Testing the multifunctional bare board in advance can find and solve most problems in the multifunctional bare board testing stage and reduce the number of rework. Therefore, performance testing of multifunctional bare boards is particularly important.

[0036] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0037] like Figures 1 to 4 As shown, an RF floating integrated button mechanism 10 for multifunctional bare board testing in one embodiment includes a mounting base 100 and a RF floating integrated module 200, wherein the mounting base 100 is provided with a test support surface 100a, wherein the test support surface 100a is used to place the multifunctional bare board 2 to be tested, and the RF floating integrated module 200 includes a first elastic RF connector 210, a second elastic RF connector 220, a first straight-through interconnection connector 230 and a second straight-through interconnection connector 240, wherein the first elastic RF connector 210, the second elastic RF connector 220, the first straight-through interconnection connector 230 and the second straight-through interconnection connector 240 are arranged at intervals on the mounting base 100, and the contact end of the first elastic RF connector 210 protrudes from the test support surface. 100a, the contact end of the first elastic RF connector 210 is used to elastically abut against the first solder pad of the multifunctional bare board 2 to be tested, the contact end of the second elastic RF connector 220 protrudes from the test support surface 100a, and the contact end of the second elastic RF connector 220 is used to elastically abut against the second solder pad of the multifunctional bare board 2 to be tested, the contact end of the first straight-through interconnect connector 230 protrudes from the test support surface 100a, and the contact end of the first straight-through interconnect connector 230 is used to elastically abut against the third solder pad of the multifunctional bare board 2 to be tested, the contact end of the second straight-through interconnect connector 240 protrudes from the test support surface 100a, and the contact end of the second straight-through interconnect connector 240 is used to elastically abut against the fourth solder pad of the multifunctional bare board 2 to be tested.
[0038] In the present embodiment, since the contact ends of the first elastic RF connector 210, the second elastic RF connector 220, the first straight-through interconnection connector 230 and the second straight-through interconnection connector 240 all protrude from the test support surface 100a and elastically abut against the corresponding pads of the multifunctional bare board 2 to be tested, the problems of slight unevenness or installation position deviation of the pads of the multifunctional bare board 2 are effectively avoided, the reliability of the interconnection between each connector and the multifunctional bare board 2 during the test is ensured, the interruption of the test signal due to poor contact is reduced, the accuracy of the test result and the test efficiency are ensured, and since different types of connectors are provided, different signals can be transmitted when the multifunctional bare board 2 to be tested is tested, and the various functions of the multifunctional bare board 2 are tested. Since the interconnection is carried out in an elastic abutment manner rather than a welding manner, the risk of welding contact damage to the multifunctional bare board 2 and each connector during the welding process is avoided.
[0039] It can be understood that, since the RF floating integrated module 200 is arranged on the mounting base 100, wherein the RF floating integrated module 200 includes a first elastic RF connector 210, a second elastic RF connector 220, a first straight interconnection connector 230 and a second straight interconnection connector 240, when it is necessary to test various performances of the multifunctional bare board 2 to be tested, the present disclosure uses the first elastic RF connector 210, the second elastic RF connector 220, the first straight interconnection connector 230 and the second straight interconnection connector 240 to elastically abut against the first pad, the second pad, the third pad and the fourth pad of the multifunctional bare board 2 to be tested, respectively, one by one, thereby improving the reliability of the mutual abutment between the multifunctional bare board 2 and each connector, ensuring the accuracy of the test results, and avoiding the use of welding to connect, thereby improving the convenience of installation of the multifunctional bare board 2, realizing the solder-free interconnection between the multifunctional bare board 2 and each connector, improving the efficiency of the test of the multifunctional bare board 2, and reducing the risk of contact damage to the connector, thereby improving the service life of the test fixture 1.
[0040] It should be noted that, taking the first elastic RF connector 210 as an example, the first elastic RF connector 210 has the performance of self-resetting elasticity. When the first elastic RF connector 210 uses a fur button as an elastically abutted external contact, in order to reduce the contact wear between the fur button and the first pad of the multifunctional bare board 2 to be tested, a protective cap is provided on the contact end of the fur button, and the protective cap is used to abut against the first pad to protect the fur button and the first pad from abutment wear. Among them, the fur button and the protective cap are not limited to the use of the first elastic RF connector 210, and the fur button and the protective cap are existing components, which will not be further described here.
