Description

[Detailed Description of the Invention] The present invention relates to an electrical component mounting device that facilitates service inspection.

In recent years, many electronic devices have been becoming more and more compact depending on their use, and when it is not possible to make parts more compact in order to achieve that purpose, it is necessary to change their arrangement or change the original mounting state of the parts. Forced to install in different conditions.

However, judging from the standpoint of service inspection, this tendency is difficult to describe as complicated or difficult.

For example, television signal receivers for VTRs are also becoming thinner, with little relation to the miniaturization of tuners.

Therefore, the vertically long tuner must be mounted horizontally, and the mounting cover cannot be removed during service inspection.

Therefore, the present invention aims to provide an electrical component mounting device that allows the tuner installed on the side to be erected when in operation, in order to enable service inspection of the tuner simply by removing the top plate of the television signal receiver. .

The present invention will be described in detail below with reference to an illustrative embodiment.In this embodiment, the present invention is applied to a thin VTR television signal receiver in which a vertically elongated VHF tuner is installed horizontally in parallel with a UHF tuner.

FIG. 1 shows an exploded perspective view of essential parts of this embodiment, and the national policy 1 is a VHF tuner.

The VHF tuner consists of a substantially U-shaped mounting cover 1C and a tuner base 1b, and four screw holes 1a, 1a, . . . are bored in the bottom surface of the tuner base 1b'.

Also, drawing number 2 is a mounting plate for the VHF tuner 1, and there are through holes 2a at the positions that contact the screw holes 1a, la...
, 2a, . . . , L-shaped tongue pieces 2b, 2b extending downward from the tuner mounting portion of the mounting plate 2 are provided with screw holes 2c, 2c, respectively, for mounting mounting position fixing screws.

Furthermore, figure number 3 is a support member for fixing the mounting plate 2 to the chassis.

The support member 3 includes the L-shaped tongue piece 2b of the mounting plate 2.

A sliding portion and a curved tongue piece 2b that slides and guides the sliding portion 2b.

a first guide 3 comprising a rotating part that allows the mounting plate 2 to rotate around the support member when the mounting plate 2b is guided to the rear end;
a, 3a, a regulating path for regulating and guiding the mounting position fixing screws 4, 4 screwed onto the tongue pieces 2c, 2c, and a regulating path for regulating and guiding the mounting position fixing screws 4, 4, which are screwed onto the tongue pieces 2c, 2c; Second guides 3b, 3b each having a large diameter portion are disposed from which screws No. 4 are removed as the mounting plate 20 is rotated.

The assembly work of this embodiment will be described below.

First, the mounting plate 2 is screwed and fixed to the bottom of the VHF tuner 1.

Next is the L-shaped tongue piece 2b of the mounting plate 2. 2b is fitted into the rotating portion of the first guides 3a, 3a of the support member 3 fixed to the chassis.

Further, in the fitted state, the mounting position fixing screws 4, 4 are screwed into the screw holes 2cy2c as described in (h) through the large diameter portions of the second guides 3b, 3b in a loosened state.

Finally, the VHF tuner 1 fixed to the mounting plate 2 is slid forward and the shaft portion 1 of the VHF tuner 1 is moved forward.
Insert a into the hole in the cabinet front panel 7,
The installation is completed by firmly tightening the installation position fixing screws 4, 4.

The operation during service inspection will be described below.

First, remove the top plate 6 of the cabinet and loosen the mounting position fixing screws 4, 4.

Next, in order to remove the shaft portion 1a of the VHF tuner 1 that protrudes from the hole in the cabinet front panel 7 from the hole, the VHF
Slide the F tuner itself towards the back.

If the tuner 1 is rotated while sliding further inward, the tuner 1 rotates 90' around the rotating portions of the first guides 3a and 3a and is locked.

In this state, the bent portions of the above-mentioned cross-shaped tongues 2b, 2b serve to prevent removal.

Finally, service inspection becomes possible by removing the mounting cover 10 of the VHF tuner located above in the rotationally locked state (as shown in FIG. 3).

However, in this embodiment, the UHF tuners 5, which are installed in parallel near the cabinet side plate 8, are horizontally long, and the V
Since it is smaller than the HF tuner 1, the longitudinal direction of the UHF tuner is vertically opposite to that of the VHF tuner 1 to gain installation space.
It faces the mounting cover 10 of the HF tuner.

Therefore, the UHF tuner 5 can also be inspected for screws when the VHF tuner 1 is rotated.

According to the present invention, not only the service inspection work becomes easier, but also the device body can be made thinner.
