, 也会被挡 在绝缘盖内, 无法跃出插入孔, 从而消除了用户触电的危险。
优选的, 所述插座的底座内还设有防护门组件, 所述防护门 组件包括相对于所述底座可转动的动片, 所述动片具有垂直贯通 的容纳部分, 所述容纳部分内设有遮挡部分, 在非工作状态下, 所述动片的容纳部分被所述遮挡部分所遮挡, 在工作状态, 所述 动片的容纳部分不被所述遮挡部分所遮挡。
通过防护门组件可以使旋转式电连接装置在非工作状态时, 用户无法直接触碰到电连接插座内的金属触点, 即使用户用细长 的导电物体穿过动片的遮挡部分, 由于其插入位置距离电连接插 座内的电源电极之间还有一定距离, 仍是不能够直接的接触到插 座内的电源电极, 从而极大地降低了触电危险。 另外, 防护门组 件还可以很好的进行电连接插座内的金属触点的防尘。
优选的, 在所述底座与所述第二金属触点之间设有顶紧弹 簧。 由于金属触点在使用一段时间后会发生弹性下降或者变形, 但顶紧弹簧由于其采用的材料和螺旋结构导致其失效时间比金属 触点要慢得多, 因此可以使金属触点在顶紧弹簧的压力下继续保 持足够的夹紧力, 保证电极之间的接触率和电连接的可靠性。
优选的,所述第一金属触点还包括:至少一个第一接地电极; 所述第二金属触点包括: 至少一个第二接地电极; 在所述插头的 至少一个第一接地电极插入所述电连接插座并旋转到所述导电位 置之前的位置, 所述至少一个第二接地电极分别与所述至少一个 第一接地电极接触导通。 通过旋转方式使接地电极在先于电源电 极接通的位置就完成接通, 可以实现接地电极要求先于电源电极 接通, 晚于电源电极断开的安全要求, 消除了传统的直插式电连 接装置由于插入方向有一定倾斜导致接地电极要求与电源电极同 时接通, 或晚于电源电极接通而可能对用户造成的触电危险。
优选的, 所述第一金属触点的垂直于插入方向的截面为圆 弧, 各个第一金属触点的圓弧截面具有共同的圆心。 这种圓弧截 面在同心的结构下利于电连接插头在电连接插座中的旋转操作。

如图 1所示,为本发明一旋转式电连接装置实施例中的电连 接插头的立体结构示意图。 在本实施例中, 旋转式电连接装置的 电连接插头 100与电连接插座配合相配合, 该电连接插头 100具 有插头本体 101, 在插头本体 100的底面设有至少两个第一金属 触点, 第一金属触点可以包括至少两个第一电源电极, 还可以包 括至少一个第一接地电极,第一接地电极可略长于第一电源电极, 以便紧急断电时插头被拔出时, 第一接地电极能晚于第一电源电 极断开。 在本实施例中, 插头本体 101的底面设置有两个第一电 源电极的金属触点 102和 103 (图 2中示出)和一个第一接地电 极的金属触点 104。
如图 2所示,为图 1电连接插头的另一方向的立体结构示意 图。 在图 2中, 第一金属触点的垂直于插入方向的截面可采用圆 弧截面, 且各个第一金属触点的圓弧截面具有共同的圓心, 这种 圆弧截面在同心的结构下利于电连接插头在电连接插座中的旋转 操作。 其他的第一金属触点的截面形状也是可以采用的, 例如平 板式的第一金属触点或者圆棍体的第一金属触点等。
在插头本体 101底面的各个第一金属触点相对于中心可以具 有相同的半径, 也可以具有不同的半径。 相同半径的第一金属触 点更为标准化, 便于制造和使用, 而第一金属触点可以通过设置 不同半径来调整第一金属触点之间的距离, 可以使其达到金属触 点间的安全距离, 而在符合安全距离的情况下, 如果要在功率较 大的场合使用, 采用相同半径的金属触点则需要制造较大尺寸的 电连接插头, 而通过设置不同半径的第一金属触点则不需要较大 尺寸的电连接插头, 从而减小电连接插头的尺寸。
