Description

一种新型预制装配式快装电气管线 技术领域
本发明涉及建筑电气管线施工技术领域，尤其涉及一种新型预制装配式快装电气管线。
背景技术
在建筑电气设计与施工中，入户的电气末端管线目前多采用保护管内布线的方法，施工程序依次为：剔槽、埋管、穿线、接线等。为了便于管内穿线，必须在线管敷设时先在管内预留穿线铁丝，并对保护管的端头进行打磨处理以防止穿线时刮坏电线，为使穿线顺畅，做好管口预处理，在转弯和分支处按照施工规范设置穿线盒与接线盒，现场施工中弯管和管间连接需要采用专用工具，接线必须按照电工规范进行。
近年来我国建筑市场的熟练技工短缺，人工费用快速增加；然而对于电气末端管线一直还在延用传统低效的施工方法，这些施工工序都必须在现场完成，存在操作的工序多、工时长、效率低、作业量大，技术要求高，维修和更换困难，接线出错率高，装配一致性差等痛点。

具体实施方式
下面将结合附图以及具体实施例来详细说明本发明，其中的示意性实施例以及说明仅用来解释本发明，但并不作为对本发明的不当限定。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施方式例如能够以除了在这里图示或描 述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
如图1、图2所示，一种新型预制装配式快装电气管线，包括管线头部1、电线2、护管3。
所述管线头部1包括内芯101和包覆层102。
所述内芯101的一端插入所述护管3内、与在所述护管3内的所述电线2连接；所述内芯101的另一端设置外接端1011，所述外接端1011位于所述护管3之外。
所述包覆层102从外接端1011包覆至所述护管3上，所述包覆层102与所述内芯101封装为一体结构。
当外接端是母头时，在所述包覆层102上留有外接端1011的导通孔。
新型预制装配式快装电气管线，实际施工布置时可以直接使用，减少工序、降低工时、效率高、作业量小，对工人技术要求低，维修和更换方便，接线不容易出错，装配一致性好；还可以适用不同的现场布线需求。
双层的管线头部1既实现了管线的预制装配，同时保证管线头部与护管连接的紧密稳定性。
在这里外接端1011可以直接与其他电气管线连接，也可以直接外接电子元件或是电器等，因此外接端根据实际使用需要设置为公头或是母头或是某种具体的连接形式，不做限定。
在这里包覆层102在包覆护管3时，在护管3上的包覆长度根据实际使用需要进行设定，通常包覆的与内芯插入长度相当。
在某些实施例中，所述护管是柔性、可弯曲软管；例如所述护管是金属螺旋管，也可以是其他材质管，根据实际使用的需要进行选择；另外护管也可以选择是硬质管。
在这里虽然附图1和附图2中显示的是电线的两端分别安装有管线头部，但是在某些实施例中，管线头部根据实际电线连接的方式可以更多端的选择，例如三条或是更多条电线的连接，则需要更多个管线头部的连接端；实现快速连接。
在某些实施例中：所述内芯101横截面的直径、在内芯轴向上呈中间大两端小的变化。
直径的变化可以直接阶梯式变化，例如直径不同的多段组合(如图1—图5所示)；或者逐渐变化例如纺锤形；这种变化的直径在其两端安装时，可以限位，快速安装到位。
在某些实施例中：插入所述护管端部之内的所述内芯101与所述护管3固定连接(固定方式可以是依靠摩擦力过盈配合、或是卡接、螺旋连接等等)。增加连接的稳定性，不只是依靠包覆层保证管线头部1与护管3的连接稳定。
在某些实施例中：所述护管3与所述管线头部1贴合面缠有高温胶带。这样可以保证护管3在涂胶过程中不会窜动移位。
在某些实施例中：在所述管线头部1上设置有防呆结构1012。
如图1—图5所示，这里防呆结构1012是一个扇形端面，这里电线是三芯线，扇形端面确定了连接的方向性，有效的避免误操作。
防呆结构还可以是其他形式，比如D型面或是T型面等，或者配合凹槽等。
在某些实施例中：所述管线头部1上设置防水结构。例如在管线头部1上设置环形槽103，环形槽内嵌有密封圈，保证管线头部1在连接过程中防水防尘。
在这里环形槽根据实际情况可以设置一条或是两条，或是更多条。
在某些实施例中：所述电线2为单芯线、两芯线、三芯线、四芯线、五芯线、六芯线中的任意一种。根据实际使用的需要选择，不做限定。
在某些实施例中：还包括快接壳4，所述快接壳4与所述管线头部1具有联动受力位置，所述快接壳4上设置有连接端，所述连接端用于固定管线头部与其他部件连接。
在某些实施例中，更具体的结构可以是将快接壳4套在所述管线头部1之外，让所述快接壳4后部抵在所述管线头部1后端形成联动受力位置，然后所述快接壳4前部设置连接端用于管线头部外接其他部件(例如管线或是电子元器件等等)。所述连接端为螺旋连接或卡接或者其他连接方式，根据实际使用的需要进行选择，优选螺旋连接。
在这里当电线整根作为连接线使用时，为了实现快速对接之后的使用，增加一个快接壳，快接壳的使用可以起到保护管线头部1的作用，同时由于管线头部是对接的，快接壳的使用可以避免对接脱落，保证连接紧密稳定。
在这里公开一个与快接壳4对接的对接器5结构，这里根据实际的情况对接器可以是两通、三通(例如T型或Y型或F型)、四通(例如十字型)等等，对接器内的芯体根据实际形状 对应设置，通过这样的对接器可以快速的实现通电线路的变向、续接、分路等等功能。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
