Problems solved by technology

[0013] Due to the miniaturization of the connector cover, and the insertion amount of the waterproof cover member relative to the opening 11 cannot be ensured sufficiently, there will be a problem that the cover member is pushed back and cannot be closed.
[0014] Therefore, although an attempt was made to reduce the amount of contact between the sealing portion 300 and the peripheral surface 12 of the opening 11 (compression allowance of the sealing portion 300), the contact pressure of the sealing portion 300 with respect to the peripheral surface 12 decreased, making it difficult to ensure stable sealing performance.

Embodiment Construction

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

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

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

[0056] In addition, the cover member having a waterproof function according to the present invention includes the protrusion 21 and the sealing portion 3 made of a rubber-like elastic material. The protrusion 21 is integrally formed on one side of the main body 2 made of resin material of the lid member that opens / closes the opening 11 formed in the case 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 protruding portion 21 , and includes an annular protrusion 3...

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...
