Abstract

PROBLEM TO BE SOLVED: To prevent a test terminal from protruding to the outside of a body of equipment also prevent wrong connection of a testing cable, by receiving a stud type test terminal in an inner side receiving space in the body of equipment except at testing time, and drawing out the test terminal from the receiving space by turning a turn plate at testing time. SOLUTION: A through hole 15 is formed in a body of equipment 1 receiving an equipment, a cover 6 is provided inside the through hole 15, a receiving space 14 receiving a stud type test terminal 2 is formed between the cover 6 and the body of equipment 1, also an opening part 7 is formed in the cover 6, a turn plate 8 is turnably mounted in the body of equipment 1. The turn plate 8 is turned in the receiving space 14, so that the opening part 7 or the through hole 15 can be selectively closed. When the test terminal 2 is not used, the turn plate 8 is left as placed in a condition closing the opening part 7. In the case of using the test terminal 2, it is drawn out to outside the body of equipment 1 through the through hole 15 from the receiving space 14, so as to close the through hole 15 by the turn plate 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switchboard and has an improved test terminal mounting structure.

[0002]

2. Description of the Related Art A stud type test terminal is provided on a switchboard to test the value of voltage or current. As shown in FIG. 3, the stud-type test terminal 2 is attached by penetrating the housing 1 that constitutes the switchboard. And the stud type test terminal 2
A cable 3 is connected to the inside of the housing 1 at. A knob portion 2a for sandwiching and connecting a test cable (shown by a virtual line) is provided outside the housing 1 in the stud type test terminal 2. When two test cables are to be connected, the stud-type test terminals 2 are arranged side by side and attached to the housing 1, and are connected to each other via the conductor 5. In addition, 4 is an insulating member for preventing an electric shock accident.

[0003]

However, since the stud type test terminal projects to the outside of the switchboard, it is an obstacle to work and the like.

[0004] Therefore, an object of the present invention is to provide a switchboard which solves the above problems.

[0005]

In order to achieve such an object, the structure of the invention according to claim 1 is such that a cover is attached to the inside of a housing for accommodating a test terminal for connecting a test cable. To form an accommodating space, a pivot plate for selectively closing the opening and the through hole formed in the cover and the housing is rotatably provided, and the test cable is provided when the opening is closed. It is characterized in that the test terminal is attached by penetrating through the rotary plate so that the connecting portion for connection is located in the accommodation space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. Since the present embodiment is an improvement of a part of the conventional switchboard, the same parts as those of the conventional one are designated by the same reference numerals, and the description thereof will be omitted. Only different parts will be described.

The structure of the switchboard according to the present invention is shown in FIG. As shown in the figure, a rectangular through hole 15 is formed in the housing 1, and a cover 6 is provided inside the housing 1 to form an accommodation space with the portion of the housing 1 in which the through hole 15 is formed. It is provided. The cover 6 is attached to the housing 1 so as to cover 5 of the 6 surfaces other than the housing 1 side, and a rectangular opening is formed on a surface of the surface perpendicular to the housing 1 that is long in the vertical direction. The part 7 is formed.

A rotating plate 8 is rotatably attached to the housing 1 via a hinge 9 so that the through hole 15 or the opening 7 can be selectively closed. A spacer 10 is provided between the hinge 9 and the housing 1, and magnets 12 and 11 are fixed inside the through hole 15 and the opening 7 for fixing the rotating plate 8.

The stud type test terminal 2 is attached to the center of the rotary plate 8 so as to penetrate the rotary plate 8, and when the rotary plate 8 closes the opening 7, the test cable for the stud type test terminal 2 is attached. The knob portion 2a for mounting is located in the accommodation space 14. Besides, a handle 13 for opening and closing the rotating plate 8 is provided.

Next, the operation of such a switchboard will be described. When the stud type test terminal 2 is not used, the rotating plate 8 keeps the opening 7 closed as shown in FIG. Since the stud type test terminal 2 is housed in the housing space 14,
No one touches the stud type test terminal 2 when the switchboard is being transported to the site or when a person passes through the front side of the switchboard after the site installation.

When using the stud type test terminal 2,
Grasp the handle 13 in the accommodation space 14 and pull it out of the housing 1. Then, as shown in FIG.
Then, the rotating plate 8 is attracted to the magnet 12.
Next, a test cable is connected to the stud-shaped test terminal 2 that has been exposed to the outside of the housing 1.

In this embodiment, a single stud type test terminal is attached to the rotary plate, but two or three stud type test terminals may be attached as in the conventional case.

[0013]

As can be seen from the above description, according to the switchboard of the present invention, the test terminals are housed in the housing space inside the housing except during the test, so that the test terminals do not come into contact with each other and are safe. is there. In addition, since the person does not collide with the test terminal during transportation of the switchboard or after installation, there is no risk of damage. Then, during the test, the rotating plate is rotated to pull out the test terminal from the accommodation space, so that the test terminal to be used from now on is confirmed, and erroneous connection of the test cable is prevented.
