具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
由于激光雷达或者激光测距仪等装置通常会在户外环境工作，而外界环境中的水汽如果进入装置内部，则可能在装置内的激光元件或者光学元件上凝结，造成雾面现象，影响到激光雷达等装置的正常工作。为了避免外界水汽的影响，激光雷达或者激光测距仪等装置会具有密封性较好的壳体，并利用壳体隔绝外界与装置内部。然而，激光雷达等装置在工作时需要依靠电连接线和外界之间传输电信号时，为了避免外界环境中的水汽通过电连接线进入激光雷达等装置的装置内部，激光雷达等装置的连接线也需要有较好的密封措施。
图1是本发明实施例一提供的一种连接线的结构示意图。图2是本发明实施例一提供的连接线中线缆本体的结构示意图。图3是图2中的线缆本体的截面示意图。如图1至图3所示，本实施例提供的连接线，所述连接线包括线缆本体1，线缆本体1包括外接端1a和内接端1b，线缆本体1的内接端1b用于连接在装置内部，外接端1a为远离内接端1b的另一端。线缆本体1的外接端1a可连接如接头2等外部元件，线缆本体1的内接端1a设置有第一密封胶层3，线缆本体1包括第一防护层11和被包裹在第一防护层11内的多根导线12，第一密封胶层3填充在导线12和第一防护层11之间的间隙中以及多根导线12之间的间隙中。
具体的，本实施例中的连接线，可以应用在激光雷达或者激光测距仪等装置。连接线一般包括有接头2和线缆本体1等组成部分，其中，线缆本体1的外接端用于和接头2连接，且接头2可以用于和该装置之外的其它装置的接口连接，而线缆本体1会伸入该装置的壳体内部，并与装置内部的信号端口以及电路保持电性连接。这样通过连接线的连接，即可实现 装置与外部设备的电性连接和信号传输。
而为了保证装置的密封性，一般在装置的壳体和连接线之间通常可以设置有密封结构，以避免外界水汽由连接线与壳体之间的间隙渗入。然而，接头2在与外界的设备连接时，外界水汽可能会由连接线的接头2进入连接线内部，进而进入装置内部。为了避免外界水汽的渗入，线缆本体1上设置有第一密封胶层3，第一密封胶层3位于线缆本体1的内接端，也就是线缆本体1的伸入装置内部的一端。
其中，连接线中的接头2可以为非防水接头，以简化连接线的结构以及降低连接线的制造成本。或者，连接线中的接头2也可以为防水接头，以提高连接线防水密封的可靠性。
具体的，线缆本体1包括有第一防护层11以及包裹在第一防护层11内的多根导线12。第一防护层11为绝缘层，且能够隔绝外界水汽，从而避免导线12受到外界环境的影响而产生短路等现象。不同导线之间会具有一定的间隙，此外，导线12和第一防护层11的内侧之间也会存在一定的间隙。当连接线的接头2为不具有防水密封功能的接头时，这些间隙会形成贯通整个线缆本体1长度方向的通道，外界的水汽就会通过上述间隙所形成的通道进入连接线的线缆本体1内部，并进而通过线缆本体1进入装置的内部。而将第一密封胶层3填充在第一防护层11和导线12之间的间隙，以及各个导线12之间的间隙中，此时，第一密封胶层3填满了位于第一防护层11和导线12之间以及各个导线12之间的间隙，让线缆本体1的外接端形成一个封闭端，从而起到阻隔水汽的作用。外界的水汽即使通过线缆本体1中各导线12以及导线12和第一防护层11之间的间隙流入，并抵达线缆本体1的内接端一侧，也会在线缆本体1的外接端受到第一密封胶层3的阻碍，无法通过并进入装置内部，因而使得连接线自身具有防水密封性，不会让外界水汽沿连接线进入装置内部，而装置内部的激光元件和光学元件可以始终处于干燥、密封的工作环境下，让装置能够正常进行工作；而和现有技术中采用防水接头进行防水密封的方式相比，采用密封胶构成的密封胶层对连接线内部的间隙进行密封，结构较为简单，成本较低，且制作工艺较为简易。其中，由于第一密封胶层3的设置，连接线的防水性能可以达到IPX7的防水等级。
