Description

插座
技术领域
本发明涉及一种插座,特别地,涉及一种利用操作用螺丝刀来连接引线的插座。
背景技术
一直以来,作为使用操作用螺丝刀来连接引线的插座,例如有壳体内安装有由承受金属件和弹簧构件构成的连接金属件的插座。并且,还有利用插入所述壳体内的操作用螺丝刀来使所述弹簧构件弹性变形,从而用所述承受金属件和所述弹簧构件来夹持引线的插座(参照专利文献1)。
专利文献1:德国专利第102009004513号公报
发明内容
但是,就所述插座而言,如图10所示,有如下问题:当将操作用螺丝刀56插入壳体52而使弹簧构件10产生弹性变形时,所述操作用螺丝刀56的操作发生错误,则导致所述弹簧构件10产生塑性变形。
鉴于上述问题,本发明的插座的课题在于提供一种能够防止所述连接金属件的弹簧构件的塑性变形的插座。
本发明的插座用以解决所述课题,具有基体和连接金属件,所述所述连接金属件具有承受金属件和弹簧构件且安装在所述基体的上方面,通过按压所述连接金属件的所述弹簧构件使其弹性变形,从而能够用所述承受金属件和所述弹簧构件来夹持引线;其中,在所述基体的上方面凸出设置限位凸部,所述限位凸部与被按压变形的所述弹簧构件抵接而防止所述弹簧构件塑性变形。
根据本发明,当利用操作用螺丝刀来按压弹簧构件以使其产生变形时,所述弹簧构件抵接在限位凸部而被限位,因此能够防止所述弹簧构件的塑性变形。
作为本发明的实施方案,所述限位凸部也可与所述基体一体成形。
根据本实施方案,部件数量、组装工时减少且生产性高。
作为本发明的其他实施方案,也可在所述限位凸部的上端部形成限位用锥面,所述限位用锥面与所述弹簧构件面接触。
根据本实施方案,由于弹簧构件与限位凸部的限位用锥面面接触而被限位,因此插座中应力集中现象很难发生,进而使所述弹簧构件更难产生塑性变形。
作为本发明的其他实施方案,也可在所述连接金属件的所述承受金属件设有嵌合孔,所述嵌合孔嵌合于凸出设置在所述基体的所述限位凸部。
根据本实施方案,通过所述基体的限位凸部能够将所述承受金属件准确地安装在基体上,插座的组装精度高。
作为本发明的不同的实施方案,也可以是引导用隔壁以架设在罩的顶面及内侧面的方式与罩一体成形,所述罩为与所述基体嵌合且覆盖所述连接金属件的箱形罩,并且,
所述引导用隔壁卡合在设置于所述连接金属件的承受金属件及所述弹簧构件的狭缝上,
利用从设置在所述罩的顶面的操作孔沿所述引导用隔壁插入的操作用螺丝刀,来按压所述弹簧构件的压接弹簧以使其弹性变形。
根据本实施方案,以架设在罩的顶面及内侧面的方式与罩一体成形的引导用隔壁卡合在设置于连接金属件的承受金属件及所述弹簧构件的狭缝。从而,所述引导用隔壁将所述弹簧构件的相邻的压接弹簧隔开。结果,不会错误地插入引线,组装精度提高,并能够防止插座发生连接不良。
另外,所述引导用隔壁以架设在罩的顶面和内侧面的方式与罩一体成形。因此,即使错误插入操作用螺丝刀,所述引导用隔壁也不会断裂,不产生断裂片。结果,插座不会因所述断裂片而发生连接不良。
根据本发明的新的实施方案,也可在所述引导用隔壁的下端边缘部设有切槽部,所述切槽部卡合在所述基体上设置的所述限位凸部。
根据本实施方案,具有如下的效果,即,插座的所述引导用隔壁的支撑强度进一步增强,不仅不会发生连接不良的情况,罩整体的刚性也增大,具有坚固的结构。

具体实施方式
根据图1至图14的附图对本发明的插座的实施方案进行说明。
如图1至图10的附图所示,第一实施方案的插座由基体10、连接金属件20和罩40形成。
如图6所示,在基体10的上方面凸出设置台座部11来形成环状台阶部12。在所述台座部11的上方面中的较低的上方面11a设有连接孔13。另外,在所述台座部11的上方面中的较高的上方面11b的边缘部凸出设有支撑凸部14。并且,限位凸部15在所述上方面11b的大致中央处,与所述上方面11b一体成形。
在所述限位凸部15的上端部具有限位用锥面16。进而,在所述台座部11的沿着长尺寸方向且相向的外侧面分别凸出设有卡合钩部17、17。
此外,在本实施方案中,所述限位凸部15与所述基体10一体成形,并且在所述基体10安装后述的连接金属件20。因此,所述连接金属件20的定位精度高且组装误差小。结果,当利用操作用螺丝刀(未图示)来按压所述连接金属件20的压接弹簧35时,按压位置不产生偏差,因此能够有效防止塑性变形的发生。
特别地,所述限位用锥面16具有倾斜角,当后述连接金属件20的压接弹簧35发生了弹性变形时,该倾斜角使所述限位用锥面16可以与所述压接弹簧35面接触。因此,能够有效防止所述压接弹簧35的塑性变形。
如图6所示,连接金属件20由承受金属件21和剖面大致呈V字形状的弹簧构件30形成。
就设有贯通孔21a的所述承受金属件21而言,通过冲压加工将导电性金属板弯曲,由此在一侧设置保持部22,并且在另一侧形成有铆接部23、底部24及压接部25。
所述保持部22具有能够通过铆接加工来保持未图示的引线的形状。另外,在所述铆接部23的表面通过冲缘加工形成有多个铆接用凸起26,并且所述底部24形成有方形的嵌合孔27。并且,形成在所述压接部25的自由端部的狭缝28将所述压接部25在宽度方向上一分为二,形成一对压接承受部29、29。
