Description

Technical Field

[0001] This application relates to the field of electronic component testing technology, and in particular to a device for testing the electrical performance of a filter. Background Technology

[0002] A filter is a common electronic component that filters alternating current in a power supply line into a state close to direct current, enabling electrical appliances to operate stably. To ensure the quality of the filter, an electrical performance testing device is used to test it. Traditional testing devices mainly consist of tooling fixtures, electrical connection equipment, power supply equipment, and analysis equipment. During use, operators need to adjust the tooling fixtures and electrical connection equipment according to the filter specifications to ensure that the filter can be firmly fixed and that the electrical connection equipment can be connected to the filter's test contacts, thus facilitating subsequent testing operations.

[0003] In practical use, since filters of different specifications have different shapes, when it is necessary to test filters of different specifications, it is necessary to readjust the tooling fixtures and electrical equipment to ensure that they are compatible with the filters, which makes the use cumbersome and inconvenient. In this regard, this application proposes an electrical performance testing device for filters, which aims to solve the above-mentioned problems. Summary of the Invention

[0004] This application proposes an electrical performance testing device for filters, which has the advantage of being adaptable to various filters of different specifications, thereby solving the problem of inconvenience caused by the need for specific adjustments to traditional testing devices according to different filter specifications.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An electrical performance testing device for a filter includes a housing. A strip-shaped hole is provided at the top of the housing. Partitions are arranged near the sides of the inner cavity of the housing. A mounting plate is fixedly installed in the inner cavity between the partitions. Limiting slide rails are provided on the front and back sides near the bottom of the mounting plate. A first locking device is movably installed inside the limiting slide rails. A hollow slide rail is provided at the top of the mounting plate. Bypass holes are provided on both sides of the hollow slide rail. A second locking device is movably installed inside the hollow slide rail. Damping slide rods are provided on the outer sides of the partitions near the front and back sides of the housing. A travel device is movably installed on the outer surface of the damping slide rods. A communicating device is fixedly installed at the bottom of the housing. A bottom hole is provided at the bottom of the housing. Second travel holes are provided on the front of the partitions and on both sides of the outer surface of the housing at positions corresponding to the damping slide rods.

[0007] Furthermore, the strip holes are divided into two rows and distributed in a linear array, the limiting slide rails are distributed in a linear array along the extension direction of the mounting plate, the bottom of the limiting slide rails is provided with a through hole, and the second stroke hole cooperates with the stroke device.

[0008] Furthermore, the first locking device includes a telescopic column, with a limit slider fixedly installed at the bottom of the telescopic column. The limit slider is movably installed inside the limit slide rail. When the filter is placed, it contacts the top of the telescopic column and presses down, causing the telescopic column to move in a vertically downward direction.

[0009] Specifically, a pressing rod is fixedly installed at the bottom of the limiting slider, and a first return spring is engaged at the bottom of the limiting slider outside the pressing rod. The first return spring releases the stored elastic force, causing the first locking device used to clamp and fix the filter to move upward.

[0010] Specifically, a locking block is provided on the back of the telescopic column near the top, a connecting shaft is fixedly installed on the front of the telescopic column near the bottom, a clamping rod is movably installed on the connecting shaft, and an installation groove is opened on the front of the telescopic column near the middle, a locking stop rod is movably installed inside the installation groove.

[0011] Specifically, the telescopic column and the clamping rod are connected by a tension spring.

[0012] Specifically, the limiting slider is movably installed inside the limiting slide rail, the position of the pressing rod corresponds to the position of the through hole in the longitudinal direction, and the bottom end of the first reset spring is connected to the bottom of the limiting slide rail.

[0013] Specifically, the clamping rod rotates towards the telescopic column under the elastic force of the tension spring.

[0014] Specifically, the clamping rod is made entirely of a conductor material.

[0015] Furthermore, a first stroke hole is provided on the front of the clamping rod near the middle position. A spring slide rod is fixedly installed inside the first stroke hole. A movable lock is movably installed on the outer surface of the spring slide rod. The top of the clamping rod is bent, and a gasket is provided at one end of the top of the clamping rod.

[0016] Specifically, the movable latch contacts and engages with the locking lever in the initial state.

[0017] Specifically, the pad is made of insulating material, which serves to prevent slippage and provide insulation when it comes into contact with the outer surface of the filter.

