It includes: a housing with an antenna connected to one end; a circuit board installed inside the housing and electrically connected to the antenna; a signal transmitting module and a signal receiving module, respectively integrated on the circuit board; and a pair of shielding covers installed on the circuit board, respectively covering the signal transmitting module and the signal receiving module.

Description

Technical Field

[0001] This utility model relates to the field of electrical communication technology, specifically to a radio frequency transceiver for communication. Background Technology

[0002] Radio frequency (RF) transceivers are indispensable core components in communication systems, used to transmit and receive radio frequency (RF) signals. Existing RF transceivers typically include a housing, antenna, circuit board, and signal transmitting and receiving modules integrated on the circuit board. To avoid electromagnetic interference between the signal transmitting and receiving modules, shielding covers are usually placed on the circuit board, enclosing the signal transmitting and receiving modules separately inside the shielding covers.

[0003] In practical applications, the signal transmitting and receiving modules need to be electrically connected to external devices or other functional modules via wiring harnesses. To address this, existing technologies have wiring harness holes on the periphery of the shielding cover for the wiring harness to pass through. However, these existing technologies have the following problems and drawbacks:

[0004] First, to suppress electromagnetic interference, existing technologies typically install ferrite cores inside the wire harness holes. Ferrite cores are generally composed of two half-rings joined together, with the wire harness passing between them. When the wire harness passes through the core, it tends to sag under gravity. Over long-term use, this sag causes continuous friction between the wire harness and the shielding hole walls, and increases the gap between the wire harness and the core, potentially leading to wear on the wire harness insulation, wire core breakage, and magnetic leakage, thus affecting the signal transmission reliability of the RF transceiver.

[0005] Secondly, during the assembly process, the two ferrite half-rings are prone to rigid collisions when splicing, which can cause cracks or chipping in the ferrite material (which is relatively brittle), affecting the suppression effect and service life of the magnetic ring. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a radio frequency transceiver for communication.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A radio frequency transceiver for communication, comprising:

[0009] The housing has an antenna connected to one end.

[0010] The circuit board is installed inside the housing and is electrically connected to the antenna;

[0011] The signal transmitting module and the signal receiving module are integrated on the circuit board respectively;

[0012] A pair of shielding covers are mounted on the circuit board, respectively covering the signal transmitting module and the signal receiving module;

[0013] The wire harness hole is located on the periphery of the shielding cover and is used for the wire harness to pass through;

[0014] The first and second ferrite half-magnetic rings are installed inside the wire harness hole, and the first and second ferrite half-magnetic rings, after being spliced ​​together, together form a space for the wire harness to pass through; and,

[0015] A bushing is disposed on the inner surface of the first ferrite half-magnetic ring, and the bushing extends outward from the splicing surface of the first ferrite half-magnetic ring and the second ferrite half-magnetic ring, and covers at least a portion of the outer surface of the second ferrite half-magnetic ring.

[0016] The portion of the bushing located inside the first ferrite semi-magnetic ring forms a load-bearing structure for carrying the wire harness, while the portion of the bushing located at the splicing surface and the outer surface of the second ferrite semi-magnetic ring forms a buffer protection structure.

[0017] Preferably, there is a radial gap between the bushing and the inner wall of the first ferrite semi-magnetic ring, and the height of the gap is 2-3 mm.

[0018] Preferably, the bushing extends axially to the outside of the first ferrite semi-magnetic ring and the second ferrite semi-magnetic ring, respectively, to form a protective structure for isolating the wire harness from the ends of the first ferrite semi-magnetic ring and the second ferrite semi-magnetic ring.

[0019] Preferably, the bushing is made of an elastic material.

[0020] Preferably, the elastic material is polytetrafluoroethylene or nylon.

[0021] Preferably, the bushing has a flanged portion at one end near the first ferrite semi-magnetic ring, and the flanged portion is engaged with the end face of the first ferrite semi-magnetic ring.

