Description

Technical Field

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

[0002] Radio frequency (RF) coaxial connectors are components that are attached to cables or installed on instruments. They serve as electrical connections or disconnections for transmission lines. With social development and progress, modern devices have become ubiquitous in people's lives.

[0003] In various electronic devices, control, communication, and detection systems often need to transmit many radio frequency (RF) signals simultaneously. Therefore, many RF transmission elements are required to interconnect the devices within themselves or between two or more electronic devices.

[0004] For example, the prior art Chinese patent publication number "CN208209196U" provides a switch-type RF coaxial connector, including a socket body. The socket body includes a first shell, a first contact, a second contact, and a third contact. The first, second, and third contacts are all disposed inside the first shell. By arranging the first, second, and third contacts inside the socket body, the second and third contacts are connected, and the third contact can move along the axial direction of the second contact. Under normal conditions, the third contact and the first contact are in contact and conducting, and the first frequency band is conducted in a normally open state.

[0005] When the device needs to access a second frequency band communication signal, it inserts the second frequency band terminal into the channel and connects it with the third contact, causing the third contact to separate from the first contact. This enables the two frequency bands to communicate independently without interference within the same connector, improving the space utilization of the connector, simplifying its structure, and making it compact.

[0006] Existing RF coaxial connectors, during use, do not have a secure enough connection between the connector and the plug. They are prone to relative rotation or sliding, which can cause the connection between the connector and the plug to become loose or even separate. This can lead to the disconnection of the RF coaxial connector, failing to provide a stable connection and easy separation between the connector and the plug.

[0007] Therefore, a switch-type RF coaxial connector is proposed. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies where the connection between the connector and the plug is not secure enough, and they are prone to relative rotation or sliding, leading to loosening or even separation of the connection between the connector and the plug, which in turn causes the RF coaxial connector to break. Therefore, this invention proposes a switch-type RF coaxial connector.

[0009] To achieve the above objectives, this utility model provides the following technical solution: Design a switchable RF coaxial connector, including a connector base and a connector. A connector ring is fixed to the front end of the connector base. The connector slides into the connector ring. The connector ring has inlet / outlet slots on both sides. A snap-fit ​​groove is formed at the inner end of the inlet / outlet slot. A snap-fit ​​mechanism is installed at the top of the snap-fit ​​groove, and a pop-out mechanism is installed at the inner end of the snap-fit ​​groove. The snap-fit ​​mechanism includes a snap-fit ​​post. An abutment surface is provided on the side of the snap-fit ​​post near the inlet / outlet slot. A first guide post is fixed to the top of the snap-fit ​​post. A telescopic groove is formed at the top of the snap-fit ​​groove, and a first guide hole is formed at the top of the telescopic groove. The snap-fit ​​post slides into the telescopic groove, and the first guide post slides... A first spring is sleeved on the surface of the first guide post, located between the snap-fit ​​post and the first guide post, passing through the first guide hole. A first limiting plate is fixed to the outer end of the first guide post, and a lifting ring is fixed to the outer end of the first limiting plate. The pop-out mechanism includes a spring plate. A second spring is connected to the inner end of the snap-fit ​​groove. The second spring is connected to the side of the spring plate. A support plate is fixed to the outer side of the snap-fit ​​groove. A second guide hole is opened on the surface of the support plate. A second guide post slides through the interior of the second guide hole. One end of the second guide post is fixedly connected to the side of the spring plate, and the other end is fixed to the second limiting plate.

[0010] Furthermore, a insertion groove is provided in the middle of the side of the connector, a cleaning sleeve is connected to the outside of the insertion groove, and a connecting core is fixed in the middle of the side of the connector. The connecting core passes through the cleaning sleeve and is inserted into the insertion groove.

[0011] Furthermore, a first rubber ring is bonded to the inner side of the connector, the first rubber ring being tightly inserted into the inner end of the connector ring, and a second rubber ring is bonded to the surface of the connector, the second rubber ring abutting against the outer end of the connector ring.

[0012] Furthermore, mounting posts are fixed on both sides of the connector and at positions between the first rubber ring and the second rubber ring. The mounting posts slide through the inlet / outlet groove and are inserted into the inside of the snap-fit ​​groove. One side of the mounting post abuts against the side of the snap-fit ​​post away from the abutting surface, and the other side of the mounting post abuts against the spring plate.

