Abstract

Disclosed herein is an electrical connector ( 10 ) mounted on a substrate and connected to a mating connector ( 20 ). The electrical connector ( 10 ) includes: a housing including a base, a first wall ( 10 - 5 -W 1 ) protruding from an upper surface of the base and extending in a longitudinal direction of the electrical connector ( 10 ), and a second wall ( 10 - 5 -W 2 ) protruding from the upper surface of the base and facing the first wall ( 10 - 5 -W 1 ); multiple contacts ( 10 - 3 ) disposed on the first wall ( 10 - 5 -W 1 ) and the second wall ( 10 - 5 -W 2 ); and a shielding part ( 10 -S) formed around a periphery of the housing ( 10 - 5 ). The shielding part ( 10 -S) has a curved portion ( 10 -S-C) formed at an upper end of a side surface thereof and curved inwards in a transverse direction (Y-axis direction) of the electrical connector ( 10 ) and an inclined portion ( 10 -S-I) formed inside the curved portion ( 10 -S-C) in the transverse direction of the electrical connector ( 10 ) and adjoining the curved portion ( 10 -S-C).

Description

TECHNICAL FIELD The present invention relates to an electrical connector. More particularly, the present invention relates to an electrical connector for radio frequency (RF) applications, which includes a shielding part for electric field shielding. BACKGROUND Generally, interconnection between substrates is established using two connectors that are connected to respective substrates by soldering or the like and are connectable to each other. Here, one of the two connectors is a plug connector and the other is a socket connector. The socket connector is also referred to as a receptacle connector. Such plug and socket connectors may be formed by disposing terminals in a molded part (housing). The plug connector and the socket connector may be fastened to each other to form an electrical connector assembly. With the trend toward miniaturization of electronic devices, such connectors have increasingly become compact in size and height. However, there are certain limitations in making a connector compact in size and height by reducing a pitch between electrical terminals or by downsizing related components. As connectors have become compact in size, it is more difficult than before to ensure durability thereof. In addition, with recent improvement in performance of data processing devices mounted on electronic devices, such as a measuring instrument and an audio-visual (AV) device, processing of vast amounts of data in electronic devices has become possible. Accordingly, a large amount of data is transmitted and received as electrical signals at high speed through inter-board connectors. In addition, as mobile devices, such as smartphones, have increasingly become compact in size and highly functional, there is increasing demand for high-density mounting of components, such as devices and connectors, on a printed wiring board, which is leading to miniaturization of a connector itself and reduction in pitch between terminals in the connector. Under these circumstances, there is a need for a connector that exhibits desirable RF characteristics to properly transmit RF electrical signals, achieve impedance matching between multiple terminals inside the connector, reduce disturbances, such as noise/electromagnetic waves, which can occur between the connector and an outside environment. SUMMARY It is one aspect of the present invention to provide an electrical connector (10) that can prevent electromagnetic waves generated during data communication from radiating outside the connector (10) and affecting other products and can block electrical noise coming in from outside the connector (10). It is another aspect of the present invention to prevent warpage of a shielding part (10-S) of the connector (10). It is a further aspect of the present invention to determine a positional relationship between an uppermost point of a curved portion (10-S-C) of the shielding part (10-S) and uppermost points of terminals (10-1, 10-3) of a plug connector (10) to prevent the curved portion from interfering with connection between the terminals (10-1, 10-3) of the plug connector 10 and terminals (20-1, 20-3) of a socket connector (20). It is yet another aspect of the present invention to reduce the size of the shielding part (10-S) (size in a transverse direction (Y-axis direction) of the connector) in consideration of a formation angle (α) of the curved portion (10-S-C). It is yet another aspect of the present invention to secure a sufficient space around the curved portion (10-S-C) to facilitate entry of a signal terminal (20-3) of a mating connector (20) and a surrounding portion thereof (for example, an outer wall) while securing a space for formation of an inclined portion (10-S-I) described below. It is yet another aspect of the present invention to provide an inclined portion (10-S-I) that can prevent the connector (10) from being interfered with by a mating connector 20 upon disconnection (removal) of the connector from the mating connector and can guide the connector (10) to a correct connection position even when the connector (10) is slightly jammed while being fitted into the mating connector (20). It is yet another aspect of the present invention to appropriately adjust a formation angle β of the inclined portion (10-S-I) to achieve the intended effects (for example, the effects of preventing interference upon removal of the connector from the mating connector, guiding a housing (20-5) near the power terminal (20-1) of the socket connector (20) to a proper position upon connection of the connector to the mating connector, and providing sufficient rigidity to prevent warpage of the shielding part (10-S)). It should be understood that aspects of the present invention are not limited to the above. The above and other aspects of the present invention will become apparent to those skilled in the art from the detailed description of the following embodiments in conjunction with the accompanying drawings. In accordance with an a
