Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an electronic device such as a personal computer, in which an optional package mounting structure is provided for each user to add a function in addition to the standard function of the device. Regarding

[Prior Art] Conventionally, in this type of mounting structure, as shown in FIG. 3 and FIG. 4, a cage 2 is built in an apparatus main body 1, and an optional package 3 is mounted in the cage 2. . The option package 3 has a male card edge connector 4 attached to one end thereof.
Is engaged with the female card edge connector 6 on the backboard 5 arranged in the back of the cage 2 to electrically connect and fix the option package 3.
A plurality of female card edge connectors 6 are arranged on the backboard 5 at regular intervals so that a plurality of option packages 3 can be mounted.

[Problems to be solved by the device]

By the way, when the high performance of the option package becomes necessary due to the market demand, the number of signal input / output terminals of the option package also increases with the high performance, and the number of connector terminals of the conventional option package becomes insufficient. A connector with a large number of terminals is required. However, in the conventional mounting structure, only the connectors with a small number of terminals are attached to the OA devices that are widely used in the market, so that it is not possible to mount an option package with a connector with a large number of terminals, and the There was a problem that it could not meet the needs of.

An object of the present invention is to provide a package mounting structure that solves the above problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the package mounting structure according to the present invention is a mounting structure of an option package mounted in an OA device, wherein a backboard provided in a mounting cage of the option package and a backboard provided on the backboard. A set of two types of board connectors with different numbers of poles alternately arranged at the same interval, a set of two types of option packages, and one of the board connectors that forms the set. A guide that holds the two optional packages that form the group by guiding them together at the insertion height position of the one optional package that forms the group, and an extension line on the edge of the one optional package that forms the group. A first package connector provided along the first package connector for removably engaging the package with the one board connector of the set. And the other option package forming the set, which is provided so as to project laterally in the lateral direction by the mounting pitch between the board connectors forming the set, and the other option package being held by the guide. And a second package connector that detachably engages with the other board connector of the set.

〔Example〕

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

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view of the same.

In the figure, the backboard 5 is fastened to the rear of the cage 2 mounted on the OA equipment with the screw 7, and two types of female board connectors 6 and 10 having different numbers of poles are alternately arranged on the backboard 5 at the same interval. Arrange a plurality in the direction. Here, the adjacent female board connectors 6, 10 form a set, and the connectors 6, 10
The two optional packages 3 and 8 having the same width are engaged with each other.

In addition, two types of option packages 3 and 8 that form a set are shared by the inner walls of the cage 2 which are engaged with one of the board connectors 6 that form a set, and are guided and held. A grooved guide 11 is provided.

Further, a male type package connector 4 for detachably engaging the package 3 with one board connector 6 is attached to the end edge of one of the option packages 3 forming a set along the extension line thereof. On the other hand, a board connector is provided on the edge of the other optional package 8 forming a pair.
A male type package connector 9 which is detachably engaged with 10 is extended by the attachment pitch P between the board connectors 6 and 10 forming a set in the lateral direction, and is attached parallel to the package 8.

In the embodiment, when mounting one of the optional packages 3 on the backboard 5, the package 3 is inserted into the guide 11 and pushed into the cage 2 as shown in the figure, and the connector 4 at the tip of the package is inserted. The package 3 is engaged with the connector 6 of the backboard 5, and the package 3 is a connector.
It is electrically connected to the backboard 5 via 4, 6.

When replacing one of the option packages 3 with the option package 8 having the connector 9 having the increased number of terminals, one of the option packages 3 is pulled out from the back boat 5 and, instead, the option package 3 is inserted into the guide 11. , This is pushed into the cage 2 so that the connectors 9 and 10 are engaged with each other. In this case, the one board connector 10 forming the set is juxtaposed adjacent to the other board connector 6, and the connector 10 is mounted between the connectors 6 and 10 laterally with respect to the edge of the option package 8. The option package 8 is a guide because it is projected by the pitch P and is arranged in parallel with the package 8.
While being held at 11, the connector 10
Will be detachably engaged with and will be electrically connected to the backboard 5.

Therefore, according to the present invention, two types of connectors 6 and 10 are alternately arranged on the backboard 5 at the same intervals, and the grooves are provided so that the packages can be mounted according to the connector arrangement in the odd rows from the lower stage. A guide 11 is provided, and a package that can be connected to an odd-numbered row connector can be mounted along this guide 11. Furthermore, the package can be removed, and a connector with a height that can be fitted to the other connector in an even-numbered row can be mounted. Slotted guides located in odd rows with different packages having
By using 11 to mount, it is possible to select and mount one of two different types of packages on the same guide as needed.

[Effect of device]

As described above, according to the present invention, two cages can be installed in the same cage.
This has the effect that different types of packages can be mixed and mounted at equal intervals.
