Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of a terminal device.

In recent years, high-density mounting and downsizing of devices have been promoted, but accompanying this, assembling and adjustment of terminal devices,
A structure that is easy to maintain is desired.

[Conventional technology]

FIG. 2A is a side sectional view showing the structure of a conventional terminal device, and FIG. 2B is a plan view of FIG.

As shown in FIGS. 2 (a) and 2 (b), the terminal device 1 has a printed board 2
The base 3 on which the board is mounted and the front part of the base 3 (on the left side in the figure)
It is composed of a surface plate 5 attached with screws 4 and the like, an upper cover 6 and the like for covering the base plate 3.

An operation component 7 such as a switch is attached to the surface plate 5, a connection component 8 such as a connector is attached to the rear wall 3a of the base 3, and the upper cover 6 is easily attached to and detached from the base 3.

Wiring connection between each component and the printed board is performed by means of soldering, connector connection, or both after the above mounting is completed.

[Problems to be solved by the invention]

Because of the configuration as described above, it is necessary to disconnect the wiring connection before mounting the printed board 2 at the time of manufacture and disassembling it for adjustment and maintenance. Whenever the parts 7 and the connecting parts 8 are different,
Alternatively, it is necessary to prepare the surface plate 5 and the base 3 that are perforated according to the different arrangements, and standardization cannot be performed, resulting in a problem of cost increase.

[Means for solving problems]

The above problems are caused by a box-shaped base 3 ', a printed board 2 provided in the base 3', an upper cover 6 mounted on the base 3 ', and a front side of the base 3'. Surface plate 5 locked to
And an opening 3b is provided in the rear wall 3a 'of the base 3'to expose the connection component 10 mounted on the printed board 2 via the mounting metal fitting 8 to the rear surface side of the base 3'.
The printed board 2 so that the surface board 5 is detachably formed.
Is inserted into the opening 5a exposing the operation component 7 mounted on the front side of the base 3 ', and the locking holes 3c, 6a formed in the base 3'and the upper cover 6 with the operation component 7 mounted on the base 3'. This is solved by the terminal device according to the present invention in which the engaging piece 5b to be removed is provided on the surface plate 5.

[Action]

That is, by attaching the operating portion and the connecting portion in advance to the predetermined position of the printed board, performing the necessary wiring, and then mounting them on the base, and then attaching the surface plate having the predetermined opening, Wiring work after assembly is eliminated, assembly is easy, and wiring is not required when removing the printed board. It can be done easily by removing the surface board. The types and arrangements can be changed with a decorative board provided on the printed board, and the mechanical parts such as the surface board can be standardized.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 (a) to (c).

FIG. 1 (a) is a side sectional view showing the structure of the terminal device of the present invention,
The figure (b) is a plan view of the figure (a), and the figure (c) is a front view of the figure (b).

In the figure, 1'is a terminal device, 3'is a base plate, 5'is a surface plate, 9 and 10 are fittings, and 11 and 12 are decorative plates. The same portions are denoted by the same reference numerals throughout the drawings.

As shown in FIGS. 1 (a) and 1 (b), a terminal device 1'includes a board 3'on which a printed board 2 is mounted and a screw or a screw on the front part (left side in the drawing) of the board 3 '. It comprises a surface plate 5'which is attached by means such as fitting, an upper cover 6 for covering the base 3, and the like.

Operation parts 7 such as switches and connection parts 8 such as connectors
Is mounted at a predetermined position on the printed board 2 via mounting hardware 9 and 10.

In addition, the parts names, device names, and
Decorative plates 11 and 12 in which necessary items such as device numbers are described are attached.

Then, the wiring connection between each component and the printed board is performed by means of soldering or the like after the above-mentioned attachment is completed.

The printed board 2 thus mechanically and electrically connected is thus provided with the opening 3 provided in the rear wall 3a 'of the base 3'.
After inserting or exposing the connecting part 8 in b, it is fixed on the base 3 '.

After that, the locking piece 5b of the surface plate 5'having a predetermined opening 5a is engaged with the locking holes 6a, 3c provided in the base 3'and the upper cover 6 as shown in FIG. Install.

The surface plate 5'is made of, for example, plastic, and has an opening 5a having a predetermined size as shown in FIG.

Therefore, by performing the above assembly, as shown in (c) of the figure,
The decorative plate 11 of the operating component 7 is exposed by closing the entire surface of the opening 5a, while the decorative plate 12 of the connecting portion is the rear wall 3 although not shown.
Similarly, the entire surface of the opening 3b of a'is closed and exposed.

When the above work is completed, the upper cover 6 is covered and the assembly is completed.

[Effect of device]

As described above, by applying the structure of the present invention to the terminal device, the assembly and the removal of the printed board are facilitated, the assembly and maintenance are improved, and the mechanical parts such as the surface board are standardized. It is possible to improve the reliability and reduce the cost.
