[0027] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0028] Reference below Figure 1-Figure 6 A radio frequency test module according to an embodiment of the present utility model is described.

[0029] The function of the RF test module is to electrically connect the probe to the test instrument when performing board-level RF performance testing on wireless products. The board is provided with a detection point for the RF chip. By contacting the probe with the detection point of the board, when the RF chip on the board sends or receives an RF signal, the signal will be transmitted through the detection point and the probe to the test instrument for testing the RF signal.

[0030] like Figure 1 As shown, the RF test module includes: a detection component 10, a mounting hole 11 is provided in the detection component 10, the mounting hole 11 passes through the detection component 10 in the height direction, and the probe passes through the mounting hole 11 and selectively abuts against the detection point of the plate. Specifically, the detection component 10 is provided with a mounting hole 11 that passes through the detection component 10 in the height direction, the probe passes through the mounting hole 11, and the probe is fixedly connected to the detection component 10, so the probe moves with the movement of the detection component 10.

[0031] The probe part protrudes from the lower end of the mounting hole 11, so that when the detection component 10 moves downward, the probe first abuts against the detection point on the board. During the test, the detection component 10 is set relative to the detection point, and the detection component 10 moves downward so that the probe abuts against the detection point. When the RF chip on the board sends or receives RF signals, the signal will be transmitted through the detection point and the probe to the test instrument for RF signal testing; after the test is completed, the detection component 10 moves upward, and the probe is separated from the detection point.

[0032] Among them, a first grounding portion 12 is provided on the detection component 10, and the first grounding portion 12 selectively abuts against the second grounding portion on the board to achieve grounding, and the first grounding portion 12 and the mounting hole 11 are arranged at intervals in the horizontal direction. Specifically, the first grounding portion 12 is arranged on the side of the detection component 10 facing the board, that is, the lower side of the detection component 10, and a second grounding portion is provided on the board, and the second grounding portion is a grounding pad. The second grounding portion and the detection point are arranged at intervals on the board, and the first grounding portion 12 is arranged opposite to the second grounding portion, and the first grounding portion 12 and the mounting hole 11 are also arranged at intervals in the horizontal direction, so that the detection component 10 can test non-coaxial test points, and even when the detection point is far away from the grounding pad, the detection component 10 can complete the test of the RF function.

[0033] When testing a certain detection point, the detection component 10 moves downward, and the lower surface of the first grounding part 12 is flush with the lower end of the probe. When the probe abuts the detection point, the first grounding part 12 abuts against the second grounding part. The size of the first grounding part 12 is smaller than the size of the second grounding part, so that the first grounding part 12 is in full contact with the second grounding part to form a loop between the probe and the board, thereby completing the test of the board's radio frequency function.

[0034] Therefore, the mounting hole 11 and the first grounding portion 12 are spaced apart, and the probe passing through the mounting hole 11 can measure the RF function of non-coaxial test points with larger spacing, thereby solving the problem that non-coaxial test points with larger spacing on the board cannot be tested.

[0035] In some embodiments, the detection components 10 are multiple groups, and in the horizontal direction, the distances between the first grounding parts 12 of the multiple detection components 10 and the center of the mounting hole 11 are different. Specifically, multiple detection points and multiple second grounding parts are set on the plate, and any detection point corresponds to a detection component 10. During testing, multiple detection components 10 move downward at the same time, and multiple probes pass through the mounting holes 11 of multiple detection components 10 respectively, and abut against multiple detection points. The first grounding parts 12 on multiple detection components 10 abut against multiple second grounding parts, so that multiple detection components 10 detect the radio frequency functions of multiple detection points.

[0036] The distance between the first grounding portion 12 and the center of the mounting hole 11 in the horizontal direction is L. The Ls of the multiple detection components 10 are different, which can meet the RF function test of non-coaxial test points with larger spacing.

[0037] In some embodiments, the probe includes: a first part and a second part, one end of the second part is connected to the first part and the other end is abutted against the detection point. Specifically, the first part and the second part are both fitted in the mounting hole 11, the first part and the second part are connected, the first part is an annular grounding end, the second part is the probe inner core, the first part and the second part are coaxially designed, one end of the second part is connected to the first part, and the other end of the second part selectively abuts against the detection point. When testing a certain detection point, the detection component 10 moves downward, and when the other end of the second part abuts against the detection point, the first grounding part 12 abuts against the second grounding part to form a loop between the probe and the board, thereby completing the test of the radio frequency function of the board.

[0038] Combination Figure 1-Figure 6 As shown, the mounting hole 11 includes: a first hole portion 111 and a second hole portion 112, the first hole portion 111 is arranged above the second hole portion 112, and the inner diameter of the first hole portion 111 is larger than the inner diameter of the second hole portion 112. Specifically, the first hole portion 111 and the second hole portion 112 are connected and coaxially arranged, the inner diameter of the first hole portion 111 is larger than the inner diameter of the second hole portion 112, and a step portion 113 is formed between the first hole portion 111 and the second hole portion 112, the second portion fits in the second hole portion 112, the first portion fits in the first hole portion 111, and the first portion abuts against the step portion 113. The other end of the second part protrudes from the lower end of the second hole 112. When the detection component 10 moves downward to test the RF function of the detection point, the other end of the second part abuts against the detection point. When the RF chip on the board sends or receives an RF signal, the signal will be transmitted through the detection point and the probe to the test instrument for testing the RF signal. After the test is completed, the detection component 10 moves upward, the other end of the second part is separated from the detection point, and the first grounding part 12 is also separated from the second grounding part.

