Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to an electrical connector that supports radio frequency transmission. Background Technology

[0002] The design of RF connectors should take into account conversion loss, return loss, and isolation. Isolation measures the ability of an RF isolator to prevent signal reverse transmission. It reflects the performance of RF signal transmission between the plug and connector, and determines the degree of interference the signal is susceptible to during transmission. RF isolation is generally between 10dB and 50dB. Higher isolation means that the reverse-transmitted signal is attenuated better, thus protecting the signal source and other sensitive components from interference. Ensuring high and stable isolation is a problem that connectors in the RF field need to solve. In addition, the mechanical tightness of the connector should also be considered to ensure uninterrupted signal transmission. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an electrical connector that supports radio frequency transmission.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an electrical connector supporting radio frequency transmission, including a rectangular insulating base, terminals assembled with the insulating base, and positioning posts assembled with the insulating base. The insulating base is provided with a socket, and the terminals are interference-fitted with the sockets. The terminals include power terminals and radio frequency terminals with the same structure. The power terminals are arranged in two rows and the number is set to an even number. The power terminals are distributed in two rows on the insulating base. The radio frequency terminals are arranged in three rows and the number is set to an odd number. Two rows of the radio frequency terminals are flush with the power terminals, and the other row of the radio frequency terminals is arranged between the two rows of power terminals. The terminal spacing of the power terminals and the radio frequency terminals in the length direction of the insulating base is the same.

[0005] Preferably, the terminal includes a U-shaped body, a terminal plug-in portion fixedly connected to one end of the U-shaped body, and a terminal connecting portion fixedly connected to the other end of the U-shaped body. The U-shaped body includes a first wall, a second wall connected to the first wall, and a third wall connected to the second wall. The terminal plug-in portion is fixedly connected to one end of the second wall. The terminal connecting portion includes a first elastic arm and a second elastic arm fixedly connected to the first wall and the third wall respectively, and an extension arm fixedly connected to the other end of the second wall. The first elastic arm and the second elastic arm are respectively provided with positioning grooves that stop at the bottom of the U-shaped body between them and the extension arm.

[0006] Preferably, the U-shaped body has a first opening facing the side, a second opening facing upward, and a third opening facing downward. The terminal plug-in portion is fixedly connected to the second opening. The first elastic arm, the second elastic arm, and the extension arm are fixedly connected to the third opening. The first wall and the third wall are provided with positioning portions facing the first opening. The terminal plug-in portion includes a horizontal portion fixedly connected to the end of the second wall and a vertical portion fixedly connected perpendicularly to the horizontal portion. The horizontal portion extends toward the first opening.

Positioning steps facing the upper side are provided on both sides of the U-shaped blind hole in another direction. The square through hole is limited between the two positioning blind grooves.

[0008] The beneficial effect of this utility model is to provide an electrical connector that supports radio frequency transmission. The distance between the radio frequency terminal flush with the power terminal and the intermediate radio frequency terminal is specific and consistent, resulting in high isolation between the radio frequency terminals and better attenuation of the reverse-transmitted signal, thereby protecting the signal source and other sensitive components from interference. The U-shaped body of the terminal is assembled into the U-shaped blind hole, and the second and third openings communicate with the square through hole. The positioning step is defined in the positioning groove and abuts against the bottom of the U-shaped body. The first and third walls are assembled into the positioning blind groove. The positioning part is pressed and positioned with the positioning blind groove, thereby ensuring the structural stability of the terminal and the insulating base. The first elastic arm, the second elastic arm, and the extension arm are placed inside the U-shaped blind hole and set outside the square through hole. When the plug is inserted into the square through hole, it elastically contacts the first and second elastic arms for information transmission. The setting of the extension arm ensures the stability of the entire terminal structure. Attached Figure Description