[0018] Furthermore, the second locking device includes a sliding rod, with positioning latches provided on both sides near the top of the sliding rod. The positioning latches are distributed in a linear array along the extension direction of the sliding rod. A push rod is fixedly installed at one end of the sliding rod, extending through the partition and the outer shell to the outside of the outer shell. An end seat is fixedly installed at the other end of the sliding rod, penetrating the partition. A second return spring is provided at one end of the end seat, and one end of the second return spring is connected to the inner wall of the outer shell.

[0019] Specifically, the positioning latch and the locking block correspond to each other in the longitudinal direction. During the downward movement of the telescopic column, the locking block and the positioning latch cooperate to lock each other. After locking, the top of the sliding rod is flush with the top of the outer shell. Pushing the push rod will drive the sliding rod to move, causing the positioning latch and the locking block to be misaligned, thereby releasing the locking state.

[0020] Furthermore, the travel device includes a travel rod, with damping sliders fixedly installed at both ends of the travel rod. The damping sliders are movably sleeved with the damping slide rod, and a gripping part is fixedly installed at one end of the damping slider. When the travel device is lifted as a whole, the travel rod will first contact the locking rod in the first locking device in its initial state, and release the locking rod from the locking state of the movable latch. The clamping rod rotates and contacts the outer surface of the travel rod. Then, the travel device continues to be lifted slowly, while the clamping rod slowly rotates towards the telescopic column until the clamping rod contacts the test contact on the filter. At this point, the travel device is stopped, so that the clamping rod can simultaneously contact the travel rod and the test contact on the filter.

[0021] Specifically, pushing the travel device downward causes the travel lever to rotate the clamping lever outward, and causes the locking lever to re-engage and lock in place, thus restoring the device to its initial state, at which point the clamping levers are fully extended.

[0022] Specifically, the gripping part passes through the second stroke hole, and one end of the gripping part is provided with an insertion hole.

[0023] Specifically, the damping slider is affected by resistance as it slides along the damping rod.

[0024] Specifically, during the upward movement of the travel device, the travel rod will contact the locking rod and push the locking rod to move. During the movement of the locking rod, the locking state with the movable latch will be released.

[0025] Specifically, the socket is connected to a power supply device.

[0026] Furthermore, the connecting device includes a bottom compartment, a connecting seat is provided at the bottom of the bottom cavity near both sides, a spring telescopic seat is provided at the bottom cavity near the middle, a connecting plate is fixedly installed on the top of the spring telescopic seat, and a connecting contact is fixedly installed at the bottom of the connecting plate near both ends, the connecting contact corresponding to the slot on the top of the connecting seat.

[0027] The output terminal of the connector is connected to the input terminal of the power supply equipment via a signal connection.

[0028] This application has the following beneficial effects.

[0029] This device can stably clamp and fix filters of various specifications and shapes. No adjustment is required before clamping and fixing. Simply press down the telescopic column when placing the filter, locking the locking rod and the movable latch into a locked state. Simultaneously, the clamping rod closes and clamps the filter. The upward movement of the travel device causes the travel rod to contact the locking rod and the pressing rod in the first locking device, making this part of the clamping rod contact the outer surface of the travel rod. As the travel device continues to move upward, the clamping rod continues to rotate towards the telescopic column until it contacts the filter's test contacts. At this point, the movement of the travel device stops, allowing the travel rod to simultaneously contact both the clamping rod and the filter's test contacts. The power supply contacts of the power supply equipment are then inserted into the socket. Power can then be supplied and tested through the socket, the travel rod, the clamping rod, and the filter's test contacts. Attached Figure Description

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0049] This application provides an electrical performance testing device for a filter. In a specific embodiment, the electrical performance testing device includes a housing 1. A strip-shaped hole 2 is provided on the top of the housing 1. A partition 3 is provided on the inner cavity of the housing 1 near both sides. An installation plate 4 is fixedly installed on the inner cavity of the housing 1 between the partitions 3. A limiting slide rail 5 is provided on the front and back of the installation plate 4 near the bottom. A first locking device 6 is movably installed inside the limiting slide rail 5. A hollow slide rail 7 is provided on the top of the installation plate 4. A bypass hole 8 is provided on both sides of the hollow slide rail 7. A second locking device 9 is movably installed inside the hollow slide rail 7. A damping slide rod 10 is provided on the outer side of the partition 3 near the front and back of the housing 1. A stroke device 11 is movably installed on the outer surface of the damping slide rod 10. A connecting device 12 is fixedly installed on the bottom of the housing 1. A bottom hole 13 is provided on the bottom of the housing 1. A second stroke hole 14 is provided on the front of the partition 3 and on both sides of the outer surface of the housing 1 at positions corresponding to the damping slide rod 10.

