[0002] An RF coaxial cable connector is required to connect the cable to the instrument. The RF coaxial connector is mainly composed of an inner conductor, an outer conductor, an insulating medium and a contact.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] refer to Figure 2-3 As shown, the utility model provides an RF coaxial cable connector, comprising: a cable body 1 and a connector body 7, wherein an installation space for plugging in the cable body 1 is formed in the connector body 7, and the cable body 1 is provided with a shielding layer 11, an insulator 12 and a battery core 9 in sequence from the outside to the inside, and a plurality of puncture needles 17 are provided in a circular array on the outside of the connector body 7, and one end of each of the plurality of puncture needles 17 can be movably plugged into the shielding layer 11.

[0021] Combination Figure 2-3 As shown, the connector body 7 is penetrated with a wiring hole 13 and a through hole 10 in sequence along the axial direction, the installation space is formed in the wiring hole 13, the battery core 9 is penetrated and arranged in the through hole 10, and the shielding layer 11 is inserted in the wiring hole 13.

[0022] As mentioned above, when using the cable body 1 and the connector body 7 provided by the utility model, one end of the cable body 1 is conveniently inserted into the connector body 7 through the wiring hole 13. At this time, the battery core 9 on the cable body 1 passes through the connector body 7 through the through hole 10, and multiple puncture needles 17 are simultaneously inserted into the wiring hole 13, so that the multiple puncture needles 17 are simultaneously sucked into the shielding layer 11, thereby realizing the connection between the connector body 7 and the shielding layer 11 and limiting the end of the cable body 1 on the connector body 7, thereby preventing the cable body 1 from being separated from the connector body 7.

[0023] Further, in order to facilitate the connection between the connector body 7 and the connector on the instrument, refer to Figure 1-2 As shown, the end of the connector body 7 away from the connecting portion 2 is also provided with a connecting screw sleeve 8 for connection, and the connecting screw sleeve 8 is sleeved on the connector body 7. When the battery core 9 on the connector body 7 is inserted into the plug, the connecting screw sleeve 8 is rotated, so that the connector body 7 can be detachably installed on the connector.

[0024] In the present utility model, combined with Figure 1-2 As shown, a connecting portion 2 is provided at one end of the connector body 7 of the present embodiment, and a plurality of mounting grooves 4 are provided in a circular array on the outer wall of the connecting portion 2, and a mounting hole 16 extending to the wiring hole 13 is provided in each mounting groove 4, and each puncture needle 17 is respectively inserted into the corresponding mounting hole 16, and a driving member for pressing the puncture needle 17 is installed in each of the plurality of mounting grooves 4.

[0025] Combination Figure 2-3 As shown, the driving member includes a movable rod 3, and a rotating shaft 14 is provided on the side of each mounting hole 16 facing away from the puncture needle 17. One end of the movable rod 3 is rotatably mounted on the rotating shaft 14, and one end of the puncture needle 17 is rotatably mounted on the movable rod 3. An external thread groove 5 is provided on the outside of the connecting part 2, and a screw ring 6 is screwed on the external thread groove 5 and is sleeved on the outside of multiple movable rods 3. The screw ring 6 is arranged on the side of the movable rod 3 close to the rotating shaft 14.

[0026] As mentioned above, when using the driving member provided by the utility model, the movable rod 3 in the driving member is rotatably installed in the installation groove 4 through the rotating shaft 14. When the movable rod 3 is rotated in the installation groove 4 toward the side of the puncture needle 17 through the rotating shaft 14, the puncture needle 17 is driven by the movable rod 3 to pierce the wiring hole 13, so that one end of the puncture needle 17 is pierced into the shielding layer 11, and then the shielding layer 11 is connected to the outer shell of the connector body 7. At the same time, multiple puncture needles 17 are used to prevent the cable body 1 from being separated from the connector body 7. When the screw ring 6 rotates, the screw ring 6 is moved toward one side of the movable rod 3 through the external thread groove 5, so that the multiple movable rods 3 are pressed into the installation groove 4, and then the movable rod 3 is pressed toward one side of the puncture needle 17 through the rotating shaft 14.
