2. Description of the Related Art When a unit board having various electronic components mounted therein is incorporated in a communication device, an OA device or other electronic devices, for example, when the unit plate is inserted into the device, the unit plate is provided on a chassis plate surface arranged inside the device. In many cases, the connector provided on the end edge of the unit plate is electrically and mechanically connected to the receiving connector. For example, in FIG.
(a) and (b) are examples showing such a conventional connector structure. In this example, in the communication device 1, the high frequency component 2 is used.
When assembling the flat transmission unit plate 3 mounted with the device 1 into the device 1, the unit plate is arranged from the direction orthogonal to the chassis plate surface with respect to the flat chassis plate 5 arranged in the opening 4 of the device housing. By inserting 3, the connector 7 provided on the edge of the unit plate is connected to the connector 6 of the receiver provided on the surface of the chassis plate. When inserting the unit plate 3, the unit plate 3 is inserted along the guide plate 8 provided on the inner wall of the opening, and the guide pin 10 provided at an appropriate position of the unit plate 3 is provided with a hole 5a provided at a corresponding position of the chassis plate 5. Positioning is done by plugging in and the connection of both connectors is realized.
Also, as shown in Fig. 5 (b), the connector 7 on the unit board side
Are fixed to the unit plate 3 by screws through L-shaped brackets 11.

However, such a connector structure has the following problems. First, when connecting the connector 7 of the unit plate 3 to the connector 6 on the chassis plate side,
Due to the large weight of the unit plate, a large reaction force acts in the A direction as shown in FIGS. 6 (a) and 6 (b), and as a result, the L-shaped bracket 11 bends and the L-shaped bracket made of a thin plate. Cracks and breaks occur at the portion B of 11 and cause deterioration of the durability of the unit plate 3. Further, although the guide pin 10 is provided on the unit plate side for connecting both connectors, since the guide pin 10 is a protrusion on the unit plate side, an operator may be injured by this pin. Accidents tend to occur, which poses a problem in terms of safety, and in many cases the guide pins may hit other parts and break when the unit board is handled. Furthermore, since the hole 5a for inserting the guide pin 10 is formed on the chassis side, dust easily enters the inside of the casing below the chassis through this hole 5a, and if dust adheres to an electric circuit or the like. ,
Accidents such as short circuits are likely to occur. Also, this hole is
When the chassis itself is exposed to the outside, it causes the appearance to deteriorate.
