Description

电连接器
【技术领域】
本实用新型有关一种电连接器,尤其涉及一种可焊接至电路板上的电连接器。
【背景技术】
相关现有技术可参阅于2001年5月29日公告的美国发明专利6,238,244号专利所揭示的一种用于与对接连接器相对接的电连接器,其包括有绝缘本体、设于绝缘本体上的若干导电端子、设于绝缘本体上的内壳及包覆在绝缘本体上的外壳,绝缘本体包括有两插接部,导电端子延伸入两插接部内,内壳设于两插接部之间,内壳向两插接部内分别凸伸有一对扣持弹片,外壳的上下两表面均设有卡持弹片,外壳的两侧面均设有抵压弹片,通常情况下,对接连接器的上下表面设有方形孔,内壳上的扣持弹片及外壳上表面或下表面的卡持弹片卡持在对接连接器的方形孔上从而可在前后方向上卡持住对接连接器,然而,当***后的对接连接器与内壳或外壳的上表面或下表面间留有间隙时,对接连接器将很容易上下摆动,从而导致了电连接器与对接连接器之间的接触不稳定,另外,外壳两侧的抵压弹片抵压在对接连接器两侧,同时可将对接连接器上的静电传导至外壳上,具有接地的功效,然而,当外壳采用成本较低的金属材料时,外壳两侧的抵压弹片耐插拔性较低,对接连接器在多次插拔后,外壳两侧的抵压弹片将产生变形从而不能保证与对接连接器可靠接触,从而影响了电连接器的接地效果。
因此,针对上述技术问题,有必要提供一种具有改良结构的电连接器,以克服上述缺陷。
【实用新型内容】
本实用新型的目的在于提供一种可保证与对接连接器可靠接触的电连接器。
为达上述目的,本实用新型采用如下技术方案:一种电连接器,其包括有绝缘本体、设于绝缘本体上的若干导电端子、设于绝缘本体上的内壳及包覆在绝缘本体上的外壳,绝缘本体包括有两插接部,导电端子延伸入插接部内,内壳设于两插接部之间,所述内壳向两插接部内分别凸伸有一对扣持弹片,其中,所述内壳还包括有向插接部内凸伸的抵压弯折片。
与现有技术相比,本实用新型具有如下有益效果:当***对接连接器后,内壳上的抵压弯折片抵压在对接连接器上,从而增加了对接连接器上下方向的夹持力,可防止对接连接器上下摆动,同时,该抵压弯折片可保证内壳与对接连接器可靠接触,具有良好的接地效果。
下面结合附图及较佳实施例对本实用新型作进一步说明。
【附图说明】
图1为本实用新型电连接器及对接连接器的立体图。
图2为本实用新型电连接器的立体分解图。
图3为本实用新型电连接器另一角度的立体分解图。
图4为本实用新型电连接器的内壳的立体图。
图5为本实用新型电连接器另一实施例的内壳的立体图。
【具体实施方式】
请参阅图1、图2及图3所示,本实用新型电连接器100包括有绝缘本体1、设于绝缘本体1上的导电端子2、包覆在绝缘本体1上的外壳3、设于绝缘本体1上的内壳4、组装至外壳3上的后盖5及组装至外壳3上的卡持片6。
请参阅图2及图3所示,绝缘本体1前端包括有上、下两个可与对接连接器200相对接的插接部15,两插接部15均包括有舌板12,于两插接部15之间设有一隔板13,绝缘本体1的后端两侧设有凸块14。
导电端子2包括有水平延伸的接触部21、尾部23以及连接接触部21和尾部23的固持部22。
外壳3的顶部与底部分别设有两铆接部即向外凸起的凸部32,外壳3于两凸部32的前端设有开孔36,外壳3的两侧上下位置均设有抵压弹片38,上下两抵压弹片38之间设有一卡孔33,外壳3的两侧后端设有卡槽35及固持孔34,外壳3的顶部后端设有固持孔34。
卡持片6的後端设有与外壳3上的铆接部即凸部32相铆接配合的配合部即铆接孔62,前端设有卡持部64,组装于外壳3顶部上的卡持片6为一体成型构造,组装于外壳3底部上的卡持片6为分开设置。
请参阅图4所示,内壳4的上表面及下表面均设有一对向前延伸的扣持弹片42以及位于对应两扣持弹片42之间且向后延伸的抵压弯折片43,内壳4的上表面及下表面后端均设有向后延伸的插接脚44,内壳4的两侧分别设有一弯折设置的卡片45,内壳4的前端设有一对向前弯折延伸的接地片46。
后盖5的两侧及上端均设有可与外壳3相配合的扣合部52。
请参阅图1、图2及图3所示,组装时,先将卡持片6组装至外壳3上即将卡持片6铆接在外壳3上,铆接时,卡持片6上的铆接孔62与外壳3上的凸部32相铆接配合,卡持片6上的卡持部64延伸入外壳3的开孔36内,将卡持片6与外壳3分开设置,所述卡持片6可由弹性较好的金属材料制成,从而具有较好的弹性及耐插拔性能,而外壳3则可由成本较低的另一种金属材料制成,如此设置,使电连接器100在保证了卡持片6的耐插拔性能的同时又降低了制造成本。将导电端子2组装至绝缘本体1上,导电端子2的接触部21分别设于绝缘本体1的两舌板12上。将外壳3包覆在绝缘本体1外,外壳3上的卡槽35与绝缘本体1上的凸块14相配合,此时外壳3上铆接的卡持片6的卡持部64凸伸入绝缘本体1的插接部15内,外壳3两侧上的抵压弹片38均凸伸入绝缘本体1的插接部15内。再将内壳4组装至绝缘本体1的隔板13上下方,内壳4上的插接脚44与绝缘本体1相配合,内壳4上的卡片45与外壳3上的卡孔33相配合,此时,内壳4上、下表面上的扣持弹片42及抵压弯折片43均分别凸伸入绝缘本体1的两插接部15内,最后将后盖5组装至外壳3上,后盖5上的扣合部52与外壳3上的固持孔34相配合,从而完成了整个电连接器100的组装。在本实用新型中由于外壳3、内壳4及卡持片6均为分开设置,故均可采用不同的金属材料制成。
请参阅图1、图2及图4所示,对接连接器200的上下表面均设有方形孔205,当***对接连接器200后,所述卡持片6上的卡持部64及内壳4上的扣持弹片42均扣持在对应的方形孔205上,从而可在前后方向上卡持住对接连接器200,内壳4上的抵压弯折片43抵压在对接连接器200上,从而增加了对接连接器200上下方向的夹持力,可防止对接连接器200上下摆动,另外,外壳3两侧的抵压弹片38抵压在对接连接器200两侧,同时可将对接连接器200上之静电传导至外壳3上,具有接地之功效,在外壳3采用成本较低的金属材料时,外壳3两侧的抵压弹片38耐插拔性较低,对接连接器200在多次插拔后,外壳3两侧的抵压弹片38将产生变形从而不能保证与对接连接器200可靠接触,因此,内壳4上的抵压弯折片43抵压在对接连接器上,可使内壳4与对接连接器200可靠接触,保证了电连接器的接地效果。
请参阅图5所示,在本实用新型的其它实施例中,内壳4的抵压弯折片43也可设置在内壳4上表面或下表面对应两扣持弹片42的同一侧,也可以是两个抵压弯折片43分别同时位于对应两扣持弹片42的左侧和右侧,同样可达到本实用新型的创作目的。
