Abstract
在制作振荡接收机时,在其外壳(10)与导线接头或插头(23)之间的过渡区域(30)内含有两个掏空区(31,32),从而形成相当薄的过渡区。为了增强机械稳定性,在掏空区(31)内制作有一条第一类横梁(41)。在另一掏空区(32)内作有两条横梁(42)。这两条横梁(42)锁贴在掏空区(32)的两侧,因此阻止了区域(30)的扭曲和朝向外壳(10)的弯曲。
Description
本发明涉及一种传感器,尤其是振荡接收机。
在DE-OS4403060.4中公开过一种振荡接收机,其外壳是由塑料喷涂而成。这种环绕喷涂层含有较大质量的塑料,尤其使得外壳与被喷涂的导线接头或插头之间的过渡区特别厚。使用大质量和厚过渡区主要为求得较好的机械稳定性。但却会引入非均匀的质量分布,给振荡接收机中探测元件的振动频率带来不利影响。特别在高频和特定频率段(例如在12KHz附近),负面因素会影响振荡接收机的特征曲线,使传感器的特征曲线出现紊乱或间断,导致与振荡接收机相连的测量系统或控制系统出错。
按本发明解决以上问题,可以通过如下方式:外壳和导线接头或插头之间的过渡区制作得很薄,而且在过渡区的上、下面至少有一横梁。不仅传感器的外壳而且导线接头均能具有较小的质量。特别是可以减少外壳与导线接头或插头之间过渡区的质量,那就是通过将该区掏空来减少质量。由此可以实现外壳体质量与导线接头或插头质量的分离。借助于沿导线接头或插头方向安置的上、下面横梁可以阻止导线接头的扭曲,从而可获得整个器件的稳定。通过制作掏空区,并使到导线接头或插头以及到横梁的过渡区平滑可以获得很低的机械应力和均匀的质量分布。这使得用压铸法制作相对简单。此外,振荡接收机也能得到良好的特征曲线。这种简单而快速的制作方法可以降低传感器生产成本,尤其质量的减少可降低成本份额。而且传感器更加不易损坏。
通过从属权利要求提及的方法能够在独立权利要求特征基础上作进一步的发展。
本发明实施例通过附图和后面的说明进行更详细的描述。
图1为振动传感器的纵剖面图;
图2为该振动传感器的俯视图。
图中描绘的振动传感器具有外壳10,其内部安装有密封套11,近下方底部是法兰盘12。在密封套11的外围,从法兰盘12开始安装有以下部分:绝缘垫片13,接触垫片14,压电陶瓷片15,再以相反顺序安装第二个接触垫片14和第二个绝缘垫片13。在其上装有一个振动体16。碟型弹簧17可对上述部分施加影响,其初始压力靠旋转螺纹环18产生,螺纹环18旋拧在位于密封套11上部的外螺纹19上。
扁形插头24向由合成材料做成的一体化接头23内,特别是向用压铸法制作的外壳10内喷射。这些扁形插头24与两接触垫片14相连。一个固定的螺栓(没画出)经密封套11的内孔28将该振动传感器与一个内燃机直接或间接地固定。按本发明在外壳10与导线接头23之间的区域30处,将上、下面作成掏空区31,32。掏空区31,32使区域30变得很薄,从而使外壳10与导线接头或插头进行机械隔离。外壳10的质量和形状就能作得差不多脱离于导线接头23了。掏空区31,32的底部33,34作成弧形以使得外壳10到导线接头或插头23之间具有平滑的过渡区。由此可以减少机械应力,使在喷铸过程中制作的导线接头或插头23和外壳10的质量具有均匀的分布。并使环绕密封套11的外壳10也能够具有质量上的对称性。另外,为了区域30的机械稳定性,即为了防止区域30出现扭曲以及防止导线接头或插头23向外壳10弯曲,在区域30处制作了横梁41,42。横梁41安装在掏空区31的中间。横梁41的上缘不仅平齐于导线接头23而且平齐于外壳10。在掏空区32的两边各作有横梁42,因此这两根横梁42就限制了掏空区32的边界。横梁42平齐于导线接头或插头23。横梁42的外壁与外壳10的斜壁也是平滑过渡的。自然,掏空区31或32上、下面横梁的配置和数目是可以交换或改变的。在使用3个横梁41,42时,横梁数少而且结构简单,同时具有很好的机械稳定性。
