Description

Technical Field

[0001] The present invention relates to the technical field of filter aging, and particularly relates to a filter aging test unit and an aging test device. Background Art

[0002] For an LC filter composed of horizontal pins and a square cavity, due to the material properties of the pins, the pins are extremely easy to bend. The filters with bent pins will affect the clamping progress during the initial clamping process of the aging test, and the aging test has a very long time cycle. When a large number of such filters need to be aged simultaneously, the key to saving the test cycle is to perform the aging test on as many filters simultaneously as possible.

[0003] However, currently, when performing simultaneous aging tests on a large number of filters, the wiring of the aging board is complex, and since the distance between the filters is relatively close, the filters are not easy to move and install, and the pins are easily bent during the moving process. Therefore, how to simplify the wiring on the basis of performing simultaneous aging tests on a large number of filters and avoid the test uncertainties caused by the bending of the filter pins is the key to ensuring the smooth completion of the test and accurate and reliable results. Summary of the Invention

[0004] The purpose of the present invention is to develop a filter aging test unit and an aging test device that keep adjacent filters at a distance and avoid bending of the pins during the process of moving the filters.

[0039] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0040] As Figures 1 - 6 shown, the present invention discloses a filter aging test unit and an aging test device. The filter aging test unit includes a base that can be extended and shortened, and a plurality of test seats 2 are provided on the base. The test seats 2 accommodate filters for testing.

[0041] The base includes two end plates 1 arranged in parallel with each other. Two first telescopic rods 15 are provided between the two end plates 1. The two ends of the two first telescopic rods 15 are respectively connected to the two end plates 1, and the two first telescopic rods 15 are perpendicular to the two end plates 1. The two end plates 1 are slidably guided by the first telescopic rods 15, so that the two end plates 1 slide in a direction perpendicular to them.

[0042] A length-adjustable telescopic rod is also provided between the two end plates 1. The two length-adjustable telescopic rods are parallel to the first telescopic rod 15. The two ends of the two length-adjustable telescopic rods are respectively connected to the two end plates 1. The length-adjustable telescopic rod includes a fixed rod 12 and a rotating rod 11 that are in a coaxial state and are respectively arranged on the two end plates 1. The rotating rod 11 is rotatably arranged on the end plate 1. The fixed rod 12 is a threaded rod, and a threaded hole that is in threaded cooperation with the fixed rod 12 is provided on the rotating rod 11. When the rotating rod 11 rotates, under the threaded cooperation between the threaded hole and the fixed rod 12, the rotating rod 11 slides on the fixed rod 12, thereby changing the distance between the two end plates 1.

[0043] First bevel gears 13 are coaxially provided on the rotating rods 11 of the two length-adjustable telescopic rods. A first transmission rod 18 is rotatably provided between the two first bevel gears 13. The first transmission rod 18 is perpendicular to the two rotating rods 11.

A support 17 that is rotatably connected to the first transmission rod 18 is provided at the end of the support rod 16. By means of the support rod 16 and the support 17, the position of the first transmission rod 18 is fixed. The second bevel gears 14 at the two ends of the first transmission rod 18 are respectively meshed with the two first bevel gears 13, so that the two rotating rods 11 rotate synchronously, and the two length-adjustable telescopic rods expand and contract synchronously.

[0044] A scissor assembly 19 is provided between the two end plates 1. The two ends of the scissor assembly 19 are respectively slidably connected to the two end plates 1. When the distance between the two end plates 1 changes, the scissor assembly 19 expands and contracts correspondingly. The scissor assembly 19 includes a plurality of scissor rods that are rotatably connected end to end in two columns. The middle parts of the two columns of scissor rods are sequentially hinged. First sliding seats are respectively rotatably provided at the end parts of the two scissor rods at the two ends of the scissor assembly 19. First sliding rails that are slidably connected to the first sliding seats are respectively provided at the corresponding positions on the two end plates 1. The first sliding rails are perpendicular to the first telescopic rod 15. When the distance between the two end plates 1 changes to make the scissor assembly 19 expand and contract, the first sliding seats at the two ends of the scissor assembly 19 approach or move away from each other on the first sliding rails.

