接触器1,2の底面側から挿入される。FIG. 5 shows a rail-mounted reversible electromagnetic contactor formed by connecting two electromagnetic contactors. The electromagnetic contactors 1 and 2 are integrated by a connector 4 with an interlock unit 3 interposed therebetween. Are linked to. Here, the interlock unit 3 is a mechanical interlock device for preventing simultaneous closing of two electromagnetic contactors. FIG. 6 shows the lower half of the reversible electromagnetic contactor of FIG. 5 in detail from the bottom side. Rail catching pieces 1a, 2a and sliders 1b, 2b are provided at the bottom of the electromagnetic contactors 1, 2. Has been. The electromagnetic contactors 1 and 2 are attached to the support rails (not shown) by hooking the rail hooking pieces 1a and 2a on the support rails with the sliders 1b and 2b retracted, and then pushing the sliders 1b and 2b. 1c and 2c are contact surfaces of the support rails. Engaging grooves 1d and 2d are provided on the opposite side surfaces of the electromagnetic contactors 1 and 2 respectively.
The connector 4 (FIG. 7), which is provided with each strip and has engaging pieces 4a on both sides corresponding to the engaging grooves 1d and 2d, is inserted between the electromagnetic contactors 1 and 2, and The two electromagnetic contactors 1 and 2 are connected by fitting the 4a into the engagement grooves 1d and 2d, respectively. Since the interlock unit 3 is sandwiched between the electromagnetic contactors 1 and 2, the connector 4 is inserted from the bottom side of the electromagnetic contactors 1 and 2.

を目的とするものである。In the above-described connection, since the force pressing the electromagnetic contactors 1 and 2 against the interlock unit 3 does not work in particular, the engagement portion of the interlock unit 3 with the electromagnetic contactors 1 and 2 is worn due to the vibration during the operation of the electromagnetic contactor. When the electromagnetic contactors 1 and 2 are turned on at the same time, the interlock unit 3 receives a force, and the electromagnetic contactors 1 and 2 escape to the outside as shown by the arrow in FIG. There was a problem that the relative position with the contactors 1 and 2 changed and the interlock function deteriorated. The present invention provides a coupling device for an electromagnetic contactor, in which a force for pressing the electromagnetic contactor against the interlock unit is generated at the time of coupling, thereby eliminating obstacles such as abrasion of the engaging portion of the interlock unit and deterioration of the interlock function. That is the purpose.

2との当接面積が増して連結力が向上している。An embodiment of the present invention will be described below with reference to the drawings. In addition, in FIGS. 1 to 4 showing an embodiment,
The same parts as those in FIGS. 1 to 7 are designated by the same reference numerals and the description thereof will be omitted. In FIG. 1, the connector 5 is a rear end side (upper side in FIG. 1).
The width dimension from the front end side is tapered in the width direction, and the width dimension B on the rear end side is set to be larger than the width dimension A on the front end side. The electromagnetic contactors 1 and 2 are connected by inserting the connector 5 between the electromagnetic contactors 1 and 2 from the narrow end and fitting the engaging pieces 5a on both side faces into the engaging grooves 1d and 2d. . At that time, the side surface 5b of the connector 5 comes into contact with the side surfaces of the electromagnetic contactors 1 and 2, but since the connector 5 has a larger width dimension as it comes closer to the rear end side, the electromagnetic contactors 1 and 2 are wedge-shaped. As shown by the arrow in FIG. 4, the bottom side is opened and the upper side is pressed by the interlock unit 3 under the rotational force of approaching each other. This prevents the electromagnetic contactors 1 and 2 from escaping to the outside during operation. FIG. 2 shows another embodiment. In this case, the connector 6
A wedge-shaped projection 6b is partially provided on the side surface on the rear end side with the engaging piece 6a interposed therebetween. As a result, the width dimension B on the rear end side is larger than the width dimension A on the front end side.
When the connector 6 is inserted between the electromagnetic contactors 1 and 2, the projection 6b on the rear end side abuts the side surface of the electromagnetic contactors 1 and 2, and the same operation as in the case of FIG. 1 is performed. FIG. 3 shows still another embodiment, in which the extension portions 7b tapered in the width direction are provided in front of and behind the rear end side of the connector 7, avoiding the support rails, and the width dimension B of the extension portion 7b is It is larger than the width dimension A. Reference numeral 7a is an engagement piece that engages with the engagement grooves 1d and 2d. In this case, the same effect can be obtained, and the electromagnetic contactor1,
The contact area with 2 increases and the connecting force improves.
