Description

Technical Field

[0001] The present invention relates to the technical field of port converters, and in particular to a port converter for detecting a radio frequency coaxial connector and a use method thereof. Background Art

[0002] In the RF communication industry, almost every product must be tested by instruments such as network analyzers to confirm that the electrical indicators meet the requirements before it can be shipped. Various devices under test are generally multi-port networks, and the signals transmitted by each port are different, so the form of each port is also different according to specific needs, and they have different port specifications, sizes and polarities. The ports of instruments such as network analyzers have fixed specifications and fixed polarity. Even if a test cable is installed in front of the port, the test port of the test cable also has fixed specifications and fixed polarity. When the test port of the test cable and the port of the device under test have mismatched specifications, sizes or polarities, they cannot be directly connected for testing. At this time, a converter is needed to act as a bridge in the middle. The specifications and sizes of the ports at both ends of the converter can connect the port of the device under test and the port of the test cable. Because there are many types of ports of the device under test and the test cable, it is necessary to manufacture port adapters for each combination according to the combination of the device under test port specifications and the test cable port specifications. When the number of specifications increases, the number of combinations will also increase, resulting in a large number of port converters with various types. When a port of a device needs to be tested, a converter that converts the port to the test cable port is required. If this type of converter is not prepared, the test cannot be performed, or multi-stage conversion is performed through other adapters to form a converter with the required two port specifications and polarities. In order to avoid the situation where there are no converters available, it is often necessary to prepare a large number of converters in advance for emergency use, resulting in waste of resources and increased testing costs. Summary of the invention

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] The embodiment of the present invention provides a port converter for detecting a radio frequency coaxial connector, comprising: a test end connector 1, a test end connector 2, and an intermediate conversion head 3;

[0029] like Figure 1 , 2 As shown, one end of the end connector 1 to be tested is a butt-joint end 11 to be tested that is butt-jointed with the device to be tested. The butt-joint end 11 to be tested in the figure is a cathode or an anode. The specification of the custom cathode is A11, and the specification of the anode is A12, which corresponds to the RF coaxial connector to be tested with the same port specification. The other end of the end connector 1 to be tested is a conversion end 12 to be tested that is butt-jointed with the intermediate conversion head 3. The conversion end 12 to be tested in the figure is a cathode, and the custom specification is A21. The specifications of A11, A12, and A21 are the same. The outer conductor of the butt-joint end 11 to be tested is adapted to the outer conductor of the device to be tested, and can be assembled through the outer conductor;

[0030] like Figure 3 , 4As shown, one end of the test end connector 2 is a test docking end 21 docked with the test port, the test docking end 21 in the figure is a cathode or an anode, the custom cathode specification is B11, the anode specification is B12, and the specification corresponds to the tester interface of the same port specification, the other end of the test end connector 2 is a test conversion end 22 docked with the intermediate conversion head 3, the test conversion end 22 in the figure is a cathode, the custom specification is B21, the specifications of B21, B11, and B12 are the same, the outer conductor of the test docking end 21 is adapted to the outer conductor of the tester interface, and can be assembled through the outer conductor;

[0031] like Figure 5 As shown, one end of the intermediate conversion head 3 is a first conversion docking terminal 31 that is docked with the docking terminal 11 to be tested. In the figure, the first conversion docking terminal 31 is an anode, and the custom specification is A22, and the specifications of A22 and A21 are the same; the other end is a second conversion docking terminal 32 that is docked with the test docking terminal 21. In the figure, the second conversion docking terminal 32 is an anode, and the custom specification is B22, and the specifications of B21 and B22 are the same; the outer conductor of the first conversion docking terminal 31 is adapted to the outer conductor of the docking terminal 11 to be tested, and the outer conductor of the second conversion docking terminal 32 is adapted to the outer conductor of the test docking terminal 21, and both ends can be assembled to the two ends of the intermediate conversion head 3 through the outer conductors; in order to ensure the matching of electrical performance, the insulating medium of the first conversion docking terminal 31 needs to match the electrical performance of the insulating medium of the docking terminal 11 to be tested, and the insulating medium of the second conversion docking terminal 32 needs to match the electrical performance of the insulating medium of the test docking terminal 21.

