Description

Electrical connector and cover having the same

The present invention relates to an electrical connector, and more particularly to an electrical connector that is electrically connectable to a circuit board.

The universal serial bus (hereinafter referred to as USB) specification of the electrical connector structure is one of the most widely used transmission interfaces in daily life. Due to the convenience and ease of use of the USB interface, small size and reasonable cost, it is different. USB traces can be seen everywhere in the work area. Whether it is the family's core entertainment devices such as TVs, personal notebooks, smart phones, tablet devices or office work computers, printers, and even multimedia communication entertainment systems for cars, they often rely on USB for data. The task of transmission.

In addition to providing convenient, fast and reliable data transfer, USB has a very convenient function, which is the transmission of power through the interconnection of multimedia electronic devices, which is called charging. However, the current USB charging can only provide up to 7.5 watts of power. This evolution of power supply specifications can meet the charging requirements of handheld portable devices such as mobile phones or music media players (MP3), but it usually takes more time. It is a bit too short to be able to meet the large size and consume power from a larger power product such as a screen monitor or a notebook computer.

In order to more popularize the application of USB in different device power supply, and to provide portable electronic products with convenient and thinner, and reduce the wrong direction of USB insertion or wiring direction In the case of untransmission, the new universal serial bus Type C came into being. The USB International Standards Association (USB-IF) has announced the standard specification for the USB Type C interface, which is designed to allow a variety of devices to be powered by a single USB cable with a power transfer of up to 100 watts. The need to reduce the charging time of the device makes it easier to optimize the convenience of mobile applications.

In addition, the USB Type C interface will support a new ultra-thin design for a wide range of devices, from mobile phones, tablets, 2-in-1 products, notebooks to desktops and many other more specific devices.

This thin interface adopting the new industry standard can transmit data, power and video, and will become the only interface required for people to combine various devices. Due to the large increase in the amount of data transmitted, corresponding electromagnetic radiation may be generated during use. In order to interfere with the normal operation of other electronic components, in view of this, the industry generally uses grounding to reduce the generation of electromagnetic interference (EMI).

However, the USB Type C interface has a large number of conductive terminals and a small volume, in addition to how to overcome electromagnetic interference (EMI) in a limited space, how to solve the problem of a large number of terminals Stable production and assembly will be an issue that this product needs to overcome.