[0041] like Figure 1 , Figure 2 and Figure 4As shown, in one embodiment, the mounting base 100 is further provided with a mounting fixing surface 100b on the side away from the test support surface 100a, and the mounting fixing surface 100b is used to mount and fix the first elastic RF connector 210, the second elastic RF connector 220, the first straight-through interconnection connector 230 and the second straight-through interconnection connector 240. In this embodiment, the mounting fixing surface 100b ensures the firmness of the installation of the first elastic RF connector 210, the second elastic RF connector 220, the first straight-through interconnection connector 230 and the second straight-through interconnection connector 240, and prevents each connector from loosening when it abuts against the bare board to be tested, thereby affecting the test results. In one embodiment, each connector is connected to the mounting fixing surface 100b by fastening bolts, ensuring that each connector can be repaired and replaced in time, ensuring the accuracy of the signal transmitted by each connector, and thus ensuring the accuracy of the various functions of the multifunctional bare board 2.
[0042] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the first elastic RF connector 210 is a QMA wool button RF connector, and the first elastic RF connector 210 is installed in the first RF channel 101 of the mounting base 100, and the openings at both ends of the first RF channel 101 are respectively formed on the test support surface 100a and the mounting and fixing surface 100b, so that the contact end of the first elastic RF connector 210 protrudes from the test support surface 100a, and the signal output end of the first elastic RF connector 210 protrudes from the mounting and fixing surface 100b. In this embodiment, the QMA fur button RF connector refers to a quick-insert push-in RF connector, which ensures the quick connection between the QMA fur button RF connector and the first soldering pad of the multifunctional bare board 2 to be tested, ensures the accuracy of the abutment position, and improves the efficiency of the test. Since the signal output end of the first elastic RF connector 210 protrudes from the mounting and fixing surface 100b, it is ensured that the output signal of the multifunctional bare board 2 to be tested is led out by the QMA fur button RF connector, and the QMA fur button RF connector is used to be electrically connected to an external test instrument (such as a network analyzer), ensuring that the test signal is transmitted to the external test instrument through the QMA fur button RF connector to complete a partial functional test of the multifunctional bare board 2 to be tested.
[0043] Likewise, if Figure 1 , Figure 2 and Figure 4As shown, in one embodiment, the second elastic RF connector 220 is a total port SMP button RF connector, and the second elastic RF connector 220 is installed in the second RF channel 102 of the mounting base 100, and the openings at both ends of the second RF channel 102 are respectively formed on the test support surface 100a and the mounting and fixing surface 100b, so that the contact end of the second elastic RF connector 220 protrudes from the test support surface 100a, and the signal output end of the second elastic RF connector 220 protrudes from the mounting and fixing surface 100b. In this embodiment, the main port SMP hairy button RF connector refers to an ultra-small push-in RF connector. When the multifunctional bare board 2 needs to be frequently replaced for testing or connection adjustment, the main port SMP hairy button RF connector can quickly complete the plug-in and unplug operations, ensure the reliability of the interconnection, and improve the efficiency of testing the multifunctional bare board 2. The main port SMP hairy button RF connector also needs to be electrically connected to an external test instrument (such as a network analyzer), ensuring that the test signal is transmitted to the external test instrument through the main port SMP hairy button RF connector to complete partial functional testing of the multifunctional bare board 2 to be tested.
[0044] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the first through-interconnection connector 230 is a 6mm through-interconnection connector, which is installed in the first through-interconnection channel 103 of the mounting base 100, and the two end openings of the first through-interconnection channel 103 are respectively formed on the test support surface 100a and the mounting fixing surface 100b, so that the contact end of the first through-interconnection connector 230 protrudes from the test support surface 100a, and the signal output end of the first through-interconnection connector 230 protrudes from the mounting fixing surface 100b. In this embodiment, the 6mm through-interconnection connector refers to a 6mm RF coaxial through-connector, which ensures that the 6mm RF coaxial through-connector transmits the test signal of the multifunctional bare board 2 to the external test instrument, thereby ensuring the effective transmission of various test information and the accuracy of the test.
[0045] like Figure 1 , Figure 2 and Figure 4As shown, in one embodiment, the second through-interconnection connector 240 is a 10mm through-interconnection connector, and the second through-interconnection connector 240 is installed in the second through-interconnection channel 104 of the mounting base 100, and the two end openings of the second through-interconnection channel 104 are respectively formed on the test support surface 100a and the mounting fixing surface 100b, so that the contact end of the second through-interconnection connector 240 protrudes from the test support surface 100a, and the signal output end of the second through-interconnection connector 240 protrudes from the mounting fixing surface 100b. In this embodiment, the 10mm through-interconnection connector refers to a 10mm RF coaxial through-connector, which ensures that the 10mm RF coaxial through-connector transmits the test signal of the multifunctional bare board 2 to the external test instrument, thereby ensuring the effective transmission of various test information and the accuracy of the test.
