[0040] It should be noted that, taking the first elastic radio frequency connector 210 as an example, the first elastic radio frequency connector 210 has the self-resetting elastic performance, when the first elastic radio frequency connector 210 adopts the snap button as the external contact piece for elastic abutment, in order to reduce the contact wear between the snap button and the first pad of the multifunctional bare board 2 to be tested, the protective cap is arranged on the contact end of the snap button, the protective cap is used for abutting the first pad, and the protective cap plays a role in protecting the abutment wear of the snap button and the first pad. The snap button and the protective cap are not limited to the use of the first elastic radio frequency connector 210, and the snap button and the protective cap are existing elements, which will not be described further.

[0041] As Figure 1 , Figure 2 and Figure 4As shown in the drawings, 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, which is used to mount and fix the first elastic radio frequency connector 210, the second elastic radio frequency connector 220, the first straight-through interconnection connector 230 and the second straight-through interconnection connector 240.

In one embodiment, the connectors are connected to the mounting fixing surface 100b by fastening bolts, ensuring that the connectors can be timely repaired and replaced, ensuring the accuracy of the signal transmission of the connectors, thereby ensuring the accuracy of the functions of the multifunctional bare board 2.

[0042] Specifically, as shown in the drawings, Figure 1 , Figure 2 and Figure 4 , in one embodiment, the first elastic radio frequency connector 210 is a QMA Velcro radio frequency connector, which is mounted in the first radio frequency channel 101 of the mounting base 100, and the two ends of the first radio frequency channel 101 are respectively formed with openings on the test support surface 100a and the mounting fixing surface 100b, so that the contact end of the first elastic radio frequency connector 210 protrudes from the test support surface 100a, and the signal output end of the first elastic radio frequency connector 210 protrudes from the mounting fixing surface 100b.

[0043] Similarly, as shown in the drawings, Figure 1 , Figure 2 and Figure 4As shown in the drawings, in one embodiment, the second elastic radio frequency connector 220 is a total port SMP push-on radio frequency connector, which is installed in the second radio frequency channel 102 of the mounting base 100, and the two ends of the second radio frequency channel 102 are respectively formed with openings on the test support surface 100a and the mounting fixed surface 100b, so that the contact end of the second elastic radio frequency connector 220 protrudes from the test support surface 100a, and the signal output end of the second elastic radio frequency connector 220 protrudes from the mounting fixed surface 100b. In this embodiment, the total port SMP push-on radio frequency connector refers to a super-small push-in radio frequency connector, which can quickly complete the plugging operation when it is necessary to frequently replace the multifunctional bare board 2 for testing or adjust the connection, ensure the reliability of interconnection, improve the efficiency of testing the multifunctional bare board 2, and the total port SMP push-on radio frequency connector also needs to be electrically connected with the external test instrument (such as a network analyzer), which ensures that the test signal is transmitted to the external test instrument through the total port SMP push-on radio frequency connector to complete the partial function test of the multifunctional bare board 2 to be tested.

[0044] As shown in the drawings, Figure 1 , Figure 2 and Figure 4 , 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 ends of the first through interconnection channel 103 are respectively formed with openings on the test support surface 100a and the mounting fixed 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 fixed surface 100b. In this embodiment, the 6mm through interconnection connector refers to a 6mm radio frequency coaxial through connector, which ensures that the 6mm radio frequency coaxial through connector transmits the test signal of the multifunctional bare board 2 to the external test instrument, ensures the effective transmission of various test information and the accuracy of the test.

[0045] As shown in the drawings, Figure 1 , Figure 2 and Figure 4As shown in the drawings, in one embodiment, the second through interconnection connector 240 is a 10mm through interconnection connector, which is installed in the second through interconnection channel 104 of the mounting base 100, and the two ends of the second through interconnection channel 104 are respectively formed with openings on the test support surface 100a and the mounting fixed 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 fixed surface 100b. In this embodiment, the 10mm through interconnection connector refers to a 10mm radio frequency coaxial through connector, which ensures that the 10mm radio frequency coaxial through connector transmits the test signals of the multifunctional bare board 2 to the external test instrument, and ensures the effective transmission of various test information and the accuracy of the test.

[0046] It should be noted that among the 6mm radio frequency coaxial through connector and the 10mm radio frequency coaxial through connector, 6mm and 10mm refer to the external length of the connector.

