Example Embodiment

[0053] Hereinafter, preferred embodiments for implementing the present invention will be described.

[0054] Such as Figure 1 to Figure 3 As shown, the cover member with a waterproof function according to the present invention is used for opening / closing the opening 11 formed in the housing 1 of the housing of the portable terminal device.

[0055] The connector 5 is arranged on the opening 11.

[0056] In addition, the lid member having a waterproof function according to the present invention includes a protrusion 21 and a sealing portion 3 made of a rubber-like elastic material. The protrusion 21 is integrally formed on one side surface of the resin material main body 2 of the lid member that opens / closes the opening 11 of the housing 1, and is accommodated in the opening 11. The sealing portion 3 made of a rubber-like elastic material is integrally formed on the outer peripheral surface 211 of the protrusion 21 and includes an annular protrusion 31 that is in close contact with...

Abstract

The purpose of the present invention is to reduce an insertion resistance of a lid member and to ensure a stable sealing performance of a sealing section. To this end, this lid member with a waterproofing function comprises: a protrusion section that is integrally formed with one surface of a main resin body of the lid member, which is used to open/close an opening section formed on a housing, so as to fit the opening section; and a sealing section that is made of a rubber-like elastic material, is integrally formed with the outer circumferential surface of the protrusion section, and has an annular protrusion that comes into tight contact with the circumferential surface of the opening section. The lid member has a configuration wherein the annular protrusion is shaped such that the diameter of the annular protrusion increases toward the inner side of the opening section, a tapered surface that converges toward the inner side is formed on the outer circumferential surface of the protrusion section, and a sealing surface with a arc-shaped cross section is continuously provided with the maximum-diameter section of the tapered surface.

Description

technical field [0001] The present invention relates to a cover member having a waterproof function for an electronic device, and more specifically, the present invention relates to a structure for sealing such that water droplets do not enter the interior of an electronic device such as a mobile phone terminal. [0002] Therefore, the cover member having a waterproof function of the present invention can be suitably utilized as a sealing structure of a connector portion of a waterproof electronic device. Background technique [0003] Conventionally, portable terminals have been provided with connector covers for opening and closing the connectors. [0004] That is, the connector cover for opening / closing the communication port for the connector is band-shaped or circular, and is fixed and held on the case (casing) side by the flexible band portion. [0005] In addition, a small rib-shaped seal ring portion is formed on the peripheral side of the connector cover of the plug...