[0022] Preferably, the bushing is provided with an elastic hook at one end near the second ferrite semi-magnetic ring, the elastic hook being used to detachably fix the bushing to the outer surface of the second ferrite semi-magnetic ring.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. Load-bearing and protection effect of wire harness: By setting a bushing on the inner surface of the first ferrite semi-magnetic ring and making the part of the bushing inside the first ferrite semi-magnetic ring form a load-bearing structure, when the wire harness is placed on the bushing, the bushing provides an upward load-bearing force to the wire harness. This load-bearing force can balance the downward trend of the wire harness under the action of gravity, thereby effectively reducing the friction between the wire harness and the hole wall of the shielding cover due to long-term downward movement and the excessive gap between the top of the wire harness and the inner wall of the second ferrite semi-magnetic ring, preventing the wire harness insulation layer from wearing or the wire core from breaking and the leakage of magnetic flux caused by the increased gap above.

[0025] 2. Splicing Buffer Protection Effect: By extending the bushing outward from the splicing surface of the first and second ferrite semi-magnetic rings and covering at least a portion of the outer surface of the second ferrite semi-magnetic ring, the portion of the bushing located at the splicing surface can form a buffer when the two semi-rings are spliced, avoiding rigid collisions between the ferrite materials and effectively preventing cracks or chipping of the first and second ferrite semi-magnetic rings due to collisions; at the same time, in the vibration environment during the use of the RF transceiver, the portion of the bushing located at the splicing surface and the outer surface of the second ferrite semi-magnetic ring can absorb and attenuate vibration energy, avoiding rigid impacts between the magnetic rings and the shield or wire harness.

[0036] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0037] Example

[0038] like Figure 1-8 As shown, a communication radio frequency transceiver includes a housing 1, an antenna 2, a circuit board 3, a signal transmitting module 4, a signal receiving module 5, a shielding cover 6, a wiring harness hole 7, a first ferrite semi-magnetic ring 8, a second ferrite semi-magnetic ring 9, and a bushing 10. One end of the housing 1 is connected to the antenna 2, which is used to transmit and receive radio frequency signals. The housing 1 serves as the external protective structure of the radio frequency transceiver, and its interior forms an installation space. The circuit board 3 is installed inside the housing 1 and is electrically connected to the antenna 2. Corresponding circuits and electronic components are arranged on the circuit board 3. The signal transmitting module 4 and the signal receiving module 5 are respectively integrated on the circuit board 3. The signal transmitting module 4 is used to modulate a baseband signal into a radio frequency signal and transmit it through the antenna 2. The signal receiving module 5 is used to receive the radio frequency signal through the antenna 2 and demodulate it back into a baseband signal. A pair of shielding covers 6 are installed on the circuit board 3 and respectively cover the signal transmitting module 4 and the signal receiving module 5. The shielding cover 6 is made of metal (such as copper, aluminum or nickel silver) and its function is to enclose the signal transmitting module 4 and the signal receiving module 5 in separate shielding spaces to avoid electromagnetic interference between them and ensure the purity and transmission quality of the radio frequency signal.

[0039] Specifically, such as Figure 5As shown, the wire harness hole 7 is located on the periphery of the shielding cover 6, allowing the wire harness to pass through. One end of the wire harness is connected to the signal transmitting module 4 or signal receiving module 5 inside the shielding cover 6, and the other end extends through the wire harness hole 7 to the outside of the shielding cover 6 to connect to external devices or other functional modules. The first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9 are installed inside the wire harness hole 7. Both the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9 are semi-circular ring structures. After being spliced ​​together, they form a complete circular magnetic ring, and a space for the wire harness to pass through is formed in the center of this complete magnetic ring. The ferrite magnetic ring can provide high-frequency impedance to the wire harness passing through it, thereby suppressing common-mode interference and electromagnetic noise, and improving the electromagnetic compatibility performance of the RF transceiver. The first ferrite semi-magnetic ring 8 is installed at the bottom of the wire harness hole 7 and is fixed by potting after installation.

[0040] Specifically, such as Figure 6 , Figure 7 and Figure 8 As shown, the bushing 10 is disposed on the inner surface of the first ferrite semi-magnetic ring 8. Specifically, the overall shape of the bushing 10 is adapted to the shape of the inner surface of the first ferrite semi-magnetic ring 8, and the bushing 10 is spaced within the inner wall surface of the first ferrite semi-magnetic ring 8. The bushing 10 extends outward from the splicing surface of the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9, and covers at least a portion of the outer surface of the second ferrite semi-magnetic ring 9. In other words, the bushing 10 not only covers the inner surface of the first ferrite semi-magnetic ring 8, but also extends from the splicing gap of the two semi-rings, wraps around at least a portion of the outer surface of the second ferrite semi-magnetic ring 9, and is fixed to the second ferrite semi-magnetic ring 9.

