Description
TECHNICAL FIELD
[0001] The embodiment of the present application relates to the field of radio frequency technology, in particular to a multi-directional conduction radio frequency test seat, a multi-core radio frequency cable and a radio frequency test device. BACKGROUND
[0002] When using an instrument to test a radio frequency signal of a radio frequency circuit, a radio frequency cable and a radio frequency test seat are often needed for measurement. One end of the radio frequency cable is connected to the instrument, and the other end of the radio frequency cable is connected to a test end of the radio frequency test seat. The test end is connected to an output end of the radio frequency circuit. The conventional radio frequency test seat cannot realize simultaneous conduction test in any direction for the radio frequency signal on the radio frequency circuit. For example, when the radio frequency test seat is not inserted into the radio frequency cable, two test ends are bidirectional conduction. When the radio frequency cable is inserted, only one-way conduction of the radio frequency signal from the radio frequency circuit to the instrument along the radio frequency cable can be realized. If the radio frequency signal output by another output end of the radio frequency circuit needs to be tested, the test seat needs to be adjusted.
[0003] Figures 1A-1C The structure diagram of each component of the conventional radio frequency test device is given. Figure 1A The sectional view of the conventional radio frequency test seat in the conventional radio frequency test device is shown in FIG. 1. Figure 1A As shown in FIG. 1, the components of the radio frequency test seat 11 at least include: an elastic arm 111, an elastic arm 112 and a test seat ground 113. The elastic arm 111 and the elastic arm 112 are made of the same conductive material and can be deformed under a certain stress.
[0004] Figure 1B The top view of the two elastic arms in the conventional radio frequency test seat is shown in FIG. 2. Figure 1B As shown in FIG. 2, the elastic arm 112 is provided with an extended spring sheet 1122 and a buckle 1121 at the end. The spring sheet 1122 is a flat thin metal sheet, and the buckle 1121 is a thickened protrusion or a curled edge at the front end of the spring sheet 1122. When the elastic arm 111 and the elastic arm 112 are in contact, the buckle 1121 on the elastic arm 112 is buckled upward from the bottom of the elastic arm 111 into the clamping hole 1111 of the elastic arm 111, so as to ensure that the elastic arm 111 and the elastic arm 112 are in contact and conduction.
[0005] Figure 1C The bottom view of the two elastic arms in the conventional radio frequency test seat is shown in FIG. 3. Figure 1C As shown in FIG. 3, the spring sheet 1122 of the elastic arm 112 extends below the clamping hole 1111 of the elastic arm 111, so that the buckle 1121 can be buckled upward from the bottom of the elastic arm 111 into the clamping hole 1111.
[0006] Figure 2 The sectional view of the conventional radio frequency cable is shown in FIG. 4. Figure 2As shown, the radio frequency cable 12 includes an inner core 121 and a cable ground 122. The inner core 121 is used to connect the elastic arm 112 with the test instrument, and the cable ground 122 is used for grounding.
[0007] Figure 3 A sectional view of the combination of the radio frequency test seat of the conventional radio frequency test device and the radio frequency cable is shown in FIG. 2. Figure 3 As shown, the conventional radio frequency test device 10 includes the combination of the radio frequency test seat 11 and the radio frequency cable 12. In a non-test state, the buckle 1121 is buckled upward in the card hole 1111, so that the elastic arm 111 and the elastic arm 112 are in the contact state S2; in a test state, when the radio frequency test seat 11 is connected to the radio frequency cable 12, the cable ground 122 and the test seat ground 113 are engaged, the cable inner core 121 pushes the spring 1122 downward, so that the buckle 1121 is separated from the card hole 1111, the elastic arm 111 and the elastic arm 112 are separated from each other, and are in the separated state S1, the inner core 121 is in contact with the elastic arm 112, so as to realize the purpose of conducting the signal on the side of the elastic arm 112 to the inner core 121. At this time, the direction of the radio frequency signal flow is: the elastic arm 112 -> the inner core 121, and the connection of the test instrument with the inner core 121 can test the radio frequency signal.
