Description

压触式端子接头
本发明涉及一种压触式电端子接头。
压触式电端子接头的内部以一种统一的方式具有压触刃,在它们之间界定了一个槽。当电线被插入槽中时,刃边缘切割过电线的绝缘外皮,由此与导电芯线相接触。在这种方式下,压触式端子接头在电线和端子接头之间实现电接触。这种压触式端子接头具有无需刮削处理以暴露芯线端部的优点,而在通过夹紧或钎焊筒形件来连接电线的端子接头上,则需要这种处理。
附图中的图6示出了一种传统的压触式端子接头。端子接头40有二对在前部和后部形成的压触刃45,且位于压触段41内,压触段41的上表面敞开,形成了一个通道,相对的侧壁42被切开以形成一对相对的突起件43它们构成了压触刃45。压触槽44在突起件43之间形成。提供二对刃45的原因是由于芯线通常由多股细缠绕线组成,只提供一对刃45会导致在实现压力接触后芯线松开,这样会导致芯线脱离槽44,否则也会降低电接触力。如果提供二对压触刃45,则可避免发生芯线松散和接触不好的情况,并且提高了电接触的可靠性。
在具有上述结构的压触式端子接头40中,形成压触刃45的突起件43被从侧板42上切开。然而,侧壁42以一种统一的方式形成且带有筒形件46,该筒形件通过围绕电线压触部分的后端被夹紧来固定电线。因而,由于筒形件46被夹紧,侧壁42具有通过弯曲变形的趋势,从而导致压触槽45宽度的轻微改变。这样不利地影响到压力接触的可靠性。
图7示出了一种不同类型的现有的压触式端子接头。端子接头50具有通过在压触段51的底板上切开、在前部和后部形成的二压触刃53,压触刃53具有在其上形成的压触槽52。在这种结构中,由于压触刃53被从底板54上切开,即使侧壁55伴随着夹紧筒形件56而弯曲,压触槽52的尺寸精度也不会由于弯曲而受到影响,从而与图6中的端子接头40相比,具有较高的接触可靠性。然而,由于二压触刃53均从底板54上切开,因此在底板54的总长度上存在问题,即端子接头50的长度比其它现有的端子接头40的长度更大。
图6中的端子接头40和图7中的端子接头50都有它们各自的优点和缺点,因此要求进一步的改进。本发明在考虑了上述问题后进行了发展,目的在于保持较短的长度,同时达到压力接触的高可靠性。
根据本发明,提供了一种压触式端子接头,其包括一个基底和二个直立侧壁,它们界定了一个通道,和在所述通道一端的夹紧筒,该端子接头还包括二对相对的刃,适用于接受电线,第一对所述刃较靠近所述夹紧筒,且从所述基底上被部分地切开,第二对所述刃较远离所述夹紧筒,且从各自所述的侧壁上被部分地切开。
这种端子接头具有优点,即当夹紧筒被夹紧时,后部的刃(邻近夹紧筒)不受影响而变形。而且,前部的刃是从各自的侧壁上切开的,其使接头不变长,同时使随之产生的开口布置在接头的周围。后一优点降低了局部的压力,并且提供了在接头中均匀的分布。
作为优选,后部的刃朝着夹紧筒向上弯起,而前部的刃远离夹紧筒相内弯起。
本发明的其它特点将在以下仅在附图中通过举例示出的优选实施例的详细描述中清楚地体现,其中:
图1为第一实施例的斜视图,示出了电线插入之前的状态。
图2为第一实施例的局部平面图。
图3为第一实施例的斜视图,示出了插入的电线。
图4为沿图3中X-X线的剖面图。
图5为沿图3中Y-Y线的剖面图。
图6为现有技术连接器的斜视图。
图7为另一现有技术连接器的斜视图。
本发明的第一实施例在以下参照图1至5进行说明。
