直流接触器
摘要：
本发明涉及一种高压直流接触器，特别是涉及一种主触点工作电压高、防护等级要求高的高压直流接触器。直流接触器，其特征是，包括安装外罩(1)、壳体(2)、线圈组件(3)、衬筒(4)、铁心(5)、心杆(6)、返回弹簧(7)、绝缘垫板(8)、触头弹簧(9)、定位机构(10)、胶料(11)、灭弧罩(12)、静触头(13)、灭弧栅(14)、动触头(15)、卡圈(16)以及磁钢(17)；使用时，动触头(15)和静触头(13)错位接触，动触头(15)不完全覆盖静触头(13)。本发明通过简单的工艺，将非密封接触器制成密封接触器能有效的保护产品的线圈、主触头等，防护等级达IP66以上。
摘要（英）：

The invention relates to a high-voltage DC contactor, especially the high-voltage DC contactor with high working voltage of a main contact and high requirements for the protection level. The DC contactor is characterized by comprising an installation housing (1), a casing (2), a coil assembly (3), a bushing (4), an iron core (5), a core rod (6), a return spring (7), an insulated backing plate (8),a contact spring (9), a positioning mechanism (10), a rubber material (11), an arc extinguishing cover (12), a static contact (13), an arc extinguishing grid (14), a moving contact (15), a clamp ring(16) and magnetic steel (17). During use, the moving contact (15) makes offset contact with the static contact (13), and the moving contact (15) covers the static contact (13) incompletely. Via simple technologies, a non-sealing contactor is made into a sealing contactor to protect the coil, main contacts and the like of a product, and the protection level can reach IP66 and more.