[0050] In this embodiment, the strip holes 2 are divided into two rows and distributed in a linear array. The limiting slide rails 5 are distributed in a linear array along the extension direction of the mounting plate 4. The bottom of the limiting slide rails 5 is provided with a through hole 15, and the second stroke hole 14 cooperates with the stroke device 11.

[0051] A filter 16 is placed on the top of the housing 1.

[0052] In this embodiment, the first locking device 6 includes a telescopic column 61, a limiting slider 62 is fixedly installed at the bottom of the telescopic column 61, the limiting slider 62 is movably installed inside the limiting slide rail 5, a pressing rod 63 is fixedly installed at the bottom of the limiting slider 62, a first return spring 64 is engaged at the bottom of the limiting slider 62 outside the pressing rod 63, a locking block 65 is provided on the back of the telescopic column 61 near the top, a connecting shaft 66 is fixedly installed on the front of the telescopic column 61 near the bottom, a clamping rod 67 is movably installed on the connecting shaft 66, and an installation groove 68 is opened on the front of the telescopic column 61 near the middle, a locking abutment 69 is movably installed inside the installation groove 68;

[0053] The telescopic column 61 and the clamping rod 67 are connected by a tension spring 605;

[0054] The limiting slider 62 is movably installed inside the limiting slide rail 5. The position of the pressing rod 63 corresponds to the position of the through hole 15 in the longitudinal direction. The bottom end of the first return spring 64 is connected to the bottom of the limiting slide rail 5.

[0055] The clamping rod 67 rotates towards the telescopic column 61 under the elastic force of the tension spring 605;

[0056] The clamp 67 is made entirely of conductive material.

[0057] In this embodiment, a first stroke hole 601 is provided on the front of the clamping rod 67 near the middle position. A spring slide rod 602 is fixedly installed inside the first stroke hole 601. A movable lock 603 is movably installed on the outer surface of the spring slide rod 602. The top of the clamping rod 67 is bent, and a gasket 604 is provided at one end of the top of the clamping rod 67.

[0058] In its initial state, the active latch 603 contacts and engages with the locking lever 69, locking it in place.

[0059] The gasket 604 is made of insulating material.

[0060] When placing the filter 16, push the push rod 93 and squeeze the second return spring 95, causing the positioning latch 92 and the locking block 65 to be misaligned. Then, the filter 16 contacts the top of the telescopic column 61 and is pressed down. The telescopic column 61 moves vertically downward. During this process, as the stroke device 11 moves upward, the stroke rod 111 contacts the locking abutment rod 69 and pushes the locking abutment rod 69 to move. During the movement of the locking abutment rod 69, the locking state with the movable latch 603 is released. At the same time, the clamping rod 67 rotates towards the telescopic column 61 under the elastic force of the tension spring 605, so that the top of the clamping rod 67 contacts and clamps the outer surface of the filter 16, thereby achieving fixation. This fixing method can achieve a stable fixing effect for filters 16 of various specifications and does not require additional adjustment, thus improving the practicality of the device.

[0061] Because the top of the clamping rod 67 is provided with a pad 604, it plays an anti-slip role when it contacts and grips the outer surface of the filter 16, and also plays an insulating role. This prevents the current from passing through the tip of the clamping rod 67 and breaking through the outer shell of the filter 16 when the travel rod 111 is energized. Furthermore, the clamping rod 67, which is not in contact with the outer shell of the filter 16 and the test contact 17 and is in a relative position, will not make contact with each other because it is blocked by the travel rod 111. This avoids the problem of short circuit and short circuit of the filter 16, and improves the reliability of the device.

