Description

Technical Field

[0001] The present application belongs to the field of coaxial cable connectors, and more specifically, relates to an elastic connector of a radio frequency coaxial connector and a connector including the elastic connector. Background Art

[0002] RF coaxial connectors (RF connectors), components that electrically connect or disconnect transmission lines, are mechatronic products. Other connectors with adjustable connection torques are more complex to adjust.

[0003] The installation of RF coaxial connectors currently on the market requires the use of a torque wrench to apply a large torque in order to provide a bonding force between the outer conductor of the RF coaxial connector and the cable, thereby ensuring the reliability of the connection. The front shell and the rear shell are usually reliably connected by threaded engagement. In order to allow the torque of the torque wrench to regulate the size of the bonding force without damaging the elastic parts in the rear shell, the front shell and the rear shell cannot be completely tightened and abutted during actual installation. A certain gap must be reserved between the two. However, the size of this gap depends entirely on human experience, and because the elastic parts connecting the outer conductor are in hard contact with the front shell and the rear shell in the axial direction, after multiple installations, the elastic parts will deform, thereby affecting their service life and, in turn, the connection reliability of the RF coaxial connector. Utility Model Content

[0004] In response to the defects of the existing technology or the need for improvement, the present application provides an elastic connector of an RF coaxial connector and a connector including the same, aiming to solve the problem that the existing elastic parts are easy to deform, and the problem that the deformation of the elastic parts causes low connector connection reliability.

[0005] According to one aspect of the utility model, the present application provides an elastic connector of a radio frequency coaxial connector, wherein the elastic connector includes a tubular body, and a plurality of through grooves are axially opened on the tube body at one end of the tubular body, and the through grooves separate the end thereof into a plurality of deformation units, and adjacent deformation units can approach or move away from each other under the action of radial external force; a first corrugated fold is provided on the circumference of the tube body away from the deformation unit, or a corrugated fold ring is coaxially provided at one end of the tubular body away from the deformation unit; the first corrugated fold and the corrugated fold ring can deform and expand and contract along the axial direction under the action of external force.

[0006] The above technical solution conceived by this application, compared with the existing technology, optimizes the structure of the RF coaxial elastic connector. Multiple spaced-apart deformation units are provided on one end, enabling radial deformation of the RF coaxial elastic connector. Circumferential corrugations are provided on the other end, enabling axial expansion and contraction of the RF coaxial elastic connector. This enables the RF coaxial elastic connector to generate radial and axial restoring forces within the installation space, preventing deformation caused by external forces and thus extending its service life.

[0007] Furthermore, the corrugated ring and the tubular body are separate. This arrangement aims to improve assembly flexibility and convenience.

[0008] Furthermore, the corrugated ring is an open C-shaped ring, and a second corrugated fold is provided on the open C-shaped ring along the circumference. The purpose of this arrangement is to enable the tube body to deform and generate counter pressure when subjected to radial force, thereby improving the recycling rate of the elastic connector.

[0009] Furthermore, the first corrugation comprises at least two corrugations, and their longitudinal cross-section is a continuous V-shape or a continuous arc shape. The arc-shaped corrugation provides a smoother stress distribution for the elastic connector, reduces stress concentration, and helps to improve the fatigue life of the elastic connector. The V-shaped corrugation is easy to manufacture and process, and has good energy absorption performance under axial impact loads, which can effectively reduce the initial peak load, reduce the fluctuation amplitude of the impact force, and improve the fatigue life of the elastic connector.

[0010] Furthermore, the end of the deformation unit is provided with a stop structure that bends outward along the radial direction of the tubular body. The purpose of providing the stop structure is to increase the radial stability of the elastic connector, making it more stable when subjected to external pressure and less likely to deform or damage.

[0011] Furthermore, the stop structure is solid or hollow. The solid stop structure has higher structural strength, while the hollow structure has a greater degree of elastic deformation.

[0012] Furthermore, a limiting base extending radially outward is provided on the end of the tubular body away from the deformation unit, which can ensure that the tubular body and the rear housing of the RF coaxial connector are firmly in contact.

[0013] According to another aspect of the present invention, a radio frequency coaxial connector is also disclosed, comprising a coaxial cable connector, a front shell, a rear shell and an elastic connector as described in any one of the above items, wherein the coaxial cable connector comprises an inner conductor, an insulating layer and an outer conductor in sequence from the inside to the outside, a portion of the outer conductor is exposed, and the other portion is covered with a protective cover; the rear shell is sleeved on the outside of the coaxial cable connector, and a limiting boss is circumferentially provided on its inner wall, the limiting boss divides the rear shell into a connecting section and a accommodating section, the connecting section is sleeved on the outside of the protective cover, the accommodating section is connected to the front shell, and cooperates with the front shell and the exposed portion of the outer conductor to form a deformation space; the elastic connector is sleeved on the exposed portion of the outer conductor, is located in the deformation space and is tightly embraced by the accommodating section, the end of the tubular body away from the deformation unit abuts against the limiting boss, and the end of the exposed portion of the outer conductor is squeezed and fixed between the deformation unit and the front shell.