[0047] As shown in the drawings, Figure 1 , Figure 3 and Figure 4 , in one embodiment, the mounting base 100 includes a first grounding bottom plate 110, a mounting placement plate 120, and a second grounding bottom plate 130, the test support surface 100a and the mounting fixed surface 100b are respectively arranged on both sides of the mounting placement plate 120, one end of the mounting placement plate 120 is vertically arranged on the first grounding bottom plate 110, and the second grounding bottom plate 130 is vertically arranged on the other end of the mounting placement plate 120, so that the first grounding bottom plate 110 and the second grounding bottom plate 130 are parallel to each other; when the first grounding bottom plate 110 is used to support the mounting placement plate 120, the mounting placement plate 120 is perpendicular to the ground, and when the first grounding bottom plate 110 and the second grounding bottom plate 130 jointly support the mounting placement plate 120, the mounting placement plate 120 is parallel to the ground. In this embodiment, since the two ends of the mounting placement plate 120 are respectively vertically arranged with the first grounding bottom plate 110 and the second grounding bottom plate 130, when the multifunctional bare board 2 to be tested needs to be tested, different ways can be used to place the multifunctional bare board 2 to be tested.

[0048] As shown in the drawings, Figure 4 and Figure 6 , the first way is to place the first grounding bottom plate 110 on the ground, and the first grounding bottom plate 110 is used to support the mounting placement plate 120 and the second grounding bottom plate 130, so that the mounting placement plate 120 is perpendicular to the ground; as shown in the drawings, Figure 4 and Figure 7As shown, the second method is to simultaneously place the first grounding base plate 110 and the second grounding base plate 130 perpendicular to the ground, 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 bare multifunctional board 2 under test. There are other placement methods, which will not be described in detail here.

[0050] Furthermore, such as Figure 4 As shown, in one embodiment, the mounting base 100 further includes a plurality of first reinforcing blocks 140 and a plurality of second reinforcing blocks 150. Each of the first reinforcing blocks 140 and the second reinforcing blocks 150 has a triangular structure. The two right-angled sides of each first reinforcing block 140 are respectively connected to the first grounding base plate 110 and the mounting plate 120, and the two right-angled sides of each second reinforcing block 150 are respectively connected to the second grounding base plate 130 and the mounting plate 120. In this embodiment, the added first reinforcing blocks 140 and second reinforcing blocks 150 improve the robustness of the connection between the first grounding base plate 110 and the mounting plate 120, and the robustness of the connection between the second grounding base plate 130 and the mounting plate 120. Furthermore, they enhance the overall structural support stability, ensuring the formation of a mounting base 100 with sufficient support strength, thereby ensuring stability during performance testing of the multifunctional bare board 2.

[0051] like Figure 1 and Figure 5 As shown, in one embodiment, 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 messy placement of 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 testing.

[0052] like Figure 1 and Figure 2As shown, in one of the embodiments, the mounting surface 100b has a rectangular structure, the number of the first elastic radio frequency connectors 210 is multiple, multiple first elastic radio frequency connectors 210 are respectively arranged along the length direction of the mounting surface 100b and the width direction of the mounting surface 100b, so that multiple rows of first elastic radio frequency connector groups are formed in the width direction of the mounting surface 100b; the number of the second elastic radio frequency connectors 220 is multiple, multiple second elastic radio frequency connectors 220 are arranged on the symmetry line of the mounting surface 100b in the width direction of the mounting surface 100b; the number of the first straight-through interconnection connectors 230 is multiple, each first straight-through interconnection connector 230 is arranged between two adjacent first elastic radio frequency connectors 210 in the length direction of the mounting surface 100b; the number of the second straight-through interconnection connectors 240 is multiple, each second straight-through interconnection connector 240 is arranged between two adjacent rows of first elastic radio frequency connector groups in the width direction of the mounting surface 100b.

[0053] In the embodiment, since multiple first elastic radio frequency connectors 210, multiple second elastic radio frequency connectors 220, multiple first straight-through interconnection connectors 230 and multiple second straight-through interconnection connectors 240 are arranged on the mounting surface 100b and are distributed according to a certain rule, multiple independent signal transmission channels are established at the same time, when multiple functions of the multifunction bare board 2 under test are tested, it is effectively prevented that only one connector is used for testing when a function is tested, and the single connector is damaged and the function cannot be tested. Therefore, multiple connectors are arranged, multiple radio frequency signals are processed, and the testing efficiency is greatly improved.

