Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio device and an electronic device, and more particularly to a module used for a medium-sized or large-sized radio device and an electronic device, and more particularly to a module case structure for improving wiring between modules. .

[0002]

2. Description of the Related Art Medium- and large-sized radios and electronic devices are modularized for each circuit function in consideration of ease of assembly and maintenance.

[0003] Conventionally, as a module structure of electronic equipment,
JP-A-5-191068 and JP-A-5-31387 disclose, but no particular reference is made to wiring between modules.

Hereinafter, a module structure of a conventional electronic device will be described with reference to FIG.

[0005] In order for the required functions to be exhibited, the wiring board 1
A circuit board 3 on which a wiring pattern is formed and various electronic components 2 are mounted to form a circuit is accommodated in a module case 4. Although the module itself is electrically connected to a motherboard or the like via a connector, a cable is often connected to the circuit board 3 from each side of another module depending on the circuit arrangement of the circuit board 3.

Conventionally, when a cable is connected to the circuit board 3, the cable 5 is routed so as to get over the module case 4 and is connected to a required position on the circuit board 3.

[0007]

With the module structure of the above-mentioned conventional electronic device, the module case 4
Since the cable 5 is routed so as to get over the module, it is necessary to secure a space for cable wiring between the adjacent module cases 4, and a wasteful space is increased in a housing for housing the module, and Becomes larger. In addition, since the cable 5 is directly connected to the circuit board 3, the routing of the cable 5 becomes messy, and it is difficult to confirm the connection destination of the cable 5 and liable to be erroneously wired. Further, when it becomes necessary to re-wire the cable 5 due to a change in specifications or the like, the wiring work is more complicated, requires attention of the operator, and places a heavy burden on the operator.

The present invention has been made in view of the above circumstances, and aims at simplifying wiring to a module, improving maintainability, reducing the space required for wiring, and reducing the size of electronic equipment.

[0009]

According to the present invention, a wiring groove is formed on an end face of a module case frame of a module for accommodating a circuit board, and an inner cutout and an outer cutout are formed at required portions of inner and outer walls of the wiring groove. The present invention relates to a module structure of an electronic device having a cutout.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

An embodiment of the present invention will be described with reference to FIG.

In FIG. 1, the same components as those shown in FIG. 4 are denoted by the same reference numerals.

The circuit board 3 has a circuit structure in which various electronic components 2 are mounted on a wiring board 1, and is housed in a module case 7.

The module case 7 includes a bottom plate 14 and a module case frame 15.

A wiring groove 8 is provided on the upper end surface of the module case frame 15 over the entire circumference, and a required position of the inner side wall 8a of the wiring groove 8, for example, one position in the center per side (in the drawing, shown). An internal cutout 9 is provided at two places in total. An outer cutout 10 is provided at a required position of the outer wall 8b of the wiring groove 8, for example, at each corner. Note that the inner cutout 9 and the outer cutout 10 may be located anywhere as long as they do not overlap.

The cable 5 connected to the circuit board 3 is fitted into the wiring groove 8 from the outer notch 10 and is routed in the wiring groove 8 so that the cable 5 at a position most suitable for connection of the cable 5 is connected. It is drawn into the module case 7 from the inner cutout 9 and connected to a required position of the circuit board 3.

Since the cable 5 is accommodated in the wiring groove 8, no extra space is required for wiring the cable 5. Therefore, it is also possible to arrange the adjacent module cases 7 in close contact with each other, thereby saving space.

Further, since the wiring groove 8 functions as a wiring duct, the wiring is not scattered, the wiring is good, and the outer cutout portion 10 passing through each connection destination is divided, so that erroneous wiring is eliminated.

The structure of the module case frame 15 may be a structure in which the wiring groove 8, the inner cutout 9, and the outer cutout 10 can be formed, and may be a molded product. May be used.

Next, FIG. 2 shows another embodiment.

In the other embodiment, the module case frame 15 is constituted by a plurality of partial frames 11.
A bolt hole 12 is formed in the partial frame 11 at a common position, preferably at a corner, and penetrates vertically.

The wiring groove 8 is formed at the upper end surface of each of the partial frames 11, an inner cutout 9 is formed at a required position on the inner wall 8a of the wiring groove 8, and a corner is formed at the corner of the outer wall 8b. An outer notch 10 is formed. By overlapping a plurality of the partial frames 11, the wiring grooves 8 are formed in a plurality of stages,
The cable 5 can be further finely divided for each connection destination, the identification of the cable 5 becomes easy, erroneous wiring can be prevented, and wiring routing can be simplified.

Of course, the partial frame 11 can be set to the minimum height required for the module case 7, and as shown in FIG.

When additional cable wiring is required due to a change in specifications or the like, wiring can be easily performed by further adding the partial frame 11, and the cable can be completely separated from the already wired cable 5. Reliable wiring can be performed with a simple operation without interference or erroneous recognition.

Furthermore, if the partial frame 11 is standardized and the module is changed by changing the number of stages of the partial frame 11, the common partial frame 11 can be used for all the electronic device modules. If the parts management becomes easy and it is manufactured by molding, the partial frame 11
The price of a single unit is extremely low, which contributes to a reduction in manufacturing costs.

By providing a plurality of the inner cutouts 9 on one side and changing the positions of the inner cutouts 9 used for each connection point, the workability is improved and the erroneous wiring is further reduced.

The wiring groove may be formed on the lower end surface of the case frame.

[0028]

As described above, according to the present invention, a wiring groove is formed on an end face of a module case frame of a module for accommodating a circuit board, and an inner notch is formed at a required portion of an inner wall and an outer wall of the wiring groove. Since the outer notch is formed, the cables connected to the circuit board are routed through the wiring groove, the inner notch, and the outer notch, so that the wiring to the module is simplified and the wiring can be easily identified. Therefore, the maintainability is improved, and the wiring is accommodated in the space occupied by the module, so that there is no need for an extra space for cable wiring, and excellent effects such as miniaturization of electronic equipment can be achieved.