[0014] Through the above technical solution conceived in the present application, compared with the existing technology, the RF coaxial elastic connector is confined in the deformation space formed by the cooperation of the front shell and the rear shell. When axial pressure is continuously applied to the rear shell to make it tightly connected with the front shell, the elastic part will be subjected to axial pressure and the deformation unit will be subjected to radial pressure. The elastic part itself generates the required positive pressure and can release stress in the deformation space to extend the life of the elastic connector.

[0015] Furthermore, the RF coaxial connector according to claim 1 is characterized in that a limiting base extending radially outward is provided on the end of the tubular body away from the deformation unit, and the limiting boss is located between the protective cover and the limiting base and abuts against the limiting base.

[0016] Furthermore, a first sealing ring is provided between the first corrugation and the outer conductor, and a second sealing ring is provided between the limiting boss and the limiting base. This arrangement can prevent external moisture and dust from entering the deformation space, thereby ensuring the connection reliability of the RF coaxial connector.

[0017] In general, the above technical solutions conceived by this application have the following technical advantages compared with the existing technologies:

[0018] 1. The present application changes the structural design of the elastic connector so that a deformation unit formed by a plurality of through grooves is provided at the end of the tubular body, so that the tubular body can be deformed when subjected to radial external force; at the same time, corrugated folds are provided on the tube body, or a corrugated fold ring is coaxially provided at the end away from the deformation unit, so that the tubular body can be deformed when subjected to axial pressure; the elastic connector as a whole can be deformed in both the axial and radial directions under the action of external force and generate the required positive pressure. Even if it is repeatedly installed, the elastic connector can maintain a continuous and stable positive pressure, thereby extending the service life of the elastic connector and further improving the durability of the product.

[0019] 2. If a corrugated ring is provided at one end of the elastic connector in this application, the corrugated ring and the tubular body are designed to be split, that is, the tubular body and the corrugated ring are coaxially arranged and the ends are in contact with each other, which is a split structure that is easy to process and flexible to install.

[0020] 3. In this application, the corrugated ring is designed as an open C-shaped tube, so that the corrugated tube can undergo certain deformation in both radial and axial directions to generate the required positive pressure, and can still maintain good restoring force after repeated use.

[0021] 4. In the present application, the corrugations on the corrugated folds include at least two, and the longitudinal section of the corrugated folds is designed to be a continuous V-shape or a continuous arc shape. The setting of the arc-shaped corrugations can provide a smoother stress distribution for the elastic connector, reduce stress concentration, and help to improve the fatigue life of the elastic connector; the V-shaped corrugated folds are easy to manufacture and process, and have good energy absorption performance under axial impact loads, which can effectively reduce the initial peak load, reduce the fluctuation amplitude of the impact force, and improve the fatigue life of the elastic connector.

[0022] 5. The elastic connector in the RF coaxial connector provided in this application can deform in the axial and radial directions and generate positive pressure. Therefore, there is no need to control the torque when the front shell and the rear shell are installed together. They can be directly installed using an ordinary wrench, and the front shell and the rear shell can be completely abutted without leaving any installation gap. On the one hand, it reduces the installation problems caused by improper torque and enhances the connection stability and reliability. On the other hand, it simplifies the installation process and improves the installation efficiency.

[0023] 6. The RF coaxial connector provided in this application has a first sealing ring arranged between the corrugated folds of the elastic connector and the outer conductor, and a second sealing ring arranged between the limiting boss and the limiting base, which can achieve double sealing of the RF coaxial connector inside to prevent water, moisture and dust.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] Example 1

[0037] This embodiment provides an elastic connector of a radio frequency coaxial connector, such as Figure 1-2As shown, the RF coaxial elastic connector includes a tubular body 1, and a plurality of through grooves 2 are axially provided on one end of the tubular body 1. The through grooves 2 divide the tubular body at one end of the tubular body 1 into a plurality of deformation units 3. The ends of adjacent deformation units 3 are separated and can approach and move away from each other under the action of radial external force; a first corrugated fold 4 is also circumferentially provided on the tubular body at the other end of the tubular body 1, and the first corrugated fold 4 can deform and expand along the axial direction under the action of external force.