[0032] like Figure 6 As shown, the test end connector 1 and the intermediate conversion head 3 are connected through the outer conductor's screw thread. Since the specification A21 of the test conversion end 12 is the same as the specification A22 of the first conversion docking end 31, they can be well docked, and the insulating medium after docking also ensures the matching of electrical performance. Similarly, the test end connector 2 and the intermediate conversion head 3 are also connected through the outer conductor's screw thread. Since the specification B21 of the test conversion end 22 is the same as the specification B22 of the second conversion docking end 32, they can be well docked, and the insulating medium after docking also ensures the matching of electrical performance. The assembled port converter can be used as an adapter between the device under test and the tester interface.

[0033] like Figure 7 As shown, it is an intermediate conversion head 3 with different specification combinations, one end of the intermediate conversion head 3 is a conversion docking end with a custom specification of C22, and the other end is a conversion docking end with a custom specification of B22. The intermediate conversion head 3 can be used to dock the test end connector 1 with a C21 specification and the test end connector 2 with a B21 specification.

[0034] Since the port specifications of the device under test may differ greatly from the specifications of the tester interface, it is necessary to manufacture an intermediate conversion head 3 with a large difference in specifications at both ends, which will reduce the electrical performance matching of the intermediate conversion head 3 and affect the test results. Figure 8 As shown, the two ends of the intermediate docking block 4 have the same specifications and can be docked with the intermediate conversion heads 3 of the same specifications, and the two intermediate conversion heads 3 are connected through the intermediate docking block 4. The intermediate docking block 4 can connect the two intermediate conversion heads 3 and make the specifications smoothly transition during the transfer to ensure the matching degree of electrical performance.

[0035] like Fig. 9 As shown, it is a port converter connected by an intermediate docking block 4. The specification of the conversion end 12 to be tested is C21, and the specification of the test conversion end 22 is A21. The difference between the two specifications is large. Therefore, as shown in the figure, an intermediate conversion head 3 with specifications of C22 and B22, an intermediate conversion head 3 with specifications of B22 and A22, and an intermediate docking block 4 with specifications of B21 at both ends are used, so that the transition of specifications is smooth and the matching degree of electrical performance is guaranteed.

[0036] A specific embodiment of the present invention further provides a method for using the port converter for detecting a radio frequency coaxial connector, which is as follows:

[0037] Select a test end connector 1 with the same specification as the device under test and a test end connector 2 with the same specification as the tester interface.

[0038] like Figure 5 As shown, when the difference between the specification of the end connector 1 to be tested and the specification of the test end connector 2 is less than two standard specifications,

[0039] Select an intermediate conversion head 3, the first conversion docking end 31 of the intermediate conversion head 3 has the same specifications as the conversion end 12 to be tested of the selected test end connector 1, and the second conversion docking end 32 has the same specifications as the test conversion end 22 of the selected test end connector 2, dock and fix the conversion end 12 to be tested of the selected test end connector 1 with the first conversion docking end 31 of the selected intermediate conversion head 3, dock and fix the test conversion end 22 of the selected test end connector 2 with the second conversion docking end 32 of the selected intermediate conversion head 3, and complete the transfer;

[0040] like Fig. 9 As shown, when the difference between the specification of the end connector 1 to be tested and the specification of the test end connector 2 is greater than two standard specifications,

[0041] Select at least one intermediate docking block 4 and at least two intermediate conversion heads 3, dock the two intermediate conversion heads 3 with one intermediate docking block 4, the conversion docking ends between the two adjacent intermediate conversion heads 3 and the intermediate docking block 4 have the same specifications, the conversion docking ends of the intermediate conversion heads 3 at both ends have the same specifications as the conversion end 12 to be tested of the selected test end connector 1 and the test conversion end 22 of the selected test end connector 2, dock and fix the conversion end 12 to be tested of the selected test end connector 1 with the conversion docking end of the intermediate conversion head 3 at one end, dock and fix the test conversion end 22 of the selected test end connector 2 with the conversion docking end of the intermediate conversion head 3 at the other end, and complete the transfer.

[0042] The specifications in the above-mentioned “specifications” and “standard specifications” refer to the diameter size of the inner conductor and the electrical properties of the inner conductor, and the standard specifications are the diameter size of the inner conductor and the electrical properties of the inner conductor of the standard parts in this field.

[0043] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
