Embodiment 1

[0030] This embodiment provides a circuit board connector, which is used in a transceiver to connect an AAS module as a radio frequency connection between circuit boards, such as figure 2 As shown, the circuit board connector includes: outer conductors 33, 34, inner conductors 35 and connecting parts 36, 37;

[0031] Wherein, the outer conductor is a metal cylindrical structure, and the inner conductor 35 is a regular and uniform columnar metal body with a smooth surface, which ensures that the inner conductor has better conductive continuity. The inner conductor 35 is independent of the outer conductor and is arranged in the outer conductor. The inner conductor 35 and the outer conductor 33, 34 are filled with an insulating medium (such as air), so that the inner and outer conductors 35, 33, and 34 are separated by an insulating medium (air), which ensures that the surface current density of the inner conductor 35 is low, and the inner conductor 35 has a low surface current d...

Embodiment 2

[0039] Such as image 3 As shown, the structure of the circuit board connector provided in this embodiment is basically the same as that provided in Embodiment 1, and the lower end of the inner conductor 45 of the connector still adopts a deformable conductor (such as: conductor glue, reed, spring, etc. ) as the second connecting part 47 is movably connected with the lower circuit board 42 to realize the electrical connection between the lower end of the inner conductor 45 and the surface layer metal disc 421 of the lower circuit board 42 . The difference is that the upper end of the inner conductor 45 in the connector is provided with an internal thread, which is fixedly connected with the upper circuit board 41 through the internal thread and the screw as the first connecting part 46, that is, the screw passes through the upper circuit board 41 and is screwed into the inner In the internal thread on the upper end of the conductor 45 , the upper end of the inner conductor 45 ...

Embodiment 3

[0043] Such as Figure 4 As shown, the present embodiment provides a circuit board connector, the structure of which is basically the same as that of the connector provided in Embodiment 1, and the upper end of the inner conductor 55 of the connector still adopts a deformable conductor (such as : Conductor glue, reed, spring, etc.) as the first connecting part 56 and the upper circuit board 51 movably connected, realize that the upper end of the inner conductor 55 is electrically connected with the surface layer metal disc 511 of the upper circuit board 51; the difference is that the connector The lower end of the inner conductor 55 is provided with an external thread, and through the outer thread, the lower end of the inner conductor 55 is matched with the nut 57 arranged on the lower circuit board 52 as the second connecting part 57, and is fixedly connected with the lower circuit board 52, so that the lower end of the inner conductor 55 is connected to the lower end of the i...

Abstract

The invention provides a circuit board connector and communication equipment, belonging to the technical field of communication. The circuit board connector comprises an outer conductor, an inner conductor and a connecting piece, wherein the outer conductor is in a metal cylindrical structure; the inner conductor is a cylindrical metal body, and is independent of the outer conductor and arranged in the outer conductor; an insulating medium is filled between the inner conductor and the outer conductor; and two ends of the inner conductor are connected with the connecting piece of the circuit board respectively. The connector has simple structure, no complicated mechanical structure and low material cost; and the outer conductor can be shared with a structure piece, and the structure piece is manufactured by a die sinking method without increasing additional cost.

Description

technical field [0001] The invention relates to the communication field, in particular to a circuit board connector and communication equipment. Background technique [0002] In the communication transceiver equipment, the connector between the circuit boards is used to connect two PCB boards to ensure that the radio frequency connection and mechanical tolerance can be realized between the two PCB boards. Since the transceiver is gradually evolving to a low-power multi-channel AAS (Active Antenna System, Active Antenna System), that is, the transceiver and the antenna are integrated and connected through the connector inside the module to replace the original transceiver and antenna. feeder connections between them. In this process, the duplexer module and the antenna module have undergone obvious changes. The low power makes it no longer necessary to use a cavity duplexer for the duplexer, and instead use a smaller, lower-priced dielectric duplexer. The duplexer is no lon...