另外, 通过设置不同半径的第一金属触点, 还可以确保用户 使用时不会插错。 与第一金属触点相配合的插座中的第二金属触 点也可以采用相同的半径, 以地线电极和电源电极采用不同半径 的电连接插头为例, 电连接插座中的地线电极和电源电极也相应 地采用不同半径, 如果用户使用时不小心将地线电极的金属触点 对准电连接插座的电源电极的插入孔, 则会由于半径不同无法插 入, 从而提醒用户该插入位置并非正确的插入位置, 需要用户自 己调整到正确的插入位置进行电连接插头的插入。
在图 1的实施例中,插头本体 101的侧壁还可以设置限位凸 块 105, 该限位凸块 105可以起到插头本体 101在转动到预设角 度后的转动限制, 通过对转动预设角度的限制可以金属触点能够 旋转到需要的接触位置以保证足够的接触面积, 而不会因旋转不 足或过度而造成接触面积过小或者虚接的情况。
在限位凸块 105与插头本体 101之间设置有定位弹簧 107, 该定位弹簧 107可以使限位凸块 105在径向上来回运动, 当限位 凸块 107的表面受压时, 限位凸块 105会缩入插头本体 101, 当 压力解除时, 限位凸块 105会在定位弹簧 107的作用下复位, 伸 出插头本体 101。
在另一实施例中, 插头本体 101 上还可以设置与限位凸块 105 联动的解除限位凸块 106, 用户可以通过压下解除限位凸块 106来使限位凸块 105缩回插头本体 101,从而解除限制电连接插 头的旋转限制。
在插头本体 101的底面上还可以设置导向孔,可以与电连接 插座上的旋转轴配合, 实现对电连接插头的旋转引导功能。
如图 3所示,为本发明一旋转式电连接装置实施例的正面分 解结构示意图。 电连接插座包括顶盖 200和底座 202, 顶盖 200 扣合在底座 202之上。 接下来分别对底座 202和顶盖 200的结构 进行说明。
如图 4所示,为本发明一旋转式电连接装置实施例中的电连 接插座的底座的结构示意图。 在底座 202内部设有至少两个第二 金属触点。 第二金属触点可以包括至少两个第二电源电极, 第二 电源电极在电连接插头的至少两个第一电源电极插入电连接插座 并旋转至预设角度的导电位置, 分别与至少两个第一电源电极接 触通电。 底座 202内还可以包括至少一个第二接地电极, 其中第 二接地电极在电连接插头的至少一个第一接地电极插入电连接插 座并旋转到导电位置之前的位置, 分别与电连接插头的至少一个 第一接地电极接触导通。
在本实施例中, 第二金属触点包括两个电源电极 203、 204 和一个接地电极 205。 其中接地电极 205比电源电极 203和 204 更长, 在电连接插头插入电连接插座后并旋转时, 由于接地电极 205的长度更长(图 4中示出) , 使得接地电极先于电源电极接 通。
在底座 202 的内部结构与第二金属触点之间设有顶紧弹簧 206。第二金属触点可以釆用一个金属片,也可以采用两个金属片。 在釆用一个金属片的实施例中, 顶紧弹簧将该金属片顶向插座内 部的绝缘结构, 电连接插头的金属触点旋转到金属片和绝缘结构 之间的空隙来完成电连接。
在釆用两个金属片的实施例中, 图 4也示出了这种情形, 电 连接插头的金属触点旋转到两个金属片之间形成的空隙来完成电 连接, 其中设置在两个金属片与插座内部结构之间顶紧弹簧可以 实现金属片之间的夹紧力。 旋转式电连接装置的电连接插座的金 属触点在使用一段时间后会发生弹性下降或者变形, 但顶紧弹簧 由于其采用的材料和螺旋结构导致其失效时间比金属触点要慢得 多, 因此可以使金属触点在顶紧弹簧的压力下继续保持足够的夹 紧力, 保证电极之间的接触率和电连接的可靠性, 从另一个角度 上, 也极大地提高了电连接装置的使用寿命。
