Socket connector

Abstract

The invention provides a socket connector which utilizes a reinforced metal component for protecting a contact with outside forces and can reliably and electromagnetically shield the flowing contact of high-frequency signals. On the reinforced metal component with a reinforcing cover covering one part of the surface of a protruding plate part, a contact pad exposed out of one part of the outer periphery of a housing main body is integrally formed, and is contacted with a shielding housing metal component along the outer periphery of housing main body.

Description

technical field [0001] The present invention relates to a receptacle connector, wherein the periphery of the protruding plate part where a plurality of contacts are exposed is covered by a cylindrical shielding shell metal part, and the opposite side pin is fitted and connected to the fitting recess between the protruding plate part and the shielding shell metal part , in more detail, relates to a receptacle connector that electromagnetically shields a plurality of contacts with a ground-connected shield shell metal part. Background technique [0002] A receptacle connector for high-speed signal transmission such as a USB connector used in the USB (Universal Serial Bus) standard for connecting a host device and a peripheral device, and the surrounding of the projecting plate part where the contact is exposed is covered with a cylindrical shielding shell metal Parts are covered to block the contacts through which high-frequency signals flow from the outside.

Problems solved by technology

[0009] According to this conventional receptacle connector 100, there is the following problem: Since the periphery of the contact 103 through which the high-frequency signal flows is surrounded by the shield shell metal part 104 set to the ground potential, it is electromagnetically shielded, but passes through the opposite side of the connection. In such a way that the pin is not easy to pull out, the cylindrical shielding shell metal part 104 is provided with a matching hole for matching with the opposite side pin and a matching protrusion cut and erected from a part of the shielding shell metal part 104, and these matching parts are formed, so that the shielding Openings are formed in a part of the shell metal fittings 104, and the fitting recess 105 is opened in a state where the opposite side plug is not connected, and through these openings, noise enters from the outside or a high-frequency signal generated to flow through the contacts 103 is exposed to the outside. of unwanted radiation

[0010] In addition, on the above-mentioned receptacle connector 100, a reinforcing metal part 101 is installed to protect the protruding plate part 102 and the contact 103 from the wrongly inserted opposite side pin, and to apply external force to the leg part 103a of the other contact 103. The leg portion 101b is fixed to the printed circuit board, but the metal plate is used mainly to act on the mechanical external force, and it is not electrically connected to any of them, and becomes an unstable potential

Since the reinforcing metal parts 101 of this unstable potential are arranged close to the contacts 103, the characteristic impedance of the high-frequency transmission line flowing through the contacts 103 becomes unstable and the transmission efficiency deteriorates.

[0011] If the leg portion 101b of the reinforcing metal part 101 is soldered to the ground pattern that is the ground potential, the characteristic impedance can be stabilized by using the reinforcing metal part 101 as the ground potential, but it is necessary to form the leg part on the reinforcing metal part 101 101b, and it is necessary to dispose the ground pattern at a position different from the connection position of the shielding case metal part 104, thereby causing a new problem of lowering the mounting density of the printed circuit board

[0012] In addition, when the shielding case metal part 104 and the reinforcement metal part 101 are connected through the ground pattern on the printed circuit board, the conductive path connecting the two becomes long, and a potential difference may occur due to high-frequency disturbance flow, which may not be sufficiently obtained. shielding effect