[0008] The defect of the conventional radio frequency test device is that, in the test, the radio frequency test seat 11 is unidirectional conduction in a fixed direction, and after being connected to the radio frequency cable 12, only fixed unidirectional conduction test can be performed. For example, for signal detection of a radio frequency circuit part, the elastic arm 112 end of the radio frequency test seat 11 needs to be connected to a signal transmitting port of the radio frequency circuit, and the test instrument needs to be connected to the inner core 121 for test; when the signal characteristics of a receiving end need to be detected, such as antenna side S parameter measurement, the test seat often needs to be turned by 180 degrees, or a coaxial cable is welded to guide the signal of the measured direction to the elastic arm 112 end, which will cause the research and development efficiency to be reduced, and will also introduce test error.
[0009] In the production of radio frequency antennas, consistency detection is usually required, and multiple antennas need to be detected through the transmission of multiple signals by the whole machine. If the conventional radio frequency test device 10 is used for whole machine antenna detection, a large amount of cost will be increased, and the detection efficiency is low.
[0010] The conventional radio frequency test device can also separate the contact metal arms on both sides of the test seat by additionally adding a plastic thimble after the radio frequency cable is inserted. However, the plastic thimble has certain influence on the miniaturization of the test seat and the insertion positioning of the radio frequency cable.
[0011] It can also be considered to select and adjust the direction of the test seat to realize unidirectional conduction in any direction. However, it is difficult to realize unidirectional conduction by rotating the test seat, the size requirement of the test seat for miniaturization is high, the realization is difficult, the reliability is low, and simultaneous bidirectional conduction and simultaneous test cannot be realized.
[0012] At present, there is an urgent need for a radio frequency test seat capable of multi-directional conduction or simultaneous conduction test of any single direction. SUMMARY

[0049] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0050] An embodiment of the present application provides a multi-conducting radio frequency test device, comprising a multi-conducting radio frequency test socket and a multi-core radio frequency cable, wherein the multi-conducting radio frequency test socket and the multi-core radio frequency cable are used in combination. Figures 4A-4G A structural diagram of each component of the radio frequency testing device provided in an embodiment of the present application is given.
[0051] Figure 4A This is a cross-sectional view of the multi-conducting RF test socket of the present application, as shown in FIG. Figure 4A As shown, the key components of the RF test seat 41 include at least: elastic arm 411, elastic arm 412, test seat ground 410, etc.; elastic arm 411 is the first elastic arm, and elastic arm 412 is the second elastic arm. The elastic arm 411 and the elastic arm 412 can be made of the same conductive material and can be deformed under a certain stress. In the separation state S1, the elastic arm 411 and the elastic arm 412 are separated from each other and do not contact; in the contact state S2, the elastic arm 411 and the elastic arm 412 contact each other in the contact area. The test seat ground 410 is used for grounding. The test base 41 of the embodiment of the present application is not limited to Figure 4A Design shown.
[0052] Figure 4B for Figure 4A A top view of the two elastic arms. Figure 4B As shown, when elastic arm 411 and elastic arm 412 are in contact state S2, the latch 4121 on elastic arm 412 snaps upward from the bottom of elastic arm 411 into the latch hole 4111 of elastic arm 411, thereby establishing electrical connection between elastic arm 411 and elastic arm 412. Unlike the elastic arm 111 of the conventional RF test socket 10, the elastic arm 411 provided in this embodiment of the application includes a conductive spring 4112 with a wire hole 4113 in the middle. The conductive spring 4112 connects the outer core of the RF cable to the elastic arm 411, conducting the first direction of the RF test; the wire hole 4113 allows the inner core of the RF cable to pass through. When passing through the wire hole 4113, the inner core of the RF cable is isolated from the conductive spring 4112 and connected to the elastic arm 412, conducting the second direction of the RF test. The outer core 421 of the RF cable is the first core, and the inner core 422 is the second core.