在底座 202中还设置了引导电连接插头的第一金属触点从插 入位置旋至第二金属触点完成电连接的旋转引导机构。 旋转引导 机构可以设置在第二金属触点的切线方向上, 引导第一金属触点 从插入位置以切线方向旋至第二金属触点完成电连接。 旋转引导 机构可以包括设置在第一金属触点的插入位置和第二金属触点之 间的引导槽 207, 该引导槽 207在第二金属触点的切线方向上, 第一金属触点通过在引导槽 207中滑动就可以准确地与第二金属 触点接触, 方便用户操作。
在底座 202中, 还可以设置旋转轴 208, 可以与电连接插头 100 的导向孔配合, 也可以实现第一金属触点旋转到第二金属触 点完成电连接的旋转引导。 旋转轴 208和导向孔的配合还可以实 现插入导向的作用。
除了以上描述的旋转引导机构之外,还可以有其它的实现形 式, 例如在插座的底座 202设置导向孔, 在插头本体 101底部设 置与导向孔配合的旋转轴。 又例如: 通过插头本体 101的圓形轮 廓与插座的顶盖 200的圓形通孔结构或底座 202的圆形内腔之间 的配合。
为了使第一金属触点更容易的与第二金属触点磨擦接触,可 以在第二金属触点的金属片的边缘设置导引第一金属触点进入的 电连接导引结构, 例如弯折结构或者圆弧结构。
电连接插座的底座内的第二金属触点的垂直于插入方向的 截面可采用圆弧截面, 且各个第二金属触点的圆弧截面具有共同 的圆心, 第二金属触点可以与同样具有圓弧截面的第一金属触点 具有相同的圆心。 这种圆弧截面在同心的结构下利于电连接插头 在电连接插座中的旋转操作。 金属片采用圆弧截面, 在受到压紧 弹簧的压力后可以与具有圆弧截面的第一金属触点更紧密的接 触, 实现更高的接触率。 其他的第二金属触点的截面形状也是可 以采用的, 例如平板式的第二金属触点或者多圆弧截面的第二金 属触点等。
在底座的各个第二金属触点相对于中心可以具有相同的半 径, 也可以具有不同的半径。 相同半径的第二金属触点更为标准 化, 便于制造和使用, 而第二金属触点可以通过设置不同半径来 调整第二金属触点之间的距离, 可以使其达到金属触点间的安全 距离, 而在符合安全距离的情况下, 如果要在功率较大的场合使 用,采用相同半径的金属触点则需要制造较大尺寸的电连接插座, 而通过设置不同半径的第二金属触点则不需要较大尺寸的电连接 插座, 从而减小电连接插座的尺寸。
另外, 通过设置不同半径的第二金属触点, 还可以确保用户 使用时不会插错。 以地线电极和电源电极采用不同半径的电连接 插头为例, 电连接插座中的地线电极和电源电极也相应地采用不 同半径, 如果用户使用时不小心将地线电极的金属触点对准电连 接插座的电源电极的插入孔, 则会由于半径不同无法插入, 从而 提醒用户该插入位置并非正确的插入位置, 需要用户自己调整到 正确的插入位置进行电连接插头的插入。
在插座的底座 202内还设有绝缘结构,该绝缘结构包括隔离 各个第二金属触点的绝缘隔板 209, 该绝缘隔板 209可以具有统 一的直板形状, 也可以是由多个具有不同形状的绝缘板形成的绝 缘隔板 209。 通过绝缘隔板 209将各个第二金属触点在空间上分 割为多个半封闭的独立电极仓。 在图 4中, 两个电源电极 203、 204和接地电极 205均被绝缘隔板 209分割为上表面开放的半封 闭的三个独立电极仓, 绝缘隔板 209 不仅将电源电极 203、 204 和接地电极 205隔离, 还将与电源电极 203、 204和接地电极 205 连接的压紧弹簧 206分别隔离, 形成独立电极仓。
独立电极仓的形成可以增加第二金属触点之间的爬电距离 和电气间隙, 使第二金属触点之间达到安全距离, 从而避免电极 之间的短路, 提高电连接装置的安全系数。
