具体实施方式
下面结合实施例对本公开做进一步说明，但不局限于说明书上的内容。
在本公开各实施例中，普通管路部件为非导电冷媒管。
参考图1，本公开实施例提供一种接头，用于连通导电冷媒管10和普通管路部件，接头设置有绝缘件20。绝缘件20将导电冷媒管10与普通管路部件之间绝缘隔离。
使用时，先将导电冷媒管与接头连接，然后再将接头与非导电冷媒管连接，从而实现导电冷媒管与普通管路部件的连通。由于接头设置有绝缘件，可以通过绝缘将导电冷媒管与非导电冷媒管之间绝缘隔离，从而避免导电冷媒管传输的信号受到干扰，同时，也可以避免导电冷媒管传输的电力泄漏。
本公开的接头通过设置绝缘件，将导电冷媒管与非导电冷媒管之间绝缘隔离，从而避免导电冷媒管传输的信号受到干扰，也避免了导电冷媒管传输的电力泄漏，提高通过冷媒管导电的可靠性和安全性。
具体地，如图1所示的本公开的实施例一，公开了一种接头，接头用于连通导电冷媒管10和普通管路部件；接头设置有安装座21，安装座21将导电冷媒管10与普通管路部件之间绝缘隔离。
使用时，先将导电冷媒管10与接头连接，然后再将接头与普通管路部件连接，从而实现导电冷媒管10与普通管路部件的连通。由于接头设置有安装座21，可以通过绝缘将导电冷媒管10与普通管路部件之间绝缘隔离，从而避免导电冷媒管10传输的信号受到干扰，同时，也可以避免导电冷媒管10传输的电力泄漏。
本公开的接头通过设置安装座21，将导电冷媒管10与普通管路部件之间绝缘隔离，从而避免导电冷媒管10传输的信号受到干扰，也避免了导电冷媒管10传输的电力泄漏，提高通过冷媒管导电的可靠性和安全性。
另外，现有技术中，为了避免冷媒管路作为信号传输媒介时，信号的传输受到干扰，无法正常在室内机与室外机之间进行传输，采用的方式是通过绝缘胶将导电冷媒管10与普通管路直接粘接并绝缘。这种方式虽然可以实现绝缘性，但是在安装时花费的时间较长，而且由于是绝缘胶粘接，因此，无法拆卸，导致后期维修和维护困难，而且可靠性差。
通过本公开的接头，在装配时，可以通过接头连接，避免了胶粘的方式，安装更加方便和快捷，在维护更换时，拆卸过程也更加方便快捷，提高工作效率。
需要说明的是，在本实施例中，接头与普通管路部件是可拆卸连接的方式，例如：在装配时，可以通过卡接或螺接与普通管路部件连接，采用这种方式安装不仅方便快捷，而且更加可靠，而且，在维护更换时，拆卸过程也更加方便快捷，提高工作效率。
如图1和图2所示，接头还包括接口件30和锁紧件40，接口件30具有装配接口31；锁紧件40与接口件30连接，锁紧件40用于限位绝缘件20。使用时，通过接口 件30的装配接口31将导电冷媒管10与普通管路部件连通，从而实现冷媒的传输。通过设置锁紧件40可以将安装座21限位，从而防止安装座21的脱离，保证绝缘的可靠性和稳定性。
需要说明的是，装配接口31的装配方式是可拆卸地装配方式，装配接口31可以设置内螺纹或外螺纹，通过螺纹连接方式实现装配，也可以是卡接的方式。
进一步地，锁紧件40与接口件30可拆卸地连接。通过将锁紧件40与接口件30设置为可拆卸地连接方式，可以方便部件的更换或者维修，提高工作效率。
进一步地，如图1所示，锁紧件40与接口件30围成限位空间，部分绝缘件20位于限位空间内，具体地，限位座21位于限位空间内，部分绝缘件20位于限位空间的外部。通过将锁紧件40与接口件30围成限位空间，可以通过限位空间对安装座21进行限位，从而防止安装座21的脱离，保证绝缘的可靠性和稳定性。
需要说明的是，在本实施例中，导电冷媒管10插设在安装座21中，由于部分绝缘件20位于限位空间内，部分绝缘件20位于限位空间的外部。也就是说，如图1所示，安装座21设置在了导电冷媒管10与接口件30、锁紧件40之间，导电冷媒管10与接口件30、锁紧件40之间完全没有接触，从而实现了绝缘隔离，从而避免了导电冷媒管10传输的信号受到干扰，同时，也可以避免导电冷媒管10传输的电力泄漏。
在本实施例中，锁紧件40为锁紧螺母，锁紧件40与接口件30螺接，安装座21穿设在锁紧螺母内。进一步地，导电冷媒管10插设在安装座21中，锁紧螺母在上紧过程中对安装座21施加挤压力，使锁紧螺母与安装座21过盈配合，同时安装座21与导电冷媒管10过盈配合。通过采用锁紧螺母，可以同时对安装座21和导电冷媒管10进行锁紧固定，从而保证连接的可靠性和稳定性，而且安装和拆卸过程非常方便快捷，可以提高工作效率，降低时间成本。
需要说明的是，在本实施例中，锁紧螺母与接口件30之间螺纹连接，锁紧螺母底部为锥形设计，因此，在锁紧螺母上紧的过程中，会逐渐对安装座21进行挤压，使安装座21也对导电冷媒管10进行挤压，进而将安装座21与导电冷媒管10同时固定。在拆卸时，锁紧螺母反向倒退，挤压力逐渐减小，从而使安装座21、导电冷媒管10可以脱离，从而可以维修和更换。