其中，第一密封胶层3通常可以采用防水密封胶等粘接剂制成。具体的，由于防水密封胶等粘接剂在凝结前呈流动态，因而可以较为容易的通过灌注等方式进入第一防护层11和导线12之间的间隙，或者是各根导线12之间的间隙，并利用自身的流动性填充在这些间隙之间，待粘接剂凝结后，就可以将第一防护层11和导线12之间的间隙，以及各根导线12之间的间隙封闭起来，从而在线缆本体1的内接端形成能够阻隔外界水汽等杂质通过的封闭端，以避免水汽从上述间隙穿过。
具体的，为了让第一密封胶层3起到良好的密封性，构成第一密封胶层3的防水密封胶与第一防护层11以及线缆本体1中的导线12均应具有良好的粘接性能，从而让第一密封胶层3与第一防护层11和导线12均形成良好的接触，避免因第一密封胶层3和线缆本体1的其它部分粘接性能不足而产生影响线缆本体1气密性和防水性的空隙以及孔洞。
此时，需要说明的是，连接线中各根导线12之间可以具有一定的绝缘和防水性能，因而即使外界的微量水汽渗入连接线内部，也不会对连接线中正常的电信号传输造成影响。
具体的，线缆本体1中，被包裹在第一防护层11内的导线12，既可以是直接用于传输电信号的线芯，也可以是外部包裹有绝缘保护材料的独立芯体。以下分别具体进行详细说明。
在一种可选的方式中，被包裹在第一防护层11内的各导线12可以直接为用于传输电信号的线芯。此时，线芯可以是一根，也可以由多根线材缠绕成线束状，而各个线芯可以独立或者缠绕成直径较大的线束，从而完成不同的信号传输功能。
图4是本发明实施例一提供的连接线中另一种线缆本体的结构示意图。图5是图4中的线缆本体的截面示意图。如图4和图5所示，在另一种可选的方式中，线缆本体1中的导线12具体可以包括芯体121和包裹在芯体121外侧的第二防护层122，第二防护层122和芯体121之间的间隙中填充有第二密封胶层4。
具体的，线缆本体1中的每根导线12均可以为独立的芯体121，因而当线缆本体1中所包括的多根导线12可以分别用于传输不同的信号，以完成较为复杂的信号传输功能。为了避免不同导线12上的信号之间发生 相互干扰，每根导线12的芯体121外侧均包裹有第二防护层122，和第一防护层11类似，第二防护层122也由绝缘材料构成，并能够隔绝外界水汽，因而可以在芯体121与外界之间起到绝缘保护作用，避免芯体121与外界导通，而发生信号干扰甚至是短路等现象。这样每根导线12即可用于传输和其它导线12不同的电信号。具体的，第一防护层11和第二防护层122可以由聚氯乙烯(Polyvinyl chloride，PVC)或者其它常见的绝缘塑料等材料制成。
由于每根导线12均包括芯体121以及包裹在芯体121外侧的第二防护层122，因而和第一防护层11类似，在第二防护层122和芯体121之间也会具有一定的间隙，而这些间隙也会形成可容水汽通过的通道。如果外界水汽从连接线的接头2进入线缆本体1，则可能会沿着第二防护层122和芯体121之间的间隙一直前进，并由线缆本体1的内接端进入装置内部。
因而，为了避免水汽对装置内部的元件工作造成影响，在第二防护层122和芯体121之间可以设有第二密封胶层4，第二密封胶层4填充在第二防护层122和芯体121之间的间隙中，因而可以填满该间隙，并将该间隙封闭起来。此时，如果有水汽进入第二防护层122与芯体121之间的间隙中，并抵达第二密封胶层4所处的位置时，即可被第二密封胶层4所阻挡而无法继续前进，这样水汽也就无法进入装置的内部，起到了防水密封作用。
