Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a simplified radio frequency coaxial connector. Background Technology

[0002] Radio frequency (RF) coaxial connectors are essential components widely used in communications, electronic equipment, and other fields. Traditional RF coaxial connectors typically employ a direct-insertion connection, where the hole end of the head connector directly mates with the pin end of the head connector. This direct mating results in insufficient connection stability and a tendency to detach under external forces. To address this, a threaded sleeve is used at one end of the housing to create a threaded connection between the housing and the mating connector, while an internally threaded tail connector is located on the inner wall of the other end of the housing to secure the cable. This structure results in a relatively large radial dimension of the housing, making it unsuitable for applications with limited space. Furthermore, the connector's insulating shell and the housing are mating; even slight dimensional deviations can prevent a tight seal, affecting the connector's reliability. Therefore, it is necessary to provide a simplified RF coaxial connector to solve, or at least partially solve, the aforementioned problems. Utility Model Content

[0003] This utility model provides a simplified radio frequency coaxial connector with an optimized structure. The outer shell is equipped with a mating snap and a crimping section, which can reliably connect while reducing the radial dimension of the outer shell. The inner shell is provided with barbs to achieve a reliable connection between the insulating shell and the outer shell.

[0004] This utility model provides a simplified radio frequency coaxial connector, including pins, an insulating shell, and an outer shell. The pins are disposed in the insulating shell, and the insulating shell is disposed in the outer shell. The outer shell includes a first connecting section, a first mounting section, and a crimping section arranged coaxially in sequence. The insulating shell includes a second connecting section, a second mounting section, and a third connecting section arranged coaxially in sequence. The pins include a needle tip section and a soldering section arranged coaxially in sequence. The soldering section is correspondingly inserted into the second mounting section. The third connecting section and the second mounting section are inserted and fixed inside the first mounting section. The inner wall of the first mounting section is provided with barbs to prevent the insulating shell from detaching from the outer shell. The second connecting section is located inside the first connecting section. The end of the needle tip section away from the soldering section forms a tapered head. The end of the soldering section away from the needle tip section is provided with a mounting boss for positioning. The outer wall of the first connecting section is provided with multiple mating snaps, which are connected by a rotating groove arranged circumferentially along the first connecting section.

[0005] Preferably, the pairing buckles are two that are equally spaced along the outer circumference of the first connecting segment, and the rotating groove is an arc-shaped groove.

[0006] Preferably, the end of the welding section away from the needle section is provided with a core wire connection hole, and the side wall of the core wire connection hole is provided with a through welding hole. When connecting the cable, the core wire of the cable is inserted into the core wire connection hole, and the core wire is welded to the side wall of the core wire connection hole through the welding hole.

[0007] Preferably, the inner diameters of the first connecting section, the first mounting section, and the crimping section decrease sequentially; the outer diameters of the third connecting section and the second mounting section are the same and match the inner diameter of the first mounting section; and the crimping section defines the depth to which the insulating shell is inserted into the outer shell.

[0008] Preferably, the device further includes an insulating connecting washer disposed within the third connecting segment. The outer diameter of the insulating connecting washer matches the inner diameter of the third connecting segment, and the inner diameter of the third connecting segment is larger than the inner diameter of the second mounting segment. When the insulating connecting washer is disposed within the third connecting segment, it abuts against the end of the second mounting segment.

[0009] Preferably, the length of the insulating connecting washer is greater than the length of the third connecting segment, the inner diameter of the third connecting segment is the same as the inner diameter of the crimping segment, and the insulating connecting washer extends into the crimping segment when it is disposed in the third connecting segment.

[0010] Preferably, the insulating connecting washer has a core wire through hole at the end near the second mounting section, and a cable through hole at the end away from the second mounting section. The core wire through hole and the cable through hole are coaxially connected, and the diameter of the cable through hole is larger than the diameter of the core wire through hole. When the core wire of the cable passes through the insulating connecting washer to connect to the pin, the core wire passes through the cable through hole and exits from the core wire through hole, and the end of the cable connecting the core wire is located in the cable through hole.

[0011] Preferably, the diameter of the cable is slightly smaller than the inner diameter of the crimping section, and the cable is locked by deforming the crimping section through pressing.

[0012] Preferably, the inner wall of the end where the second mounting section connects to the third connecting section is provided with a groove matching the mounting boss, and when the pin is installed in the insulating shell, the mounting boss is disposed in the groove.

[0013] Preferably, the pin is made of beryllium copper, the insulating shell is made of plastic, and the outer shell is made of metal.

[0014] Compared with the prior art, the technical solution of this utility model has beneficial effects.

[0015] For example, a simplified RF coaxial connector includes pins, an insulating shell, and a housing. The pins are housed within the insulating shell, which in turn is housed within the housing. The housing includes a first connecting section, a first mounting section, and a crimping section arranged coaxially in sequence. The insulating shell also includes a second connecting section, a second mounting section, and a third connecting section arranged coaxially in sequence. The pins include a tip section and a soldering section arranged coaxially in sequence. The soldering section is inserted into the second mounting section. The third connecting section and the second mounting section are inserted into and fixed within the first mounting section. The inner wall of the first mounting section has barbs that prevent the insulating shell from detaching from the housing, thus achieving bonding between the insulating shell and the housing. Reliable connection; the second connecting section is located inside the first connecting section; the end of the needle section away from the welding section forms a tapered head; the end of the welding section away from the needle section is provided with a mounting boss for positioning, and the positioning and installation of the needle is achieved through the mounting boss; the outer wall of the first connecting section is provided with multiple mating buckles, and the multiple mating buckles are connected by a rotating groove provided along the circumference of the first connecting section; the mating buckles and rotating grooves are used to connect with other connectors, ensuring reliable connection while simplifying the structure and reducing the radial dimension; fewer component parts are required, simplifying the time and steps required for assembly, and improving assembly efficiency and fault tolerance.

[0016] For example, an insulating connecting washer is set inside the third connecting section. The outer diameter of the insulating connecting washer matches the inner diameter of the third connecting section. The inner diameter of the third connecting section is larger than the inner diameter of the second mounting section. When the insulating connecting washer is set in the third connecting section, it abuts against the end of the second mounting section, which strengthens the insulation between the pin and the housing. At the same time, it plays a role in limiting and fixing the soldered pin, making it more stable when paired and pulled out.

[0017] For example, if the diameter of the cable is slightly smaller than the inner diameter of the crimping section, the cable can be locked in place by deforming the crimping section, without the need for additional accessories. Attached Figure Description
