Description

Technical Field

[0001] This utility model belongs to the technical field of connector manufacturing, and specifically relates to a connector life testing machine. Background Technology

[0002] The POGO PIN life tester is an automated testing device specifically designed to simulate and evaluate the insertion and removal life of Pogo Pins. Its core purpose is to verify the stability of the electrical performance (such as contact resistance and momentary power failure) and mechanical performance (such as spring force decay and wear) of Pogo Pins through thousands or even millions of repeated insertion and removal actions, thereby verifying their quality and reliability.

[0003] However, in existing technologies, the mechanical transmission components of the power source used to drive the equipment are prone to wear during long-term, high-frequency use, which leads to a decrease in repeatability and affects the accuracy and reliability of testing. In addition, high-frequency movement means frequent starts and stops, requiring a large instantaneous torque, which causes the motor coil to generate a lot of heat. As a result, the power source may experience unstable performance or even protective shutdown due to excessive temperature. Utility Model Content

[0004] (1) Technical problems to be solved This invention provides a life testing machine for connectors, aiming to solve the problem in the prior art where severe wear of the mechanical transmission components of the power source leads to poor repeatability and affects the accuracy and reliability of testing.

[0005] (2) Technical solution This utility model provides a connector life testing machine, including a base, a bracket, and a pressing structure. The base and the bracket are arranged perpendicularly to each other. A first clamp is provided on the base. The pressing structure includes a rotating component, a sliding component, and a second clamp that cooperates with the first clamp. The sliding component is located below the rotating component and its sliding direction is perpendicular to the base. The second clamp is disposed on the sliding component. The rotating component includes a turntable. A connecting member is also provided between the rotating component and the sliding component. One end of the connecting member is rotatably connected to the turntable, and the other end is rotatably connected to the sliding component, so that the rotation of the turntable can synchronously drive the sliding component and the second clamp to move up and down.

[0006] Furthermore, the rotating assembly also includes an adjusting member. The center of the turntable is provided with an adjusting groove adapted to the adjusting member. The adjusting groove is provided with a plurality of adjusting holes. The adjusting holes are located outside the center point A of the turntable. The adjusting member is provided with a connecting hole adapted to the adjusting hole. The connecting member is rotatably connected to the turntable through the connecting hole and the adjusting hole.

[0007] Furthermore, the rotating assembly also includes a drive component located on the other side of the bracket, the drive component having a drive shaft passing through the bracket and fixedly connected to the center point A of the turntable.

[0008] Furthermore, sensors are also provided on both sides of the turntable on the bracket, and the turntable has an outward-facing sensing groove, and the sensors are inductively connected to the sensing groove.

[0009] Furthermore, the sliding assembly includes two symmetrically arranged slide rails, a slider, a first slide plate, and a second slide plate. The first slide plate and the second slide plate are slidably connected to the slide rails via the slider. The end of the connector away from the turntable is rotatably connected to the first slide plate. The second clamp is located on the second slide plate. A connecting rod is also connected between the first slide plate and the second slide plate to make the first slide plate and the second slide plate slide synchronously.

[0010] Furthermore, the second clamp is detachably connected to the second slide plate. The second slide plate has a plurality of spaced first fixing holes along the sliding direction. The second clamp is screwed to the second slide plate through the first fixing holes. When the second clamp is connected to the first fixing holes at different positions, the distance between the second clamp and the first clamp is different.

[0011] Furthermore, the base is provided with first buffer members on both sides of the second slide plate, and the second slide plate is provided with second buffer members corresponding to the first buffer members. The second buffer members slide against the first buffer members as the second slide plate moves.

[0012] Furthermore, the second fixture is provided with at least one workstation, and the number of workstations on the first fixture corresponds to the number of workstations on the second fixture.

[0013] Furthermore, multiple second fixtures are configured corresponding to the first fixture, and the number of workstations on the multiple second fixtures is different.

