Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency cable testing, in particular to a radio frequency cable testing system. Background Art

[0002] A radio frequency coaxial cable is a cable for transmitting electromagnetic energy within the radio frequency range, and is an indispensable component in various radio communication systems and electronic devices. It is commonly used for connecting devices such as wireless communication and radio and television equipment. The performance of the radio frequency cable directly affects the quality and stability of signal transmission. Therefore, during the production and use process, strict testing of the radio frequency cable is required. The electrical performance of a radio frequency coaxial cable usually needs to measure S parameters through a vector network analyzer to reflect the characteristics of the reflected signal / transmitted signal within the frequency domain range. The most important mechanical performance index of a radio frequency coaxial cable is the minimum bending radius, which is the minimum radius value allowed for bending when the cable is in use. Excessive bending will cause cable damage and lead to a decline in electrical performance.

[0003] When the existing vector network analyzer measures a cable, it is necessary to gradually manually tighten the nuts of the two SMA interfaces of the radio frequency cable through a torque wrench to tightly connect them to the two ports of the vector network analyzer. After that, hold both ends of the cable to complete the measurement process. However, there are some defects in the existing measurement method. One is that holding both ends of the cable cannot ensure that the bending radius is always greater than the requirement of the minimum bending radius, which results in inaccurate S parameter measurement results. The other is that the operation of manually locking the two connector interfaces on the cable to be tested is time-consuming and laborious, with low efficiency and unable to meet the large-scale detection requirements.

[0029] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0030] As Figures 1 to 4 shown, this embodiment provides a radio frequency cable test system for measuring a cable under test. The radio frequency cable test system includes a fixed module 200, a movable module 300, and a control module 100. The movable module 300 is movably connected to the fixed module 200. The movable module 300 can move relative to the fixed module 200 between a test position and an assembly position. The cable under test is detachably fixed to the movable module 300 in a state of minimum bending radius. The control module 100 is connected to a signal transmitter and a signal receiver. The control module 100 transmits a signal through the signal transmitter and receives a signal through the signal receiver. When the movable module 300 is in the test position, the signal transmitter and the signal receiver are electrically connected to both ends of the cable under test respectively. Specifically, when the movable module 300 is in the assembly position, both ends of the cable under test are separated from the signal transmitter and the signal receiver.

[0031] The radio frequency cable test system adopts the limitation of positioning the cable under test on the movable module 300 in a state of minimum bending radius, which meets the mechanical performance index of the S-parameter measurement of the cable under test. Thereby, it ensures the accuracy of the S-parameter measurement of the radio frequency cable and ensures that the radio frequency cable test system can quickly and accurately measure the performance of the cable under test. At the same time, the movable module 300 can move relative to the fixed module 200 between the test position and the assembly position. This enables the radio frequency cable test system to realize the quick connection and disconnection between the cable under test and the control module 100 by changing the position of the cable under test, replacing the conventional assembly method of the cable under test, accelerating the test speed, reducing the workload of the operator. The radio frequency cable test system has a simple structure and is easy to operate, greatly improving the measurement efficiency of the radio frequency cable. In summary, the radio frequency cable test system has the advantages of simple operation, high test efficiency, and accurate measurement results, can meet the requirements of large-scale production and rapid detection of the cable under test, and provides strong technical support for the production and use of radio frequency cables. At the same time, the detachable and fixed design of the cable under test on the movable module 300 can reduce the risk of position deviation of the cable under test during the test process, thus ensuring the accuracy of the measurement results and reducing the probability of test failure.

[0032] In this embodiment, the fixed module 200 includes a fixed seat 201 and two quick-connect connectors 202. The quick-connect connectors 202 are fixedly connected to the fixed seat 201. The signal transmitter and the signal receiver are respectively connected to one quick-connect connector 202. When the movable module 300 is in the test position, the two end parts of the cable under test are respectively inserted into the two quick-connect connectors 202. When the movable module 300 is in the assembly position, the two end parts of the cable under test are disengaged from the two quick-connect connectors 202. The setting of the quick-connect connectors 202 ensures the matching effect between the signal transmitter and the signal receiver and the end parts of the cable under test, optimizes the electrical connection mode between the signal transmitter and the signal receiver and the cable under test, simplifies the difficulty of connection and disconnection between the control module 100 and the cable under test, thereby facilitating the quick transmission and test of signals and shortening the test time.