[0041] Furthermore, in this invention, the portion of the bushing 10 located inside the first ferrite semi-magnetic ring 8 forms a support structure for carrying the wire harness. When the wire harness is placed on the bushing 10 inside the first ferrite semi-magnetic ring 8, the bushing 10 provides an upward support force to the wire harness. This support force can balance the downward tendency of the wire harness under gravity, thereby effectively preventing the wire harness from rubbing against the hole wall of the shielding cover 6 due to long-term downward movement and preventing excessive gaps between the top of the wire harness and the inner wall of the second ferrite semi-magnetic ring 9. This prevents wear of the wire harness insulation layer or breakage of the wire core and magnetic leakage caused by the increased gap above. At the same time, the portion of the bushing 10 located at the splicing surface and the outer surface of the second ferrite semi-magnetic ring 9 forms a buffer protection structure. When the second ferrite semi-magnetic ring 9 and the first ferrite semi-magnetic ring 8 are spliced, the portion of the bushing 10 located at the splicing surface can form a buffer between the two semi-rings, avoiding rigid collisions between the ferrite materials and effectively preventing cracks or chipping of the ferrite semi-rings due to collisions. During use after the RF transceiver is installed, the portion of bushing 10 located on the splicing surface and the outer surface of the second ferrite semi-magnetic ring 9 can form a buffer under vibration, absorbing and attenuating vibration energy, and preventing rigid impact between the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9 and the shielding cover 6 or wire harness.

[0042] Furthermore, a radial gap exists between the bushing 10 and the inner wall of the first ferrite semi-magnetic ring 8, with the gap height being 2mm to 3mm. This gap allows the bushing 10 to have a certain radial deformation space when subjected to wire harness pressure or vibration impact, thereby further improving the cushioning effect of the bushing 10. At the same time, this gap also facilitates the threading and adjustment of the wire harness, reducing assembly difficulty.

[0043] Furthermore, the bushing 10 extends axially to the outside of the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9, respectively, to form a protective structure for preventing the wire harness from contacting the ends of the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9. That is, the axial length of the bushing 10 is greater than the total axial length of the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9 after splicing, and the two ends of the bushing 10 extend from the two ends of the magnetic rings. In this way, when the wire harness passes through the magnetic rings, the parts that contact the ends of the magnetic rings are isolated by the bushing 10, avoiding direct contact between the wire harness and the sharp edges or burrs of the ferrite material ends, thus preventing wear.

[0044] In a preferred embodiment of this utility model, the bushing 10 is made of an elastic material. The elastic material endows the bushing 10 with good cushioning performance and a certain degree of deformation capability, enabling it to better perform its dual functions of load-bearing and cushioning. Optionally, the elastic material is polytetrafluoroethylene (PTFE) or nylon. PTFE has excellent wear resistance, a low coefficient of friction, and good chemical stability, maintaining good performance during long-term use. Nylon (PA) also has good wear resistance, toughness, and elasticity, and is relatively inexpensive. Those skilled in the art can select a suitable elastic material according to actual needs.

[0045] Furthermore, the bushing 10 has a flanged portion at one end near the first ferrite semi-magnetic ring 8, which engages with the end face of the first ferrite semi-magnetic ring 8. The flanged portion allows the bushing 10 to be stably positioned on the first ferrite semi-magnetic ring 8, preventing the bushing 10 from shifting in the axial direction, and also further enhancing the isolation and protection effect of the bushing 10 on the wire harness and the end of the magnetic ring.

[0046] Furthermore, the bushing 10 is provided with a resilient hook at one end near the second ferrite semi-magnetic ring 9. This resilient hook is used to detachably fix the bushing 10 to the outer surface of the second ferrite semi-magnetic ring 9. The resilient hook creates a detachable connection between the bushing 10 and the second ferrite semi-magnetic ring 9, facilitating assembly, disassembly, and maintenance. During assembly, simply engaging the resilient hook with the outer surface of the second ferrite semi-magnetic ring 9 achieves fixation; when disassembly is required, simply pressing the resilient hook releases it.

