DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug-in connection structure for electrically connecting a connector of a first housing constituting a main body of an electronic apparatus and a connector of a second housing such as an extension device. In particular, the present invention relates to a plug-in connection structure suitable for use when attaching and connecting an extension device to a basic device in communication equipment of a base station or the like.

[0002]

2. Description of the Related Art Conventionally, in base station communication equipment, etc.,
In some cases, it is necessary to attach an additional device to the basic device and connect it. As a connection structure between the basic device and the extension device used in this case, there is a so-called plug-in connection structure.

FIG. 12 is an exploded perspective view showing a conventional plug-in connection structure, and FIG. 13 is a perspective view showing a housing constituting a main body of the plug-in connection structure. In FIG. The (first) housing 2 to be constituted is the housing 1
A box (second housing) of an additional device which is electrically connected as an option, 3 is a connector provided at the center of the connection surface 2a of the box 2, and 4 is provided at the center of the connection surface 1a of the housing 1. A connector, which is electrically connected to the connector 3, and a plate 5 for fixing the housing 1 and the box 2,
Reference numeral 6 denotes a screw for fixing the plate 5, and reference numeral 7 denotes a screw hole.

When a box 2 which is an additional device is plug-in connected to a housing 1 constituting the main body, a connector 3 of the box 2 is connected to a connector 4 of the housing 1 and then the housing 1
The two side surfaces 1b and 2b of the box 2 are fixed to each other by the plate 5 and the screws 6.

[0005]

The first problem is that when a connection work is performed in a place where it is difficult to work, such as a high place or a narrow place, the connector 4 is located on the rear surface of the housing 1 and is visually observed. Since the positions of the connectors 3 and 4 are difficult to confirm and the connection between the connectors 3 and 4 may not be performed well, the connectors 3 and 4 cannot be easily connected, or an unnecessary force is applied to the connectors 3 and 4 and the connectors 3 and 4 are damaged. And the like.

The second problem is that since both sides 1b and 2b of the housing 1 and the box 2 are fixed to each other by the plate 5 and the screw 6, another member such as the plate 5 and the screw 6 and a tool are used. That is, it is necessary. Also, housing 1
When fixing both sides 1b and 2b of the box 2 with the plate 5 and the screw 6, the work must be performed while holding the plate 5 and the screw 6 by hand, which is difficult. Further, in a narrow place, a space required for using a screwdriver cannot be obtained, and there is a case that fixing by the screw 6 cannot be performed.

[0007] The present invention has been made in view of the above circumstances, and can be easily connected even when performing a connection work in a difficult place such as a high place or a narrow place, the connection member It is an object of the present invention to provide a plug-in connection structure which does not require any tools or tools, and is excellent in operability and maintainability.
