Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna detection technology, specifically to a detection device for antenna connection lines. Background Technology
[0002] An antenna is a device that can convert guided waves propagating on a transmission line into electromagnetic waves propagating in free space. When transmitting signals, it converts the high-frequency current signal generated by the transmitter into electromagnetic waves and radiates them into the surrounding space; when receiving signals, it is responsible for capturing electromagnetic waves in space, restoring them to high-frequency current signals, and transmitting them to the receiver for further processing.
[0003] Antennas and receivers require dedicated connection cables for signal transmission. These antenna connection cables, also known as RF connection cables or feeders, are crucial components for connecting antennas to other RF devices. They are primarily used for transmitting RF signals. To ensure production quality, antenna connection cables are typically inspected through random sampling to ensure their characteristic impedance meets design requirements. This ensures good signal matching during transmission, reducing reflections and losses. Specialized equipment such as network analyzers is usually used. The cable under test is connected to the network analyzer, and its input impedance at a specific frequency is measured to determine if the characteristic impedance is within the specified range.
[0004] However, in practice, it has been noted that there are many types of port shapes for antenna connection cables, such as SMA, F-type, and N-type interfaces. To avoid trouble, most testing stations currently have multiple interface shapes. However, due to the limited port panel, it is impossible to cover all shapes of the connectors. Therefore, it is impossible to test antenna connection cables with all port shapes. Moreover, it takes a certain amount of time to find the port shape during connection, which affects the connection efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a testing device for antenna connection cables, which individually sets up port sockets of each shape and provides connection cables on the back. The plug-in structure on the side of the testing platform can be replaced according to different shaped port sockets, thereby satisfying the testing of antenna connection cables with all port shapes. This solves the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An antenna connection line testing device includes a cabinet, a testing platform fixedly connected to the cabinet, and a rotating disk movably connected to the testing platform. The rotating disk includes a support disk horizontally arranged with the testing platform, rotating rods symmetrically fixedly connected to the support disk, and wire clamps and fixed power supply bases respectively provided on both sides of the support disk.
[0008] The fixed power base includes an insulating base that is fixedly connected to the test bench. The insulating base has a T-shaped slot with a one-way opening, and a replaceable connector is inserted into the inside of the T-shaped slot. A locking knob is provided between the replaceable connector and the T-shaped slot.
[0009] As a further technical solution of this utility model, the replaceable connector includes an insulating socket, which is inserted into the inside of the T-shaped slot, and the side of the insulating socket is fixedly connected to an SMA interface located on the side of the insulating base.
[0010] As a further technical solution of this utility model, the insulating socket has a slot on the side near the locking knob, and the locking knob is threadedly connected to the insulating seat, and the end of the locking knob passes through the insulating seat and is inserted into the slot.
[0011] As a further technical solution of this utility model, the inner side of the insulating base is provided with mounting grooves in a rectangular array, and each mounting groove is fixedly connected with a conductive spring piece. The insulating socket is provided with a positioning groove corresponding to the conductive spring piece on the side near the mounting groove.
[0012] As a further technical solution of this utility model, each of the positioning grooves is embedded with a conductive spring corresponding to a conductive copper sheet, wherein the conductive spring is U-shaped and the side of the conductive spring is in contact with the conductive copper sheet.
[0013] As a further technical solution of this utility model, a power-on tester is also fixedly connected to the test platform. The two ends of the power-on tester are connected to the wire clamp and the fixed power-on base respectively through wires. The end of the wire passes through the insulating base and is connected to the conductive spring.
[0014] As a further technical solution of this utility model, a limiting pressure plate is also provided above the support plate, and a handle is integrally provided on the top of the limiting pressure plate. The limiting pressure plate is provided with through holes symmetrically, and the end of the rotating rod passes through the through holes opened on the limiting pressure plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This utility model allows for the rotation of a locking knob to separate the end of the locking knob from the inside of the slot. Then, the insulating socket is moved forward to remove it from the inside of the T-shaped slot. Different shaped SMA interfaces can be replaced according to the port shape of the antenna connection cable, thereby adapting to antenna connection cables with different port shapes and increasing the applicability of the device.
[0017] In this invention, when the insulating socket is inserted into the inside of the T-shaped slot, the conductive copper sheet on the side of the insulating socket makes contact with the conductive spring on the side of the T-shaped slot, thereby ensuring normal signal transmission. This makes it convenient for staff to replace the replaceable connector according to the specific model of the antenna connection cable to be tested. It is simple and quick, saves the time of finding the corresponding socket, and thus improves efficiency.
[0018] In this invention, a drive motor below the support plate drives a rotating rod to rotate. The rotating rod winds the antenna connection wire and rolls it into a disc for easy storage. It can also be used to test the effect of bending the antenna connection wire on the signal, thus increasing its functionality. Attached Figure Description