如图 5所示, 为本发明一旋转式电连接装置实施例中的电连 接插座的顶盖的结构示意图。顶盖 200包括盖体 201,在盖体 201 上可以设置电连接插头 100插入的通孔 210,便于电连接插头 100 插入并通过圆柱形轮廓配合通孔 210转动; 也可以不设置通孔, 而直接在顶盖 200的表面设置便于第一金属触点沿切线方向运动 的滑槽。
在插座顶部的顶盖 200可以设置与插头本体 101的限位凸块 配合的限位横向滑槽 211, 在限位横向滑槽 211的两端可以设置 垂直插入口 212和垂直拔出口 213。 其中垂直插入口 212便于插 头本体 101的限位凸块未电连接时进入限位横向滑槽 211, 垂直 拔出口 213便于插头本体 101的限位凸块在直接断开电连接时脱 离限位横向滑槽 211 插头本体 101的限位凸块和插座的限位横向滑槽 211构成了 使插头 100的第一金属触点在插入插座并旋转预定角度后卡紧的 电连接锁紧机构。
除了上述的电连接锁紧机构之外, 电连接锁紧机构还可以有 其它实现方式, 例如在插头本体设置限位销, 在插座顶部设置与 限位销配合的限位孔, 在限位销和插头本体之间设有复位弹簧, 限位销受到复位弹簧的作用从插头本体的底部伸出。 当插头底面 接触到插座时, 限位销受到插座表面的压力而缩回插头本体, 而 当插头旋转至预设角度后, 限位销对准限位孔, 此时限位销由于 受到复位弹簧的作用, 伸出插头本体, 并进入限位孔, 从而完成 电连接位置的锁定。
在需要将电连接插头旋转回初始位置拔出的场景,可以在插 头本体的侧壁设置与限位销联动的可延轴向发生位移的解除限位 凸块, 用户通过向拔出方向的力拨动解除限位凸块, 带动限位销 脱离限位孔, 从而解除电连接位置的锁定。
如图 6所示,为本发明另一旋转式电连接装置实施例的正面 分解结构示意图。 与图 3实施例相比, 本实施例增加了防护门组 件, 电连接插座包括顶盖 200、 防护门组件 400和底座 202, 顶盖 200扣合在底座 202之上。
如图 7所示,为本发明一旋转式电连接装置实施例中的电连 接插座的防护门组件的立体结构示意图。 防护门组件 400包括相 对于底座 202可转动的动片 401, 动片 401具有垂直贯通的容纳 部分, 容纳部分内设有遮挡部分, 在非工作状态下, 动片 401的 容纳部分被遮挡部分所遮挡, 在工作状态, 动片 401的容纳部分 不被遮挡部分所遮挡。
容纳部分可以为至少两个用于容纳第一金属触点的通孔 402, 遮挡部分可以为可伸缩的挡块 405 (图 8中示出)或可弯折 的挡片 (图中未示出) , 挡块 405或挡片与动片 401之间设有复 位弹簧 406。 在动片 401上还可以设置中心孔 404。
用户在使用旋转式电连接装置时,可以将插头本体 101底部 的第一金属触点插入动片 401的通孔 402中, 由于第一金属触点 的压力, 使得挡块 405被挤开, 压缩复位弹簧 406, 此时第一金 属触点穿过通孔 402, 以便在电连接插头 100与动片 401旋转后 与插座 202中的第二金属触点进行电连接。在拔出电连接插头时, 由于第一金属触点从通孔 402中脱离,挡块 405受到复位弹簧 406 的压力后复位, 重新挡住通孔 402, 从而实现了在非工作状态时, 挡住底座中的金属触点, 避免用户误操作导致的触电危险, 而在 工作状态下, 第一金属触电给予挡块一定的压力以克服复位弹簧 406的弹力, 从而穿过通孔 402。
动片 401在第一金属触点的带动下可以旋转, 以便第一金属 触点能够转至预设角度, 以实现与第二金属触点之间的电连接。 为了使动片 401在第一金属触点拔出后能够回到原始位置, 可以 在动片 401上设置用于使动片 401恢复到非工作状态下的位置的 复位弹簧, 例如与底座 202或顶盖 200之间设置复位弹簧(图中 未示出) , 该复位弹簧的一端连接在动片 401的弹簧安装柱上, 另一端安装在底座或顶盖内, 利用动片在转动预设角度后复位弹 簧所具有的拉力, 使得动片回到原始位置。