这样当导线12为包括有芯体121及第二防护层122的独立导线12时，通过在芯体121和第二防护层122之间的间隙中填充第二密封胶层4，可以封闭导线12内部的间隙，进一步提高连接线对于外界水汽的防护密封效果。
其中，和第一密封胶层3类似，第二密封胶层4也可以设置在线缆本体1的内接端，使得线缆本体1的内接端形成封闭端，阻碍水汽的进入。这样将第一密封胶层3和第二密封胶层4均设置在线缆本体1的端部位置，便于第一密封胶层3以及第二密封胶层4的填充，可以降低连接线的制作难度，并有利于提高密封胶层的密封防水效果。
同样的，和第一密封胶层3类似，第二密封胶层4也可以采用防水密封胶等粘接剂制成。具体可以将在凝结前呈流动态的防水密封胶灌注在芯 体121和第二防护层122之间，并利用防水密封胶的流动性，使其填充满这些间隙，待粘接剂凝结后，就可以将芯体121和第二防护层122之间的间隙封闭完成。
为了保证信号的传输质量，作为一种可选的结构，在连接线的线缆本体1中，每根导线12中可以包括多根芯体121。这样多根芯体121可以共同传输信号，从而减低连接线的阻抗，提高信号的传输质量和信号强度，并避免单根芯体121断裂而造成信号无法传输的情况发生。
具体的，每根导线12中的各根芯体121均可以为单根线材。一般的，芯体121可以为金属线材构成，例如可以是利用铜线构成导线12的芯体121，此时，导线12中的芯体121可以为铜绞线。
然而，当每根导线12中包括有多根芯体121时，不同芯体121之间同样会存在有一定的间隙。这样当连接线的接头2处进水时，外界的水汽可能会进入单根导线12中各根芯体121之间的间隙内，并沿着这些间隙所形成的通道穿过整根连接线，最终进入装置内部。为了避免外界水汽经由单根导线12内各芯体121之间的间隙进入装置内部，需要对单根导线12的各芯体121之间进行密封处理，以消除各个芯体121之间的间隙。
图6是本发明实施例一提供的连接线中第三种线缆本体的结构示意图。如图1和图6所示，作为一种可选的实施方式，可以让每根导线12中的多根芯体121之间通过可导电的熔融物密封。此时，熔融物可以在熔融态下伸入各芯体121之间的间隙，并与芯体121表面形成良好的接触，这样各芯体121之间的间隙就能够被熔融物所填满，从而让熔融物和芯体121共同连结在一起，并构成一个能够密封防水的封闭端。
其中，熔融物为可导电的材料形成，因而熔融物自身不会影响到芯体121的正常导电性能，从而可保证信号的良好传输。一般的，熔融物可以为熔点较低的金属，这样可以通过对进入加温让金属呈流动态，金属流入导线12各芯体121之间的间隙，并填满这些间隙之后，再让金属冷却凝固，金属即可将各芯体121连结在一起，从而让导线12内各芯体121在金属熔融的位置构成统一的整体，从而避免外界水汽从金属熔融凝结的部位通过。
具体的，作为其中一种可选的方式，每根导线12中的多根芯体121 之间可以通过镀锡密封。其中，锡具有较低的熔点和良好的导电性，因而让各根芯体121之间通过镀锡而连接并密封在一起，能够较好的填充并消除各根芯体121之间的间隙，完成导线12内部的密封。
进一步的，由于只要让导线12的端部进行密封，即可让导线12具有良好的气密性和防水密封性能，因而在对导线12中各芯体121进行镀锡时，芯体121的镀锡部位可以为芯体121的端部。此时，每根导线12中各个芯体121的端部上共同镀有一层锡层123。这样在芯体121的端部进行镀锡操作，让导线12中各芯体121的端部镀上锡层123，芯体121的端部就可以在镀锡作用下完成密封。
