Abstract

The present invention relates to a shielded connector device capable of obtaining an improved shielding effect with a simple structure. Since a plug shield member and a receptacle shield member are electrically contacted only by male and female coupling between a contact rib and a contact groove, the plug shield member and the receptacle shield member have a simple structure. The receptacle shield member can be electrically contacted, and the shielding function is improved due to the line contact structure between the contact rib and the contact groove.

Description

Shielded connector device {CONNECTOR APPARATUS WITH SHIELDING FUNCTION}

The present invention relates to a shielded connector device, and more particularly, to a shielded connector device capable of obtaining an improved shielding effect with a simple structure.

In recent mobile devices such as cell phones and digital cameras, various electrical and electronic components including PCB circuit boards are installed therein, and the configuration of these electrical and electronic components to be electrically connected to each other is very important for miniaturization and thinness. It is a factor to be considered. In particular, various types of board-to-board (BtoB) connectors have been developed in order to solve the space utilization problem caused by the mounting of multiple components inside portable devices.

In such connectors, data processing speed and transmission speed are gradually increasing due to the improvement of performance of portable terminals such as smart phones, and with the high functionality of portable terminals, not only the requirement to minimize the mounting area of the connector, but also high-frequency electrical signals, There is a demand for a connector that allows transmission without noise or loss and shields confusion such as modulation that may occur between a plurality of terminals.

The plug connector 10 includes a plug housing 21 , a connector body 20 having terminals 23 and 24 arranged on the plug housing 21 , and a plug shield member 30 formed to surround the plug housing 21 . ) is included. A plurality of elastic contact pieces 35 are formed in the plug shield member 30 to be inclined inward. The receptacle connector (60) is configured by attaching a receptacle shield member (70) to a receptacle housing (61) holding terminals (65, 65). And, when the plug connector 10 and the receptacle connector 60 are coupled, they are configured to be electrically connected to the receptacle shield member 70 opposite to the plurality of elastic contact pieces 35 by elastic contact.

Such a conventional connector has a problem in that the structure becomes very complicated because a plurality of elastic contact pieces 35 having a complicated structure must be provided in order for the plug shield member 30 and the receptacle shield member 60 to electrically contact each other. In addition, the elastic contact piece 35 is in point contact with the receptacle shield member 60, and such a point contact structure has a problem in that the contact area is small and the shielding effect is deteriorated.