[0046] It should be noted that in the 6mm RF coaxial straight-through connector and the 10mm RF coaxial straight-through connector, 6mm and 10mm refer to the external length of the connector.
[0047] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the mounting base 100 includes a first grounding base plate 110, a mounting plate 120 and a second grounding base plate 130, the test support surface 100a and the mounting fixing surface 100b are respectively arranged on both sides of the mounting plate 120, one end of the mounting plate 120 is vertically arranged on the first grounding base plate 110, and the second grounding base plate 130 is vertically arranged on the other end of the mounting plate 120, so that the first grounding base plate 110 and the second grounding base plate 130 are parallel to each other; when the first grounding base plate 110 is used to support the mounting plate 120, the mounting plate 120 is perpendicular to the ground, and when the first grounding base plate 110 and the second grounding base plate 130 jointly support the mounting plate 120, the mounting plate 120 is parallel to the ground. In this embodiment, since the first grounding base plate 110 and the second grounding base plate 130 are respectively vertically arranged at both ends of the installation placement plate 120, when the multifunctional bare board 2 to be tested needs to be tested, different methods can be used to place the multifunctional bare board 2 to be tested.
[0048] like Figure 4 and Figure 6 As shown, the first method is to place the first grounding base plate 110 on the ground, and the first grounding base plate 110 is used to support the installation placement plate 120 and the second grounding base plate 130, so that the installation placement plate 120 is perpendicular to the ground; Figure 4 and Figure 7As shown, the second method is to place the first grounding bottom plate 110 and the second grounding bottom plate 130 perpendicular to the ground at the same time to jointly support the mounting plate 120 so that the mounting plate 120 is parallel to the ground.
[0049] It should be noted that the above only provides two different ways to place the multifunctional bare board 2 to be tested, and there are other placement ways, which will not be described one by one here.
[0050] Furthermore, if Figure 4 As shown, in one embodiment, the mounting base 100 further includes a plurality of first reinforcement blocks 140 and a plurality of second reinforcement blocks 150, wherein the first reinforcement blocks 140 and the second reinforcement blocks 150 both have a triangular structure, and the two right-angled sides of each of the first reinforcement blocks 140 are respectively connected to the first grounding bottom plate 110 and the mounting plate 120, and the two right-angled sides of each of the second reinforcement blocks 150 are respectively connected to the second grounding bottom plate 130 and the mounting plate 120. In this embodiment, the additional first reinforcement blocks 140 and the second reinforcement blocks 150, on the one hand, improve the firmness of the connection between the first grounding bottom plate 110 and the mounting plate 120, and the firmness of the connection between the second grounding bottom plate 130 and the mounting plate 120, and on the other hand, strengthen the overall structural support stability, thereby ensuring the formation of a mounting base 100 with support strength, thereby ensuring the stability during the performance test of the multifunctional bare board 2.
[0051] like Figure 1 and Figure 5 As shown, in one of the embodiments, a wiring clamp 300 is provided on both the first grounding base plate 110 and the second grounding base plate 130. The wiring clamp 300 is used to organize and bundle the external wires when they are connected. On the one hand, it avoids the problem of misplaced external wires, which may lead to wiring errors and affect the test results. On the other hand, it facilitates quick wiring and checking of wiring conditions, thereby improving the efficiency of the test.
[0052] like Figure 1 and Figure 2As shown, in one embodiment, the mounting surface 100b has a rectangular structure, the number of the first elastic RF connectors 210 is multiple, and the multiple first elastic RF connectors 210 are respectively arranged in the length direction of the mounting surface 100b and the width direction of the mounting surface 100b, so that multiple rows of first elastic RF connector groups are formed in the width direction of the mounting surface 100b; the number of the second elastic RF connectors 220 is multiple, and in the width direction of the mounting surface 100b, the multiple second elastic RF connectors 220 are arranged in intervals on the symmetry line of the mounting surface 100b; the number of the first straight-through interconnection connectors 230 is multiple, and in the length direction of the mounting surface 100b, each of the first straight-through interconnection connectors 230 is arranged between two adjacent first elastic RF connectors 210; the number of the second straight-through interconnection connectors 240 is multiple, and in the width direction of the mounting surface 100b, each of the second straight-through interconnection connectors 240 is arranged between two adjacent rows of the first elastic RF connector groups.
