Abstract

PURPOSE:To enable a continuity test individually for a plurality of switches as well as storage in a small space by integrally covering stationary armatures and movable armatures arranged in a resin sheet with an insulating member so as to independently form the switches on the sheet. CONSTITUTION:A resin sheet 31 is provided with notches 33, 34 so as to be coated with a copper foil, followed by an etching process. Stationary contacts 37, 38 and connecting terminals 39, 40 are formed so that metal plating 41 is applied thereto. An insulating film 42 with a penetrating hole 45 formed thereon as a spacer is stuck onto the contacts 37, 38 and the terminals 39, 40. A movable armature 46 is housed inside the penetrating hole 45, and an insulating film 51 having elasticity is stuck onto the film 42. Consequently, a switch device 52 is formed on the sheet 31. Therefore, a continuity test can be effected individually with respect to the switch devices manufactured in connection, and further, storage in a small space can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to, for example, a micro-sized switch device and a method for manufacturing the same.

(Prior Art) This type of micro-switch device is manufactured continuously using metallic hoop material.

FIG. 6 shows a conventional ultra-small switch device. This switch device 10 first includes a metallic hoop material 1
1 is punched out to form fixed contacts 12, 13 and connecting terminals 14 to 17.

Next, these fixed contacts 12, 13 and connection terminals 14 to
After molding a switch case 18 to 17, a movable contact piece 19 is installed inside this switch case 18.
Finally, an operator (not shown) and a frame for driving the movable contact piece 19 are attached to the switch case 18.

The switch device 10 manufactured as described above is stored attached to the metal hoop material 11 after manufacturing, and is separated from the hoop material 1 when the switch device is arranged on a circuit board. .

By the way, since the hoop material 11 is made of metal, after the switch device 10 is manufactured, it is not possible to individually conduct a continuity test on each switch device while it is attached to the hoop material 11.

Further, since the hoop material 11 is made of metal and has the required strength, even when it is stored by winding it into a roll, the diameter of the roll becomes large and a large storage space is required. .

Furthermore, when disposing the switch device 10 on a circuit board,
It is necessary to separate the switch device] 0 from the hoop material 1, but since the hoop material 11 is made of metal, the switch device 1
In order to separate 1, a large press machine was required.

(Problems to be Solved by the Invention) This invention is capable of individually conducting a continuity test on switch devices manufactured by connecting them together, and requires a large storage space and requires a large-sized device to disconnect the switch devices. This solves the problem of requiring a press machine,
The purpose of this is to make it possible to individually conduct continuity tests on switch devices manufactured in conjunction with each other, and to develop switch devices and devices that do not require large storage spaces or large presses. This paper attempts to provide a manufacturing method for the same.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention provides a resin sheet, a fixed contact piece disposed on the sheet, and a fixed contact piece that comes into contact with the fixed contact piece. A switch device is configured by providing a movable contact piece and an insulating member attached to the seat and covering the fixed contact piece and the movable contact piece.

Further, in order to solve the problem described in item 1, the present invention includes a step of forming a metal film on a resin sheet, a step of forming a fixed contact piece on the metal film, and a step of making contact with the formed fixed contact piece. The switch device is manufactured by a step of disposing a movable contact piece, and a step of forming an insulating film covering the fixed contact piece and the movable contact piece on the resin sheet.

(Function) That is, in the present invention, a fixed contact piece is formed on a resin sheet, a movable contact piece that contacts the fixed contact piece is arranged, and these are integrally covered with an insulating member to form a switch device. By doing this, multiple switch devices can be manufactured independently on a resin sheet, so continuity tests can be performed on each switch in its manufactured state. Because there are
When it is made into a roll, the diameter can be reduced and it can be stored in a narrow space.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIG. 1(a), a film-like resin sheet 31 is provided with a sprocket 32 along the longitudinal direction, and a resin sheet 32 is inserted through this sprocket 32.
1 is adapted to be moved in the longitudinal direction by a drive means (not shown).