[0054] As shown in Figure 1 , Figure 5 The present disclosure also provides a test fixture 1, which comprises a pressing plate 20 and the radio frequency floating integrated button mechanism 10 for testing a multifunction bare board according to any one of the embodiments, 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 for clamping the multifunction bare board 2 under test between the pressing plate 20 and the mounting plate 120. In the embodiment, through the arrangement of the pressing plate 20, the instability of the interconnection between the multifunction bare board 2 under test and each connector can be effectively prevented, and the multifunction bare board 2 under test is prevented from being exposed to the outside, and the accumulation of dust is reduced, so that the stability of the multifunction bare board 2 under test is improved.

[0055] As shown in Figure 1 , Figure 5 , Figure 8As shown in the drawings, in one embodiment, the pressing plate 20 is formed with a plurality of guide positioning holes 21 on one side thereof facing the mounting placement plate 120, and the mounting placement plate 120 is formed with a plurality of guide positioning columns 121 on one side thereof facing the pressing plate 20, and the guide positioning columns 121 are arranged one-to-one corresponding to the guide positioning holes 21. In this embodiment, the guide positioning holes 21 of the pressing plate 20 are adapted to the guide positioning columns 121 of the mounting placement plate 120, so that the guide positioning columns 121 are accurately inserted into the guide positioning holes 21, and the accuracy of the mounting position of the pressing plate 20 and the mounting placement plate 120 is ensured.

[0056] Further, as shown in the drawings, Figure 1 , Figure 7 and Figure 8 in one embodiment, the guide positioning column 121 comprises a smooth guide portion 121a and a positioning fixing portion 121b connected together, the smooth guide portion 121a is in the shape of a circular truncated cone, and specifically comprises a large-diameter end and a small-diameter end, wherein the large-diameter end is used to connect with the positioning fixing portion 121b, and the small-diameter end is used to guide the positioning hole 21 to slide into the positioning fixing portion 121b, wherein the positioning fixing portion 121b is in the shape of a cylinder, and the smooth guide portion 121a in the shape of a circular truncated cone makes the positioning hole 21 more quickly realize the positioning and mounting of the pressing plate 20 and the mounting placement plate 120, and finally makes the positioning hole 21 of the pressing plate 20 stably fixed on the positioning fixing portion 121b, and improves the efficiency of the mounting and positioning of the pressing plate 20 to the multifunctional bare board 2 to be tested.

[0057] When the test fixture 1 tests the multifunctional bare board 2, it needs to be connected to a power supply. Since the multifunctional bare board 2 to be tested is clamped by the pressing plate 20 and the mounting placement plate 120, part of the heat generated during the test cannot be effectively dissipated. As for directly opening a plurality of heat dissipation holes on the pressing plate 20, although the opened heat dissipation holes can ensure heat dissipation, when the test fixture 1 is not in use, the opened plurality of heat dissipation holes are open, which causes the problem of serious dust accumulation inside the test fixture 1, which is easy to cause damage to the contact end of the internal connector and other elements, thereby affecting the service life of the test fixture 1.

[0058] Therefore, as shown in the drawings, Figure 1 and Figure 5As shown in the drawings, in one embodiment, a plurality of heat dissipation slots 23 are provided on the pressing plate 20, and each heat dissipation slot 23 is provided with a cover (not shown). When the multifunctional bare board 2 needs to be cooled, the cover is removed to ensure that the heat generated during the operation of the test fixture 1 can be dissipated in time. When the test fixture 1 is not used, the cover covers the heat dissipation slot 23 to prevent dust from entering the inside of the test fixture 1. In another embodiment, the test fixture 1 further comprises a plurality of folding hinges (not shown), and each cover is provided with a folding hinge. The folding hinge comprises a fixed piece and a movable piece connected by rotation. The fixed piece is connected to the side of the pressing plate 20 away from the mounting plate 120, and the movable piece is connected to the cover. The cover is always connected to the pressing plate 20. When in use, the cover is opened and closed by rotating the movable piece, thereby avoiding the problem that the cover is easily lost.