所述弹簧构件30被弯曲成大致V字形状,所述弹簧构件30的一侧的铆接部31设有多个铆接用小孔32和铆接用大孔33。另外,在所述弹簧构件30的另一侧的弹性变形的自由端部设有狭缝34,由此形成一对压接弹簧35、35。
并且,在所述承受金属件21的铆接用凸起26、26上铆接固定所述弹簧构件30的铆接用小孔32、铆接用大孔33,从而将所述弹簧构件30的压接弹簧35、35的顶端部分别压接在所述承受金属件21的压接承受部29、29。
从而,将设置在所述承受金属件21底部24的嵌合孔27嵌合安装在所述基体10的限位凸部15。并且,将经由所述基体10的连接孔13从下方插入的未图示引线铆接固定在所述承受金属件21的保持部22,从而实现电连接。
如图4所示,罩40具有可嵌合于所述基体10的环状台阶部12的箱形,且具有阶梯形状,即,在罩40的上方面的一侧具有台阶部41。并且,在所述台阶部41的上方面中的、与所述基体10的支撑凸部14的上端面相对应的位置上形成有凹部42。另外,在所述凹部42的底面设有与所述承受金属件21的贯通孔21a连通的贯通孔43(图5)。因此,能够将所述承受金属件21经由所述罩40的贯通孔43电连接于邻接的其他插座(未图示)的承受金属件21。
另外,在所述罩40的除了所述台阶部41以外的上方面中的、与所述压接弹簧35的中间区域相对应的位置上设有能够插入未图示的操作用螺丝刀的操作孔44。并且,在所述罩40的除了所述台阶部41以外的上方面中的、与所述压接弹簧35的自由端部相对应的位置上设有能够插入引线的插入孔45。在所述插入孔45的开口边缘部形成有用于使引线容易插入的倒角部45a。
进而,所述台阶部41的角部设有形成为大致半圆弧面的引导用切槽部46,用以引导向所述操作孔44插入的操作用螺丝刀。
并且,如图4及图5所示,引导用隔壁47以架设在所述罩40的顶面和内侧面的方式与所述罩40一体成形。所述引导用隔壁47分别卡合于所述承受金属件21的狭缝28及所述弹簧构件30的狭缝34。另外,在所述引导用隔壁47的下端边缘部具有卡合于所述基体10的限位凸部15的切槽部48(图5)。
并且,在所述罩40的相向的侧面中设有卡合于所述基体10的卡合钩部17的卡合孔49(图6)。
并且,将罩40嵌合在所述基体10的环状台阶部12,从而使所述罩40的卡合孔49与所述基体10的卡合钩部17卡合而成为一整体(图1)。由此,所述罩40的引导用隔壁47卡合于所述承受金属件21的狭缝28及弹簧构件30的狭缝34(图4)。进而,引导用隔壁47的切槽部48卡合于所述基体10的限位凸部15,压接弹簧35、35被隔开。
将引线连接在所述插座时,如图10所示,将操作用螺丝刀50插入操作孔44来按压所述压接弹簧35的中间区域,从而按下所述压接弹簧35。之后,将从所述插入孔45插入的引线定位在所述压接弹簧35的顶端部和所述压接承受部29之间。接着,拔出所述操作用螺丝刀50,由此所述压接弹簧35弹性复位,所述引线被所述压接弹簧35的顶端部和所述压接承受部29夹持。
另外,拆下所述引线时,将操作用螺丝刀50插入所述操作孔44中,按压所述压接弹簧35的中间区域来按下所述压接弹簧,由此能够拆下所述引线。
根据本实施方案,当用操作用螺丝刀50按下压接弹簧35时,所述压接弹簧35被限位在限位凸部15的限位用锥面16。因此能够防止压接弹簧35的塑性变形。
如图11至图14所示,第二实施方案的插座几乎与上述第一实施方案相同,不同点在于,设置在罩40的台阶部41的引导用切槽部46形成为一对三角形锥面,该三角形锥面是平坦的锥面。
所述引导用切槽部46由一对平坦的三角形锥面形成。因此,沿着所述引导用切槽部46插入操作用螺丝刀(未图示),使所述操作用螺丝刀的定位变容易。结果,能够准确而迅速地利用所述操作用螺丝刀来操作所述压接弹簧35。
特别地,当操作用螺丝刀沿着所述引导用切槽部46插入时,所述压接弹簧35的弹力作用于操作用螺丝刀。因此,所述操作用螺丝刀的保持状态稳定。
另外,如果不设置所述引导用切槽部46而直接使所述操作用螺丝刀触碰所述罩40的角部,则所述罩40的角部容易磨损。但是,通过设置所述引导用切槽部46,使所述操作用螺丝刀与所述引导用切槽部46线接触。因此,具有所述罩40不易被磨损的优点。
其他方面与上述第一实施方案相同,因此对相同部分标注相同附图标记,省略说明。
实施例1
如图15及图16所示,对利用操作用螺丝刀50来按下上述实施方案的所述弹簧构件30的压接弹簧35的中间区域所引起的弹性变形时的应力分布进行分析。分析结果如图17所示。
从图17中明显判断出,内部应力容易集中在所述弹簧构件30的弯曲部36,特别是弯曲部36的铆接部31侧。
此外,如图17所示,在上述实施方案中设有所述限位用锥面16,以使所述弹簧构件30的压接弹簧35在弹性变形范围内与限位凸部15的限位用锥面16抵接。因此,能够防止所述压接弹簧35的塑性变形。
工业上的可利用性
本发明的插座不限于上述插座,例如可适用于能够连接四根引线的插座。
