DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a microphone terminal or the like.

[0002]

2. Description of the Related Art As shown in FIG. 5, after a microphone terminal 1 is soldered to a substrate 2, the microphone terminal 1 is inserted into a through hole (not shown) of a mounting bracket 3 and fixed by a stopper 4. The mounting bracket 3 is screwed to the boss 6 of the front panel 5 with a screw 7. Reference numeral 8 denotes a connector for electrical connection, which is connected to a main board (not shown) of the main body via a lead wire 8a, and then the front panel 5 is attached to a main body chassis (not shown). 5a is a through hole.

[0003]

When the microphone terminal is attached to the front panel as described above, especially when a large microphone terminal is used, a considerable space must be secured on the front panel. In order to obtain a sense of stability, the structure of the mounting bracket becomes complicated. Further, for electrical connection, preparation work is required over both the substrate on the main body chassis side and the front panel side, resulting in poor work efficiency.

[0004]

According to the present invention, there is provided a front panel having a grounding fitting having an elastic tongue attached thereto,
A chassis having an opening, a positioning protrusion and an attachment boss in the vicinity of the opening, a microphone terminal having a plurality of slits attached to the substrate, a first through hole and a projection through which the microphone terminal is inserted, and The second and third provided opposite the boss
It has a through hole, and further includes a mounting bracket having a tongue piece locked in the opening, and a stopper fitting engaged with the slit,
When the front panel is assembled after the microphone terminal is fixed to the mounting bracket with a fastener and attached to the chassis, the tongue piece is brought into contact with the mounting bracket.

[0005]

With the above arrangement, the microphone terminal attached to the mounting bracket engages the projection of the chassis and the boss with the first and second through holes of the mounting bracket, and engages the tongue piece with the opening. When stopped, it is temporarily held on the chassis. Further fixing with screws secures the microphone terminal. When the front panel is attached, the tongue contacts the mounting bracket, and the microphone terminal is grounded.

In the figure, the same parts as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

Reference numeral 11 denotes an opening 11a and a positioning projection 11
A chassis 12 in which b, 11b and attachment bosses 11c, 11c are formed, 12 is a first through hole 1 through which the microphone terminal 1 is inserted
2a, 12a, second through-holes 12b, 12b and third through-hole 12 formed facing projection 11b and boss 11c.
c, 12c and a mounting bracket integrally formed with a tongue piece 12d locked in the opening 11a, and 13 is a projection 13a and a projection 13
b is formed on the front panel, 14 is an elastic tongue 14a
And a through-hole 14b and a bent piece 14c. Note that the microphone terminal 1 is provided with a slit 1a with which the stopper 4 is engaged. The stopper 4 has a U-shaped notch 4a as shown in FIG. 2, but may have an inverted U-shaped notch 4b as shown by a dotted line.

In the procedure for assembling the above components, first, the microphone terminal 1 is soldered to the substrate 2. Next, the microphone terminal 1 is inserted through the through hole 12a of the mounting bracket 12, and the stopper 4 is engaged with the slit 1a (see FIG. 1). Next, when the tongue piece 12d is engaged with the back surface of the opening 11a while the through hole 12b of the mounting bracket 12 is inserted into the projection 11b of the chassis 11 so as to face the protrusion, the through holes 12c face the bosses 11c. In this state, the mounting fixture 12 with the microphone terminal is temporarily fixed in the left, right, up and down directions, and is temporarily held by the chassis 11. Finally, if fixed with screws 15, the microphone terminal 1 will be
Fixed securely.

FIG. 3 shows a grounding bracket 1 on a front panel 13.
4 shows a state in which 4 is attached. The boss 13a of the front panel 13 is inserted and fused into the through hole 14b of the grounding metal fitting 14, and the bent piece 14c is fitted to the protruding piece 13b. The elastic tongue piece 14a contacts the edge of the mounting bracket 12 (see FIG. 4). Therefore, the bent piece 14c of the grounding metal 14
If the microphone terminal 1 is screwed to the metal bottom plate 16 or the like, the microphone terminal 1 is grounded, and countermeasures against static electricity are taken.

In the above-described configuration, if the fastener 4 is removed with the front panel 13 removed, the substrate 2 with the microphone terminal can be removed, so that workability during service repair and inspection is improved.

[0011]

According to the above configuration, the microphone terminal mounting bracket can be temporarily held on the chassis before screwing, and can be easily attached and detached, so that the work efficiency is high. Since the microphone terminal mounting bracket is attached to the chassis side, the microphone terminal substrate can be detached alone with the front panel removed, thereby improving serviceability. Since the mounting bracket can be grounded by attaching the front panel, it is effective as a measure against static electricity.
