大きくしてある。(Embodiment) FIGS. 1 to 4 show an embodiment of the present invention. Similarly to the conventional example, the mounting base 3 of this embodiment is also provided with a pair of insertion pieces 5 projecting from one end thereof, and the mounting piece 6 of the thermal relay 2 at the other end thereof.
Is formed. An upright engagement piece 11 is formed by bending on the inner side of each insertion piece 5 of the mounting base 3.
Protrusions 12 that project inward are formed on the inner surfaces of the engagement pieces 11 that face each other. Further, on both sides of the insertion piece 3, L-shaped elastic contact pieces 13 elastically contact the upper surface of the base 1a of the electromagnetic contactor 1.
One elastic contact piece 13 is formed wide, and an elliptical hole 17 is formed at the center. A mounting groove 14 into which the insertion piece 5 of the mounting base 3 is inserted is bored from the upper surface of the base portion 1a projecting to the lower side of the electromagnetic contactor 1, and the inner side surface of the mounting groove 14 is provided with the mounting base 3 of the mounting base 3. Locking protrusion that locks the protrusion 12
15 are formed. The base portion 1a between the locking projections 15 is cut out so that the side wall 20 of the mounting groove 14 in which the locking projections 15 are formed has elasticity. Further, an insertion groove 16 for inserting the outer edge of the insertion piece 5 is formed in the lower portion of the inner side surface on the outside of the mounting groove 14, and the insertion side of this insertion groove 16 is cut out in the vertical direction. It is designed for easy insertion. further,
A bulging portion that engages with the hole 17 of the elastic contact piece 13 in which the hole 17 is punched
18 is projectingly provided on the upper surface of the base portion 1a. As shown in FIG. 3, a pressing projection 19 for pressing the upper end of the engaging piece 11 with the lower surface is formed in the inner portion of the side surface inside the mounting groove 14, and the lower surface of the pressing projection 19 is formed. The width t 1 between the upper surface of the base 1a and the upper surface of the engaging piece 11 of the mounting base 3 and the lower surface of the elastic contact piece 13 of the mounting base 3 is larger than t 2 .

て係合突部15が削られることも少なくなる。The attachment base 3 is attached to the electromagnetic contactor 1 by inserting the insertion piece 5 of the attachment base 3 into the attachment groove 14 and pressing the attachment base 3 against the base portion 1a of the electromagnetic contactor 1. At this time, the outer edge of each insert piece 5 is inserted into the insertion groove 16
While being inserted into the inside, the engaging piece 11 is introduced into the inner part along the locking projection 15, and when the projection 12 gets over the locking projection 15, the projection 12 and the locking projection 15 are engaged. Then, the insertion piece 5 is prevented from coming off the mounting groove 14. Further, in this state, the elastic contact piece 13 elastically contacts the upper surface of the base portion 1a. When the projection 12 and the locking projection 15 are locked, the bulging portion 18 is fitted into the hole 17 of the one elastic contact piece 13 so that the mounting base 3 can also be detached by the elastic contact piece 13. To be prevented. Further, as described above, the width t 1 between the lower surface of the pressing projection 19 and the upper surface of the base 1a is larger than the width t 2 between the upper end surface of the engaging piece 11 of the mounting base 3 and the lower surface of the elastic contact piece 13. Therefore, even if there is a gap that facilitates the insertion between the insertion groove 16 and the insertion piece 5, the elastic contact piece 13 presses the upper surface of the base portion 1a, so that the entire insertion piece 5 is up. The upper surface of the engaging piece 11 is brought into contact with the lower surface of the pressing projection 19 to eliminate this gap, and rattling of the mounting base 3 is prevented. Further, the engaging piece is attached to one side of the inserting piece 5.
Since 11 is formed by bending, the bending strength of the insertion piece 5 can be increased, the deformation of the insertion piece 3 can be prevented, and therefore the conductor connected from the thermal relay 2 to the electromagnetic contactor 1 can be broken. Disappear. Further, since the locking projection 15 has elasticity, it is possible to remove the side wall when the mounting base 3 is removed.
The engagement state of the projection 12 of the mounting base 3 and the engagement projection 15 can be released by pushing 20 inward, so that the engagement projection 15 is less likely to be scraped by the projection 12.

きる効果がある。[Advantages of the Invention] As described above, the present invention has a mounting groove formed on the upper surface of the base of an electromagnetic contactor, and an engaging piece formed by bending on one side is formed and inserted and retained in the mounting groove. The insert piece is formed on the mounting base, and elastic contact pieces that elastically contact the upper surface of the base are formed on both sides of the insert piece. A protrusion is formed on the inner side surface of the mounting groove so that the protrusion is locked when it is inserted into the inside of the mounting groove. By forming the contact piece on the mounting base, the elastic contact piece lifts the insertion piece to eliminate the gap between the insertion piece and the mounting groove, preventing rattling of the mounting base and engaging with the insertion piece. By bending the part, the bending strength of the insert piece increases It is possible to prevent bending of one side, and by making the locking projections elastic, the locking projections escape when the mounting base is removed, so that the locking projections do not slip. There is.