为了防止动片 401 在非工作状态下被旋转到不合适的角度 (例如通孔 402正对着第二金属触点) , 需要对动片 401进行限 位,因此在底座 202中可以设置用于在非工作状态下限制动片 401 的旋转运动的动片限位结构。
该动片限位结构的一种具体实现方式包括设在动片 401上的 限位槽 403, 以及设置在底座 201 内与限位槽 403配合的限位销 (图 4中示出) , 在限位销与底座 201之间还设有复位弹簧(图 中未示出) 。 在非工作状态下, 限位销受到复位弹簧的压力进入 限位槽 403, 阻挡动片 401转动, 而用户在使用时可以通过将限 位销退出限位槽 403的方式解除动片 401的限位。 例如将限位销 设于动片 401的容纳部分的下方, 使其可以受到第一金属触点的 压力向下发生位移, 从而退出限位槽 403。 推动限位销的第一金 属触点可以釆用第一接地电极, 也可以采用第一电源电极。
如图 9所示,为本发明又一旋转式电连接装置实施例的正面 分解结构示意图。 与图 3实施例相比, 在第二金属触点的上部设 置了绝缘盖 300,从上部遮挡住第二金属触点,通过绝缘隔板 209 和绝缘盖 300可以将各个第二金属触点在空间上分割为多个封闭 的独立电极仓。 在图 4 中, 两个电源电极 203、 204和接地电极 205均被绝缘隔板 209和绝缘盖 300分割为封闭的三个独立电极 仓,绝缘隔板 209不仅将电源电极 203、204和接地电极 205隔离, 还将与电源电极 203、 204和接地电极 205连接的压紧弹簧 206 分别隔离, 形成独立电极仓。
独立电极仓的形成可以增加第二金属触点之间的爬电距离 和电气间隙, 使第二金属触点之间达到安全距离, 从而避免电极 之间的短路, 提高电连接装置的安全系数。
如图 10所示, 为本发明一旋转式电连接装置实施例中的电 连接插座的绝缘盖的立体结构示意图。 绝缘盖 300可以是具有一 定厚度的薄板, 在绝缘盖 300设有便于第一金属触点以切线方向 旋至第二金属触点的圆弧形通槽 302, 在绝缘盖 300的外缘可以 设置用于固定绝缘盖 300,使其不会发生转动的凸部 301, 该凸部 301可以与底座 202内部的结构卡住。 在绝缘盖 300的中心可以 设置中心孔 303, 底座 202或插头本体 101底部设置的的旋转轴 可以穿过该中心孔 303, 在中心孔 303也可以设置出与旋转轴配 合, 且阻碍绝缘盖转动的结构, 例如, 在底座 202的旋转轴的轴 壁设置凸起的肋板,在中心孔 303的孔壁设置与肋板配合的通槽。 为使绝缘盖 300能够稳定的盖合在绝缘隔板 209之上,在绝 缘盖 300的底部可以设置可以嵌入绝缘隔板 209形成的空腔的嵌 入件 304 (图 11中示出) , 通过嵌入件 304和绝缘隔板 209之间 的嵌入关系, 也可以使得绝缘盖 300不至于发生转动, 并且能够 造成比较封闭的独立电极仓。
在图 12 中还给出了本发明再一旋转式电连接装置实施例的 正面分解结构示意图。 与图 3实施例相比, 本实施例中电连接插 座 200包括顶盖 201、 防护门组件 400、 绝缘盖 300和底座 202, 顶盖 201扣合在底座 202之上。
下面结合本发明的一个旋转式电连接装置的实施例 (图 12 实施例) 来说明在使用过程中装置的各部件的运转流程。
