Description

电连接器
【技术领域】
本实用新型公开一种电连接器，尤其涉及一种表面焊接型电连接器。
【背景技术】
在现有的电连接器中，比如收容DDR的电连接器，端子收容于收容槽内，其自焊接部上方直至接触部均紧贴于收容槽的侧壁。在焊接过程中，由于端子的两侧与收容槽侧壁紧密配合，焊剂可能顺着端子与侧壁之间的间隙从焊接部爬至接触部或其附近，从而影响接触部的接触效果，此现象在工艺上称为爬锡现象，尤其在端子的接触部与焊接面距离较近的电连接器中，此爬锡现象尤为严重。
低构型板对板连接器亦有上述爬锡现象。板对板连接器一般设有四侧壁，端子的焊接部延伸出侧壁，接触部及连接焊接部与接触部的中间部贴附于侧壁上较浅凹槽内。在焊接过程中，焊锡亦有可能沿中间部爬至接触部，从而影响接触。
因此，有必要设计一种新的电连接器，以解决上述问题。
【实用新型内容】
本实用新型所要解决的技术问题是提供一种电连接器，其能防止爬锡现象。
为实现上述目的，本实用新型采用一种电连接器，可焊接于电路板，其包括一绝缘本体以及固定于绝缘本体内的端子，其中端子包括表面焊接于电路板上的焊接部、接触部及接续焊接部与接触部的中间部，焊接部焊接于电路板，其特征在于：绝缘本体在对应端子中间部的适当位置处设有凹缺口，使得中间部存在与绝缘本体间具有较大空隙的部位。
与现有技术相比，本实用新型电连接器的绝缘本体在对应端子的中间部开设有凹缺口，使得焊接时焊剂失去上爬的路径。
【附图说明】
图1是本实用新型电连接器的部分立体图，显示了电连接器右端结构。
图2是本实用新型电连接器的部分立体图，显示了电连接器左端结构。
图3是本实用新型电连接器上排端子的剖视图。
图4是本实用新型电连接器下排端子的剖视图。
图5是本实用新型电连接器的剖视图。
图6是图1的局部放大立体图，其中一端子被移除，以清楚显示凹缺口结构。
【具体实施方式】
请参阅图1、2所示，本实用新型电连接器的最佳实施例是一种可收容卡(未图示)的电连接器100，比如DDR。电连接器100具有一纵长绝缘本体1，其上设有一长槽10，长槽10两侧的侧壁上开设有连通且垂直于长槽10的收容槽11，用以收容上、下排端子，长槽10于其适当位置设有键扣12，起防呆作用。绝缘本体1于纵长方向的两端分别垂直地延伸出弹臂13，每一弹臂13外侧组装有一金属臂14以增强弹臂13的强度，金属弹臂14下缘向内垂直弯折出固定片143，该固定片143一端固定于绝缘本体1上，另一端向上弯折有止动片145。金属臂14的上缘向内弯折出一水平锁扣片144，其可突入DDR之缺口(未图示)内以防止DDR移动，该锁扣片144向下延伸有弯折片141，弯折片141与外侧壁配合紧贴于弹臂13起固持作用。金属臂14于固定片143的前端设有水平挡止片142，挡止片142抵挡于止动片145，可防止锁扣装置过度外张。弹臂13与金属臂14共同构成了可锁扣/解除DDR的锁扣装置。
请参阅图3、4所示，端子组2包括上、下排端子4、3。下排端子3具有主体部分30，主体部分30自其一端水平延伸出固持部31，于其另一端的上边缘延伸出的弹性部32，相对的下边缘延伸出接脚33，其中弹性部32与固持部31同方向，接脚33与固持部31反方向。上排端子4与下排端子3类似，其亦具有主体部分40、固持部41、弹性部42及接脚43。
上、下排端子4、3收容于上、下端子收容槽11内。请结合图5所示，下排端子3的固持部31借助其设有的倒刺35而干涉固定于绝缘本体下侧壁的槽道16内。弹性部32朝长槽10延伸，其末端超出下侧壁的顶面101(如图5所示)而形成可与DDR完成电性连接的接触部321。该端子的接脚33包括自主体部分30向下远离绝缘本体1倾斜延伸的延伸部331及继续水平延伸的焊接部332，焊接部332的底面焊接于电路板的导电片(未图示)上，形成焊接面333。上排端子4与下排端子3类似，于此不再具体叙述。
请结合图6所示，端子3紧紧地贴附端子收容槽11的两侧壁102上。以下为简单描述，将前述连接接触部321与焊接部332之间的部分(除固持部31外)统称为中间部。如图6所示，端子收容槽11的两侧壁102于临近焊接面333处被削除，形成上述凹缺口104，使得端子的延伸部331及主体部分30裸露，焊剂无法借助侧壁上爬，即失去了上爬的路径，而且，在制造过程中，该电连接器是射出成型的，直接在端子收容槽侧壁102的底部开设缺口104可以简化制程，节约材料。
当然，本实用新型不局限于上述实施例，亦可采用在收容槽的两侧壁适当位置分别对应形成凹缺口，使得该处两侧壁之间的宽度变大，如此，该部位的端子与侧壁有较大间隙，焊剂失去了上爬的路径，从而防止污染端子接触部。另，若上排端子4的接触部与焊接面距离较近，亦可类似下排端子3设计。在其他低构型连接器，比如板对板连接器中，亦可部分削除临近焊接部的侧壁，如此，焊锡失去了上爬的路径，达到防爬锡作用。
