Description
The present invention relates to an electrical connector, and more particularly to an electrical connector having a structure that can more effectively protect a terminal from electromagnetic interference.
A connector is used for electrically connecting a circuit board and a circuit board or a circuit board and an electronic component. Generally, a plug is inserted and coupled to a receptacle, and a terminal or pins of the receptacle and a plug are electrically connected to each other , The circuit board and the circuit board or the circuit board and the electronic component are electrically connected.
In the connector having such a structure and function, a plurality of terminals are disposed so that a large amount of signals can be exchanged in a short period of time. In this case, an insulator for electrically insulating each terminal from adjacent terminals can be used. Also, a structure (e.g., a shell) that shields the terminal with a metal material is used to protect it from electromagnetic interference.
In order to shield the terminals coupled to such insulators from all directions, it may be advantageous for the shielding shell to cover the path through the terminals as far as possible. However, in order to construct such a connector, it is necessary to assemble the insulator portion and the shielding shell portion.
When the electrical connector is mounted on a circuit board, the direction in which the electrical connector is inserted for engagement may be perpendicular to the circuit board, or an electrical connector coupled to the electrical connector mounted on the circuit board may be oriented parallel to the circuit board .

The present invention solves the above-mentioned problems occurring in an electrical connector including a shielding shell and an insulator. It is an object of the present invention to provide a shielding pin and / or an auxiliary shielding part for shielding electromagnetic waves, The present invention is directed to an electrical connector.
In order to achieve the above object, an electrical connector according to the present invention includes: a shielding shell including a chamber for receiving a corresponding connector; And an insulator coupled to the plurality of terminals and associated with the shielding shell. The shielding shell is electrically grounded by the foot portion soldered to the circuit board and the shielding portion is fixed to the rear portion of the shielding shell. The shielding shell is provided at the lower portion of the chamber And at least one shielding lead extending and fixed to the circuit board.
The shielding lead comprises a support fixed to the chamber and a mounting portion extending from the support, preferably the mounting portion extends from the lower central portion of the support, the width of which is smaller than the width of the support. Here, the mounting portion of the shielding lead can be inserted into the through-hole of the circuit board with the lower end thereof disposed on the same line as the lower end of the foot portion of the shielding shell.
In addition, the mounting portion of the shielding lead may be mounted on the surface of the circuit board with a horizontal lower end portion of the mounting portion bent by bending a part of the lower portion.
Meanwhile, the electrical connector according to the present invention may further include an auxiliary shielding portion located on the outer surface of the shielding portion of the shielding shell. Preferably, the auxiliary shielding portion extends downward from the rear upper end of the chamber of the shielding shell to cover the shielding portion as a whole .
The general electrical connector according to the present invention can effectively protect a terminal from electromagnetic waves generated from a plurality of electronic components mounted on a circuit board by using a simple structure.
