[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bus bar fixing device.

[0002]

2. Description of the Related Art Conventionally, in order to prevent a bus bar housed in a bus bar housing groove provided on an insulating member from coming off and fixed, as shown in FIGS. 3 and 4, both bus bar housing grooves 21 provided on an insulating member 20 are provided. The protrusions 22 are formed at predetermined intervals on the edge, and after the bus bars 23 are disposed in the bus bar storage grooves 21, the protrusions 22 are crushed by heating and pressing to prevent the bus bars 23 from coming off.

[0003] In addition, the bus bar is connected to the bus bar in a longitudinal direction.
Bend the connection terminals provided on both sides of the part at right angles in two steps
First and second legs are formed and laminated with this busbar interposed
The laminate has a central spine that is continuous in the longitudinal direction,
A ridge that fits into the mountain-shaped recess of the subbar, and a peak of the busbar
A concave ridge for fitting the mold convex is provided, and on both sides of the central spine.
Surrounded by the provided eaves and the protruding partition wall on the front
Forming a large number of receiving terminal insertion parts,
To assemble the first busbar over the first laminate
Place the ridge on the center spine of this laminate
Cover with the joints and connection terminals , and place a second laminate on top of this
The first and second ridges of the first laminate are inserted into the first and second ridges of the laminate.
Insert the busbar and insert the end of the partition wall into the eaves of the first laminate
Part of the groove, and thus the bushing
No. 56-101874 assembled across the bar
Joint stocks are known.

[0004]

The problem to be solved by the invention is shown in FIGS.
The conventional device requires a device for heating and pressurizing the projections 22 provided on both edges of the bus bar housing groove 21 when the bus bar 23 housed in the bus bar housing groove 21 provided on the insulating member 20 is prevented from coming off and fixed. As a result, equipment costs increase,
In the process of forming the insulating member 20 or the insulating member 20
When the insulating member 20 is laminated, since the protrusion 22 breaks during the transportation of the sheet and the cost is high because the head of the protrusion 22 crushed by heating and pressing protrudes from the upper surface of the bus bar 23. However, there is a problem that a groove into which the head of the projection 22 fits must be provided on the back surface of the insulating member located in the upper layer.

[0005] Also, the joint model disclosed in the above utility model is disclosed.
The central spine, convex ridge, concave ridge and central spine
Eaves and partitions must be provided on both sides of the
Do not assemble with a number of bus bars sandwiched between many laminates
If the bus bar is not fixed, the bus bar is placed on one laminate
Since it cannot be fixed simply by placing it on the
If it is not easy to work quickly
There is a problem.

An object of the present invention is to solve the above-mentioned problems and to provide a bus bar fixing device which can fix a bus bar to an insulating plate easily, quickly and securely.

[0007]

Means for Solving the Problems To solve the above problems,
The bus bar fixing device of the present invention
A bar storage groove 2 is provided.
Fitting of a fixture perpendicular to the storage groove 2 and recessed below the bottom surface of the storage groove 2
A concave groove 3 is provided and accommodated in the busbar storage groove 2 on the upper surface of the insulating plate.
Fit into the fixture fitting groove 3 in the middle of the bus bar 5 to be stored
A concave bent portion 6 is formed, and the bus bar 5 is connected to an insulating plate.
The fitting groove is fitted in the bus bar storage groove 2 on the upper surface.
Bus bar fixing tool 7 on the concave bent portion 6 fitted in
Are fitted.

[0008]

The concave bent portion 6 formed on the bus bar 5 is connected to an insulating plate.
1 is perpendicular to the busbar storage groove 2 and is recessed below the bottom surface of the storage groove 2
This fixture is fitted into the fixture fitting concave groove 3
The bus bar 5 can be fixed to the insulating plate 1 only by fitting the bus bar fixing tool 7 into the fitting concave groove 3, and the assembling can be performed.
The bus bar 5 and the insulating plate 1 do not fall apart during the operation.

You.

[0011] 7 Ah in the bus bar fixture made of an insulating material
On both side surfaces of the busbar fixing member 7, locking projections 8 , 8 are provided for locking with locking holes 4, 4 provided on opposing side walls of the fixing member fitting concave groove 3 . Reference numeral 9 denotes a lightening hole for imparting a spring property to the bus bar contact surface 7a of the fixture 7.

The bus bar 5 housed in the bus bar housing groove 2 by the bus bar fixing device of the present invention configured as described above.
To prevent the busbar storage groove 2 from being pulled out, the concave bent portion 6 formed on the busbar 5 is fitted into the fixture fitting concave groove 3 in the middle of the busbar storage groove 2 as shown in FIG. The bus bar 5 is housed inside. Next, the fixing tool 7 is fitted into the fixing tool fitting concave groove 3, and the locking projections 8, 8 provided on both side surfaces of the fixing tool 7 are provided on the opposite wall surfaces of the fixing tool fitting concave groove 3. 4 and 4, the bus bar 5 housed in the bus bar housing groove 2 is prevented from falling off and fixed. In addition, as shown in FIG. 1, a plurality of bus bars 5 can be simultaneously fixed by one fixing tool 7.