[0014] Furthermore, the first fixture and the second fixture are respectively provided with a first positioning component and a second positioning component adapted to the workstation. After the workpiece is installed at the workstation, the first positioning component and the second positioning component are respectively located at the workstation and screwed and fixed to the first fixture and the second fixture.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By simultaneously setting a rotating component and a sliding component on the bracket, and connecting the rotating component and the sliding component with a connecting piece, the rotation of the rotating component enables the linear movement of the sliding component. This changes the existing technology that only sets a linear motion power source to drive the second fixture to move towards the first fixture. It effectively avoids the problem that the mechanical transmission components of the power source will wear out severely under long-term high-frequency linear motion, resulting in poor repeatability and affecting the accuracy and reliability of the test.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1-4 As shown, this utility model provides a connector life testing machine, including a base 1, a bracket 2, and a pressing structure. The base 1 and the bracket 2 are arranged perpendicularly to each other. The base 1 is provided with a first clamp 11. The pressing structure includes a rotating component 3, a sliding component 4, and a second clamp 5 that cooperates with the first clamp 11. The sliding component 4 is located below the rotating component 3 and its sliding direction is perpendicular to the base 1. The second clamp 5 is disposed on the sliding component 4. The rotating component 3 includes a turntable 31. A connecting member 6 is also provided between the rotating component 3 and the sliding component 4. One end of the connecting member 6 is rotatably connected to the turntable 31, and the other end is rotatably connected to the sliding component 4, so that the rotation of the turntable 31 can synchronously drive the sliding component 4 and the second clamp 5 to move up and down. The second clamp 5 is used to place the connector 53 to be tested, and the first clamp 11 is used to assemble the contact surface 112 that mates with the connector 53. In this embodiment of the utility model, the connector 53 is a Pogo Pin connector, and the contact surface 112 can be a charging contact, a PCB pad, etc. During testing, the rotation of the turntable 31 exerts an upward pulling force on the connector 6, causing the sliding assembly 4 and the second clamp 5 to move synchronously away from the first clamp 11 under the action of the connector 6, thus separating the second clamp 5 from the first clamp 11. Then, the corresponding connector 53 and contact surface 112 are respectively installed into the second clamp 5 and the first clamp 11. Next, the turntable 31 is driven to rotate. During the rotation of the turntable 31, one end of the connector 6 connected to the turntable 31 rotates synchronously, while the other end is restricted by the sliding assembly 4, exerting an upward or downward pushing force on the sliding assembly 4. This causes the second clamp 5, located on the sliding assembly 4, to move linearly up and down on the bracket 2, bringing the connector 53 inside the second clamp 5 into contact with the contact surface 112. Upon contact, the Pogo Pin inside the second clamp 5 is compressed, and the spring activates. When the second clamp 5 moves upward again, one insertion and removal cycle is completed. This process is repeated thousands or even millions of times to evaluate the Pogo Pin. The lifespan of the pin insertion / removal mechanism.

[0030] Specifically, such as Figure 5 As shown, the rotating assembly 3 also includes an adjusting member 32. The center of the turntable 31 has an adjusting groove 311 adapted to the adjusting member 32. The adjusting groove 311 contains several adjusting holes 312. The adjusting member 32 has connecting holes 321 adapted to the adjusting holes 312. The connecting member 6 is rotatably connected to the turntable 31 through the connecting holes 321 and the adjusting holes 312. The adjusting holes 312 are located outside the center point A of the turntable 31. Therefore, the connecting member 6 is eccentrically screwed to the turntable 31. The eccentric structure and the sliding assembly 4 are used to convert the rotational motion into rotational motion. Compared to existing technologies that use cylinders, servo motors, or stepper motors for single linear motion, this invention effectively avoids the problem of severe wear on the mechanical transmission components of the power source under prolonged high-frequency linear motion, which leads to decreased repeatability and affects test accuracy and reliability. Furthermore, high-frequency motion implies frequent starts and stops, requiring large instantaneous torque, causing the motor coils to generate a large amount of heat. This can lead to unstable performance or even protective shutdown of the power source due to overheating. Therefore, this invention also avoids a series of problems caused by the power source, such as decreased production efficiency and increased maintenance costs.

[0031] Furthermore, such as Figure 6As shown, the rotating component 3 also includes a driving component 33, which is located on the other side of the bracket 2. The driving shaft of the driving component 33 passes through the bracket 2 and is fixedly connected to the center point A of the turntable 31, so that when the driving component 33 rotates, it can synchronously drive the turntable 31 to rotate, thereby providing sliding power to the sliding component 4. By setting the driving component 33 and the turntable 31 on both sides of the bracket 2 respectively, the overall structure layout of this utility model can be made neater and more beautiful. In this embodiment, the driving component 33 is a rotary motor.

[0032] Preferably, such as Figure 5 As shown, several adjustment holes 312 are symmetrically arranged around the center point A within the adjustment groove 311. When the connector 6 is connected to different adjustment holes 312, the movement distance of the second clamp 5 is different. Therefore, when the connector 53 to be tested has different sizes, the user can change the movement distance of the second clamp 5 by adjusting the connection of the connector 6 to the adjustment holes 312 at different positions, so that the connector 53 installed in the second clamp 5 is compatible with the contact surface 112 located in the first clamp 11. This makes the machine suitable for testing connectors 53 of various sizes, with a wider range of applications, better meeting the diverse needs of users, and avoiding the limitation of testing only one type of connector 53. Moreover, compared with the prior art, which directly controls the movement distance of the second clamp 5 by the movement distance of the output shaft of the power source, the structure of adjusting the movement distance of the second clamp 5 by connecting to different adjustment holes 312 is more stable, more reliable, and easier to adjust.