[0047] In a preferred embodiment of this utility model, the wall thickness of the bushing 10 is 0.5mm to 1.5mm. This wall thickness range ensures that the bushing 10 has sufficient structural strength and elastic cushioning capacity, while also preventing excessive wall thickness from occupying too much internal space of the wire harness hole 7, thus ensuring that the wire harness can pass through smoothly.

[0048] Furthermore, the inner wall of the wire harness hole 7 is provided with a mounting groove, in which the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9 are embedded. The mounting groove can position and limit the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9, preventing radial displacement or axial movement of the magnetic rings within the wire harness hole 7, thereby improving the stability and reliability of the assembly.

[0049] Specifically, the following description, in conjunction with the assembly process and operating principle of this utility model, will further illustrate this utility model.

[0050] During assembly, firstly, the bushing 10 is fitted onto the second ferrite half-ring 9, and then the second ferrite half-ring 9 is spliced ​​onto the first ferrite half-ring 8. The bushing 10 must extend beyond the splicing surface and be located on the inner surface of the first ferrite half-ring 8, thus completing the assembly of the bushing 10 with the first ferrite half-ring 8 and the second ferrite half-ring 9. Then, the assembled first ferrite half-ring 8 and second ferrite half-ring 9 are installed in the predetermined positions (e.g., embedded in the mounting groove) within the wire harness hole 7 of the shielding cover 6. Next, the wire harness is passed through the bushing 10 inside the first ferrite half-ring 8 (i.e., through the bearing space formed by the bushing 10), thus completing the installation. During the splicing process, the portion of the bushing 10 extending from the splicing surface first contacts the second ferrite half-ring 9, forming a buffer to prevent direct rigid collision between the two ferrite half-rings. Finally, the elastic hooks on the bushing 10 are engaged with the outer surface of the second ferrite half-ring 9 to complete the overall assembly.

[0051] In use, the wire harness is supported by the bushing 10. The elasticity and load-bearing capacity of the bushing 10 balance the downward weight of the wire harness, preventing friction between the wire harness and the wall of the shielding cover 6, and avoiding the increase in the gap between the wire harness and the inner wall of the second ferrite semi-magnetic ring 9 due to the downward weight of the wire harness. In the vibration environment generated during the operation of the RF transceiver, the bushing 10 absorbs and attenuates the vibration energy through its own elastic deformation, providing good buffer protection for the first ferrite semi-magnetic ring 8, the second ferrite semi-magnetic ring 9, and the wire harness.

[0052] As a preferred embodiment of this utility model, in practical applications, ferrite materials with different materials and permeabilities can be selected to fabricate the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9 according to different communication frequency bands and power levels, so as to meet the electromagnetic interference suppression requirements in different scenarios. Meanwhile, the size and material of the bushing 10 can also be adaptively adjusted according to the diameter and flexibility of the wire harness to achieve the best load-bearing and buffering effect. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0053] Shielding and isolation effect: By setting a pair of metal shields 6 on the circuit board 3 to cover the signal transmitting module 4 and the signal receiving module 5 respectively, the two are enclosed in independent shielding spaces, which effectively avoids electromagnetic interference between the transmitting module and the receiving module and ensures the purity and transmission quality of the radio frequency signal.

[0054] Harness bearing and protection effect: By setting a bushing 10 on the inner surface of the first ferrite semi-magnetic ring 8, and making the part of the bushing 10 inside the first ferrite semi-magnetic ring 8 form a bearing structure, when the harness is placed on the bushing 10, the bushing 10 provides an upward bearing force to the harness. This bearing force can balance the downward tendency of the harness under the action of gravity, thereby effectively avoiding friction between the harness and the hole wall of the shielding cover 6 due to long-term downward movement, and preventing excessive gap between the top of the harness and the inner wall of the second ferrite semi-magnetic ring 9. This prevents wear of the harness insulation layer or breakage of the wire core and magnetic leakage caused by the increased gap above.