[0033] Exemplarily, the movable module 300 includes a movable seat 302, a receiving track 301 connected to the movable seat 302, and two interface fixing members 303. The movable seat 302 is movably connected to the fixed module 200. The interface fixing member 303 is provided with a fixing hole 3031 therethrough. The receiving track 301 has a receiving through groove penetrating from one end to the other end thereof. Both ends of the receiving through groove correspond to a fixing hole 3031 respectively. The receiving through groove is configured to receive the cable under test, so that the cable under test is in a state of minimum bending radius. Specifically, the movable seat 302 is movably connected to the fixed seat 201, and the receiving through groove is arranged in a U shape. The cable under test arranged in the receiving through groove is in a state of minimum bending radius. By means of the positioning design of the receiving track 301 and the two interface fixing members 303 for the cable under test, the cable under test can be conveniently installed on the movable module 300 and maintained in a stable U-shaped configuration, so as to ensure that the cable under test is in a state of minimum bending radius, which is thus beneficial to signal transmission and testing.

[0034] Further, the interface fixing member 303 is further provided with a guiding hole 3032. Two guiding protrusions 203 protrude from the fixed module 200. The guiding holes 3032 and the guiding protrusions 203 correspond to each other one by one. When the movable module 300 is in the test position, the guiding protrusion 203 penetrates through the guiding hole 3032. When the movable module 300 is in the assembly position, the guiding protrusion 203 disengages from the guiding hole 3032. Specifically, the guiding hole 3032 is a blind hole; the guiding protrusion 203 protrudes from the fixed seat 201. The structural cooperation between the guiding protrusion 203 and the guiding hole 3032 can ensure that when the cable under test is being tested, the guiding protrusion 203 penetrates through the guiding hole 3032, thereby playing a role in positioning and guiding the movable module 300 and the cable under test arranged thereon, ensuring that the interface of the cable under test is aligned with the quick-connect connector 202, and guaranteeing the tight fit between the quick-connect connector 202 and the cable under test.

[0035] In this embodiment, the movable module 300 further includes at least one locking block 304. The locking block 304 is hinged to the receiving track 301. The locking block 304 has a locking block through groove; the locking block 304 can rotate relative to the receiving track 301 between a locking position and an avoidance position. When the locking block 304 is in the locking position, the locking block through groove and a part of the receiving through groove enclose a positioning hole, and the hole wall of the positioning hole is in close contact with the surface of the cable under test. When the locking block 304 is in the avoidance position, the locking block through groove disengages from the receiving through groove.

[0036] By rotating the locking block 304 relative to the accommodating track 301 between the locking position and the avoidance position, the locking block 304 in the locking position can fix the cable to be tested in the accommodating through groove, and unlock it by moving the locking block 304 to the avoidance position after the test. The above structure is simple and reliable and occupies little space, enabling selective locking of the cable to be tested placed on the movable module 300, thereby improving the positioning effect and efficiency of the cable to be tested, reducing the fixing difficulty of the cable to be tested, and contributing to further improving the test efficiency.

[0037] In this embodiment, the locking block 304 is hinged to the accommodating track 301 through a hinge member 305. Specifically, the hinge member 305 is a hinge, and the locking block 304 can rotate relative to the accommodating track 301 around the axis of the hinge.

[0038] Exemplarily, a driving assembly is provided on the fixed module 200, and the driving assembly is used to drive the movable module 300 to move between the test position and the assembly position. Specifically, the driving assembly is arranged on the fixed module 200; the movement of the movable module 300 relative to the control module 100 enables the cable to be tested to approach or move away from the quick-connect connector 202. By setting the driving assembly, the working intensity of the operator is reduced, enabling the operator to easily adjust the position of the cable to be tested and achieve fast and accurate testing. At the same time, the driving assembly is easy to control, which helps to improve the automation level of the RF cable test system.

[0039] In an implementation manner of this embodiment, the driving assembly includes a first driving unit 205 and a ball screw 206 connected to the output end of the first driving unit 205. The first driving unit 205 is used to drive the ball screw 206 to rotate around the axis of the ball screw 206, and the ball screw 206 is in transmission connection with the movable module 300.

[0040] By using the first driving unit 205 and the ball screw 206, the driving assembly can smoothly drive the movable module 300. The above improvements ensure the working stability of the RF cable test system, reduce the occupied space, and ensure the long-term stable operation of the cable to be tested.