[0045] In the scissor assembly 19, a test seat 2 is provided above the hinge at the middle part of the two scissor rods. The bottom of the test seat 2 is connected to the pin shaft 20 at the hinge at the middle part of the scissor rod. During the expansion and contraction process of the scissor assembly 19, the pin shafts 20 at the middle parts of the plurality of scissor rods change the distance, and the plurality of pin shafts 20 maintain an equal distance during the process of changing the distance. Through the connection with the pin shaft 20, the test seat 2 can also maintain an equal distance while changing the distance.

[0046] The test socket 2 is provided with a strip-shaped groove 3, and the length direction of the groove 3 is perpendicular to the telescopic direction of the scissor assembly 19. On the test socket 2 at one end of the groove 3, a left baffle 5 is provided. The left baffle 5 is provided with a slot for mating with the pins of the filter. The slot is in the middle in the width direction of the groove 3. On the side wall of the left baffle 5 away from the groove 3, an SMA connector 4 for mating with the slot is provided.

[0047] On the test socket 2 above the groove 3, a right baffle 6 is slidably provided. On the test socket 2 on both sides of the length direction of the groove 3, second slide rails 21 are respectively provided. The second slide rails 21 are parallel to the length direction of the groove 3. On both sides of the bottom of the right baffle 6, second slide seats for slidably connecting with the second slide rails 21 are respectively provided. At the corresponding positions on the right baffle 6, slots are provided. These slots are also in the middle in the width direction of the groove 3. On the side wall of the right baffle 6 away from the left baffle 5, an SMA connector 4 for mating with the slot is also provided.

[0048] The filter is placed in the groove 3, and the pins at both ends of the filter are respectively inserted into the slots and the SMA connectors 4 on the left baffle 5 and the right baffle 6.

[0049] On the tops of both end plates 1, third slide rails are respectively provided. The third slide rails are arranged parallel to the second slide rails 21. On the third slide rails, third slide seats 8 are slidably provided. On the top of the end plate 1 on the side of the third slide rail away from the left baffle 5, a fixed seat 10 is provided. Between the fixed seat 10 and the third slide seat 8, a spring telescopic rod 9 is provided. The spring telescopic rod 9 is arranged parallel to the third slide rail. Under the elastic force of the spring telescopic rod 9, the third slide seat 8 is elastically pushed towards one end of the third slide rail close to the left baffle 5.

[0050] Second telescopic rods 7 are provided between the right baffles 6 on adjacent two test sockets 2 and between the third slide seat 8 and the right baffle 6 on its side. The second telescopic rods 7 are perpendicular to the sliding directions of the third slide seat 8 and the right baffle 6. The provided multiple second telescopic rods 7 enable the two third slide seats 8 and the multiple right baffles 6 to slide synchronously along the length direction of the groove 3. Through the transmission of the elastic force of the spring telescopic rod 9 by the multiple second telescopic rods 7, the multiple right baffles 6 slide towards the left baffle 5 on the test socket 2. Moreover, the provided second telescopic rods 7 also prevent the test socket 2 from rotating around its connection with the scissor assembly 19.

[0051] A plurality of clamping components are provided in the groove 3 in its length direction. The clamping components include sliding grooves 26 provided on both side walls of the groove 3, and the sliding grooves 26 are arranged along the width direction of the groove 3. A fourth sliding seat 31 is slidably provided in the sliding groove 26, and a fourth sliding rail 27 slidably connected to the fourth sliding seat 31 is provided at the bottom of the sliding groove 26. The fourth sliding rail 27 is arranged along the width direction of the groove 3, so that the fourth sliding seat 31 slides along a direction perpendicular to the length direction of the groove 3. In the same clamping component, clamping blocks 22 are respectively provided on the side walls of the two fourth sliding seats 31 close to each other. The upper side walls of the two clamping blocks 22 close to each other are of an inclined surface structure, and the upper part of this inclined surface structure tends to incline towards the inner side of the sliding groove 26. When the fourth sliding seat 31 slides to the outer end in the sliding groove 26, the top end of this inclined surface structure is coplanar with the inner wall of the groove 3.