First, this resin sheet 31 has a notch 33.3.
4 is formed. Thereafter, adhesive 35 is applied to the surface of the resin sheet 31, as shown in FIG. 3(b), and copper foil 36 is adhered to this portion, as shown in FIG. 3(c). This copper foil 36 has a fixed contact piece 37 as shown in FIG.
38, and connection terminals 39.40 connected to these fixed contact pieces 37.38 are printed.

After this, as shown in the same figure (e), the fixed contact pieces 37, 38,
And the copper foil 36 other than the connection terminals 39 and 40 is removed by etching. At this time, the notch portions 33 and 34
is masked. The fixed contact pieces 37, 38 and the connecting terminals 39, 40 left in this way are shown in the same figure (f).
As shown in the figure, plating 41 is applied to the surface. After that, as shown in the same figure (g), the insulating film 4 as a spacer
2 is glued. As shown in FIG. 2, this insulating film 42 is coated with adhesive 43, 44 on both sides, and is further provided with, for example, triangular through holes 45 in the portions corresponding to the fixed contact pieces 37, 38. It is being This through hole 45
A movable contact piece 46 is accommodated therein, as shown in FIG. 4(h).

FIG. 3 shows the movable contact piece 46.

The movable contact piece 46 has a triangular shape substantially similar to the through hole 45, and is shaped so that each vertex is bent and has elasticity. This diagonal apex 47 is located at the fixed contact piece 3.
7, and the apexes 48 and 49 are brought into contact with the resin sheet 3]. Furthermore, a projection 50 that can come into contact with the fixed contact piece 38 is provided at the center of the movable contact piece 46 .

In the state in which the movable contact piece 46 is accommodated in the through hole 45 as shown in Figure 2, the resilient insulating film 5 is adhered to the insulating film 42, as shown in FIG. 1(1).

As described above, the switch devices 52 are formed on the resin sheet 31, and by repeating the same steps, a plurality of switch devices 52 are formed on the resin sheet 31.

In the switch device 52 thus formed, the resin sheet 31 is wound into a roll shape, for example, and stored in this state.

In addition, when the switch device 52 is disposed on a circuit board or the like, the three connection terminals 40 are cut at the notches 33 and 34 of the resin sheet 31, and the switch device is assembled as a single device as shown in FIG. It is said that

FIG. 5 shows the switch device 52. As shown in FIG.

In this switch device 52, when the insulating film 51 is pressed, the movable contact piece 46 curves and the protrusion 50 comes into contact with the fixed contact piece 38. Therefore, the fixed contact pieces 38 and 37 are electrically connected.

According to the above embodiment, the switch device 52 is formed on the resin sheet 31. Therefore, the resin sheet 31
Even when a plurality of switch devices 52 are manufactured above, since the switch devices are electrically insulated, the continuity test can be performed on each switch device 52 individually.

In addition, since the resin sheet 31 has more flexibility than a metal hoop, the diameter can be made smaller than that of a metal hoop when it is wound into a roll, so it can be used in narrow spaces. It is something that can be saved.

Furthermore, since the connection terminals 39 and 40 are made of copper foil, they can be easily separated from the resin sheet 31.

Further, fixed contact pieces 37 and 38 are printed on the resin sheet 31, and movable contact pieces 46 that contact these fixed contact pieces 37 and 38 are accommodated in the through holes 45 of the insulating film 42, and these are attached to the insulating film 51. Since the switch device is integrally covered with the switch device, it is possible to form an ultra-small and ultra-thin switch device.

[Effects of the Invention] As described in detail above, according to the present invention, a fixed contact piece is formed on a resin sheet, a movable contact piece that contacts the fixed contact piece is arranged, and these are connected to the insulating part. By integrally covering the resin sheets, an ultra-small and ultra-thin switch device can be formed, and moreover, multiple switch devices can be manufactured independently on each resin sheet. Continuity tests can be performed on each switch in its manufactured state, and since a resin sheet is used, the diameter can be reduced when rolled, making it easy to store in small spaces. A possible switch device and a manufacturing method thereof can be provided.
