Description

防止连接螺栓自身旋入 的保险装置
本发明涉及一种防止连接螺栓自身旋入的保险装置。
在向客户发送一种电器(例如继电器)时，连接件通常松开，即连接螺栓通常旋出。由于运输过程中的震动或振动，连接螺栓可能自身旋入。应该防止这种自身旋入。
至今公知的防旋入保险装置中，通过摩擦来提高旋入扭矩。为此例如设置筋片。这样，螺纹切入这些筋片，或者这些筋片在螺栓头上摩擦。另一种方法是采用弹性凸缘，它们被夹在螺纹和螺纹插座之间。在另一种解决方式中，采用定位结构来固定螺栓头。再一种可能性是“听之任之(ueberKopf)”地运输仪器，从而震动或振动起到旋出螺栓的作用。
如果由一个接触块和连接螺栓组成的完整连接件，以旋入螺栓的装配方式***一个连接机架，那么夹在螺纹和连接螺栓的插孔之间的凸缘会脱出。这种情况仅仅在安装接触块或连接块和将连接螺栓沿旋入方向***之后才可能发生。
让螺纹切入的筋片并不适宜，因为螺纹在第一次旋出时就已切入筋片，随后旋入扭矩不再以必需的量度提高。此外，一种带有栓颈的连接螺栓在螺纹碰到可能在螺纹杆(Gewindedurchzugs)之下才伸展的筋片之前可能旋入得比较深。
只有采用不绝缘的螺丝刀来旋入或旋出螺栓时，才可能为在比较深地处于电器的防护罩内的连接螺栓设置在螺栓头上摩擦的筋片和定位结构(它承接螺栓头)，因为筋片或定位结构大大缩小用于螺丝刀的空隙。
本发明的目的在于提供一种上述类型的防止旋入的保险装置，它在连接螺栓处于旋出状态时可靠地防止螺栓自身旋入，同时它使得***由接触块和连接螺栓组成的完整连接件成为可能，而且在旋出螺栓时它并不损伤连接螺栓。
本发明的目的是这样实现的，即，设置由两个弹性撑筋组成的叉形托架。调整该托架，使得在它的空隙内居中容纳连接螺栓。
这么有利地构造该托架，即，在组装一个由连接螺栓和一个连接块组成的完整连接件时，使该托架象剪刀一样张开。
此外有利的是：两个撑筋的间距小于连接螺栓的螺纹根直径或一个有栓颈的连接螺栓的栓颈直径。
下面借助附图对本发明的一个实施例作进一步详细说明，附图中：
图1为一个插在连接机架上且带有旋出的连接螺栓的连接件的立体视图；
图2为图1所示的连接件的一个剖视图；
图3为图1和图2所示连接件的底视图；
图4为一个插在连接机架上且带有旋入的连接螺栓的连接件的立体视图；
图5为图4所示连接件的一个侧面剖视图；
图6为图4和图5所示连接件的一个底视图；
图1以透视图示出由一个连接块1和一个连接螺栓2组成的一个连接件。该连接件***电器(例如继电器)的一个连接机架3。在***的连接块1之下，在连接机架3内成形有一个由两个弹性撑筋4组成的托架。这两个弹性撑筋逆箭头5所示的连接螺栓的安装方向突出。在此，连接螺栓2为带有一个栓颈6的组合螺栓。旋出的连接螺栓2以栓颈6搁置在撑筋4上，从而防止了自身旋入。为了确保这一点，撑筋4的间距小于栓颈直径，或在连接螺栓2没有栓颈6时小于螺栓纹根直径。
图2以侧面剖视图的形式示出带有***的连接件和旋出的组合螺栓2的连接机架3。
图3为图1和图2所示连接件的底视图。
图4、5和6以不同视图示出插在连接机架3上且带有旋入的组合螺栓2的连接件。在***整个连接件时，有两个弹性撑筋4的托架剪切式张开，从而这两个撑筋4不会受到伤害。为此这样来调整托架，使得在它的空隙内居中容纳连接螺栓2。这两个撑筋4遮盖螺栓直径的一半以上特别有利。
在旋出连接螺栓2时，它的螺纹几乎没有切入撑筋4，这是因为由于撑筋4弯曲，力相对微小。在旋出连接螺栓2之后，所述托架再次几乎完全回到其起始位置。该托架在接触到旋出的连接螺栓2的栓颈6后就保持住该连接螺栓2，使得连接螺栓肯定不会从螺纹中旋出栓颈长度。