此时，为了让熔融态的锡填充芯体121之间的间隙，可以将连接线中各导线12的第二防护层122端部剥开，以将芯体121的端部部位裸露在外，此时，外侧去除了第二防护层122的芯体121端部即可较为方便的完成镀锡操作。这样在镀锡时便于进行操作，能够降低连接线的制作难度，减少生产成本。
其中，在利用镀锡的方式完成导线12中多根芯体121之间的密封时，为了保证密封性能，可选的，芯体121端部的镀锡长度可以为4-6mm，且一般在5mm左右。此时，芯体121上的镀锡长度较为适中，一方面能够保证镀锡能够填充在各芯体121之间的间隙中，以实现良好的防水密封性能；另一方面，镀锡长度在4-6mm之间，便于完成镀锡工序的操作，并减少镀锡量，有效的降低连接线的生产成本。
而同样的，在利用第一密封胶层3以及第二密封胶层4完成连接线的防水密封时，也可以将第一密封胶层3和第二密封胶层4设置在连接线的不同特定位置，以下进行具体说明。
可选的，为了便于设置第一密封层，导线12的内接端端部可以延伸至第一防护层11的内接端端部之外。此时，导线12从第一防护层11的内接端端部中露出，并向外伸出一定距离，这样即可方便在导线12和第一防护层11之间设置第一密封胶层3。具体的，可以通过去除第一防护层11内接端端部的部分，以使导线12从中露出。
此时，作为一种可选的方式，可以将第一密封胶层3设置在第一防护层11的内接端端部与导线12之间的间隙中。此时，第一防护层11的内 接端端部与导线12的外表面之间具有环形的间隙，而第一密封胶层3即可密封在第一防护层11的端部与导线12之间，从而封闭该环形的间隙，使第一防护层11的内接端端部形成一个密封端，防止水汽从第一防护层11与导线12之间的间隙中渗出。这样将第一密封胶层3设置在该处，一方面有利于第一密封胶层3的定位，使第一密封胶层3能够形成良好的密封效果，另一方面也可以减少第一密封胶层3中密封胶的用量，减少生产成本。
而类似的，作为一种可选的实施方式，每根导线12中，芯体121的内接端端部可以位于第二防护层122的内接端端部之外。具体的，芯体121可以从第二防护层122的内接端端部中露出，并向外伸出一定距离，这样即可方便在第二防护层122与芯体121之间设置第二密封胶层4。
其中，和第一防护层11类似，让芯体121从第二防护层122中露出时，具体可以通过去除第二防护层122内接端端部的部分，以使导线12的芯体121从中露出。
相应的，在可选的方式中，第二密封胶层4设置在第二防护层122的内接端端部和芯体121之间的间隙中。这样第二密封胶层4即可密封在第二防护层122的端部与芯体121之间的环形间隙中，从而封闭该环形的间隙，使第二防护层122的内接端端部形成一个密封端，防止水汽从中渗出。这样设置第二密封胶层4，其好处和第一防护层11类似，一方面有利于第二密封胶层4的定位，使第二密封胶层4能够形成良好的密封效果，另一方面也可以减少第二密封胶层4中密封胶的用量，减少生产成本。
此外，图7是本发明实施例一提供的连接线中第四种线缆本体的结构示意图。如图1和图7所示，为了简化密封胶的设置工序，作为一种可选的方式，在线缆本体中，也可以让第一密封胶层3与第二密封胶层4延伸并呈一体。这样第一密封胶层3设置在第一防护层11和导线12之间，而第二密封胶层4设置在第二防护层122和芯体121之间，且第一密封胶层3和第二密封胶层4相互连接以形成一体结构，从而可以将防水密封胶同时或者分批灌注至连接线上的各个相应部位，并让用于密封不同间隙的第一密封胶层3和第二密封胶层4之间连接成一体式结构，从而提升密封性能，并简化设置第一密封胶层3和第二密封胶层4的工序。
