DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay mounting structure for mounting a relay having a plurality of plate-shaped relay terminals to a relay mounting portion such as an electric junction box.

[0002]

2. Description of the Related Art FIG. 6 shows a relay 1 and a bus bar integrated terminal 3 to which a relay terminal 2 of the relay 1 is connected. In the figure, a relay 1 is formed of a box-shaped relay body 4 in which a coil, a contact and the like are built, and a plurality of plate-shaped relay terminals 2 protruding from the lower surface side of the relay body 4. .

On the other hand, a relay mounting portion 5 such as an electric junction box to which the relay 1 is mounted is provided with a bus bar integrated terminal portion 3 formed integrally with the bus bar.

When the relay 1 is mounted on the relay mounting portion 5, a relay terminal 6 is used to connect the plate-shaped bus bar integrated terminal portion 3 as well as the plate-shaped relay terminal 2. Therefore, there is a problem that the number of parts is large and the manufacturing cost is high.

Therefore, as shown in FIG. 7, a slit 7 is formed in the busbar-integrated terminal portion 3, and the relay terminal 2 is formed in the slit 7 so as to cross the busbar-integrated terminal portion 3.
A mounting structure has been proposed in which a cable is inserted and connected. In this structure, as shown in FIGS. 8A, 8B, and 8C, the bus bar integrated terminal portion 3 is positioned along the center line of the relay terminal 2 in the width direction. 3 is arranged on the relay mounting portion 5.

As shown in FIGS. 9 (a) and 9 (b), the relay terminal 2 has a relay terminal 2a connected to the coil side of the relay 1 and a relay terminal 2a having a longer width than the relay terminal 2a. There is a relay terminal 2b connected to the side. In the center of each of the relay terminals 2a and 2b in the width direction, a circular hole 8 is formed to penetrate.

However, in the structure in which the relay terminal 2 is inserted and connected into the slit 7 of the bus bar integrated terminal portion 3, since the round holes 8 are formed at the center in the width direction of the relay terminals 2a and 2b, the slit is formed. When the relay terminals 2a and 2b are inserted into the relay holes 7, the protrusions 9 and 9 of the slit 7 slide into the surface of the relay terminals 2a and 2b after the protrusions 9 and 9 are inserted into the round holes 8 and 8, respectively. Feeling. As a result, although the relay terminals 2a and 2b are not completely inserted into the slits 7, it is mistaken that the fitting has been completed, and a half-fitted state occurs.

In addition, since the convex portion 9 of the slit 7 is cut off at the edge of the round hole 8, there is a problem that the regular contact of the relay terminals 2 and 2 with the slit 7 is impaired.

Therefore, as shown in FIGS. 10 and 11, the busbar integrated terminal portion 3 is attached to the relay mounting portion 5 by the relay terminal 2.
It is conceivable to dispose the busbar integrated terminal portion 3 at a position shifted from the center in the width direction of the relay terminals 2a and 2b, that is, at a position offset from the center in the width direction of the relay terminals 2a and 2b. By offsetting the bus bar integrated terminal portion 3 from the center in the width direction of the relay terminal 2 in this way, the round holes 8 and 8 of the slit 7 do not interfere with the convex portion 9 of the slit 7, and the Problems such as fitting can be prevented.

[0010]

However, if the bus bar integrated terminal portion 3 is arranged at a position offset from the center in the width direction of the relay terminals 2a, 2b, the relay terminals 2a, 2b are connected to the bus bar as shown in FIG. When inserting the relay terminal 2a into the slit 7 of the integrated terminal portion 3, there is a difference in the insertion force between the left and right in the width direction of the relay terminals 2a, 2b.
There is a problem that occurs. As a result, when the relay 1 is mounted on the relay mounting portion 5, the relay 1 may be twisted and the relay terminals 2a and 2b may be damaged.

Accordingly, the present invention is directed to a relay which can be mounted without twisting when the relay is mounted on the relay mounting portion even if the bus bar integrated terminal portion is connected at a position shifted from the center in the width direction of the terminal of the relay. The purpose is to provide a mounting structure.

[0012]

In order to achieve the above object, according to the present invention, a relay having a relay body and a plurality of plate-like relay terminals protruding from the relay body is attached to a relay mounting portion. A relay mounting structure in which a relay terminal is inserted into and connected to a slit of a busbar body terminal portion provided, and is mounted on a relay mounting portion. The center of gravity is
Center or near the center of the relay body in plan view
The connection portion is arranged so as to overlap with the above.

[0013] In this relay mounting structure, the center of gravity of each insertion force of each connection portion between the relay terminal and the bus bar integrated terminal portion is determined by:
Center or near the center of the relay body in plan view
When the relay is mounted on the relay mounting part, if you press near the center of the upper surface of the relay body, a force is applied almost equally to each connection part, and a rotational moment may be generated in the relay body Absent. As a result, the relay does not pry on the relay mounting portion.

According to a second aspect of the present invention, in the first aspect of the present invention, at a position shifted from the center in the width direction of the relay terminal,
The busbar-integrated terminal is displaced from the center in the width direction of the relay terminal so that the relay terminal is inserted and connected into the slit of the busbar-integrated terminal.

In this relay mounting structure, the slit of the bus bar integrated terminal portion is provided at a position deviated from the center of the relay terminal in the width direction, so that even if a round hole is formed at the center of the relay terminal in the width direction. Does not interfere with round holes.

Further, even when the slit of the bus bar integrated terminal portion is displaced from the center of the relay terminal in the width direction, the center of gravity of the insertion force at the plurality of connection portions is in the center of the relay main body in plan view. Since they are overlapped, no rotational moment is generated in the relay body when the relay is mounted on the relay mounting portion, and no prying occurs.

The third aspect of the present invention is the first or second aspect.
Wherein the plurality of connection portions are arranged so as to be symmetric with respect to an axis passing through the center of the relay main body in plan view of the relay main body.

In this relay mounting structure, by arranging a plurality of connecting portions so as to be symmetrical with respect to an axis passing through the center of the relay body in plan view, the connecting portions are arranged on both sides of the shaft with good balance. Therefore, when the relay is mounted on the relay mounting portion, no rotational moment is generated in the relay body, and no prying occurs.

[0019]

18 are arranged.

That is, the center of gravity of the resultant force of the insertion force generated when the relay terminals 12, 12 of the connection portions 15, 17 are inserted into the slits of the bus bar integrated terminal portions 14, 14 connects the connection portions 15, 17. The center of gravity of the resultant force of the insertion forces, which is also on the line 20 and also occurs on the connecting parts 16, 18, is on the line 21 connecting the connecting parts 16, 18. The intersection of these lines 20 and 21 overlaps the center 19 of the relay main body 11.

Therefore, when the center 19 of the relay body 11 is pressed, a substantially equal force acts on each of the connection portions 15, 16, 17, and 18, and a biased force does not act on the relay body 11, so that No rotational moment is generated. As a result, no prying occurs in the relay main body 11.

As a result, stable contact can be ensured without damaging the relay terminal 12 or the bus bar integrated terminal portion.

Also, each of the connection parts 15, 16, 17, 18
Since a substantially uniform force is applied to the relay 10, no unnecessary force is required when the relay 10 is mounted on the relay mounting portion 13, and the insertion force can be reduced accordingly.
