1. Field of Invention
The present disclosure relates to a connector. More particularly, the present disclosure relates to an electrical connector assembly with a grounding structure.
2. Description of Related Art
Information technology is a booming industry in recent years, and the amount of electronic data transmitted between electronic devices keep increasing. To transmit large amount of electronic data within a short period of time is a developing trend of present information technology. Besides increasing electronic signal transmission channels between connecting electronic devices, general measure of the aforesaid problem is to increase the electronic signal frequency between connecting electronic devices for now. For example, USB 3.0 interface is an information transmission interface with the characteristics of high speed and high bandwidth. This interface has gradually spread to all information products. In addition, the USB connector is a communication bridge of electronic signals between various electronic devices, raising the requirements of the amount of electronic data transmission, and the USB connector is gradually facing the challenge of increasing high frequency signals. Generally speaking, a cable end connector with USB 3.0 specification usually employs a plurality of cables to electrically and mechanically connect to a receptacle connector.
To follow the trend of size reduction in the production of electronic devices, the whole size of the connector is forced to shrink, so as the pitch between conductive terminals become smaller and smaller, which implies that quantity of conductive terminals inside an unit area is increased. That is, electromagnetic interference becomes greater inside the connector. In order to protect the electronic connector from the effects of electromagnetic interference, traditionally the metal housing of connector usually is connected to a grounding circuit or equipment, so that effect of the noise inducing by cables would be diminished.
A practical example of prior art is provided by United States Patent No. 2014/0220827. The reference provides an electronic connector to match to a plug connector and be disposed on a circuit board. The electronic connector includes a insulating housing and a front tongue piece. Two rows of metal terminals are accommodated inside the insulating housing and a shielding plate is inserted between two rows of metal terminals. The shielding plate includes one or more grounding finger and a grounding leg, in which the grounding leg is connected to printed circuit board (PCB), and each grounding finger is disposed between two adjacent differential signal terminal pairs and parallel to a contact portion of the terminal. The reference provides an embedded shielding plate disposed inside the inner of the electronic connector to practically function as a grounding circuit for metal terminals of electronic connector. When the plug connector is inserted to the electronic connector of this reference, the shielding plate and grounding equipment of the plug connector are unable to reach the embedded shielding plate to connect, so that electric charges from the plug connector is also unable to reach the grounding, which may lead to lessen electromagnetic interference.
Therefore, to design an electrical connector assembly with a grounding structure is in need. The present disclosure is able to fulfill this need.
An aspect of the present disclosure is to provide a connector having a grounding structure.
According to a main embodiment of the present disclosure, the present disclosure provides a main connector including a shield housing, an insulated body, a plurality of metal terminals, and a shielding plate. The shield housing has an opening for a butt joint connector to insert. The insulated body is encapsulated inside the shield housing. Each of the metal terminals has a contact portion and a fixing portion. The contact portion is arranged in two rows inside the opening of the shield housing, and the fixing portion is fixed to the insulated body. The fixing portion has at least one elastic arm with bending formation. The shielding plate is disposed between two rows of the metal terminals. The shielding plate has at least one elastic arm with a bending formation and is disposed between two rows of the metal terminals.
The disclosure can be more fully understood by reading the following detailed description of the embodiment, with reference made to the accompanying drawings as follows:
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
It will be understood that, although the terms first, second, third etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.
The following embodiments are disclosed with accompanying diagrams for detailed description. For illustration clarity, many details of practice are explained in the following descriptions. However, it should be understood that these details of practice do not intend to limit the present invention. That is, these details of practice are not necessary in portions of embodiments of the present invention. Furthermore, for simplifying the drawings, some of the conventional structures and elements are shown with schematic illustrations.

In the present embodiment, the first metal terminals 330 are formed by insert molding inside first slots 420 of the plastic base 400, and the second metal terminals 930 are formed by insert molding inside second slots 440 of the plastic base 400.
Besides, the circuit board 700 further includes grounding pads 740 located at the front ends of the upper surface and the lower surface of the circuit board 700, and the first shielding plates 600 includes an extending portion 620. The extending portion 620 is stretched out from the rear part of the first shielding plates 600 to contact the grounding pads 740. Electrical charges on the first shielding plates 600 are able to be grounded thereby the foresaid path. In addition, the first shielding plate 600 further includes a pair of elastic arms 640 respectively disposed on the opposite broadsides of the first shielding plates 600 and stretched out. The elastic arms 640 are respectively located on both sides of the first metal terminals 330 and the second metal terminals 930, and the structure of outreach end of the elastic arms 640 is partly bent to form a coupler.

In addition, two opposite broadsides of the second shielding plate 820 has two grooves 825 respectively located at two opposite broadsides of the second shielding plate 820. The second shielding plate 820 further includes a pair of grounding legs 824 disposed at two opposite corners on the back end of the second shielding plate 820.
Referring to
Summarized from the above, the present disclosure provides an electrical connector assembly including a plug connector and a receptacle connector. The plug connector includes a first metal housing and a first main body, and the receptacle connector includes a second metal housing and a second main body. The first main body includes an elastic arm contacting a groove located at a broadside of the second shielding plate in the receptacle connector, such that electromagnetic interference and noise of the plug connector are able to be diminished rapidly through the second shielding plate in the receptacle connector. Therefore, the electrical connector assembly of the present disclosure can provide a discharge path for the shielding plate discharging.
