Description

一种抗拉连接器 技术领域
本申请涉及连接器技术领域，具体涉及一种抗拉连接器。
背景技术
在电缆光纤的连接和铺设工作中，通常使用连接器来将电缆和终端或电缆之间进行连接，实现光电信号的导通。连接器还常作为信号传输的连接件来进行线路转接或线路导通。为防止连接器在连接后的使用过程中，线缆遭到人为拉扯或外力牵引使线缆向外拉伸，进而导致连接器中连接位置处的光纤或导线被拉断，因此连接器内部常设置有抗拉部件，提高连接器的抗拉性。
现有技术中的连接器的结构如图1所示，其包括外壳1以及设于外壳1前端的内芯组件，内芯组件包括内芯壳体和设于内芯壳体上的内芯插头5，内芯插头5的后端连接有线缆7，为防止线缆7受外力而被牵拉，连接器还包括压接在线缆7上的堵头2、堵头2上的压紧圈3，以及转动安装在外壳尾部的螺母4，当螺母向前旋转时能够径向压紧堵头，从而将线缆压紧实现抗拉。这种连接器的抗拉力通常较小(低于100N)，而为了增大连接器的抗拉力，需在堵头处增加相应的固定器。如图2所示，在线缆的外部设置固定器7，此处的固定器7通常是由胶体形成，通过固定器7与堵头2的前后挡止来增大抗拉力，当然，在实际使用时也可以将固定器7更换为热缩管。现有技术中的连接器在使用的过程中，存在的问题在于，线缆的前端与内芯组件之间为直接固定相连的装配关系，由于线缆不易被折弯，内芯插头在使用时无法相对于外壳前后移动，但是在实际使用过程中，有时需要内芯插头可以相对于外壳前后浮动，以满足使用和装配的要求。

本实用新型所提供的抗拉连接器的具体实施例1：
如图3至图5所示，抗拉连接器包括外壳1、内芯组件9、抗拉部件29以及线缆6。其中，定义外壳1用来对插的一端为前端，内芯组件9设置于外壳1的前端，内芯组件9的后端连接装配抗拉部件29，内芯组件9通过抗拉部件29和线缆连接。内芯组件9包括内芯壳体，还包括设置在内芯壳体前端的内芯插头5。在外壳1内部后端设置堵头2，堵头2通过外壳1后端旋拧的螺母4将线缆压紧，在螺母4和堵头2之间还设有压紧圈3。线缆6为外部由绝缘外皮包裹、中间为绝缘体阻隔、内部为缆芯的结构。在抗拉部件29上还设有与线缆6相连接的凸台25，凸台25和线缆6连接后，在其连接位置上套装压接套8，通过压接套8的径向变形来固定凸台25和线缆6。其中，压接套8压接后，凸台25和线缆6的绝缘外皮和绝缘体相连，线缆6内部的缆芯穿过压接套8和凸台25，延伸至内芯壳体中与内芯插头5相连接，从而实现电路信号的导通。在外壳1的内部上设有挡止部26，通过外壳1上的挡止部26与抗拉部件29的配合挡止，防止线缆6被向后牵拉，从而实现抗拉部件29的抗拉效果。
如图6至图8所示，内芯壳体包括底座11和盖板10，底座11为上端开口的C形结构座体，底座11的底壁上设有T形的导槽27，在底座11尾端还对称地设置有底座挡止凸台15，其中，两个挡止凸台15位于底座11的内部，抗拉部件29通过导槽27滑动装配在底座11中并与底座挡止凸台15挡 止，以实现底座11的前后浮动，并且防止抗拉部件29相对于底座11向后脱出。
具体地，抗拉部件29包括连接套12、支撑套13以及固定套14，如图6和图9所示，连接套12的中心位置有孔，供线缆的缆芯穿过。连接套12的底部设有导向体28，其中，导向体28的形状与导槽27相同，能够与导槽27相对滑动，从而实现前后滑动在底座11中。在连接套12的前端朝两侧凸出设置有连接套挡止凸台30，连接套挡止凸台30与底座挡止凸台15进行前后挡止，从而防止连接套12朝后脱出底座11。在连接套12的后端端面上相对称地一体加工有两个弹爪17，弹爪17具有一定的弹性摆动量，弹爪17具有分置于两侧的钩部16。在两个弹爪17的周向间隔位置处还设置有导柱18，两个导柱18对称布置。
连接套13的结构如图10所示，连接套13中心有孔，供线缆的缆芯穿过。支撑套13包括和连接套12对接的支撑台，在支撑台另一端设置凸台25。在支撑套13的支撑台侧面上开设支撑套卡槽19，支撑套卡槽19的设置位置与连接套12上弹爪17的位置相对应，使支撑套13能够卡装在连接套12的弹爪17内侧钩部16中。在支撑台上还设有与连接套12上的导柱18位置对应的引导孔20，在连接装配时利用导柱18及引导孔20进行预定位。如图7所示，通过导柱18插入引导孔20以及安装槽卡装在弹爪17内侧钩部16中，使连接套12和支撑套13间连接紧固。