[0041] Specifically, the movable module 300 has a screw thread hole, and the ball screw 206 is in transmission connection with the screw thread hole.

[0042] Further, a guide rail 204 is provided on the fixed module 200. The guide rail 204 extends along the length direction of the ball screw 206. The movable module 300 is slidably disposed on the guide rail 204, and the control module 100 is located at one end of the guide rail 204. Specifically, the guide rail 204 is provided on the fixed seat 201. The design that the guide rail 204 extends along the length direction of the ball screw 206 ensures the smooth sliding of the movable module 300 on the fixed seat 201, and ensures that the movable module 300 can move along a predetermined trajectory.

[0043] Specifically, a quick-connect connector 202 is provided at one end of the guide rail 204. The above limitations optimize the structural layout of the RF cable test system, help simplify the structure of the RF cable test system, and further reduce the space occupied by the RF cable test system.

[0044] In another implementation manner of this embodiment, the driving assembly includes a second driving unit and a conveyor belt rotatably connected to the fixed module 200. The second driving unit is used to drive the conveyor belt to move, and the conveyor belt is used to convey the movable module 300. By adopting the setting of the second driving unit and the conveyor belt, the driving assembly can smoothly drive the movable module 300. The above improvements also ensure the working stability of the RF cable test system, reduce the occupied space, and ensure the long-term stable operation of the cable under test.

[0045] Specifically, both the first driving unit 205 and the second driving unit are servo motors.

[0046] Exemplarily, the control module 100 is communicatively connected to the driving assembly, and the control module 100 drives the movable module 300 through the driving assembly. By adopting the scheme of the control module 100 controlling the driving assembly, the workload of the operator can be reduced, the probability of misoperation by the operator can be lowered, and at the same time, it also helps to improve the automation degree of the RF cable test system.

[0047] Further, the control module 100 includes a test component. The test component is used to process the signals received by the control module 100 to obtain measurement results. Through the process of the test component processing the received signals, accurate measurement results can be obtained. The test component can perform processing such as amplifying, filtering, and sampling on the received signals, so as to obtain the performance parameters of the cable under test.

[0048] In this embodiment, the control module 100 includes a controller 101, a network analyzer 102, a chassis 103, a display 104, a keyboard 105, and two network analyzer RF cables 106. The test component includes the network analyzer 102. The network analyzer 102 is respectively connected to the two quick-connect connectors 202 through the two network analyzer RF cables 106. One network analyzer RF cable 106 serves as a signal transmitter, and the other network analyzer RF cable 106 serves as a signal receiver.

[0049] One end of the network analyzer RF cable 106 is screwed to one end of the quick-connect connector 202, and the other end is electrically connected to the control module 100; the end of the cable to be tested is plugged into the other end of the quick-connect connector 202. In this way, when the system is powered on, the cable to be tested and the network analyzer RF cable 106 can be electrically connected, so as to perform signal testing.

[0050] The connection relationships of the controller 101, the network analyzer 102, the chassis 103, the display 104, and the keyboard 105 are conventional technical means in the art, and their setting purposes and working principles are common knowledge in the art, so they will not be elaborated here.

[0051] Specifically, the controller 101 is a NI PXIe-8135 controller, the network analyzer 102 is a Keysight M9372A vector network analyzer, the chassis 103 is a PXIe-1075 chassis, and the keyboard 105 is an industrial keyboard with a touchpad.

[0052] This embodiment also provides a method for testing an RF cable, which is applied to the above RF cable testing system, and includes the following steps: placing the cable to be tested in the receiving track 301 at a predetermined position, and inserting both ends of the cable to be tested into the fixing holes 3031; after the cable to be tested is fixed, the test component controls the driving component to work, moves the movable module 300 to the test position, and the cable to be tested is in close contact with the quick-connect connector 202, so that the cable to be tested passes through the quick-connect connector 202 and the network analyzer RF cable 106 in sequence and then is connected to the network analyzer 102; then the controller 101 runs the cable test software, controls the network analyzer 102 to send signals to start measuring the S parameters, and the cable test software judges whether the measurement result of the S parameters of the cable to be tested meets the predetermined range, and the measurement result is directly displayed as green "Pass" or red "Fail" on the display screen; after the measurement is completed, the test component controls the driving component to work, and moves the movable module 300 to the assembly position.
