Description

[Detailed description of the invention] [Summary] A plurality of rotary switches are formed into a U-shape so that they can be attached to the crown, and a hole for operating each rotary switch is provided on the main surface of the shape. A display bracket that is attached to the top of each mounted rotary switch by printing an operation display and providing a notch on the end face of the side wall to prevent contact between the mounting leg that is attached to the printed board and the wiring pattern.

[Industrial application field]

The present invention relates to a display fitting for a rotary switch.

In particular, the printed circuit board for setting the telephone office number used for the meeting line of optical communication transmission equipment has many elements and 3
Each rotary switch is used to set a 3-digit telephone office number as necessary. For this reason, an operation display is provided on the main surface of the printed board to ensure the setting of the telephone office number, but since the display space becomes large, a three-dimensional rotary switch display metal fitting is required.

[Conventional technology]

As shown in FIG. 2, the conventional method of displaying rotary switches is to place a mark on the main surface of a printed circuit board 2 for setting a telephone office number used for a meeting line, around a portion 4 where the rotary switch 1 is mounted. The operation display 3 is formed by etching when forming the substrate or by stamping after forming the substrate.

As shown in FIG. 3a, a position display different from the display on the main surface of the substrate 2, for example 0
～9 and A～F position display 1-1 are provided,
It is a top setting type having an operation groove 1-2 for switching between 16 positions, and is equipped with a complementary cord rotary switch 1 formed with a connection terminal 1-2 shown in the bottom view (b).

[Problem that the invention attempts to solve]

The problems with the conventional rotary switch display method described above are that, because a display for a purpose different from the display content of the rotary switch to be mounted is displayed on the main surface of the printed circuit board, it becomes impossible to mount other electronic components in that display area, and there is a risk of erroneous operation of switching the rotary switch.

Therefore, the printed board for setting the telephone office number becomes large, and the shelf on which the printed board is mounted also becomes large, which increases the cost of the device and causes incorrect setting of the telephone office number.

In view of the above-mentioned circumstances, the present invention has three-dimensionalized the operation display section and can mount many electronic components.
The object of the present invention is to provide a display metal fitting that allows a rotary switch to be used for a purpose other than the displayed content.

[Means for solving problems]

The above problem is caused by the main surface 13 as shown in Figure 1a.
Three operation holes 13-1a are provided at the bottom of the board 2, and the position of the rotary switch 1 is printed around the holes 13-1a, and a display 13-1b for setting the telephone number is printed on the top of the board 2. On the side wall 13-2 of the metal fitting formed into a U-shape when viewed from below so that the mounted rotary switch 1 can be attached to the top, there are fastening means, that is, attachment means, for the printed board 2 at both upper and lower edges, respectively, as shown in Figure b. A notch 13-2b is disposed to protrude from the end surface of the leg 13-2a, and a notch 13-2b is provided in the middle of the mounting leg 13-2a.
This problem is solved by the rotary switch display metal fitting of the present invention.

[Effect]

That is, in the present invention, the side wall 13-2 is arranged such that the operating hole 13-1a faces the operating groove 1-2 of the rotary switch 1 mounted on the printed board 2.
Insert the mounting legs 13-2a provided on the end faces of the rotary switch 1 into through-holes (not shown) of the printed board 2, solder the mounting legs 13-2a and the through-holes, and attach the display bracket to the top of the rotary switch 1. By capping the position display on the top surface of the rotary switch 1 without contacting the wiring pattern formed on the main surface of the printed board 2, the position display is hidden on the main surface 13-1 of the display bracket, and the telephone office number Since there is a space between the main surface 13-1 on which the setting display 13-1b is printed and the main surface of the printed board 2, at least the height of the rotary switch 1, other electronic components can be mounted close to the rotary switch 1. becomes possible.

〔Example〕

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 shows a perspective view of a rotary switch display fitting according to this embodiment, and in the figure, the same members as in FIG. 2 are given the same symbols.

The rotary switch display fitting is made of a rectangular thin metal plate formed into a U-shape when viewed from the front with a size and height that can be attached to the rotary switch 1, as shown in c in Fig. 1. Provide a wall 13-2,
A hole 13- for inserting a driver to change the position of the rotary switch 1 on its main surface 13-1.
Three pieces 1a are arranged at the bottom in front view.

Next, as shown in Figure b, narrow mounting legs 13-2a that can be inserted into through holes (not shown) of the printed board 2 are attached to the upper and lower edges of both side walls 13-2.
is arranged so as to protrude from the end surface, and its mounting leg 13-
A cutout 13-2b is provided on the intermediate end surface of the printed board 2a to prevent contact with a pattern (not shown) formed on the main surface of the printed board 2, and if necessary, the entire surface is plated with nickel, as shown in Figure a. Main surface 13
-1 has a switching position for setting a telephone office number different from rotary switch 1 and an operation display 13-
1b is being printed. Then, the rotary switch 1 is mounted by inserting the connecting terminal 1-3 shown in FIG.
Insert each of the mounting legs 13-2a shown in Figure b into the through holes (not shown) of the printed board 2 so that the hole 13-1a for inserting the driver faces 2, and print by immersing them in a solder bath. The rotary switch 1 and the rotary switch display fitting of the present invention are mounted on the board 2.

As a result, the main surface 1 of the rotary switch indicator metal fitting
A space is created between 3-1 and the main surface of the printed circuit board 2, making it possible to mount other electronic components in that space, preventing the size of the printed circuit board 2 from increasing and concealing the position indicators arranged on the upper surface of the rotary switch 1.

[Effect of idea]

As explained above, the present invention has the advantage that it is possible to mount more electronic components on a printed board than before with an extremely simple configuration, and that it can be used for a purpose other than the display of a rotary switch, reducing the number of types. It is expected to have significant economic effects and is extremely useful industrially.
