Description

Electric connector with electromagnetic shielding function

This creation is about an electrical connector, especially an electrical connector that can prevent electromagnetic interference inside and outside the electrical connector and has an electromagnetic shielding function.

Conventional connectors refer to connecting components and accessory parts used for electronic signals. Cables and connectors are used to convert and transmit signals between electronic devices. In other words, connectors are also bridges between signals. Connectors are widely used in automotive and computer peripheral applications, communication data applications, industry, military aerospace, transportation, consumer electronics, medical treatment, instruments, commercial equipment, etc. Therefore, connectors play an important role in many fields. In this information-developed and efficient generation, the transmission speed of signals continues to move toward high-speed development. Therefore, high-frequency connectors have also been developed to increase the signal transmission rate.

Generally speaking, the higher the frequency of the signal carried by the connector, the more likely it is to be affected by internal or external factors, such as Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI). The connector will suffer from electromagnetic interference or radio frequency interference, resulting in incomplete signals, which further affects the transmission quality. In addition, with the development of the electronics industry, electronic products have a trend of miniaturization. Therefore, the wires inside the connector The distance between the cables is getting closer. As the distance between the cables is reduced, it is not conducive to the transmission of high-frequency signals, so it is easy to cause crosstalk between high-frequency differential cables. Due to the above-mentioned interference reasons, the signal transmission characteristics of the connector are actually affected.

In order to prevent electromagnetic interference inside and outside the electrical connector, the outer layer of the wire core of the cable is usually covered with an insulating layer, and then the insulating layer is covered with a metal mesh to form a shielding layer. The main function of the shielding layer is to shield the electromagnetic field generated when the cable is energized in the insulated core to reduce electromagnetic interference to the outside world. However, when the cable is connected to the circuit board of the electrical connector, the cable needs to remove the shielding layer and the insulating layer to expose the wire core, and then solder the wire core to the circuit board. At this time, there is no shielding layer between the cores of the cables, which may still cause crosstalk between the cables. In addition, the stripped shielding layer may be exposed to the outside of the cable, so that the shielding layer has a great impact on the resistance and insertion loss of the cable, thereby reducing the transmission quality of the cable.

Therefore, it is necessary to develop an electrical connector that can prevent electromagnetic interference inside and outside the electrical connector to solve the problems of the prior art.

In view of this, this creation provides an electrical connector with electromagnetic shielding function. In a specific embodiment, the electrical connector with electromagnetic shielding function includes a circuit board, a plurality of cables, and a shielding member.

One end of the wire core extends from the shielding layer to be exposed, and the wire cores of the cable are respectively electrically connected to the conductive solder pads. The shielding member is arranged on the circuit board and is electrically connected to the ground element. The shielding member forms a plurality of shielding grooves so that the conductive pads and cables are respectively located therein. Each shielding groove includes a contact portion and a shielding portion extending from the contact portion. The contact parts of the shielding groove respectively contact the shielding layer of the parallel-connected cable and shield the groove The shielding parts respectively cover the exposed cores of the cables to electromagnetically shield the cables.

Wherein, the shielding member includes a plurality of rib structures respectively disposed at the contact portions of the equal shielding grooves. The rib structure is used to respectively contact the shielding layer of the cable.

Wherein, the shape of the contact portion of the shielding groove corresponds to the shape of the shielding layer of the cable.

Wherein, the conductive pad includes a first conductive pad and a second conductive pad, the cable includes a first cable, and the first cable includes a first core and a second core. The first conductive bonding pad and the second conductive bonding pad are located in the first shielding groove of the shielding groove, and the first wire core and the second wire core are respectively connected to the first conductive bonding pad and the second conductive bonding pad.

Wherein, the shielding member includes a plurality of protruding structures arranged in the shielding part of the shielding groove. The protruding structures are respectively located between two adjacent cables of the cables.

Further, the grounding element includes a plurality of grounding pads. The number and positions of the grounding pads correspond to the number and positions of the protruding structures, and the protruding structures are respectively connected to the grounding pads.

Wherein, the shielding member includes a first side wall and a second side wall. The first side wall and the second side wall are opposite to each other and the shielding grooves are located between the first side wall and the second side wall. The length of the first side wall and the second side wall is less than the length of the protruding structure.

In a specific embodiment, the grounding element is a grounding layer, and the shielding member is electrically connected to the grounding layer by one of riveting and snapping.

Wherein, the material of the shielding member is selected from one of metal and conductive plastic.

Wherein, the shielding member includes a third side wall located at the shielding portion and connected to the shielding grooves, so that the shielding portion completely covers the wire core of the cable and the shielding member does not contact the wire core.

In summary, the electrical connector with electromagnetic shielding function of the present invention can simultaneously cover the core of the cable through the shielding member and contact the shielding layer of the cable to provide electromagnetic shielding effect. And thus improve efficiency. In addition, the electrical connector of the present invention can separate two adjacent cables through the protruding structure of the shielding member and produce an electromagnetic shielding effect, so as to prevent the crosstalk between the cables inside the electrical connector, thereby improving the electromagnetic shielding efficiency. Furthermore, the shielding member of the electrical connector of the present invention can contact the shielding layer of the cable in various ways to respond to cables of different wire diameters, thereby improving efficiency. In addition, the electrical connector of the present invention can cover the core and shielding layer of the cable through the shielding member, so as to prevent the cable of the electrical connector from being electromagnetically interfered by other external electronic components, thereby improving the transmission quality and efficiency.