[0053] like Figure 4CAs shown, the area indicated by the dotted circle d1 is the area on the elastic arm 412 that contacts the inner core of the RF cable, and the area indicated by the dotted circle d2 is the area on the conductive spring 4112 that contacts the outer core of the RF cable.
[0054] For example, the conductive spring 4112 may be a conductive sheet of metal or alloy.
[0055] For example, the shape of the conductive spring 4112 can be as follows: Figure 4B A ring-shaped conductive spring with a wire hole 4113 in the middle; or a square / rectangular conductive spring with a wire hole in the middle. The shape and size of the conductive spring 4112 and the wire hole 4113 are not limited, as long as they can separate the inner and outer cores of the RF cable and allow the inner core to pass through.
[0056] Figure 4D FIG is a bottom view of the elastic arm 411 and the elastic arm 412. Figure 4D As shown, the spring 4122 of the elastic arm 412 extends to the bottom of the clamping hole 4111 of the elastic arm 411, so that the buckle 4121 can be clamped in the clamping hole 4111 from the bottom of the elastic arm 411 upward, so that the elastic arm 411 and the elastic arm 412 are connected and conductive.
[0057] Figure 4E This is a cross-sectional view of a multi-core radio frequency cable provided in an embodiment of the present application. Figure 4E As shown, the components of the multi-core RF cable 42 include: a first core 421, a second core 422, and a cable ground 420. The first core 421 is made of a conductive material and is wrapped around the outer layer of the second core 422. The first core 421 and the second core 422 are insulated and isolated. For example, the first core 421 can be a conductive shielding layer wrapped around the second core 422, and the second core 422 can be a conductive metal core with an insulating sheath.
[0058] Figure 4F A cross-sectional view of a multi-conducting radio frequency testing device provided in an embodiment of the present application, such as Figure 4FAs shown, the multi-conducting RF test device 40 is a combination of a multi-conducting RF test socket 41 and a multi-core RF cable 42. The multi-core RF cable 42 is connected to the RF test socket 41, and the cable ground 420 is grounded to the test socket ground 410. When both the second core 422 and the first core 421 are conductive, the second core 422 is isolated from the conductive spring 4112 passing through the elastic arm 411 and contacting the elastic arm 412. This pushes the elastic arm 412 downward, causing the elastic arms 411 and 412 to change from a contact state S2 to a separated state S1. The signal on the elastic arm 412 side is conductive to the second core 422. The first core 421 contacts the conductive spring 4112 of the elastic arm 411, and the signal on the elastic arm 411 side is conductive to the first core 421. At this point, the RF signal flows in both directions: from the elastic arm 412 to the second core 422, and from the elastic arm 411 to the first core 421. Exemplarily, the situation where the second core 422 and the first core 421 are both conductive can be that the second core 422 and the first core 421 are respectively connected to different channels of the test instrument, or the second core 422 and the first core 421 can respectively conduct two RF signals to different sampling ports.
[0059] In one feasible embodiment, the RF cable 42 is connected to the RF test socket 41, the RF cable ground 420 is engaged with the test socket ground 410 and grounded, the first end of the second core 422 is isolated and passes through the conductive spring 4112 of the elastic arm 411, contacts the elastic arm 412, and pushes the elastic arm 412 downward, so that the elastic arm 411 and the elastic arm 412 change from the contact state S2 to the separation state S1, and the first end of the first core 421 contacts the conductive spring 4112 of the elastic arm 411.
[0060] like Figure 4G As shown, when second core 422 is non-conductive and first core 421 is conductive, the signal on the elastic arm 412 side is non-conductive with the outside world after passing through second core 422, while the signal on the elastic arm 411 side is conductive with first core 421. In this case, the RF signal flow direction is unidirectional: elastic arm 411 -> first core 421. For example, when second core 422 is non-conductive and first core 421 is conductive, the second end of second core 422 can be left unconnected, while the second end of first core 421 is connected to a test channel of a test instrument, or the second end of first core 421 can conduct the RF signal to an external sampling port.
