Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a barrier structure of a primary live power section of an audiovisual apparatus such as a radio-cassette player, a mini computer, and a video.

[0002]

[Prior Art]

 In recent years, the primary live part barrier device has been equipped with a barrier at the rear of the jack hole as a safety measure to prevent direct contact with the primary live part due to the insertion of foreign matter such as a driver or pin through the jack hole of the device. It is realized by arranging plates.

An example of the above-described conventional primary live part barrier structure will be described below with reference to the drawings.

FIG. 5 is a partial cross-sectional side view and front view of a conventional primary live part barrier device. In FIG. 5, generally, this type of primary live part barrier structure comprises an RCA pin jack 4, a barrier plate 10, a mother board 3, a cabinet 6 and screws 11. The barrier plate 10 is arranged at the rear of the jack hole 4b of the jack connection portion 4a of the RCA pin jack 4 and is inserted into the mother board 3 and fixed by soldering together with the RCA pin jack 4, and the end thereof is connected to the RCA pin jack 4 and the cabinet. It is sandwiched by 6 and fixed by screws 11.

[0005]

[Problems to be solved by the device]

 However, in the conventional primary live part barrier device as described above, it is necessary to mount the barrier plate 10 as a separate component on the mother board 3, so that the cost is high and the mounting work is troublesome. Had a point.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide an inexpensive primary live part barrier device which has a good assembling workability.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, a barrier device for a primary live part of the present invention is a power supply board having a primary live part, a part of the power supply board is divided by perforations, and is connected by jumper wires. A divided board, a fitting hole formed in the divided board, and a fitting convex part that fits in the fitting hole formed in the divided part of the power supply board. The fitting holes of the divided board are fitted to the divided board and the divided board is arranged behind the pin jack.

[0008]

[Action]

 With the above-described structure, the present invention eliminates the conventional barrier plate as a separate component, uses a part of the power supply board, and protects the primary live part at low cost simply by dividing and fitting. can do.

[0009]

【Example】

 Hereinafter, an embodiment of a barrier device for a primary live part of the present invention will be described in detail with reference to FIGS.

FIG. 1 is a partial cross-sectional side view of a primary live part barrier device according to a first embodiment of the present invention, FIG. 2 is a front view with the cabinet of FIG. 1 removed, and FIG. 3 shows a pin jack from FIG. The removed front view and FIG. 4 are perspective views of the main barrier structure.

1, FIG. 2, FIG. 3, and FIG. 4, after both ends are joined by the jumper wires 9 soldered to the power supply board 1 and the barrier board 2, the power supply is divided using perforations. The barrier board 2 formed integrally with the board 1 is perpendicular to the power board 1 due to the fitting protrusion 1a formed by dividing the barrier board 2 at the end of the power board 1 and the fitting hole 2a of the barrier board 2. Is fitted to. At this time, the barrier substrate 2 is provided with a guide groove 2b so that the jumper wire 9 is guided and fitted in a fixed position. At this time, the fitting hole 2a of the barrier board 2 is set so that the clearance becomes 1 mm or less after the fitting convex portion 1a of the power supply board 1 is inserted. In addition, components used for the primary live part such as the inlet 5, the fuse 8 and the fuse holder 8a are arranged on the power board 1, and the connector 7 is provided on the mother board 3 at the rear of the RCA pin jack 4 on the mother board 3. It is connector-coupled on 3. At this time, the barrier board 2 is sandwiched between the RCA pin jack 4 and the power supply board 1, and is configured so as not to come off or rotate. A cabinet 6 is arranged in front of the RCA pin jack 4.

As described above, according to this embodiment, the pin (foreign matter) entering through the jack hole 4b of the jack connection portion 4a of the RCA pin jack 4 is stopped by the barrier substrate 2 and comes into contact with the primary live part. In addition, since the barrier board is sandwiched between the power supply board 1 and the RCA pin jack even when it is strongly pressed, it does not come off or rotate.

[0013]

[Effect of the device]

 As described above, the present invention does not require a barrier plate which is a separate component because the barrier substrate is formed by splitting and fitting the barrier substrate configured on the same substrate as the power substrate coupled with the jumper wire. Therefore, it is possible to provide the primary live part barrier device which is easy to assemble and is inexpensive.