本实施例适用于阴压触式端子接头,其通过首先将导电金属片切割,然后成型出如图1所示结构的方法形成。端子接头10以从前端到后端为序,包括:连接段11,其与相应的阳端子接头(未示出)相连接;压触段12,其上表面是敞开的,形成凹槽形,压触段12与电线1的终端实现压力接触;以及筒形件13,用于夹紧电线1的压触部分的后端。
位于前端的连接段11为带两层顶面的具有斜度的管形。其内部具有弹性接触元件15,它可与相应的阳端子接头的突出部以弹性方式相接触。而且,通过切开顶面形成了撞杆16。当端子接头10被插入连接器壳体(未示出)的空腔时,撞杆16被位于空腔中的定位元件阻挡,使端子接头10被卡住处于不可移动状态。顶面的一边缘具有一与其相连的稳定面17,用于防止端子接头以错误的方式插入,并且用于在连接器壳体(未示出)内保持稳定的插入。
筒形件13为一对,被置于后端,从侧壁20上突起,而侧壁20从压触段12的侧壁19延伸而来。筒形件13相互之间在前后方向上被轻微移位。
压触段12具有压触刃21和22,它们分别位于前部和后部。如图4所示,位于前部的压触刃21通过部分切开的内弯的一对突起件24形成,突起件24从压触段上相对的左、右侧壁19上伸出,它们彼此相对。在突起件24的突起边缘之间形成了压触槽25。压触槽25的宽度被设为规定的尺寸,其略小于电线1的芯线3的直径。
如图2中的虚线所示,位于后部的压触刃22通过从压触段12的底板27上被部分地切开而形成,其带有已经在压触刃22上形成的压触槽29。然后,压触刃22的底端被弯曲使压触刃22朝上与其原始位置相垂直。并且与位于前部的压触刃21保持规定的距离。压触刃22上压触槽29的宽度与前部的压触刃21上压触槽25的宽度相同。
下面,对电线的压触过程进行说明。
如图1中箭头所示,电线1的终端从端子接头10的上面朝着压触刃21和22插入。如图4和5所示,由于位于前部和后部的压触刃21和22,电线1的外皮2被压触槽25和29切入,芯线3与压触槽25和29的边缘相接触。在这种方式下,电线1和端子接头10通过位于前部和后部的二压触刃21和22实现电接触。接着,置于压触段12后部的一对筒形件13被弯曲压紧在电线1上以使它们围绕着它。如图3所示,这样使端子接头10与电线1固定在一起。
当如上所述的压力接触发生时,由于压触槽29是在位于后部的压触刃22上通过切开底板27预先形成的,因此压触槽29的尺寸精度从其最开始时始终是高的。而且,由于压触刃21通过从左、右侧板19切出突起件24而形成,并且由于压触刃21位于前部且与筒形件13有一定距离,因此,当筒形件13被夹紧时,侧板19因筒形件13的弯曲而不受影响,且压触槽25的尺寸保持相对的精确。在这种方式下,可以保持对电线1的高度可靠的压力接触。而且,由于压触刃21和22分别从侧板19和底板27上切出,因此,与二压触刃均从底板27上切出的情况相比,压触段12的长度,也就是说,端子接头10的长度可以做得更短。另外,在切出压触刃21和22之后形成的开口30和31分布在侧板19和底板27之间,因此使压触段12保持了一个均匀的强度。
本发明不仅仅限制于上面结合附图所描述的实施例。例如,下面描述的可能性也在本发明的技术范围内。另外,本发明在不脱离其范围的情况下,可以各种其它方式来实现。
(1)在压触刃通过从侧板上切开突起件而形成的情况下,同样可以使由于切开而形成的开口布置成出现在突起件的前部。而且,在压触刃通过从底板上切开而形成的情况下,可以以同样的方式切开而使开口出现在压触刃的后部。
(2)与在上述实施例中描述的阴压触式端子接头的应用相对而言,本发明可以同样地适用于阳压触式端子接头。
