滑动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， 具体涉及一种滑动式电连接装置， 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， 无 法保证先接地后导电； 通电后插头带电部分可能有棵露， 则对操 作者有安全隐患。 另外可能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采 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 一种滑动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滑动式电连接 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 触点；
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滑至所述第二 金属触点完成电连接的滑动引导机构。
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， 再滑动接通的电连接方式， 基于滑动引导机构可以 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， 借助滑动引导机构进行滑动接 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， 所述插座的底座内还设有绝缘结构， 所述绝缘结构 包括隔离各个第二金属触点的绝缘隔板， 通过所述绝缘隔板将各 个第二金属触点之间分割为半封闭的独立电极仓。 通过绝缘隔板 可以提高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。 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导致的短路， 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。
在上述技术方案中， 底座与金属触点之间设置有顶紧弹性 体， 其中弹性体优选弹簧， 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滑动的动片， 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 使滑动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，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滑动到所述导电位 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 第一接地电极接触通电。 通过滑动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， 由于通电后插头带电部分可能有棵露 而可能对用户造成的触电危险。
优选的，所述第一金属触点与所述第二金属触点的电连接接 触面为平面。 平面的接触方式便于第一金属触点滑动， 同时平面 的接触方式的接触更紧密， 接触率更高。
为实现上述目的， 本发明的另一方面提供了一种电连接插 头， 具有插头本体， 在电连接插头的底面设有至少两个第一金属 触点。 所述第一金属触点包括： 至少两个第一电源电极， 所述第 一金属触点的电连接接触面为平面。
为实现上述目的， 本发明的又一方面提供了一种电连接插 座， 具有底座， 在底座内部设有至少两个第二金属触点， 所述第 二金属触点包括至少两个第二电源电极， 所述第二金属触点的边 缘延伸方向设有滑动引导机构„
为实现上述目的， 本发明的再一方面提供了一种插线板， 包 括至少两个的前述电连接插座。
基于上述技术方案， 本发明的一个实施例采用了先无电插 入， 再滑动接通的电连接方式， 基于滑动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， 借助滑动引导机构进行滑动接电可以尽 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； 在另一个实施例中，在底座与金属触点之间设置顶紧弹性体， 使得金属触点在顶紧弹性体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； 在又一个实施例中， 通 过在插座内金属触点间设置绝缘隔板可以提高各金属触点之间的 爬电距离和电气间隙，使其达到安全距离，避免电极之间的短路， 提高电连接装置的安全系数。 附图说明

下面通过附图和实施例，对本发明的技术方案做进一步的详 细描述。
如图 1所示，为本发明一滑动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， 滑动式电连接装置的 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 104, 在插头本体 104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 极断电。 在本实施例中， 插头本体 104的底面设置有两个第一电 源电极的金属触点 102 和 103 和一个第一接地电极的金属触点 101。
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， 第一金属触点的电连接接触面可采用平面， 且第 一金属触点均可采用平板式， 且各个第一金属触点相互间平行， 这种平行的第一金属触点的设置方式有利于电连接插头在电连接 插座中的滑动操作。 其他的第一金属触点的截面形状也是可以采 用的，例如圆弧形的第一金属触点或者圆柱体的第一金属触点等。
在插头本体 104底面的各个第一金属触点可呈基于底面中心 线对称的设置， 也可以选用非对称的方式设置。 对称设置的第一 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 过设置非对称的位置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， 采用对称设置方式的金属触点则需要 制造较大尺寸的电连接插头， 而通过设置非对称设置方式的第一 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。
在图 1的实施例中，插头本体 104的侧壁还可以设置限位凸 块， 该限位凸块可以起到插头本体 104在滑动到预设距离后的滑 动限制， 通过对滑动预设距离的限制可以金属触点能够滑动到需 要的接触位置以保证足够的接触面积， 而不会因滑动不足或过度 而造成接触面积过小或者虛接的情况。
在限位凸块与插头本体 104之间设置有定位弹簧，该定位弹 簧可以使限位凸块在径向上来回运动，当限位凸块的表面受压时， 限位凸块会缩入插头本体 104, 当压力解除时， 限位凸块会在定 位弹簧的作用下复位， 伸出插头本体。
