Electrical connector structure

This creation relates to an electrical connector structure, and more particularly to an electrical connector structure for USB TYPE C.

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, 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 succeeded in research and development of the electrical connector structure.

The purpose of the present invention is to separately embed the first conductive terminal and the second conductive terminal in the first insulative housing and the second insulative housing, and then assemble each other to reduce the manufacturing cost.

Another purpose of the present invention is to overlap the first shielding shell through the central grounding piece to effectively eliminate static electricity.

In order to achieve the above object, the electrical connector structure of the present invention comprises a first insulative housing, a first conductive terminal, a second insulative housing, a second conductive terminal, a first grounding strip, a second grounding strip, and a central grounding. The first insulative housing includes a base portion and a tongue extending from the base portion, the central grounding piece is disposed in the tongue piece, and the central grounding piece is embedded in the tongue piece, and the front end thereof The outer edge is exposed outside the tongue, and the contact portion of the rear end is exposed on both sides of the rear end of the base; the first conductive terminal and the second conductive terminal are respectively formed with a fixing portion and a contact portion extending from both sides of the fixing portion. And the soldering portion is respectively fixed in the first insulative housing and the second insulative housing through the fixing portion, so that the contact portion and the soldering portion are respectively exposed outside the first and second insulating bodies; the first grounding strip and the first grounding strip The two grounding strips are respectively assembled on the first insulative housing and the second insulative housing; the shielding housing encloses the component; wherein the bottom of the first insulative housing is provided with a receiving slot and the second insulating The first and second insulating bodies can be disposed after the first conductive terminal and the second conductive terminal are embedded and embedded in the first insulating body and the second insulating body.
