Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to securely fix a transparent cover that can be visually inspected to a terminal block, such as a closed type switchboard, in which a large number of control circuit cables and the like are connected in parallel with screws. Regarding what you did.

[0002]

2. Description of the Related Art In a terminal block such as a closed switchboard for connecting a large number of control circuit cables and the like in parallel, a transparent cover that can be visually inspected is generally provided on a panel body so that a connection portion cannot be touched. It is designed to be inserted and installed.

[0003]

In the above-mentioned structure, not only a lot of work is required for working the cover insertion portion of the board, but also the cover can be easily removed from the board by hand. There is a disadvantage that the so-called sealing effect is small.

[0004] In order to eliminate the above-mentioned disadvantages, the present invention provides:
It is an object of the present invention to provide a terminal board of a switchboard which can securely fix a transparent cover which can be visually inspected to a terminal board with screws without processing a board body.

[0005]

According to the present invention, in order to achieve the above object, a terminal block 1 is mounted on a support 2 with a pair of left and right screws 4 via a seat plate 3 at both ends of the seat plate 3. 3. The terminal cover 1 is bent toward both end surfaces thereof and its tip is bent outward in the horizontal direction, and a transparent cover 5 covering the upper surface of the terminal block 1 is attached to the horizontal bent portion 3a with screws 6. In the above description, the through hole 3b of the seat plate 3 through which the screw 4 for mounting the terminal block penetrates is formed as a long hole extending over the pair of right and left screws 4.

[0006]

Since the cover 5 is attached to the seat plate 3 which is fixedly fastened together with the terminal block 1 and the support 2 with the screws 6,
Not only does the work of processing the board and the like described in the prior art not only become unnecessary, but also the cover 5 is securely fixed and attached and a tool is required for removal, so that the so-called sealing effect of the terminal block connection portion can be increased. it can. Further, if the through hole 3b for the terminal block mounting screw of the seat plate 3 is made to be a long hole of an appropriate length, the seat plate 3 can be standardized in common with various types of terminal blocks 1 having a pair of left and right mounting screw intervals different from each other. .

[0007]

1 and 2 show an embodiment of the present invention. A terminal block 1 for connecting a large number of cables (not shown) in parallel is supported on a support 2 by a pair of right and left screws 4 via a seat plate 3. FIG. Fixedly mounted. Both ends of the seat plate 3 are bent toward both end surfaces of the terminal block 1, and the front end thereof is further bent outward in the horizontal direction. An insulative cover 5 made of a transparent plastic or the like that covers the upper surface of the terminal block 1 is fixedly attached to the horizontal bent portion 3 a with screws 6. The through hole 3b of the seat plate 3 shown in FIG.

According to the above-described embodiment, the cover 5 is attached to the seat plate 3 which is fixedly fastened to the terminal block 1 and the support 2 with the screws 6, so that the work of processing the board or the like described in the prior art can be performed. In addition to making it unnecessary, the cover 5 is securely fixed and attached, and a tool is required for removal, so that the so-called sealing effect of the terminal block connecting portion can be increased. Further, if the through hole 3b for the terminal block mounting screw of the seat plate 3 is made to be a long hole of an appropriate length, the seat plate 3 can be standardized in common with various types of terminal blocks 1 having a pair of left and right mounting screw intervals. .

[0009]

According to the present invention, in the terminal board of the switchboard, the transparent terminal board cover, which can be visually inspected, is attached to the seat plate fixedly fastened together with the terminal board and the support with screws. It is necessary to use a tool to securely attach and remove the cover without removing it, so the so-called sealing effect of the terminal block connection is increased.In addition, the through hole for the terminal block mounting screw on the seat plate is an elongated hole with an appropriate length. This has the effect that the seat plate can be standardized to be shared by many types of terminal blocks having a pair of left and right mounting screws with different intervals.
