Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a high frequency circuit device such as an RF modulator which is mounted in a device such as a video tape recorder device with its input / output terminals projecting outward. Regarding mounting structure.

[Problems to be solved by conventional techniques and devices]

2. Description of the Related Art Conventionally, as a high-frequency circuit device mounted in a video tape recorder device with its input / output terminals protruding to the outside, for example, there is an RF modulator 1 as shown in the perspective view of FIG. Is formed integrally with the case 1 by attaching the mounting foot 2 to be mounted on the substrate in the device, and the input / output terminals 4 and 5 are spaced apart and projected at one part of the pair of covers 3 provided on the side surfaces, and further on the same surface. An empty channel changeover switch 6 is provided. Next, the mounting state of the RF modulator 1 on the device 7 such as a video tape recorder will be described. As shown in FIG. 4, the mounting foot 2 is inserted and soldered on the circuit board 8 of the device 7. At this time, the input / output terminals 4 and 5 are provided so as to project from the openings 9a and 9b provided in the rear panel 9 of the device 7 in a loose fit around the terminals. From the opening 9c provided in the
The mounting structure is such that 6a is arranged in a protruding state.

However, since the input / output terminals 4 and 5 project from the openings 9a and 9b of the rear panel 9 in a loosely fitted state in the mounting state of this conventional configuration, the openings 9a and 9b can be accurately mounted at the time of mounting. The problem is that it is not attached so that it protrudes from the center of the switch and it is attached in a state that it is offset to one side in the horizontal direction, and at that time, the operating element 6a of the changeover switch 6 does not exactly match the opening 9c, and in extreme cases the switch cannot be operated. There were dots. Further, when the operator 6a of the changeover switch 6 is frequently operated, the RF modulator 1 is not positioned because the input / output terminals 4 and 5 are loosely fitted, and the operating force of the changeover switch 6 is not adjusted. However, there is a problem that the RF modulator 1 is increased in number and acts on the soldered portion of the mounting foot 2 of the RF modulator 1 to hinder the mounting of the RF modulator 1.

[Means and Actions for Solving Problems]

The present invention was devised to solve the above-mentioned problems, and its means has mounting feet for mounting and fixing to a circuit board of an external device, and mounting and fixing a plurality of input / output terminals on one surface side. A case body, a manually operable operation portion provided on the one surface side, a through hole through which the input / output terminal penetrates, and an operation hole for allowing the operation portion to be operated, A guide hole formed between the input / output terminal and the case cover that covers the one surface side, the guide hole penetrating the case cover and the case body and into which the protrusion provided in the external device is inserted and fitted; The input / output terminal is projected to the outside, and the operating portion is incorporated in the external device in a state in which it can be operated from the outside. is there. In addition, by providing a projection inside the panel surface of the device such as a video tape recorder and fitting the guide hole into the guide hole, the high frequency circuit device can be reliably operated and other external force is applied to the soldered portion. Fixed so that there is no.

〔Example〕

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

FIG. 1 is a perspective view of a high frequency circuit device according to the present invention.
The figure is a cross-sectional view of a main portion showing the attached state. As shown in the figure, the high-frequency circuit device 10 is mounted on the case body 11 with the mounting feet 12
The input / output terminals 13 and 14 are provided so as to project from the case cover 15 from one side surface thereof, and the channel changeover switch 16 is provided on the same side of the case cover 1 with the operator 16a.
It is arranged so as to project from 5, and one guide hole 16 is provided between the input / output terminals 13 and 14 so as to penetrate the case body 11 and the case cover 15. is there.

Next, the mounting state will be described with reference to the cross-sectional view of FIG. 2. The high frequency circuit device 10 is fixed by fixing the mounting feet 12 to the circuit board 18 of the device 17 such as a video tape recorder by soldering. The output terminals 13 and 14 are provided so as to project from the openings 19a and 19b provided in the rear panel 19 of the device 17, respectively, and the changeover switch 16 is also provided so as to project from the opening 19c (shown). At this time, the projection 20 provided inside the rear panel 19 of the device 17 is inserted and fitted into the guide hole 16 of the high-frequency circuit device 10, and the high-frequency circuit device 10 is securely placed in the device 17 by the projection 20 and the guide hole 16. It will be positioned and fixed. The position of the guide hole 16 is not limited to the position between the input / output terminals 13 and 14 shown in the embodiment, but this portion is preferable.

〔effect〕

Therefore, according to the high-frequency circuit device of the present invention having the above-mentioned configuration, when mounting and fixing the high-frequency circuit device, a positioning bid hole is provided, and the guide hole and the projection provided on the rear panel of the setting device are fitted to each other. Since the input and output terminals of the high-frequency circuit device are arranged to project in a loosely fitted state because they are positioned and fixed, the high-frequency circuit device can be positioned substantially at the center of the opening provided in the rear panel, and the appearance can be improved. At the same time, it can be positioned at a predetermined opening position of another operation part, preventing the occurrence of operation failure, and further, the external force due to the lever action caused by the operation of the operation part is exerted on the mounting foot part of the high-frequency circuit device. Therefore, it is possible to obtain an effect that the arrangement and fixation in the setting device can be reliably maintained. Further, since the guide hole is provided between the portions of the case body where the input / output terminals are rigidly formed to apply an external force, the guide hole can sufficiently withstand the external force.
