Sealing shell for connector and electrical connector

Abstract

The invention provides a sealing shell for a connector and an electrical connector, which can reliably prevent water from intruding from the joint part of the sealing shell due to capillarity. The sealing shell of a connector is inserted into the outer circumferential wall of an electrically-insulating connector housing provided with an electrical connector contact for electromagnetic shield. The sealing shell (1) for the connector is formed into a tubular shape in a way to bend a metal sheet material with a preset size and thickness in a tubular way so as to form inside a hollow hole (12) capable of making the connector housing inserted and make the two ends of the metal sheet material docked. Laser bonding is performed on the docked joint part (1b'). At least one end is made open.

Description

technical field [0001] The present invention relates to a sealing case for a connector and an electrical connector. More specifically, it relates to a sealing case for a connector in which the sealing case for a connector has a waterproof structure and a waterproof electrical connector using the sealing case. Background technique [0002] In recent years, electronic information devices such as personal computers, mobile phones, and information terminals have rapidly spread. These electronic information devices incorporate various types of electrical connectors (hereinafter referred to as connectors) for connection with external devices and the like, however most of them are connectors conforming to the USB standard. Such connectors usually use a sealed shell to cover the insulating shell with contacts for electromagnetic shielding, so as to prevent noise from invading from the outside to the inside, causing obstacles to the electronic circuits in the electronic equipment, an...

Problems solved by technology

However, even if such a waterproof technology is applied, it cannot withstand use in the above-mentioned too harsh environment, and in particular, cannot prevent water immersion caused by capillarity.

That is, for a connector incorporated into an electronic information device, a part of the connector, particularly a front end portion of the sealing case, is exposed from the housing of the electronic information device, and it is very likely that a part of the connector will penetrate from the exposed portion due to capillary action.
