Plug connector and electric connector combination

Abstract

The invention provides an electric connector combination which comprises a plug connector and a socket connector, wherein the plug connector and the socket connector are in butt joint. The plug connector comprises a plug body, a sub circuit board which is accommodated in the plug body and a cable which is electrically connected with the sub circuit board. The plug body has a matching surface. The sub circuit board has a tongue board which protrudes out of the matching surface toward the socket connector and a number of conductive films which are arranged on the surface of the tongue board. The socket connector comprises a socket body and a number of elastic terminals which are accommodated in the socket body. The socket body has a butt joint part and an insertion slot which is concavely arranged on the butt joint part to accommodate the tongue board. The plug body has two side walls which protrude from the matching surface toward the socket connector and are located on left and right sides of the tongue board. Two side walls are located on left and right sides of the butt joint part to limit left and right swinging of the plug connector.

Description

technical field [0001] The invention relates to a plug connector and an electrical connector combination, in particular to a plug connector and an electrical connector combination for transmitting high-frequency signals. Background technique [0002] Universal Serial Bus (USB) has been widely used in various electronic products. Jointly formulated by International Business Machines Corporation), Microsoft (Microsoft), and Northern Telecom (Northern Telecom Corporation), it has developed from USB 2.0 to USB 3.0. USB 3.0 has ten times the transmission speed of USB 2.0 and higher energy-saving efficiency. In the future, Will be more widely used in PC peripherals and consumer electronics. [0003] For the prior art related to this case, please refer to the electrical connector combination disclosed in the Chinese patent CN 202159800U announced on March 7, 2012. It includes a plug body and a sub-circuit board located in the plug body. The plug body is provided with a mating sur...

AI Technical Summary

Problems solved by technology

[0004] When the plug connector is inserted into the socket connector forward, the tongue plate is accommodated in the slot, the conductive piece on the tongue plate and the contact part of the elastic terminal contact each other, and the positioning plate is supported upward on the bottom surface of the socket connector to play a supporting role. With the function of guiding, the locking arm and the locking block are locked together to limit the front and rear disengagement of the plug connector and the socket connector. However, in the left and right directions, the plug connector and the socket connector are relatively loose and loose, resulting in the plug connection The connector is easy to swing left and right, which affects the contact reliability between the conductive sheet on the tongue plate and the elastic terminal, thus affecting the electrical connection between the plug connector and the socket connector
