    • A mounting unit for an electromagnetic contactor can prevent erroneous mounting of a non-mountable unit in a state in which a mountable unit is mounted on a case-side mounting portion, and a connection structure of an electromagnetic contactor uses the mounting unit. A mounting unit (3) for an electromagnetic contactor can be mounted on electromagnetic contactors (2a, 2b) having on a unit attaching portion (6b) a contactor-side mounting preventing portion (6f) that prevents mounting by engagement when a non-mountable unit, which cannot be mounted, is mounted. In the mounting unit (3), a unit main body (39) is provided with a mounting preventing transfer member (51) that forms a unit-side mounting preventing portion (54) that engages with a contactor-side mounting preventing portion (6f) when mounted on the electromagnetic contactors (2a, 2b) and prevents mounting of the non-mountable unit on a unit mounting portion (3g) onto which the non-mountable units (5a, 5b) are mounted.
    • 用于电磁接触器的安装单元可以防止在可安装单元安装在壳体侧安装部分上的状态下的不可安装单元的错误安装,并且电磁接触器的连接结构使用安装单元。 用于电磁接触器的安装单元(3)可以安装在具有单元附接部分(6b)上的电磁接触器(2a,2b)上,接触器侧安装防止部分(6f)防止当不可安装 安装无法安装的单元。 在安装单元(3)中,单元主体(39)设置有安装防止传递构件(51),其形成与接触器侧安装防止部(6f)接合的单元侧安装防止部(54) )安装在电磁接触器(2a,2b)上并且防止不可安装单元安装在安装有不可安装单元(5a,5b)的单元安装部分(3g)上。

    • The electromagnetic contactor enables a reliable return to a pole open position without increasing the spring force of a return spring. In an electromagnetic contactor, an electromagnetic device having an exciting coil and a contact mechanism having a return spring are disposed in parallel, and the electromagnetic device and contact mechanism are linked by a drive lever. The electromagnetic device has a polarized electromagnet having a magnetic circuit that includes a permanent magnet generating a suction force that moves the contact mechanism to a pole open position side when the exciting coil is not energized. The drive lever is fixed to either one of the electromagnetic device or contact mechanism and contacts with the other with no gap at least when the contact mechanism is moved to the pole open position side. The return force of the contact mechanism is covered by the suction force of the permanent magnet.
    • 电磁接触器能够可靠地返回到极开放位置,而不增加复位弹簧的弹簧力。 在电磁接触器中,具有励磁线圈的电磁装置和具有复位弹簧的接触机构平行设置,电磁装置和接触机构通过驱动杆连结。 电磁装置具有具有磁路的极化电磁体,该磁路包括永久磁铁,当励磁线圈未通电时,该永磁体产生将接触机构移动到极开位置侧的吸力。 驱动杆固定到电磁装置或接触机构中的任一个,并且至少当接触机构移动到极开位置侧时与另一个无接触。 接触机构的返回力被永久磁铁的吸力所覆盖。

    • First fitting portions (9a and 9b) and second fitting portions (9c and 9d) are arranged in a hook shape on the bottom (3a) of a housing to face each other. The first fitting portions are fittingly engaged to one rail edge (2a) of a rail (2) in the width direction and the second fitting portions are fittingly engaged to the other rail edge (2b) of the rail. A linear spring (10) bent in a mountain shape is disposed on the bottom of the housing. The linear spring elastically deforms to reduce the inclination angle of the mountain by contacting the end surface of the one rail edge engaged to the first fitting portions. The urging force of the linear spring urges the rail such that the other rail edge is pressed by the second fitting portions.
    • 第一装配部分(9a和9b)和第二装配部分(9c和9d)在壳体的底部(3a)上以钩状布置成彼此面对。 第一装配部分沿宽度方向与轨道(2)的一个轨道边缘(2a)适配地接合,并且第二装配部分适配地接合到轨道的另一个轨道边缘(2b)。 弯曲成山形的直线弹簧(10)设置在壳体的底部。 线性弹簧弹性变形以通过接合与第一装配部分接合的一个轨道边缘的端表面而减小山的倾斜角度。 线性弹簧的推动力促使轨道使得另一个轨道边缘被第二配合部分按压。
