Description

机动车辆座位安全带的带扣
技术领域
本发明涉及一种机动车辆座位安全带的带扣。 
背景技术
座位安全带通常包括一个连接至车辆的固定端的母元件和带有可插入所述母元件外壳的销的公元件，母元件设置有可锁定所述销的装置。 
由于系座位安全带是必须的，现代的车辆具有用于显示驾驶员和乘客没系安全带的装置。所述显示装置一般为仪表盘上的图标或者声音信号或者两者。 
母元件一般包括嵌入显示装置的供电电路的触点，该触点为闭合，从而所述显示装置被供电，当公元件的销插入时触点分离。 
通常，母元件包括在内部并安装成滑动形式的绝缘杆，该绝缘杆倚着弹簧运动并设计为在引入销后被销推动，从而被插入在两触点之间。 
座位安全带会被扣上或者解开很多次，特别是城市的车辆，并且已经注意到杆与触点的重复摩擦导致触点过早的磨损，从而存在显示装置不再起作用的危险。 
发明内容
本发明的目的之一是克服上述缺点。 
根据本发明的的座位安全带带扣，包括：含有绝缘外壳的母元件，所述绝缘外壳内安装有向显示带扣闭合或断开的装置供电的供电电路，该电路包括常闭电触点，该电触点可被所述外壳内的移动绝缘杆倚着弹簧装置的运动而分离；以及安装在带上的公元件，该公元件包括用于与所述母元件的槽相接合的销，且该销可通过无锁定元件扣紧在所述母元件上，所述销进入所述槽引起所述杆的控制电触点分离的运动，其特征在于：所述电触点由两个舌片支撑，第一舌片具有V形部分，该V形部分具有两个分支，其中一个分支形成电接触及弯曲端，所述两分支的凸起部分与第二舌片相对，该第二舌片具有V形部分，该V形部分具有两个分支，其中一个分支形成电接触并且设计为承受第一舌片的电接触，所述弯曲端设计为与所述杆相互作用以控制电触点的断开。 
通过这种设置，电接触区与机械接触区分开，事实上可移动的绝缘移动杆并不影响电接触，并且电接触彼此之间的分离或者应用不产生明显的摩擦。 
根据一个实施例，所述第二舌片具有延长了的弯曲部分，该弯曲部分的凸起部分与所述第一舌片的弯曲部分相对。 
所述舌片其中之一的弯曲部分穿通有开口，另一个舌片的凸起部分插入该开口。 
所述电触点为滑动触点型。 
下面将结合附图和具体实施例对本发明作详细描述，这些实施例只作为例证性。 
附图说明
图1展示了插入销时安全带带扣的剖视图； 
图2与图1类似，销接合并锁定； 
图3为细节透视图； 
图4和图5为展示作用的透视示意图； 
图6和图7为本发明另一实施例的透视图。 
具体实施方式
如图1至5所示，座位安全带的带扣包括带有槽2和销3的公元件1，其中槽2用于插入安全带，销3设置在一端并带有用于固定锁紧钩的开口4。 
该座位安全带的带扣还有母元件5，该母元件为带有槽6和缩进装置的绝缘外壳形式，槽6用于引入销3，缩进装置使得销可以从母元件中移除，从而打开安全带。这些设置是常规的，所以这里不详述。 
母元件5内设置有金属壳7，该金属壳具有两个伸长状的开口8，该开口为移动绝缘杆10的导向轨道，使之倚着压缩弹簧11移动，该压缩弹簧安装在所述金属壳7内。 
所述金属壳的一侧上设置有电路15和16，该电路15和16用来接入向显示装置供电的供电电路，如图3所示。 
优选地，电路15和16为冲压出的电路，其上形成有弯曲突起17，作为电导体的分支。 
电路15的形状为具有伸长的舌片18，该舌片有一部分折成V形以形成两个分支19和20，分支20连接至直线部分21，该直线部分21与分支20形成弯曲，并在末端带有含槽23的弯曲末端部分22。所述V形部分的突出部分和所述圆弧的突出部分形成于与电路的互补舌片25相对的方向。 
所述互补舌片25折有V形部分，该V形部分具有两个分支26和27，直线部分28与分支27形成弯曲，末端为带有槽23的圆弧形末端部分29。 
V形零件的凸起部分和互补舌片的圆弧形成于与舌片18相反的方向。 
舌片18和25的V形部分设置为：静止位置时，分支27承受分支19，所述各分支形成滑动型电触点以保证自净。 
弯曲末端部分22和圆弧形末端部分29的自由端设置在绝缘杆10的轨道上。 
在使销3插入槽6后，销逆着弹簧11推动绝缘杆10，从而绝缘杆被插入在弯曲末端部分22和圆弧形末端部分29之间，分支27和分支19被弹性地相互分开，从而断开电路。利用此方式，滑动型电触点被分离和闭合且几乎无磨损，如图4和图5所示。 
图6和图7展示了一个实施例，其中电路15a包括舌片30，该舌片30具有V形部分，V形部分具有两个分支31和32，分支32由直线部分33延长至末端的弯曲端34，同时电路16a设置有舌片35，该舌片35具有端部V形部分，该V形部分具有两个分支36和37。 
分支31和37形成电接触区，该电接触区如前述的实施例作为滑动接触型。 
当带扣没有闭合时，分支37与分支31相互作用，以闭合显示装置的电路，反之，当销插入所述槽中，销推动杆10，杆10与弯曲端34相互作用以使带扣31与分支37分离。 
当然，本发明不限制在上述的实施例。在不超出本发明的范围的情况下，修改许多细节都是可能的。
