Description

Technical Field

[0001] This utility model relates to the field of connector technology and equipment, specifically a radio frequency connector. Background Technology

[0002] Previous RF connectors had relatively straight mating parts or small contact surfaces, which easily caused poor contact. Furthermore, when inserting the RF connector, it was easy for it to become misaligned. Since the internal parts were not visible, this caused misalignment. The two ends of the RF connector needed to be connected through other components, which was quite cumbersome.

[0003] Document CN201821951387 discloses an RF connector assembly and a microwave module, including a multilayer board and at least one RF connector disposed in the multilayer board. The multilayer board has at least one blind via. The RF connector includes an inner conductor and an outer conductor, which are disposed within the at least one blind via, with the inner conductor located inside the outer conductor. The outer conductor, inner conductor, and blind via of the RF connector are coaxially arranged. This structure results in a small contact area with an external plug during use, making it prone to issues such as missed connections.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses an RF connector that can improve the insertion speed between the external plug and the connector, preventing misalignment during insertion and thus improving insertion accuracy.

[0006] The technical solution of this utility model is as follows: an RF connector, including a head and a tail. The head is connected to the tail by a locking ring and a threaded connection. The head is provided with a plug part, which is in the shape of an inward inverted U. A guide tube is provided at the top of the plug part. A rubber pad is provided above the internal thread of the locking ring provided on the periphery of the head. The rubber pad abuts against the upper end face of the tail.

[0007] By adopting the above technical solution, when the head and tail are connected, the connection between the two is tighter and more secure because the head is pressed against the upper surface of the tail by the rubber pad. The shape of the guide tube and the plug can improve the insertion of external devices.

[0008] Preferably, the insertion part is symmetrically arranged with the center of the receiving plate as the symmetrical point. The insertion part includes a vertical part, a U-shaped part and a connecting part. The bottom of the vertical part is vertically connected to the receiving plate, and the receiving plate is located on one side of the head near the end.

[0009] By adopting the above technical solution, the contact area when external devices are plugged in is increased, enabling rapid plugging and unplugging.

[0010] Preferably, one end of the U-shaped portion is connected to the vertical portion, and the other end is connected to the connecting portion. The U-shaped portion bends outward, and the connecting portion and the vertical portion are not parallel. The end of the vertical portion has a tendency to move towards the middle.

[0011] By adopting the above technical solution, the end of the vertical part is oriented towards the middle, which allows for quick insertion of external plugs. The external plugs can quickly touch the insertion part, thus increasing the insertion speed.

[0012] Preferably, the top of the head has a through hole for inserting external components, and a guide tube is located around the through hole, with the inner diameter of the guide tube being the same as the inner diameter of the through hole.

[0013] By adopting the above technical solution, the guide tube can improve the insertion accuracy of the external plug towards the connector, and directly and accurately insert it into the connector through the through hole.

[0014] Preferably, a locking ring is provided on the side of the head near the tail, the locking ring and the head are integrally formed, and the locking ring is fixed by connecting and fixing the internal thread and the external thread of the tail.

[0015] By adopting the above technical solution, the connection strength between the locking ring and the head is improved, so the locking ring and the tail are directly connected without the need for other components, which is more convenient and faster.

[0016] Preferably, a rubber pad is provided on one side of the internal thread on the inner side of the locking ring, and the rubber pad abuts against the upper end face of the tail.

[0017] By adopting the above technical solution, the rubber pad can improve the connection tightness between the head and tail, making the connection between the head and tail more secure.

[0018] Preferably, the bottom of the receiving tray is connected to the inner conductor via a guide rod, and a groove is provided at the bottom of the tail.

[0019] The advantages of this utility model are as follows: 1. By setting the plug part to an inverted U-shape and the connecting part to be inclined inward, the plug can quickly contact the plug part when it is inserted into it, and it can be adapted to different plug models. If the diameter of the plug is small, the inward inclination of the plug part can be adapted to plugs of different diameters.

[0020] 2. This utility model provides a guide tube below the through hole. When the plug is inserted, the guide tube prevents the plug from tilting and allows it to be directly inserted into the connector, thus improving the connection speed between the external plug and the connector.

[0021] 3. This utility model provides a rubber pad between the head and tail to achieve a tight connection between the head and tail, making the connection between the head and tail tighter and more secure. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1-4 As shown, the RF connector includes a head part 1 and a tail part 10. The head part 1 is connected to the tail part 10 by a locking ring 5 and a threaded connection. The head part 1 has a plug part 4 inside, which is generally in an inward U-shape. The top of the plug part 4 is provided with a guide tube 3. A rubber pad 6 is provided above the internal thread of the locking ring 5 on the periphery of the head part 1. The rubber pad 6 abuts against the upper end face of the tail part 10. When the head part 1 and the tail part 10 are connected, the head part 1 is pressed against the upper end face of the tail part 10 by the rubber pad 6, so the connection between the two is tighter and more secure. The shape of the guide tube 3 and the plug part can improve the insertion of external devices.

[0029] The insertion part 4 is symmetrically arranged with the center of the receiving plate 7 as the symmetrical point. The insertion part 4 includes a vertical part 401, a U-shaped part 402 and a connecting part 403. The bottom of the vertical part 401 is vertically connected to the receiving plate 7. The receiving plate 7 is located on one side of the head near the end, which increases the contact area when external devices are inserted and realizes quick insertion.

[0030] One end of the U-shaped part 402 is connected to the vertical part 401, and the other end is connected to the connecting part 403. The U-shaped part 402 is bent outward. The connecting part 403 and the vertical part 401 are not parallel. The end of the vertical part 401 has a tendency to move towards the middle. In this way, the plug inserted from the outside can be quickly plugged in. The external plug can quickly touch the plugging part 4, which improves the plugging speed.

[0031] The top of the head has a through hole 2 for inserting external components. The guide tube 3 is located around the through hole 2. The inner diameter of the guide tube 3 is the same as the inner diameter of the through hole 2. The guide tube 3 can improve the insertion accuracy of the external plug towards the plug-in part 4. The plug is inserted directly and accurately into the plug-in part 4 through the through hole 2.

[0032] A locking ring 5 is provided on the side of the head part 1 near the tail part 10. The locking ring 5 and the head part 1 are integrally formed. The locking ring 5 is fixed by connecting the internal thread and the external thread of the tail part 10. The locking ring 5 improves the connection strength between the head part 1 and the tail part 1. Therefore, the locking ring 5 and the tail part 10 are directly connected without the need for other parts, which is more convenient and faster.

[0033] A rubber pad 6 is provided on one side of the internal thread on the inner side of the locking ring 5. The rubber pad 6 is in contact with the upper end face of the tail 10. The rubber pad 6 can improve the connection tightness between the head 1 and the tail 10, making the connection between the head 1 and the tail 10 more secure.

[0034] The bottom of the receiving plate 7 is connected to the inner conductor 9 via the guide rod 8, and the bottom of the tail 10 is provided with a groove.

[0035] When the external plug is inserted into the head 1, the plug can be quickly aligned with the middle of the insertion part 4 because the guide tube 3 is provided below the through hole of the head 1. The connecting part 403 of the insertion part 4 is inclined inward. When the plug enters, even if the diameter of the plug is smaller than the distance between the insertion parts, it can still quickly contact the connecting part 403 to achieve connection at the fastest speed. The rubber pad 6 between the head 1 and the tail 10 can achieve tight contact between the two.
