Embodiment Construction

[0043] according to Figure 1 to Figure 17 The accompanying drawings describe the case where the contact switching device according to the embodiment of the present invention is applied to a sealed electromagnetic relay.

[0044] The sealed electromagnetic relay of this embodiment includes at least an electromagnet unit 60 , a holder 35 , a movable shaft 43 , a movable contact piece 49 , a movable yoke 48 , a pair of fixed contacts 33 a and a fixed yoke 51 . Specifically, as Figure 1 to Figure 5 As shown, the case 10 is assembled with the cover 20 to form a case, and the contact mechanism unit 30 and the electromagnet unit 60 are incorporated in the case.

[0045] Such as figure 2 As shown, the housing 10 is an insulating resin molding in a substantially rectangular box shape, and a set of notches 11 are formed on one side of the opening edge. In addition, the housing 10 is provided with a total of two pairs of locking holes 12 at both ends of the opening edge portions of...

Abstract

The invention provides a contact opening and closing device, which has high production efficiency and is less prone to deviations in operating characteristics. The contact opening and closing device has an electromagnet unit (60), a retainer (35), a movable shaft (43), a movable yoke (48), and a movable contact (49a) at both ends. A contact piece (49), a fixed contact (33a) and a fixed yoke (51). In addition, when the electromagnet unit (60) is excited, the movable shaft (43) moves toward the holder (35) in the axial direction, and the movable contact (49a) The magnetic field generated by the current flowing through the movable contact piece (49) in contact with the fixed contact (33a) is formed by the fixed yoke (51) and the movable yoke (48). loop, the movable yoke (48) is attracted by the fixed yoke (51).

Description

technical field [0001] The present invention relates to a contact switching device, in particular to a contact switching device suitable for a power load relay or an electromagnetic switch. Background technique [0002] Conventionally, as a contact opening and closing device, for example, Patent Document 1 Figure 5 As shown in (a), a pair of through-holes 61a are provided on the upper surface of the container 61 made of a heat-resistant material such as ceramics. Furthermore, the fixed terminals 33 and 33 are respectively inserted into the pair of said through-holes 61a, and are soldered. Furthermore, a yoke body 63 is fixed inside the upper surface of the container 61 located between the pair of fixed terminals 33 , 33 . The yoke body 63 has a substantially rectangular parallelepiped shape made of a magnetic material such as mild steel. [0003] Furthermore, when the movable contacts 34 , 34 provided on the movable contact 35 come into contact with the fixed contacts 32 ...
