Abstract

The objective of the present invention is to be able to provide a lid member with a waterproof function that can be made thinner, and wherein burr leaking can be inhibited, damages to the lid member can be eliminated, and peeling off between the lid member and a sealing section can be prevented, by having the sealing section, which is made of rubber-like elastic material, formed in integration to the lid member. Provided, in order achieve this objective, is a lid member with a waterproof function that opens / closes an opening section formed on a housing, and that is configured to be composed of: a protruding section that is formed integrally onto one face of a resin body of the lid member, and that fits into the opening section; a ring-shaped protruding section that is formed integrally onto an outer circumference face of the protruding section, and that comes in close contact with the circumferential face of the opening section; a sealing section that is made of rubber-like elastic material, and that is equipped with a reinforcement section that extends from the ring-shaped protruding section to the vicinity of a joining section between the outer circumference face and the body; and a holding section that is made of a thermoplastic elastomer material, that is formed integrally onto the body side, and that is in close contact with the outer circumference face side of the reinforcement section.

Description

technical field [0001] The present invention relates to a cover member having a waterproof function for an electronic device and a manufacturing method thereof. 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, a portable terminal has been provided with a connector cover for opening and closing the connector. [0004] That is, the connector cover, which opens and closes the communication port for the connector, is fixed and held on the case (casing) side by a belt-shaped and flexible belt portion. [0005] In addition, a small rib-shaped seal ring portion is formed on the peripheral side of the connector...