[0013] Furthermore, the rear end of the connector is connected to a first connecting line, and the rear end of the plug is connected to a second connecting line. Both the connector and the plug are cylindrical structures, the plug ring is an annular structure, the inlet / outlet groove and the snap-fit ​​groove are rectangular groove structures, and they are combined to form an L-shaped structure. The inlet / outlet groove is parallel to the axial direction of the plug ring, and the snap-fit ​​groove is perpendicular to the axial direction of the plug ring.

[0014] Furthermore, the snap-fit ​​post is a rectangular post structure, the abutting surface is an inclined surface structure, the telescopic groove is a rectangular groove structure, and the first limiting plate is located outside the plug ring.

[0015] Furthermore, the spring plate has a rectangular plate structure, with one end slidably inserted into the snap-fit ​​groove. The support plate and the spring plate are parallel to each other and fixed to the outside of the insertion ring.

[0016] Furthermore, the cleaning sleeve is made of rubber, and its inner diameter is smaller than that of the connecting core. The mounting post is a cylindrical structure and is perpendicular to the axis of the connector.

[0017] The switchable RF coaxial connector proposed in this utility model has the following advantages: 1. This utility model, by setting a snap-fit ​​mechanism and a pop-out mechanism inside the snap-fit ​​groove, allows the snap-fit ​​pin to slide into the snap-fit ​​groove, and the spring plate to be elastically installed inside the snap-fit ​​groove via the second spring and the second guide pin. Thus, when the connector and the connecting seat are plugged in and connected, the connector is inserted into the connector ring, and the mounting pin passes through the inlet / outlet groove. Twisting the connector causes the mounting pin to enter the snap-fit ​​groove and push against the abutment surface, pushing the snap-fit ​​pin upwards. This causes the snap-fit ​​pin and the first guide pin to move upwards along the first guide hole and the telescopic groove, compressing the first spring. Afterwards, the mounting pin continues to move into the snap-fit ​​groove and abuts against the spring plate until it disengages from the snap-fit ​​pin. Then, the first spring springs downwards, pushing the snap-fit ​​pin downwards and abutting against the snap-fit ​​groove. Inside the slot, one side of the mounting post is engaged and blocked. Simultaneously, the twisting of the connector is stopped and released. At the same time, the second spring extends and pushes the spring plate to move along the second guide post, engaging the other side of the mounting post. This keeps the mounting post stably installed inside the slot, thus maintaining a stable connection between the connector and the connector seat. When separating the connector and the connector seat, the locking post can be moved along the telescopic slot by the lifting ring, compressing the first spring. At the same time, the second spring extends and pushes the spring plate, causing the spring plate to move along the second guide post, pushing the mounting post to the connection between the slot and the inlet / outlet slot. This facilitates pulling the connector and the mounting post outward, thereby separating the connector and the connector seat.

[0018] 2. This utility model provides a first rubber ring on the surface of the connector and a second rubber ring on its inner side. At the same time, a cleaning sleeve is connected to the outer end of the connector groove. Thus, during the connection between the connector and the connector seat, the connector core passes through the cleaning sleeve and is inserted into the connector groove. The cleaning sleeve can clean the dust and impurities adhering to the surface of the connector core. Meanwhile, the connector is inserted into the connector ring, and the second rubber ring reduces the impact between the connector and the connector seat, maintaining a buffered contact installation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The diagram shows a switch-type RF coaxial connector, including a connector 1 and a plug 7. A plug ring 3 is fixed to the front end of the connector 1. The plug 7 is slidably inserted into the plug ring 3. The plug ring 3 has inlet and outlet grooves 9 on both sides. A snap-fit ​​groove 10 is opened at the inner end of the inlet and outlet grooves 9. A snap-fit ​​mechanism is installed at the top of the snap-fit ​​groove 10. A pop-out mechanism is installed at the inner end of the snap-fit ​​groove 10.

[0024] The locking mechanism includes a locking post 22. A contact surface 23 is provided on the side of the locking post 22 near the inlet / outlet groove 9. A first guide post 25 is fixed to the top of the locking post 22. A telescopic groove 18 is opened at the top of the locking groove 10. A first guide hole 27 is opened at the top of the telescopic groove 18. The locking post 22 is slidably inserted into the telescopic groove 18. The first guide post 25 slides through the first guide hole 27. A first spring 24 is sleeved on the surface of the first guide post 25 at the position between the locking post 22 and the first guide hole 27. A first limiting plate 16 is fixed to the outer end of the first guide post 25. A lifting ring 13 is fixed to the outer end of the first limiting plate 16.