在另一实施例中，插头本体 104上还可以设置与限位凸块联 动的解除限位凸块， 用户可以通过压下解除限位凸块来使限位凸 块缩回插头本体， 从而解除限制电连接插头的滑动限制。
在插头本体 104的底面上还可以设置导轨或导槽，可以与电 连接插座上的导槽或导轨相配合， 实现对电连接插头的滑动引导 功能。
如图 3所示，为本发明一滑动式电连接装置实施例的正面分 解结构示意图。其中，电连接插座包括顶盖 200、防护门组件 300、 绝缘盖 500和底座 400， 顶盖 200扣合在底座 400之上。 接下来 分别对底座 400、绝缘盖 500、防护门组件 300和顶盖 200的结构 进行说明。
如图 4所示，为本发明一滑动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 400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 并滑动至预设位移的导电位置， 分别与至少两个第一电源电极接 触通电。 底座 400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 座并滑动到导电位置之前的位置， 分别与电连接插头的至少一个 第一接地电极接触通电。
在本实施例中， 可采用向某个方向滑动的方式， 其滑动可以 是直线滑动， 也可以设计成曲线滑动， 或者根据需要设计成既包 括曲线也包括直线的滑动方式。
在本实施例中， 第二金属触点包括两个电源电极 406、 407 和一个接地电极 405。 其中接地电极 405比电源电极 406和 407 更长， 在电连接插头插入电连接插座后并滑动时， 由于接地电极 405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 400的内部结构与第二金属触点之间设有顶紧弹性体 (如图 4中的顶紧弹簧 408 ) 。 第二金属触点可以采用一个金属 片， 也可以采用两个金属片。 在采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 触点滑动到金属片和绝缘结构之间的空隙来完成电连接。
在采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滑动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性体可 以实现金属片之间的夹紧力。 滑动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， 顶紧弹性 体的失效时间比金属触点要慢得多， 例如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性体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 400中还设置了引导电连接插头的第一金属触点从插 入位置以滑至第二金属触点完成电连接的滑动引导机构。 滑动引 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， 该引导槽在第二金属触点的边缘延伸方向上， 第 一金属触点通过在引导槽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 400或顶盖 200上， 还可以设置导槽或导轨， 与电连 接插头 100的插头本体 104的底面上的导轨或导槽相配合， 也可 以实现第一金属触点滑动到第二金属触点完成电连接的滑动引 导。
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电连接接触平面采 用平面方式（平板式） ， 且各个第二金属触点可平行设置。 这种 平板式结构的第二金属触点便于电连接插头在电连接插座中的滑 动操作。 金属片采用平面式接触， 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实现更紧密的接触， 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 圆弧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可呈基于底面中心线对称的设 置， 也可以选用非对称的方式设置。 对称设置的第二金属触点更 为标准化， 便于制造和使用， 而第二金属触点可以通过设置非对 称的位置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 , 采用对称设置的金属触点则需要制造较大尺寸的 电连接插座， 而通过设置非对称设置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。 在插座的底座 400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 401、 402、 403, 该绝缘隔板 401、 402、 403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。
在图 4中， 两个电源电极 406、 407和接地电极 405分别被 绝缘隔板 402、 403、 401分割为半封闭的三个独立电极仓， 绝缘 隔板 402、 403、 401 不仅将电源电极 406、 407和接地电极 405 隔离，还将与电源电极 406、 407和接地电极 405连接的压紧弹簧 408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。
在另一个实施例中，在第二金属触点的上部还可以设置绝缘 盖 500， 从上部遮挡住第二金属触点， 通过绝缘隔板 402、 403、 401和绝缘盖 500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 3中， 两个电源电极 406、 407和接地电 极 405均被绝缘隔板 402、 403、 401和绝缘盖 500分割为封闭的 三个独立电极仓， 绝缘隔板 402、 403、 401不仅将电源电极 406、 407和接地电极 405隔离， 还将与电源电极 406、 407和接地电极 405连接的压紧弹簧 408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， 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。
如图 5所示，为本发明一滑动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 500可以是具有一定 厚度的薄板， 在绝缘盖 500设有便于第一金属触点滑动到第二金 属触点的直线形通槽 501、 502、 503, 绝缘盖 500的外缘可以与 底座 400内部的结构卡住。
