Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, specifically a high-speed differential electrical connector. Background Technology

[0002] With the increasing application areas and requirements of electrical connectors, traditional differential connectors can only transmit high-speed digital signals independently. Especially in situations where high-speed digital signal data transmission also requires the transmission of high-frequency radio frequency video signals, the differential connector structure can no longer meet the transmission requirements of multiple signals. Existing electrical connectors that integrate differential and coaxial contacts can also support the transmission of two types of signals, but the electrical connection integration is simply arranged in two parts: one for differential contacts and the other for coaxial contacts. This results in unresolved issues regarding overall stability, mating guidance performance, and overall electromagnetic shielding performance when used in complex environments. Summary of the Invention

[0003] This invention provides a high-speed differential electrical connector with a balanced and stable structure that can take into account both overall guiding and plug-in performance and overall electromagnetic shielding performance.

[0004] The technical solution adopted by this utility model is: a high-speed differential electrical connector, including a plug and a socket, characterized in that: the plug has two or more even-numbered differential contacts and multiple coaxial contacts on its mating end face; the two or more even-numbered differential contacts are arranged in an array in the middle of the mating end face; multiple coaxial contacts are evenly distributed around the outer circumference of the arrayed differential contacts; and coaxial contacts are respectively arranged on both sides of the radial outer circumference between any two adjacent differential contacts in the array; the plug head shell is integrally provided with a connecting plate on the outer circumference of one side of the mating end; the connecting plate has multiple evenly distributed connecting holes that are connected to the socket mounting plate by screw locking; the connecting holes are oblong holes, and the direction of the oblong holes is radial to the circumference of the socket.

[0005] A coaxial contact is provided radially outward between the center position of any two adjacent differential contacts in the array.

[0006] The connecting plate is a positive-direction connecting plate, and four corresponding connecting holes are provided on the four corners of the square connecting plate, which are locked to the mounting plate of the connecting socket by screws.

[0007] The plug has three or more guide keys on the outer wall of the head housing corresponding to three or more keyways on the inner wall of the socket housing.

[0008] The included angles on the circumferences of the three or more guide keys are all different.

[0009] The three or more guide keys are distributed in four different quadrants of the circumference.

[0010] The beneficial effects of this utility model are:

[0011] 1. When the connector plate on the plug is locked to the socket mounting plate by the screw, the radially expanding waist hole on the circumference serves as the connection hole, which facilitates adjustment and fixing of the plug.

[0012] 2. The head shell has three or more guide keys with different circumferential angles, which facilitates alignment and insertion. The guide keys are distributed in different quadrants, which can improve the stability of the insertion.

[0013] 3. The differential contact array is evenly distributed in the middle of the head housing, and coaxial contacts are arranged around its outer circumference. The coaxial contacts correspond to the differential contacts outside the differential contacts, which helps to ensure the balance of the plug-in structure and improve the plug-in stability. At the same time, the coaxial contacts correspond to the corresponding directions and / or the middle positions outside the two adjacent differential contacts, which helps to improve the overall electromagnetic shielding performance.
