Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] A state in which a notch is provided in a side edge of a component mounting board disposed in a housing, a wire is held in the notch, and the board is pressed toward a wall of the housing. A wire rod fixing structure in which the wire rod is fixed and held between the substrate and the wall body easily and securely with a simple structure.

[Industrial application field]

The present invention relates to a fixing structure for a wire such as a lead wire connected to a printed board or the like in various electronic device housings.

FIG. 4 shows the appearance of a telephone terminal as an example of an electronic device to which the present invention is applied. The telephone 5 has various electronic circuits inside,
It is composed of a housing 1 containing a speaker and the like. The upper surface of the housing 1 is provided with a receiver installation section 2 and an operation section 3 including various push buttons.
And a liquid crystal display unit 4 having a display screen 6. The liquid crystal display unit 4 accommodates a brightness adjusting volume of the liquid crystal display screen, and the brightness is adjusted by sliding the knob 7 as shown by an arrow A. Such a liquid crystal display unit 4 can be attached to and detached from the telephone 5 as a display unit, and this part can be covered with a blind blank for makeup without the liquid crystal display unit 4. Therefore, the circuit of the liquid crystal display unit 4 is connected to the internal circuit of the housing 1 when the telephone is assembled. The internal lead wires must be securely fixed in a position where there is no hindrance in order to perform such a circuit assembly work without any hindrance and to smoothly perform the operation of the movable part such as the brightness adjustment operation.

[Conventional technology]

FIG. 5 shows a conventional internal wiring fixing structure of a liquid crystal display unit.
FIG. 5 is a view of the liquid crystal display unit 4 removed from the telephone and viewed from the bottom side. Further, FIG. 7 shows a BB cross section of FIG. A board (printed board) 8 on which a liquid crystal display control circuit is mounted is housed in an outer cap-shaped housing 9 made of a plastic molded body. The board 8 is fixed to the boss 18 (FIG. 7) on the housing 9 side with the screw 10. Reference numeral 17 is a flexible cable for connecting the circuit of the substrate 8 and the control circuit in the telephone. Another substrate 11 having a volume 13 mounted thereon is mounted adjacent to the substrate 8.
The volume 13 is a slide type volume control for adjusting the brightness of the liquid crystal display screen, and a slide member 14 is projected on the upper surface. The end of the operating knob 7 is fitted to the slide member 14, and the knob 13 is operated by sliding the knob 7 as shown by arrow A. The board 11 is fixed to the boss 19 (FIG. 7) on the housing 9 side with the screw 12. There are two lead wires 15 on the substrate 11 on which the volume 13 is mounted.
Are connected. Conventionally, the lead wire 15 has been fixedly held by being inserted into the slit 23 of the holding piece 16 provided on the inner surface of the housing 9 as shown in FIG. 6 (a). Holding piece 1
Instead of 6, as shown in FIG. 6 (b), a plurality of pins 24
There is also a case where the wire rod 15 is projectingly provided on the inner surface of the housing 9 and the wire member 15 is sandwiched between the pins 24 in a zigzag shape and fixed.

[Problems to be solved by the invention]

In the wire fixing structure using the conventional holding piece 16 or the pin 24, the fixing force cannot be adjusted according to the thickness of the lead wire, the number of the lead wires, etc., and the lead wire may fall out, which is a reliable lead wire. Could not be fixed.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a wire rod fixing structure that securely holds a lead wire with a simple structure.

[Means for solving problems]

In order to achieve the above object, in the present invention, a component mounting board disposed in a housing is provided with a long hole through hole for fixing a screw, a notch is provided at a side edge of the board, and a wire rod is provided in the notch. Provided is a wire rod fixing structure in which the wire rod is fixed and held between the substrate and the wall body by screwing the substrate while holding and pressing the substrate against the wall of the housing.

[Action]

A wire is arranged in the notch on the side edge of the substrate and the substrate is pressed against the wall of the housing, and the substrate is fixed to the housing in this state. The wire is fixedly held by being sandwiched between the substrate and the wall.

〔Example〕

FIG. 1 shows a wire fixing structure for a liquid crystal display (unit) of a telephone according to the present invention. FIG. 1 is a view seen from the bottom of the unit as in FIG. FIG. 2 is a sectional view taken along the line CC of FIG. The same components as those in FIG. 5 are designated by the same reference numerals and the description thereof will be omitted. In this embodiment, the substrate 11 on which the volume 13 is mounted is
The lead wire 15 is sandwiched and fixed between the wall body 25 and the wall body 25 constituting the housing 9. As shown in FIG. 3, a notch 20 is formed on the side edge portion of the substrate 11. Wire 15
Is held in the notch 20 and pressed against the wall 25. The through hole for screwing the substrate 11 is formed as a long hole 19 as shown in FIG. This allows the substrate 11 to move with respect to the wall 25,
The clearance between the wall 25 and the wall 25 can be adjusted. The lead wire 15 is held in the notch 20 of the substrate 11, the substrate 11 is pressed against the wall 25 side, and the substrate 11 is fixed to the housing side with the screw 12. A connector (not shown) for connecting to the liquid crystal display control circuit of the substrate 8 is attached to the tip of the lead wire 15. Reference numeral 21 in FIG. 3 is a hole for mounting the volume,
2 is a lead wire connection hole.

[Effect of device]

As described above, in the wire rod fixing structure according to the present invention, a special member for fixing the wire rod is provided by the simple structure in which the wire rod is sandwiched and fixed between the component mounting board and the wall of the housing. The wire rod can be securely fixed without using it, the wire rod does not hinder the assembly work, and the smooth operation of the movable part is achieved. Also, by making the through holes for screw mounting of the board long holes, it is possible to adjust the gap between the board and the wall body, and fix the wire with the optimum pressing force according to the thickness and number of wires. The wire rod can be securely held.