在绝缘盖 500上设置的通槽并不限定于直线形通槽，对于采 用以非直线方式 （例如曲线或部分曲线部分直线）滑动方式实现 电连接的滑动式电连接装置， 则可以设定与其滑行路线匹配的形 状的通槽。
为使绝缘盖 500能够稳定的盖合在绝缘隔板 402、 403、 401 之上，在绝缘盖 500的底部可以设置可以嵌入绝缘隔板 402、 403、 401之间的嵌入件 504 (图 6中示出）， 通过嵌入件 504和绝缘隔 板 402、 403、 401之间的嵌入关系， 形成比较封闭的独立电极仓。
如图 7所示， 为本发明一滑动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 300包括相对 于底座 400可滑动的动片， 动片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， 动片的容纳部分被遮挡部分 所遮挡， 在工作状态， 动片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，在 图 7中有通孔 301、 302、 303, 遮挡部分可以为可伸缩的挡块（图 中未示出）或可弯折的挡片 （图中未示出） ， 挡块或挡片与动片 之间设有复位弹簧。
用户在使用滑动式电连接装置时，可以将插头本体 104底部 的第一金属触点插入动片的通孔中， 由于第一金属触点的压力， 使得挡块被挤开， 压缩复位弹簧， 此时第一金属触点穿过通孔 301、 302、 303, 以便在电连接插头 100与动片滑动后与底座 400 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 301、 302、 303中脱离， 挡块受到复位弹簧的压 力后复位， 重新挡住通孔， 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的弹力， 从而穿过通孔。
动片在第一金属触点的带动下可以滑动， 以便第一金属触点 能够滑动预设位移， 以实现与第二金属触点之间的电连接。 为了 使动片在第一金属触点拔出后能够回到原始位置， 可以在动片和 底座 400之间设置复位弹簧 305 (图 8中示出） ， 该复位弹簧的 一端连接在动片的弹簧安装柱 304上， 另一端安装在底座内， 利 用动片在滑动预设位移后复位弹簧所具有的拉力， 使得动片回到 原始位置。
为了防止动片在非工作状态下被滑动到不合适的位置（例如 通孔正对着第二金属触点） ， 需要对动片进行限位， 因此在底座 400 中可以设置用于在非工作状态下限制动片滑动的动片限位结 构。
该动片限位结构的一种具体实现方式包括设在动片上的限 位槽， 以及设置在底座 400内与限位槽配合的限位销 （图中未示 出） , 在限位销与底座 400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， 阻挡 动片滑动， 而用户在使用时可以通过将限位销退出限位槽的方式 解除动片的限位。 例如将限位销设于动片的容纳部分的下方， 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。 推动限位销的第一金属触点可以采用第一接地电极， 也可以采用 第一电源电极。
如图 9所示，为本发明一滑动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。 在顶盖 200上可以设置电连接插头 100插入的通孔 201 ,便于电连接插头 100插入并在通孔 210移动 预设位移。 在插座顶部的顶盖 200可以设置与插头本体 104的限位凸块 配合的限位横向滑槽 （图中未示出） , 在限位横向滑槽的两端可 以设置垂直插入口和垂直拔出口。 其中垂直插入口便于插头本体 104 的限位凸块在未进行电连接前进入限位横向滑槽， 垂直拔出 口便于插头本体 104的限位凸块在直接断开电连接时脱离限位横 向滑槽。
插头本体 104的限位凸块和顶盖 200的限位横向滑槽构成了 使插头 100的第一金属触点在插入插座并滑动预定位移后卡紧的 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， P艮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， P艮位销受到插座表面的压力而缩回插头本体， 而 当插头滑动至预设位移后， 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滑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。
下面结合本发明的一个滑动式电连接装置的实施例来说明 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， 限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 缘盖上的直线形通槽插入到引导槽。
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穿过通孔。 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滑 动限制。
用户对插头本体施以预设方向（例如横向等）的推力， 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， 带动动片一起滑动， 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。 当滑动预设位移后， 第一电源电 极进入到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 向前和向后滑动， 可防止因插头本体的回退而意外断电的发生。
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， 一种是退回插入位置再拔出。
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。
退回插入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推动方向相反的推力， 使插头 本体退回到接通电源时的滑动开始位置。
在此滑动过程中，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。 在此滑动 过程中， 限位凸块沿限位横向滑槽内壁滑动。
在插头本体退回到位时， 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， 而限位凸块从垂直插入口退 出。 至此完成退回插入前位置再拔出的断电方式并恢复至初始位 置。
本发明的滑动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、 椭圆形等进行排列。
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。
