Abstract

本实用新型涉及用于工业和/或第三级用途的电插座或插头,它包括一个包含两个互补元件的壳体(10),并装有一个弹簧状舌(16)形式的弹簧状止动装置,它与壳体的元件之一形成一体,并通过弹性与壳体的另一元件上的支持台肩(19)接合。

Description

电插座或插头
本实用新型一般涉及用于工业和/或第三级用途的电插座或插头,并且尤其涉及所述插座或插头的壳体。
用于工业或第三级用途的电插座或插头通常包括一个壳体和一个连接插口,后者被包围在该壳体中并具有用来与互补插座的开口连接的销,或用来与插头的销连接的开口。一般,壳体包括一个夹紧元件和一个插口夹持元件,并且所述两个元件通常用一种卡口型连接在轴向相互固定。
根据一种当前实施例,这种连接是通过在要连接的两个元件的部件之间插入一个扁簧来形成和紧固的。一旦两元件连接后,该弹簧防止它们的无意的或偶然的分离。然而,插入的弹簧的存在导致装置的装配阶段的问题和复杂。
本实用新型的目的是通过消除插入的弹簧来防止这些问题。但是仍然保证在形成电插座或插头的壳体的两个元件之间的有效连接和固定。
此目的是根据本实用新型用至少一个圆簧状舌来实现的,它是通过模压与插座或插头壳体的元件之一制成一体,并且当装配所述壳体时,用于通过弹簧与另一元件干涉接合,以防止其无意的分开。
本发明的进一步的细节将从以下参照示意性的非限制性附图的描述,而更加清楚。
图1示意表示了分解的电插头的壳体的两个元件;
图2表示具有簧状舌的元件的前视图;
图3表示装配的插头壳体;
图4表示装配的插头壳体的截面图。
在所述附图中,电插头的壳体均用10表示。此壳体包括一个夹紧元件11和一个夹持元件12。夹持元件12夹持一个连接插口,在所示的实例中,它具有销13(图3)。夹紧元件11具有插入插口夹持元件12的凸缘12’的凸缘11’。两元件11、12通过卡口型连接来连接。
为此目的,夹紧元件11的凸缘11’具有两个径向凸棱14、14’,插口夹持元件12的凸缘12’具有两个座或槽15、15’用来通过沿轴向将一个元件相对于另一元件旋转,而容纳凸棱14、14’。
夹紧元件11还具有至少一个弹簧状止动舌16,一旦两个元件11、12被连接,用于保持它们之间的固定。
根据本实用新型,舌16通过模压,与元件11制成一体。更确切地说,所述弹簧状舌16是元件11的径向凸棱14的一端的延续,它向与旋转方向相反的方向延伸。该旋转使壳体的两个元件之间的卡口连接成为可能。弹簧状舌16的另一端是向外转的齿17。另一方面,可以在用于容纳凸棱14的座或槽15之一的底部提供凸轮面18,它在壳体的两个元件11、  12的连接期间适于使弹簧状舌16弯曲(向内)。
实际上,在为连接两元件11、12而相应地旋转它们时,弹簧状舌16首先被弯曲,被弹性加载。这是由于其端齿17与簧状舌16所插入的座或槽1 5的底部和/或凸轮面18的接触。然后,当凸棱14与限位止动行程对上时,弹簧状舌16反弹,回到初始位置,其端齿17与座或槽的端部的台肩19接合。与舌成一体的凸缘靠在相对的一端上(图4)。舌的齿17防止壳体的一个元件相对于另一元件的相反的转动,从而制止它们的无意的或偶然的分开。事实上,壳体的两个元件11、12的拆开只能通过从外侧插入工具使舌16向内弯曲,直到齿17离开支持台肩19。
在弹簧状舌17的自由端可以提供一个附件20,它延伸超过齿17,当元件被连接并且齿17与台肩19接合时,在座或槽15的边缘处与元件12的凸缘的内侧接合。这样的附件的作用是防止弹簧状舌由于一个元件相对于另一元件的被迫旋转,而被向外弯曲和推出,从而变形。
最后,应该注意凸棱和槽的位置可以颠倒,前者在插口夹持元件上,后者在夹紧元件上。

Claims (8)
