These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
参照图1和图13所示,本实施例提供了一种电力电缆终端,包括:电缆连接组件和终端衔接套。其中电缆连接组件包括固定电缆A一端去皮后的部分的导体连接套,以及适于与导体连接套配接的导体连接件,在对电缆A进行装配的过程中,对电缆A的一端剥除外皮,再将去除外皮的电缆A与导体连接套配接固定。终端衔接套包括适于与导体连接套配接的公端21,以及适于出线导体B配接的母端22,此处的出线导体B可通过一个插接头39与母端22配接,该母端22与插接头39之间可通过螺纹配接相连。Referring to FIG. 1 and FIG. 13 , this embodiment provides a power cable terminal, including: a cable connection assembly and a terminal connection sleeve. The cable connection assembly includes a conductor connection sleeve for fixing the peeled part of one end of the cable A, and a conductor connection piece suitable for mating with the conductor connection sleeve. In the process of assembling the cable A, one end of the cable A is stripped except Remove the sheath, and then mate and fix the cable A with the sheath removed with the conductor connection sleeve. The terminal connection sleeve includes a
更为详细的,本实施例的导体连接件包括环形连接套1、在环形连接套1上设有的至少一对凹陷槽2,以及与至少一对所述凹陷槽2装配相连的至少一对锁扣。结合本实施例附图,以在环形连接套1上对称设有一对即两个凹陷槽2以及与一对凹陷槽2装配相连的一对锁扣的情况为例。此处的环形连接套1采用例如但不限于金属铜材质制成。In more detail, the conductor connector of this embodiment includes an
具体的,本实施例的环形连接套1沿其轴向贯通有中心空腔3;一对凹陷槽2间隔地凹陷成型在环形连接套1的外壁上;需要说明的是,此处的凹陷槽2与中心空腔3并不连通。一对锁扣一一对应地嵌设在凹陷槽2中;锁扣包括适于装嵌在凹陷槽2中的装配部8,以及与装配部8相连的锁钩。Specifically, the annular connecting
此外,还需要说明的是,在环形连接套1的侧壁上还开设有适于锁钩贯穿后伸出至中心空腔3中的缺槽5。在凹陷槽2中还开设有与缺槽5连通以适于锁钩穿过的缺口7。也就是说缺口7与缺槽5连通使得锁钩可以部分地逐渐伸入至中心空腔3中,并且在锁钩活动的过程中,锁钩的运动轨迹不会受到装配部8与凹陷槽2配接的限制。In addition, it should be noted that the side wall of the annular connecting
考虑到锁钩由环形连接套1的外壁向中心空腔3运动的过程中,装配部8可以随着锁钩同步运动而又不会脱离凹陷槽2,本实施例的装配部8采用圆柱状体结构;以及凹陷槽2的截面为弧形状结构。需要说明的是,装配部8与凹陷槽2过盈配合,且装配部8适于在凹陷槽2中转动。过盈配合的情况,使得装配部8随着锁钩运动的过程中不会出现装配部8从凹陷槽2中脱离的情况,而且装配部8还可以在凹陷槽2中转动,此处只需要对锁钩施加一定的拨动作用力,即可通过拨动锁钩的情况下使得锁钩和装配部8一起运动。Considering that during the movement of the lock hook from the outer wall of the annular connecting
更为详细的来说,本实施例的锁钩包括与装配部8相连的连接部9,以及与连接部9远离装配部8的一端弯折相连的凸钩10;凸钩10相对于连接部9凸起以使得凸钩10与连接部9呈L形结构。且此处还需要加以说明的是,凸钩10相对于连接部9朝向中心空腔3一侧弯折。这样设计的意义在于当本实施例的导体连接件应用在电力电缆A连接结构中时当中心空腔3与其它结构配接后,凸钩10可与其它结构有效的配接。In more detail, the locking hook of this embodiment includes a connecting
可选的一种实施情况下,凸钩10朝向中心空腔3的侧端面为弧形面,此处的弧形面主要是为了与本实施例的导体连接件应用在电力电缆A连接结构中时与其它部件保持良好的配合接触效果。In an optional implementation, the side end surface of the
再进一步来说,本实施例的导体连接套包括本体11以及与本体11一体相连的适于嵌入至导体连接件中的中心空腔3内的止退轴12。公端21与本体11的外壁套接固定,此处的本体11可与公端21之间采用螺纹配接的方式来实现两者的连接。Still further, the conductor connection sleeve of this embodiment includes a
再具体来说,在止退轴12的周向侧壁凸设有适于一一对应与一对锁扣契合相配接的一对凸台13。详细的,锁扣的凸钩10适于与凸台13朝向导体连接套的端面卡嵌配接。More specifically, a pair of
也就是说在导体连接件与导体连接套配接的过程中,止退轴12插入至导体连接件的中心空腔3中,再拨动锁钩,使得锁钩的凸钩10沿着缺槽5伸入至中心空腔3中,最终使得凸钩10可以与凸台13契合相配接,此时,通过凸钩10与凸台13的配合使得止退轴12不会从中心空腔3中脱离,如此即实现了导体连接套与导体连接件的配接相连。That is to say, during the mating process of the conductor connector and the conductor connector sleeve, the
本实施例的电缆连接组件还包括套接在电缆A靠近导体连接套的部分的外皮上的应力锥23,以及与应力锥23远离导体连接套的一端相接的锥托总成;其中锥托总成包括与应力锥23相地接的承托部25、与承托部25相抵接的若干个压缩弹簧26,以及与若干个压缩弹簧26远离承托部25的一端相抵接的底托27。此处还需要辅助说明的是,在电缆A的外皮上还通过环氧树脂材料一体注塑有接头套28,应力锥23朝向导体连接套的一端与接头套28抵接。The cable connection assembly of this embodiment also includes a
还需要加以说明的是,承托部25和底托27上开设有与压缩弹簧26的内孔贯通的连接孔;以及分别位于承托部25和底托27上的连接孔适于压紧螺栓29穿过以实现底托27、压缩弹簧26与承托部25之间的压紧配接。如此,在压缩弹簧26的弹性作用下,可以使得应力锥23与接头套28之间保持压紧的效果。It should also be noted that the supporting
此外,本实施例的电力电缆终端还包括与压紧螺栓29相抵的且套装在电缆A外皮上的法兰30;法兰30通过螺钉与底托27配接相连;以及法兰30远离底托27的一端配接的且套装在电缆A外皮上的金属屏蔽连接环31。In addition, the power cable terminal of this embodiment also includes a flange 30 that is against the pressing bolt 29 and is sleeved on the outer skin of the cable A; the flange 30 is connected to the bottom bracket 27 through screws; and the flange 30 is far away from the bottom bracket One end of 27 is matched with a metal
另外,电力电缆终端还包括一外套管32,以及与外套管32轴向两端分别配接的顶盖33和底盖35;其中出线导体B远离终端衔接套的一端穿过顶盖33;以及电缆A远离导体连接套的一端穿过底盖35。本实施例的外套管32形成对于整体的电力电缆终端结构的外部保护。In addition, the power cable terminal also includes an
此外,本实施例的底盖35与外套管32之间还配接有一锥托保护罩,锥托保护罩包括呈L形结构的纵向部36和横向部38,该纵向部36包套在外套管32的外壁上,且纵向部36还通过螺钉与底盖35配接,而横向部38则是通过螺钉与法兰30配接固定。In addition, the
