Description

Technical Field

[0001] This utility model relates to the field of filter testing, and in particular to a novel handheld filter testing device. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out specific frequencies or frequencies outside of a power supply line to obtain a power signal of a specific frequency, or eliminate a power signal of a specific frequency.

[0003] Chinese patent CN220455447U discloses a buffer-type filter performance testing fixture, in which the RF connector is longitudinally positioned at the bottom of the base. However, when the filter is small, less than the minimum distance that can be set between the ports of the two RF connectors, the filter testing function cannot be achieved. Furthermore, when using a flip-type pressing structure, the distance between the limiting block and the filter cannot be accurately observed in a timely manner, potentially damaging the filter. Additionally, the fixed structure of the limiting block makes it unsuitable for testing filters of different sizes.

[0004] In summary, existing filter testing devices cannot detect small-sized filters, nor can they provide timely and accurate visualization of the structure of down-voltage filters. Utility Model Content

[0005] This utility model overcomes the shortcomings of existing filter testing devices, such as the inability to detect small-sized filters and the inability to accurately and timely observe the structure of down-pressure filters. It provides a novel handheld filter testing device. To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel handheld filter testing device, comprising: a base, a testing component disposed on the base, and a down-pressure component.

[0006] The test assembly includes a test board, test slots on the test board, I / O pins on the test slots, and two RF connectors; the RF connectors are arranged horizontally.

[0007] The pressing assembly includes a fixed column disposed on the base, a pressure handle fixed to the side wall of the fixed column, a pressure rod disposed below the pressure handle, and a pressure head disposed at the bottom of the pressure rod;

[0008] The pressure bar, the pressure head, and the test groove are located on the same straight line;

[0009] When the pressure handle is pressed down, the pressure rod moves downward and the pressure head moves closer to the test slot; when the pressure handle is lifted up, the pressure rod moves upward and the pressure head moves away from the test slot.

[0010] In a preferred embodiment of this utility model, a fixing plate is provided on the side wall of the fixing column. The fixing plate includes an integrally formed pressure plate, a fixing plate, and a connecting plate. The pressure plate is parallel to the test groove, the fixing plate is parallel to the side wall of the fixing column, the fixing plate is fixedly mounted on the side wall of the fixing plate by bolts, and the connecting plate is perpendicular to the fixing plate.

[0011] In a preferred embodiment of this utility model, the pressure plate is provided with a through hole for the pressure rod to pass through, the top of the pressure rod is located above the pressure plate, and the bottom of the pressure rod is located below the pressure plate.

[0012] In a preferred embodiment of this utility model, a guide tube is fixedly provided below the through hole, and the pressure rod is at least partially located inside the guide tube.

[0013] In a preferred embodiment of the present invention, the pressure handle includes a handle and a connecting section, the connecting section being hinged to the connecting plate.

Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0032] like Figure 1 As shown, a handheld novel filter 1 testing device includes: a base 10, a testing component disposed on the base 10, and a pressing component.

[0033] The test assembly includes a test board 201, test slots on the test board 201, I / O pins (not shown) on the test slots, and two RF connectors 202, which are arranged laterally. The test slot includes a first sidewall 2031 and a second sidewall 2032 opposite to the first sidewall 2031. One RF connector 202 passes through the first sidewall 2031, and the other RF connector 202 passes through the second sidewall 2032. The RF connectors 202 are fixed to the test board 201 by bolts.

[0034] Specifically, by horizontally positioning the two RF connectors 202 on the test board 201, the test distance (i.e. the size of the filter 1) is no longer limited by the distance of the RF connectors 202, and filters 1 of any size can be tested.

[0035] The pressing assembly includes a fixed post 301 disposed on the base 10, a pressing handle 302 fixed to the side wall of the fixed post 301, a pressing rod 303 disposed below the pressing handle 302, and a pressing head 304 disposed at the bottom of the pressing rod 303.

[0036] The bottom of the pressure rod 303 is provided with a threaded hole, and the top of the pressure head 304 is provided with a threaded rod. The pressure head 304 is threadedly connected to the pressure rod 303. Here, the position of the pressure head 304 can be adjusted by using the threaded connection structure to adapt to filters 1 of different heights.