[0061] like Figure 4HAs shown, in the case that the second core 422 is conductive and the first core 421 is not conductive, the signal on the elastic arm 412 side is conducted with the second core 422 and the outside, and the signal on the elastic arm 411 side is not conducted with the outside after passing through the first core 421. At this time, the flow direction of the radio frequency signal is: elastic arm 412 -> second core 422. Exemplarily, the case that the second core 422 is conductive and the first core 421 is not conductive can be that the second end of the first core 421 is vacant, the second end of the second core 422 is connected to a test channel of a test instrument, or the second end of the second core 422 conducts the radio frequency signal to an external sampling port.
[0062] The radio frequency cable 42 provided by the embodiment of the present application is not limited to the contact between the inner core 422 and the elastic arm 412 and the contact between the outer core 421 and the elastic arm 411, and can implement contact between any elastic arm and any core.
[0063] The multi-directional conductive radio frequency test device provided by the embodiment of the present application can realize the function of one-way or two-way radio frequency test at the same time, and can improve the efficiency of antenna detection in research and development and production lines.
[0064] The multi-directional conductive radio frequency test device provided by the embodiment of the present application, the elastic arms included in the test base can not be limited to the elastic arm 411 and the elastic arm 412, and a third elastic arm can be added to realize three-port simultaneous conductive test.
[0065] Figure 5A A top view of the multi-elastic-arm test base for the multi-directional conductive third elastic arm is added. As shown in Figure 5A As shown, the test base 51 adds an elastic arm 413 in the direction perpendicular to the elastic arm 411 and the elastic arm 412. The newly added elastic arm 413 has the same or similar shape as the elastic arm 411 and has a conductive spring 4132 with a wire hole 4133 in the middle. The elastic arm 413 is referred to as a third elastic arm. Exemplarily, the conductive spring 4132 can be annular, the inner diameter of the wire hole 4133 is greater than the inner diameter of the wire hole 4113 of the elastic arm 411, and the conductive spring 4132 covers the conductive spring 4112. When the conductive spring 4132 is in contact with the conductive spring 4112, a part of the conductive spring 4112 of the elastic arm 411 is not covered by the conductive spring 4132.
[0066] As shown in Figure 5B The area shown by the dashed circle d1 is the area where the elastic arm 412 is in contact with one inner core of the radio frequency cable, the area shown by the dashed circle d2 is the area where the conductive spring 4112 is in contact with another inner core of the radio frequency cable, and the area shown by the dashed circle d3 is the area where the conductive spring 4132 is in contact with the outer core of the radio frequency cable.
[0067] Figure 5C A bottom view of the three elastic arms of the test base with the added third elastic arm. As shown in Figure 5CAs shown, the elastic arm 413 is in contact with the elastic arm 411, and the elastic arm 411 and the elastic arm 412 are in contact, the buckle 4121 on the elastic arm 412 buckles upward from the bottom of the elastic arm 411 into the card hole 4111 of the elastic arm 411, so that the elastic arm 411 and the elastic arm 412 are in conduction, thereby ensuring that the elastic arms 411, 412 and 413 are in conduction in the contact state.
[0068] The multi-core radio frequency cable provided by the embodiment of the present application is used in cooperation with the multi-directional conduction test base 51, and is not limited to the inner core 422 and the outer core 421, but can also increase one inner core.
[0069] Figure 6 The radio frequency cable with one added core is shown in a sectional view.

Figure 7 As shown, the multi-directional conduction radio frequency test device 70 is a combination of the radio frequency test base 51 and the radio frequency cable 52. When the radio frequency cable 52 is not connected, the elastic arm 411 and the elastic arm 413 of the radio frequency test base 51 are in the contact state S3, the elastic arm 411 and the elastic arm 412 are in the contact state S2, and the elastic arm 411, the elastic arm 412 and the elastic arm 413 are in conduction.