[0033] Furthermore, it should be noted that by symmetrically arranging the plurality of adjustment holes 312 around the center point A, the adjustment component 32 can be directly assembled without considering the installation direction during installation, thus improving assembly efficiency. Simultaneously, to improve the stability and reliability of the connection between the connector 6, the adjustment component 32, and the turntable 31, a strip-shaped through groove 322 is provided at the end of the adjustment component 32 away from the connection hole 321. The through groove 322 corresponds to the adjustment hole 312. During installation, when the connection hole 321 of the adjustment component 32 is screwed into the adjustment hole 312 located to the left of the center point A... The through groove 322 corresponds to several adjustment holes 312 on the right side of the center point A. At this time, bolts can be used to screw the adjustment member 32 to the several adjustment holes 312 on the right side of the center point A through the through groove 322, so that both ends of the adjustment member 32 are screwed to the turntable 31, improving the balance and stability of the connection. When the bolt on the connector 6 loosens from the adjustment hole 312, the adjustment member 32 will not fall off immediately, thus giving the user time to discover the loosening of the machine connection and avoiding damage to the connector 53 or other components when the adjustment member 32 falls off.

[0034] Furthermore, such as Figure 3-4 As shown, sensors 21 are also provided on both sides of the turntable 31 on the bracket 2. The turntable 31 has an outward-facing sensing groove 313. The sensors 21 are inductively connected to the sensing groove 313. When the turntable 31 rotates, when the opening of the sensing groove 313 corresponds to the position of one of the sensors 21, it means that the contact surface 112 in the first clamp 11 and the connector 53 of the second clamp 5 are in a contact / separation state. When the turntable 31 continues to rotate, so that the opening of the sensing groove 313 corresponds to the position of the other sensor 21, it means that the contact surface 112 in the first clamp 11 and the connector 53 of the second clamp 5 are in a separation / contact state. Thus, the turntable 31 rotates once, and the first clamp 11 and the second clamp 5 complete one insertion and removal. From this, the number of rotations of the turntable 31 and the number of insertions and removals of the first clamp 11 and the second clamp 5 can be calculated, and the service life of the connector 53 can be determined.

[0035] Furthermore, this utility model also includes a controller 7, which is located on the side of the bracket 2 and electrically connected to the drive component 33. The controller 7 can be used to control the start and stop of the drive component 33 and set parameters such as the number of insertions and removals. The controller 7 is also connected to the sensor 21 and sends instructions to the drive component 33 by receiving signals from the sensor 21 to ensure the accuracy of the drive component 33's operation. When a fault occurs after the test or during the test, the equipment automatically stops and generates a test report, recording data such as the total number of tests, the number of qualified / failed tests, and the resistance change trend.

[0036] Furthermore, such as Figure 1 , Figure 7 As shown, the sliding assembly 4 includes two symmetrically arranged slide rails 41, a slider 42, a first slide plate 43, and a second slide plate 44. The first slide plate 43 and the second slide plate 44 are slidably connected to the slide rails 41 via the slider 42. The end of the connecting member 6 away from the turntable 31 is rotatably connected to the first slide plate 43. The second clamp 5 is located on the second slide plate 44. A connecting rod 45 is also connected between the first slide plate 43 and the second slide plate 44 to make the first slide plate 43 and the second slide plate 44 slide synchronously. The first slide plate 43 has a plurality of second fixing holes 431 spaced apart along the sliding direction. The connecting rod 45 is screwed to the first slide plate 43 through the second fixing holes 431. When 5 is connected to different second fixing holes 431, the distance between the second slide plate 44 and the second clamp 5 located on the second slide plate 44 and the first clamp 11 can be changed. Thus, when testing connectors 53 of different sizes, the distance between the first clamp 11 and the second clamp 5 can be changed by adjusting the position of the connecting rod 45 and the second fixing hole 431 on the first slide plate 43. This not only makes adjustment convenient but also allows for more precise adjustment. Therefore, by setting the first slide plate 43 and the second slide plate 44 separately, this invention avoids the need for a structure using only one slide plate, thereby meeting the user's needs for multiple adjustment methods and expanding the applicability of the connectors 53 that this invention can test.

[0037] Furthermore, the second clamp 5 is detachably connected to the second slide plate 44. The second slide plate 44 has a plurality of spaced first fixing holes 441 along the sliding direction. The second clamp 5 is screwed to the second slide plate 44 through the first fixing holes 441. Similarly, when the second clamp 5 is connected to the first fixing holes 441 at different positions, the distance between the second clamp 5 and the first clamp 11 is also different. This further enhances the accuracy of the distance adjustment between the first clamp 11 and the second clamp 5 of this utility model, making the first clamp 11 and the second clamp 5 more compatible.