固定套14的结构如图11所示，固定套14为一侧开口的C形结构，固定套14具有能够套装支撑套13的内孔，在固定套14内孔的内壁上设置有卡板21，卡板21的朝向固定套14中心的一侧设有固定套卡槽24。卡板21的设置位置和固定套卡槽24的开设位置与支撑套13外部卡装的连接套12的弹爪17相对应，使卡板21上的固定套卡槽24能够与连接套12弹爪17的外侧钩部16相卡装，从而完成固定套14、支撑套13和连接套12的卡接固定。为保证安装时弹爪17能在固定套卡槽24中回弹调整，预防弹爪17在固定套14内孔中卡死的情况，在卡板21和固定套14内壁间还开设有通槽23，使固定套卡槽24能够向外变形，便于弹爪17的弹出和调整。在固定套14的内孔一端还设有限位台22，限位台22与支撑套13相挡止，使支撑套13受到线缆6牵拉力时，将力经限位台22传导至固定套14上。
固定套14装配完成之后，固定套14的后端端面与壳体1内的挡止部26前后挡止，因此抗拉部件29在外壳1中固定不动，而连接套12滑动装配在 底座11中，因此内芯插头5的前后浮动实际上是底座11在连接套12外的前后滑动。本实施例中的连接套12、支撑套13以及固定套14为分体设置的零部件，各部件分体固设构成抗拉部件29。
本实施例中，固定套14的后端端面形成了抗拉部件的挡止部26。
本实用新型所提供的抗拉连接器的具体实施例2：
与实施例1的不同之处在于，实施例1中，连接套12、支撑套13以及固定套14为分体固设的不同零部件，三个部件互相配合连接构成了抗拉部件29。在本实施例中，如图12和图13所示，抗拉部件29为一体加工成形，此时线缆6连接后无法从连接器中拆分。在其他实施例中，连接套、支撑套和固定套还可以两两加工为一体，与另一个分体固连，节省加工成本。
本实用新型所提供的抗拉连接器的具体实施例3：
与实施例1的不同之处在于，实施例1中，内芯壳体的底座11为一侧开口的C形结构，底座11的底壁上设有与连接套12导向配合的导槽27，在连接套12底部设置和导槽27导向配合的导向体28，且导槽27为T形槽。在本实施例中，将导槽更换为等宽槽，此时的导槽仅起到对底座、连接套相对移动的导向作用，而不具备防止连接套朝底座开口方向脱出的作用。在其他实施例中，取消导槽及导向体的设置，连接套直接在底座中滑动装配。在其他不同的实施例中，内芯壳体一体成型，不可拆分，增加了内芯壳体的密封性。
本实用新型所提供的抗拉连接器的具体实施例4：
与实施例1的不同之处在于，实施例1中，抗拉部件29包括位于支撑套13后端的凸台25，凸台25和线缆6连接位置设有压接套8，通过压接套8的径向变形来固定凸台25和线缆6。在本实施例中，压接套可替换为热缩管。
本实用新型所提供的抗拉连接器的具体实施例5：
与实施例1的不同之处在于，实施例1中，连接套12上设有两个对称的导柱18，支撑套13上设有与导柱18对应的引导孔20。在本实施例中，导柱和引导孔的位置可进行对调，即导柱设置在支撑套上，引导孔设置在连接套上。在其他实施例中，导柱和引导孔的设置数量也可根据定位的需求进行增减。在其他不同的实施例中，取消导柱和引导孔的设置。
本实用新型所提供的抗拉连接器的具体实施例6：
与实施例1的不同之处在于，实施例1中，固定套14为一侧开口的C形结构，固定套14中卡装支撑套13的内孔一端设有限位台22，限位台22将支撑套13在固定套14中轴向挡止。在本实施例中，取消限位台。在其他实施例中，固定套还可加工为周向封闭的环形结构。
本实用新型所提供的抗拉连接器的具体实施例7：
与实施例1的不同之处在于，实施例1中，连接套12后端设有弹爪17，弹爪17具有分置于两侧的钩部16，支撑套13和固定套14上都设有与弹爪17的钩部16相适配对应的卡槽。其中，固定套14的卡槽设置在固定套14内壁上的卡板21上。在卡板21和内壁间还设有通槽23。本实施例中，固定套直接螺纹装配在支撑套的外部。其他实施例中，固定套、连接套和支撑套的固定方式可以进行改变，比如可以为粘接或焊接等。
本实用新型所提供的抗拉连接器的具体实施例8：
与实施例1的不同之处在于，实施例1中，抗拉部件29由支撑套13、固定套14以及连接套12组成。在本实施例中，抗拉部件的形状可以进行改变，比如取消支撑套外部的固定套，仅在支撑套的外周面上设置朝后凸出布置的挡块来形成抗拉部件的挡止部。
最后需要说明的是，以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型，尽管参照前述实施例对本实用新型进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行不需付出创造性劳动的修改，或者对其中部分技术特征进行等同替换。凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