如图3所示，接头具有用于装配普通管路部件的装配接口31；绝缘件20包括安装座21，安装座21内设置有用于连通装配接口31和导电冷媒管10的冷媒通道211。通过在安装座内设置冷媒通道211，使冷媒通道211与装配接口31连通，从而可以实现安装座21的绝缘侧与带电侧之间冷媒的流通，同时安装座还将接头绝缘隔离，在 保证冷媒流通的同时，实现导电冷媒管10与普通管路部件之间的绝缘隔离，从而避免导电冷媒管10传输的信号受到干扰，同时，也可以避免导电冷媒管10传输的电力泄漏。
如图3和图4所示，安装座还设置有安装槽212，安装槽212与冷媒通道211连通，导电冷媒管10插设在安装槽212内。通过将导电冷媒管10插设在安装槽212内，可以使导电冷媒管10通过冷媒通道211与普通管路部件连通，从而实现冷媒的流通，同时还可以实现绝缘隔离。
如图3和图4所示，安装槽212的第一端与冷媒通道211相连，安装座在安装槽212的第二端位置处设置有导向面213。通过设置导向面213，可以在导电冷媒管10装配时，对导电冷媒管10进行导向，方便导电冷媒管10进入安装槽212，提高安装效率。
进一步地，安装座还设置有密封槽214，导电冷媒管10贯穿密封槽214，密封槽214与导电冷媒管10之间设置有密封件50。通过设置密封件50，可以有效起到密封作用，从而提高防水、防泄漏的效果。
需要说明的是，密封件50为密封圈或其他密封材料。
更进一步地，密封槽214与安装槽212之间连通，密封槽214与安装槽212之间通过导向面213相连。
如图5所示，接头还包括定位环60，定位环60的中心孔与导电冷媒管10过盈配合，定位环60位于密封件50与安装槽212之间，定位环60在导电冷媒管10取出时，带动密封件50同步脱出。通过设置定位环60，不仅可以启动对导电冷媒管10的定位作用，还可以在导电冷媒管10取出时，带动密封件50同步脱出，方便拆卸。
需要说明的是，如图5所示，定位环60中心孔位置处有多个向中心倾斜的弹性卡舌，弹性卡舌围成拟合的圆形，弹性卡舌设置的方向是沿着导电冷媒管10装配的方向设置的，在导电冷媒管10插入时，弹性卡舌稍稍扩张，使导电冷媒管10通过，而在导电冷媒管10取出时，弹性卡舌收缩，使定位环60卡在导电冷媒管10上，与导电冷媒管10一同移动，从而将密封件50一同带出。
还需要说明的是，定位环60具有用于引导导电冷媒管10穿过中心孔的引导面61。而弹性卡舌的表面就是引导面61，在导电冷媒管10插入时，可以通过引导面61将导电冷媒管10引向安装槽212，从而提高装配效率。
如图6所示，安装座21还包括压套22，压套22具有插接端221，插接端221插入至密封槽214内并挤压密封件50。通过设置压套22可以通过压套22将密封槽214 内的密封件50进行挤压，密封件50受到挤压后变形，使密封面扩大，从而进一步提高密封效果。
进一步地，压套22套设在导电冷媒管10外部，压套22与导电冷媒管10密封配合。可以起到防水、防泄漏的效果。
需要说明的是，在本实施例中，接头包括接口件30和锁紧件40，接口件30具有装配接口31，安装座连接在接口件30上；锁紧件40与接口件30可拆卸地连接，压套22穿设在锁紧件40上；锁紧件40在锁紧过程中，带动压套22挤压密封件50，同时，压套22将导电冷媒管10抵顶在安装座上。通过将压套22穿设在锁紧件40上，不仅可以实现对导电冷媒管10的绝缘隔离，还可以在装配过程中，将导电冷媒管10抵顶在安装座上，保证密封效果、提高可靠性和安全性。
还需要说明的是，压套22的外表面设置有凸筋222，锁紧件40在锁紧过程中与凸筋222抵顶配合并带动压套22。
接头还包括电缆70，电缆70具有用于与导电冷媒管10导电连接的连接端71，连接端71位于压套22内。部分电缆70埋设在压套22内，从而实现导电冷媒管10与电气部件之间的电连接。
进一步地，安装座21与接头和/或导电冷媒管10之间设置有密封结构，从而提高密封效果。
根据图未示出的实施例二，还公开了一种阀门，包括上述的接头。
根据图未示出的实施例三，公开了一种空调，包括上述的接头。
进一步地，空调包括室内机和室外机，室内机和室外机通过普通管路部件和导电冷媒管10连接，普通管路部件和导电冷媒管10连接在接头上。
显然，本公开的上述实施方式仅仅是为清楚地说明本公开所作的举例，而并非是对本公开的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无法对所有的实施方式予以穷举。凡是属于本公开的技术方案所引伸出的显而易见的变化或变动仍处于本公开的保护范围之列。