[0062] In this embodiment, the second locking device 9 includes a sliding rod 91. Positioning latches 92 are provided on both sides of the sliding rod 91 near the top. The positioning latches 92 are distributed in a linear array along the extension direction of the sliding rod 91. A push rod 93 is fixedly installed at one end of the sliding rod 91. The push rod 93 passes through the partition 3 and the outer shell 1 and extends to the outside of the outer shell 1. An end seat 94 is fixedly installed at the other end of the sliding rod 91. The end seat 94 passes through the partition 3. A second return spring 95 is provided at one end of the end seat 94. One end of the second return spring 95 is connected to the inner wall of the outer shell 1.

[0063] The positioning latch 92 and the locking block 65 correspond to each other in the longitudinal direction. During the downward movement of the telescopic column 61, the locking block 65 and the positioning latch 92 cooperate to lock, and after locking, the top of the sliding rod 91 remains flush with the top of the outer shell 1.

[0064] When the telescopic column 61 moves down and its top is flush with the top of the housing 1, the locking block 65 and the positioning latch 92 remain locked to prevent the spring force of the first return spring 64 from lifting the filter 16 and causing instability, while keeping the part of the top of the housing 1 that contacts the filter 16 flush.

[0065] In this embodiment, the stroke device 11 includes a stroke rod 111, and damping sliders 112 are fixedly installed at both ends of the stroke rod 111. The damping sliders 112 are movably sleeved with the damping slide rod 10. A gripping part 113 is fixedly installed at one end of the damping slider 112. The gripping part 113 passes through the second stroke hole 14, and an insertion hole 114 is provided at one end of the gripping part 113.

[0066] The damping slider 112 will be affected by resistance during the sliding process along the damping slider 10;

[0067] During the upward movement of the travel device 11, the travel rod 111 will contact the locking rod 69 and push the locking rod 69 to move. During the movement of the locking rod 69, the locking state with the movable latch 603 is released.

[0068] Socket 114 is connected to the power supply equipment.

[0069] Once the device clamps and secures the filter 16, only the first locking device 6 in contact with the filter 16 is triggered and clamps the filter 16, while the other first locking devices 6 remain in their initial state. At this time, the operator can slowly lift the entire travel device 11 by holding the grip part 113. During this process, the travel rod 111 will first contact the locking stop 69 in the first locking device 6 in its initial state, and release the locking stop 69 from the movable latch 603. The clamping rod 67 will rotate and contact the outer surface of the travel rod 111, and then continue... Slowly lift the travel device 11 while simultaneously rotating the clamping rod 67 towards the telescopic column 61 until the clamping rod 67 contacts the test contact 17 on the filter 16. At this point, stop moving the travel device 11 so that the clamping rod 67 can simultaneously contact the travel rod 111 and the test contact 17 on the filter 16. Then, insert the power supply plug into the socket 114 to enable power supply and testing of the test contact 17 of the filter 16 through the travel rod 111 and the clamping rod 67. This testing method can automatically adapt the position of the test contact 17 of the filter 16, improving its practicality.

[0070] After the test, the operator unplugs the power supply equipment from the socket 114, then pushes the push rod 93 to move the sliding rod 91, causing the positioning latch 92 and the locking block 65 to misalign, thus releasing the locking state. The first return spring 64 releases the stored elastic force, causing the first locking device 6 used to clamp and fix the filter 16 to move upward. Then, the travel device 11 is pushed downward, causing the travel rod 111 to push the clamping rod 67 to rotate outward, and the locking abutment 69 to contact and lock the movable latch 603 again, thus restoring the device to its initial state. At this time, the clamping rods 67 are fully extended, and the operator can directly remove the filter 16 and replace it with another filter 16, thus achieving quick disassembly, making it more convenient to use and improving the practicality of the device.

[0071] In this embodiment, the connecting device 12 includes a bottom compartment 121. A connecting seat 122 is provided at the bottom of the bottom cavity of the bottom compartment 121 near both sides. A spring telescopic seat 123 is provided at the bottom cavity of the bottom compartment 121 near the middle. A connecting plate 124 is fixedly installed on the top of the spring telescopic seat 123. A connecting contact 125 is fixedly installed at the bottom of the connecting plate 124 near both ends. The connecting contact 125 corresponds to the slot on the top of the connecting seat 122.

[0072] The output terminal of the connector 122 is connected to the input terminal of the power supply equipment via a signal connection.

