Description
本发明涉及一种弹簧夹,它具有一个设在接线区内的夹体。一根引入接线区内的具有一电线轴线的电线借助该夹体在弹簧力作用下可被夹固在一个夹紧位置上。
这类夹子例如有由Wago公司销售的笼式拉力弹簧。但也公知了另一些种类的弹簧夹。
目前现有的弹簧夹使用起来十分麻烦,为了引入电线,必须借助一个工具用力将夹子张开。因此,要夹住导线十分困难。
本发明的目的在于提供一种便于使用的弹簧夹,尤其是一种可单手操作的弹簧夹。
本发明的目的可由此实现,
-在将导线引入接线区之前,将夹体保持在预张紧位置,
-在将导线引入接线区后,松开夹体。
在本发明弹簧夹的一有利结构中,
-该弹簧夹具有两个设置在夹体中并相互铰接的夹紧臂,为了将夹体保持在预张紧位置,这两个夹紧臂保持在略微超出死点位置之处,
-在将导线引入接线区后,夹紧臂可从死点位置移出。
在另一种技术方案中,借助一个可松开的制动机构将夹体止动在预张紧位置上。该制动机构优选承受弹簧加载。
夹体可通过受外力操纵而松开。但优选通过轴向移动电线,如通过推、拉电线来松开夹体。
当电线通过一个释放元件与夹紧臂或制动机构有效连接时,可特别容易地松开夹体。
当夹体具有一个用于切开导线可能有的绝缘皮的切削刃时,就省去了在将导线引入弹簧夹之前需去除其绝缘皮。
下面借助附图所示实施例对本发明的其它优点和细节予以详细说明,附图中:
图1示出一个弹簧夹;
图2示出处于预张紧位置的一个夹体;
图3示出松开时的夹体;
图4示出处于夹紧位置的夹体;
图5示出另一个弹簧夹。
按照图1,一个弹簧夹具有一个接线区1。在该接线区1内设有一个夹体2。借助该夹体2,一根伸入接线区1内的具有一电线轴线4的电线3可在弹簧力作用下夹紧在一个夹紧位置上。
在夹体2内设有两个夹紧臂5,它们通过一个铰接头5′相互连接。这两个夹紧臂5可经过移动略微超出死点位置一点。这样在两个夹紧臂5之间可构成一个稍许优角的(ueberstumpfen)张开角α。该张开角α在180°和最大190°之间。该张开角α由于两个夹紧臂5的结构被限定在这一数值上。通过将夹紧臂5张开角度α,张开夹体2并将其保持在一个引入导线3前所确定的预张紧位置上。通过一个未示出的操纵机构张开夹体2。该操纵机构例如可以是一个螺丝刀,它通过(插在)弹簧夹和夹紧体2内的间隙中可作用于夹紧臂5。
下面结合图2-4对图1所示弹簧夹的工作原理予以详细说明。
在沿轴向X将导线3引入接线区1时,一个释放元件6与其底点7同样沿轴向X运动。只要导线3沿引入方向X运动,夹体2就不会松开。
释放元件6在其底点7具有夹钳8。在试图将导线3逆其引入方向X从接线区1内重新拉出时,该夹钳8会钳住电线3或其绝缘皮3′。所述释放元件6支承在一个铰接点9上。该铰接点9在铰接头5′附近。在最有利的情形下,该铰接点9与铰接头5′完全合并成同一个铰接点。
释放元件6与夹紧臂5有效连接。在将导线3引入接线区1后,通过往回拉动导线3且随之夹钳8钳住导线3或其绝缘皮3′,夹紧臂5首先从其静止位置移动到死点位置。这一状态由图3示出。
在将导线3进一步从接线区1拉出时,夹紧臂5从死点位置移出。夹体2由此被松开。通过导线3的轴向运动,夹体2被释放或松开并由此弹回其夹紧位置。
夹体弹回其夹紧位置是在弹簧力作用下完成的。该弹簧力可同时被用于切开导线3可能存在的绝缘皮3′。夹体2为此具有一个切削刃10。
上述弹簧夹可以有许多不同变型。导线3例如可以直接作用在夹紧臂5上。在这种情形下,在将导线3引入接线区1中时就开始松开夹体2。此外,带有底点7的释放元件6在预张紧状态下可抵压在一个止挡上。这样一种结构使铰接头5′承受的机械负荷变得最小。与之相反,图示实施形式具有的优点是,上述弹簧夹可以无需外力释放就能松开,因而尤其可用单手操作,而且对柔软导线也同样适用。
在图5中示出了本发明弹簧夹的另一实施形式。在该实施形式中,夹体2具有一个卡槽11,夹体2借助它并另外通过一个可松开的、承受弹簧负载的制动机构12可被锁止。在将导线3引入接线区1后,首先是弹簧夹的释放元件6同样沿引入方向X运动。在尝试将导线3从接线区1拉出时,释放元件钳住导线3。由此将制动机构12从卡槽11中抽出,这样夹体2就突然从预张紧位置转换到夹紧位置,进而将导线3夹住。此外,图5所示弹簧夹的功能与图1-4所示弹簧夹的功能一样。相同的元件也因此具有相同的附图标记。
