Electrical connector

This creation is about an electrical connector, especially an electrical connector for USB TYPE C.

The universal serial bus (hereinafter referred to as USB) specification electrical connector is one of the most widely used transmission interfaces in daily life. Due to the convenience and convenience of the USB interface, small size and reasonable cost, it is used in different jobs. USB traces can be seen everywhere in the field. 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, because the USB Type C interface has a large number of conductive terminals and the volume is also small, how to overcome electromagnetic interference (EMI) in a limited space will be an urgent problem to be overcome.

It can be seen that there are still many shortcomings in the above-mentioned conventional structure, which is not a good designer, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional structure, the creators of this case have improved and innovated, and after years of painstaking research, they finally successfully developed and completed the electrical connector.

The purpose of the present invention is to provide a first component and a second component that are snap-fitted to each other through the barb structures on both sides of the first body and the second body, so as to cover the insulating body and achieve a stable connection.

Another object of the present invention is to provide a first cover body and a second cover body on the insulating cover body that can be assembled and overlapped with the shielding case, so that the first cover body and the second cover body can shield the absorbed static electricity from being shielded. The housing is exported to reduce signal interference.

In order to achieve the above object, the electrical connector of the present invention is configured to transmit a high frequency signal, comprising a first component, a second component, an insulative housing, a shielding plate disposed on the insulative housing, and surrounding the first component and the The shielding shell of the outer edge of the two components.

The first component includes a first body and a first terminal fixed to the first body, wherein the left and right sides of the first body respectively extend toward the bottom end with a hook with a hook portion; the second component The second body includes a second body and a second terminal fixed to the second body, wherein the left and right sides of the second body respectively extend toward the bottom end with a hook portion with a hook portion; the first body and the second body The side barbs are corresponding and inverted, so that the first component and the second component can be fastened and fixed to each other through the barbs on both sides, thereby wrapping the insulating bodies and snapping them to each other to achieve the creation. The purpose.

In order to achieve the above other object, after the first component and the second component of the present invention are fastened by the buckle, the front end cover is covered in an insulating cover body to form a docking connector for docking, and the mating connector The upper cover and the lower cover of the insulating cover are covered with a first cover body and a second cover body. The first cover body and the second cover body extend outwardly with an elastically deformable elastic portion. After the first component, the second component and the insulating cover are covered, the elastic portion interferes with and contacts the inner edge of the shielding shell, so that the electrical connector generates static electricity when transmitting the high frequency signal. The electric power can be transmitted to the shielding shell through the first cover body and the second cover body respectively, and the other purpose of the creation is achieved.
