Improvement of grounding structure of electrical connector

The present invention relates to an improvement in the grounding structure of an electrical connector, and more particularly to an improved grounding structure of an electrical connector that can simplify the manufacturing of components and assembly procedures while improving the grounding performance of the electrical connector.

Universal Serial Bus (hereinafter referred to as USB) specification connector is one of the most widely used transmission interfaces in daily life. Due to the convenience and ease of use of USB interface, small size and reasonable cost, it is used in different workplaces. USB traces can be seen everywhere in the domain.

Whether it's a 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 connectors. The task of data transfer.

In order to more popularize the application of USB in the power supply of different devices, and to provide multimedia electronic products that are convenient to carry and lighter and thinner, and to reduce the inability to transmit due to the wrong direction of USB insertion or wiring, the new universal serial bus type C It 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.

In order to solve the above problem, the USB TYPE C interface is designed with a grounding piece structure between the line end connector and the board end connector, and when the line end connector and the board end connector are connected to each other, the line end connector is grounded. The elastic arm of the piece is clamped with the board end connector to eliminate electromagnetic interference; please refer to the Republic of China new patent No. M491281, which discloses a grounding improved structure of the connector, wherein the grounding piece and its elastic grounding arm The utility model relates to a flat structure, in particular to a blanking process. However, when the elastic grounding buckle arm is continuously reciprocating elastically deformed, the supporting force of the supporting point due to the elastic deformation is insufficient, so that the elastic fatigue is prone to occur, and further The grounding piece of the board-end connector cannot be snap-fitted to each other, resulting in insufficient stability to eliminate electromagnetic interference.

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 have successfully developed and improved the grounding structure of the electrical connector.

The purpose of this creation is to provide a grounding strip structure for an electrical connector that increases the elastic clamping life of the grounding plate resilient arms.

Another object of the present invention is to provide a grounding strip structure of an electrical connector that stabilizes the grounding conduction effect of the electrical connector and the mating connector.

In order to achieve the above object, the grounding structure of the electrical connector of the present invention is improved, comprising: a first insulating body; a second insulating body corresponding to the first insulating body; and being disposed and fixed to the first insulating body And a grounding piece between the second insulative housing, the grounding piece includes a flat portion received between the first insulative housing and the second insulative housing, and a soldering portion is extended on both sides of the rear end of the flat portion to make it solderable On the circuit board, a flexible arm is bent toward the front end of the flat portion, and a front end of the elastic arm extends toward the inner edge, wherein the elastic arm and the flat portion are bent into a continuous bending portion. The structural strength of the elastic arm is increased by the bending portion, thereby providing sufficient clamping force of the elastic arm and stabilizing the grounding effect of the electrical connector.

Compared with the conventional structure, the elastic grounding buckle arm of the flat portion of the conventional electrical connector is extended or bent from the flat plate portion. When the elastic grounding buckle arm and the mating connector are butted and clamped to each other, the elastic grounding is performed. The clamping force of the buckle arm is only supported by the extension or bending distance between the flat plate portion and the elastic grounding buckle arm, and cannot effectively support the elastic deformation clamping of the reverse; in contrast, between the elastic arm and the flat portion of the creative electrical connector, Forming a continuous bend, the continuous bend provides a clamping force for reversing elastic deformation, providing sufficient clamping force and stabilizing the grounding effect of the electrical connector fruit.