A locking knob 73 is provided between the replaceable connector 8 and the T-shaped slot 72.
[0031] In this embodiment, the replaceable connector 8 includes an insulating socket 81, which is inserted into the inside of the T-slot 72, and the side of the insulating socket 81 is fixedly connected to an SMA interface 82 located on the side of the insulating base 71.
[0032] Furthermore, the insulating socket 81 has a slot 85 on the side near the locking knob 73, and the locking knob 73 is threadedly connected to the insulating base 71, with the end of the locking knob 73 penetrating the insulating base 71 and inserted into the slot 85.
[0033] By adopting the above technical solution, rotating the locking knob 73 separates the end of the locking knob 73 from the inside of the slot 85, and then moving the insulating socket 81 forward to remove the insulating socket 81 from the inside of the T-shaped slot 72, different shapes of SMA interfaces 82 can be replaced according to the port shape of the antenna connection line, thereby adapting to the use of antenna connection lines with different port shapes, and thus increasing the application range of the device.
[0034] Furthermore, the inner side of the insulating base 71 is provided with mounting grooves 74 in a rectangular array, and each mounting groove 74 is fixedly connected with a conductive spring piece 75. The insulating socket 81 is provided with a positioning groove 83 corresponding to the conductive spring piece 75 on the side near the mounting groove 74.
[0035] More specifically, each of the positioning grooves 83 is embedded with a conductive spring 75 corresponding to a conductive copper sheet 84. The conductive spring 75 is U-shaped and its side is in contact with the conductive copper sheet 84.
[0036] By adopting the above technical solution, when the insulating socket 81 is inserted into the inside of the T-shaped slot 72, the conductive copper piece 84 on the side of the insulating socket 81 and the conductive spring piece 75 on the side of the T-shaped slot 72 make contact with each other, thereby ensuring normal signal transmission. This makes it convenient for staff to replace the replaceable connector 8 according to the specific model of the antenna connection line to be tested. It is simple and quick, saves the time of finding the corresponding socket, and thus improves efficiency.
[0037] Furthermore, a power-on detector 6 is fixedly connected to the testing platform 3. The two ends of the power-on detector 6 are connected to the wire clamp 9 and the fixed power-on base 7 respectively through wires.

[0040] The wires are placed between the symmetrical rotating rods 42, and then the servo motor drives the rotating rods 42 to rotate through the support plate 41, thereby winding the antenna connection wires into a disc shape, and storing the antenna connection wires after testing.
[0041] More specifically, the power-on detector 6 includes a radio frequency signal transmitting circuit, and a signal comparison circuit is also provided inside the power-on detector 6. The radio frequency signal generating circuit sends the signal to the antenna connection line through a wire, and the signal returns to the power-on detector 6 from the other end after being transmitted through the antenna connection line.

[0043] The working principle of this utility model is as follows: In use, firstly, the middle position of the antenna connection line is placed between the symmetrical rotating rods 42. Then, the servo motor fixedly connected to the test platform 3 drives the support plate 41 to rotate, winding the antenna connection line into a disc shape. Then, the replaceable connector 8 is replaced according to the port model of the antenna connection line. The locking knob 73 is rotated, and through the threaded engagement between the locking knob 73 and the insulating seat 71, the end of the locking knob 73 is separated from the inside of the slot 85. Then, the insulating socket 81 is moved forward and removed from the inside of the T-shaped slot 72. Then, according to the port shape of the antenna connection line, the SMA interface 82 of different shapes is replaced. The port of the antenna connection line is inserted into the SMA interface 82, while the other end of the antenna connection line is clamped in the wire clamp 9. Then, the power-on tester 6 inputs the radio frequency signal from one end of the antenna connection line. After being transmitted to the other end, the radio frequency signal returns to the power-on tester 6 through the wire. The comparison module inside the power-on tester 6 compares the transmitted signal and the received signal, and finally, the signal transmission loss is calculated.