[0059] As shown in the drawings, Figure 5 , Figure 7 and Figure 8 , in one embodiment, the test fixture 1 further comprises a plurality of fasteners 30, and the outer periphery of the pressing plate 20 is provided with a plurality of fixing holes 22. The fastener 30 is provided one-to-one with the fixing hole 22, and the fastener 30 is installed on the mounting plate 120 through the fixing hole 22. In this embodiment, the plurality of fasteners 30 ensure the firmness of the connection between the pressing plate 20 and the mounting plate 120, and ensure the firmness of the clamping of the multifunctional bare board 2 between the pressing plate 20 and the mounting plate 120, thereby avoiding the position of the multifunctional bare board 2 from being deviated, and improving the accuracy of the test of the multifunctional bare board 2.

[0060] When the multifunctional bare board 2 is tested, the pressing plate 20 needs to be attached to the outer surface of the multifunctional bare board 2 to be tested, so that the pressing plate 20 is pressed and worn on the outer surface of the multifunctional bare board 2, which causes the multifunctional bare board 2 to be damaged, 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. The buffer pad effectively avoids the 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 the gentleness during pressing.

[0061] As shown in the drawings, Figure 1 , Figure 5 and Figure 7As shown, when the multifunctional bare board 2 under test is tested, when the first grounding bottom plate 110 and the second grounding bottom plate 130 are vertically arranged on the ground at the same time, the mounting and placing plate 120 is supported together, so that the mounting and placing plate 120 is parallel to the ground, and the mounting and placing plate 120 is used for placing the multifunctional bare board 2 under test. This placement mode ensures that the multifunctional bare board 2 under test and each connector are more stable in interconnection. However, when the pressing plate 20 is pressed on the multifunctional bare board 2, the weight of the pressing plate 20 will be added to the multifunctional bare board 2, so that the multifunctional bare board 2 is pressed. In one embodiment, a plurality of elastic telescopic columns (not shown in the figure) are arranged on the side of the mounting and placing plate 120 facing the pressing plate 20. The plurality of elastic telescopic columns are uniformly arranged on the periphery of the mounting and placing plate 120. The elastic telescopic columns are used for elastically abutting against the pressing plate 20. In this embodiment, the elastic telescopic columns are adjusted by telescopic adjustment. Since the elastic telescopic columns have a certain elasticity, when the pressing plate 20 is mounted, the pressing plate 20 is first elastically abutted against the elastic telescopic columns, and then slowly pressed and fitted by the elastic force of the elastic telescopic columns, so as to avoid that the pressing plate 20 is directly pressed on the multifunctional bare board 2 for mounting. The plurality of elastic telescopic columns ensure that when the pressing plate 20 is pressed on the multifunctional bare board 2, the elastic telescopic columns play a supporting and buffering role around the pressing plate 20. On the one hand, the pressing plate 20 can be guaranteed to press the multifunctional bare board 2, so as to prevent the multifunctional bare board 2 from moving. On the other hand, the pressing plate 20 can be directly pressed on the multifunctional bare board 2 for mounting, so as to effectively prevent the multifunctional bare board 2 from being pressed during testing.

[0062] Compared with the prior art, the present disclosure has at least the following advantages:

[0063] The radio frequency floating integrated button mechanism 10 for testing the multifunctional bare board of the present disclosure is arranged on the mounting base 100. The radio frequency floating integrated module 200 includes the first elastic radio frequency connector 210, the second elastic radio frequency connector 220, the first straight-through interconnection connector 230, and the second straight-through interconnection connector 240. When the performance of the multifunctional bare board 2 under test needs to be tested, the first elastic radio frequency connector 210, the second elastic radio frequency connector 220, the first straight-through interconnection connector 230, and the second straight-through interconnection connector 240 are respectively and correspondingly elastically abutted against the first pad, the second pad, the third pad, and the fourth pad of the multifunctional bare board 2 under test. This not only improves the reliability of the mutual abutment of the multifunctional bare board 2 and each connector, ensures the accuracy of the test result, but also avoids the welding connection mode, improves the convenience of the installation of the multifunctional bare board 2, realizes the welding-free interconnection of the multifunctional bare board 2 and each connector, improves the efficiency of the test of the multifunctional bare board 2, reduces the risk of contact damage of the connector, and prolongs the service life of the test fixture 1.
