Description

一种熔断器底座接线端子的连接组件 技术领域
本发明涉及熔断器底座，尤其涉及一种熔断器底座中的接线端子的连接组件。
背景技术

因此，有必要设计一种供用户自由选择的熔断器底座接线端子的连接组件。
发明内容
本发明的目的在于克服现有技术的不足，提供一种供客户自由选择的熔断器底座接线端子的连接组件。

具体实施方式
下面结合附图来进一步说明本发明的具体实施方式。
如图2所示，熔断器底座接线端子的连接组件，包括底座1和设置在底座1中的接线端子2，接线端子2上设有连接孔21，还包括与接线端子2插接的支持件3，支持件3包括用于收容螺母4或螺栓5的收容槽31，收容槽31的侧面设有开口32，收容槽31的底部设有通孔37，底座1上与支持件3对应的位置设有螺栓安装孔11，螺栓安装孔11、连接孔21与通孔37三者位于同一轴线上。图2为支持件3与接线端子2插接后的状态。图3为支持件3与接线端子2分离的状态。
当用户需要螺母接线端子时，首先将支持件3从接线端子2上拔出。然后，如图5所示，将螺母4放入支持件3中。最后，将支持件3连同螺母4一起推入接线端子2。螺母4可以沿图5中的垂直方向插入到收容槽31中，也可以沿图5中的水平方向通过开口32进入到收容槽31中。
当用户需要螺栓接线端子时，首先将支持件3从接线端子2上拔出。然后，如图6所示，将螺栓5从底座1的螺栓安装孔11插入，再插入到接线端子2的连接孔21中。最后，将支持件3推入接线端子2，固定螺栓5。推入支持件3时，螺栓5的头部通过开口32，进入到收容槽31中。
由于设有与接线端子可插接的支持件，支持件中可以放入螺母或螺栓。用户可以自由选择在支持件中放入螺母或螺栓，来实现接线端子与线缆的连接。支持件起到了收容螺母或螺栓，并将螺母或螺栓固定到接线端子的作用。
本实施例中，如图4所示，支持件3的底部设有通孔37。当支持件3的收容槽31用于收容螺母时，连接电缆用的螺栓依次通过连接孔21、螺母4与通孔37，将电缆锁紧在接线端子2上。
本实施例中，如图4所示，收容槽31为六边形。收容槽31的形状与螺母4和螺栓5的头部形状相同，并略大于螺母4和螺栓5的头部。六边形的收容槽31能够起到防止螺母和螺栓在收容槽中发生窜动的作用。
较佳地，收容槽也可以为其他形状，只要能够起到收容螺母和螺栓 的作用都属于本发明的保护范围。
本实施例中，如图4所示，六边形的收容槽31的开口32的宽度大于收容槽31的相邻两侧面的宽度。开口32方便螺母4和螺栓5收容到收容槽32中。尤其是对于螺栓5来说，当螺栓5插入到接线端子2上后，由于开设了开口32，并且开口32的宽度大于六边形的收容槽32的两个侧面的宽度，螺栓5的头部能够顺利通过开口32，这样支持件3能够沿图6的水平方向插入到接线端子2上。
本实施例中，如图4所示，开口32的底部设有限位凸台33。限位凸台33的高度高于收容槽31的底部，限位凸台33用于限制放入到收容槽31中的螺母4位置，防止螺母4从收容槽31中滑出。而螺栓5由于插入到连接孔21中，通过连接孔21来限定位置，因此不需要限位凸台33的限位。
本实施例中，如图4所示，支持件3上对称设置有两个凸耳34，凸耳34与收容槽32之间形成沉台35，沉台35用于与接线端子2卡接。如图2所示，支持件3与接线端子2插接后，沉台35与接线端子2的底面接触，凸耳34位于接线端子2的两侧。沉台35能够起到防止支持件3翻转的作用。
较佳地，如图4所示，凸耳34包括止档部341，止档部341用于限定支持件3插入接线端子2的位置。接线端子2上形成有与止档部341配合的缺口部22(参见图3)，止档部341卡入缺口部22中。
本实施例中，如图4所示，支持件3还包括弹性卡钩36，弹性卡钩36用于连接接线端子2对应位置的底座1。本实施例中弹性卡钩36形成在开口32的两侧。较佳地，弹性卡钩36也可以形成在支持件3的两侧，或其他位置，只要能够起到与底座1连接用于固定支持件3的作用，都属于本发明的保护范围。
以上所述的仅是本发明的原理和较佳的实施例。应当指出，对于本领域的普通技术人员来说，在本发明原理的基础上，还可以做出若干其它变型，也应视为本发明的保护范围。