[0038] Specifically, the tubular body 1 can be made of an elastic non-metallic material, a metallic material, or an alloy material. The aforementioned through-slots 2 are rectangular slots, and the multiple deformation units 3 are evenly and spaced apart. The through-slots 2 between each of the deformation units 3 serve as deformation spaces 11. Because the through-slots 2 are spaced apart between the deformation units 3, when the ends of the deformation units 3 are subjected to radial external forces, the ends of the deformation units 3 can move closer to and farther from each other. More specifically, when subjected to radially inward external forces, the ends of the deformation units 3 can move closer to and farther from each other, and when subjected to radially outward external forces, the ends of the deformation units 3 can move away from each other.

[0039] In this embodiment, Figure 2 As shown, the first corrugation 4 comprises at least two turns of corrugation, and the interconnected adjacent corrugations form a continuous V-shaped corrugation in its longitudinal cross-section. The multiple corrugations provide additional flexibility and elasticity, making the tubular body 1 more stable and adaptable to axial and angular displacements. This improves the structural stability and reliability, allowing the elastic connector to maintain stable performance over long periods of use and reducing maintenance costs.

[0040] In this embodiment, Figure 2 As shown, the end of the deformation unit 3 is provided with a stop structure 31 that is bent and protruded outward along the radial direction of the tubular body 1, and the stop structure 31 is hollow.

[0041] Specifically, the stopper structure 31 is an open, curled structure formed by the outward extension of the end of the deformable unit 3. Because this open, curled structure is hollow in the center, its outer surface is composed of multiple, sequentially connected flat surfaces. When squeezed, the stopper structure deforms to a certain extent, generating a continuous counterpressure that provides a stable connection between the coaxial cable and the connector. The hollow stopper structure is deformable, and compared to a solid structure, it can reduce weight and processing costs while maintaining the required structural strength.

[0042] In this embodiment, a limit base 12 is provided at the end of the tubular body 1. The limit base 12 extends radially outward or inward along the tubular body 1, and its outer diameter is less than or equal to the outer diameter of the annular array composed of the multiple deformation units 3. Specifically, the limit base 12 is an annular boss provided on the circumferential outer edge of the end of the tubular body away from the deformation units 3. This annular boss provides a larger contact surface between the elastic connector and the rear housing, ensuring a secure installation.

[0043] Example 2

[0044] This embodiment provides an elastic connector of a radio frequency coaxial connector, which is different from the embodiment 1 in that: Figure 3 As shown, the aforementioned stop structure 31 is solid, that is, the stop structure 31 is a protrusion arranged on the circumferential outer edge of the end of the deformation unit 3, and the outer surface of the protrusion is an arc surface, which can make the elastic connecting component structurally stronger and less prone to damage.

[0045] The cross section of the first corrugated fold 4 on the elastic connector is a continuous arc-shaped corrugated fold. The setting of the arc-shaped corrugation can provide a smoother stress distribution for the elastic connector, reduce stress concentration, and help to improve the fatigue life of the elastic connector.

[0046] Example 3

[0047] This embodiment provides an elastic connector for a radio frequency coaxial connector, which is different from the first and second embodiments in that: Figure 4 and 5 As shown, a corrugated ring 5 is coaxially arranged at one end of the tubular body 1 away from the deformation unit 3. The corrugated ring 5 and the tubular body 1 are separate, and the limiting base 12 abuts against one end of the corrugated ring 5, and the outer diameters of the abutting ends of the two are the same.

[0048] The corrugated ring 5 is a corrugated ring with a relatively small height. It is provided with N-shaped corrugations 15 along the circumference, and the N-shaped corrugations 15 are concave radially inward, and its longitudinal cross-section is N-shaped. The minimum diameter of the inner side of the corrugated ring is close to the diameter of the tubular body 1, with the exposed end that can pass through the outer conductor 8 being the main part. The bottom of the corrugated valley of the N-shaped corrugation 15 is located at about one-third of the height of the corrugated ring 5, and the bottom of the valley of the N-shaped corrugation 15 is close to the tubular body 1, so that the trumpet-shaped opening end inside the corrugated ring 5 serves as the introduction port for the cable. An annular docking seat 17 is also provided at the introduction port, extending radially into the corrugated ring 5, and the inner diameter is almost the same as the inner diameter of the tubular body 1, with the outer conductor 8 being the main part. The annular docking seat 17 is used to more firmly abut against the rear shell during assembly, and has the same function as the limiting base 12 in Example 1.

[0049] In this embodiment, the circumferential outer edge of the end of the deformation unit 3 is also provided with a stop structure 31 extending and protruding outward. The stop structure 31 in this embodiment is solid, and its outer surface is a multi-fold surface formed by multiple planes connected in sequence. It can cooperate with the internal space of the front shell of the RF coaxial connector to more reliably squeeze and fix the end of the outer conductor 8, and the structural stability is stronger.

