Description

Technical Field

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

[0002] As a component for electrically connecting or separating transmission lines, RF coaxial connectors (RF connectors) are mechatronic products. In addition, the adjustment methods of other adjustable connection torque connectors are relatively complicated.

[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 and not damage the elastic parts in the rear shell, the front shell and the rear shell cannot be completely tightened and abutted during actual installation, and a certain gap must be reserved between the two. However, the size of the 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, the elastic parts will deform after multiple installations, thereby affecting their service life and further affecting the connection reliability of the RF coaxial connector. Summary of the invention

[0004] In response to the defects of the prior art or the need for improvement, the present application provides an elastic connecting piece of a radio frequency coaxial connector and a connector including the same, aiming to solve the problem that the existing elastic piece is easy to deform, and the problem that the connector connection reliability is low due to the deformation of the elastic piece.

[0005] According to one aspect of the present invention, 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, wherein the through grooves separate the end at which they are located 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 corrugation is provided on the circumference of the tube body away from the deformation unit, or a corrugation ring is coaxially provided at one end of the tubular body away from the deformation unit; the first corrugation and the corrugation ring can deform and expand and contract along the axial direction under the action of external force.

[0006] Through the above technical solution conceived by the present application, compared with the prior art, by optimizing the structure of the RF coaxial elastic connector, a plurality of deformation units arranged at intervals are provided on one end, which can enable the RF coaxial elastic connector to deform in the radial direction. The other end is provided with circumferentially surrounding corrugated folds, which can enable the RF coaxial elastic connector to stretch and deform in the axial direction. As a result, the RF coaxial elastic connector can generate radial and axial restoring forces in the installation space, prevent deformation caused by external force extrusion, and thus extend its service life.

[0007] Furthermore, the corrugated ring and the tubular body are separate. The purpose of this arrangement is to improve assembly flexibility and convenience.

[0008] Furthermore, the corrugated fold 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 corrugated folds include at least two corrugations, and the longitudinal section thereof is in 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.

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

[0011] Furthermore, the stopper structure is solid or hollow. The solid stopper structure has a higher structural strength, while the hollow stopper 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. This arrangement can ensure that the tubular body and the rear housing of the RF coaxial connector are firmly connected.

[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 preceding 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 thereof is sleeved with a protective sleeve; the rear shell is sleeved on the outside of the coaxial cable connector, and a limiting boss is circumferentially arranged 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 sleeve, 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 scheme conceived by the present application, compared with the prior art, the RF coaxial elastic connector is confined in the deformation space formed by the cooperation of the two shells through 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, the deformation unit will be subjected to radial pressure, the elastic part itself will generate the required positive pressure, and the stress can be released in the deformation space to extend the life of the elastic connector.

[0015] Furthermore, the RF coaxial connector as described in 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 sleeve and the limiting base and abuts against the limiting base.

[0016] Furthermore, a first sealing ring is provided between the first corrugated fold 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 prior art:

[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, corrugations are provided on the tube body, or a corrugated corrugation 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, so that the elastic connector can maintain a continuous and stable positive pressure even after repeated installation, 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 the present 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 the present 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 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 the present 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 the present 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, so as to realize double sealing inside the RF coaxial connector to prevent water, moisture and dust.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] Example 1

[0037] This embodiment provides an elastic connector of a radio frequency coaxial connector, such as Figure 1-2As shown, the radio frequency 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 material of the tubular body 1 can be a non-metallic material, a metal material or an alloy material with elasticity. The aforementioned through groove 2 is a rectangular groove, and a plurality of deformation units 3 are arranged evenly and at intervals. The through grooves 2 between two deformation units 3 serve as deformation spaces 11. Since the through grooves 2 are arranged at intervals between the deformation units 3, when the ends thereof are subjected to radial external forces, the ends of the deformation units 3 can approach and move away from each other; more specifically, when subjected to radially inward external forces, the ends of the deformation units 3 can approach and shrink each other, and when subjected to radially outward external forces, the ends of the deformation units 3 can move away from each other and separate.

