Abstract

PURPOSE:To save lavor and space required for performing maintenance checking or repairs and to decrease installment space for an electronic device by constructing such that an electronic circuit package and a power supply unit can be mounted and removed from the front of a case. CONSTITUTION:In order to get access to electronic circuit components such as an electronic circuit package 13 or a power supply unit 15 for the purpose of maintenance checking or repair if components in trouble, the electronic circuit package 13 is pulled out of a shelf 12 to the front of a case 11 while an output section 16 of the power supply unit 15 is removed from a power supply bus 18 on the front side of the case 11 and taken out to the front of the case 11. After the checking or repair as required is finished, the electronic circuit package 13 and the power supply unit 15 are reassembled from the front of the case 11. In this manner, the removal or reassembling of the electronic circuit package 13 and the power supply unit 15 can be performed only in front of the case 11 and hence more easily. Further, the space in front of the case 11 is sufficient for carrying out maintenance checking or repairs and therefore the installment space can be decreased substantially.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an electronic device in which an electronic circuit package is incorporated together with a power supply unit in a housing, and in particular to an electronic circuit that improves the workability of attaching and removing components into the housing. Regarding the internal structure of the frame.

[Conventional technology]

The internal structure of a conventional general electronic device will be explained with reference to FIG. FIG. 3 shows the planar arrangement of components within the electronic device.

A shelf 2 for holding shelf boards and the like is provided in a casing 1 with an open front face 1a, and a vertically elongated electronic circuit package 3 is attached to the shelf 2 so that it can be inserted and removed from the front side of the casing 1. . The electronic circuit package 3 is connected to a back panel 4 provided on the back side of the shelf 2. In addition, a power supply unit 5 is housed in the housing 1 from the rear by being arranged on the back side of the shelf 2, and the output section 6 of the power supply unit 5 is connected to the power receiving section 7 of the back panel 4 through a power supply bus 8 in the form of an abbreviation. connected via.

[Problem to be solved by the invention]

According to the internal structure of the electronic circuit described above, the insertion/removal direction of the electronic circuit package 3 and the mounting/removal direction of the power supply unit 5 are divided into two directions, front and rear with respect to the housing 1 . Therefore, when performing maintenance inspections or repairs when electronic components break down, it is necessary to take out the electronic circuit package 3 and the power supply unit 5 in the front and rear directions of the housing 10, which is time-consuming and requires a lot of work. This requires a work space, and if the electronic device is large and cannot be easily moved, there are problems such as the need for extra installation space in order to secure space for taking out parts in advance at the front and rear of the housing 1. was there.

The present invention has been made in view of the above circumstances, and it is an electronic device cabinet in which electronic components can be attached and detached only from the front side of the housing, reducing the number of intermediate works and reducing the space for work or installation. The purpose is to provide structure.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a power supply unit arranged in parallel with a shelf in a case with an open front, and allows the power supply unit and the electronic circuit package to be housed in the shelf to be connected from the front side of the case. It is removable and removable,
In addition, the output section of the power supply unit is connected to the connecting parts to the electronic circuit package on the front side of the casing, so that the electronic circuit package and the power supply unit can be attached only from the front of the casing.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view showing the internal structure of an electronic device, and FIG. 2 is a plan view.

In this embodiment, a shelf 12 is provided in a casing 11 with an open front surface 11a, disposed on the left side when viewed from the front, and a vertically elongated electronic circuit package 13 is placed inside the casing 11 in this shelf 12.
It is attached so that it can be inserted and removed from the front side. The electronic circuit package 13 is connected to a back panel 14 provided on the back side of the shelf 12. In addition, power supply unit 1
5 are provided in the casing 11 on the right side of the shelf 12 side by side, and are removable from the front side of the casing. The output section 16 of this power supply unit 15 is arranged on the front side of the housing 11, and the shelf 1
It is connected on the front side of the housing 11 via a power supply bus 18 and a contact piece 19, which are planar cross-shaped connecting parts along the back and right side surfaces of the housing 11. Note that a fan 20 for internal cooling is provided at the bottom of the shelf 12.

According to such a configuration, when performing maintenance and inspection of electronic circuit components such as the electronic circuit package 13 and the power supply unit 15, or repairs in case of failure, the electronic circuit package 1
3 from the shelf 12 to the front of the casing 11, and at the same time, remove the output section 16 of the power supply unit 15 from the power supply bus 18 on the front side of the casing 11, and remove it to the front of the casing 11. Moreover, after the work is completed, the electronic circuit package 13 and the power supply unit 15 may be assembled into the housing 11 from the front again. Therefore, the attachment/detachment work only needs to be done at the front of the casing 11, which simplifies the work and reduces the space required for maintenance, inspection, repairs, etc. The space in front of the body 11 is sufficient, and the installation space can be reduced, such as by being able to be installed on a wall.

In addition, in the embodiment, the power supply unit 1 is installed on the right side of the shelf 12.
5 is arranged in the above example, but any arrangement may be used as long as it can be installed and removed in parallel in the front of the housing, such as in reverse or in a vertical arrangement.

〔Effect of the invention〕

As described above, according to the internal structure of the electronic device according to the present invention, both the electronic circuit package and the power supply unit can be installed and removed from the front of the housing.
Not only can the work effort be reduced, but also the work space required for maintenance inspection and repair can be reduced, and the installation space for electronic devices can be reduced, among other excellent effects.
