为了使本发明所要解决的技术问题、 技术方案及有益效果更加清楚明白, 以下结合附图 及实施例, 对本发明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 释本发明, 并不用于限定本发明。
图 4所示为本发明一实施例中接线盒 100的示意图。 接线盒 100包括壳体 120和连接部 150。 连接部 150设于壳体 120中, 并可与其他元件连接。
具体地, 壳体 120可以为一中空的大致呈长方体的结构。 壳体 120包括第一壁 122如顶 壁(当接线盒 100处于图 4所示位置时)、与第一壁 122相对且间隔设置的第二壁 125如底壁
(当接线盒 100处于图 4所示位置时)、 位于第一壁 122与第二壁 125之间并将第一壁 122、 第二壁 125两侧两别连接的二侧壁 126, 以及分割结构 128。 第一壁 122、 第二壁 125和二侧 壁 126围成一内部空间; 分割结构 128设置在由第一壁 122、 第二壁 125和二侧壁 126围成 的内部空间中并将该内部空间分割成多个第一安装空间 1282。第一壁 122上的一端如左端(当 接线盒 100处于图 4所示位置时) 上设有凸出部 1223。 凸出部 1223大致垂直于第二壁 125 并沿着远离第二壁 125的方向延伸从而使得第一壁 122的外表面呈台阶状。凸出部 1223上设 有第二安装空间 1225, 第二安装空间 1225与对应的第一安装空间 1282联通用以安装连接部 150。
如图 5所示, 连接部 150包括本体 152、 第一连接端 153、 第二连接端 155和螺栓端子 156。 其中, 本体 152可安装在壳体 120中, 本体 152内部形成有安装孔 1523 ; 安装孔 1523 用于收容线缆 40 (如图 6所示)。 螺栓端子 156穿过第一壁 122和本体 152, 并与位于安装孔 1523中的线缆 40连接。 第一连接端 153的第一端与本体 152连接, 第一连接端 153的第二端从第一连接端 153 的第一端弯折延伸, 用以与接触器 20连接。在图 5所示的实施例中, 第一连接端 153包括第 一延伸部 1532、 第二延伸部 1533、 第三延伸部 1535和第四延伸部 1536。 第一延伸部 1532 延伸到安装孔 1523内并与本体 152连接。第二延伸部 1533从第一延伸部 1532向下(当第一 连接端 153处于图 5所示位置时)弯折延伸形成并大致垂直于第一延伸部 1532。 第三延伸部 1535从第二延伸部 1533向左 (当第一连接端 153处于图 5所示位置时) 弯折延伸形成, 第 三延伸部 1535大致垂直于第二延伸部 1533并大致平行于第一延伸部 1532。第四延伸部 1536 从第三延伸部 1535向下弯折延伸形成并大致垂直于第三延伸部 1535。 第一延伸部 1532、 第 二延伸部 1533、 第三延伸部 1535和第四延伸部 1536的具体形状可根据第一安装空间 1282 中的具体形状等进行调整, 以便于将第一连接端 153安装在对应的第一安装空间 1282中。此 外, 为了使接线盒 100较为稳固地安装在接触器 20上, 第四延伸部 1536的边缘上可进一步 设有缺口 1537。
第二连接端 155设置在第一连接端 153上。 在图 5所示的实施例中, 第二连接端 155包 括第一延伸结构 1552、第二延伸结构 1553和第三延伸结构 1556。第一延伸结构 1552大致垂 直地设置在第三延伸部 1535的一边, 并从第三延伸部 1535向上 (当第一连接端 153处于图 5所示位置时)延伸。 第二延伸结构 1553从第一延伸结构 1552弯折至与第三延伸部 1535相 对且大致平行于第三延伸部 1553。 第三延伸结构 1556从第二延伸结构 1553的一边大致垂直 向上延伸; 如图 4所示, 当连接部 150组装到壳体 120时, 第三延伸结构 1556延伸到第二安 装空间 1225内, 用于与电阻线 30连接 (如图 6所示)。
上述为本发明一实施例中接线盒 100的结构示意图;下面以图 6所示的接触器装置为例, 简述接线盒 100与接触器 20、 电阻线 30和线缆 40的连接关系。
如图 6所示, 接线盒 100可通过第一连接端 153与接触器 20连接。将接线盒 100与接触 器 20连接后,第二连接端 155的第三延伸结构 1556位于螺栓端子 156与接触器 20之间; BP , 相对于螺栓端子 156而言, 第二连接端 155的第三延伸结构 1556更加接近接触器 20。 换言 之, 本体 152位于接线盒 100的一侧而第一连接端 153和第二连接端 155位于接线盒 100的 相对的另一侧; 或者说, 第一连接端 153和接触器 20之间的连接处、 以及电阻线 30与第二 连接端 155之间的连接处位于接线盒 100的一侧,本体 152与线缆 40之间的连接处位于接线 盒 100的相对的另一侧; 或者说, 电阻线 30与第二连接端 155之间的连接处位于, 第一连接 端 153和接触器 20之间的连接处与本体 152与线缆 40之间的连接处之间。 这样设置, 电阻 线 30在接线盒 100的一侧与第二连接端 155的第三延伸结构 1556连接,而线缆 40则在接线 盒 100的另一侧与螺栓端子 156连接,即电阻线 30可与第二连接端 155的第三延伸结构 1556 连接而无需跨越接线盒 100, 这样既利于紧固安装接线盒 100, 也有利于线缆 40的连接安装。 图 7和图 8为本发明另一实施例中接线盒 200的结构示意图。如图 7-8所示,接线盒 200 包括壳体 220、连接部 250和盖板 260。连接部 250设于壳体 220与盖板 260之间, 并可与其 他元件连接。
