摘要：
In a conventional configuration, a lead line weld joined portion 55 between a lead line and an end of a terminal is disposed internally of an magnetic circuit, i.e., of a yoke portion 51. This increases the total length of the magnetic circuit, i.e., the yoke portion 51 by the axial dimension of the lead line weld joined portion 55. This will increase the magnetic resistance of the magnetic circuit, which leads to a problem with a reduction in the magnetic biasing force occurring between a first core portion 33 and an anchor 35.
In the present invention, the lead line weld joined portion 55 is disposed externally of the magnetic circuit, i.e., of the yoke portion 51. This eliminates the necessity of a space adapted to receive the lead line weld joined portion 55 therein; therefore, the total length of the magnetic circuit can be reduced. It is possible, thus, to generate a sufficient magnetic biasing force between the first core portion 33 and the anchor 35.

在传统的结构中，引线和端子端之间的引线焊接部55设置在磁路部分51的磁路的内部，这就增加了磁路的总长度，即， 通过引线焊接接合部分55的轴向尺寸，磁轭部分51.这将增加磁路的磁阻，这导致在第一芯部分33和第二芯部分33之间产生的磁偏置力的减小的问题。 在本发明中，引线焊接接合部分55设置在磁路部分的外侧，即磁轭部分51的外部。这消除了在其中容纳引线焊接接合部分55的空间的必要性。 因此，可以减小磁路的总长度。 因此，可以在第一芯部33和锚35之间产生足够的磁力作用力。