[0039] In some embodiments, the outer diameter of the first part is A, the outer diameter of the second part is B, the inner diameter of the second hole 112 is C, and A, B and C satisfy the relationship: A>C>B. Specifically, the outer diameter of the second part is smaller than the outer diameter of the first part, and the inner diameter of the second hole 112 is smaller than the outer diameter of the first part and larger than the outer diameter of the second part, so that the first part abuts against the step 113, but the second part can pass through the second hole 112, so that the other end of the second part abuts against the detection point when the detection component 10 moves down, thereby forming a closed loop between the probe, the board and the detection component 10, and when the RF chip on the board sends or receives RF signals, the signal will be transmitted through the detection point and the probe to the test instrument for RF signal testing.

[0040] In some embodiments, an abutment portion is provided on the probe, and the abutment portion is connected to the side of the first part away from the second part, and the abutment portion abuts and is fixedly connected to the upper surface of the detection component 10. Specifically, the abutment portion is located on the side of the first part away from the second part, the abutment portion abuts against the peripheral side of the mounting hole 11, and the abutment portion is fixedly connected to the detection component 10, so that the probe is fixedly connected to the detection component 10, and the probe moves with the movement of the detection component 10. When the board needs to detect the RF function, the detection component 10 moves downward, and the probe is fixed on the detection component 10, then the probe moves downward with the detection component 10 until the other end of the second part abuts against the detection point, and the first grounding portion 12 also abuts against the second grounding portion, forming a closed loop between the probe, the board and the detection component 10. When the RF chip on the board sends or receives RF signals, the signal will be transmitted through the detection point and the probe to the test instrument for RF signal testing.

[0041] like Figure 1 and Figure 5 As shown, the RF test module also includes: a fastener, a first fixing portion is provided on the abutting portion, and the detection component 10 is provided with a second fixing portion 13, and the fastener passes through the first fixing portion and is fixedly connected with the second fixing portion 13.

When the detection component 10 moves downward, the probe abuts against the detection point, and the RF function of the detection point can be tested; after the test is completed, the detection component 10 moves upward, and the probe is separated from the detection point.

[0042] Furthermore, there can be two first fixing parts, two second fixing parts 13, two fasteners, the two first fixing parts and the two second fixing parts 13 are respectively arranged opposite to each other, and the two fasteners respectively pass through the two first fixing parts and are fixedly connected to the two second fixing parts 13, thereby further improving the connection strength between the probe and the detection component 10.

[0043] The fastener may be a screw, the second fixing portion 13 may be a groove with an internal thread, and the external thread of the screw is threadedly connected with the internal thread of the groove.

[0044] like Figure 2 and Figure 6As shown, the first grounding portion 12 is provided with a first groove 121 and a second groove 122 on one side facing the second grounding portion, and the first groove 121 and the second groove 122 are recessed inwardly and staggered with each other. In other words, the first grounding portion 12 is provided with a first groove 121 and a second groove 122, and the first groove 121 and the second groove 122 are recessed inwardly, and the first groove 121 and the second groove 122 are staggered with each other. Such a design divides the lower end of the first grounding portion 12 into a plurality of areas, ensuring that the first grounding portion 12 is in full contact with the second grounding portion, and avoiding insensitive contact when the probe tests the RF function of the detection point.

[0045] Furthermore, the first groove 121 and the second groove 122 may be perpendicular to each other.

[0046] Furthermore, if Figure 6 As shown, there may be a plurality of first grooves 121 , and the plurality of first grooves 121 are parallel to each other; there may be a plurality of second grooves 122 , and the plurality of second grooves 122 are parallel to each other.

[0047] In some embodiments, the RF test module further includes: a driving component, which is in transmission connection with the detection component 10 and is used to drive the detection component 10 to move up and down.

When the panel is tested, the driving component drives the detection component 10 to move downward, and the probe moves downward until it abuts against the detection point, and the first grounding portion 12 on the detection component 10 abuts against the second grounding portion, so that the detection component 10 detects the RF function of the detection point; after the test is completed, the driving component drives the detection component 10 to move upward, and the probe is separated from the detection point.

[0048] In some embodiments, the driving component includes: a driving member and a transmission member, the driving member and the transmission member are transmission-connected, the transmission member is fixedly connected to the detection component 10, and the driving member drives the transmission member to move up and down. Specifically, the transmission member is fixedly connected to the detection component 10, and the driving member drives the transmission member to move up and down, thereby driving the detection component 10 to move up and down. When the panel is tested, the driving member drives the transmission rod to move downward, the detection component 10 moves downward with the transmission member, and the probe moves downward until it abuts against the detection point, and the first grounding portion 12 on the detection component 10 abuts against the second grounding portion, so that the detection component 10 detects the radio frequency function of the detection point; after the test is completed, the driving member drives the transmission member to move upward, the detection component 10 moves upward accordingly, and the probe is separated from the detection point.
