Description

  The present invention relates to a connector such as a Micro-USB connector and a USB connector, and more particularly to a connector having a waterproof function.

  Conventionally, a portable electronic device terminal such as a mobile phone or a smartphone is connected to a peripheral device such as a charger or an external device such as a personal computer from a receptacle in which a plug is detachably connected, such as a micro-USB connector. A connector is used.

  This type of receptacle is supported by a housing having a plug insertion portion into which a plug is inserted and a tongue-like terminal support portion disposed in the plug insertion portion, and a contact portion exposed on the surface of the tongue-like terminal support portion. And a plurality of receptacle-side contact terminals that are incorporated in the electronic device in a state in which the opening of the plug insertion portion is exposed to the outer surface of the electronic device casing (see, for example, Patent Document 1).

  Then, by inserting the plug from the outside of the electronic device into the plug insertion portion where the opening is exposed on the outer surface portion of the electronic device casing, the contact portion where the plug-side contact terminal of the plug is exposed on the surface of the tongue-shaped terminal support portion So that the plug and the receptacle are electrically connected.

  Further, in this type of connector, the housing is provided with a shield member made of a conductive metal material arranged so as to surround the tongue-like terminal support portion, and exhibits an electromagnetic shielding property by grounding the shield member. It has a structure that blocks noise.

  On the other hand, this type of connector may be exposed to a harsh environment depending on the usage mode of the portable electronic device terminal. For example, the connector may be exposed to water or the like in the plug insertion part due to use in a hot and humid place or user sweat. There is a risk that liquid may enter and the liquid such as water may adversely affect the structure inside the electronic device.

  Therefore, in this type of connector, the metal shield member and the receptacle-side contact terminal constituting the receptacle are integrally molded into a synthetic resin mold member by insert molding, so that the mold part of the housing and the metallic part are integrated. Some have been developed that have a waterproof structure that eliminates the gap and prevents water from entering the electronic device from the plug insertion portion (see, for example, Patent Document 2).