[0025] The pop-out mechanism includes a spring plate 11. A second spring 26 is connected to the inner end of the snap-fit ​​groove 10. The second spring 26 is connected to the side of the spring plate 11. A support plate 12 is fixed to the outer side of the snap-fit ​​groove 10. A second guide hole 17 is opened on the surface of the support plate 12. A second guide post 5 slides through the interior of the second guide hole 17. One end of the second guide post 5 is fixedly connected to the side of the spring plate 11, and the other end is fixed to a second limiting plate 4.

[0026] Mounting posts 19 are fixed on both sides of the connector 7 and located between the first rubber ring 20 and the second rubber ring 6. The mounting posts 19 are cylindrical and perpendicular to the axial direction of the connector 7. The mounting posts 19 slide through the inlet / outlet groove 9 and are inserted into the inside of the snap-fit ​​groove 10. One side of the mounting posts 19 abuts against the side of the snap-fit ​​post 22 away from the abutment surface 23, and the other side of the mounting posts 19 abuts against the spring plate 11.

[0027] When the connector 7 is plugged into the connector 1, the connector 7 is inserted into the connector ring 3, and the mounting post 19 passes through the inlet / outlet groove 9. The connector 7 is then rotated so that the mounting post 19 enters the snap-fit ​​groove 10 and pushes against the abutment surface 23, causing the snap-fit ​​post 22 to move upward. This causes the snap-fit ​​post 22 and the first guide post 25 to move upward along the first guide hole 27 and the telescopic groove 18, compressing the first spring 24. Afterward, the mounting post 19 continues to move into the snap-fit ​​groove 10 and abuts against the push spring plate 11 until it snaps into place. After the posts 22 are separated, the first spring 24 springs downward, causing the snap-fit ​​post 22 to spring downward and abut against the inside of the snap-fit ​​groove 10, and snaps against one side of the mounting post 19. At the same time, the twisting of the plug 7 stops and is released. Simultaneously, the second spring 26 extends and pushes the spring plate 11 to move along the second guide post 5, and springs against the other side of the mounting post 19, thereby keeping the mounting post 19 stably installed inside the snap-fit ​​groove 10, and thus maintaining a stable plug-in installation connection between the plug 7 and the connecting seat 1.

[0028] The rear end of the connector 1 is connected to a first connecting line 2, and the rear end of the plug 7 is connected to a second connecting line 8. Both the connector 1 and the plug 7 are cylindrical structures, the plug ring 3 is an annular structure, the inlet / outlet groove 9 and the snap-fit ​​groove 10 are rectangular groove structures, and they are combined to form an L-shaped structure. The inlet / outlet groove 9 is parallel to the axis of the plug ring 3, and the snap-fit ​​groove 10 is perpendicular to the axis of the plug ring 3.

[0029] The snap-fit ​​post 22 is a rectangular post structure, the abutment surface 23 is an inclined surface structure, the telescopic groove 18 is a rectangular groove structure, and the first limiting plate 16 is located outside the plug ring 3.

[0030] The spring plate 11 has a rectangular plate structure, with one end slidably inserted into the snap-fit ​​groove 10. The support plate 12 is parallel to the spring plate 11 and is fixed to the outside of the insertion ring 3.

[0031] Thus, when separating the connector 7 from the connecting seat 1, the locking post 22 can be moved along the telescopic groove 18 by the lifting ring 13, and the first spring 24 can be compressed. At the same time, the second spring 26 extends and pushes the spring plate 11, so that the spring plate 11 moves along the second guide post 5, pushing the mounting post 19 to the connection between the locking groove 10 and the inlet / outlet groove 9, thereby facilitating the outward pulling of the connector 7 and the mounting post 19, and thus separating the connector 7 from the connecting seat 1.

[0032] Example 2

[0033] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The diagram shows a switch-type RF coaxial connector, including a connector 1 and a plug 7. A plug ring 3 is fixed to the front end of the connector 1. The plug 7 is slidably inserted into the plug ring 3. The plug ring 3 has inlet and outlet grooves 9 on both sides. A snap-fit ​​groove 10 is opened at the inner end of the inlet and outlet grooves 9. A snap-fit ​​mechanism is installed at the top of the snap-fit ​​groove 10. A pop-out mechanism is installed at the inner end of the snap-fit ​​groove 10.