[0053] In this embodiment, since a plurality of first elastic RF connectors 210, a plurality of second elastic RF connectors 220, a plurality of first direct interconnection connectors 230 and a plurality of second direct interconnection connectors 240 are arranged on the mounting and fixing surface 100b, and are distributed according to a certain rule, a plurality of independent signal transmission channels are established at the same time. When multiple functional tests are performed on the multifunctional bare board 2 to be tested, it is effectively prevented that only one connector is tested when testing a certain function, and damage to a single connector is avoided, so that the function cannot be tested. Therefore, multiple settings of a connector ensure multiple RF signal processing, thereby greatly improving the efficiency of the test.
[0054] like Figure 1 and Figure 5 As shown, the present disclosure further provides a test fixture 1, comprising a pressing plate 20 and a radio frequency floating integrated button mechanism 10 for multifunctional bare board testing as described in any of the above embodiments, wherein the pressing plate 20 is vertically arranged on the first grounding bottom plate 110, and the pressing plate 20 is detachably connected to the mounting plate 120, and the pressing plate 20 is used to clamp the multifunctional bare board 2 to be tested between the pressing plate 20 and the mounting plate 120. In this embodiment, by setting the pressing plate 20, the situation of unstable interconnection between the multifunctional bare board 2 to be tested and each connector can be effectively prevented, and the multifunctional bare board 2 to be tested is prevented from being exposed to the outside, and the accumulation of dust is reduced, thereby improving the stability of testing the multifunctional bare board 2.
[0055] like Figure 1 , Figure 5 and Figure 8As shown, in one embodiment, a plurality of guide positioning holes 21 are formed on one side of the pressing plate 20 facing the installation plate 120, and a plurality of guide positioning posts 121 are formed on one side of the installation plate 120 facing the pressing plate 20, and the guide positioning posts 121 are arranged one by one in correspondence with the guide positioning holes 21. In this embodiment, the guide positioning holes 21 of the pressing plate 20 are matched with the guide positioning posts 121 of the installation plate 120, ensuring that the guide positioning posts 121 are accurately inserted into the guide positioning holes 21, thereby ensuring the accuracy of the installation positions of the pressing plate 20 and the installation plate 120.
[0056] Furthermore, if Figure 1 , Figure 7 and Figure 8 As shown, in one embodiment, the guiding and positioning column 121 includes a smooth guiding portion 121a and a positioning and fixing portion 121b connected to each other, the smooth guiding portion 121a is in a truncated cone shape, specifically including a large diameter end and a small diameter end, wherein the large diameter end is used to connect with the positioning and fixing portion 121b, and the small diameter end is used to guide the positioning hole 21 to be inserted into and slide toward the positioning and fixing portion 121b, wherein the positioning and fixing portion 121b is in a cylindrical shape, and the truncated cone-shaped smooth guiding portion 121a enables the guiding and positioning hole 21 to more quickly realize the positioning and installation of the pressing plate 20 and the mounting plate 120, and finally enables the guiding and positioning hole 21 of the pressing plate 20 to be stably fixed on the positioning and fixing portion 121b, thereby improving the efficiency of the installation and positioning of the pressing plate 20 on the multifunctional bare board 2 to be tested.
[0057] When the test fixture 1 is testing the multifunctional bare board 2, it is necessary to connect to a power supply. Since the multifunctional bare board 2 to be tested is clamped by the pressing plate 20 and the mounting plate 120, part of the heat generated during the test cannot be effectively dissipated. Although a plurality of heat dissipation holes are directly opened on the pressing plate 20, the heat dissipation holes can ensure the heat dissipation, but when the test fixture 1 is not in use, the plurality of heat dissipation holes are open, resulting in a serious dust accumulation problem inside the test fixture 1, which can easily cause damage to the contact ends of the internal connectors and other components, thereby affecting the service life of the test fixture 1.
[0058] Therefore, if Figure 1 and Figure 5As shown, in one embodiment, a plurality of heat dissipation slots 23 are provided on the pressing plate 20 at intervals, and a closing cover (not shown) is provided corresponding to each heat dissipation slot 23. When the multifunctional bare board 2 needs to be cooled, the closing cover is removed to ensure that the heat generated when the test fixture 1 is working can be dissipated in time; when the test fixture 1 is not in use, the closing cover covers the heat dissipation slots 23 to prevent dust from entering the interior of the test fixture 1. In another embodiment, the test fixture 1 further includes a plurality of hinges (not shown), and each closing cover corresponds to a hinge, wherein the hinge includes a fixed sheet and a movable sheet connected in rotation, wherein the fixed sheet is connected to the side of the pressing plate 20 away from the mounting plate 120, and the movable sheet is connected to the closing cover, so that the closing cover is always connected to the pressing plate 20. When in use, the closing and opening of the heat dissipation slots 23 by the closing cover is controlled by flipping the movable sheet, thereby avoiding the problem of the closing cover being easily lost.