[0052] In the clamping component, a rotating column 23 is rotatably provided in the test seat 2 below the middle of the two clamping blocks 22. A torsion spring is provided between the rotating column 23 and the test seat 2, and the elastic force of the torsion spring drives the rotating column 23 to rotate. Two second transmission rods 24 are provided on the rotating column 23, and the two second transmission rods 24 are on the same radial direction of the rotating column 23. A third transmission rod 25 is hinged to the free end of the second transmission rod 24, and a push rod 29 is provided at the free end of the third transmission rod 25. The push rod 29 is arranged vertically. A guiding groove 28 is provided on the test seat 2 at the bottom of the groove 3. The top end of the push rod 29 passes through the guiding groove 28 and is between the bottom of the groove 3 and the bottom of the clamping block 22. The guiding groove 28 is arranged along the radial direction of the rotating column 23 and the width direction of the groove 3. A pushing block 30 rotatably connected to the top end of the push rod 29 is provided on the fourth sliding seat 31 below the clamping block 22, and the rotating shaft between the push rod 29 and the pushing block 30 is vertical. Under the elastic force of the torsion spring, the rotating column 23 rotates, the included angles between the two second transmission rods 24 and the length direction of the groove 3 decrease, the second transmission rods 24 swing to drive the third transmission rods 25 to swing, the third transmission rods 25 pull the push rod 29, so that the push rod 29 slides in the guiding groove 28 towards the direction of the rotating column 23, the push rod 29 pulls the pushing block 30 to make the fourth sliding seat 31 slide towards the direction of the rotating column 23, and the fourth sliding seat 31 is at the outermost end on the fourth sliding rail 27.

[0053] Filters of different sizes can be accommodated in the groove 3 of the test seat 2. The width of the filter does not exceed the width of the groove 3 and is not less than the minimum distance between the two clamping blocks 22. When the filter is placed in the test seat 2, the filter acts on the inclined surface structure of the clamping block 22, so that the clamping block 22 slides into the sliding groove 26. The elastic force of the torsion spring finally makes the clamping block 22 clamp both sides of the filter, fix the filter, and make the filter in the middle of the width direction of the groove 3.

[0054] The filter aging test device includes six filter aging test units and two power dividers 32. The six filter aging test units are arranged in a 2×3 (2 rows and 3 columns) matrix, and the two power dividers 32 are respectively arranged on both sides of the matrix. The SMA connectors 4 of the adjacent filter aging test units on the left and right are electrically connected through a flexible cable 33. The two power dividers 32 are respectively electrically connected to the SMA connectors 4 of the filter aging test units on the two outer sides through a flexible cable 33. According to the size of the filter to be tested, rotate the rotating rod 11 of the length adjustment telescopic rod to make the distance between the plurality of test seats 2 adapt to the size of the filter. When the filter is larger, increase the distance between the test seats 2; when the filter is smaller, the distance between the test seats 2 can be reduced. By changing the distance between the test seats 2, while making the size of the filter aging test unit as small as possible, a suitable distance is maintained between the filters on the adjacent test seats 2, and the side filters are not accidentally touched when the filter is moved, thus avoiding the bending of its pins.

[0055] The present invention has the following beneficial effects:

[0056] The test seat 2 in the filter aging test unit can accommodate filters of different sizes. When the size of the filter is smaller than the groove 3 of the test seat 2, the clamping assembly arranged in the groove 3 clamps and fixes the filter while making the filter centered in the groove 3, so that the pins of the filter are adapted to the SMA connector 4 in position;

[0057] The size of the filter aging test unit can be adjusted by the length adjustment telescopic rod, so that while ensuring a certain distance between adjacent filters, the size of the filter aging test unit is minimized as much as possible, so as to maximize the number of filter aging test units arranged in a limited space, increase the number of filters tested as much as possible, make the distance between filters suitable according to the size of the filter, facilitate the loading and unloading of the filters on the test unit, improve the loading and unloading efficiency, and avoid the bending of the pins of the filter as much as possible during the loading and unloading process;

[0058] The multiple filter aging test units are connected by a flexible cable 33, avoiding intricate wiring and realizing the simplification of line connection. The use of the power divider 32 simplifies the complexity, reduces the interfaces of the aging box body, reduces the number of cable connections between the box body and the filter aging test units. The adjacent filter aging test units are connected, increasing the number of tests in a single aging test, improving the work efficiency and shortening the work cycle.

[0059] The above embodiments are only the preferred embodiments of the present invention, and do not limit the technical solutions of the present invention.
