[0024] The front side of the connector body 1 is also provided with a wiring core groove 5 , in which a gear plate 6 is rotatably provided. The gear plate 6 is provided with a plurality of inner cores 7 with different diameters, and the inner cores 7 are connected to the cable connection terminal 3 .

[0025] Please refer to Figure 5, the traditional feeding connector usually has a single core, and the size of the core cannot be changed. In this embodiment, the inner core 7 of the feeding connector is changed to a rotatable and adjustable multi-selective inner core 7, and the inner core 7 of different diameters is selected by rotating the gear plate 6, thereby increasing the adaptability of the connector to different antennas. A thicker antenna can select an inner core 7 with a small diameter, while a thinner antenna sample can select an inner core 7 with a large diameter.

[0026] Specifically, a gear plate 6 is provided in the wiring core slot 5, and a plurality of inner cores 7 are provided on the gear plate 6, and each inner core 7 is a cylindrical conductor with different diameters, which is used to connect the antenna radiation patch. When the gear plate 6 is rotated, the inner core 7 rotates with the gear plate 6 to the center position of the connector body 1, and can contact the antenna on the loading antenna clamping slot 2. By controlling the selection of the inner core 7 with the gear plate 6, the size of the inner core 7 with a certain impedance value is required, and the gear is rotated to adjust the corresponding inner core 7 to the center position to achieve connection with the antenna radiation patch. The other end of the inner core 7 is connected to the cable connection terminal 3, and the cable connection terminal 3 is connected to the cable through the external thread 4, thereby realizing the transmission and testing of the antenna signal.

[0027] Preferably, the gear plate 6 has a rotation center, and the center of the inner core 7 and the center of the connector body 1 are both on the circumference of the same outer limiting circle, and the center of the outer limiting circle coincides with the rotation center. Through the above structural design, the centers of multiple inner cores 7 are all on the circumference of the same outer limiting circle, and the center of the outer limiting circle coincides with the rotation center, so that when the inner core 7 rotates, its center position can be maintained on the same outer limiting circle. At the same time, the center of the connector body 1 is also on the circumference of the outer limiting circle, and when the inner core 7 rotates, it can accurately rotate to the center position of the connector body so as to better contact the film antenna.

[0028] Preferably, the side of the connector body 1 is provided with a slot 101 that matches the gear plate 6, and part of the gear plate 6 can extend from the slot 101. In this embodiment, the slot 101 is provided on the side of the connector body, and the gear plate 6 can be directly operated. The gear plate 6 can be manually driven to realize the switching of the inner core 7, which is convenient and quick to use.

[0029] Preferably, a ratchet mechanism is provided in the wiring core slot 5, and the ratchet mechanism is connected to the gear plate 6 to achieve unidirectional pushing of the gear plate 6. In this embodiment, by providing a ratchet mechanism, the gear plate 6 can achieve unidirectional pushing, so as to switch the size of the inner core 7 in sequence, which is convenient for blind operation. In addition, the pawl on the ratchet mechanism keeps in contact with the gear plate 6, which helps to stabilize the gear plate 6, reduce the self-rotation of the gear plate 6, and improve the stability of contact with the antenna.

[0030] Preferably, the wiring core groove 5 includes a first groove, a second groove and a third groove, wherein the first groove is used to accommodate a plurality of inner cores 7, the second groove is used to accommodate the gear plate 6, and the second groove is connected to the slot 101; the third groove is used to install the cable connection terminal. In this embodiment, the inner core 7 rotates in the first groove, the gear plate 6 rotates in the second groove, and the third groove is used to achieve the connection between the inner core 7 and the cable connection terminal.

[0031] Preferably, a spring sheet is provided on the cable connection terminal, and a contact matching the spring sheet is provided at one inner end of the inner core 7, and when the inner core 7 rotates to the position of the spring sheet, the contact contacts the spring sheet. By providing a spring sheet to connect the inner core 7, the installation structure of the inner core 7 is simpler, no wiring is required, and the internal space occupation is reduced.

[0032] Preferably, a connecting wire is provided at one end of the inner side of the inner core 7, and is connected to the cable connection terminal 3 through the connecting wire. A first limit block is provided on the inner side of the gear disc 6, and a second limit block cooperating with the first limit block is provided in the wiring core groove 5. In this embodiment, wiring can be used to ensure a stable connection between the inner core 7 and the cable connection terminal. In order to avoid the breakage of the connecting wire, the first limit block is provided on the gear disc 6, and the second limit block is provided in the wiring core groove 5. When one side of the first limit block contacts one side of the second limit block, the gear disc 6 cannot continue to rotate; when the gear disc 6 rotates in the opposite direction, when the other side of the first limit block contacts the other side of the second limit block, the gear disc 6 cannot continue to rotate. Through the above-mentioned structural design, the rotation limit of the gear disc 6 is realized, so that the probability of damage to the connecting wire is reduced in the case of wired connection.

[0033] Preferably, it also includes a spring clamping mechanism arranged in the wiring core groove 5, the spring clamping mechanism includes a telescopic spring, a clamping plate and an anti-slip plate, a clamping slot is provided on the side wall of the wiring core groove 5, the telescopic spring and the clamping plate are arranged in the clamping slot, one end of the telescopic spring is abutted against the clamping slot, and the other end is connected to the clamping plate, the clamping plate can be slid out in the clamping slot, and the anti-slip plate is arranged at the opening of the clamping slot to prevent the clamping plate from escaping from the clamping slot; the two sides of the clamping plate are guide slopes, and the middle part is an arc-shaped inner groove.

[0034] Through the above structural design, the two sides of the card plate are guide slopes, which facilitate the inner core 7 to squeeze the card plate along the guide slopes when passing through, so that the card plate is retracted toward the bottom of the card slot. When the inner core 7 reaches the arc-shaped inner groove, the card plate clamps the inner core 7, so that the inner core 7 remains stationary so as to maintain a stable connection with the film antenna. When it is necessary to continue rotating, the gear plate 6 is rotated, and the inner core 7 leaves the arc-shaped inner groove. The guide slopes on both sides facilitate the inner core 7 to enter the arc-shaped inner groove from both sides.

[0035] Compared with the prior art, the utility model has the following beneficial effects: the utility model changes the fixed core wire in the traditional feed connector into a rotatably adjustable multi-selective inner core structure, and controls the selection of the inner core through a gear plate to increase the adaptability between the feed connector and antennas of different thicknesses, greatly reducing the difficulty of designing the antenna feed connector and reducing the production cost of the feed connector. The connector of the utility model is not only suitable for thin film antennas, but also meets the requirements of conventional PCB antennas or antennas made of other materials with larger thicknesses, and has wide applicability.