[0050] In other preferred embodiments, the corrugated ring 5 may also be a corrugated tube with a regular shape and symmetrical corrugations.

[0051] Example 4

[0052] The elastic connector provided in this embodiment is different from the aforementioned embodiment 3 in that: Figure 6-7 As shown, the corrugated ring 5 is provided with an opening to form an open C-shaped ring 16 .

[0053] The open C-shaped ring 16 is circumferentially provided with second corrugations 51, each of which has a radially inwardly concave arc-shaped cross-section. Because the open C-shaped ring 16 has an opening, when subjected to a radially inward external force, it contracts until the two ends of the opening abut against each other, exerting a certain restoring force.

[0054] Example 5

[0055] This embodiment discloses a radio frequency coaxial connector, such as Figure 8 As shown, it includes a coaxial cable connector, a front shell 9, a rear shell 10 and the elastic connector as in the aforementioned embodiment 1. The coaxial cable connector includes an inner conductor 6, an insulating layer 7 and an outer conductor 8 from the inside to the outside. A portion of the outer conductor 8 is exposed, and the other portion is covered with a protective cover 18.

[0056] The aforementioned rear housing 10 is sleeved on the outside of the coaxial cable connector. Figure 9 As shown, the inner wall is provided with a limiting boss 101, which divides the rear housing 10 into a connecting section 102 and an accommodating section 103. The connecting section 102 is sleeved on the outside of the protective sleeve 18, and the accommodating section 103 is connected to the front housing 9 and cooperates with the front housing 9 and the exposed portion of the outer conductor 8 to form a deformation space 11.

[0057] The elastic connecting piece is sleeved on the exposed part of the outer conductor 8, is located in the deformation space 11 and is tightly embraced by the accommodating section 103, and the end of the tubular body 1 away from the deformation unit 3 abuts against the limiting boss 101, and the end of the exposed part of the outer conductor 8 is squeezed and fixed between the deformation unit 3 and the front shell 9.

[0058] Specifically, in this embodiment, the front housing 9 has a hole for passing the inner conductor 6 and a stepped hole 91 for accommodating the insulating layer 7. The inner periphery of the front housing 9 is also provided with a slot 92 for inserting the rear housing 10. The longitudinal cross-section of the slot 92 is V-shaped with a wide opening and a narrow bottom. The end surface of the rear housing 10 also has an inclined surface that matches this V-shape. A locking nut 19 is assembled on the end of the front housing 9 away from the rear housing. The locking nut 19 is used to mate with an external device to securely connect the connector to the external device.

[0059] The inner conductor 6 passes through the cable connector and is inserted into the hole in the front shell 9. An RF support 20 is also provided between the front shell 9 and the inner conductor 6. The RF support 20 is sleeved on the outside of the inner conductor 6, with one end abutting the end of the insulating layer 7 and the other end abutting the boss on the inner wall of the front shell 9. The outer wall of the RF support 20 is in close contact with the inner wall of the front shell 9, and is used to support the inner conductor 6 and ensure the coaxiality of the inner conductor 6 and the outer conductor 8, which is crucial for maintaining the electrical performance of the connector. More specifically, the interior of the RF support 20 is hollow and has an inner and outer double-sleeve structure. The RF support 20 can provide good insulation between the inner conductor 6 and the outer conductor 8, preventing current from flowing directly from the inner conductor to the outer conductor, thereby ensuring that the signal can be transmitted along the predetermined path.

[0060] During installation, the rear housing 10 is pushed toward the front housing 9, so that the end of the rear housing 10 enters the slot 92 and fits securely with the front housing 9 until the ends of the two abut and cannot move any closer. At this point, under the pushing action of the rear housing 10, the end of the deformation unit 3 squeezes the end of the outer conductor 8 onto the front housing.

[0061] In this embodiment, the limiting boss 101 is located between the protective cover 18 and the limiting base 12. The limiting boss 101 is a whole annular boss that can tightly abut against the limiting base 12 under the action of an external force. In other embodiments, the limiting boss 101 can also be a plurality of independent small bosses distributed annularly on the inner circumferential wall of the rear housing.

[0062] In this embodiment, a first sealing ring 13 is provided between the first corrugated fold 4 and the outer conductor 8, and a second sealing ring 14 is provided between the limiting boss 101 and the limiting base 12. The two sealing rings form a double sealing effect, thereby achieving a waterproof, dustproof and moisture-proof sealing effect for the RF coaxial connector.

[0063] In other preferred embodiments, when the aforementioned connector uses any one of the elastic connectors in embodiments 1-4, the lengths of the front shell 9 and the rear shell 10 thereof match the lengths of the elastic connector.