如图 8所示, 壳体 220为两层结构, 如第一层 221和设于第一层 221上方的第二层 223。 第一层 221包括间隔设置的多个第一安装空间 2212。 第二层 223包括间隔设置的多个第二安 装空间 2232。 在图 8所示的实施例中, 第二安装空间 2232—一对应于第一安装空间 2212。 第二层 223上进一步形成有多个连接孔 2236。 连接孔 2236大致垂直地贯穿第二层 223的顶 部后与第二安装空间 2232联通, 且连接孔 2236—一对应于第二安装空间 2232。
此外, 第二层 223的顶部呈台阶状, 包括基部 2237和台阶部 2238。 基部 2237和台阶部 2238上分别设有多个用于安装螺丝的穿孔 2239。
如图 9所示, 连接部 250包括本体 252、 第一连接端 253、 第二连接端 255和螺栓端子 256。 其中, 本体 252可安装在壳体 220的第一层 221中, 本体 252内部形成有安装孔 2523 ; 安装孔 2523用于收容线缆。 螺栓 156穿过台阶部 2238的穿孔 2239和本体 252, 并与位于安 装孔 2523中的线缆连接。
第一连接端 253的第一端与本体 252连接, 第一连接端 253的第二端从第一连接端 253 的第一端弯折延伸, 用以与接触器连接。 在图 9所示的实施例中, 第一连接端 253包括第一 延伸部 2532、 第二延伸部 2533、 第三延伸部 2535和第四延伸部 2536。 第一延伸部 2532延 伸到安装孔 2523内并与本体 252连接。第二延伸部 2533从第一延伸部 2532向下(当第一连 接端 253处于图 9右侧所示位置时)弯折延伸形成并大致垂直于第一延伸部 2532。 第三延伸 部 2535从第二延伸部 2533向左 (当第一连接端 153处于图 9右侧所示位置时) 弯折延伸形 成, 第三延伸部 2535大致垂直于第二延伸部 2533并大致平行于第一延伸部 2532。 第四延伸 部 2536从第三延伸部 2535 向上弯折延伸形成并大致平行于第三延伸部 2535。 第一延伸部 2532、 第二延伸部 2533、 第三延伸部 2535和第四延伸部 2536的具体形状可根据第一层 221 的第一安装空间 2212中的具体形状等进行调整,以便于将第一连接端 253安装在对应的第一 安装空间 2212中。
第二连接端 255设置在第一连接端 253上。 在图 9所示的实施例中, 第二连接端 255包 括第一延伸结构 2552、第二延伸结构 2553和第三延伸结构 2556。第一延伸结构 2552大致垂 直地设置在第三延伸部 2535的一边, 并从第三延伸部 2535向上 (当第一连接端 253处于图 9右侧所示位置时)延伸。第二延伸结构 2553从第一延伸结构 2552弯折至与第三延伸部 2535 相对且大致平行于第三延伸部 2535。 第三延伸结构 2556从第二延伸结构 2553的一边沿着大 致平行于第三延伸部 2535的方向延伸。当连接部 250组装到壳体 220时,第三延伸结构 2556 延伸到第二安装空间 2232内, 螺栓 156穿过基部 2237上的穿孔 2239后旋入第三延伸结构 2556上的通孔 2557中从而将第二连接端 255与第二层 223固定, 此时, 第三延伸结构 2556 可用于与插入到连接孔 2236中的电阻线连接。
盖板 260设置在壳体 220上用于与线缆连接的一端, 与台阶部 2238接触。盖板 260上间 隔设置有多个插孔 2602, 插孔 2602与台阶部 2238上的穿孔 2239对应设置用于供线缆插入 到壳体 220中与对应的本体 252连接。
图 10为本发明一实施例中接线盒的第一连接端 353与第二连接端 355的结构示意图。如 图 10所示, 第一连接端 353的结构与图 5中第一连接端 153的结构基本相同, 也包括第一延 伸部 3532、 第二延伸部 3533、 第三延伸部 3535和第四延伸部 3536。 第二连接端 355大致呈 L形, 包括第一部分 3552和与第一部分 3552大致垂直地第二部分 3553。 第二连接端 355的 第一部分 3552与第一连接端 353的第三延伸部 3535贴合, 而且, 第二连接端 355的第一部 分 3552与第一连接端 353的第三延伸部 3535可通过焊接或铆接等方式组装在一起。
综上所述, 本发明实施例提供的接线盒可具有下述优点:
1、本发明实施例提供的接线盒中包括第一连接端和第二连接端, 其中第一连接端可用于 与接触器连接, 而第二连接端可用于与电阻线连接, 这样, 电阻线可与第二连接端连接而无 需跨越接线盒, 这样既利于紧固安装接线盒, 也有利于线缆的连接安装。
2、 本发明实施例提供的接线盒还可用于标准的接触器中, 此时, 第二连接端还可用作信 号端子, 用以提供接线盒的信号从而进行测试。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 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, 均应包含在本发明的保护范围之内。