[0071] When the radio frequency cable 52 is connected to the radio frequency test base 51, the radio frequency cable ground 420 is connected to the test base ground 410, the second core 422 is in contact with the elastic arm 412, the elastic arm 412 is pushed downward, the elastic arm 411 and the elastic arm 412 are in the separation state S1, the first core 421 is in contact with the elastic arm 411, the elastic arm 411 is pushed downward, the elastic arm 411 and the elastic arm 413 are separated, and the third core 423 is in contact with the elastic arm 413.
[0072] In an implementable embodiment, when the first core 421, the second core 422 and the third core 423 are all conductive, the elastic arm 411 side signal is realized to be conductive with the first core 421, the elastic arm 412 side signal is realized to be conductive with the second core 422, and the elastic arm 413 side signal is realized to be conductive with the third core 423. At this time, the radio frequency signal flow direction is three-way: the elastic arm 412 -> the second core 422, the elastic arm 411 -> the first core 421, and the elastic arm 413 -> the third core 423. Exemplarily, the case that the first core 421, the second core 422 and the third core 423 are all conductive can be that the first core 421, the second core 422 and the third core 423 are respectively connected to the ports of different test channels of a test instrument, so as to conduct three radio frequency signals to different test channels of the test instrument respectively; or the first core 421, the second core 422 and the third core 423 are respectively connected to different sampling ports, so as to conduct three radio frequency signals to different sampling channels respectively.
[0073] In an implementable embodiment, when the first core 421 and the second core 422 are not conductive, and the third core 423 is conductive, the elastic arm 411 side signal is realized to be not conductive with the first core 421, the elastic arm 412 side signal is realized to be not conductive with the second core 422, and the elastic arm 413 side signal is realized to be conductive with the third core 423. At this time, the radio frequency signal flow direction is one-way: the elastic arm 413 -> the third core 423. Exemplarily, the case that the first core 421 and the second core 422 are not conductive, and the third core 423 is conductive can be that the first core 421 and the second core 422 are respectively vacant, and the third core 423 is connected to the port of a channel of a test instrument, so as to conduct one radio frequency signal to one test channel of the test instrument; or the first core 421 and the second core 422 are vacant, and the third core 423 is connected to a sampling port, so as to conduct one radio frequency signal to one sampling channel.
[0074] In an implementable embodiment, when the second core 422 is conductive, and the first core 421 and the third core 423 are not conductive, the elastic arm 411 is realized to be not conductive with the first core 421, the elastic arm 412 side signal is realized to be conductive with the second core 422, and the elastic arm 413 side signal is realized to be conductive with the third core 423. At this time, the radio frequency signal flow direction is one-way: the elastic arm 412 -> the second core 422. Exemplarily, the case that the second core 422 is conductive, and the first core 421 and the third core 423 are not conductive can be that the first core 421 and the third core 423 are respectively vacant, and the second core 422 is connected to the port of a channel of a test instrument, so as to conduct one radio frequency signal to one test channel of the test instrument; or the first core 421 and the third core 423 are vacant, and the second core 422 is connected to a sampling port, so as to conduct one radio frequency signal to one sampling channel.
[0075] In one implementation, when the first core 421 is on, and the second core 422 and the third core 423 are off, the second core 422 is off with the elastic arm 412, the third core 423 is off with the elastic arm 413, and the elastic arm 411 is electrically connected with the first core 421, which is the purpose of the elastic arm 411 side signal being on with the first core 421. At this time, the radio frequency signal flow direction is one-way: elastic arm 411 -> first core 421. Illustratively, when the first core 421 is on, and the second core 422 and the third core 423 are off, the second core 422 and the third core 423 can be empty respectively, the first core 421 is connected to the port of one channel of the test instrument, and one way of radio frequency signal is conducted to one test channel of the test instrument; or the second core 422 and the third core 423 are empty, and the first core 421 is connected to a sampling port, so as to conduct one way of radio frequency signal to a sampling channel.