用户手持电连接插头插入电连接插座后,其中电连接插头的 限位凸块对准电连接插座的顶盖设置的限位横向滑槽的垂直插入 口, 插入后, P艮位凸块进入垂直插入口, 同时电连接插头的两个 第一电源电极和一个第一接地电极穿过防护门组件上的通孔和绝 缘盖上的圆弧形通槽插入到引导槽, 插座底座的第二旋转轴穿过 防护门组件上的中心孔和绝缘盖上的中心孔插入到插头本体底部 的第一导向孔。
防护门组件上的通孔中的挡块受到第一电源电极和第一接 地电极的压力后, 压缩复位弹簧, 从而开放通孔, 使得第一电源 电极和第一接地电极均能转过通孔。 其中第一接地电极向下将正 对的限位销挤出动片上的限位槽, 从而解除了限位销对动片的转 动限制。
用户对插头本体施以一定的扭矩, 电连接插头的两个第一电 源电极和一个第一接地电极沿着引导槽滑动,带动动片一起转动, 其中电连接插座的第二接地电极与插头的第一接地电极先于两个 第二电源电极与第一电源电极接触。 同时, 限位凸块受到滑槽内 壁的压力缩入插头本体, 并压缩限位凸块与插头本体之间的定位 弹簧。 当旋转到预设角度后, 第一电源电极旋入第二电源电极的 两片金属片之间, 受到金属片自身的夹紧力和压紧弹簧的弹力的 作用, 使得第一电源电极和第二电源电极紧密接触, 同时第一接 地电极也与第二接地电极紧密接触, 限位凸块滑到限位横向滑槽 的垂直拔出口卡住, 限制插头本体不能向前和向后旋转, 可防止 因插头本体的回旋而意外断电的发生。
当用户希望断开电连接时, 可以选择两种方式: 一种是直接 拔出, 一种是旋回插入前位置再拔出。
直接拔出的方式的过程包括: 需要断电时, 特别是在遇紧急 情况需快速断电时,用户对插头本体施以与插入方向相反的拉力, 在此拉力的作用下, 插头本体底部的第一金属触点克服插座的第 二金属触点的压紧力与第二金属触点瞬间脱离, 完成断电。 与此 同时, 插头本体上的限位凸块从电连接插座顶部的限位横向滑槽 的垂直拔出口脱出。
防护门组件的通孔中的挡块由于失去了第一金属触点的压 力, 受到复位弹簧的压力重新挡住通孔, 同时防护门组件受到与 底座之间的复位弹簧的拉力而重新返回原始位置。
第一接地电极可以设计成较第一电源电极更长的方式,这样 第一电源电极与第二电源电极之间断开连接时, 第一接地电极与 第二接地电极之间仍保持良好的接触, 这样保证了先断电后断接 地的连接方式。
旋回插入前位置再拔出的过程包括: 首先给插头本体上的解 除限位凸块施加压力, 由于该解除限位凸块与限位凸块联动, 因 此限位凸块缩入插头本体, 解除与垂直拔出口的卡住状态。 然后 用户给插头本体再施加与接通电源时旋入方向相反的扭矩力, 使 插头本体回旋至接通电源时的旋转开始位置。
在此旋转过程中,第一金属触点和第二金属触点的接触面积 逐渐减少, 直至完全脱离完成断电。 防护门组件的通孔中的挡块 由于失去了第一金属触点的压力, 受到复位弹簧的压力重新挡住 通孔。 而这时第一接地电极在断电时仍与第二接地电极保持良好 的接触状态, 这样保证了先断电后断接地的连接方式。 在此旋转 过程中, 限位凸块沿限位横向滑槽内壁滑动。
在插头本体回旋到位时, 用户施以与插入方向相反的拉力, 使第一金属触点从电连接插座脱离。 至此完成旋回插入前位置再 拔出的断电方式并恢复至初始位置。
本发明的旋转式电连接装置中的电连接插头和电连接插座 均可以单独制造和使用, 其中电连接插座还可以通过组合多个电 连接插座形成插线板, 插线板中的多个电连接插座可以沿直线顺 序排列, 也可以沿多边形、 圆形、 椭圓形等进行排列。
最后应当说明的是:以上实施例仅用以说明本发明的技术方 案而非对其限制; 尽管参照较佳实施例对本发明进行了详细的说 明, 所属领域的普通技术人员应当理解: 依然可以对本发明的具 体实施方式进行修改或者对部分技术特征进行等同替换; 而不脱 离本发明技术方案的精神, 其均应涵盖在本发明请求保护的技术 方案范围当中。
