[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device for electric equipment.

[0002]

2. Description of the Related Art FIGS. 7 to 9 show an example of a conventional terminal device. FIG. 7 is a side view, FIG. 8 is a plan view, and FIG. 9 is a front view. 7 to 9, the terminal device is attached to the electric device 1 , and a plurality of terminals are provided on the terminal block 2 in which two terminals 2A and 2B are arranged in parallel in FIGS. And a terminal cover 3 for covering the exposed charged portions of the terminals 2A and 2B. The terminal cover 3 is attached to the terminal block 2 by mounting screws 3A.
Fixed to In FIG. 8, holes 3A and 3B provided in the cover 3 face the terminals 2A and 2B, respectively, and a charging rod (not shown) is inserted through these holes to check the charged state of the terminals. It is.

[0003]

In the terminal device described above, the terminal cover is fixed to the terminal block 2 by mounting screws. Therefore, each time the terminal cover is mounted or removed, the mounting screws are required. There is a problem that it is necessary to attach and detach by turning, and the operation is complicated. SUMMARY OF THE INVENTION It is an object of the present invention to provide a terminal device in which attachment and detachment of a terminal cover are simple and can be securely fixed.

[0004]

Means for Solving the Problems] To achieve the foregoing objects, the present invention includes two terminals having different widths sizes are arranged in parallel, between which terminals are partitioned by an inner wall this 2
In a terminal device including a terminal block in which both sides of each of the terminals and the outside are partitioned by side walls, and a terminal cover that covers an exposed charged portion of these terminals, the terminal covers are respectively provided in a downward direction. A vertical holding plate having a downward semi-arrowhead projection on both sides of its end,
It has a front-rear direction pressing angular convex part and a left-right pressing plate made of a plate provided on each side of the terminal cover, and the terminal block is provided on both sides of the vertical pressing plate provided on the inner wall. A vertical fitting groove that fits into one of the half arrowhead-shaped projections, a front-rear fitting groove that fits in the front-rear pressing angular projection, and a pair of side walls that fit in the left-right pressing plate. And a left-right fitting portion.

[0005]

When the terminal cover of the present invention is pushed downward, the semi-arrow-like projection on the side surface of the vertical holding plate moves laterally due to the lateral bending of the vertical holding plate, and then moves in the vertical direction of the terminal block. It falls into the fitting groove and fits. At the same time, the front-rear direction pressing angular projection is fitted into the front-rear direction fitting groove, and the left-right direction pressing plate is fitted into the left-right direction fitting portion. In this way, the three directions of up and down, front and rear, and left and right respectively correspond to the semi-arrow-shaped projections of the up and down holding plate and the up and down fitting groove, the up and down angular holding convex and the up and down fitting groove, and the right and left holding plate. Since it is fixed by the left-right fitting portion, it is securely fixed. Ma
Also, two terminals with different width dimensions are arranged in parallel
The terminal cover attached to the terminal block has multiple terminals
Are arranged in a row and these terminals are separated by an inner wall.
It can also be attached to terminal blocks.

[0006]

For removing the terminal cover, for example, a vertical pressing plate is bent by a screwdriver or the like, and the semi-arrow-shaped protrusion on this side is removed from the vertical fitting groove so as to be pulled upward.

[0008]

1 to 3 show one embodiment of a terminal device according to the present invention. FIG. 1 is a side view, FIG. 2 is a plan view, and FIG. 3 is a front view. 1 to 3, a terminal device is attached to an electric device 1, and a plurality of terminals, a terminal block 2 in which two terminals 2 </ b> A and 2 </ b> B are arranged in parallel in FIGS. , 2B and a terminal cover 3 for covering the exposed charging portion. FIG. 4 shows details of the terminal cover 3 of FIG.
4A is a side view, FIG. 4B is a plan view, and FIG. 4C is a front view. As shown in FIG. 4, the terminal cover 3 is provided with a downwardly extending semi-arrow-shaped projection 31A, 31B on each side surface of an end portion provided in a downward direction.
A right-and-left pressing plate 3 composed of front and rear pressing angular projections 32 and plates 33A and 33B provided on both sides of the terminal cover.
3 is provided. 5A and 5B show details of the terminal block 2 in FIG. 4, FIG. 5A is a plan view, and FIG. 5B is a front view. FIG.
As shown in (2), the terminals 2A and 2B arranged in parallel are separated from each other by an inner wall 2C.
Side walls 2D, 2B are provided between both sides of A, 2B and the outside.
Partitioned by E. The vertical fitting groove 21 and the front-rear pressing angular projection 32 that fit into the inner wall 2C of the semi-arrow-shaped projection 31A of the vertical pressing plate 31 of the terminal cover 3 on the terminal cover 3.
The two side walls 2D and 2E are left-right fitting portions 23 fitted to the left-right pressing plate 33.

When attaching the terminal cover 3 to the terminal block 2, the terminal cover is pushed down. Then, the semi-arrow-shaped projection 31A on the side surface of the vertical pressing plate 31 of the terminal cover 3 moves in the horizontal direction due to the horizontal bending of the vertical pressing plate 31, and then the vertical fitting groove 2 of the terminal block.
1 fits down. At the same time, the front-rear direction pressing angular projection 32 is inserted into the front-rear direction fitting groove 22 and the left-right direction pressing plate 33.
Are fitted into the left and right fitting portions 23, respectively. In this way, the three directions of up, down, front and rear, and left and right are the up and down direction holding plate 31.
Are fixed by the half arrowhead-shaped projection 31A and the vertical fitting groove 21, the front-rearward holding angular convex part 32 and the front-rearward fitting groove 22, the left-right pressing plate 33 and the left-right fitting part 23, respectively. Fixed to

In the case where two terminals having different widths d ₁ and d ₂ are arranged in parallel as shown in FIG. 3, the position of the inner wall 2C separating these terminals is plural. Deviates from the center line C, and in particular, if the arrangement order of these terminals is different, the terminals deviate from each other in the opposite direction to the center line C. In this case, semi-arrow-like projections of the vertical pressing plate 31 are provided on both side surfaces (FIGS. In FIG. 3, the arrowhead-like projections are provided on both side surfaces of the vertical holding plate 31 as indicated by 31A and 31B), and one of the arrowhead-like projections 31A and 31B on both side surfaces is In FIGS. 1 to 3, the terminal cover having the same structure is used regardless of the arrangement order of the terminals by fitting the half arrowhead-shaped projection 31 </ b> A into the vertical fitting groove 21 provided on the inner wall 2 </ b> C. be able to. Such a terminal device in which two terminals having different width dimensions are arranged in parallel, and in which the arrangement order of the terminals is different, is provided on the left and right sides of the electric device 1 as shown in FIG. A terminal device 11 on the power supply side and a terminal device 12 on the load side are provided, and as shown in FIG. 6B, the terminal arrangement for the main circuit 2B having a large width and the terminal width having a small terminal width are shown on the same side surface. It is often found in laminated electrical equipment provided with the auxiliary circuit terminal 2A, and the effect of using a terminal cover having the same structure for these terminal devices is great.

The terminal cover 3 is detached by, for example, bending the vertical holding plate 31 with a screwdriver or the like so that the half arrowhead-like projection 31A (31B) on the side surface is removed from the vertical fitting groove 21 and pulled up. I do.
