[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed structure for a coil lead terminal of a coil used in an electromagnetic contactor or the like.

[0002]

2. Description of the Related Art Japanese Utility Model Application No. 61-35717 proposed by the present applicant has a structure of pushing a coil terminal plate from above by a conventional coil terminal plate fixing method.

As shown in FIG. 6, when the terminal plate 21 is pushed into the terminal portion 22 from above by using an automatic machine, the terminal plate 21 has an inverted L-shape and is oblique to the wall 23 and the holding portion 24. There is a surface that cannot be fixed to the smooth because it tends to enter, and the terminal portions 22 are diagonally opposite to each other with respect to the coil 25, and two terminal portions are used at a time by using an automatic machine.
When fixing the terminal board 21 to the terminal 22 , there is a problem that it takes time to finely adjust the positioning.

[0003]

SUMMARY OF THE INVENTION As described above, there is a need to devise a coil terminal structure which improves workability when fixing the terminal plate 21 to the terminal portion 22 using an automatic machine.

[0004]

The present invention has a structure in which two terminal portions 10 formed in the same direction of a coil 12 are installed, and the shape of the terminal plate 1 is a rectangular shape symmetrical with respect to the center line in the direction of the wall 11. The bent portion 4 is formed at the end of the terminal plate 1, and the bent portion projection 4a is provided inside the bent portion of the bent portion 4 for press-fitting into the groove 14a. Therefore, the terminal plate projection 6 has a structure in which the terminal plate projection 6 is fitted and fixed to the projection 14b, and the corners that form the terminal plate projection 6 for fitting into the projection 14 are provided. When the hole 3 is formed symmetrically with respect to the center line in the direction of the wall 11, when the terminal board 1 is inserted into the protrusion 14 at the center of the terminal portion 10 from above by using an automatic machine, On the other hand, a structure is provided in which a force is applied evenly to the left and right to allow smooth insertion.

[0005]

[Advantage of the Invention] Using an automatic machine, the square hole 3 of the terminal plate 1 is inserted into the projecting portion 14 at the center of the terminal portion 10 from above.
Since the force is applied evenly to the left and right with respect to the center line when it is inserted, it can be smoothly inserted and can be fixed to the terminal portion 10. Since the terminal portion 10 is installed in the same direction as the coil 12, it is an automatic machine. When the terminal plate 1 is fixed to the two terminal portions 10 at once by using, the workability can be improved such as the positioning becomes simple.

Embodiment 10 is a terminal portion, 11b is a wall, 12 is a coil,
12a is a flange part and has a structure in which two terminal parts 10 are installed in the same direction, and 11, 11a are walls for preventing the terminal plate 1 from moving when fixing the terminal plate 1 to the terminal part 10 with the screw 8. Is. The wall 11 is formed inside the coil 12,
The wall 11 a is formed outside the coil 12. Wall 11 wall 1
It is continuous to the terminal portion 10 through 1b. By forming the walls 11 and 11a on both sides of the terminal board 1, the tightening strength of the screw 8 is also strengthened. Reference numeral 11c is a right-angled wall which is continuous with the wall 11 and has a wall 11b interposed therebetween. Reference numeral 9 is a terminal fixing portion, 14 is a protruding portion, 14a is a groove, and 14b is a protruding portion.
The protrusion 14 has a trapezoidal shape and is fitted in and fixed to the terminal plate protrusion 6 to form an inward protrusion 14b in the direction of the wall 11a. The groove 14a is the protrusion 14
It is formed in a continuous shape downward in the direction of the terminal portion 10 .
Reference numeral 13 denotes a protrusion, which is formed on the protrusion 14 side of the terminal 10 so as to be fitted and fixed to the locking hole locking portion 5a.

1 is a terminal plate, 2 is a screw hole, 3 is a square hole, 4 is a bent portion, 4a is a bent portion projection, 5 is a locking hole, 5a is a locking hole locking portion, and 6 is a terminal plate. The protrusions 17a and 17b are end portions, the terminal plate 1 is rectangular in shape, has a screw hole 2 at the center of one end, and has a square hole 3 that forms a terminal plate protrusion 6 for fixing to the protrusion 14. Locking hole which is configured symmetrically with respect to the center line in 11 directions, forms a bent portion 4 at the end of the terminal plate 1, and forms a locking hole locking portion 5a over the bent portion of the bent portion 4. Make up 5. The bent portion 4 has a shape that is narrower than the width of the portion of the terminal plate 1 where the screw hole 2 is provided, and one end portion 17a for fixing with the wall 11b and the other end coil portion on the other side. An end 17b is formed for soldering with the winding 16. Groove 14a extending toward the inside of the bent portion of bent portion 4
In order to press-fit the bent portion projection 4a to the projection portion 13, the locking hole locking portion 5a is formed at the bent portion of the locking hole 5 for fitting and fixing.

The method of mounting the terminal board 1 on the terminal portion 10 is as follows.

[Fig. 5] As shown in Fig. 5 (a), the protrusion 13 has an L
The outer sides of the character shape are in contact with each other, and pressure is applied in the direction of the arrow so that the square hole 3 enters the protruding portion 14, and the square hole 3 is inserted from above. Further pressurizing the terminal board 1 from above

FIG. 5 (b) shows that the terminal plate protrusion 6 has a protrusion 14
The bent portion 4 is press-fitted into the protrusion 13 and the groove 14a. Further pressurizing the terminal board 1 from above

As shown in FIG. 5 (c), the terminal plate protrusion 6 has a protrusion 14
It is fixedly attached to b, and the engaging portion 5a of the engaging hole is the protrusion 13
The terminal plate 1 is fixed to the terminal portion 10 in such a manner that the bent portion projection 4a is press-fitted into the groove 14a.

[0009]

When the terminal plate 1 is fixed to the terminal portion 10 from above by using an automatic machine, the terminal plate 1 can easily enter the walls 11 and 11a at a right angle, and the terminal portion 10 can be placed in the same direction of the coil 12. Since it was installed in the
When the terminal plate 1 is fixed to the terminal 10 from above, the workability can be improved by, for example, simplifying the positioning.