本实施例中，连接线具体包括线缆本体和接头，线缆本体的外接端用于和接头连接，线缆本体的内接端用于连接在装置内部，线缆本体的内接端设置有第一密封胶层，线缆本体包括第一防护层和被包裹在第一防护层内的多根导线，第一密封胶层填充在导线和第一防护层之间的间隙中以及多根导线之间的间隙中。这样连接线内部的间隙能够被密封胶层所填满和封闭，从而避免外界水汽由连接线进入装置内部，具有较好的气密性和防水性能，且成本较低。
图8是本发明实施例二提供的一种光学测量装置的结构示意图。如图8所示，本实施例中的光学测量装置200，具体包括壳体101、测量单元102和前述实施例一述的连接线100，测量单元102密封设置在壳体101内，且测量单元102包括电接口1021和光学元件1022，连接线100的内接端伸入壳体101内并与电接口1021连接。其中，连接线100包括接头2和线缆本体1，线缆本体1的外接端和接头2连接，线缆本体1的内接端用于连接在光学测量装置200的内部，线缆本体1的内接端设置有第一密封胶层，线缆本体1包括第一防护层和被包裹在第一防护层内的多根导线，第一密封胶层填充在导线和第一防护层之间的间隙中以及多根导线之间的间隙中。连接线100的具体结构、功能以及工作原理均已在前述实施例一中进行了详细说明，此处不再赘述。
具体的，光学测量装置200包括壳体101，壳体101可以将内部的测量单元102等部件保护在其中，从而让光学测量装置200能够在较为恶劣的户外环境中使用，以避免外界的水汽等影响到光学测量装置200的正常工作。
此外，光学测量装置200中还具有测量单元102，测量单元102可以包括用于进行光学测量的光学元件1022，以及用于控制和电信号传输的电接口1021等。光学元件1022可以包括有各类不同的光学镜片，并通过光线的折射或反射完成光学测量任务。而测量单元102中还可以包括有电接口1021，电接口1021可以用于产生或传输电信号，让测量单元102完成正常的测量工作。而连接线100即可连接光学测量装置200的电接口1021以及外部的其它装置或设备，以传输光学测量装置200所测量的信号或者对光学测量装置200进行控制。其中可选的，光学测量装置200可以为激 光雷达或者激光测距仪等既包括光学元件，也包括电气元件的测量装置。
而为了保证光学测量装置200的密封性，可选的，光学测量装置200的壳体101和连接线100之间通常设置有密封结构，从而实现密封连接，以避免外界水汽由连接线100与壳体101之间的间隙渗入。
具体的，当光学测量装置200为激光雷达或者激光测距仪等时，可选的，连接线100内部可以设置有12根导线，并利用这12根导线分别实现不同的功能或者是进行不同的信号传输。
本实施例中的光学测量装置200中，由于连接线100内部被密封胶层所封闭，所以外界的水汽无法通过连接线100内部的间隙进入光学测量装置200内部，让光学测量装置200内部的光学元件1022不会受到水汽影响而产生起雾等现象，有效的保证了光学测量装置200的正常工作。
本实施例中，光学测量装置具体包括壳体、测量单元和连接线，测量单元密封设置在壳体内，且测量单元包括电接口和光学元件，连接线的内接端伸入壳体内并与电接口连接；其中，连接线包括接头和线缆本体，线缆本体的外接端和接头连接，线缆本体的内接端用于连接在光学测量装置的内部，线缆本体的内接端设置有第一密封胶层，线缆本体包括第一防护层和被包裹在第一防护层内的多根导线，第一密封胶层填充在导线和第一防护层之间的间隙中以及多根导线之间的间隙中。这样连接线内部的间隙能够被密封胶层所填满和封闭，从而避免外界水汽由连接线进入光学测量装置内部，具有较好的气密性和防水性能，让光学测量装置在户外环境中也能够正常工作，且成本较为低廉。