[0037] The side wall of the fixed column 301 is provided with a fixing piece 307, which, in conjunction with... Figure 1 and Figure 2 As shown, the fixing plate 307 includes an integrally formed pressure plate 3071, a fixing plate 3072, and a connecting plate 3073. The pressure plate 3071 is parallel to the test groove, the fixing plate 3072 is parallel to the side wall of the fixing column 301, the fixing plate 3072 is fixedly mounted on the side wall of the fixing plate 3072 by bolts, and the connecting plate 3073 is perpendicular to the fixing plate 3072.

[0038] Here, the pressure plate 3071 is placed along the horizontal plane, and the fixing plate 3072 and the connecting plate 3073 are placed along the vertical plane. The pressure plate 3071, the fixing plate 3072, and the connecting plate 3073 are perpendicular to each other.

[0039] Preferably, the pressure plate 3071 has a through hole for the pressure rod 303 to pass through. The top of the pressure rod 303 is located above the pressure plate 3071, and the bottom of the pressure rod 303 is located below the pressure plate 3071. A guide tube 305 is fixedly installed below the through hole, and the pressure rod 303 is at least partially located inside the guide tube 305. The pressure rod 303 can move up and down along the guide tube 305 to reduce errors during downward pressure.

[0040] Combination Figure 3As shown, the handle 302 includes a handle 3022 and a connecting section 3021, which is hinged to the connecting plate 3073.

[0041] Specifically, in combination Figures 1-3 As shown, the pressure handle 302 and the pressure rod 303 are connected by a transmission component. The transmission component is an arc-shaped metal sheet. The connecting plate 3073 is provided with a first hinge hole 3061, the connecting section 3021 is provided with a first hinge hole 3061 and a second hinge hole 3062, the top of the transmission component is provided with a second hinge hole 3062, the bottom of the transmission component is provided with a third hinge hole 3063, and the top of the pressure rod 303 is provided with a third hinge hole 3063.

[0042] The connecting plate 3073 and the pressure handle 302 are hinged through two first hinge holes 3061, the pressure handle 302 and the transmission component are hinged through two second hinge holes 3062, and the transmission component and the pressure rod 303 are hinged through two third hinge holes 3063.

[0043] That is, the first hinge hole 3061 of the connecting plate 3073 overlaps with the first hinge hole 3061 of the connecting section 3021, and is connected by hinges, hinge pins, or other components that enable the two to be hinged, thereby achieving the hinge connection between the connecting plate 3073 and the pressure handle 302. Similarly, the pressure handle 302 and the transmission component, and the transmission component and the pressure rod 303 are also hinged in the same way.

[0044] It should also be noted that the connecting segment 3021 can be a single-layer structure or a double-layer structure. In a preferred embodiment of this utility model, as shown... Figure 3 As shown, the connecting segment 3021 has a double-layer structure to enhance the stability of the connection.

[0045] Reference Figure 1 In this invention, when no external force is applied, the pressure rod 303, the pressure head 304, and the test groove are located on the same straight line. When the pressure handle 302 is pressed down, the pressure rod 303 moves downward and the pressure head 304 moves closer to the test groove; when the pressure handle 302 is lifted, the pressure rod 303 moves upward and the pressure head 304 moves away from the test groove.

[0046] This invention horizontally positions the two RF connectors 202, overcoming the size limitations of the filter 1 and enabling testing of small-sized filters 1. Simultaneously, the pressure-down component ensures accurate contact at the contact points, achieving tight contact between the top and bottom when the cover is pressed down. This guarantees product testing while improving grounding performance, resolving testing conditions for filter 1 after shielding is soldered. It enables rapid, batch testing of filter 1 performance, and also meets testing requirements for poor grounding performance and filter 1 performance testing when the shielding is not soldered. The pressure head 304 of the pressure-down component is adjustable, making this testing device suitable for testing filters 1 of any size. The structure is simple, operation is convenient, and testing efficiency is improved.

[0047] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
