Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0048] figure 2 The lower body 5 of the mobile phone with the key switch in the embodiment of the present invention is shown. The lower body 5 has an operation portion 4 on its surface. As the operation part 4, a plurality of operation keys 7 such as 0-9 number keys and function keys are arranged on it. In addition to these operation keys 7 , side keys 20 are provided on the side of the lower body 5 .

[0049] Such as image 3 As shown, the lower body 5 includes a surface-side case 5a and a rear-side case 5b. The rear side case 5 b covers the rear side of the front side case 5 a , houses a rechargeable battery 9 therein, and is provided with a battery cover 10 covering the rechargeable battery 9 . A main substrate 11 constituting the operation unit 4 and a flexible substrate 12 covering the surface of the main substrate 11 are provided on the front side case 5 a a...

Abstract

The invention discloses a method for manufacturing a key switch. Insert the end of the push member (25) on the keycap side into the recess of the lower die for the push member on the surface of the lower die, and place the reinforcement plate (28) in such a way that the push member (25) passes through the through hole on the plate side of the reinforcement plate (28). On the lower die, insert the other end of the push member (25) into the recess of the upper die for the push member provided on the lower surface of the upper die, so that the upper die and the lower die are close to each other, and the Liquid silicone rubber (27), which is a component that is bonded to the push member (25), is injected into the cavity, pressurized at a specified temperature and kept for a specified time, then the mold is opened, and the axial middle part of the push member (25) is taken out The molded product supported in the plate side through hole by silicone rubber (27), the back side of the key cap (26) is installed on the key cap side end of the molded product push-up member (25). Thereby, the pushing member and the reinforcing plate can be integrally formed using the elastic member easily and reliably, and the durability of the key switch can be improved.

Description

technical field [0001] The invention relates to a method for manufacturing a key switch used in electronic equipment such as mobile phones. Background technique [0002] Electronic devices with waterproof structures, such as watches and mobile phones, have been used until now. For example, a key switch on an electronic device having a waterproof structure as in Patent Document 1 has a fixed structure portion and an operating body attached so as to be able to enter and exit from the fixed structure portion. The operating body is provided with a sliding portion configured to be slidable relative to the fixed structure portion, and an operating head portion connected to the outside of the sliding portion and having a bulging shape having a larger diameter than the sliding portion. In addition, a tubular elastically deformable elastic member held between the bulging portion of the operation head portion and the fixing structure portion and surrounding the sliding portion is pro...