[0059] like Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, the test fixture 1 further includes a plurality of fasteners 30, and a plurality of fixing holes 22 are formed on the outer periphery of the pressing plate 20. The fasteners 30 are arranged in a one-to-one correspondence with the fixing holes 22, and the fasteners 30 are installed on the mounting plate 120 through the fixing holes 22. In this embodiment, the plurality of fasteners 30 ensures the firmness of the connection between the pressing plate 20 and the mounting plate 120, ensures the firmness of the multifunctional bare board 2 clamped between the pressing plate 20 and the mounting plate 120, avoids the position of the multifunctional bare board 2 from being offset, and thus improves the accuracy of the test of the multifunctional bare board 2.
[0060] When testing the multifunctional bare board 2, the pressing plate 20 needs to fit the outer surface of the multifunctional bare board 2, so that the pressing plate 20 presses and wears the outer surface of the multifunctional bare board 2, resulting in contact damage to the multifunctional bare board 2, thereby affecting the test performance of the multifunctional bare board 2. In one embodiment, a buffer pad (not shown) is provided on the side of the pressing plate 20 facing the mounting plate 120, and the buffer pad effectively avoids direct contact between the pressing plate 20 and the outer surface of the multifunctional bare board 2, avoids the problem of wear of the multifunctional bare board 2, and ensures gentleness during pressing.
[0061] like Figure 1 , Figure 5 and Figure 7As shown, when testing the multifunctional bare board 2 to be tested, the first grounding bottom plate 110 and the second grounding bottom plate 130 are simultaneously perpendicular to the ground, and jointly support the mounting plate 120, so that the mounting plate 120 is parallel to the ground. The mounting plate 120 is used to place the multifunctional bare board 2 to be tested. This placement method ensures that the multifunctional bare board 2 to be tested and the interconnection with each connector is more stable. However, when the pressing plate 20 is pressed on the multifunctional bare board 2, the weight of the pressing plate 20 itself will be added to the multifunctional bare board 2, so that the multifunctional bare board 2 is crushed. In one embodiment, a plurality of elastic telescopic columns (not shown) are arranged on the side of the mounting plate 120 facing the pressing plate 20, and the plurality of elastic telescopic columns are evenly arranged on the periphery of the mounting plate 120, and the elastic telescopic columns are used to elastically abut the pressing plate 20. In the present embodiment, through the telescopic adjustment of the elastic telescopic column, since the elastic telescopic column has a certain elasticity, when installing the pressure plate 20, the pressure plate 20 first elastically abuts against the elastic telescopic column, and then is slowly pressed down and fitted by the elastic force of the elastic telescopic column, so as to avoid the pressure plate 20 being directly pressed onto the multifunctional bare board 2 for installation. The plurality of elastic telescopic columns ensure that when the pressure plate 20 is pressed onto the multifunctional bare board 2, the elastic telescopic columns play a supporting and buffering role around the pressure plate 20. On the one hand, it can ensure that the pressure plate 20 presses the multifunctional bare board 2 to prevent the multifunctional bare board 2 from moving. On the other hand, it can alleviate the pressure plate 20 from directly pressing its own weight on the multifunctional bare board 2 for installation, thereby effectively preventing the multifunctional bare board 2 from being crushed during testing.
[0062] Compared with the prior art, the present invention has at least the following advantages:
[0063] The RF floating integrated button mechanism 10 for multifunctional bare board testing disclosed in the present invention has a RF floating integrated module 200 disposed on the mounting base 100, wherein the RF floating integrated module 200 includes a first elastic RF connector 210, a second elastic RF connector 220, a first straight interconnection connector 230 and a second straight interconnection connector 240. When it is necessary to test various performances of the multifunctional bare board 2 to be tested, the present invention uses the first elastic RF connector 210, the second elastic RF connector 220, the first straight interconnection connector 230 and the second straight interconnection connector 240 to elastically abut against the first pad, the second pad, the third pad and the fourth pad of the multifunctional bare board 2 to be tested, respectively, one by one. This not only improves the reliability of the mutual abutment between the multifunctional bare board 2 and each connector, ensures the accuracy of the test result, but also avoids the use of welding to connect, improves the convenience of installation of the multifunctional bare board 2, realizes the solder-free interconnection between the multifunctional bare board 2 and each connector, improves the efficiency of the test of the multifunctional bare board 2, and reduces the risk of contact damage to the connector, thereby improving the service life of the test fixture 1.
