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

There is provided a contact switching device which has high productivity and in which operation characteristics hardly vary. The contact switching device includes an electromagnetic unit (60), a holder (35), a movable shaft (43), a movable yoke (48), a movable contact piece (49) having movable contacts (49a) at both ends, fixed contacts (33a), and a fixed yoke (51). At the time of excitation of the electromagnetic unit (60), the movable shaft (43) moves to the holder (35) side along a direction of an axis center. A magnetic circuit is formed of the fixed yoke (51) and the movable yoke (48) due to a magnetic field generated by a current that flows into the movable contact piece (49) as a result of the movable contacts (49a) coming into contact with the fixed contacts (33a). The movable yoke (48) is then attracted to 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 ...
