Description

[Detailed description of the invention] Industrial field of application The invention relates to a coupling device that can be used when coupling an adapter to a computer that processes data using a CPU (central processing unit). be.

Conventional configurations and their problems Computers that use tape recorders, audio interfaces, etc. as adapters have conventionally been placed in a separate location from the computer main body and electrically connected with cords and cables. Therefore, when carrying the main body, it is necessary to separate the adapters individually and carry them, which has the disadvantage of being inconvenient to handle.

Purpose of the invention It is an object of the present invention to eliminate the above-mentioned drawbacks and to provide a coupling device that can be used in cases where an adapter and a main body are mechanically coupled and can be carried.

Structure of the Invention In the present invention, both sides of the object to be connected and the object to be connected are aligned and then pressed against each other, and the object to be connected and the object to be connected are electrically connected by a pair of connectors.
At that time, temporarily remove the threaded rod protruding from the joint.
It is configured so that it can be pulled into the adapter, and then, as the knob is rotated, the threaded rod fits into the threaded hole on the main body.

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

As shown in Fig. 1, a computer main body (unit to be connected) 1 including a CPU has a liquid crystal display 2 for displaying characters, graphics, etc., and a plurality of key switches 3 for input.
are provided on the same plane, and the adapter assembly 4 is placed on the right side. Although not described in detail, the adapter 4 may have a built-in audio interface circuit or a cassette/tape recorder as an external storage device for data, and as long as it can be used as an auxiliary auxiliary device for the main body 1, its contents are particularly limited. It's not something.

A portion of the knob 5 is exposed through the aperture 7 of the adapter case 6, so that it can be easily rotated from the outside. As shown in Figures 2 and 3,
The threaded rod 8 is provided perpendicularly to the wall surface 6A of the adapter case 6.
One end is supported for rotation. The threaded rod 8 is constructed concentrically with the knob 5, and a toothed wheel 9 of the threaded rod 8 meshes with the inner peripheral portion of the knob 5 so as to be able to slide in the axial direction (FIG. 4). The bearing 10 is appropriately supported by the case 6 and rotatably holds the other end of the threaded rod 8. Therefore, when the knob 5 is rotated, the threaded rod 8 is rotated. A compression spring 11 is provided between the toothed wheel 9 and the bearing 10 of the threaded rod 8, and this compression spring 11 presses the threaded rod 8 toward the outside of the case 6. The main body 1 has a data transfer connector 12 for the main body 1 as shown in FIG.
Further, a screw hole 13 is arranged. The adapter 4 is mated with the connector 12 of the main body 1,
Connector 14 for electrical connection is connected to threaded rod 8
It is provided on the same surface as the protruding surface of. Further, as described above, the threaded rod 8 is movable in its axial direction, but is configured such that the amount of movement thereof is greater than the insertion depth of the connectors 12 and 14.

When the main body 1 and the adapter 4 are not connected, they are completely separated as shown in FIG.
At the time of fastening, the connectors 12 and 14 are brought together and at the same time, both are placed in a position where the threaded rod 8 and the threaded hole 13 face each other. At this time, the positional relationship between the main body 1 and the adapter 4 is regulated by the engagement of the convex portion 15 and the concave portion surface 16 (FIG. 5) provided on each.

When the main body 1 and the adapter 14 are aligned and pressed together, the connectors 12 and 14 are first connected. At this time, the threaded rod 8 moves against the spring 11 so as to be drawn into the adapter 4. Next, when the knob 5 is rotated, the threaded rod 8 is pressed by the compression spring 11 and engages with the threaded hole 13, thereby bringing the main body 1 and the adapter 4 into close contact with each other.

When aligning the main body 1 and the adapter 4, the threaded rod 8 temporarily enters the adapter 4 in the direction of compressing the compression spring 11, thereby facilitating the mating of the connectors 12 and 14.

Effects of the Invention As explained above, according to the present invention, it is possible to easily connect the object to be connected such as a computer body, the connected object such as an adapter, the threaded rod and the threaded hole, and the knob and the threaded rod can be connected concentrically. Since the screw rod and the knob can be interlocked in a narrow space, the connecting structure can be easily made compact. Further, by employing screw fastening, the two can be brought into close contact extremely firmly, and application to devices that are susceptible to external loads such as vibrations, especially portable devices, is effective in increasing the reliability of fastening.

Furthermore, in order to make an electrical connection using a connector in preference to a mechanical connection using a screw, when the knob is rotated to turn the screw, the connector does not move relative to the other, and no force is applied to the connector pin. This has the effect that no load is applied.
