Embodiment Construction

[0039] according to Figure 1 to Figure 11 , an embodiment of the electromagnetic relay of the present invention will be described.

[0040] like Figure 1 to Figure 8 As shown, the electromagnetic contactor according to the embodiment of the present invention is roughly composed of a base 10, an electromagnet unit 20, a fixed contact terminal 30, a movable contact terminal 40 fixed with a movable contact piece unit 50 by riveting, and a rotating operating body 60. , an operation panel 70, a position limiting plate 80, and a cover 90.

[0041] The base 10 has a plane square box shape, such as image 3 As shown, a partition wall 11 is protruded from the bottom surface thereof, and a fitting step portion 11 a is formed on the upper side of the inward surface of the partition wall 11 . In addition, the base 10 is provided with a pair of terminal slits 12 a, 12 b on a side wall forming one internal space partitioned by the partition wall 11 . Further, a press-fit groove 13 for...

Abstract

The present invention provides an assembly structure of a contact terminal and an electromagnetic relay having the same, which can prevent poor contact and prevent deviations in operating characteristics. Therefore, the following assembly structure of the contact terminal is adopted, that is, the movable contact piece unit (50) is riveted and fixed on the riveting protrusion (41) provided at one end of the movable contact terminal (40), and the movable contact piece unit (50) is fixed by riveting. One end of the contact terminal is pressed into and supported by a press-fit groove (13) of the base (10). In particular, at least one pressing protrusion (41) higher than the riveting protrusion (41) after riveting protrudes from an edge portion of one end portion of the movable contact piece unit (50) opposite to the pressing direction. into the protrusion (54f).

Description

technical field [0001] The present invention relates to an assembly structure of a contact terminal, for example, an assembly structure of a movable contact terminal incorporated into an electromagnetic relay and riveted and fixed with a movable contact piece, and an electromagnetic relay provided therewith. Background technique [0002] Conventionally, as an assembly structure of a movable contact terminal to which a movable contact piece is caulked and fixed, for example, an electromagnetic relay in which one end of a first relay terminal 2 to which a contact spring 4 is caulked and fixed is press-fitted and supported is disclosed. in the press-fit groove of the housing (refer to Patent Document 1 figure 1 ). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Specification of US Patent No. 6661319 Contents of the invention [0006] The technical problem to be solved by the invention [0007] However, if figure 1 As shown, the above ...
