Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a power supply bus fixing tool, and more particularly to a power supply bus fixing tool used for fixing between a plurality of plate-shaped conductive power supply buses mounted in a housing of an electronic device or the like.

[0002]

[Prior Art]

 The power supply bus to which the power supply bus fixture of the present invention is applied is, for example, used as a power supply path when supplying a large amount of electric current and a low voltage power to a plurality of electronic circuits in an electronic device. In order to keep the electric resistance of the power supply path low, a plate-shaped material made of a conductive material is used as the power supply bus.

Since it is generally difficult to manufacture a power supply bus as a unit, the power supply bus is manufactured separately, and the power supply bus is assembled together with other electronic components in the housing. Is fixed by a fixture described later.

FIG. 4 (A) is a front view showing an example of a state in which the power supply buses 15 and 16 are fixed by using screws 20 as a conventional power supply bus fixture of this type, and FIG. 4 (A) is a side view of FIG.

The power feeding bus 15 is provided with a through hole 17 for fixing at a predetermined position, and the power feeding bus 16 has a female screw screwed into the screw 20 at a position corresponding to the through hole 17. Parts are provided. A spring washer 7 and a flat washer 8 are inserted into the screw 20. A screw 20 into which these washers 7 and 8 are inserted is screwed into a female screw portion of the power feeding bus 16 through a through hole 17 provided in the power feeding bus 15 to fix the power feeding bus 15 and 16 to each other. A plurality of screws 20 are generally used.

[0006]

When a screw, a flat washer, and a spring washer are used as the above-described conventional power supply bus fixture, fix a plurality of screws in which the flat washer and the spring washer are inserted from the tip. To be fixed by screwing them individually into the predetermined female screws of the power supply bus to be fixed, and when removing the power supply bus fixed in this way from the fixed partner power supply bus. Must be removed. When the screw is screwed or removed from the screw, the screw is accidentally dropped and lost.

[0007]

[Means for Solving the Problems]

 The power supply bus fixture of the present invention comprises a strip-shaped connecting plate and a plurality of screws, and a cylindrical portion having an outer diameter smaller than that of the screwed portion is formed in the longitudinal middle portion of the screws. The connecting plate penetrates a wide surface with an inner diameter that is larger than the outer diameter of the cylindrical portion of the screw and smaller than the outer diameter of the screw head and the threaded portion. A plurality of through-holes, and each of these through-holes and an edge of the connecting plate are individually connected to each other, and a groove whose width is slightly smaller than the outer diameter of the cylindrical portion of the screw is provided. The screws are loosely fitted in the through holes in the same direction in a one-to-one correspondence by inserting the columnar parts.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of a power supply bus fixture of the present invention, FIG. 2 is a plan view of the power supply bus fixture shown in FIG. 1, and FIG. 3 is a power supply bus fixture of FIG. FIG. 6 is a front view showing a state in which the power supply buses 5 and 6 are fixed by a fixing tool.

As shown in FIGS. 1 and 2, the power supply bus fixture of the present invention is a strip-shaped connecting plate 3 and a screw inserted into a through hole 9 provided in a wide surface of the connecting plate 3. 2 and a spring washer 7 inserted between the screw 2 and the connecting plate 3.

The through holes 9 are provided in the connecting plate 3 at appropriate intervals at three places, and the groove 4 is provided between a part of each through hole 9 and the edge of the connecting plate 3. There is. The screw 2 is provided with a cylindrical portion 1 having an outer diameter smaller than the outer diameter of the screwed portion and the head portion in the middle of the screwed portion and the head portion.

Further, the width of the groove 4 described above is made slightly smaller than the outer diameter of the cylindrical portion 1, and the diameter of the through hole 9 is larger than the outer diameter of the cylindrical portion 1 and the screw 2 is provided. It should be smaller than the outer diameter and the outer diameter of the head of screw 2.

After inserting the spring washer 7 into the cylindrical portion 1 of the screw 2, the cylindrical portion 1 of the screw 2 is inserted into the through hole 9 through the groove 4, and the cylindrical portion 1 of the screw 2 is inserted into the through hole 9. The screw 2 is rotatably held with respect to the connecting plate 3.

In this way, the screws 2 are loosely fitted in all of the plurality of through holes 9. FIG. 3 is a front view showing a state in which the power supply bus 5 and the power supply bus 6 are fixed by the power supply bus fixture shown in FIGS. 1 and 2, and the power supply bus 6 is attached to the connecting plate 3 in advance. A female screw to be screwed with the existing screw is provided at an appropriate position, and a through hole into which the screw 2 attached to the connecting plate 3 can be inserted is also provided at an appropriate position of the power supply bus 5 in advance. Female screw provided on the power feeding bus 6 by inserting the screw 2 attached to the connecting plate 3 into the through hole provided on the power feeding bus 5 such that the power feeding bus 5 is sandwiched between the plate 3 and the power feeding bus 6. It is screwed to and fixed between the power supply buses 5 and 6.

The spring washer 7 shown in the embodiment of FIGS. 1 and 2 may be used if necessary and may be omitted.

[0016]

[Effect of the device]

 As described above, in the power supply bus fixture of the present invention, the screw 2 is preliminarily attached to the connecting plate 3 so that the screw 2 can rotate. Therefore, the two power supply bus fixtures are fixed using such a power supply bus fixture. When doing so, or when removing the other power supply bus fixed to one power supply bus, there is an advantage that the screw 2 can be accidentally dropped and the risk of losing the screw can be eliminated.