[0055] Splicing buffer protection effect: By extending the bushing 10 outward from the splicing surface of the first ferrite half-magnetic ring 8 and the second ferrite half-magnetic ring 9 and covering at least part of the outer surface of the second ferrite half-magnetic ring 9, the part of the bushing 10 located at the splicing surface can form a buffer when the two half-rings are spliced, avoiding rigid collisions between ferrite materials, and effectively preventing the first ferrite half-magnetic ring 8 and the second ferrite half-magnetic ring 9 from cracking or chipping due to collisions; at the same time, in the vibration environment during the use of the RF transceiver, the part of the bushing 10 located at the splicing surface and the outer surface of the second ferrite half-magnetic ring 9 can absorb and attenuate vibration energy, avoiding rigid impacts between the magnetic ring and the shield 6 or the wire harness.

[0056] Elastic deformation buffering effect: By maintaining a radial gap of 2mm to 3mm between the bushing 10 and the inner wall of the first ferrite semi-magnetic ring 8, the bushing 10 has sufficient radial deformation space when subjected to wire harness pressure or vibration impact, which further improves the buffering effect of the bushing 10. At the same time, this gap also facilitates the threading and adjustment of the wire harness and reduces the assembly difficulty.

[0057] End isolation protection effect: By extending the two ends of the bushing 10 in the axial direction to the outside of the first ferrite half-magnetic ring 8 and the second ferrite half-magnetic ring 9 respectively, the axial length of the bushing 10 is greater than the total axial length after the two half-rings are spliced. When the wire harness passes through the magnetic ring, the part that contacts the end of the magnetic ring is isolated by the bushing 10, avoiding direct contact between the wire harness and the sharp edge or burr of the end of the ferrite material, which would cause wear.

[0058] Elastic material cushioning effect: By using elastic materials such as polytetrafluoroethylene or nylon to make bushing 10, bushing 10 is given good cushioning performance and deformation ability, so that it can better play the dual functions of load bearing and cushioning. Among them, polytetrafluoroethylene has excellent wear resistance, low coefficient of friction and good chemical stability, while nylon has good wear resistance, toughness and elasticity and relatively low cost, which can be flexibly selected according to actual needs.

[0059] Axial positioning effect: By providing a flange at one end of the bushing 10 near the first ferrite semi-magnetic ring 8 and engaging the flange with the end face of the first ferrite semi-magnetic ring 8, the bushing 10 can be stably positioned on the first ferrite semi-magnetic ring 8, preventing the bushing 10 from moving in the axial direction, and further enhancing the isolation and protection effect of the bushing 10 on the wire harness and the end of the magnetic ring.

[0060] Removable fixing effect: By setting an elastic hook at one end of the bushing 10 near the second ferrite half-magnetic ring 9, the elastic hook can detachably fix the bushing 10 to the outer surface of the second ferrite half-magnetic ring 9, which is convenient for assembly, disassembly and maintenance. During assembly, simply engage the elastic hook with the outer surface of the second ferrite half-magnetic ring 9 to achieve fixation. During disassembly, simply press the elastic hook to release it to separate it. The operation is simple and quick.

[0061] Wall thickness optimization effect: By setting the wall thickness of bushing 10 to 0.5mm to 1.5mm, it ensures that bushing 10 has sufficient structural strength and elastic buffering capacity, while avoiding excessive occupation of the internal space of wire harness hole 7 due to excessive wall thickness, ensuring that the wire harness can pass through smoothly, and achieving an optimized balance between structural strength and space utilization.

[0062] Comprehensive protection effect: Through the assembly of bushing 10 with the first ferrite semi-magnetic ring 8 and the second ferrite semi-magnetic ring 9 respectively, the part of bushing 10 extending from the splicing surface first contacts the second ferrite semi-magnetic ring 9 to form a buffer, avoiding direct rigid collision between the two ferrite semi-rings; during use, the wire harness is supported by bushing 10, and the elasticity and load-bearing capacity of bushing 10 balance the weight of the wire harness, reducing the friction between the wire harness and the wall of the shielding cover 6 hole and the increased gap between the wire harness and the inner wall of the second ferrite semi-magnetic ring 9; in a vibration environment, bushing 10 absorbs and attenuates vibration energy through elastic deformation, providing comprehensive buffer protection for the first ferrite semi-magnetic ring 8, the second ferrite semi-magnetic ring 9 and the wire harness.

[0063] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