[0038] Preferably, such as Figure 7 , Figure 8 As shown, the base 1 is provided with first buffer members 12 on both sides of the second slide plate 44, and the second slide plate 44 is provided with second buffer members 442 corresponding to the first buffer members 12. The second buffer members 442 slide and abut against the first buffer members 12 as the second slide plate 44 moves. When the first clamp 11 slides too far and becomes incompatible with the second clamp 5 due to mechanical wear or sudden situations, the first buffer members 12 and the second buffer members 442 can effectively block the impact of the gravity and thrust of the second clamp 5 and the sliding component 4 on the first clamp 11, thereby protecting the machine from excessive damage and reducing maintenance and material costs to the greatest extent.

[0039] Preferably, the second slide plate 44 is further provided with an "L"-shaped alignment member 443, the alignment member 443 is provided with an alignment hole 4431, and the base 1 is provided with an alignment rod 13 corresponding to the alignment hole 4431. When the second clamp 5 moves and approaches the first clamp 11, the alignment rod 13 will pass through the alignment hole 4431 first. At this time, it means that the positions of the first clamp 11 and the second clamp 5 are correctly corresponding. When the alignment rod 13 does not correspond to the alignment hole 4431, the second slide plate 44 will be blocked by the alignment rod 13, and the machine can issue a prompt sound and stop operation so that the user can make timely adjustments and avoid damage to the machine caused by continuous incorrect sliding or affect the production progress due to interruption.

[0040] Furthermore, such as Figure 9 As shown, the second fixture 5 is provided with at least one station 51. The number of stations 51 on the first fixture 11 corresponds to the number of stations 51 on the second fixture 5. That is, the second fixture 5 and the first fixture 11 can be provided with 1, 2, or 5 stations, etc. The specific number can be freely adjusted according to the user's production needs. By setting multiple stations 51, multiple connectors 53 can be tested simultaneously in one test, improving testing efficiency. In this embodiment, the second fixture 5 preferably has 5 stations 51 to facilitate improved testing efficiency and reduced energy consumption.

[0041] Furthermore, such as Figure 11 As shown, multiple second fixtures 5 and multiple first fixtures 11 are configured accordingly. The number of workstations 51 on the multiple second fixtures 5 is different, which makes it convenient for users to adjust the number of tests. They only need to disassemble and replace the first fixture 11 and the second fixture 5, making it more flexible and convenient to use and improving the user experience.

[0042] Preferably, such as Figure 9-10 As shown, the first fixture 11 and the second fixture 5 are respectively provided with a first positioning element 111 and a second positioning element 52 adapted to the workstation 51. After the workpiece is installed on the workstation 51, the first positioning element 111 and the second positioning element 52 are respectively located on the workstation 51 and screwed and fixed to the first fixture 11 and the second fixture 5. Here, the workpiece refers to the connector 53 and the contact surface 112. Through the setting of the first positioning element 111 and the second positioning element 52, the connector 53 is fixed between the second fixture 5 and the second positioning element 52, and the contact surface 112 is fixed to the first fixture 111. 1. Between the first positioning member 111 and the second clamp 5, to prevent the contact surface 112 and the connector 53 from becoming loose or moving, thereby improving the stability and reliability of the test. The first positioning member 111 is provided with a first through hole 113 that matches the contact point of the contact surface 112, and the second clamp 5 is provided with a second through hole 521 that matches the contact point of the connector 53. After installation, the contact point of the contact surface 112 extends through the first through hole 113 to the first positioning member 111, and the contact point of the connector 53 extends through the second through hole 521 to the second clamp 5, so as to facilitate contact with the contact point of the contact surface 112.

[0043] The working principle of this utility model is explained in detail below: During testing, the connector 53 to be tested and its mating contact surface 112 are respectively installed on the second clamp 5 and the first clamp 11. Then, the drive unit 33 is activated, and the turntable 31 rotates under the action of the drive unit 33. The rotation of the turntable 31 drives the connector 6 to rotate. At this time, the first slide plate 43 and the second slide plate 44 connected to the other end of the connector 6 will be simultaneously subjected to an upward or downward pulling force or pushing force, which causes the first slide plate 43 and the second slide plate 44 to move up and down along the slide rail 41 under the action of the slider 42. This causes the second clamp 5 to move up and down continuously relative to the first clamp 11, so that the connector 53 on the second clamp 5 repeatedly contacts or separates from the contact surface 112 on the first clamp 11 to complete the insertion and removal action.

[0044] The innovation of this utility model lies in the simultaneous arrangement of a rotating component and a sliding component on the bracket, with a connecting piece rotatably connecting the rotating component and the sliding component. This allows the rotation of the rotating component to achieve the linear movement of the sliding component, changing the existing technology that only uses a linear motion power source to drive the second fixture to move towards the first fixture. This effectively avoids the problem of severe wear of the mechanical transmission components of the power source under long-term high-frequency linear motion, which leads to poor repeatability and affects the accuracy and reliability of the test.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
