[0002] The SMA connector is an ultra-small coaxial cable connector, named after the Sub-Miniature A connector. This connector is widely used in the radio frequency (RF) and microwave industries, primarily for transmitting RF signals at frequencies up to 18 GHz or higher. SMA connectors are suitable for microwave applications up to 26.5 GHz, including telecommunications, networking, wireless communications, and testing and measuring instruments.

[0003] In the existing technology, when the SMA connector is connected to the cable, the cable is easily pulled loose by external force, which affects the stability of the connection between the SMA connector and the cable. Summary of the Invention

[0011] A locking plate is fixedly connected to the inner wall of the locking assembly.

[0012] Furthermore, the SMA connector assembly includes a connector end, a soldering base, and a signal probe. The connector end is fixedly connected to the soldering base, and a signal probe penetrating the soldering base is installed inside the connector end. A pin is installed on the right side of the soldering base.

[0013] Furthermore, the cable assembly includes a cable and a fixing sleeve. The right end of the cable is fixedly sleeved with the fixing sleeve. A slot is formed on the top surface of the fixing sleeve, and a fixing groove formed inside the fixing sleeve is connected to the slot.

[0016] Furthermore, the locking assembly includes a placement plate, a limiting plate, and a fixing head. The placement plate is engaged in the placement groove. A locking plate is fixedly connected to the bottom side of the placement plate. A limiting plate is fixedly connected to the left side of the placement plate. The limiting plate is engaged in the groove. A fixing head is fixedly connected to the bottom left end of the limiting plate. The fixing head is used to engage with the fixing groove.

The placement plate causes the bottom locking plate to disengage from the locking groove, and at the same time, the limiting plate moves outwards, ensuring that the fixed cylinder and the connecting end are threadedly connected. After the fixed cylinder and the connecting end are stably connected, the rotating ring causes the adjusting limiting plate to be located on one side of the limiting groove. The adjusting positioning plate disengages from the positioning groove, and under the action of the elastic spring, the limiting plate engages in the limiting groove. At the same time, the limiting plate causes the fixed head of the fixed connection to engage with the fixing groove opened on the surface of the fixed cylinder, further improving the anti-loosening fixing effect of the limiting plate on the fixed cylinder, strengthening the connection stability between the cable and the SMA connector, ensuring stable signal transmission, and reducing the external force on the connection between the cable and the SMA connector.

[0043] SMA connector assembly 1;

[0044] Cable assembly 2;

[0045] Rotation mechanism 3, which is mounted on the surface of SMA connector assembly 1;

[0046] An elastic clamping component 4 is mounted on the surface of the SMA connector assembly 1. A locking component 5 is mounted on the top side of the elastic clamping component 4, and a locking component 5 is mounted on the surface of the elastic clamping component 4.

[0047] Locking plate 6 is fixedly connected to the inner wall of locking assembly 5.

[0048] Improve the anti-detachment fixing effect of the limit plate 51 on the fixed cylinder 22, strengthen the connection stability between the cable and the SMA connector, ensure stable signal transmission, and reduce the impact of external forces on the connection between the cable and the SMA connector.

[0049] The SMA connector assembly 1 includes a connector 14, a soldering base 11, and a signal probe 13. The connector 14 is fixedly connected to the soldering base 11.

[0050] Pin 12 is designed to facilitate connection to the PCB board.

[0051] The cable assembly 2 includes a cable 21 and a fixing cylinder 22. The right end of the cable 21 is fixedly sleeved with the fixing cylinder 22. The top surface of the fixing cylinder 22 is provided with a slot 23, and a fixing groove 24 is connected in the slot 23.

[0052] The inner wall of the fixed cylinder 22 is threadedly connected to the surface of the connecting end 14.

[0053] The rotating mechanism 3 includes a fixed ring 31, a rotating ring 32, and a limiting ring 35. The fixed ring 31 is fixedly sleeved on the surface of the connecting end 14. The rotating ring 32 is rotatably sleeved on the top surface of the fixed ring 31.

The rotating ring 32 is rotatably fitted with the side surface of the limiting ring 35. A placement groove 34 is opened on the top surface of the rotating ring 32.

[0054] The rotating ring 32 is limited by the limiting ring 35, which effectively ensures the stable rotation of the rotating ring 32, and at the same time facilitates the rotation of the rotating ring along the fixed ring 31, making it convenient to adjust the rotating ring 32.

[0055] The locking assembly 5 includes a placement plate 52, a limiting plate 51, and a fixing head 53. The placement plate 52 is engaged in the placement groove 34.

The fixing head 53 is used to engage with the fixing groove 24.

[0056] During assembly, after the fixed cylinder 22 is threadedly connected to the connecting end 14, the elastic clamping component 4 causes the placement plate 52 to move downward. The placement plate 52 drives the fixed connection limiting plate 51 to engage in the slot 23 opened on the surface of the fixed cylinder 22, effectively realizing the anti-rotation limiting of the fixed cylinder 22 by the limiting plate 51.

The pull rod 45 is fixedly installed on the top side surface of the placement plate 52.

[0058] When connecting cable 21 to SMA connector, rotating cylinder 46 drives positioning plate 47 to rotate, positioning plate 47 then presses against top plate 43, and pull rod 45 drives fixed connection placement plate 52 to move up along support column 41. Finally, the bottom end of positioning plate 47 engages in positioning groove 44 on top side of top plate 43, placement plate 52 drives bottom locking plate 6 to disengage from locking groove 33, and limit plate 51 moves outward to ensure threaded connection between fixed cylinder 22 and connection end 14.

Under the action of elastic spring 42, limit plate 51 engages in limit groove, and limit plate 51 drives fixed connection fixing head 53 to engage with fixing groove 24 opened on surface of fixed cylinder 22, further improving the anti-detachment fixing effect of limit plate 51 on fixed cylinder 22.