[0039] In this embodiment, Figure 2 As shown, the first corrugated fold 4 is provided with at least two circles of corrugations, and the adjacent corrugations are connected to each other so that the longitudinal section thereof forms a continuous V-shaped corrugated fold. The multiple corrugations can provide additional flexibility and elasticity, making the structure of the tubular body 1 more stable, and being able to better adapt to axial and angular displacements, thereby improving the stability and reliability of the structure, and enabling the elastic connector to maintain stable performance under long-term use, thereby reducing maintenance costs.

[0040] In this embodiment, Figure 2 As shown, a stop structure 31 is disposed at the end of the deformation unit 3 and is bent and protruded radially outwardly along the tubular body 1, and the stop structure 31 is hollow.

[0041] Specifically, the stopper structure 31 is an open curling structure formed by the end of the deformation unit 3 extending outward and bending. Since the middle of the open curling structure is hollow, the outer surface is composed of multiple planes connected in sequence; the stopper structure will produce a certain deformation after being squeezed, thereby generating a continuous counter pressure, which can provide a stable bonding force for connecting the coaxial cable and the connector. The hollow stopper structure is deformable, and the hollow structure can reduce weight and save processing costs compared to the solid structure, while maintaining the required structural strength.

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

[0043] Example 2

[0044] The elastic connector of a radio frequency coaxial connector provided in this embodiment is different from that in 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 member structure 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] The elastic connector of a radio frequency coaxial connector provided in this embodiment is different from that in Embodiments 1 and 2 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 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, and the exposed end that can pass through the outer conductor 8 is mainly used. The corrugated valley bottom of the N-shaped corrugation 15 is located at about one-third of the height of the corrugated ring 5, and the valley bottom 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 of 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, so that the outer conductor 8 can be passed through. The annular docking seat 17 is used to more firmly abut with 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, which 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 pleated 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 above-mentioned embodiment 3 in that: Figure 6-7 As shown, the corrugated pleated ring 5 is provided with an opening to form an open C-shaped ring 16 .

[0053] The open C-shaped ring 16 is provided with a second corrugated fold 51 on its circumference, and the cross section of the second corrugated fold 51 is an arc shape that is concave radially inward. Since the open C-shaped ring 16 has an opening, when it is subjected to a radially inward external force, the open C-shaped ring 16 will shrink until the two ends of the opening abut against each other, and the open C-shaped ring 16 has a certain restoring force during this process.

[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 part of the outer conductor 8 is exposed, and the other part is covered with a protective cover 18.

[0056] The aforementioned rear housing 10 is sleeved on the outside of the coaxial cable connector. Fig. 9 As shown, the inner wall is provided with a limiting boss 101 in the circumferential direction, and the limiting boss 101 divides the rear housing 10 into a connecting section 102 and a receiving section 103. The connecting section 102 is sleeved on the outside of the protective sleeve 18, and the receiving section 103 is connected to the front housing 9, and cooperates with the front housing 9 and the exposed part 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, and is located in the deformation space 11 and is held tightly by the accommodating section 103. 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 is provided with a hole for the inner conductor 6 to pass through, and a stepped hole 91 for accommodating the insulating layer 7. The inner wall periphery is also provided with a slot 92 for inserting the rear housing 10, and the longitudinal section of the slot 92 is a V-shaped shape with a wide opening and a narrow bottom, and the end face of the rear housing 10 is also an inclined surface that matches the V-shaped shape. A locking nut 19 is assembled on one end of the front housing 9 away from the rear housing, and the locking nut 19 is used to cooperate with an external device to fasten 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 against the end of the insulating layer 7 and the other end abutting against 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 essential 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 and fixes with the front housing 9 until the ends of the two abut against each other and cannot get any closer. At this time, under the pushing action of the rear housing 10, the end of the deformation unit 3 squeezes the end wire of the outer conductor 8 and fixes it on 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, and the annular boss can be tightly abutted against the limiting base 12 under the action of external force; in other embodiments, the limiting boss 101 can also be a plurality of independent small bosses distributed in an annular shape on the circumferential wall of the inner wall of the rear housing.

[0062] In this embodiment, a first sealing ring 13 is arranged between the first corrugated fold 4 and the outer conductor 8, and a second sealing ring 14 is arranged between the limiting boss 101 and the limiting base 12. The two sealing rings form a double sealing effect to achieve 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 length dimensions of the front shell 9 and the rear shell 10 thereof match the length dimensions of the elastic connector.