[0073] When the first locking device 6 is subjected to the downward pressure of the filter 16, the downward pressure rod 63 moves down through the through hole 15 at the bottom of the limiting slide rail 5, contacts the top surface of the connecting plate 124 and pushes it down, so that the connecting contact 125 is inserted into the interior of the connecting seat 122, thereby connecting and activating the two connecting seats 122. At this time, the output end of the connecting seat 122 is connected to the input end of the power supply equipment through a signal connection, so that the power supply equipment is in the running state. This realizes that the power supply equipment will only be activated after the filter 16 is placed, avoiding the problem of increased energy consumption and excessive operating costs caused by the power supply equipment being in the running state for a long time, thus improving the practicality of the device.

[0074] The method of using this invention is as follows:

[0075] When placing the filter 16, it contacts and presses down on the top of the telescopic column 61. The telescopic column 61 moves vertically downward. During this process, as the stroke device 11 moves upward, the stroke rod 111 contacts the locking rod 69 and pushes the locking rod 69 to move. During the movement of the locking rod 69, it releases the locking state of the movable latch 603. At the same time, the clamping rod 67 rotates towards the telescopic column 61 under the elastic force of the tension spring 605, so that the top of the clamping rod 67 contacts and clamps the outer surface of the filter 16, thereby achieving fixation. This fixing method can achieve a stable fixing effect for filters 16 of various specifications and does not require additional adjustment. When the telescopic column 61 moves down and its top is flush with the top of the outer shell 1, the locking block 65 and the positioning latch 92 remain locked to prevent the elastic force of the first return spring 64 from lifting the filter 16 and causing unstable fixing. At the same time, it keeps the part of the top of the outer shell 1 that contacts the filter 16 flush. Once the device clamps and fixes the filter 16, only the first locking device 6 in contact with the filter 16 is triggered and clamps the filter 16, while the other first locking devices 6 remain in their initial state. At this time, the operator can slowly lift the entire travel device 11 by holding the grip part 113. During this process, the travel rod 111 will first contact the locking abutment 69 in the clamped first locking device 6, and release the locking abutment 69 from the locking state of the movable latch 603. The clamping rod 67 rotates and... The travel device 11 is brought into contact with the outer surface of the travel rod 111, and then the travel device 11 is slowly lifted. At the same time, the clamping rod 67 is slowly rotated toward the telescopic column 61 until the clamping rod 67 contacts the test contact 17 on the filter 16. At this time, the travel device 11 is stopped, so that the clamping rod 67 can simultaneously contact the travel rod 111 and the test contact 17 on the filter 16. Then, the power supply plug is inserted into the socket 114, so that the test contact 17 of the filter 16 can be powered and tested through the travel rod 111 and the clamping rod 67. This testing method can automatically adapt the position of the test contact 17 of the filter 16. Since the top of the clamping rod 67 is provided with a pad 604, it plays an anti-slip role when it contacts the outer surface of the filter 16, and also plays an insulating role. This prevents the current from passing through the tip of the clamping rod 67 and penetrating the outer shell of the filter 16 when the travel rod 111 is energized. Furthermore, the clamping rod 67, which is not in contact with the outer shell of the filter 16 and the test contact 17 and is in a relative position, will not make contact with each other because it is blocked by the travel rod 111.When the first locking device 6 is subjected to the downward pressure of the filter 16, the downward pressure rod 63 moves down through the through hole 15 at the bottom of the limiting slide rail 5, contacts the top surface of the connecting plate 124 and pushes it down, so that the connecting contact 125 is inserted into the interior of the connecting seat 122, thereby connecting and activating the two connecting seats 122. At this time, the output end of the connecting seat 122 is connected to the input end of the power supply equipment through a signal connection, so that the power supply equipment is in the running state, realizing that the power supply equipment will only be activated after the filter 16 is placed. After the test, the operator unplugs the power supply equipment from the socket 114, then pushes the push rod 93 to move the sliding rod 91, causing the positioning latch 92 and the locking block 65 to misalign, thus releasing the locking state. The first return spring 64 releases the stored elastic force, causing the first locking device 6 used to clamp and fix the filter 16 to move upward. Then, the travel device 11 is pushed downward, causing the travel rod 111 to push the clamping rod 67 to rotate outward, and the locking abutment 69 to contact and lock the movable latch 603 again, thus restoring the device to its initial state. At this time, the clamping rods 67 are fully extended, and the operator can directly remove the filter 16 and replace it with another filter 16, thus achieving quick disassembly and making it more convenient to use.
