DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mounting structure suitable for use in mounting a connector mounted on a circuit board of, for example, a video tape recorder (hereinafter, referred to as "VTR") to a rear panel. It is.

[0002]

2. Description of the Related Art Generally, for example, an electronic device such as a VTR has a built-in circuit board on which a large number of electronic components are mounted and which is open in both front and rear directions. A front panel having a number of operation switches mounted thereon, a rear panel provided behind the front panel and mounted to close the rear opening in the housing, and mounted on the rear panel and mounted on the circuit board; And a connector for connecting a cable.

Conventionally, as shown in FIG. 4, a connector mounting structure in this kind of electronic equipment has been adopted. This will be described with reference to FIG.
Reference numeral 1 designates a connector insertion port 2 which is attached to a rear portion of a device housing (not shown) and which opens in the front-rear direction, and a tap screw 3 which opens in the same direction as the opening direction of the connector insertion port 2. The panel 4 is provided in front of the panel 1 and is a printed circuit board which is housed in the equipment housing (not shown) and mounts a large number of electronic components (not shown). The connector insertion port 2 is mounted and fixed to the panel 1 by mounting screws 6.
A connector piece 7 partially faces the base piece 8 and the cable connector 9 which are interposed between the device connector 5 and the peripheral edge of the opening of the connector insertion port 2 and have a through hole 8a through which the mounting screw 6 is inserted. This is a lock fitting having a U-shaped cross section including a locking piece 10 to be locked. The base piece 8 of the lock 7 has an opening 11 through which a part of the device connector 5 is inserted.

In such a connector mounting structure,
Attachment of the device connector 5 to the panel 1 is performed by attaching the lock fitting 7 to the device connector 5 and then attaching the lock fitting 7 to the panel 1.
And is fixed by mounting screws 6.

[0005]

By the way, in the conventional connector mounting structure, the printed circuit board 4 is attached to the panel 1.
Since the device connector 5 is mounted from the side opposite to the storage position side, the device connector 5 cannot be mounted on the printed circuit board 4 and then mounted on the panel 1 at the time of mounting the connector. That is, the opening dimension of the connector insertion port 2 is not set to an external dimension sufficient to insert the printed circuit board 4 from the outside of the device housing (rear of the panel) into the device housing (front of the panel). When the connector 5 is mounted, it is necessary to mount the device connector 5 on the panel 1 and then mount the connector 5 on the printed circuit board 4. As a result, the device connector 5 and other electronic components (not shown) cannot be mounted on the printed circuit board 4 in the same process, for example, by soldering or the like, and there is a problem that the assembly of the electronic device becomes complicated. Further, attaching the device connector 5 to the panel 1 via the lock fitting 7 causes a problem that the fastening force of the mounting screw 6 directly acts on the device connector 5 and the device connector 5 is easily damaged when the connector is attached. There was also.

The present invention has been made in view of such circumstances, and provides a connector mounting structure that can easily assemble an electronic device and can prevent damage to the connector when the connector is mounted. Is what you do.
