Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a thin push switch.

[Conventional technology]

Recently, thin push switches with a laminated structure that do not use a switch case have been considered as push switches.

This thin push switch has a lower fixed contact plate which has terminals on the outer edge and a contact part protruding from the upper surface of the center part, and an opening corresponding to the contact part of the lower fixed contact plate in the center part. Insulating spacer sheets are stacked, and on top of this spacer sheet is a movable contact plate consisting of a flat circular metal spring plate that swells upward and curves into a spherical shape, and a terminal is provided on the outer edge and the movable contact plate is provided in the center. The movable contact plate is in electrical conductive contact with the upper fixed contact plate at its outer peripheral edge. This thin push switch is turned on by pressing the movable contact plate exposed in the opening of the fixed contact plate. When the movable contact plate is pressed, it swells upward and curves into a spherical shape. The movable contact plate is bent downward due to the pressing force and comes into contact with the contact part of the lower fixed contact plate.
The upper fixed contact plate and the lower fixed contact plate are electrically connected via the movable contact plate, and the switch is turned on. Furthermore, when the pressing force on the movable contact plate is released, the movable contact plate is restored to its upwardly swollen state by its spring force and separates from the contact portion of the lower fixed contact plate, turning the switch off.

By the way, since this thin push switch has a laminated structure as described above, manufacturing this thin push switch requires a lower fixed contact plate, an insulating spacer sheet, a movable contact plate, and an upper fixed contact plate. It is necessary to align and fix them with each other.

For this reason, conventionally, an insulating spacer sheet, a movable contact plate, and an upper fixed contact plate were sequentially aligned and stacked on top of the lower fixed contact plate, and then protrusions were provided at several locations on the outer periphery of the upper fixed contact plate. The upper fixed contact plate and the lower fixed contact plate are fixed with the spacer sheet and the movable contact plate sandwiched between them by bending and latching the claws to the lower surface of the lower fixed contact plate, or The movable contact plate is fixed to the fixed contact plate by sandwiching its outer peripheral edge between the opening peripheral edge of the upper fixed contact plate and a tongue protruding from this opening peripheral edge, and is insulated from the lower fixed contact plate. After aligning and stacking the spacer sheet and the upper fixed contact plate to which the movable contact plate is fixed, the claws protruding from the outer periphery of the upper fixed contact plate are attached to the bottom surface of the lower fixed contact plate in the same manner as in the above method. By bending and latching, the switch is assembled by fixing the upper fixed contact plate and the lower fixed contact plate with the spacer sheet sandwiched therebetween. In this case, if the claw part is directly hooked to the lower fixed contact plate, the lower fixed contact plate and the upper fixed contact plate will be short-circuited through the claw part, so in the above manufacturing method, the insulating spacer sheet By forming a protruding piece that overlaps the inside of the claw on the outer peripheral edge of the claw and inserting this protruding piece between the claw and the lower fixed contact plate, the claw and the lower fixed contact plate can be connected to each other. (Utility Model Application Publication No. 57-7118 and Utility Model Application No. 59-2)
(See Publication No. 8924).

[Problem to be solved by the invention]

However, in the conventional manufacturing method for thin push switches described above, the switches are assembled one by one, and in order to assemble the switches, claws protruding from several locations on the outer periphery of the upper fixed contact plate are used. Since the switch must be bent and hooked onto the lower surface of the lower fixed contact plate, there is a problem in that the manufacturing efficiency of the switch is low.

The present invention was made in view of the above two circumstances, and its purpose is to provide a method for manufacturing a thin push switch that can efficiently manufacture a thin push switch having a laminated structure. It is about providing.

It consists of an upper fixed contact tape formed side by side in the length direction, and a flat circular metal spring plate that swells upward and curves into a spherical shape. A large number of movable contact plates are inserted and supported on the movable contact mounting surface at the outer peripheral edge thereof, and are bent downwardly by pressing force from above to contact the contact portions of the lower fixed contact plate. A movable contact tape formed by arranging them in the length direction and a cover tape formed by arranging a large number of flexible cover sheets having a contact agent layer on the bottom surface in the length direction are wound on separate reels, respectively. While unwinding and feeding each tape from the reel, the lower fixed contact tape, spacer tape, upper fixed contact tape, movable contact tape, and cover tape are stacked and pressurized in the order of the lower fixed contact plate and the lower fixed contact plate. The upper fixed contact plate is bonded to the upper fixed contact plate through the spacer sheet, and the cover sheet is attached to the upper surface of the movable contact plate placed on the upper fixed contact plate and its movable contact mounting surface to form a thin push switch. are successively assembled, and then the thin push switch is cut and separated from each tape.
