Straight cutting Duckbill type terminal
Technical field
The utility model relates to a kind of binding post, specifically a kind of straight cutting Duckbill type terminal.
Background technology
Binding post is a kind of for realizing the accessory product be electrically connected.Along with industrial automatization is more and more higher and Industry Control requires more and more stricter, accurate, the consumption of binding post goes up gradually, and the scope of application gets more and more, and kind also gets more and more.
Disclose a kind of internal pole terminal in Chinese patent literature documents CN101192724A, comprise tubular portion, this tubular portion has square tubular form and holds inserted terminals wherein; And elastic component, this elastic component is arranged in this tubular portion, so that the inner surface towards this tubular portion promotes this inserted terminals, wherein this elastic component comprises the sweep formed by the conductive metal sheet of band shape, with a pair mounting portion, this mounting portion is formed on the relative lateral edges of the width of this sweep respectively and extends away from each other; Wherein this barrel portion has a pair mutually relative sidewall, and have to be separately positioned on for a pair this sidewall penetrates window, this inserts this to penetrating in window respectively to mounting portion, and be wherein separately positioned on this penetrate each mounting portion in window at least partially in thickness other parts of mounting portion more each than this large.This internal pole terminal can prevent elastic component and tubular portion from departing from, and reduces the swing of this elastic component.
But internal pole terminal disclosed in above-mentioned patent documentation, its mounting portion is inserted respectively and is penetrated window in the mutually relative sidewall of a pair of barrel portion, and structure is loaded down with trivial details, installs complicated; Conductive metal sheet with sigmoid can be squeezed when wiring male terminal inserts slot and to move downward and the elastic force produced upwards is strengthened being fixedly connected with, when taking out wiring male terminal, conductive metal sheet with sigmoid away from slot socket one end suffered by extruding force disappear, rebound to vacant state under the effect of elastic force.Long-term wiring male terminal inserts and extracts, and the elastic performance of the conductive metal sheet being with sigmoid is declined, as easy as rolling off a log damage.In addition, the insertion of size to male terminal of this internal pole terminal tubular portion also has a certain impact: if tubular portion size is little, and the distance between upper wall portions and diapire is too near, then male terminal inserts inconvenient; If tubular portion size is large, between upper wall portions and diapire apart from too far away, then after causing male terminal to insert, the dynamics of locking is inadequate, easily gets loose.
