Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency connectors, in particular to a high-frequency connector with a heat dissipation and light guiding structure arranged on a shielding cover. Background Art

[0002] The main function of a connector is to transmit electrical signals between two electrical devices. At high frequencies, the attenuation and phase delay of the connector become more significant, which will affect the signal transmission quality. In addition, at high frequencies, the connector is more vulnerable to external interference, so a shielding cover is needed to reduce the sensitivity of the connector to external interference. Existing connectors have single-port plugging or multi-port plugging. For multi-port plugging connectors, there is usually a high heat generation, and a heat dissipation structure needs to be set. In addition, the corresponding plugging female seat is usually embedded with a light-emitting diode (LED) for displaying the signal connection status. The power-on status of the connector, whether the network signal is abnormal, and whether the signal transmission of each connected device is normal can be intuitively checked through the display status of the light-emitting diode. Generally, the light-emitting diode is displayed at the rear end of the plugging female seat, and an existing light guiding member is set to guide the light to the front end for easy viewing. For existing connectors, some do not have a heat dissipation and light guiding member structure, some have a heat dissipation structure alone, some have a light guiding member structure alone, and some have both. For existing high-frequency connectors with a heat dissipation and light guiding member structure, their designs have complex assembly structures, or there is a problem that the two sides along the width direction are easily detached when buckled.
