Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to the structure of an option console applied to a printed wiring board (hereinafter referred to as a module) on which electronic circuit components are mounted.

Description of the Prior Art Generally, an electronic device is constructed by arranging multiple stages of modules in a stacked manner in a housing.In maintenance such as testing and diagnosis of the device, a 7' bag interface cable is connected to one end of the module. However, in the conventional method described above, the cable between the card and the console does not serve as an antenna, and various (radiation, etc.)
Since it is more susceptible to noise, there is a risk that the circuits within the module may malfunction, and it is necessary to prepare special hardware for the mounting position of the console. Furthermore, when the length and route of the cable are taken into consideration, problems tend to occur in terms of cable processing, safety, etc.

FIG. 1 is a perspective view showing an implementation form of a conventionally used option console. In this mounting method, a plurality of cards 2 equipped with electronic circuit components 1 are connected to a connector 4.
In the unit functions (modules) mounted on the wiring board 3 interconnected through the module, the test 9 diagnosis of the module is carried out by transmitting signals taken out from the card 2 through the connector 5 and the cable 7 with the key 8, lamp 9, etc. This is performed by connecting to the console 6 and operating from the console side.

OBJECTS OF THE INVENTION The present invention has been made in order to cope with the conventional situation, and therefore, an object of the present invention is to incorporate an externally drawn interface cable into a console, and also to provide a module with ease of maintenance. The object of the present invention is to provide a new optional console that can eliminate the above-mentioned drawbacks by making the operation surface of the console rotatable by 90 degrees.

Regarding maintainability, since the module is generally mounted in a housing, when diagnosing the test scissors 9 on a console, the operating surface changes from the bottom to the top of the housing depending on the module.

Therefore, if the module is located at the bottom of the housing,
The operating surface of the console should face upward; conversely, when located at the top, the console operating surface must face sideways (front as seen from the maintenance person).

Structure of the Invention In order to achieve the above object, an optional console according to the present invention (a console used only during test 2 diagnosis and not normally used) is particularly applied to an LSI module that is made into a functional unit. The main feature is that it connects to the module by plug-in, and the plug-in part rotates 90 degrees (the operating surface rotates 90 degrees isometrically).
The main structure consists of a console main body that has been made smaller and lighter by applying LSI, flat display, touch panel type, etc., and an external interface rotary connector.

DETAILED DESCRIPTION OF THE INVENTION Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 2 shows the configuration of a module when LSI is promoted. In other words, when compared with the example of the module shown in FIG. 1, the change in the mounting form brought about by the shift to LSI is that one to several cards 2 loaded with electronic circuit components 1 are compared to the LSI package 11 shown in FIG. 2. However, in a similar comparison, wiring board 3 is opposed to wiring board 10. At this time, the wiring board 10 tends to be larger than the conventional card 2, even though it is implemented as an LSI, in order to integrate functions equivalent to those of the conventional card onto one wiring board 10. Note that 12 in FIG. 2 is a front plate necessary for function display, aesthetics, cooling, etc., and 21 is a console compatible connector on the wiring board 10 side.

Figure 3 shows the elements 10.11.12.21 explained in Figure 2.
This figure shows an example in which an option console 13 according to the present invention is mounted on an LSI module made up of the following. At this time, the front plate 12 becomes rotatable so as to be compatible with normal times and when an optional console is applied.

FIG. 4 shows an optional console structure that is rotatable through 90 degrees according to the present invention. To be more specific, the interface connector 14 is located at 90° as shown in FIGS.
° Rotate. In conjunction with the rotation of the connector 140, the console side metal fittings n, 23 can also be rotated as shown in the figure in order to attach them to the module side metal fittings 16 and 17 shown in FIG. Note that the shaded portion of the connector 14 in the figure corresponds to the surface corresponding to the module-side connector.

FIG. 5 is a diagram showing details of section B in FIG. 4.

The signal cable 5 taken out from the internal circuit of the console main body 13 is connected to the connector 14 through the inside of the connector support U.
connected to. The connector support 24 is rotated 90' through the support 24p as shown in direction C according to the requirements of the operation surface (input direction), and is inserted into the hole provided in the console body 13 with a screw (straddle semi-fixed). Clips 25 and 27 are fitted and fixed. .

FIGS. 6(a) and 6(b) are schematic diagrams showing an example of use to which the optional console according to the present invention is applied, in which two maintenance personnel test modules 1o mounted on a chassis path.

A) shows an example of a diagnosis being made. Figure 6 (
It can be seen from a) and (b) that the operation surface (direction A) of the console 13 changes as appropriate.

It should be noted that the embodiments of the present invention described above are merely illustrative, and it goes without saying that the present invention is not limited only by the embodiments described here.

As described in detail, the rotary optional console structure according to the present invention enables effective improvements in terms of electrical characteristics and maintenance operation by incorporating cables during maintenance such as test 1 diagnosis of electronic equipment a.