[0034] The connector 1 has a socket 14 in the middle of its side, and a cleaning sleeve 15 is connected to the outside of the socket 14. The connector 7 has a connecting core 21 fixed in the middle of its side, and the connecting core 21 passes through the cleaning sleeve 15 and is inserted into the socket 14.

[0035] A first rubber ring 20 is bonded to the inner side of the connector 7. The first rubber ring 20 is tightly inserted into the inner end of the connector ring 3. A second rubber ring 6 is bonded to the surface of the connector 7. The second rubber ring 6 abuts against the outer end of the connector ring 3.

[0036] A first rubber ring 6 is provided on the surface of the connector 7, and a second rubber ring 20 is provided on its inner side. At the same time, a cleaning sleeve 15 is connected to the outer end of the insertion groove 14. Thus, during the insertion and connection between the connector 7 and the connector 1, the connecting core 21 passes through the cleaning sleeve 15 and is inserted into the insertion groove 14. The cleaning sleeve 15 can clean the dust and impurities adhering to the surface of the connecting core 21. At the same time, the connector 7 is inserted into the insertion ring 3, and the second rubber ring 20 reduces the impact between the connector 7 and the connector 1, maintaining a buffered contact installation.

[0037] The cleaning sleeve 15 is made of rubber, and its inner diameter is smaller than that of the connecting core 21.

[0038] Working method: A snap-fit ​​mechanism and a pop-out mechanism are set inside the snap-fit ​​groove 10. Therefore, the snap-fit ​​post 22 slides into the snap-fit ​​groove 10, and the spring plate 11 is elastically installed inside the snap-fit ​​groove 10 by the second spring 26 and the second guide post 5.

[0039] Thus, when the connector 7 and the connector 1 are connected by insertion, the connector 7 is inserted into the connector ring 3, and the mounting post 19 passes through the inlet / outlet groove 9. Twisting the connector 7 causes the mounting post 19 to enter the snap-fit ​​groove 10 and push against the abutment surface 23, pushing the snap-fit ​​post 22 upwards. This causes the snap-fit ​​post 22 and the first guide post 25 to move upwards along the first guide hole 27 and the telescopic groove 18, compressing the first spring 24. Afterwards, the mounting post 19 continues to move into the snap-fit ​​groove 10 and abuts against the pushing spring plate 11 until it engages with the snap-fit ​​plate. After the connector 22 disengages, the first spring 24 springs downward, causing the locking connector 22 to spring downward and abut against the inside of the locking groove 10, and locking and blocking one side of the mounting post 19. At the same time, the screw-in connector 7 is stopped and released. Simultaneously, the second spring 26 extends and pushes the spring plate 11 to move along the second guide post 5, springing and abutting against the other side of the mounting post 19, thereby keeping the mounting post 19 stably installed inside the locking groove 10, and thus maintaining a stable plug-in connection between the connector 7 and the connector 1.

[0040] Thus, when separating the connector 7 from the connecting seat 1, the locking post 22 can be moved along the telescopic groove 18 by the lifting ring 13, and the first spring 24 can be compressed. At the same time, the second spring 26 extends and pushes the spring plate 11, so that the spring plate 11 moves along the second guide post 5, pushing the mounting post 19 to the connection between the locking groove 10 and the inlet / outlet groove 9, thereby facilitating the outward pulling of the connector 7 and the mounting post 19, and thus separating the connector 7 from the connecting seat 1.

[0041] A first rubber ring 6 is provided on the surface of the connector 7, and a second rubber ring 20 is provided on its inner side. Simultaneously, a cleaning sleeve 15 is connected to the outer end of the insertion groove 14. Thus, during the insertion and connection between the connector 7 and the connector 1, the connecting core 21 passes through the cleaning sleeve 15 and is inserted into the insertion groove 14. The cleaning sleeve 15 can clean away dust and impurities adhering to the surface of the connecting core 21. At the same time, the connector 7 is inserted into the insertion ring 3, and the second rubber ring 20 reduces the impact between the connector 7 and the connector 1, maintaining a buffered contact installation. The above description is only a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
