Abstract

PURPOSE:To raise mounting efficiency of a housing and to obtain a device in which its floor area can be reduced, by selectively mounting a terminal mounting plate on any of both sides perpendicular to a front face, and securing unit containing cases and the plate to a supporting plate installed between crossbars arranged on the upper and lower parts of an outer housing. CONSTITUTION:An outer housing 1 is formed in a floor-fixed trestle structure. When a front cover 6 is removed, a printed board 2 for forming a main circuit and a unit case 3 for containing it are disposed. When a side cover 7 perpendicular thereto is removed, outer wire connecting terminals 4 for connecting wires out of the outer housing are arranged in parallel with the surface of the cover 7, and a connecting work is performed from the side. Since a directivity is generated in a device installation in the connection from the side, a terminal mounting plate 5 is, so as to eliminate it, formed in a structure to be mounted at both sides. This is a combination with cross levers 8 mounted on ceiling and bottom and a supporting plate 9 bridged between the ceiling and the bottom so that the case 3 and the plate 5 can be replaced in any of rightward and leftward directions so as not to limit the installation place of the device.

Description

[Detailed description of the invention] [Industrial field of application] This invention is applicable to electronic exchanges, etc., which have a large number of external connection lines.
It also relates to mounting structures in electrical equipment that require connection changes, etc.

[Conventional technology]

FIG. 8 is a perspective view showing an example of a conventional electronic exchange.

In the figure, 1 is the outer casing of the device, 2 is the main part of the device and is a printed circuit board with built-in electronic circuits, and 3 is the printed circuit board 2.
4 is an external line connection terminal that receives a line coming from outside the outer casing, 5 is a terminal mounting plate to which the external line connection terminal 4 is attached, and 6 is a front cover that can be removed for maintenance.

Next, the operation will be explained. The outer casing has an upright structure that is fixed to the floor, and when the front cover 6 is removed, the printed circuit board 2 that forms the main circuit and the external line connection terminal 4 that connects the wire from the outside are arranged on the same surface. , the connection of the line from outside is
This is done by removing the front cover 6.

[Problem to be solved by the invention]

The mounting structure of a conventional electronic exchange is as shown above, and there is a large dead space A on the back side of the terminal mounting plate.
The mounting efficiency of the casing was poor, it took up a lot of floor space, and it took a long time to install it in a small office.

This invention was made to solve the above-mentioned problems, and provides a device that can increase the mounting efficiency of the housing and reduce the floor space.

[Means to solve the problem]

In the electrical equipment mounting structure according to the present invention, a unit housing case and a terminal mounting plate are arranged on adjacent surfaces using a bridge bar and a support plate.

[Effect]

In the mounting structure configured as described above, the dead space that occurs on the back side of the conventional terminal mounting plate is eliminated, so the floor space is minimized, and the internal units can be rearranged, so that there are no restrictions on equipment installation. Therefore, it can be used effectively even in a small office.

〔Example〕

Hereinafter, an embodiment of the present invention will be explained with reference to FIG. 1,
FIG. 2 is a perspective view of an electronic exchange according to the present invention; FIG.
Figure 4 shows If-If line and 1\-IV in Figure 1, respectively.
5 and 6 are cross-sectional views taken along lines v--■ and --W in FIG. 2, respectively, and FIG. 7 is a plan view showing an example of the arrangement of the electronic exchange.

In the figure, numerals 1 to 6 indicate the same parts as those in FIG. ing. 7 is a side cover that needs to be opened and closed when connecting an outside line;
Reference numeral 8 denotes a bridge bar arranged on the ceiling and bottom of the outer casing 1 to which a support plate 9 is attached.
and the terminal mounting plate 5 is fixed.

Next, the operation will be explained. The outer casing has an upright structure that is fixed to the floor, and when the front cover 6 is removed, the printed circuit board 2 that forms the main circuit and the unit case 3 that houses it are located, and when the side cover 7 that is perpendicular to this is removed, this is visible. An external line connection terminal 4 for connecting a line from outside the outer casing is arranged parallel to the surface,
The connection work will be done from this aspect. As shown in FIG. 5, this connection from the side causes a directional problem in the installation of the equipment, so to solve this problem, the lug terminal mounting plate 5 is constructed so that it can be mounted on both sides. This allows the unit storage case 3 and the terminal mounting plate 5 to be replaced in either the left or right direction by combining the bridge bar 8 attached to the ceiling and bottom and the support plate 9 extending from the ceiling to the bottom. There are no restrictions on where the equipment can be installed.

Although the above embodiment has been described using an electronic exchange as an example, it is applicable to all similar devices that require work including connection to outside lines.

〔Effect of the invention〕

As described above, according to the present invention, the mounting efficiency is increased by L-shaped mounting, the floor space is minimized, and internal units can be rearranged to allow for no restrictions on equipment installation, making it effective for use in narrow offices. It has the effect of increasing utilization.
