Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a structure for mounting a plurality of different types of equipment units on an apparatus main body.

(Prior Art) For example, in electronic equipment such as various communication systems, various measurement systems, and various computer systems, a structure is known in which the entire system is configured by attaching various equipment units to the main body of the equipment by connecting connectors. In this type of system, the equipment unit is often constructed on a single printed circuit board, and a connector section (edge connector) constructed at the end of this printed circuit board is inserted into a connector attached to the main body of the device. The structure is such that it can be installed by

In the above-mentioned conventional structure, the connectors attached to the main body of the apparatus are usually of the same size for a plurality of equipment units, so that errors occur when installing the equipment units. In order to avoid this, conventionally, a notch was provided in the edge connector part at a different position for each equipment unit, and the position of the edge connector cut in the connector of the device body corresponded to the position of the edge connector of the equipment unit attached to the connector. Pins are provided at certain locations to prevent different types of equipment units from being attached.

(Problems to be Solved by the Invention) According to the above-mentioned conventional structure, it is necessary to fix pins in different positions to each of the plurality of connectors on the main body of the device, and when installing the system, etc. If the pin comes off due to impact on the device body, the decoy attachment prevention mechanism may not function. Also, if the number of contact pins in the connector becomes high density, it is recommended to make a notch in the edge connector part of the lint plate. There are various problems such as difficulty in

The present invention is proposed to solve the above-mentioned conventional problems, and aims to provide a device unit mounting structure that has a simple configuration and can completely prevent misplacement of device units.

(Means for Solving the Problem) For the above purpose, the present invention sets the connector position of the device main body to be different for each different type of device unit, and the edge connector of the device unit is set at the respective connector position of the device main body. The connector connection level between the device unit and the main body of the device can be set to be different for each different type of device unit, thereby making it impossible for the device unit to be installed in any position other than the predetermined position.

(Configuration of Embodiment) FIGS. 1 and 2 are a front view and a side view, respectively, showing essential parts of the structure of an embodiment of the present invention.

Note that FIG. 1 shows the device main body IC, and FIG. 2 shows the device main body and the equipment unit. In addition, in Fig. 2, the connectors on the main body of the device are shown slightly shifted for each connector for different models to make it easier to understand (in reality, they are fixed in the same horizontal direction), and The unit is shown in its state before being installed in the main body of the device, with slight deviations depending on the model.

In Figures 1 and 2, 1 to 7 are connectors on the main body of the device, and 8 is a printed board (so-called motherboard board, hereinafter referred to as a motherboard board) that fixes the connectors 1 to 7 and also makes electrical connections. ), 9 and 10 are provided above and below the connectors 1 to 7, respectively, and guide rails 11 and 12+d serve as guides when installing equipment units and support the equipment units.
A part of the frame of the main body (hereinafter referred to as the frame).

), 21 to 27 are equipment units.

As shown in Figure 1, ] connectors 1~ are motherboard B
above and parallel to each other and the equipment units 21-2
They are fixed at different fixing positions (heights) for each of the 7 models. That is, the dimensions a%blC and d from the bottom surface of the groove of the lower guide 9 to the lower end of each connection of the connector 1 are set to be different from each other.

Connector 2.3.4 (with the same dimensions)
Dimension b') and connector 5.6 (dimension C) are fitted with the same type of equipment unit 22, 23, 24 and equipment unit 25, 26 (each shown in an overlapping state in Fig. 2). be done.

In addition, the lower guide rail 9 and the upper guide rail IO
are fixed to frames 11 and 12 at equal intervals, respectively,
The interval between them is set to be the same for all connectors 1 to 7. This is because the device units 21 to 27 are all set to have the same dimensions (particularly, the dimensions in the height direction in the installed state are the same).

As shown in FIG. 2, the positions where the edge connector parts 21A to 27A of the device units 21 to 27 are formed are set differently for each model, and each corresponds to the position of the connectors 1 to 7. It is. That is, from the lower end of the equipment units 21 to 27, the respective edge connector portions 2
The dimensions es L gs h to the lower end of connectors 1A to 27A are different from each other, and each of the connectors 1 to 7A is different from the other.
The dimensions a, b, c, and d mentioned above are set to be the same. In addition, 49 units of the same model 22.23.24
It goes without saying that (dimension f) and 25.26 (dimension g) are set to be the same for each of the above dimensions.

(Operation of the embodiment) With the configuration described above, the equipment units 21 to 271
d. It can be installed only at the designated positions on the main body of the device. That is, even if the device unit 21 is to be installed in a position other than the normal position, for example, where the connector is fixed, the upper part of the edge connector part 21A will come into contact with the upper end of the connector 2, and the connector 2 will The edge connector section 21A cannot be inserted into the connection section of the connector.

(Other Embodiments) The embodiment described above is an example in which an edge connector is formed on the printed board of the equipment unit, but the connector of the device main body and a pair of connectors are fixed to the equipment unit to configure the connection part. Even in such a case, the present invention can be carried out by making the fixed position of the pair of connectors to the equipment unit different for each model.

In the above embodiments, a structure in which the equipment unit is mounted vertically is adopted, but it goes without saying that a structure in which the equipment unit is mounted horizontally is also possible.According to the present invention, as described in detail above, This is an extremely simple structure in which the IH of the connector is made different for different models, and there is no need for a special structure on the connector, and it is possible to reliably prevent equipment units from being incorrectly installed. You can enjoy the effects.
